Author: What's Wrong? Deep Sea Ember, Author: Yuantong Chapter 19: Cultivation in the Chaotic World of Demonic Martial Arts, Author: Wenplagiarism 20:" Who told him to cultivate!" Author: The Whitest Crow The following is a detailed introduction of these novels: 1." Book of Troubled Times ": Holding a sword, drinking in Jianghu, slender waist and light palm. The young man carried a long saber on his shoulder and hung wine on his waist. He strode forward, but the Jianghu in his heart was vaguely difficult to see. Turning a page in the book of troubled times, it would rain for decades in the Jianghu. Suddenly looking back, the world has been split into pieces. 2." Spirit Realm Traveler ": The style of the newspaper seller is very obvious. After all, you can learn a lot of idioms from books. After reading his book, I can no longer look directly at the traditional culture of my country. Other than updating it a little, it's a little bit sloppy, and there are a lot of typos, there's nothing wrong with it. 3." Tang People's Table ": Telling the book has been written. Contact list owner can get it. [The review is too strict. The single owner really has no choice but to try to modify it back and forth.] [Everyone can leave a message on the book list or contact the fan group of the novel.] 4." King of the Familiar ": Familiar, Beast Speaker, Familiar Awakening The quality of Er Quan's new book is still guaranteed. I think the current twelve chapters are okay. This world view is the early stages of the descent of familiars. The male lead has the ability to communicate with all things and a antler pendant with healing abilities. He would take care of it first. There were still too few at the moment. 5: Fairy, Please Listen to My Explanation: Multiple Female Lead 3+ It had to be said that the female lead's standard was not bad. She was about seven out of ten, but the story was really good. It could be said to be top-grade among similar works. " Sword Snow Stride " was too " literary " for me. I think this one can be used as a replacement. Compared to some books that placed too much emphasis on whether they were trash or not, this method of directly avoiding this question had a different taste. It also saved the readers from having to question themselves morally. 6： National Forensics: The author's previous novel, The Great Doctor Ling, was written about forensic science. It was quite good. I liked the protagonist of this author the most. There would be a cheat, but the protagonist was not the kind of person who blindly used a cheat. There would be many highlights. In other novels, the cheat made me feel that I could do it myself. However, the charm of the protagonist in his novels even made me, a reader who knew that he had a cheat, like him. I always thought that if I were a passerby girl in the novel, I would probably like the protagonist too. Hahaha. I recommend everyone to fatten up together 7:" Heroine, Wait ":[Status] Hot Series🔥🔥🔥 < Synoptic > The orphan of King Tianlang, the empress's favorite concubine, King Jing's son-in-law, the lover of a traitor, the enemy of a heroine, the wandering swordsman of Jianghu, the master of both swords and spears…The Night Terror Hall promised to go to the capital city from the border to meet the appointment. From then on, it stirred up the Jianghu temple and created a new chapter… < Remarks > Young Master Guan Guan's new masterpiece. He is familiar with outstanding talent and extraordinary family background. He wanders among many women of high status and power. He eats soft food and eats hard. At the same time, his combat description is also one of the best in the warm daily life. Quickly read it! 8." Mantang Colorful ":" Mantang Colorful " was an outstanding literary work of the Tang Dynasty. The author described the magnificent Tang Dynasty vividly and gorgeously, making people feel as if they were in that era of blooming flowers. The story was set in the fifth year of Tianbao. It described the prosperous scene that an ordinary person saw when he opened his eyes. At the same time, it also revealed the endless struggle for power within the imperial court and the precarious situation of the country. In this perilous era, the protagonist was determined to ensure that the Great Tang would not lose its splendor. The author's writing style and story were very strong, making people unable to extricate themselves. Whether it was the description of the history of the Tang Dynasty or the shaping of the characters, they were all very accurate. In short, this was a stunning work of the Tang Dynasty and was worth reading. 9." Hidden Dead Corner ":" Hidden Dead Corner " is a fascinating novel. The author, Get Away, has attracted many readers with his unique style and exquisite writing. The opening of the book showed the exciting scene of the protagonist starting the game, which filled people with anticipation. The author skillfully integrated sci-fi and horror elements into it, giving people a different reading experience. The protagonist's cheat was a series of warframes that could be upgraded. The author's description was exquisite and vivid, making people feel as if they were in a mecha battlefield. The author's pen was amazing, and the supporting characters 'IQ was just right, convincing. Even though the little fairy character at the beginning was a little disgusting, the description of the mech made many people feel awe for him. Although the subsequent plot remained to be seen, overall," The Hidden