According to the Inspection Envoy

Eight years ago, Song Liyin, the minister of Dali Temple, was ordered to investigate the murder of a royal concubine, which led to the idea of ​​rebellion in the small country of Lixiao. In anger, the emperor declared war on the Lixiao Kingdom. In order to avoid a palace coup, Song Liyin petitioned to go to Huyue Province, an undeveloped and stable area in the south, and be reinstated as a local magistrate. On the way to Huyue from the Song family, apart from Song Yusheng, the eldest son of the Song family who was ill, Princess Mingyang and Song Qing, the second child, stayed behind to take care of them. There is also Song Ming, the boss who is still studying in the Hanlin Academy. The rest of the people all died in Jinghu Lake. The way of death was very bizarre. There were no external injuries or signs of struggle. It was as if they all died in an instant. Princess Mingyang, who was far away in the capital, couldn't accept the news when she heard the news, and left with her husband Song Liyin just a few months later. Since then, the three children of the Song family have lost their parents, and these three children have been pitiful. From that day on, their fates were all rewritten.
