A dragon was suppressed under my grandfather's Yin and Yang pawn shop, but I accidentally released it. As a result, I contracted an evil disease and almost lost my life to the dragon.
In order to save me, my grandfather had to take me into the industry. After that, I also suffered from the curse of my family for generations.
The evil dragon is inhabiting my body and wants to take over my body at all times. In order to survive, I can only embark on the yin and yang trade and make a living by selling yin. I suppress the evil dragon while looking for a way to lift the family curse...
