Demoted Prince: with a Super Exchange System, I Am as Rich as the Country

He traveled through time and became the tenth prince of the Great Zhou Kingdom. His biological mother was falsely accused of rebellion and executed, and he was demoted to a commoner and sent to the border. When he was about to starve to death, Xiao Changfeng awakened the labor contribution exchange system and recruited laborers to work and create contribution points, which could be exchanged for various items in the super mall. Xiao Changfeng relies on braised egg instant noodles and ham sausages to win over refugees to work for him, and gradually develops and grows. He builds an indestructible city in the desolate land of Mobei, builds an invincible army of one million, and points his sword at the Imperial Capital. Everything lost will be taken back!
