According to legend, in order to expand the territory, the emperor sent troops to conquer the country. In order to obtain more land, the emperor did not hesitate to send out famous generals. Chu Heling, the daughter of the general Chu Menglong, led an elite army. Under the emperor's order, he took over a large area of land in the north within three years and secretly searched for the ancient land of Huaijiang Mountain. On a seabed in the north where the Iron Cavalry has not yet set foot, there lives a group of sharks who have lived in this inland sea for generations. One is a selfless general, and the other is a mermaid with a cold face and a warm heart. They have known each other all the way.
