Uchiha's God of Muscle - Chapter 3: spy

A man who was once called the world’s strongest agent ended up becoming a teacher after his retirement, to train a new generation of agents. After many years of training his disciples, he was killed at the age of 60 by a secret organization’s ruse and was reincarnated in another world with his memories intact. Though he was surprised by the existence of magic and the strange species in that world, he quickly adapted to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his rigorous discipline, in order to reach his goal: Resume his career as a teacher which he left halfway through in his previous life. This is the story of a man, who, based on the memories and the experiences of his previous life, became a teacher who travels through the world with his students.

Chu Mu Yun relied on his story of 《Demon Realm》 to become a one-hit wonder in JJWXC, but the him who had written seven mental cases to abuse seven mental cases to death would never have expected that he himself would transmigrate into this shitty novel!
What the hell is this system on the bracelet?
And what the hell is this either propose to seven men, or suffer the taste of a tragic death experience under the hands of these seven people?
I just wanted to write a novel to satisfy my bad interests, who would actually want to get tangled up with a bunch of mad dog sad*st crazies?
