  After passing through the first ring, the weight increased further, and free-falling was no longer safe. Escalators appeared on the wall of the “well,” one going up and one going down. Cheng Xin observed the passengers riding up and saw that they were dressed casually, indistinguishable from Earth dwellers. The wall of the well had many information windows of different sizes, and more than a few of them were broadcasting the image of Cheng Xin stepping onto the space elevator more than twenty hours ago. But at the moment, Cheng Xin’s four escorts surrounded her, and she was also wearing her wide-framed sunglasses. No one recognized her.

  As they descended, they passed through seven more concentric rings. As the diameter of each successive ring grew, the curvature of the corridors to the sides became less noticeable. Cheng Xin felt as though she was passing through strata of history. Each ring used different construction material from the rings before it, and looked newer. Each ring’s method of construction and decorative style formed a time capsule of an age: the repressive militaristic uniformity of the Great Ravine; the optimism and romanticism of the latter half of the Crisis Era; the hedonistic freedom and indolence of the Deterrence Era. Before the fourth ring, the cabins in the rings were integrated into the structure of the rings, but starting with the fifth ring, the rings only provided construction spaces, and the buildings in the rings were planned and constructed later as additional fixtures, showing a rich variety of styles. As Cheng Xin descended through the rings, signs of this being a space station gradually faded, and the environment resembled daily life on the surface more. By the time they reached the eighth ring, the outermost ring of the station, the construction style and scenery were indistinguishable from a small city on the surface. The corridor looked like a bustling pedestrian promenade. Add to that the standard gravity of 1G, and Cheng Xin could almost forget that she was in space, thirty-four thousand kilometers above the Earth.

  But the city scene soon disappeared, as a small motor vehicle brought them to a place where they could see space again. The entrance to the flat hall was marked with “Port A225,” and a few dozen small spacecraft of various designs parked on the smooth, plazalike floor. One side of the hall was completely open to space and the stars spinning around the station. Not too far away from them, a bright light started to glow, illuminating the whole port. Gradually, the light turned from orange to pure blue, and the spaceship that had turned on its engines lifted off the floor, accelerated, and shot into space from the open side of the port. Cheng Xin was witnessing a technological miracle that had become commonplace for others, but she couldn’t figure out how it was possible to maintain atmosphere and pressure in space without the area being completely enclosed.

  They passed by the rows of spacecraft until they arrived at a small open space at the end of the port. There, a small spaceship—a dinghy, really—sat by itself. Next to it stood a group of people who had apparently been waiting for her. The Milky Way slowly swept by the open side of the port, and its light cast long shadows from the dinghy and those standing next to it, turning the open space into a giant clock, over which the roving shadows acted as hands.

  The group next to the dinghy consisted of the special team convened by the PDC and the fleet for this encounter. Cheng Xin knew most of the members—they had attended the Swordholder handover ceremony seven years ago. The two team heads were the rotating chair of the PDC and the chief of staff for the fleet. The rotating chair was new, but the fleet chief was the same person as before. These seven years, the longest in the history of the human race had left indelible marks on their faces. No one said anything as they silently shook hands and silently remembered.

  Cheng Xin examined the dinghy before her. Short-range spacecraft now came in a variety of shapes, but the streamlined profile popular in the imagination of past generations was absent. This dinghy had the most common shape: a sphere. It was so regular that Cheng Xin couldn’t even tell where the thruster was. The dinghy was about the size of an old medium-sized bus. It had only a serial number and no name. This common vehicle was going to carry her to the meeting with Yun Tianming.

  The meeting was to take place at the point where the Earth’s and the Sun’s gravities balanced each other: a Lagrangian point about 1.5 million kilometers away. The sophons would facilitate the meeting with their real-time link with the First Trisolaran Fleet. There would be both voice and video.

  Why conduct the meeting in space? In an age where neutrino communication was possible, being in space wasn’t much more isolated than being on the surface of the Earth. Sophon had explained the request as symbolic: The meeting should occur in an isolated environment to show that it was independent of both worlds. The Lagrangian point was chosen to allow Cheng Xin’s position to be relatively stable. Also, it was the long-held custom among Trisolarans to conduct meetings at points of balance between celestial bodies.

  That much Cheng Xin already knew, but now she was told something much more important.

  The fleet chief brought Cheng Xin into the dinghy. There wasn’t much room inside, just enough for four people. As soon as the two of them sat down, half of the spherical hull—the part facing them—became transparent, so that they seemed to be sitting inside the helmet of a gigantic space suit. This type of dinghy was chosen in part for its open field of view.

  Modern spacecraft no longer had physical controls—the controls were holographic projections—thus, the interior of the hull was completely empty. If a Common Era person came here for the first time, he or she would think this was an empty shell with nothing inside. But Cheng Xin immediately noticed three unusual objects, clearly new additions. These were three circles attached to the hull above the transparent part, colored green, yellow, and red, reminding her of traffic lights from the past. The fleet chief explained:

  “These three lights are controlled by Sophon. Your meeting will be monitored throughout by the Trisolarans. As long as they believe the contents of your conversation are acceptable, the green light will stay on. If they wish to warn you about topics verging on the unacceptable, the yellow light will be lit.”

