When a sniper bullet from the 21st century penetrated the bloody dusk on the outskirts of Yangzhou in 1645 - the time travel of modern special forces commander Lin Feng started a battle for the survival of civilization that transcended the times.
Holding a rifle in hand, facing the death order of "leave your hair but not your hair", his initial choice was simple and direct: to fight violence with violence, and to fight blood with blood. But when the old farmer he rescued trembled and took out four bunches of hair from his oilcloth bag, when the one-legged soldier said at the wedding, "My father can raise chickens and ducks now," and when the beloved female medical officer stood in front of the enemy's wounded soldier's bed and asked: "The world you want to build can't tolerate a dying person?" - Lin Feng found that the most difficult thing to defeat was not the Eight Banners cavalry, but the high wall in his heart that "people who are not my race will have different hearts."
