Xie Kong, the most useless head disciple of the Oblique Moon and Three Stars Cave, was left behind on the mountain by his master to guard the gate. Guarding the empty sect, he persuaded batch after batch of immortal-seekers to leave, and also accepted a monkey who knelt at the gate for ten years. Learning on the spot and faking being an immortal to teach his disciple, he turned the monkey into the Great Sage Equal to Heaven. Yet a slip of paper overturned his three thousand years: his master and three thousand fellow disciples had long since died. With hair turning white overnight and breaking through realms to be reborn, he brandished a rusted sword and slaughtered his way up to the Nine Heavens, only to discover that the truth of the massacre was far heavier than he had imagined—his fellow disciples used their lives to build a city wall, keeping the heaven-swallowing darkness outside the gate.