  The fleet chief paused, and only after a long while, as though he had to prepare himself, did he explain the red light.

  “If they think you’re being given information you may not receive, the red light will be lit.”

  He turned around and pointed to the nontransparent part of the hull. Cheng Xin saw a small metallic attachment resembling a weight used on an ancient balance.

  “This bomb is controlled by Sophon. It will detonate three seconds after the red light turns on.”

  “What will be destroyed?” Cheng Xin asked. She wasn’t thinking of herself.

  “Just our side of the meeting. You don’t need to worry about Tianming’s safety. Sophon has made it clear that even if the red light is lit, only this dinghy will explode; Tianming will not be harmed in any way.

  “The red light may be lit during your conversation. However, even if the meeting completes successfully, the Trisolarans may decide, upon review of the conversation record, to turn on the red light. I’m going to tell you the most important part now—” The fleet chief paused again.

  Cheng Xin’s gaze remained placid. She nodded at him, encouraging him to continue.

  “You must remember that the lights will not be used as a traffic light. They may not warn you before deciding that you’ve stepped over the line. The green light may change to a red light immediately, without going through the yellow light.”

  “All right. I understand.” Cheng Xin’s voice was soft, like a passing breeze.

  “Other than the contents of the conversation, Sophon may also light the red light if she discovers recording equipment on the dinghy or some means of transmitting your conversation outside the dinghy. You may rest easy on this point. We’ve examined this dinghy repeatedly for recording devices, and we’ve eliminated all communications equipment. The navigation system isn’t even capable of keeping a log. Your entire journey will be directed by the shi
pboard AI system, which will not communicate with the outside world prior to your return. Dr. Cheng, please think through what I’ve said to be sure you understand the implications.”

  “If I don’t return, then you get nothing.”

  “I’m glad you see. This is what we want to emphasize. Do as they say, and only talk about private matters between the two of you. Do not mention other topics, not even through hints or metaphors. At all times, remember that if you don’t return, Earth gets absolutely nothing.”

  “But if I do as you say and return, Earth will still get nothing. That is not what I want.”

  The fleet chief looked at Cheng Xin, but not directly, only at her reflection on the transparent hull. Her image was superimposed against the universe, and her lovely eyes serenely reflected the stars. He seemed to see her as the center of the universe, the stars revolving around her. Once again, he forced himself to not dissuade her from taking a risk.

  Instead, he pointed behind him. “This is a miniature hydrogen bomb. Under the old measurement system you’re familiar with, its yield is about five kilotons. If... it really has to happen, everything will end in a flash. You will not feel it.”

  Cheng Xin smiled at the fleet chief. “Thank you. I understand.”

  Five hours later, the dinghy began its journey. The hypergravity of 3G pressed Cheng Xin against the seat—this was the limit on the acceleration an individual without special training could bear. In a window that showed what was behind her, she saw the immense hull of the terminal station reflecting the fire from her dinghy’s drive. The tiny dinghy appeared as a spark flying out of a furnace, but the terminal station rapidly shrank, and soon turned into a tiny dot. Only the Earth itself, still imposing, took up half the sky.

  The special team had told Cheng Xin again and again that the flight itself would be routine, no more special than the airplane rides she used to take. The distance between the terminal station and the Lagrangian point was about 1.5 million kilometers, or one hundredth of an astronomical unit. This was considered an extremely short spaceflight, and the craft she rode in was well suited for such brief trips. Cheng Xin recalled that three centuries ago, one of the things that had lured her into aerospace engineering was a great accomplishment by humankind during the twentieth century: fifteen men had managed to step onto the moon. Their voyage had only been a fifth as long as the journey she was about to undertake.

  Ten minutes later, Cheng Xin got to see a sunrise in space. The Sun slowly rose over the curved edge of the Earth. From such distance, the waves over the Pacific were invisible, and the ocean was like a mirror reflecting sunlight. The clouds appeared as soapy foam over the mirror. From this vantage point, the Sun appeared much smaller than the Earth, like a shining golden egg being birthed by this dark blue world. By the time the Sun had completely emerged from the curved horizon, the side of the Earth facing the Sun turned into a giant crescent. The crescent was so bright that the rest of the Earth merged into dark shadow, and the Sun and the crescent seemed to form a giant symbol hovering in space. Cheng Xin thought of the mark as symbolizing rebirth.

  She knew that this could very well be her last sunrise. In the upcoming meeting, even if she and Tianming faithfully followed the rules around their conversation, there was a possibility that the distant Trisolarans would not permit her to live, and she wasn’t interested in following the rules at all. But she thought everything was perfect; she had no regrets.

  As the dinghy progressed, the lit portion of the Earth expanded. Cheng Xin saw the outlines of the continents, and easily picked out Australia. It resembled a dry leaf floating in the Pacific. The continent was emerging from the shadow, and the terminator was right in the middle of the continent. It was morning in Warburton, and she thought of the desert sunrise seen by Fraisse from the edge of the wood.

