Shen Yuan, having uncovered the secret related to strange phenomena on Emperor Xia's body, would certainly have made preemptive arrangements.
Among the many forces at Shen Yuan's disposal, the one that most effectively repressed strangeness was not humanity's fate, but Dizang, the pagoda spirit who had sat in the 18 Levels of Hell suppressing strangeness for tens of thousands of years.
Even those parts of strangeness that had penetrated deep into True Spirits, which even the Six Paths of Reincarnation could not cleanse, could still be suppressed by Dizang in the Endless Hell.
Thus, as soon as the Netherworld dispatched the second batch of supernatural beings to the Imperial Capital, Shen Yuan had secretly used an Imperial Edict from the Fengdu Emperor to have Dizang covertly follow the supernatural beings to take a position in the Imperial Capital.
The seemingly critical Netherworld Commander Leopard Tail was merely a distraction; Dizang was Shen Yuan's true contingency plan.
