Beheading the King of Hell: I Slay Demons at Bureau 749

[Decisive and ruthless] [Overwhelming everyone] [Absolutely no saintly heroine] [All demons deserve to die] [No female lead] Shu Xiao had been quietly working as a security guard in the Muye residential complex. But one night, a blond punk tried to assault a woman in thigh-high stockings. Shu Xiao took the punk down in no time, only for the guy to start radiating black mist and stop acting human. That only got Shu Xiao more excited. He grabbed the long knife hidden under his bed and took the guy out with one slash. His golden finger, the Demon-Hunting Compendium, awakened instantly, granting Shu Xiao extraordinary powers. Every demon he hunts awakens a new ability, with no limit in sight. [Hunt the Venom Demon, gain the power of shadow] [Hunt the Flame Demon, gain hellfire] [Hunt the Greed Demon, gain fusion enchantment] Shu Xiao: “Cut the weeds at the roots before they grow back. There's nothing one slash can't solve. If there is, use two.” 《It was too weak. I killed it instantly without even noticing.》 《I thought it was a low-level demon.》 《Take it up with my demon-hunting skills!》 《We're all doing our best to survive.》 I did my best, so how are you still alive?
