Scaring Me
Who said that Xu Rouguang would remain ignorant for days? What was Xiao Yi's use to him right now if the man couldn't serve as his information guy now that he wasn't affiliated to Heaven?
Actually, Xu Rouguang didn't force Xiao Yi, but Xiao Yi was so willing as if his service to Xu Rouguang was as long as the general was alive, not Severed Glacier or any of his reincarnations.
That was why Xu Rouguang was aware that being the Netherworld King was more of being the biggest big-shot in the Abyss. The Netherworld King was the supreme existence in the Abyss that even Heaven had no counterpart for. He was the being that would collect the dead souls that were not allowed to reincarnate, be it gods or any other creatures in existence. His army was only made of gods because they were the most powerful under him.
