According to a legend, there is a secret treasure "Dong Tian Yi" in Tang Sect. It can predict a list of wicked people in advance and punish them before they do evil. However, Tang Wuyan’s name, Tang Wuyan’s new head, also appeared on Dong Tian Yi, and was forced to flee. Tang Wuyan met the kind-hearted thief Chu Chen. With him, she decided to return to Tang Sect and destroy him. The culprit, the armillary sphere, regains control of their own destiny.
