After the demise of the Dayin Dynasty, Dayin's land was owned by Jingguo. The concubines of Queen Dayin's harem were also sent to Quecheng, the capital of Jingguo. All his descendants should also be sent, but one of them was missing - Princess Anping, the youngest princess of Dayin.
Yu Wenhao, the young king of Jingguo, launched a secret pursuit throughout the world. However, what he was looking for was not the escaped person, but the mechanical blueprint on her body that opened the Tomb of Heroes of Dayin.
Dayin Tomb of Heroes, the mausoleum where tens of millions of heroic warriors are buried, is rumored to be buried there. Once it is opened, no country in the world would dare to be an enemy of Jingguo.
The newly enthroned emperor of Jingguo invaded Dayin's royal capital, Quedu, in one night, causing the highest rulers of all countries to lose their dignity. But we also had to send many rare local products in order to achieve harmony and friendship.
Since Dayin was destroyed by Jingguo, the drawings of the Tomb of Heroes are naturally in Jingguo.
The new king of Jingguo secretly trained a team of assassins, named Ying Falcon. Members are spread all over the world, engaged in intelligence collection, message transmission, and major assassination missions.
It was precisely with this secret organization that Yu Wenhao was able to confidently raise his troops to Dayin.
Now, Yingying has one more task, which is to secretly track the whereabouts of the blueprints and kill all those who know that the blueprints are not in Jingguo. Only in this way can Jingguo be able to stand above the remaining ten countries in China.
