"Hogwarts: The Slytherin of Sentiment" by Fan Yuanchu. It is a light novel/derivative doujinshi novel. It has intelligence, decisive killing, wizardry, and magical elements. It is finished and can be enjoyed without worry.
In 1971, a group of young wizards boarded the train to Hogwarts with great anticipation.
A young wizard in the carriage pointed his wand at himself, waving his hand from time to time, frowning and muttering.
"Drill the heart and gouge the bones!"
"Heart Piercing Bone Cutting!"
I hope you will like this book.

The following is a detailed introduction of these novels:
1."A Collapsed Hogwarts": Not bad Harry Potter doujinshi. He doesn't take the usual path. He has brains, logic, and intelligence. His character creation is also very good.
2.<<Dressed as Wu Zetian's Daughter and Spoiled by the Group>> The woman standing in front of you:
[Family background isn't considered strong]: Grandfather is the emperor, father is the emperor, mother is the emperor, brother is the emperor. If nothing goes wrong, she might also be the emperor.
Emperor Gaozong of the Tang Dynasty regarded her as a pearl in his palm. Empress Wu loved her like a treasure in her arms. She was the young Qiansui of the common people and the Marquis of Ten Thousand Families of the Tang Dynasty.
[Not too good looking: Enchanted, the flower of Luoyang.] She was the dream lover of the nobles and the princess consort of the princes of various countries.
Marriage Is Not Noble: "On the day of the wedding, Chang 'an City was covered with flowers and trees. The dowry line extended from the Daming Palace to the Xuande Gate.
[Not Many Titles: Spiritual Mentor of the Early Tang Dynasty's literary world, Uncrowned Empress of the overseas Han people, Chief Planner of the Dragon Coup, Founder of Women's Status, Helmsman of the Prosperous Dynasty, Person in Charge of the Imperial Power Change…]
She was a princess among princesses, a dragon among dragons and phoenixes.
3."A Professor of the History of Magic at Hogwarts": After leaving Hogwarts for many years, Master Fenister Black never thought that he would one day receive an invitation from the Headmaster of Hogwarts to return to this school and take up the position of Professor of the History of Magic.
Mr. Blake had no objection to this, but some of the little ones might not have it easy.
"Potter, what was your happiest moment in seven years?"
Harry Potter smiled."It was when I found out Sirius was my godfather."
"Then when were you the most unhappy?"
Harry Potter paused, remembering with some horror,"When I found out that Professor Black was Sirius's brother... Merlin, he was a demon!"
Dear Harry Potter will never forget the gloomy Professor's face that had appeared behind him that summer when he had been surprised to see Sirius at number twelve Grimmauld Place.
As well as the paper that didn't have many marks.
And the scene of him and Sirius being scolded together.
4."Three Kingdoms 'I Do Logistics for the Prime Minister": Six trips to Qishan were all due to the failure of logistics. As a transmigrator, how could the Prime Minister's fans let the Prime Minister be dragged down by a pig teammate? First, he had to make paper, then print books, farm, store grain, forge iron, recruit soldiers, pacify the barbarians, make salt, open mail and set up post stations…
Materials, money, and food piled up into mountains, and weapons and armor were filled to the brim.
Tell the Prime Minister that we can't afford to let go of the military supplies and that we should hurry up and fight a battle.
5."Lord of the Mysteries: Yao Guang": Female Lead, Amon as Male Lead, No Emotional Lines
The female lead had transmigrated before Klein, so she didn't know the plot. Her personality wasn't used to it at first, but she grew as the text unfolded.
Stabilize
6."After Wu Zetian Reborn as Lu Zhi": In the first year of Shenlong, Wu Zetian passed away in Shangyang Palace.
When she woke up again, she had transmigrated into Lu Zhi, who was in her thirties. She had just ended two years of being a hostage and was sent back to her husband Liu Ji's army by the Chu army.
At this time, Liu Ji had not changed his name and was not called Liu Bang yet.
Wu Zetian laughed loudly.
Everyone is calling me the second Empress Lu, so I'll experience how to be Empress Lu herself!
[Lu Zhi picked up the horsewhip and whipped it down at Liu Jipao's feet.
"Although victory and defeat are common in a military, this whip is for the casualties of the Battle of Peng City."
