Reborn in Demon Slayer: Using Technology to Slaughter Demons and Steamroll the Infinity Castle

Ling Yun, a top military engineer, is reborn in the world of Demon Slayer and binds himself to the Demon-Hunting Technology System! From the start, he uses a wisteria-pulse rifle to take down a Lower Rank demon in seconds, saves Maki, and gives Giyu Tomioka a taste of his own medicine! His mech stands against an Upper Rank, and his sunlight cannon obliterates Muzan. With technology, he rewrites every tragedy! The Hashira go from doubting him to worshipping him, while the Demon Slayer Corps becomes little more than a backdrop! He forms a high-tech demon-hunting squad, sends drones blasting through the Infinity Castle, and crushes the demon clan with mechanical gear! Reborn once more, Ling Yun uses modern technology to steamroll the demon world and show Muzan what it means to experience the ultimate thrill of a dimensionality-reducing attack!
