πI recommend the Legend of the Warhawk to you. The protagonist traveled back to the Anti-Japanese War era and became a double identity undercover personnel. He formed the Warhawk Commando Team, fought the puppet army, killed the traitors, and abused the devils. He subverted the overall situation on the battlefield again and again. He was regarded as a strong opponent by Yamamoto Taro, who was known as the Gun God of the devils, and defeated him as a lifetime honor. I hope you like this fairy's recommendation. Muah ~π
