In the "Yong Dynasty", there are constant natural and man-made disasters. The heroine is an orphan girl who was hit by floods. She fled to the capital with her young brother. She accidentally found the "Jade Seal of the Kingdom" left by the late emperor (actually a token that can transfer the secret silver of the treasury). The prince who visited privately in disguise mistakenly thought that she was the "man of destiny". The heroine uses mithril to provide disaster relief, and gradually grows from a peasant girl to a "adopted daughter" who can influence the court situation, but she is involved in the struggle between the prince and the kings.
