In the Dayin Dynasty, the way of heaven declined, demons appeared frequently, and prophecies stated that a savior would appear. Nangong Xiao Zhaoren pretends to be crazy and stupid, but in fact he has the heart of the ancient sword, but he doesn't want to be the savior. He accidentally got a system that can redeem items. The higher the acting value, the more powerful the items that can be redeemed. With the help of the system, he can exchange skills and experience cards to revive the ancient sword heart. In the eyes of others, he is a "weak chicken", but he secretly saves people and kills monsters. After that, he will definitely use the system to change his destiny and save the world.
