Apocalypse: I Have A Multiplier System - Chapter 501: Twin Brother?

Transmigrated into the world of Bleach, yet with no cheat, no special talents—just the meager edge of foresight. Higashi Shuuichi couldn't help but curse: “What the hell kind of advantage is that?!”So he made a swift, ruthless choice—cling tight to Aizen, survive his chaos first, worry about everything else later!

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?
