Invincible Domain: One Centimeter

Mortal Lu Changshen transmigrates to a cultivation world governed by the law of the jungle, only to find himself a useless genius with a leaking dantian, hiding away in the ninth peak of Taiyi Holy Land. In a moment of crisis, he binds to the Invincible Domain System: within a ten-meter radius centered on his small courtyard, his words become law and he is absolutely invincible; however, stepping outside the white line reverts him to a powerless mortal. Even more frustrating, the domain expands by only one centimeter each day.
