Gongsun Sheng believed that the birthday card was ill-gotten wealth, so he deliberately robbed it. He had long heard the name of Chao Gai, the king of pagodas, so he went to Dongxi Village, Yuncheng County to seek refuge with Chao Gai, hoping to ask Chao Gai to steal the birthday card together.
At that time, Chao Gai had received a message from the red-haired ghost Liu Tang, and met the three Ruan brothers through Zhiduoxing Wu Yong, who were planning to rob Gang at home. After Chao Gai learned about Gongsun Sheng's intention, he invited him into the back hall to meet Wu Yong, Liu Tang and the Ruan family.

He Tao found out about Chao Gai's seven men pretending to be jujube merchants, and arrested Bai Sheng and tortured him to extract a confession. Bai Sheng failed to survive the sentence and was forced to recruit Chao Gai.
He Tao went to Yuncheng County to urge the county government to arrest the seven Chao Gai men. However, Song Jiang, the superintendent of Yuncheng County, reported the news to Chao Gai in advance, and the leaders Zhu Dian and Lei Heng, who were responsible for the arrest, also deliberately indulged themselves. Chao Gai, Wu Yong, Gongsun Sheng, and Liu Tang were able to escape to the home of the Ruan family in Shijie Village.
Although Chao Gai and his four men escaped, a guest in the village was captured by the government, and they gave the general information about Gongsun Sheng and other six people. The governor of Jeju asked Bai Sheng for a confession again, and Bai Sheng had to confess the names of the six Gongsun Shengs and the residences of the three men of the Ruan family.
The governor ordered He Tao to go to Shijie Village to arrest him. In the battle of Shijie Village, Gongsun Sheng used Taoist magic to raise strong winds.
