The story is set in a world full of demonized immortals. After the protagonist transmigrated to this world, he discovered that he could absorb the characteristics of demons through the cheat card BUG, thus achieving immortal cultivation without any cost.

The author cleverly combined the immortal world and the sorcerer world to create a unique world view. The story started with the Undead Immortal entering the Sorcerers World by mistake.

The author's writing was smooth and his thoughts were clear, allowing the readers to easily immerse themselves in it. In short, this book was not only an excellent wizarding cultivation, but also a fascinating adventure story. If you're interested in the subject of wizard cultivation, then from the Undead Immortal is definitely not to be missed. 3."Starting from the Heavenly Gates": The story of a plane merchant! The protagonist is very stable and logical. 4."The Post-Transmigrator Era":"I'm a student, can you give it to me?" He brought Guo Junqi a second-hand system. This system brought him literary works from another world and could bring him through these worlds. However, these worlds were all second-hand, and the other transmigrators had left their traces behind. There was Huang Feihong, who was open-minded and knowledgeable. There was also Ye Wen who practiced boxing and used a spear. He was "half-human, half-ghost, the best spear master"… 5."From a Fisherman to Immortal Cultivation":"From a Fisherman to Immortal Cultivation" is a delightful novel. The author skillfully incorporated funny and humorous elements into the subject matter, making the story even more interesting. The protagonist, Su Ping, transmigrated. 6."The Ultimate One Dao Fruit":"The Ultimate One Dao Fruit" was a very outstanding magic medicine (Dao fruit) genre novel. Although the author was above average in terms of writing, the plot flowed smoothly and made people feel very comfortable reading it. The protagonist's cheat was continuously developed. Not only could he record his own proficiency, but he could also predict the opponent's flaws in battle. Moreover, this golden finger was a karmic weapon that could trace the heroes in the protagonist's memories. The main character and the main branch of his family were on equal footing. He held many trump cards and absorbed nutrients to grow. The author created a new Sequence, allowing the protagonist's cultivation path to have a new development. Although the title was easy to skip, the content was very interesting, and it was a little funny. Overall, this book was a good novel that was highly recommended. 7."Conquering the World from the Mythical Three Kingdoms": Grain, can be considered as Yuri God Three's doujinshi. It's a little noob, but it's not bad. It barely wrote its own style and can be used as a spice during the book shortage. [Disadvantages: A common problem of new authors. They dare to act rashly with passion. A product that hasn't been edited is destined to be superficial in terms of plot and character.] One thing that had to be ridiculed was that the various settings were clearly biased towards the military and political type of monarch, but the author's imagination was so wild that he wanted the protagonist to go through the military situation, which made people feel powerless to complain. Fortunately, the author's brain was still normal. He just treated this as the hysteria of the protagonist's chuunibyou disease. The latest chapter was changing into a military strategy. 8."The Immortal Taoist in the Wuxia World": A in the early stage, final score will be seen later. This book is too folk and too spicy, but the middle is too big 9."I Can Upgrade My Goldfinger Every Month":"I Can Upgrade My Goldfinger Every Month" was an exciting new book. The author displayed a genius writing style, allowing the readers to feel a sense of humor while reading. The storyline was compact and the leveling speed was fast, giving people a fresh feeling. The author's update speed was also guaranteed, making people look forward to the exciting developments in the later stages. This book brought a lot of things to watch, making people unable to stop. It was a Xianxia novel. It told the story of the protagonist who could refresh his golden finger once a month and continuously obtain strength through dual cultivation of soul and body. The author's writing level was recognized by Shimeng, who gave her a score of 8.6. All in all,"I Can Refreshed My Goldfinger Every Month" was a highly anticipated Xianxia novel. For readers who liked this genre, it was worth reading. 10."Master of All Realms Yue Buqun":"Master of All Realms Yue Buqun" is a very good new book. The author, Wastepaper Bridge, used Yue Buqun as the main character, telling the story of his disciples in various planes. This book continued the style of Wastepaper Bridge's variant Infinity Style, letting people feel Yue Buqun's dignity and wisdom as a gentleman sword. Although the character Yang Buhui appeared in the story, this small poison point did not affect the overall reading experience. This book had a very high evaluation and was rated as high-quality grain. It was worth reading. The author's identity as an old author also added a lot of credibility and stability to this book. In short, if you like the style and story of the Wastepaper Bridge, then 'Master of the Myriad Realms, Yue Buqun' is definitely a good book not to be missed. 11."Group Heavy Bombardment Kills Immortal Cultivators": A rare book that shows the integration of technology and immortal cultivation, depicting a world where everyone is like a dragon. Unfortunately, it was too young when it was discovered. "When Samsara Invasion": As the new book was really boring, I flipped through the old authors. Then, there was another book that I could read. 13."I'm Simulating the Myriad Worlds in the Immortal Fantasy": A Myriad World Record, Evolve the Myriad Worlds, and Become Your Own!

The Glazed Pure Land recruited 100,000 people from the Great Marsh, dug up mountains and rivers, and reclaimed 100 feet of land in search of the flood dragon's bones. The young man who died after swallowing the dragon scales opened his eyes again… "From the Research and Development of Muscle-bone Strengthening Scripture to the Other Shore": Step by step, the description of this cheat is very good, and the growth of various development topics makes sense. Moreover, the main character did not want to go against the world's trend. It was because of his master's kindness that he was unwilling to follow the martial arts academy established by the country. Here, the main character held a tutoring class and a training class. 15:"I'm in the Great Ming Dynasty's projection of the heavens during the recuperation of reiki!" In the unknown dimension, an unknown thing caused a slight collision between worlds, which led Wang Hwa to the Great Ming Dynasty in the Age of Chaos... His "apartment" had become her safe house and cheat… It was the thirty-first year of Jiajing when the Japanese pirates wreaked havoc in the Ming Dynasty… 16:"My Slow Infinite Journey": 75 points. Currently, it's a slow-moving type. The main character's ability is inclined towards the late stage. There might be a female lead. I feel that the emotional scene is a little abrupt. The current world of the Sword God's Domain wants to engage in an industrial revolution and then convinced Hayaba Akihiko. "Transmigrating to 99 Blue Stars at the Same Time": There are currently some types of transmigration, such as the Desolation Era Earth, the Devouring Earth, the Dragon Snake Earth, and the Book Desolation. Food, recommended. 18:"Returning from a low-magic world, first do artificial intelligence": recommendation index: I feel like the plot hasn't started yet. There was a finished work, although the name was Wu Jiechao, it still had integrity. 19:"Ten Cities, Nine Luminaries, Eight Extremities, Seven Elements, Six Divisions, Five Elders Fighting for Dao Fruit": The name is quite long and well written. Seeing that the plot was full now, there was little exaggeration. Ranking index: You can read these novels on Qidian Chinese Network.
