At the Immortal Alliance public trial, Chi Yanfeng removed Huo Zhu's immortal bones in public, and expelled this once-in-a-century genius from his cultivation. Su Zuiyin defended him desperately, but was silenced by the sect. The two fell into the devil's abyss, and Huo Zhu was inhabited by the remnant soul of the ancient demon king, who used the immortal bones to rebuild the devil's path. Thousands of years later, he returned to Central Continent with his army of demons, Ruan Ningshuang, and Gu Wuyan, only to discover that the immortal bones were involved in the secret of reincarnation. Chi Yanfeng had secretly betrayed the sect, and Jiang Buyu handed over evidence of seven crimes in Tianji Tower. When Su Zuiyin used Shen Nong's fragments to help Huo Zhu recover the immortal bones, heaven sent a thunder disaster - it turned out that the demon king and the immortal bones were two sides of the same coin.
