In fact, from the moment Jiang Lu tried to see if he could take advantage of Emperor Yin's descent into madness to kill him, Emperor Yin had already sensed his malicious intent.
But at that time, all his energy was consumed in the struggle against Nyarlathotep, leaving him no spare energy to deal with Jiang Lu.
However, he didn't even need to deal with him specifically, because even though Jiang Lu had borrowed An Dan's body and could wield the most powerful divine force beneath the Chief God, he still couldn't break through Emperor Yin's defenses.
The resistance that bogged him down like a swamp was, in fact, the passive protective aura of An Dan.
That thing alone was enough to block all the invincible powers of An Dan's Kingdom of Corpses in the palm of his hand.
Although his main attention was on Nyarlathotep, he did allocate a part of his attention to Jiang Lu, wanting to see what he was planning.
