In the early morning, the sun shines through the curtains and shines on the edge of Xu Yan's bed.

He opened his eyes and jumped out of bed, feeling his whole body filled with strength.

According to the information I got when I signed up before, there is no fixed course for these students who have stepped into the ranks of martial artists, and there will be two big courses every day, and students who want to take it can participate independently.

After a simple wash, Xu Yan changed into clean clothes, and today he decided to soak in the library for a day to master some basic knowledge of the floating island.

The fragrant and smooth big meat bun was eaten into his stomach, and after eating twelve in a row, his stomach had a little sense of sufficiency, before the martial artist was world-class, he needed to consume a lot of ability through food to maintain his body, and the food in the martial arts academy was quite cheap, of course, the word cheap was only for Xu Yan.

The school library is located on the right side of the auditorium, and it takes twenty minutes to walk from Xu Yan's dormitory.

Along the way, many ordinary people who had not yet become martial artists hurried away, and there were not many warriors in a hurry, until they walked to the library, and Xu Yan saw definitely no more than ten.

After swiping the identity card and spending two credits, Xu Yan was able to watch it here for a day.

I slackly found a place by the window, took three or five books about the floating island, and read them slowly with a cup of hot tea.

"The Origin and Development of the Floating Island - Fear of Falling to the Ground."

"When the mutant beast appeared, the floating island appeared overnight above all the base cities that had built walls, and the surface humans thought it was an alien civilization invasion, until the European ascetic Snevaldo took the airship to the first landing on the floating island, these mysterious air islands were shown in front of human eyes, and the remnant governments of various countries occupied all the floating islands in the territory for the first time, which is also called a holy place by humans, and it is not as dangerous as the ground, except for the very rare attack of mutant birds, it can almost be regarded as a safe harbor for human beings."

"I don't know when the holy land of mankind has become closed, and the human beings on the surface no longer have the right to land on the island at will, and the floating island has begun to change greatly under the research of the remaining governments of various countries, human beings are good at creating, human beings are good at changing, less than fifty years have passed, and the peaceful floating islands have become fortresses of war......

"War fortress?" Seeing this, Xu Yan put down the book, and the speculation behind him seemed to him to have no basis, but why did he refuse to allow surface humans to land on the floating island at will, what did the government want to do?

After reading this book quickly, the doubts in my heart became more and more complicated, and after picking up another book, Xu Yan read it again.

"Floating Island Civilization - Tiles Between High-rise Buildings."

"The floating island is the weapon of human warfare, and the floating island is actually a secret weapon dropped by alien civilizations, why there is such a floating island in the sky above every walled base city, it is because, in ancient times, these walled base cities were the gathering place of human beings."

Compared with the fear of tiles falling to the ground, the statement of high-rise tiles is more thorough, in principle, Xu Yan believes in the second theory, if these floating islands are not developed by humans, then who built them.

The more I thought about it, the more messy it became, and my brain was muddy.

Xu Yan put down the book in his hand, slowly picked up the fragrant tea in front of him and took a sip.

"Whew...... Comfortable. ”

The heat wave passed through his throat and into his viscera, and the feeling of comfort made him want to scream.

Picking up the third book again and placing it on the table, Xu Yan slowly read it again.

"Why are the 100,000 mutants? - The tile fell to the ground. ”

"Are nuclear radiation and electromagnetic storms really the reason for the emergence of mutations at an early age? Why is it that some people are not affected by this? Is it true that there are different genes between people? Let's explore the difference between mutants and humans. ”

"Through the dissection of ten mutants and human corpses, it was found that the muscle level of mutants is more powerful, which shows that there are two or more routes in the direction of human evolution, and these mutants may be more suitable for survival in dangerous areas in the future."

"The common mutant body contains 12 percent fat, while the fat content of the average human reaches 45 percent, and under the clear changes of the four seasons, why these mutants are not killed by heat or freeze to death, it is because their muscle content is twice that of humans.

By dissecting the corpses of human warriors, we found that the evolution of human warriors is a sublimation from the outside in, and the same is the consumption of fat and the conversion of muscles into muscle, but compared with mutants, human beings have something called internal strength. ”

"Continuing to look at it, the mutants above the professional level have produced something similar to tuberculosis, which allows the mutants to also use the power of nature, does this mean that the process of evolution is different, and their ultimate goals are the same, then, the mutants are not our enemies, but the same race that has embarked on different evolutionary paths."

"Poof." Seeing this, Xu Yan felt very ridiculous. "Can the same clan fight each other like crazy? Can the same race eat the body of the same race? ”

When he remembered the experience of that beast tide, this book, which was regarded as a holy book by countless people, was casually discarded by him.

"Classmate, may I ask, is there anyone sitting here?"

Just as Xu Yan was very unhappy when he saw it, but the author was talking nonsense, and opposite him, a weak voice came into his ears.

Looking up, a woman with a delicate face and a long skirt with a wide body stood timidly opposite, and found that Xu Yan was looking at herself, with a hint of shyness on her face.

"Boom." There was a burst of explosion in his mind, male hormones swelled instantly, and this feeling of trembling all over his body appeared for the first time in Xu Yan, who was about to celebrate his nineteenth birthday, and there was an endless wonder in his heart: "Get her, have her, she is yours." ”

Suppressing the restlessness in his heart, Xu Yan's heart was beating at an accelerated pace, and he hurriedly lowered his head, and said in a slightly trembling tone: "No... No one, you sit. ”

The woman held two books in her arms, saw Xu Yan tidy up the books on the table, showed a smile like "thank you", gently put down the books, and lifted the hanging hair around her ears.

"If the heart is clear, the sky will not fall, if the heart is clear, the sky will not be shocked......"

Thinking of the messy things, Xu Yan couldn't calm down at all, pretending to look through Wawa's books, his eyes jumping from time to time, and secretly observing the girl in front of him.

The girl on the opposite side was looking at a book called "The Theory of Evolution of Martial Artists", Xu Yan's peek at her could sense it, but this was not the first time, Wu Mengdi had long been used to it.

Time passed quickly, in the silent library, Xu Yan gradually calmed down, breathed the fragrance of the other party's body in his nose, and the "Floating Island True Solution" in front of him A man and a woman sat opposite each other, looking extremely harmonious and peaceful.
