She is Chu Yunping, the youngest master of the Taiyi Sect. She has only been around for sixteen years, but she is bound to the altar by the sect's rules and the seal of heaven. He is Xie Zhuying, the orphan boy she brought back, from ignorance to attachment to deep-rooted love.
"Master, my disciples will always respect you and protect you."
A child's words eventually become a prophecy.
When ambiguity is exposed, rules turn into sharp edges. He became a demon for her, but she was tortured to protect him, and her love was taken away by the law of heaven. When they met again and faced off in front of the battle, her eyes were as indifferent as frost: "The devil must be punished."
It wasn't until she sacrificed her body and stained the seal with her blood that he realized that in this game of chess, the way of heaven was based on the common people and their sincerity. In the next thousand years, the Demon Lord went crazy and the way of heaven existed alone. In this world - there was no longer her, nor was there the young man who stretched out his trembling hand to her under the lamp.
