Unparalleled General

I was reading a novel at night and actually traveled into the world of a novel about a peerless general. He rescued a princess, quelled bandits, followed the emperor's order, trained his troops, and met a woman who was exactly the same as the one he had a crush on in the real world. However, it was a time of war. Iron-blooded men should protect their families and the country. They should not be trapped by the love of their children. Men should fight on the battlefield and pacify the world with a spear! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
