Immortals as My Servants, Emperors as My Slaves. I’m Just a Mortal, Got a Problem with That?

【Fantasy with a wild premise + delusions of grandeur + hidden master + System + transmigration】 Li Xuan transmigrates to a fantasy world. Though he has mastered every skill, he can’t cultivate, so he settles down as an ordinary man in a small mountain village. But he never expected that the girl he saved would turn out to be an empress who rules the world. The fox he picked up would turn out to be a nine-tailed celestial fox. Even the dog guarding the thatched cottage where he lives is a Heaven-Swallowing Divine Beast, while the chicken in his pot and the fish he steams are a True Phoenix and a True Dragon… As time passes, after countless ages, he shatters the void with one punch. Only then does he realize why the myriad races of the heavens, the Immortal Kings, and the Demon Emperors all revere him as a sage… Immortals as servants, emperors as slaves. I’m just a mortal. Got a problem with that?!
