From the Start, I Have a Split Personality: My Sequence Is Copying

Drawn without warning into a battle between people with supernatural abilities, Yan Jin wakes up to find himself in a psychiatric hospital, with a second consciousness inside his mind! This bizarre consciousness doesn’t help the protagonist slaughter his way to the top. It’s always trying to take over his body instead. Relying on his cool-headed judgment, the protagonist crushes his enemies, copies their sequence abilities, and seizes their cultivation. You’re a deep-cover double agent? Bad luck. I’ll be taking over your line of work from now on! You’re the chosen one who can revive without limit? Sorry, I’ll take that overpowered ability off your hands!
