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?

It might sound extremely absurd and unbelievable, but it is the truth.” He said, his voice tinged with helplessness.“Hell, it is absurd.” She threw her hands up in the air exasperatedly. The seriousness in his eyes told her he wasn't at all joking or messing with her. He was damn serious.“Ugh. What shit am I involved in?” She asked frustratingly to no one in particular at the news she was still trying to wrap her head around.***Aristia Andrews had just come back home from work and prepared to go to sleep, when she was given a novel.Nothing strange about that though, huh?But just after she had completed the novel, she woke up to find herself tossed into a whole new world.
