A thousand years ago, Xiao Xuan, the ancestor of the Xiao clan, exhausted his bloodline power in an attempt to reach the Dou Di realm. On the verge of death, he entrusted the Xiao clan to the Gu clan. Unexpectedly, a thousand years later, the once-greatest imperial clan had declined into a third-rate family. Its patriarch, Xiao Zhan, was trapped at the Great Dou Master level, unable to advance any further. The Gu clan monopolized the Heavenly Tomb's entry quota, and all the ancestral treasures had been lost. When Xiao Xuan's remnant soul awakens, he angrily questions the Gu clan's conduct and declares, 'If this is how the Gu clan treats us, I'll personally settle the score for the Xiao clan!'