  Her dinghy swept over the Earth. By the time the curved horizon had finally disappeared over the edge of the viewport, acceleration stopped. As the hypergravity disappeared, Cheng Xin felt as though a pair of arms hugging her tightly had relaxed. The dinghy coasted toward the Sun, and the light from the Sun overwhelmed all the stars. The transparent hull adjusted and dimmed until the Sun was a disc whose brightness was no longer blinding. Cheng Xin reached out to adjust it even more, until the Sun resembled the full moon. She still had six more hours to travel. She drifted in weightlessness, drifted in the moonlight-like sun.

  Five hours later, the dinghy turned 180 degrees and the engine came to life for deceleration. As the dinghy turned, Cheng Xin saw the Sun gradually move away, and then the stars and the Milky Way swept past her vision like a long scroll. By the time the dinghy stopped, the Earth was once again at the center of her view. It now looked about as big as the moon from the surface of the Earth, and the immensity it had displayed a few hours ago was gone. Now it looked fragile, like a fetus floating in blue amniotic fluid about to emerge from the warm womb and be exposed to the frigidity and darkness of space.

  With the engine turned on, gravity returned to embrace Cheng Xin. The deceleration lasted about half an hour before the drive started to pulse for precision position maneuvers. Finally, gravity disappeared again, and everything became quiet.

  This was the Lagrangian point. Here, the dinghy was a satellite of the Sun, orbiting in synch with the Earth.

  Cheng Xin glanced at her watch. The voyage had been planned very well. She still had ten minutes before the meeting. The space around her was empty, and she struggled to empty her mind as well. She was preparing herself for the task of memorization: The only thing that could retain anything from the meeting was her brain. She had to turn herself into an emotionless audio and video recorder so that during the next two hours she could remember as much as possible of what she saw and heard.

  She imagined the corner of space she happened to be in. Here, the Sun’s gravity overcame the Earth’s, reaching balance, so this place held an extra measure of emptiness compared to other spots in space. She was in this emptiness of zero, a lonely, independent presence that had no connections to any other part of the cosmos.... In this way, she managed to drive her complicated emotions out of her consciousness, until she achieved the blank, transcendent state she wanted.

  Not too far ahead of the dinghy, a sophon began to unfold into lower-dimensional space. Cheng Xin saw a sphere about three or four meters in diameter appear a few meters in front of the dinghy. The sphere blocked the Earth and took up most of her view. The surface of the sphere was perfectly reflective, and Cheng Xin could clearly see the reflection of her dinghy and herself. She wasn’t sure if the sophon had been lurking inside the dinghy or if it had just arrived.

  The reflection on the surface of the sphere disappeared as the sphere turned translucent, like a ball of ice. At times, Cheng Xin thought it resembled a hole dug in space. Next, countless snowflake-like bright spots floated up from deep within the sphere, forming a flickering pattern on the surface. Cheng Xin recognized that this was just white noise, like the random snow seen on a television screen when there was no reception.

  The white noise lasted about three minutes, and then a scene from several light-years away took its place. It was crystal clear, with no signs of distortion or interference.

  Cheng Xin had entertained countless guesses as to what she would see. Maybe she would only have voice and text; maybe she would see a brain floating in nutrient fluid; maybe she would see Yun Tianming whole. Though she believed that this last possibility was practically impossible, she tried to imagine the environment Tianming would be living in. She thought of innumerable scenarios, but none was like what she actually saw.

  A golden field of wheat bathed in sunlight.

  The field was about a tenth of an acre. The crop looked to be doing well, and it was time for the harvest. The soil appeared a bit eerie: pure black, and the particles sparkled in the sunlight like innumerable stars. A common shovel was stuck into the black soil next to the field of wheat. It looked perfectly ordinary, and even the handle appeared to be made
of wood. A straw hat woven from wheat stalks hung from the top of the shovel—it looked old and well used, and loose stalks stuck out of the worn rim. Behind the wheat field was another field planted with something green, probably vegetables. A breeze passed through, and the wheat rippled.

  Above this dark-soiled scene was an alien sky—a dome, to be exact, formed of a knotty mess of intertwined pipes, some thick, some thin, all of which were leaden gray in color. Among the thousands of pipes, two or three glowed red. The light from them was very bright, making them appear as incandescent filaments. The exposed portions of these pipes illuminated the fields and apparently provided the source of energy for the crops. Each illuminated pipe only shone briefly before dimming, to be replaced by another pipe that lit up elsewhere. At each moment, two or three pipes were on. The shifting lights caused the shadows in the field to shift constantly as well, as though the sun were weaving in and out of clouds.

  Cheng Xin was taken aback by the chaotic arrangement of the pipes. It wasn’t the result of carelessness; on the contrary, to create this kind of utter chaos required great effort and design. The arrangement seemed to find even the hint of a pattern to be taboo. This suggested an aesthetic utterly at odds with human values: Patterns were ugly, but the lack of order was beautiful. Those glowing pipes gave the entire knotty mess a kind of liveliness, like sunlight glanced through clouds. Cheng Xin even wondered whether the arrangement was meant to be an artistic representation of the sun and clouds. But the next moment, she felt the arrangement evoking a giant model of the human brain, and the flickering, glowing pipes represented the formation of each neural feedback loop....
