Demon Sect Survival: I Trade My Life to Become the Ultimate Overlord

Transmigrated into a demon sect with a cheat system and a death sentence—seven days to live. The twist? Every power-up drains lifespan, but devouring other demons extends it. Bi Yang must navigate a blood-soaked world where cultivation costs life itself, and his only salvation lies in slaughtering the very demons who raised him. When the sect's twisted rules turn survival into a deadly game, he'll burn through lives—his own and others'—to claw his way to the top. In a realm where one day equals one night, power is the only currency that matters.
