The spiritual energy is revived and the ancient martial arts is reborn. I was once the most ferocious "human weapon" in the underground world, and there were only dead souls under the Baji Fist. Until I lost my sight and was abandoned by the organization, I hid in the market and rotted in the eternal darkness. The blind girl playing the guqin next door said to me: "Your fist hurts, but it is very righteous." She can "see" the world with the sound of the piano, and she stubbornly believes that Wu is the guardian of students. When the killings of the past were like a shadow, I clenched my fist again to protect her three feet of peace. This time, the fierce and violent Baji Quan method gave birth to the gentleness of protection. From the killing tool to the guardian blade, my martial arts was reborn in the darkness because of her.
