“All right, let’s talk about something else.” Cheng Xin smiled. “You want to know what I’ve been up to? After you left—”
“I know everything. I’ve always been with you.”
Tianming’s tone was steady and calm, but Cheng Xin’s heart quaked. Yes, he had always been with her, observing her life through the sophons. He must have seen how she had become the Swordholder, how she had thrown away that red switch in the last moments of the Deterrence Era, how she had endured in Australia, how she had lost her sight from extreme pain, until, finally, how she had picked up that tiny capsule.… He had gone through all these trials with her. It was easy to imagine that when he had seen her struggle through her hell from several light-years away, he must have suffered even more pain. If she had known earlier that this man who loved her had crossed the light-years to keep watch over her, she would have been comforted. But Cheng Xin had thought Tianming lost forever in the vastness of space, and most of the time, she had never believed that he still existed.
“If I had known…” Cheng Xin muttered, as if to herself.
“You couldn’t have.” Tianming shook his head.
The emotions Cheng Xin had pushed deep down surged again. She forced herself to not cry.
“Then … what about your experience? Can you tell me anything?” Cheng Xin asked. This was a naked attempt at gathering intelligence. But she had to take a step.
“Hmmm, let me think…” Tianming pondered.
The yellow light came up. Tianming hadn’t even said anything. This was a serious warning.
Tianming shook his head resolutely. “I can’t tell you anything. Absolutely nothing.”
Cheng Xin said nothing. She knew that as far as her mission was concerned, she had done all she could. All she could do now was to wait and see what Tianming wanted to do.
“We can’t talk like this,” said Tianming, and sighed. Then, with his eyes, he said more: for your sake.
Yes, it was too dangerous. The yellow light had gone on three times already.
Cheng Xin sighed in her heart. Tianming had given up. Her mission would be unfulfilled. But there was no other choice. She understood.
Once they had set aside the mission, this space that contained them, a few light-years across, became their secret world. Indeed, between the two of them, they needed no language; their eyes were able to say everything they needed. Now that she was no longer so focused on the mission, Cheng Xin could feel even more meaning in Tianming’s gaze. She was brought back to her college days, when Tianming had looked at her often in this way. He had been discreet, but her girlish instincts had felt him. Now, his gaze was infused with his maturity, and the sunlight crossed light-years to submerge her in warmth and happiness.
Cheng Xin wanted this silence to last forever, but Tianming spoke again. “Cheng Xin, do you remember how we used to spend our time when we were little?”
Cheng Xin shook her head. The question was unexpected and incomprehensible. When we were little? But she successfully hid her surprise.
“So many nights, we’d call each other and chat before going to bed. We made up stories and told them to each other. You always made up better stories. How many stories did we tell each other? At least a hundred?”
“Yes, I think so. A lot.” Cheng Xin used to be unable to lie, but she was surprised to find herself performing well.
“Do you remember any of those stories?”
“Not many. I’ve moved far away from childhood.”
“But it’s not so far away from me. During these years, I’ve told those stories—yours and mine—again and again.”
“To yourself?”
“No, not to myself. I came here, and I felt the need to give this world something. But what? After much thinking, I decided that I could bring childhood to this world, and so I told them our stories. The children here love them. I even put out a collection, Fairy Tales from Earth, which was very popular. This book belongs to both of us—I didn’t plagiarize you; all the stories you told me still have your name in the byline. So you’re a famous author here.”
Based on the still very limited knowledge humans had of the Trisolarans, sex among them involved the two partners melding their bodies into one. Thereafter, the combined body would split into three to five new lives. These were their descendants, and the “children” referred to by Tianming. But these individuals inherited part of their parents’ memories, and were relatively mature at birth, which differentiated them from human children. Trisolarans really didn’t have childhood. Both Trisolaran and human scholars believed that this biological difference was one of the root causes of the great differences between their cultures and societies.
Cheng Xin became anxious again. She knew now that Tianming had not given up, and the key moment was here. She had to do something, but she had to be very, very careful. Smiling, she said, “Although we can’t talk about anything else, surely we can talk about those stories. Those belong only to us.”
“The stories I made up or the ones you made up?”
“Tell the ones I made up. Bring me back to my childhood.” Cheng Xin did not hesitate at all. Even she was surprised at how quickly she had caught on to Tianming’s plan.
“All right. Then let’s not talk about anything else. Just the stories. Your stories.” Tianming spread his hands and looked up, clearly addressing those monitoring the conversation. His meaning was clear: You shouldn’t object to this, right? Everything is safe. Then he turned to Cheng Xin. “We have about an hour. Which story? Hmmm … how about ‘The New Royal Painter’?”
And so, Tianming began to tell the story. His voice was deep and soothing, as though he was chanting an ancient song. Cheng Xin tried hard to memorize, but she was gradually absorbed by the story. Much time passed as Tianming spun his fairy tale. He told three stories, all connected to each other: “The New Royal Painter,” “The Glutton’s Sea,” and “Prince Deep Water.” After he finished the last story, the sophon put up a countdown, indicating that they had only one minute left.
The moment of parting was at hand.
