Lu Li, a college student in the 21st century, traveled through the realm of immortality to become a waste of five spiritual roots. He was trapped in the Qingchi Demon Sect mine to survive. He accidentally contacted the Xia State Special Administration Bureau with the help of a fish-shaped jade pendant. Backed by the technology and resources of his motherland, he counterattacked with modern weapons and industrial refining tools, and also sent back immortality cultivation resources to help Xia Kingdom start the cultivation of immortality for all people. Lu Li revealed that the Qingchi Sect was the "ration farm" of the great demon Youchan, and teamed up with the Xia Kingdom to modify Youchan's memory to subdue it. He also prepared for the battle to destroy the mansion a hundred years later, using the power of the Xia Kingdom to set off a human counterattack in the world of immortality.
