When the sea is flowing, heroes will show their true colors. At the end of the Five Dynasties and Ten Kingdoms period, society was in turmoil. After Chai Shizong's death, Zhao Kuangyin took advantage of the young emperor of the Later Zhou Dynasty to launch the Chenqiao Mutiny and establish the Song Dynasty. Chai Rong's only daughter, Chai Yan, came to the Wuyi Mountains under the protection of Zhou Zhongchen Lu Qitong and found Cao Chuanfeng, the Minister of Rites during the reign of King Sejong. As a successor of Confucianism, Cao Chuanfeng has always taken it as his mission to help the world. After some calculations, he decided to divide his troops into two groups and let his only disciple Wen Xin escort Chai Yan to Kaifeng. He and Lu Qitong secretly contacted the old ministers of the Later Zhou Dynasty in an attempt to expose Zhao Kuangyin and restore the Later Zhou Dynasty to repay Shizong for his kindness.
At the same time, after consideration, Zhao Kuangyin also sent Zhao Pu to the south to handle Chai Yan's affairs with full authority. In order to avoid incurring condemnation from the world, Zhao Pu did not use the power of Song Dynasty, but lobbied Shisanwu near Panyang Lake to stop Chai Yan. In the Liao Dynasty, General Yelu Chucai decided to secretly help Chai Yan reach Kaifeng in order to deal with Zhao Kuangyin so that Zhao Kuangyin would be exposed to internal and external troubles. In view of Zhao Kuangyin's advantage in time and place, Yelu Chu deliberately spread the treasure map that Chai Yan had the huge wealth of the Zhou Dynasty, thus attracting forces such as Tubo and the Southern Tang Dynasty to come to snatch it, thus fishing in troubled waters.
