"I am the author of this interstellar sadomasochism. I hold a quantum physics textbook in my left hand and a bloody scalpel in my right hand. From the first encounter in the emergency room to the final trial of the Betelgeuse black hole, I am grazing words in this sea of real and virtual stars - if you hear the resonance of the mechanical prosthetic limbs and the fetal heartbeat, it is the cry for help of Gu Chengze and Lin Xia in the parallel universe."
