My Brother's Bodyguard in the Cultivation World

When a system glitch grants invincible powers to the wrong brother, Chen Yuan finds himself in an absurd predicament: he must personally cultivate his mediocre older brother into a cultivation genius. What starts as reluctant babysitting transforms into an addictive raising game as the overpowered younger brother turns the entire cultivation world into his personal playground. Together, this peculiar duo defies conventions—one nurturing and protecting, the other desperately trying to keep up—as they carve an unprecedented path through realms of immortals and monsters.
