Xu Qiu was transformed into cannon fodder in the world of immortality, and was bound to a system that makes a prodigal become stronger.

He wanted to go bankrupt after acquiring Barren Mountain, but in the blink of an eye his spiritual veins erupted and the land price soared a hundredfold. Even the poor girl who was saved casually was also a hidden fairy saint. Xu Qiu looked up to the sky and sighed: "I just want to be at peace with my family.