Cheng Xin awakened from the dream of the fairy tales. Something struck her heart hard, and it was almost unbearable. She said, “The universe is grand, but life is grander. We’re certain to meet again.” Only when she was done did she realize she had almost repeated Sophon’s farewell.
“Then let’s pick a spot to meet, somewhere other than the Earth, somewhere in the Milky Way.”
“How about at the star you gave me? Our star.” Cheng Xin didn’t even need to think.
“All right. At our star!”
As they gazed at each other across the light-years, the countdown reached zero, and the image disappeared, returning to the snow of white noise. Then the unfolded sophon turned purely reflective again.
The green light went off. Now none of the lights were on. Cheng Xin understood that she was now on the precipice of death. On a ship in the First Trisolaran Fleet several light-years away, the conversation between her and Tianming was being replayed and examined. The red light of death could go on at any moment, and there would be no warning yellow light.
Against the unfolded spherical surface of the sophon, Cheng Xin saw the reflection of her own dinghy and herself. The half of her dinghy facing the sophon was completely transparent, like an intricate locket dangling from a necklace, and she herself was a picture placed in the locket. She was dressed in a snow-white lightweight space suit, and she appeared pure, youthful, beautiful. She was surprised by her own eyes: clear, placid, showing nothing of the surging waves inside her. She felt comforted as she imagined this lovely locket hanging on Tianming’s heart.
After an unknown amount of time had passed, the sophon disappeared. The red light did not come on. The space outside looked the same as before: The blue Earth appeared again in the distance, and behind it the Sun. They were witness to all.
She felt hypergravity again. The dinghy’s thruster was accelerating, and she was going home.
During the few hours of the return voyage, Cheng Xin adjusted the dinghy’s hull so that it was completely solid. She sealed herself in and turned herself into a memorization machine. Again and again, she repeated Tianming’s words and his stories. The acceleration stopped; the dinghy coasted; the thruster turned around; the dinghy decelerated—she didn’t notice any of it. Finally, after a series of tremors, the door opened, and the terminal station port’s light spilled in.
Two of the officials who had accompanied her to the station met her. Their faces were impassive. After a simple greeting, they brought Cheng Xin across the port to a sealed door.
“Dr. Cheng, you need to rest. Don’t dwell on the past. We never held much hope that you’d get anything of use,” the PDC official said. And then he gestured for Cheng Xin to enter the sealed door that had just opened.
Cheng Xin had thought this was the exit to the port, but she found herself in an extremely small room. All the walls were made of some dark metal. After the door closed behind her, she couldn’t even see the seams. This was not a place of rest. It was simply furnished, with a small desk and a chair. On top of the desk was a microphone. Microphones were rarely seen in this age, and only used for high-fidelity recording. The air in the room had an acrid smell, almost sulfuric, and her skin felt itchy—the air was clearly heavy with static electricity.
The room was filled with people: All the members of the special team were here. As soon as the two officials who had received her entered, their expressions changed. They now looked as anxious and concerned as the rest.
“This is a blind zone for the sophons,” someone said to Cheng Xin. Only then did she realize that humans had finally achieved the technology to shield themselves from the ever-present listeners, though it was only possible within extremely confined spaces like this one.
The fleet chief said, “Please recite the entirety of your conversation. Don’t omit any details that you can recall. Every word may be important.”
Then the members of the special team left the room one by one. The last to depart was an engineer who explained to Cheng Xin that the walls of the sophon-free room were all electrified, and she should be careful to not touch them.
Only Cheng Xin was left. She sat down at the desk and began to record everything she could remember. An hour and ten minutes later, she was done. She drank a bit of water and milk, took a brief break, and began to record a second time, then a third. When she was ready to record for the fourth time, she was asked to recount the events backwards, with the latest events first. The fifth recording was done under the guidance of a team of psychologists. They used some drug to keep her in a semi-hypnotized state, and she didn’t even know what she said. Before she knew it, more than six hours had passed.
After she had finished the last recounting, the special team filled the room again. They embraced Cheng Xin and shook her hand. Hot tears flowed, and they told her she had accomplished a heroic deed. But Cheng Xin remained numb, like a memorization machine.
Only when she had returned to the comfortable cabin in the space elevator did the memorization machine in her brain shut off. She became a person again. Extreme exhaustion and waves of emotion overwhelmed her, and as she faced the approaching blue sphere of the Earth, she began to cry. Only one voice echoed in her mind:
Our star. Our star …
* * *
At that moment, on the surface more than thirty thousand kilometers below, Sophon’s house went up in flames. The robot that had been Sophon’s avatar was burnt up as well. Before this, she had proclaimed to the world that all the sophons in the Solar System would be withdrawn.
People only half-believed Sophon. It was likely that only the robot was gone, but a few sophons remained on the Earth and in the Solar System. But it was also possible that she was telling the truth. Sophons were precious resources. What remained of Trisolaran civilization was in a fleet of spaceships, and they wouldn’t be able to construct any new sophons for a long, long time. Besides, keeping watch over the Solar System and the Earth no longer had much meaning. If the fleet entered a blind region for the sophons, they might lose the sophons in the Solar System forever.
