Ming Ge Xing Jun did tell Qingqing a way to remove traces, that is, to remove the strings on the floating pipa, but Ming Ge Xing Jun did not tell Qingqing that the strings on the floating pipa were made of ribs found in the snow. In fact, Ming Ge Xing Jun knew everything for a long time, and he kept it a secret to protect his own interests.
All the causes and effects are under the control of Ming Ge Xing Jun. Only when Qingqing meets Xue Qian can he win the Nuwa Stone and the supreme God of Yuan Yin. Xing Jun Ming Ge has always been unwilling to be an unknown little fairy. What he wants to do more is a new face that can control the demons in heaven. If he wants to fulfill this wish, he will get the powerful Nuwa stone and the supreme Yin God.
Although Ming Ge Xing Jun arranged for Qingqing to meet Xue Qian, the purpose was to let them cross the border and give him a chance to steal cultural relics, but he didn't want them to really be together, and he was afraid that their strength would prevent his plan from being implemented. So, he arranged a sadistic relationship between them. Although they met, they both ended in love and were not allowed. In the end, Xing Jun didn't realize his wish, but died at the hands of the Dragon King.
