My Dantian Shattered, and I Bound a Random System

[Transmigration], [Reborn], [Mortal's Journey], [Cultivation]

The premise: His dantian was shattered, and he was tossed into a mass grave to die. The good news: he bound himself to a System. The bad news: other people's Systems give them divine arts and divine weapons, while his first skill is called “Getting Food Stuck in Your Teeth Every Day.” In this ruthless world of Cultivation, a cripple with no dantian crawls out of the mud with the help of a ridiculous random System. He thinks the worst that can happen is spending his whole life as a mortal, until he discovers that the things he draws at random are prying open this world's deepest secrets. And the stone on his chest is starting to heat up.

Worldbuilding: A world dominated by Cultivation sects. The sects control spirit-stone mines, inheritances of cultivation techniques, and cultivation resources, while mortals occupy the very bottom of the sect hierarchy. But beyond the known world, something far greater exists: an ancient barrier called the “Iron Curtain” cuts this land off from the outside.