[Lu Zhi pointed at Shen Shiqi and said with a smile,
"One day, people will accuse you and me of not cultivating our morals and causing chaos in the palace.
Don't panic when the time comes. It's proof that I've reached the peak of power."
[In the face of Princess Lu Yuan, the love-minded daughter who refused to come to her senses and wanted to marry the traitor, Lu Zhi sighed at Bo Ji.
"The world is sober. You should go and persuade her."
[Looking at Concubine Qi's gloomy face, Lu Zhi laughed instead of getting angry.
"The Emperor was badly beaten by Chief Maodun and almost starved to death in Ping Cheng.
With such exuberant energy, it's better to think about how to suppress the Han court."
[Lu Zhi rolled his eyes. He had heard such words like "Xiaohui is not like me" and "Ruyi is like me" in his previous life. Whenever the old Emperor wanted to change the Crown Prince, there was nothing new to say.
Even if the children are not like you, what does it matter?
As long as they are like me, regardless of whether it is a son or a daughter, they might be able to become the eternal emperor.]
---------------
The female lead of this article did not have a CP and was focused on her career. There were not many palace fights.
7:"The Peace-loving Necromancer at Hogwarts": This is the most original Doujin in recent years. Many times, I suspected that the author first wrote an English version and then translated it into Chinese for us to see. This is absolutely lustful!
8. The Way Home to Hogwarts: The Way Home to Hogwarts is an excellent Harry Potter fan novel. In this book, the author showed his deep understanding of the world of Harry Potter and his unique creativity. Unlike other doujinshi novels, this book did not focus too much on the protagonist's acting. Instead, it supplemented and expanded the Harry Potter world through the perspective of the protagonist as a civilian wizard. This unique setting made the book more realistic and interesting. The protagonist's personality and intelligence were outstanding, leaving a deep impression on everyone. At the same time, the author's writing style was also very experienced, and the characters in the original work were very accurate. All in all,"The Way Home to Hogwarts" was a highly recommended book. Whether it was for Harry Potter fans or those who liked fantasy and were eager to explore the Wizarding World, it was a very suitable book to read.
9."Nine Years of Suppressing Demons, I Became the World's Number One": The Immortal's Journey Record
The colorful dress drags the wide belt, flutters the wind to ascend to heaven. The immortal holds six chopsticks, and the gods and devils attach themselves to peace.
Jiang Yu, a warlock who had just left the mountain gate, came to the Xuzhou Prefecture in southern Sichuan in order to find the whereabouts of his master's disappearance. He accidentally obtained the sect's supreme treasure, the Wordless Heavenly Book, the Heaven and Earth Immortal Record, and embarked on a journey.
Send the demon seed, break the dream, go to the Ruins of End, see the double screen, kill the hungry ghost, trap the god, ascend the immortal line!
Jiang Yu: All the things in the past are like dying yesterday, and all the things in the future are like living today!
10: Harry Potter and the Old Ones: Playing with Harry is quite interesting, but Cthulhu and the protagonist's ambition are just so-so
11:"Please Follow the Cultivation Script": No CP, First Female Lead
Ye Wuchen, male, possessed the Immortal Cultivation System. He was considered the most likely person in the Immortal Cultivation World to eliminate the Demon Lord because the Heavenly Axiom said so. There was only one problem.
It was a girl called Jiang Li.
Mistakes came one after another. Why was there nothing that was the same as what the Heavenly Dao said? Why did she become a bandit? Going into business? Why did he go to grave robbing?
Can't we follow the script of cultivation!
12:"The Capable Gin Is Melancholic Today":"Daily + Relax"
In her previous life, Shiroishi Akeizawa was a social animal. She was reborn as a primary school student in the countryside in Japan. Her lazy life was forcefully interrupted at the beginning. A man with long silver hair named Kurosawa became her new father. Shiroishi Akeizawa was miserably dragged back to the city to go to school.
What happened to Tokyo? What kind of place was Mi Hua City?
What was that? She wasn't reborn in Tokyo, but Detective Conan?
Wasn't her father the Black Swamp Formation? What was this?
……
From then on, Bai Heize started a happy childhood where he fought wits and courage with his father and led the detective team to cause destruction everywhere.

