Gu Chen alone guarded the Imperial Pass for one hundred thousand years, blocking exotic monsters and protecting the Cangmang Realm, only in exchange for his family facing disaster. The Ancient Emperor forcefully seized Gu Qingxue, a genius of the Gu family, while the imperial clans who had once received favors looked on coldly. The Gu family ignited the Realm-Passing Divine Incense, and a wisp of Gu Chen's divine sense descended upon his homeland, abandoning his pass-guarding rewards in exchange for the peak cultivation of the Imperial Realm, returning powerfully to settle accounts with the faith-breaking imperial clans. However, he discovered that becoming an immortal was actually a startling scam: the demon world's army was pressing heavily on the border, and the immortal world secretly plotted to calculate the lower realm. While protecting the Gu family, Gu Chen fought against the demon world and the immortal world, vowing to tear open the truth that was covered up one hundred thousand years ago.
