Su Chen, the boss of the world's number one assassin organization, transmigrates into a book and becomes the terrible father of Su Nian. What's worse, his own daughter is the story's number one villain, destined to personally kill him in the future. To stay alive, he must first raise his daughter right! Su Chen is good at making money, protecting his daughter, and putting bad people in their place. But all his earnings must be handed over, and even buying snacks requires an application. From then on, he has only thirty yuan a day in pocket money. That is, until a beautiful woman who looks remarkably like Su Nian shows up at his door.
