When Death Has Rules

In this world, ghosts cannot be killed. They can only be understood. Every supernatural being follows a rule. Break the rule, and death will come. Discover the rule, and you may survive. Yan Wang was just an ordinary person. He was not powerful. He had no special abilities. When the first ghost appeared, everyone around him fell into panic and died one by one. But Yan Wang noticed something others ignored. The ghost was not killing randomly. It was following a rule. Through fear, courage, and careful reasoning, he found the first way humans could fight against the unknown. From that night onward, Yan Wang stepped into a hidden world where ghosts ruled by laws, and survival belonged only to those who could understand them. One day, the world would know why his name was Yan Wang. Because the person who controls the rules of death... Becomes the king of the dead.
