Spiritual Qi Revival: I Spent Ten Years Signing In in a Basement, and Now I'm Back

Ten years ago, spiritual qi revival began. Lu Zhuang hid in a basement to escape the monsters, and ended up obtaining a System. Ten years later, Lu Zhuang emerged from the basement. What kings and venerables? What demon fiends and strange creatures? I can suppress them all with one hand. What? You say you're a Demon King? Excellent... Demon Kings are the perfect creatures to put to work farming. Now get to my little world and submit to labor reeducation.
