Lu Xian, a logistics disciple of the Qingyun Sect, cannot wield a flying sword or refine pills. His usual duties are simply repairing the sect's security gates, restoring formations, and maintaining flying swords. But when an Immortal Venerable gets locked up, a pill furnace explodes, the immortal cranes go on strike, and the protective grand formation malfunctions, one bizarre accident after another strikes the sect. Astonishingly, he is the only one who can fix them all. As mysterious demonic energy seeps into the sect, Lu Xian joins forces with Shen Shuang, the senior sister of Sword Peak, to investigate the truth. From an overlooked junior logistics disciple to the crucial figure safeguarding the sect's lifeline, Lu Xian uses nothing but a toolbox to repair the path of immortal cultivation beneath everyone's feet.
