Chen Mo, a graduate student in the history department, woke up and found that he was a poor scholar about to be executed in the late Northern Qi Dynasty. And the general's son Zhao Lie, who stood outside the execution ground and watched coldly, was the butcher who recorded the "Burning Nine Cities" in the history books. In order to survive, Chen Mo used half of the history books to deduce the changes in the troubled times, and formed a strange life-and-death alliance with Zhao Lie. From the beacon fire at Yanmenguan to the Jinling Palace Incident, from the Mobei Business Road to the Jiangnan Water Village, two young people crushed by fate, one burned the old order with a cold-fire strategy, and the other crushed the new conspiracy with the force of a prairie fire. When the real man behind the scenes showed his fangs, Chen Mo realized that what he traveled through was not only history, but also a chess game spanning thousands of years. Gu Huai's hidden trade routes, Su Wan's blood-blade intelligence, Zhou Ning's grain and grass arena, and Li Chong's battle-hardened armor will all become key pieces that rewrite the trajectory of the world.
