Cheng Fei woke up to find he had transmigrated into the world of Demon Slayer and become the most useless Lower Rank demon in Muzan’s eyes: Cheng Fei Inoue!
“Kill a Hashira within a month, or I’ll kill you!”
With nowhere left to turn, Cheng Fei unexpectedly awakened a god-tier backstabber System!
As long as he switched sides, betrayed others, and sabotaged his teammates, Cheng Fei could keep getting stronger!
A stronger body! More bloodline powers! Greater martial skills! Even Breathing Styles! They were all available in the random prize pool.
“Boss Muzan, since you’ve shown me no mercy, don’t blame me for returning the favor!”
Muzan’s control over his underlings was downright monstrous. Even the slightest thought of rebellion would turn them into mush!
But with the System’s protection, Cheng Fei could keep his thoughts hidden.
As for how to go about it… he had plenty of options!
“Hey, guys! See that blond kid up ahead? He’s shaking like a leaf!”
“Don’t say I never do anything for you. I’ll drug him unconscious first, then you can have your way with him!”
“Ha ha ha! Go on! Kill him, or them!”
Overall it's okay, but it feels like it was written by Demon Slayer before he finished reading it.
