In the second year of Xuanhe, Bianjing was whitewashing peace, the Liao Kingdom building was about to collapse, and the Jin people and cavalry were ready to go.
During a winter snow, Cheng Yuan, a spirit from another world, woke up in Tangyin, Xiangzhou, and met Yue Fei, a young man who was still in the countryside.
Faced with the coming humiliation of Jingkang and the destruction of the country, Cheng Yuan knew that only a passion could not shake the centuries-old problem of the Song Dynasty that emphasized culture and suppressed military affairs. He started his career in arithmetic and criminal studies, and stepped into the turbulent Bianjing court step by step.
At a time when party strife was raging and the fate of the country was in turmoil, he used power as a sword and world conditions as a situation to block Yue Fei's secret arrows from the court and reshape the military and fiscal affairs of the Song Dynasty. The two of them worked together, one civilly and one military, to turn the tide in a desperate situation, and finally brought the Song Dynasty back to life and established itself in the world.
