Wang Teng, a native of the Taixuan Realm, receives almost nothing from his inheritance except a manual on pig slaughtering called The Way of Health Preservation. What he doesn't know is that his master, Master Zhang, has already chosen him as a vessel for possession. Relying on his self-created cultivation technique, The Art of Pretending to Be an Immortal, Wang Teng turns make-believe into reality. At the Reliance Sect, he rises from an affiliated disciple to become the so-called Half-Mountain King, outsmarting and battling players from another world who bring disasters wherever they go. His senior brothers and sisters are successively dragged into his reckoning, while the sect's peak masters fall one after another in battle. As the Heavenly Dao shatters and two worlds overlap, Wang Teng ultimately uses himself as bait, harnessing the collective faith of all living beings to fight Master Zhang in a final battle. They perish together, and the world resets. Everything returns to Baixi Town, where a young man once praised by his father as having the makings of a Great Emperor pushes open the door, a faint trace of immortality on his face.
