Military mechanic Han Han accidentally traveled back to the Shaoxi period of the Southern Song Dynasty and became a poor boy who was abandoned by his family. When the nomadic iron cavalry was about to break through the prosperity of Jiangnan, and when the court was still arguing about "war and peace," Han Han discovered that the smart chip he carried with him had actually merged with some mysterious power of this era. He picked up abandoned bronze gears from the ruins, used modern mathematics to recalculate the trajectory of the trebuchet, and turned the few words in "Mengxi Bi Tan" into a real war machine.
However, in these troubled times, what is more dangerous than the golden soldiers is the human heart. Su Wanrou, the daughter of the Minister of Household Affairs, is a gentle and understanding flower in front of others, but behind the scenes, she is trying to keep Han Han's amazing talent firmly in the palm of her hand. When the smoke is everywhere and when loyalists are wronged, Han Han and his wolf team vow to use steel and flames to fight a bloody journey belonging to the poor family in this cold era. He wants the world to understand that knowledge is the most terrifying weapon of this era.
