The City of Sunken Dragon

In the seventeenth year of Jianheng's reign, Emperor Yongxi Xiao Jin planned a shocking chess game in order to completely regain imperial power. He allowed the five major families to segregate themselves hereditarily and fight against each other. He regarded the world as a chessboard and the people as pawns, intending to firmly hold all power in his hands after all forces were defeated. Zhennan Marquis Zhao Jingyuan guarded the southwest border, which was the biggest worry for Emperor Yongxi. Emperor Yongxi secretly allowed Pingjiang Bo Chen to deduct the quota of Shen Longgu from the border army, and colluded with the barbarians to assassinate Zhao Jingyuan, claiming that he was seriously injured and unconscious, and his life or death was uncertain. Hundreds of thousands of barbarians are pressing down on the southwest border. Tens of thousands of soldiers have no armor to wear or weapons to carry, and the people are displaced.
