In the tenth year after the spiritual energy was revived, the old world was crushed by the craze of spiritual beasts. Lin Cheng knelt at the door of the Beast Control High School and dug out the discarded spirit beast molts from the trash. People passing by spat at him: "Disaster, you don't even have the lowest fur ball beast, do you deserve to live?" He was used to it. In this city, people without spiritual beasts are useless. Until late at night, he found a deformed cub deep in the garbage mountain - covered in ulcers and shivering. Everyone said it was an ominous thing and must be burned to death. But Lin Cheng took off his coat and wrapped it around him: "Don't be afraid, I'm a throwaway thing just like you." The next day, the city alarm sounded. Official announcement: Lin Cheng colluded with the beasts and caused a wave of beasts, killing seventeen people. The evidence was conclusive and the whole world believed it. Only Lin Cheng knew that he didn't leave the garbage dump at all that night. He chose death. When the dagger pierces the heart, the world begins to turn upside down. Lin Cheng opened his eyes and found that he was back to yesterday. But his best friend Su Xiaotang looked at him blankly: "Who are you?" Death will randomly erase a bond. Lin Cheng smiled. It doesn't matter, he can die many times. Every time, he takes a step closer to the truth - even if everyone forgets him in the end, he still wants to let the cub live. Does the city believe lies? Then let lies become his sharpest beast.
