At the end of the Qing Dynasty and the beginning of the Republic of China, Zheng Ze, a young man from Hejian Prefecture in Zhili, encountered great changes in his family. He had no choice but to come to Tianjin to work and pay off his debts. However, he never thought that he would be involved in a dark web of overt and covert interests. They formed life-and-death friendships in the Nine-Nation Concession, but they also lost several years of youth in the ride, their budding love was also strangled, and they became the scapegoat for brotherly strife.
Years later, Zheng Ze had nowhere to go and once again returned to his disciple's home in Hejian. He digested the cruel truth of betrayal and finally realized that only by leaving home to find his missing mother could he have a real home. On the way to Hetao to find his mother, Zheng Ze saved a Shanxi tycoon out of his wits and was rewarded for it. After the tycoon passed away, he fulfilled his promise to the tycoon and helped his daughter consolidate his power. However, he was slandered and plotted several times by his enemies. He was later rescued by Mongolian doctors in the Wula Mountains. The kind and tolerant Mongolian Eji used his gentle hand to resolve the raging hatred in Zheng Ze's heart.
Zheng Ze, who returned from his injury, left Shanxi and returned to Hetao in love, where he got married and started a business, becoming the embodiment of justice and the uncrowned king of the Hetao area.
