If the person before them was indeed the rumored Ye Chen, then everything that seemed illogical now made perfect sense.
Ye Chen could kill a half-step quasi-Immortal Emperor, so it was only natural for him to sweep through the dark creatures in the land of darkness.
The gap between a quasi-Immortal Emperor and an Immortal King was unimaginable. Even a half-step quasi-Immortal Emperor could easily annihilate countless Immortal Kings, just like He Wushuang from Another Domain. After breaking through to a half-step quasi-Immortal Emperor, no matter what methods the Immortal Kings used, they couldn't harm him. Even if there were three thousand or five thousand, it was only a matter of time before He Wushuang slaughtered them all.
Ye Chen could kill He Wushuang, so it was perfectly reasonable for him to swiftly annihilate the Imperial Light-level dark Immortal Kings in the land of darkness.