Dead Corner " was a good book that was worth reading. " Final Divine Duty ": The cosmic mecha was as strong as a dragon, and the gods and devils in the abyss whispered and roared. In this era where new and old techniques, technology and divine power collided, Lu Yuan brought along an attribute panel that allowed him to change classes indefinitely and stumbled down. "Class [Martial Arts Grandmaster]+ Material [Abyss Nine-Headed Dragon Heart], can be upgraded to [Dark Dragon Sect]..." Lu Yuan looked at his hands that were gradually covered with black scales. The black hair on his back danced wildly without any wind. His dark red eyes stared at the human-shaped mechanical body that streaked across the night sky like a meteor. He smiled and muttered to himself in a low voice," Now..." I should be able to tear apart a Mech with my bare hands…" 11:" Beyond Time ": I haven't seen the alliance yet, let's raise it This Game Is Too Real: Status: New [Short comment: Chen Xing became popular after the apocalypse, so this book should be back to square one.] The content was about the behind-the-scenes construction of the wasteland. The current level was getting better, and the plot was getting more and more creative as the construction started. The progress was relatively slow, but the unique desolate and barbaric taste of the apocalyptic wasteland was indeed felt. However, the problem was that the layout was too vast, and there were too many characters to focus on. As a result, most of the time, the book felt very scattered and watery. This might be a common problem of the behind-the-scenes style, and it was difficult to achieve perfection. Rating: 13:" Red Heart Sky Patrol ": A new god ascended the throne. This book will definitely become a god! Excellent! I strongly recommend you to enter the pit. Take your time and read the third volume patiently. I guarantee you won't be disappointed. ----------------- 2021.2.20 The first evaluation, the second. It's a good book recommended after reading the second chapter. The name is a little old-fashioned. ----------------- 2021.3.19 The second evaluation, a. After reading the first volume, he strongly recommended it again. It was an absolute immortal herb. His writing style was first-class, and his ability to create characters was at the peak. He could clearly remember the names and personalities of almost every character who appeared. The disadvantages were that part of the plot was a little old-fashioned, the protagonist's presence was weak, and the character's rate of death was a little high… ----------------- 2021.3.26 Three comments, first up. After reading the third volume, all the flaws in the early stages were swept away. He could be sure that as long as the ending was not bad and there was no eunuch, it would definitely be a divine work. ----------------- 2021.4.15 Four comments, first class. He had caught up with the latest progress, the Yellow River Meeting Plot. Let's not talk about the advantages, let's talk about the disadvantages. First, although the background was grand, it lacked novelty and the plot was a little old-fashioned. Fortunately, the author's writing was strong enough to write the old-fashioned plot. Second, compared to the many supporting characters with distinct personalities, the protagonist's creation was not outstanding enough. He was clearly a peerless genius. However, it didn't always make people feel that it was brilliant. It could also be because the supporting characters were too successful and took away too much of the excitement. Thirdly, the plot development was slow. There were countless holes buried and new plots kept being created. He only hoped that the author had enough professional ethics and didn't let the ending be a mess or a eunuch. He would fill in all the holes dug in the beginning. In short, it was an excellent book. Moreover, it had a large amount of content. It was recommended to enter the pit. ------------------ 2021.5.4 Five comments, no A true divine work would be considered a god-level work, and the first evaluation would be above armor. The author's pen strength was too strong, and it had the style of ancient times. Writing a web novel was a blow to his reputation. As long as it didn't end badly, there was no reason for it not to become a masterpiece. ------------------ 2021.12.29 Recently, the quality of the novel had declined. The author wanted to express too many things and was overly concerned about the readers 'opinions of the characters. It seemed like they had reached a bottleneck in the transition from traditional novel authors to web novel authors. Let's watch for a while. 14." Ring of Fate ": Finally, the time has come. Squid's new work is back as scheduled. It's also the continuation of my favorite " Lord of the Mysteries." Strongly recommended! 15:" The Great Ming State Preceptor " The author started from a unique perspective, writing from the direction of the historical trend. The author used the dialogue between the past and the present as a starting point. Through the blending and collision of ancient and modern thoughts, he constructed the characters. They were vivid, full, and full of depth, giving people enlightenment. [Reading Progress] He had the auto-feed on, but he didn't keep reading. [Author's impression] The author's professionalism was high, and he had a lot of knowledge. He had a wide range of knowledge, and his writing was as smooth as flowing water. It was amazing! To me, the excitement before the release of the main character is a little monotonous. I look forward to the author's wonderful description after the main character is released from prison! As a snake hunter, Xu Ying had always been honest and diligent until this day when he caught a different snake... On the first day of the third month, incense was burning everywhere in the Divine Land. The statues that protected the villages, towns, cities, and counties woke up one after another to enjoy the sacrifices of the people. However, from that day onwards, the world was in chaos. 