(Historical fictional story) In 942 AD, Shi Jingtang, the founder of the Later Jin Dynasty, died and his nephew Shi Chonggui succeeded to the throne. This was the darkest era when rituals collapsed and people's lives were like grass. Shi Chonggui refused to surrender to the Khitan, which opened the door to the Central Plains. Yelu Deguang's 100,000 cavalry were watching with eager eyes. There were only the last four years left before the Battle of Zhongdu Bridge, which led to the fall of Bianliang and the robbery of the Han people.
You Zhaolin, a modern veteran and gold medal salesman, accidentally traveled into the history books because of a mysterious gold-patterned bookmark and possessed the body of a low-level commander of the Forbidden Army. Faced with the inevitable fate of the country, he used tactical skills that transcended his times. With negotiation skills that have an insight into human nature, You Zhaolin is good at dancing in troubled times. From violent games on the streets of Bianliang to the chaos in the court, You Zhaolin used his sales thinking and integrated resources to forge a group of ragtag people into an iron-blooded army.