13: The Aphasia at Hogwarts: Status: In Series (290,000 words)
[Description: Good news, reborn in the magical world, with a talent that is on par with Grindelwald Dumbledore. Bad news is that a mute can't speak, so he learns Silent Magic directly. Main storyline.]
Suit to the original novel party, follow the original plot while being innovative
The lovelest Hermione
The description of magic is very good! A reasonable description of spells and principles, bringing us into the magical world. The writing is superb!
14: Hogwarts: The Dominating Demon from the Chainsaw Man: After the Dominating Demon was exiled to the Wizarding World and became a Demon Man surnamed Evans
The story of Harry Potter has become very different
Snape became a war hero, smiling at Gryffindor
Harry Potter's wand glowed green and barked in his roommate's bed late at night
The old man of Nurmengard had run away,
The species of animals in the forbidden forest are dwindling
Manar S. Evans."They are wings that obey Manar! Moreover, we have to hunt demons together!"
"Building a Sect from Scratch": Xiao Ranran Transmigrated to the Cultivation Continent.
Just as she thought that she was about to start drawing qi into her body with the female lead's script, cultivate and ascend to the peak of her life, the system told her,"Our mission is to build a sect, do more good deeds, and take in disciples to spread the mental cultivation method so that everyone can use better mental cultivation methods…"
Therefore, Xiao Ranran looked at the dilapidated house and was not surprised to hear the system say,"The houses here are too dilapidated. Host, remember to cut down the trees, dig up the soil, pull the grass, and repair them. The spiritual rice we provide is not enough for you to eat, so remember to open up wasteland and farm. The spiritual stones we give are not enough. You have to think of a way to earn money yourself."
Later, Xiao Ranran looked at the little radish head in front of her and fell into deep thought. What kind of position should she use to dig so that she would not tarnish her reputation and still appear like an immortal?
1. Farming + Construction + Cultivation, System
2. In the early stage, it was more about infrastructure + farming, and in the later stage, it was more about cultivation.
3. There's a male lead, but there's not much screen time.
4. Female Lead Wearing, Zero Foundation Immortal Cultivation, Requires Time to Catch Up to Others
Hogwarts: The Intertwined Universe of Harry Potter
What would happen when characters from countless versions and various timelines gathered together?
In this era of magic, everything would be different.
Ják:(#) I heard that I'm the main character.
17:"I Rely on Qin Shihuang to Become a God":"The Knowing Bird can see the future and predict the future. Even though the Ruler has Zhao Gao and Li Si, the biggest demon star is you, Empress."
Bai Tao was originally a fox demon who had only cultivated for a hundred years. She had transformed into a human form and mingled in the palace. She wielded power and was even loved by Qin Shihuang.
Hearing this, she opened her eyes and smiled coquettishly."What Fiend Star? When Ruler and I first worshipped the ancestral temple, there was a strong wind and all the ancestors showed their spirits. That day, it rained heavily and soon, snow covered the mountains. Next year, the rivers and canals were opened and the Guanzhong granaries were rich. In the blink of an eye, they had swallowed the six countries."
"I have known the ruler since I was young in Zhao and have been with him for more than 20 years. In the blink of an eye, time has passed and he is about to go to Mount Tai to worship the heavens. Ruler said how lucky I am, he even said this empress is his auspicious sign."

Food Guide:
1. Monsters + history = fiction. You can make suggestions, but if you make mistakes, you win.
2. The characters have grown, and there are no supporting characters in this book.
This book has been edited many times, and the plot is quite different from the pirated version.
3. The frequency of updates is the first round, the first round is updated every other day, and the second round is updated every other day.
"Days in Hogwarts": The protagonist who was born after transmigrating to HP. The cheat is Magic Perception. The main character had his own understanding of magic, and he was currently focusing on magic runes, spells, and alchemy. The main character, Le Ziren, was also a kind person. His love line was especially warm, and his description of the original main characters was not bad. The disadvantage was that he was too muddled in the first year, but there was a big improvement later on.
19."Elegy of the North": The dark curse of eternal night is in the north, and the scorching day is in the south.
The darkest abyss of sin and the lightest song of all things, these two completely different extremes actually coexisted.
The Canfit Continent! How do you balance this concerto of love and hate?
