Luo Kai crawled back to his cell along the tunnel. By this time, the sky had already turned slightly white. He took out the animal skin paper that the old man had given him. It was covered with crooked drawings of little people in strange postures using some unknown ink. In Luo Kai's mind, it looked like some kind of gymnastics … Well, it looked more like yoga.
By then, Luo Kai was already exhausted. He had no energy to study it. With a stomach full of questions, he gathered the straw and fell asleep.
After waking up, Luo Kai immediately studied the "body art" on the animal parchment. It was just some strange postures. After studying it for a long time, he found that all the postures had one thing in common. They were all about stretching the body. For example, the first movement was to put the toes on the ground and stretch the body and arms as far as possible. The whole person had to be stretched into an exaggerated long bar.
Luo Kai tried to do it, but he found that with his current physical condition, he could not do it. The lack of exercise for more than a year had made his body as stiff as a robot. When he started, the sharp pain in his muscles made him give up on the idea of practicing.
At night, Luo Kai entered the underground space filled with bookshelves through the tunnel. The space was very spacious. After searching for a long time, he found Shui Sou. He was writing and drawing in front of a large desk. He was very focused, as if he did not notice Luo Kai's arrival.
Luo Kai carefully walked forward. He noticed that the messy papers on the desk were filled with various geometric figures. Shui Sou seemed to be doing arithmetic.
"I'm busy. Wait here," Shui Sou said without raising his head.
Luo Kai silently retreated to a bookshelf and looked at the surrounding bookshelves. The words in this world were very similar to Chinese characters. They were very concise, and at the same time, there were many more symbols. He instinctively understood the meaning of these words. There were many kinds of books on the bookshelves, including physics, biology, engineering, machinery … They almost covered all known subjects.
The name of a book caught Luo Kai's attention. "The History of the New Era."
Luo Kai gently pulled the book out from the bookshelf and flipped through it. On the title page, there was a row of blood-red words that were somewhat shocking. "Stars fall, magnetic poles reverse, the earth splits, earth fires rise, and the apocalypse arrives."
This was a history book. It recorded that one day in the past, a huge catastrophe happened in this world. Many species were tragically wiped out, and human civilization was on the verge of extinction.
After many years, the external environment gradually improved. Finally, some surviving human beings started to rebuild their civilization. However, this world had undergone earth-shaking changes. Many powerful and weird life forms had appeared. However, human beings had lost an important source of energy before the Catastrophe, causing a huge gap in their civilization...
Unknowingly, Shui Sou had walked to Luo Kai's side. He looked at the book in his hand and asked with doubt, "Have you never been to school?
What's so interesting about history books? "
Luo Kai did not seem to hear Shui Sou's question. His expression suddenly became dull. A memory hidden in the depths of his soul surged to his mind. It was the memory before his "death". At ten thousand meters in the sky, a huge blue fireball fell from the sky and directly burned the passenger plane he was on into nothingness. At that moment, time and space seemed to be frozen forever. He did not even realize that he had died.
Shui Sou saw that Luo Kai's expression was not right. He reached out and patted his shoulder. "Young man, are you alright?"
Luo Kai's face was pale. His forehead was covered with fine sweat. He shook his head. "I'm fine. Sir, can you lend me this book?"
"Sure. Then I won't teach you any physical skills tonight. You read the book." Shui Sou nodded in agreement and returned to his desk to study.
Luo Kai leaned against the desk and sat down. He carefully read the "History of The New Age".
"After the catastrophe, a large number of powerful" ferocious beasts "emerged. These ferocious beasts were extremely powerful and bloodthirsty. They ate almost everything. The living environment of humans deteriorated rapidly. However, the resilience of life was beyond imagination. The worse the living environment, the higher the evolutionary potential of the species. A part of the human race was forced to move to the ocean and evolved the magical ability to breathe underwater. The best of them could even summon the wind and the rain!
This group of humans living in the ocean called themselves the "Sea Race".
There was also a group of humans who struggled to survive in the barren mountains. Under the shortage of food, they used the mountain rocks and minerals as nutrients and evolved the photosynthesis of plants. Gradually, their bodies grew larger and larger, and they became extremely strong. They called themselves the "Titan Race".
There was also a group of humans who moved underground to avoid being hunted by the ferocious beasts on the surface. Living underground for many years made them abandon the sunlight that was essential to life and embrace the dark abyss. They became neither human nor ghost. It was said that they had mastered a terrible dark corrosive power. They called themselves the "Abyss Race".
More humans still persisted in resisting the invasion of the ferocious beasts. Relying on the inheritance of human civilization before the catastrophe, they rapidly developed firearms, gunpowder, and machines. However, the ferocious beasts were unexpectedly powerful. Their bodies were covered with tough scales and fur. Their speed and strength were incomparable. They were almost unafraid of the attack of ordinary guns and cannons.
The advanced weapons that humans relied on for survival were still unable to gain an advantage in the battle against the ferocious beasts until another powerful biotechnology was developed. In the battle against the ferocious beasts, humans discovered a way to rob the ferocious beasts of their powerful abilities. This method originated from a magnificent scientific research project before the catastrophe, the "Human Genome Project". The appearance of the gene medicine finally allowed humans to achieve a balance in the war against the ferocious beasts.
Humans began to expand their territory and their population rapidly. Large and small countries began to emerge. Among them, the nine suzerains were the most powerful. As the external pressure was reduced, internal conflicts began to emerge. Countries fought against each other endlessly for population and resources. One of the suzerains, the Eastern Empire, gradually emerged. After decades of war, it conquered various countries, large and small, and forced the other eight suzerains to submit to it. The establishment of Higashimogami Province ended the century-long civil war in the Eastern Continent.
After an unknown period of time, Luo Kai heaved a long sigh of relief. He stood up absent-mindedly, put the book back on the bookshelf, and said to Shui Sou, who was still sitting at the desk, "Master... Master, I'll go back first. I'll come to you tomorrow."
Shui Sou glanced at him and gently waved his hand.
Back in the cell, the sky was still dark. Luo Kai leaned against the corner of the wall. The "History of the New Age" that he had read today had changed his limited understanding of this world. Obviously, a great catastrophe had changed this world. The falling stars should be referring to a meteorite hitting the earth, which was also the source of the catastrophe. It was also very likely that it was the cause of his death in his previous life. Could it be that he did not travel to another world, but came to the earth many years later?
After thinking for a long time, he decided that he could only find the answer by escaping from the prison and going to the outside world. Before falling asleep, he suddenly remembered the water-repelling totem that Shui Sou had carved on his body. He hurriedly stood up, lifted his black prison uniform, and looked at his armpit under the moonlight. The wound had already scabbed. He endured the pain and peeled off the scab. It was a strange dark red tattoo, which looked like a small fish formed by a bunch of strange symbols. The tattoo was vivid. As his skin trembled, the small fish swam as if it was alive.