If the last situation occurred, then the Trisolarans and humanity would lose all contact, and once again become cosmic strangers. A three-century-long history of warfare and resentment would turn into so much ephemera in the universe. Even if they were to meet again because of fate—as Sophon had predicted—it would be in the distant future. But neither world knew if they had a future.
Broadcast Era, Year 7
Yun Tianming’s Fairy Tales
The first meeting of the Intelligence Decipherment Committee (IDC) was also conducted in a sophon-free room. Although most people now favored the view that the sophons were gone, and the Solar System and the Earth were now “clean,” they still took this precaution. Their main concern was that if the sophons were still present, they might endanger Yun Tianming.
The conversation between Tianming and Cheng Xin was publicized, but the real intelligence given by Tianming, the content of the three fairy tales, was kept in absolute secrecy. For a transparent, modern society, keeping such important information secret was a difficult task for both the UN and Fleet International. But the nations of the world soon reached consensus on this point: If the fairy tales were revealed, the world would be swept up by the enthusiasm of trying to decipher them, thereby exposing Tianming. The safety of Tianming wasn’t just important for him individually, he, to date, the only person embedded in an alien society. His position was irreplaceable for humanity’s future survival.
The secret decipherment of Tianming’s message was another sign of the UN’s authority and operational capabilities; it was another step on the way to a world government.
This sophon-free room was larger than the one Cheng Xin had used on the terminal station, though it wasn’t by any means spacious for a conference room. The force field necessary to keep sophons out could enclose only a limited volume.
About thirty people were in attendance. Other than Cheng Xin, two other Common Era individuals were also present: the particle-accelerator engineer Bi Yunfeng and the physicist Cao Bin—both former candidates for the Swordholder position.
Everyone wore high-voltage protective suits because the metallic walls of the sophon-free room were electrified. In particular, everyone was required to wear protective gloves, lest someone tap a wall out of habit, in an attempt to summon an information window. No electronics could function within the force field, thus the room had no information windows at all. To help the force field stay evenly distributed, equipment within the room was reduced to a minimum. Only chairs were provided, and there was no table. Since the protective suits were requisitioned from electrical engineers, the meeting within the metallic room resembled an ancient pre-shift gathering on a factory floor.
No one complained about the crowded, rough conditions, or the acrid smell in the air and the tingling on the skin brought about by the electrified air. After living for nearly three centuries under the constant surveillance of the sophons, being free of the alien voyeurs brought a sudden, fresh sense of relief. The ability to shield space from sophons had been developed soon after the Great Resettlement. It was rumored that those who had entered the very first sophon-free room came down with something called “screen syndrome”: They talked incessantly as if they were drunk, and bared all their secrets to their companions. A reporter described the condition this way: “In this narrow slice of heaven, the people opened their hearts. Our gazes were no longer veiled.”
The IDC was a combined effort by Fleet International and the UN PDC to decipher Yun Tianming’s message. It oversaw the work of twenty-five working groups focusing on different subjects and areas of expertise. The attendees at this meeting were not experts or scientists, but the IDC committee members, who were also the leaders of the working groups.
The IDC chair first thanked Yun Tianming and Cheng Xin on behalf of Fleet International and the UN. He c
alled Tianming the bravest warrior in the history of the human race. He was the first human to successfully survive in an alien world. Alone, deep in the heart of the enemy, situated in an unimaginable environment, he fought on and brought hope to an Earth in crisis. Cheng Xin, on the other hand, had successfully retrieved the intelligence from Tianming through a combination of wits and guts.
In a soft voice, Cheng Xin requested a chance to speak. She stood up and surveyed all those present. “All this is the result of the Staircase Project. This endeavor cannot be separated from a particular man. Three centuries ago, his steadfastness, decisive leadership, and peerless creativity allowed the Staircase Project to overcome multiple difficulties and become reality. The man I’m talking about is Thomas Wade, chief of the PDC Strategic Intelligence Agency. I think we should thank him as well.”
The conference room sank into silence. No one seconded Cheng Xin’s suggestion. For most people, Wade was the very symbol of the darkness in Common Era human nature, the very antithesis of the lovely woman—who had almost been killed by Wade—standing in front of them. They shivered just thinking about him.
The chair—he happened to also be the PIA’s current chief, a successor to Wade’s position, though they were divided by three centuries—said nothing in response to Cheng Xin’s proposal. He simply continued down the agenda for the meeting. “The committee has established a basic principle and hope for the decipherment process. We believe the message is unlikely to contain any concrete technical information, but will more likely point out the correct direction for research. It may contain the guide to the correct theoretical framework for unknown technologies such as lightspeed spaceflight or the cosmic safety notice. If we can get that far, it will bring tremendous hope to humanity.
“In total, we gathered two pieces of intelligence: the conversation between Dr. Cheng and Yun Tianming, and the three stories he told. Preliminary analysis points to the important information being hidden entirely within the three stories. We won’t be paying much attention to the conversation in the future, but I will summarize what we’ve gleaned from it here.
