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.
