In his previous life, Yun Qingxu used his own life to save the regent Xuan Yi who was drugged by the Queen Mother, but was regarded as a spy sent by the Queen Mother and neglected in the backyard for ten years. Ten years later, on the night when the regent married the princess, Yun Qingxu burned himself in grief because of the death of his son Yuan'er. Only then did Xuan Yi realize that Yun Qingxu was the savior he was looking for. Yun Qingxu was unexpectedly reborn the day before entering the Regent's Palace. Yun Qingxu made up his mind not to enter the Regent's Palace, but Xuanyi drank him the soup when he stopped the sedan chair. Xuanyi always regarded Yun Qingxu as a spy of the Queen Mother and wanted to shoot her, but at the moment the arrow was shot, he regained the memory of his previous life.
