The Murong clan, who turned as Han Seal, shouldered the mission of killing the Evil Nest for a scam of becoming immortals. As Murong's last exorcist, Ye Zi became the abandoned son to seal the Evil Nest again for the selfish interests of the royal family and the Immortal Mountain. The tortured Ye Zi eventually degenerated into a demon and started a centuries-old battle with Zhang Wu, who had escaped from the control of the evil nest with the help of Leah.
