Pei Jiuli, the gatekeeper of Jiuli Pass, was accidentally leaked due to the "remnants of the ancient gods" that his family had suppressed for generations. When he was eroded by the treacherous energy and was on the verge of death, he awakened the "cunning pattern fusion" golden finger in the ancestral black armor - which can absorb the treacherous energy to strengthen himself, and integrates warrior combat skills and weird characteristics to form a unique "cunning martial arts" system. From suppressing the treacherous tide on the border to going deep into the ruins of the ancient gods, while fighting against the gradually resurgent forces of the Cthulhu-style evil god, he uncovered the millennium secret of his family's gatekeeping: the so-called "gatekeeper" was actually the "blood sacrifice key" deliberately left behind by the ancient gods... The cool points focus on the fusion of crafty and martial arts. The real-time feedback (such as the instant mastery of the "Spider Web Lock" combat skill after integrating the "Thousand-Armed Giant Spider"), the high-tension battle with Cthulhu's monsters (the "Blood Moon Knife" was cut out from the tentacle group), and the subversive truth of identity reversal (from gatekeeper to game-breaker).
