Engineer Lu Li crosses into another world and becomes a mine slave awaiting slaughter. On the brink of death, he establishes a connection to Great Xia through a twin-fish artifact. With no fortuitous encounters or miraculous opportunities, the entire nation directs its resources toward cultivating Lu Li, prioritizing his journey onto the path of cultivation. Supercomputers help him refine cultivation techniques, while heavy industry mass-produces mechs and weapons to support his quest to establish his foundation and become an immortal ahead of everyone else. In another world, Lu Li mines spirit ores and studies artifact crafting, steadily advancing toward immortality while channeling knowledge and power back to Blue Star. This simultaneously ushers in an era of nationwide cultivation. Ultimately, he exposes the shocking secret that the cultivation world is actually a breeding ground for the demon race. Together with Great Xia, he builds a cross-dimensional civilization devoted to the pursuit of immortality.
