Xu Nian, the "gentle hunter" on the S-class wanted list, codenamed "Milk Dog", is a madman who looks harmless to humans and animals when he smiles, and can send people on their way just by turning around. Betrayed by the top management of the organization, he was poisoned and fell into a busy city. He was regarded as an amnesiac vagrant and was taken back to a third-rate university to work as a security guard. The feared "living king of hell" in the past is now pointed at by bully students and called "watchdog". The scumbag school bully insulted the beauty of the college in public. Xu Nian wanted to smoke a cigarette to endure it, but found that there was only a lollipop left in his pocket. He licked the candy and smiled, a harmless smile: "You touch her, and I will make your father kneel down to redeem you tomorrow." No one knew that this useless security guard who held lollipops all day long had top-secret information in his body that could subvert the global dark web.
