The Ancient God of Chaos, Hunluan and the World Eater, An Shizhe asked the Long Clan what they wished for them to lend a hand for. The letter that was passed through them was extremely important to them. This is the first letter that allows them to know that their son had found them. Though as gods they are able to do as they wish, they tried not to do so. After all, they are undergoing some kind of trial in which they need to follow some kind of rules.
It's already worrying that when they are supposed to get their memories sealed in this world, they wake up without a change. Now there is news about the existence of chaos flowers in this world which meant that chaos had already been here even before they arrived. Chaos is an existence that is beyond the world's control. Only Hunluan who was born from it had the capability to control chaos. Even the God of Destruction, well known for his strength, can't say he can fully control such an unpredictable thing.
