I Use Tortoise Shells to Collect Mountains and Seas

Civilization is not destroyed by natural disasters, but quietly "deteriorates" when no one is aware. The civil engineering professor transformed into the crazy city-building monster "Li Li" in the empty laboratory. The model couple abandoned each other on the eve of the disaster, but their souls were twisted into "birds of a feather" that could never coordinate. Yuan Cheng knew that this was no accident. Holding an ancient tortoise shell and copper coins that can deduce the secrets of heaven, he walks in this world that is gradually "animal-like". His mission is not to kill, but to "carry" - to take back the karma that burns the city, the jealousy that devours the heart, the greed that devours the sky... All the monsters and sins originating from the human heart. But every time he recovers a sinful beast, he becomes one step further away from mankind. What made him even more uneasy was that the mysterious old man who always guided him and recorded everything had a kind of deep waiting in his eyes. When the cracks on the tortoise shell were about to fill up, Yuan Cheng vaguely saw the end of his destiny. There, it seems, there is no salvation. But the... Beginning of everything.
