Death's End

The hunt for Blue Space was the only undertaking where Earth and Trisolaris truly shared the same goal, because this lone ship heading into deep space was a threat to both worlds. During the Earth’s attempt to lure back the two ships that had survived the dark battles, Blue Space had learned the dark forest nature of the universe. If Blue Space someday mastered the ability to broadcast to the universe, the consequences would be unimaginable. The hunt thus received the total cooperation of Trisolaris. Before entering the blind region, the sophons had provided Gravity with a real-time, continuous view of the interior of the prey.

Over the decades, Hunter was promoted from petty officer second class to petty officer first class, and then, as a special promotion, became a commissioned officer. Starting as an ensign, he was promoted all the way up to lieutenant. But even at the end, he never had the formal authorization to view the live feed of the interior of Blue Space transmitted by the sophons. However, he did possess the backdoor codes to all the ship’s systems, and he often viewed a palm-sized version of the video feed in his own cabin.

He saw that Blue Space was a completely different society from Gravity. It was militaristic, authoritarian, and governed by strict codes of discipline. Everyone devoted their spiritual energy to the collective. The first time he saw Reiko was two years after the start of the chase. He was instantly smitten by this East Asian beauty. He would watch her for hours every day, and sometimes even thought he knew her life better than he knew his own. But a year later, Reiko went into hibernation, and the next time she woke up for duty was thirty years later. She was still young, but Hunter was already near sixty.

On Christmas Eve, after a wild party, he returned to his cabin and brought up the live feed from Blue Space. The view began with a diagram of the complex overall structure of the ship. He tapped the location of the navigation center, and the view zoomed in to show Reiko on duty. She was looking at a large holographic star map, on which a bright red line traced the course of Blue Space. Behind it was a white line that almost coincided with the red line, indicating the path taken by Gravity. Hunter noticed that the white line deviated slightly from Gravity’s true course. Right now, the two ships were still a few thousand AU apart. At this distance, it was difficult to track a target as small as a spaceship with certainty. The white line probably only indicated their best guess, although the estimate of the distance between the two ships was pretty accurate.

Hunter zoomed in some more. Reiko suddenly turned to face him, and, with a smile that made his heart clench, said, “Merry Christmas!” Hunter knew that Reiko wasn’t talking to him, but to all those hunting her ship. She was aware that she was being watched by sophons, though she couldn’t see her pursuers. Regardless, this was one of the happiest moments of Hunter’s life.

Because the crew aboard Blue Space was large, Reiko’s duty cycle didn’t last long. One year later, she entered hibernation again. Hunter looked forward to the day he would meet Reiko face-to-face, when Gravity finally caught up to Blue Space. Sadly, he knew that he would be almost eighty by the time that happened. He hoped he would get to tell her he loved her and then watch as she was taken away for trial.

For half a century, Hunter faithfully carried out his mission. He remained alert for any unusual conditions aboard the ship, preparing in his mind action plans for various crises. But the mission didn’t really put too much pressure on him. He knew that another form of insurance, utterly reliable, accompanied Gravity. Like many others, he often watched the droplets cruising at a distance from the portholes. But the droplets, in his eyes, held another meaning. If anything unusual occurred on Gravity, especially if there were signs of a mutiny or illegal attempts to seize control of the gravitational wave transmission system, he knew that the droplets would destroy this ship. They could move far faster than he—a droplet could accelerate from a few thousand meters away and reach a target in no more than five seconds.
