Ye Ziyi was apart of Sun Moon Divine Hall, and was one of the two Mid-tier Overlords sent to Frozen Cloud Asgard by Ye Xinghan to acquire Xia Qingyue.

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 months, which gave Yun Che time to get there and save Frozen Cloud Asgard.[1]

After Yun Che arrived to Frozen Cloud Asgard and the rest of the Nine Thrones he first attacked Ye Ziyi grabbing him by the throat; completely suppressing him to where he couldn't even lift his hands. Yun Che then burnt him to ashed with the Golden Crow Flames.[2]
