Crown Prince Xiao Dingquan is not favored by his father. After experiencing a series of events such as the Guanli case, the Chunwei leaked questions case, the military horse case, and the nursery rhyme case, Xiao Dingquan gradually matured and grew up, and became more determined to value Taoism over technique. After the King of Qi was demoted and left Beijing, Xiao Dingquan wanted to live a peaceful life with Lu Wenxi, but found that Lu Wenxi was threatened by an unknown force. Xiao Dingquan did not want to see any more fights and wanted to use the marriage of the King of Zhao to resolve the dispute. Xu Changping and Lu Wenxi helped Xiao Dingquan reverse the situation at a critical moment. The three of them joined forces and finally exposed the person behind the scenes. When the news of Gu Silin's death suddenly came, Xiao Dingquan went to Changzhou in person to calm the situation. The emperor finally regretted it and apologized to Xiao Dingquan.
