MTL - Global Evolution: I Have An Attribute Board - Chapter 12 first high school genius

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?

A little ruffian who fought recklessly without any morals and bottomline accidentally time-traveled to parallel space and became a Key Case Investigation Team agent. The huge change in identity had him creating chaos in the police station. However, a strange miracle system helped him repeatedly solve mysterious cases, turning him into an impudent ruffian detective!

Xu Xiuwen, who was battered and bruised, was reborn and found himself back at the farewell dinner after the college entrance examination. It was the year 2005. Facing the aggressive former love rival and the childhood sweetheart he once had a crush on, he decided to start a new life. After being reborn, he not only wants to recover the white moonlight that he missed in his previous life, but also builds his own business empire. Fame and fortune, career and love, he wants them all!

Unconditional obedience to him? Dream on! Regrettably, after marrying Tang Yuchen, An Ruo's daily thoughts were of escape, escape, and more escape! Someone grew furious, “You want to flee? The only way out is if you die, or I perish!” Fine, she chose death! Yet he laughed wickedly, “Woman, do you intend to kill the son in your womb?”
