Xu Ci, a scheming and cold-blooded top killer, was betrayed by his most trusted partner in his last mission. He was shot several times and fell into the deep sea. Before he died, the evil thoughts in his heart completely exploded, and he turned into a demon, and his soul fell into the abyss of the demonic world.
Ten years later, Xu Ci, the most feared Shura King in the demon world, returned to the world in search of a lost artifact. However, what he never expected was that his demonic energy would accidentally activate the mysterious seal in a three-year-old girl. This child named Nian Nian has been clinging to him since then, calling him "Daddy" every time he opens his mouth.
Xu Ci originally wanted to kill someone and silence him, but found that Niannian's physique could suppress the backlash of the demonic energy in his body. In order to survive, the Shura King who once massacred the city and exterminated the clan was forced to start a career of raising children.
Kindergarten parent-teacher meetings, late-night coaxing, cooking and laundry... When a group of reckless villains came to the door, Niannian hid behind Xu Ci and said in a sweet voice: "Dad, they are so fierce." Xu Ci wiped the water on his hands, his magic eyes were scarlet: "Good boy, close your eyes and count to ten."
When the indifferent devil daddy finally cared about the world, his former enemy extended his claws to Nian Nian. With one thought of becoming a demon and another thought of protecting the cub, Xu Ci wants everyone to know - anyone who touches my daughter will be punished by the nine tribes.