The young Parmar held tightly to the life she had stolen, devoutly kissing every handful of blood-soaked dust under her feet, sending off one close friend after another.
Who would play the last elegy for her?

Hogwarts: The Ancient Male Veela Doesn't Want to Be Headmaster, by Marquis Watergate
The following is a detailed introduction of these novels:
1:"I've been expelled from Hogwarts?" Raven's new book was still a Harry Potter fanboy.
This author's previous book,'A Certain Magic' could be considered one of the best Harry Potter Doujinshi works. He could finish seven years without collapsing. The original plot and setting were also very detailed, and there were no problems with the logic.
I followed up on a certain magic until the end. This author's ability to follow current events is extremely strong. The experience of following up is very good. Those who like HP Doujinshi can enter.
2."Grindelwald's Favorite I Goed to Hogwarts":"Gancao", a book I started reading at the end of 2021. The setting is very novel, and the author's writing rhythm and style are quite good. However, I don't know why it only recently received the Excellent Award.
Dumbledore and Grindelwald are online at the same time, Riddle can't do anything but he's trying to do something, and there's a character from a magical creature like Aurelius Dumbledore in it, which is nice.
It was still in the midst of being serialized, but there were already quite a few of them. It was worth it!
3."A Collapsed Hogwarts": Not bad Harry Potter doujinshi. He doesn't take the usual path. He has brains, logic, and intelligence. His character creation is also very good.
4."A Professor of the History of Magic at Hogwarts": After leaving Hogwarts for many years, Master Fenister Black never thought that he would one day receive an invitation from the Headmaster of Hogwarts to return to this school and take up the position of Professor of the History of Magic.
Mr. Blake had no objection to this, but some of the little ones might not have it easy.
"Potter, what was your happiest moment in seven years?"
Harry Potter smiled."It was when I found out Sirius was my godfather."
"Then when were you the most unhappy?"
Harry Potter paused, remembering with some horror,"When I found out that Professor Black was Sirius's brother... Merlin, he was a demon!"
Dear Harry Potter will never forget the gloomy Professor's face that had appeared behind him that summer when he had been surprised to see Sirius at number twelve Grimmauld Place.
As well as the paper that didn't have many marks.
And the scene of him and Sirius being scolded together.
5."A Magical Journey from Azkaban": Harry Potter Doujinshi. The protagonist starts in Azkaban. The cheat is similar to a simulation. I'm not a fan of HP, but it's not bad to read. Those who like HP can read it.
[Shimeng's score: 8.5]
6."Hogwarts 'Nature's Messenger": Hope had always thought that he was just an ordinary child with superpowers. Suddenly, he was fooled by the Hogwarts notice brought by the owl. What was even more ridiculous was that his parents had hidden it from him for eleven years. Seeing that his parents had given him a lot of pocket money, the kind Hope chose to forgive him. Gradually, as Hope continued to explore the wizarding world, he realized that his bloodline was not so simple...
7."The Way Home to Hogwarts":"The Way Home to Hogwarts" is a Harry Potter fan novel that is largely faithful to the original novel. The plot was compact and logical, making one feel as if they were in the world of Harry Potter. The author was also very successful in shaping the characters. He vividly restored the characters in the original work. Their personalities and behaviors were very close to the original work. In addition, the author's writing style was experienced and the narrative was smooth. It was very comfortable to read. The rhythm of the entire book was just right, so that people would not feel that it was too slow or too compact. All in all, this book is a great Harry Potter doujinshi novel and worth reading.
8."Harry Potter and the Old Ones": Setting World: Harry Potter Doujinshi
[HP Doujin][Cthulhu Element][No Female Lead]
[Points: (Full marks: 100): 85]
[Single comment: This is the first time I've seen a protagonist who can make Dumbledore's blood pressure so high. Examiner, are you interested?] I have vulgar content?
9. Hogwarts: My Name Is the Unforgivable Curse: 4 stars for now.
It's definitely a masterpiece
10:"I, Hogwarts Second Month"
[Constitution:HP]
[Description: Transforming into Owen Sanchez in the HP world. The first chapter is a zzzq world. All the original characters have been modified by zzzq. In the end, when I woke up, I entered the second chapter of the normal process. To be honest, this setting is as pure as not having any gimmicks. Other than the various abstractions described in the beginning of the book, I can't see how this week's goal affects the plot at all. It's inexplicable.]
