Warring States Reformists. I recommend this novel. The protagonist traveled through history and became a historical revolutionary. He beat up his political enemies, chased after his enemies, pushed forward the process of history, opened up wasteland, and farmed. He earned a little money and became a world's debt-holder. He had friends on his left and right, listened to songs and dances, and watched history in his free time. I hope you like this fairy's recommendation. Muah ~😗
