There Are Two Gods Living in My Body, One Thought Can Kill All Gods

I have a brother. Those with Dragon King bloodline would not live past forty. He told me that he would accompany him to Beiling Pass in two years. He was going to an altar to save his life. I didn't promise him. I just stood on the school field with him every day and practiced sparring, from hitting once and taking three breaths to hitting six times in a row without stopping. I punched him, and he blocked it. None of us mentioned the altar again. There is another person. Ning Wan. She is a gray bird, her whole body looks like she was fished out from a pile of coal, with gray veins running down half of her arms. When I injected the serum into her, she asked me, "What are you trying to do?" I told you that no one of you should die on the way. No one in the North will live long. But I want to give it a try - wake up both gods and see if I can give one a few more years of breathing.
