In his previous life, the boy was defrauded of his pension money by a so-called AI startup organization and died of desperation. Before he died, he vowed that if there was an afterlife, he would deal heavy blows to people and institutions that use high-tech fraud. Maybe God took pity on him and he was reborn before the college entrance examination.

He took the most vicious people who harmed him in his previous life from home to abroad, and killed them all, avenging his revenge in his previous life.
