I Was The Demon Cult’s Rabid Dog
Born to kill. Raised in chains. Branded by the Demonic Cult.
Mae-Bi was the weakest of the Blood Blade assassins — a disposable dog bred for slaughter, shackled by the cursed centipede in his heart. Obey or die. Betray and burn.
Until they ordered him to assassinate a man no one should’ve touched.
He failed. He died. And the world should’ve forgotten him.
But fate didn’t.
Granted a second life by the very man he was sent to kill, Mae-Bi awakens in his eighteen-year-old body — with a deadly system in his head and a lifetime of assassin experience in his veins.
This time, he’s not just a pawn.
He’ll master the blade they used to control him. He’ll steal every forbidden technique. And he’ll climb the cult’s ranks — not to serve it…
…but to gut it from the inside.
Hi everyone! Before you begin reading, I wanted to share a little about this story and answer some common questions upfront. This novel draws inspiration from elements I love Nano Machine (system-based progression), while blending in my own original twists. At its core, it’s a revenge-driven tale with strategic action and dark undertones. To clarify upfront: No harem– Focus remains on the core narrative. No romance subplots A calculating MC– The protagonist thinks tactically before acting. Violence/gore is present– Reflecting the harsh Murim world. I hope you enjoy the story! If you have any other questions, feel free to ask.
