I recommend the following novels to you. They are all about killing on the battlefield and being iron-blooded: 1. "My Journey Begins in 1641": An engineer from Jinbei Heavy Industries changed the turning point of history at the end of the Ming Dynasty. It was a story of bloody battlefields and brothers who lived and died. 2. "The Broken Spear Under the Horseshoes": The protagonist was a man from the Dark Age. He endured the battlefield and the countryside, immersed in the war under the roar of the hooves. 3. <Battlefield Massacre>: A young man fights in the mercenary world. Blood and fire temper his will. His superb medical skills and powerful skills conquer countless forces. I hope you like my recommendation, Mwah ~😗
