Xu Ci was once a humble delivery rider and a single father who raised his daughter Xu Xingwan alone. In order to collect medical expenses for his seriously ill daughter, he delivered orders during the day and took odd jobs at night, living like a speck of dust in the cracks of the city. Until that night, he saw with his own eyes the truth about the powerful man forcing his wife to death. He was also designed to be the "culprit" and his daughter was almost taken away. When he was about to die, he awakened the "Book of All Evils" and could see the evil thoughts in people's hearts. He harvested the evil thoughts and turned them into demon seeds, which could be exchanged for strength, intelligence, life span, and even his destiny. From that day on, Xu Ci no longer believed that justice would come on its own. During the day, he was still a clumsy dad telling his daughter bedtime stories and learning to make children's meals; at night, he put on black clothes and followed his evil thoughts to find every damn person. Rich families, capital, gangsters, hypocrites, anyone who dares to touch his daughter will be sent into the abyss by his own hands. The world called him a devil, but Xu Ci only smiled faintly: If the world cannot tolerate a father protecting his daughter, then he will turn into a devil and create a bright future for his daughter.
