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!

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?
