In the first year of Jingkang's reign, the Jin Army's armor-piercing crossbow penetrated the female wall of Kaifeng. Chen Xiaoman, a soldier guarding the city, pretended to be dead while holding a broken gun, but was dragged into the line of fire by a captain. Behind him are the crying people, and in front of him are Tiefutu and Guaizima. He has no destiny or magical power, only one military rule: those who dare to fight will live, and those who retreat will die. From auxiliary soldier to regular soldier, from flag leader to team general, he survived by repairing armor, knowing formations, and memorizing battle routines, and he also survived and climbed up by wearing robes. It wasn't until he met the Yue family army who froze to death without demolishing their houses and starved to death without looting that he realized that in troubled times there was a flag worth following. But the most difficult thing was not the bloody battle in Yancheng, nor the torrent of iron armor in front of Zhuxian Town, but when the twelve gold medals fell, he knew that returning to the army would be an unjust imprisonment, but he still had to follow Yue Fei to death. This is a cold weapon epic without fantasy or time travel, about a group of small people carrying mountains and rivers with their flesh and blood.