11: Hogwarts: This Wizard Is Unscientific: HP Doujin
I really like his setting where magic involves emotions. I can also explain why there are white magic and black magic. I just don't know if this is the original setting.
"I Add Points to Talent at Hogwarts": The protagonist who was born after crossing HP. The cheat was to add points to talent. The main character of Ravenclaw. It was worth mentioning that Neville had a good relationship with Hannah after entering Hufflepuff. The main character had begun to expand his worldview. It looked very grand. On the whole, it was a warm and happy HP fan.
13:"Hogwarts: And You're Not a Dark Wizard": Who said my book list didn't have the Dark Stream? Isn't it here? The protagonist is black-hearted and framed. He's a great villain, a new generation of Dark Lord, and there's no female protagonist. Take a look, rating 4.5

16:"People at Hogwarts are blocked by werewolves at the beginning": Li Lin, who has only watched Harry Potter movies, has come to this magical world that is more inclined to novels.

Hermione, the tattletale, Ron, who wasn't so stupid,
The understanding Harry, the arrogant and eccentric Draco
.......
The burly, unrefined Slytherin
The eccentric Ravenclaw, who did not have the upper hand
The gossipy, not-so-honest Hufflepuff
Gryffindor who was disobedient to the point of being annoying
Everything made him feel particularly uncomfortable
What surprised him even more was that the game he played before he transmigrated had become his cheat.
In order to collect the other parts of the game
He began to travel through other fantasy worlds in his spare time.
However, the ridiculous thing was that fantasy worlds did not only refer to movies and television dramas.
The animation was also included.
"American Horror Story","The Academy of Good and Evil Magic","Twilight","Light Warrior"…
Ps: This game was created by the author, and it uses part of the magical awakening setting.

Well, it could be characters like Draco Malfoy. In the original series, he had his moments of growth and in fanfics, he might be one of the main Slytherins to defend Hogwarts. Maybe he finally realizes the importance of the school and his own values change. He could be joined by other Slytherins who were perhaps overlooked in the official story but show their true courage in the fanfic.
One common theme is the struggle against prejudice. Since Slytherin has a reputation for being the 'evil' house, Harry often has to fight against the preconceived notions of others. For example, in many fanfictions, the Gryffindors are initially suspicious of Harry being in Slytherin.
Another theme is loyalty. He has to decide who he is loyal to - his house, his friends, or his own beliefs. In some fanfictions, he might face a dilemma where his loyalty to Slytherin clashes with his friendship with students from other houses. This creates a lot of interesting plot twists.
One common theme is the struggle for acceptance. Since Slytherin is often seen as the more 'ambitious' and sometimes 'dark - leaning' house in the Harry Potter universe, a pregnant Slytherin might face more judgment. So, the character often has to fight for acceptance from her peers and family.
In 'Harry is a Slytherin' fanfics, a frequently seen theme is the re - evaluation of Hogwarts houses. Harry's presence in Slytherin makes people question the stereotypes. Family heritage can be a theme too, as Slytherin has a certain reputation related to pure - blood families. Another theme is the forging of new loyalties. Harry has to decide who to trust within Slytherin, which is different from his experiences in Gryffindor. And of course, the theme of personal growth as Harry develops in an environment that is initially foreign to him.
Another theme is friendship. Harry forms new friendships in Slytherin that he might not have had in Gryffindor. These friendships often cross the traditional house boundaries and are quite interesting to read about. For example, he might become friends with some of the more complex Slytherin characters who have their own motives and backstories. Also, the theme of self - discovery is prominent. Harry discovers new aspects of his magic and personality as he is in a different house environment.
Another theme is loyalty. Despite the reputation of Slytherin sometimes being seen as self - serving, fanfics often show the OC's loyalty to their friends or house mates. For example, they might stand up for a fellow Slytherin in a difficult situation. It also shows that loyalty can be complex and not always straightforward. Moreover, redemption is a theme too. Some Slytherin OCs start off with a not - so - great reputation but through their actions and growth, they seek redemption and to change others' perception of them.
