简介：A sharp pain suddenly hit me. It was different from the soreness and itching of the flesh. It was a kind of pain, an indescribable pain. The usual pain that penetrated the bone marrow was just a metaphor, but at this moment, it was real and in the bone refining realm. From the outside to the inside, from the skeleton to the bone marrow, everything is changing. Impurities are being removed bit by bit, but the whole process is so painful that his face is distorted.
