The moment chaos energy was mentioned, Archangel Jophiel (Hei'An), who seemed to be so confident before looked churned off. Satan looked extremely interested instead, as Chaos energy was one of the purest existence that can make him stronger. Archangel Michael was observing the reaction of the two intruders of his world.
The one whose soul was similar to his obviously backed off after hearing about chaos energy. On the other hand, the flirty bastard beside him looked like he wanted to devour him instead.
Chaos energy was a wild natural power that only the Ancient God Hunluan can control without getting mad. Likewise, even though it is a power that he can wield, controlling it completely was beyond that. As he was only an incarnation and not the Ancient God of Chaos's reincarnation.
