After the ministers invited the fourth prince, Prince Liu Xu, a significant event occurred that evening. His drink was spiked with opium, which led him to meet a stranger woman who stayed with him in the room the whole night. As a result, a child was conceived. After several years, the prince's life remained restless, so he searched for the woman who was with him all night, especially after learning that she carried his child. Will he be able to find his mother and child, or will this be the reason for him to be removed as a prince of the Yuan dynasty?
