Ye Xiaotian, a prison guard of the Ministry of Criminal Affairs of the Ming Dynasty, accepted a commission to send a suicide note back to his hometown. He was chased by the family of the man who did not want to divide the family property and fled to Qiandong. Ai Feng, an important official of the Ministry of War, went to Qiandong as the new Dianshi of Hu County to investigate the illegal plot of Yang Yinglong, a powerful person, and was killed by Yang Yinglong. In order to escape the responsibility for the poor public security, Hua Qingfeng, the county magistrate of Hu County, arranged for Ye Xiaotian to impersonate Ai Dianshi. Although Ye Xiaotian was born as a prison guard and had a rough and unruly spirit, he was not willing to be a puppet. During his tenure as Dianshi, he cracked down on the tyrants and bullies, turned Hu County upside down, and by chance, became the real Dianshi of Hu County, thus starting his official career. After being promoted to the position of Tongren Prefecture Procurator, Ye Xiaotian still kept himself aloof and refused to associate with the idle officials who were in office but did nothing. For the sake of a wrongly killed woman, he angrily killed a dandy villain, which put him in a desperate situation. However, he was also loved by the local people and appreciated by the patriotic chieftain of Guizhou, and eventually became a chieftain. Ye Xiaotian, who always believed that the world was bright and that the land under the chieftain's rule was also the king's, joined forces with the patriotic chieftain of Guizhou to curb the expansion of the ambitious Yang Yinglong and became a solid barrier for the court.
