Transformed into the evil sword of the villain, I repeatedly jumped on the edge of death every day. If I wasn't held by him, my spiritual power would dissipate and I would turn into scrap metal. But he happened to be a sick beauty who was seriously injured and was being hunted by the righteous! In order to survive, I am a unique weapon that helps him kill enemies during the day, and a power bank that actively throws himself into his arms at night. I thought we were just getting what we needed, but it wasn't until he was willing to make enemies of the world to protect me that I realized that the Bai Yueguang that this Crazy Demon Lord had hidden in his heart for three hundred years was actually me? !