17:" Who's Going to Fall in Love After Being Reborn ": The writing is not bad, the plot is exciting! I'd like to call it "I really didn't want to be a sea king after being reborn as a bootlicker." Description: Struggle until you can't afford a house at the age of thirty-eight. If you want to get married, you have to pay 300,000 yuan as a betrothal gift. You have to live frugally for most of your life. Who earned the money? Jiang Qin, who had been reborn at the age of 18 with countless grievances, opened his eyes and the only thought was to start a business and make money. The first step was to snatch back the love letter, turn it over, and write three lines under the school belle's shocked eyes: No matter what, he couldn't work. If he could get rich, he would get rich. Money can be earned again, but conscience can be earned even more! The livestock of the society will never be slaves! As for love? Even dogs wouldn't talk about that! " Deep Sea Ember ": The Real Duncan: Friendly, Passionate, Longing for Ordinary Delicious Food Duncan in the eyes of the world: the ghost captain of the Lost Homes, the 005-vision that destroyed the world, and the misfortune of losing San at a glance. The big-eyed Xyrin sci-fi style + antithesis, a different kind of joy 19." Gou in the Demonic Martial World to Cultivate Immortals ": A new book of plagiarism. His book might not be particularly amazing, but the quality was definitely good. Moreover, he avoided poison points +max. "Who told him to cultivate!" "Who told him to cultivate!" It was a Xianxia classical Xianxia novel. The author, The Whitest Crow, started the story with smooth writing and rich memes. The story began with the test to enter the academy.

He integrated the story into the story, making the entire cultivation system seem natural and not abrupt.

The difficulty of landing humans on Mars
Mankind's landing on Mars faced many difficulties: 1. ** Distance **: The distance between Earth and Mars varies greatly. The nearest distance is about 55 million kilometers, and the farthest distance is more than 400 million kilometers. This makes the flight time may be as long as several months or even years. Astronauts have to face challenges such as prolonged loneliness, psychological pressure, and cosmic radiation during the flight. This is a great test for the astronauts 'psychology and psychology, and it is also the ultimate challenge for aerospace technology. 2. ** Harsh weather conditions **: Mars 'atmosphere was thin, and the air pressure was only 1% of Earth's. The temperature was extremely low, and it often suffered from natural disasters such as storms and sandstorms. There were also huge sandstorms and canyons on the surface of Mars. These harsh environmental conditions threatened the lives of astronauts and increased the difficulty and complexity of Mars exploration. 3. "Scarcity of Resources": Compared to Earth, Mars 'oxygen, water, and other resources were extremely limited. Astronauts needed to carry a large number of necessities and scientific research equipment on the surface of Mars. At the same time, they had to learn how to use Mars' limited resources (such as extracting water and ice) to sustain life and scientific research activities. This required astronauts to have excellent survival skills and scientists to constantly explore. 4. There were many technical problems, such as how to design a rover that could land stably on the surface of Mars, how to provide enough oxygen and food for astronauts, how to deal with radiation problems on the surface of Mars, etc. These technical problems required scientists to continuously research and experiment, investing a lot of manpower, material resources, and financial resources. 5. ** Huge cost **: From research and development to launch, to follow-up operation and maintenance and scientific research activities, a large amount of capital investment was required. How to balance the relationship between capital investment and scientific research results, and to achieve the greatest scientific research value and social benefits within a limited budget was a realistic problem that needed to be faced. 6. ** Difficult landing **: Although the Martian atmosphere is thin, it is enough to affect landing. The atmospheric density fluctuates greatly. Without manual control, soft landing is very difficult and equipment is easy to damage. Moreover, it required "warm sunny days," windless, quiet weather, and careful selection of landing sites without boulders, potholes, cracks, etc. Although the descending vehicle was equipped with sensors to monitor external conditions, sudden impacts or changes in atmospheric pressure could cause irreparable damage. At the same time, the gravity on Mars was smaller than on Earth, and the atmospheric density was lower. All processes controlled by electronic devices on the module could malfunction or malfunction at any time. The novel "Hundred Years of Spaceship" is equally exciting.
