Lin Xuan, a top programmer, encountered code backlash while debugging an intelligent immortality system, and was reborn in a post-apocalyptic city where spiritual energy was revived. In this world, the ancient civilization of cultivating immortals coexists with the ruins of future technology, and people with superpowers and monsters run rampant. Holding the unfinished "God Machine Creation System" in hand, Lin Xuan discovered that his programming ability could actually rewrite the laws of reality - using codes to refine weapons, algorithms to deduce exercises, and construct a big data platform for cultivating immortals. While the major forces were still competing for ancient ruins, he had quietly built a global-covering Immortal Cultivation Internet, allowing cultivators in the entire apocalyptic city to become his "users." The plutocrats of the old era, the secluded immortal cultivating sects, and the gods coming from other worlds will all tremble in front of his system update log.
