The two gradually got closer, and Liao Chen struggled between cultivating himself and saving her. The villain Yang Zhongxian sent dead soldiers to investigate but was blocked. The emperor forced the marriage and Lingyin Mountain was sealed. Ling'er put on her wedding dress and left the mountain. She finally realized that protection is more important than self-cultivation. She broke into the main hall during the wedding ceremony and defeated powerful enemies to protect her in front of her.
