Human Shackles

Luo Kai crawled back to the cell along the tunnel. At this time, the sky had turned slightly white. He took out the animal skin paper given by the old man. He did not know what kind of ink was used to draw crookedly small figures in strange postures on it. In Luo Kai's perception, they looked like It's some kind of gymnastics...well, more like yoga.

At this time, Luo Kai was exhausted and really had no energy to study, so he gathered the straw and fell asleep deeply with a belly full of questions.

After waking up, Luo Kai immediately studied the "physical skills" on the animal skin paper, which were actually some weird postures. After studying for a long time, he found that these postures had one thing in common, they were all trying their best to stretch the body. For example, the first In this movement, the toes are on the ground, and the body and arms are stretched upward as much as possible, until the whole body is stretched into an exaggerated long strip.

Luo Kai tried to do it, but found that his current physical condition could not do it at all. More than a year of lack of exercise made his body stiff like a robot. The pain in his muscles when he started doing it made him give up the plan. .

In the evening, Luo Kai entered the underground space full of bookshelves from the tunnel. The space was very large. After searching for a long time, he followed the light and saw Shuisou. He was writing and drawing in front of a huge desk, very focused, like Didn't notice Luo Kai's arrival.

Luo Kai walked forward carefully and noticed that the messy papers on the desk were covered with various geometric figures, and Shui Sou seemed to be doing arithmetic problems.

"I'm busy, please wait." Shui Sou said without raising his head.

Luo Kai silently retreated to a bookshelf and looked at the surrounding bookshelf. The characters in this world were very similar to Chinese characters, very concise, and there were many more symbols. He instinctively understood the meaning of these characters. Meaning, there are a wide variety of books on the bookshelves, covering physics, biology, engineering, mechanics... covering almost all known disciplines.

The name of a book caught Luo Kai's attention: "The Official History of the Era."

Luo Kai gently pulled out the book from the bookshelf and started to read it. The row of blood-red characters on the title page was shocking: "The stars fell, the magnetic poles reversed, the earth split, the earth fire rose, and the apocalypse came."

This is a history book that records that a huge disaster occurred in this world one day in the past. Many species were exterminated and human civilization was on the verge of extinction...

I don’t know how many years passed, but the external environment gradually improved, and finally the surviving humans began to rebuild civilization. However, the world has undergone earth-shaking changes, and many powerful and strange life forms have appeared. However, humans have lost what they had before the cataclysm. An important energy source, causing a huge gap in civilization...

At some point, Shui Sou had walked up to Luo Kai, looked at the books in his hand, and asked with some confusion: "Have you never been to school? What's so interesting about history books?"

Luo Kai didn't seem to hear Shuisou's question, his expression suddenly became dull, and a memory hidden deep in his heart came to his mind. It was his memory before his "death". At an altitude of 10,000 meters, a huge... A blue fireball fell from the sky, directly turning the passenger plane he was on into nothingness. At that moment, time and space seemed to be frozen forever, and he was not even aware of his own death...

Shui Sou saw something wrong with Luo Kai's expression, so he reached out and patted him on the shoulder: "Young man, are you okay?"

Luo Kai's face was pale, his forehead was covered with beads of sweat, and he shook his head: "I'm fine, uncle, can you lend me this book?"

"Okay, I won't teach you physical skills tonight. You can read a book instead." Shui Sou nodded in agreement and continued to study at his desk.

Luo Kai sat down on the desk and carefully read the "Official History of the Era".

"After the cataclysm, a large number of powerful "ferocious beasts" emerged. These ferocious beasts were extremely powerful, bloodthirsty and cruel, and could eat almost anything. The human living environment deteriorated rapidly... But the resilience of life is far beyond imagination. Survival The harsher the environment, the higher the evolutionary potential of species. Some human groups were forced to move to the ocean and evolved the miraculous underwater breathing ability. The best among them can even control the wind and rain! This group of humans living in the ocean call themselves For the "Sea Clan".

There are also some human beings who have struggled to survive in the desolate mountains. Due to the shortage of food, they use rocks and mineral deposits as nutrients and have evolved photosynthesis similar to plants. Gradually, their bodies have become larger and larger, and they have become infinitely powerful. , calling themselves the "Titans".

There are also some human groups that go underground to avoid being hunted by ferocious beasts on the ground. Year-round underground life makes them abandon the sunlight necessary for life, and instead embrace the dark abyss, becoming neither human nor ghost. Rumor has it that they have mastered Inspired by a terrifying dark corrosive force, they called themselves the Abyss Clan...

More humans still insist on resisting the invasion of ferocious beasts. Relying on the inheritance of human civilization before the cataclysm, firearms, gunpowder, and machines were quickly redeveloped. However, the ferocious beasts are unexpectedly powerful, and their bodies are covered with tough scales. Armor and fur, speed and strength are even more powerful, almost fearless of attacks from ordinary guns...

The advanced weapons that humans relied on for survival still could not gain the advantage in fighting ferocious beasts. Until another powerful biotechnology was developed. While fighting ferocious beasts, people discovered a way to plunder the powerful abilities of ferocious beasts. This method Originated from the "Human Genome Project", a grand scientific research project of mankind before the cataclysm, the emergence of genetic medicine finally allowed mankind to achieve a balance in the war with ferocious beasts.

Human territory began to expand, and the population also expanded rapidly. Countries, large and small, began to emerge, among which the nine major lord countries were the most powerful. External pressure eased, and internal conflicts began to emerge. Countries fought against each other endlessly to compete for population and resources. One of them was named Dong. The lords of the Yuan Kingdom gradually emerged. After decades of war, they conquered various countries, large and small, and forced the other eight major lords to surrender. The establishment of the Eastern Yuan Kingdom ended the century-long human civil war in the Eastern Continent... …

I don't know how long it took, Luo Kai breathed a long sigh of relief, stood up a little absent-mindedly, put the book back on the bookshelf, and said to Shui Sou who was still sitting at the desk: "Uncle...Uncle, I will go back first. Yes, tomorrow... I'll come find you again tomorrow."

Shui Sou glanced at him and waved slightly.

Back in the cell, the sky was still dark. Luo Kai leaned against the wall. The "Official History of the Era" he read today changed his limited understanding of the world. It was obviously a huge disaster that changed the world. Stars fell. It should be that the meteorite hit the earth's surface, which was also the source of the catastrophe. It was also probably the cause of his death in his previous life. Could it be that he did not travel through another world, but came to the earth a few years later?

After thinking for a long time, I could only find the answer by escaping from prison and seeing the outside world. Before I went to sleep, I suddenly remembered the water-repelling totem that Shui Sou had carved on himself. I stood up hurriedly, lifted up the black prison uniform, and borrowed Looking at his armpit under the moonlight, he saw that the wound had scabbed over. He endured the pain and peeled off the bloody scab. It was a strange dark red tattoo, like a small fish made up of a bunch of strange symbols. The tattoo was vividly drawn, and as the His skin trembled, and the little fish flicked its tail and swam as if it were alive.
