Demon Slayer: Uncle Jiu Helps Me Thrash Muzan!

[No heroine, no breaking up couples, no System, Uncle Jiu, tormenting ghosts, transformation, crossover, and a talkative protagonist] Chen Can, who harbors a deep grudge against Muzan Kibutsuji, transmigrates into the world of Demon Slayer as a stone. After being nurtured for a thousand years through the efforts of Kong Hai and Seimei, he finally takes human form and happens to meet Uncle Jiu, who also transmigrated to this world. Chen Can soon discovers that this all-in-one version of Uncle Jiu is absurdly powerful! From the start, he brutally beats Muzan, giving him a new psychological scar, second only to the one left by Yoriichi Tsugikuni, the strongest fighter in Demon Slayer. And so begins a game of hunting down Muzan and beating him senseless! The story takes place several decades before the main story begins! At the time, active on the demon-hunting battlefield are the young Sakonji Urokodaki, Tanjiro Kamado’s master and former Water Hashira, and Jigoro Kuwajima, Zenitsu Agatsuma’s master and former Thunder Hashira, along with Demon Slayer Corps members who have close ties to the future Hashira! As for the protagonist... After teaming up with Uncle Jiu to take Muzan down in an instant and beat him senseless from the start, he unexpectedly discovers an even more powerful force lurking behind Muzan. To unmask the mastermind behind the tragedy that wiped out the Hashira, a decades-long standoff begins! P.S. Like the protagonist, the author is a die-hard Uncle Jiu fan! If that’s not your thing, feel free to move along!
