Myriad Worlds Chat Group: I’m on a Killing Spree in the Apocalypse

Xu Yue transmigrates into a post-apocalyptic world, and thinks he is doomed to die in despair,

until, after his ninety-ninth transmigration and rebirth, he activates the Optimization and Modification System.

It can identify and fix flaws in anything, and gives tenfold returns.

He thinks the System is useless, until he joins a chat group...

Li Yunlong: "My wife was kidnapped, and the shells improved by Senior Xu actually made mushroom clouds! What a sight! Tenfold return on strategic thinking."
