The process of selecting a subject for the Staircase Program was fully underway, but the effort imposed little direct pressure on Cheng Xin. She was asked to perform some basic tasks such as examining candidates’ knowledge of spaceflight, a primary requirement. Since the pool of candidates was limited to terminally ill patients, it was almost impossible to find someone with the requisite expertise. The PIA intensified efforts to identify more candidates through every available channel.
One of Cheng Xin’s college classmates came to New York to visit her. The talk turned to what had happened to others in their class, and her friend mentioned Yun Tianming. She had heard from Hu Wen that Tianming was in the late stages of lung cancer and didn’t have much time left. Right away, Cheng Xin went to Assistant Chief Yu to suggest Tianming as a candidate.
For the rest of her life, Cheng Xin would remember that moment. Every time, she had to admit to herself that she just didn’t think much about Tianming as a person.
Cheng Xin needed to return to China for business. Since she was Tianming’s classmate, Assistant Chief Yu asked her to represent the PIA and discuss the matter with Tianming. She agreed, still not thinking much of it.
After hearing Cheng Xin’s story, Tianming slowly sat up on the bed. Cheng Xin asked him to lie down, but he said he wanted to be by himself for a while.
Cheng Xin closed the door lightly behind her. Tianming began to laugh hysterically.
No, Cheng Xin had come to ask him to die.
He made another logical deduction that made him laugh even harder, until it was hard to breathe. Based on Cheng Xin’s timing, she could not know that he had already chosen euthanasia. In other words, if Tianming hadn’t already chosen this path, she would try to convince him to take it. Maybe she would even entice him, or pressure him, until he agreed.
His sister had wanted him to die because she thought money was being wasted. He could understand that—and he believed that she genuinely wanted him to die in peace. Cheng Xin, on the other hand, wanted him to suffer in eternity. Tianming was terrified of space. Like everyone who studied spaceflight for a living, he understood space’s sinister nature better than the general public. Hell was not on Earth, but in heaven.
Cheng Xin wanted a part of him, the part that carried his soul, to wander forever in that frigid, endless, lightless abyss.
Actually, that would be the best outcome.
If the Trisolarans were to really capture his brain as Cheng Xin wished, then his true nightmare would begin. Aliens who shared nothing with humanity would attach sensors to his brain and begin tests involving the senses. They would be most interested in the sensation of pain, of course, and so, by turn, he would experience hunger, thirst, whipping, burning, suffocation, electric shocks, medieval torture techniques, death by a thousand cuts….
Then they would search his memory to identify what forms of suffering he feared the most. They would discover a torture technique he had once read in a history book—first, the victim was whipped until not an inch of his skin remained intact; then the victim’s body was tightly wrapped in bandages; and after the victim had stopped bleeding, the bandages would be torn off, ripping open all the wounds at once—then send signals replicating such torture into his brain. The victim in his history book couldn’t live for long in those conditions, but Tianming’s brain would not be able to die. The most that could happen was that his brain could shut down from shock. In the eyes of Trisolarans, it would resemble a computer locking up. They’d just restart his brain and run another experiment, driven by curiosity, or merely the desire for entertainment….
He would have no escape. Without hands or body, he would have no way to commit suicide. His brain would resemble a battery, recharged again and again with pain.
There would be no end.
He howled with laughter.
Cheng Xin opened the door. “Tianming, what’s wrong?”
He choked off his laugh and turned still as a corpse.
“Tianming, on behalf of the UN-PDC Strategic Intelligence Agency, I ask you whether you’re willing to shoulder your responsibility as a member of the human race and accept this mission. This is entirely voluntary. You are free to say no.”
