Ye Qingsheng was a part of Sun Moon Divine Hall, and was one of the two people sent to Frozen Cloud Asgard to acquire Xia Qingyue by Ye Xinghan.

When he got there he was obstructed by their Snow Goddess’ Veil for seven days and when he finally got through he was obstructed again by Heavenly Firm Jade for six months, which gave Yun Che time to get there and save Frozen Cloud Asgard.[1]

After Yun Che arrived to Frozen Cloud Asgard he destroyed the Nine people with the cultivation of Emperor Profound Realm that were sent along with him and burnt Ye Ziyi, the other Overlord that was with him into ashes,[2] and after seeing that scene, it caused him to be scared out of his mind and immediately escape only to have Yun Che use his Ice Profound Energy to seal him in ice, and cripple him.[3]

Yun Che then went on to use a Profound Handle Soul Search to ask him why and who asked them to attack Frozen Cloud Asgard, which led Yun Che to finally lose his patience and use his Profound Handle to retrieve all of his memories.[4]
