The original owner was ostracized by his brothers and sisters in the sect for a long time because of his inferior spiritual roots. He also repeatedly took the blame for the heroine Ye Zhenzhen, and ultimately could not escape the tragic fate of his death.

After seeing through Ye Zhenzhen's frame-up plot, she decisively refused to take the blame, took the opportunity to get the jade medal that terminated the relationship between master and apprentice, and successfully left the Wuji Sect.
