Death's End

This should have been her fate. It would have been the best ending for a Swordholder who had given up the power to deter.

The red glow at the bottom of the crater attracted Cheng Xin. Just one more step, and she would achieve the release that she desired. As waves of heat buffeted her face, she stared at the dim red pool, mesmerized, until peals of laughter from behind her shook her out of her musing.

She turned around. In the flickering sunlight filtered by the smoke, a slender figure approached her. She didn’t recognize the newcomer until she was very close: Sophon.

Other than the pale, lovely face, the robot looked completely different from the last time Cheng Xin had seen her. She was dressed in desert camouflage, and her hair, once tied up in a neat bun decorated with flowers, had been cut in a short and efficient style. Around her neck was the black scarf of a ninja, and on her back was strapped a long katana. She looked valiant and heroic, but the extreme femininity that she exuded had not vanished completely: Her postures and movements were still soft and gentle like water, but now they were also suffused with a glamorous air of killing and death, like a pliant but fatal noose. Even the heat spilling from the crater could not dispel the chill she brought.

“You acted just as we anticipated,” Sophon said, sneering. “Don’t be too hard on yourself. The fact is that humankind chose you, and they chose this result. Out of all the members of the human race, you’re the only innocent.”

Cheng Xin’s heart jumped. She didn’t feel comforted, but she had to admit that this lovely devil had a power that penetrated her soul.

Cheng Xin saw AA approach. She had apparently found out or guessed what had really happened. AA’s eyes burned with fury as she stared at Sophon; she picked up a rock from the ground with both hands and smashed the back of Sophon’s skull with it. But Sophon turned around and brushed the rock away like a mosquito. AA cursed at Sophon using every profane word she could think of, and went for another rock. Sophon unsheathed the katana on her back, easily pushing off the pleading Cheng Xin with her other hand, and twirled the katana. It sliced through the air, faster than the blades of an electric fan, whining loudly. When she stopped, strands of AA’s hair drifted down around her head. AA stood frozen in place, terrified, her shoulders hunched.

Cheng Xin remembered that she had seen Sophon’s katana in that eastern leaf-house shrouded in fog and cloud. Back then, it, and two shorter swords, had rested on a refined wooden stand next to the tea table, looking more decorative than deadly.

“Why?” Cheng Xin muttered, as if asking herself.

“Because the universe is not a fairy tale.”

Rationally, Cheng Xin understood that, had the balance maintained by deterrence continued, the brighter future belonged to humankind, not Trisolaris. But in her subconscious, the universe remained a fairy tale, a fairy tale about love. Her biggest mistake was not looking at the problem from the perspective of the enemy.

From Sophon’s gaze, Cheng Xin finally understood why she had been kept alive.

As the gravitational wave broadcast system had been destroyed and the sun’s ability to amplify radio waves had been suppressed, a living Cheng Xin posed no threat. On the other hand, in the unlikely event that humans still possessed some other method of broadcasting to the universe unknown to Trisolaris, eliminating the Swordholder might cause others to activate the broadcast. As long as the Swordholder was alive, however, the probability of that happening was virtually nil: Others would have a reason and excuse to shirk their responsibility.

Instead of the deterrer, Cheng Xin had been turned into a safety shield. The enemy had seen through her completely.

She was a fairy tale.

“Don’t celebrate too early,” AA said to Sophon, having recovered some of her courage. “We still have the spaceship Gravity.”

Sophon returned the katana to its sheath on her back in a single, smooth motion. “Foolish girl, Gravity has been destroyed. It happened an hour ago, when the handover occurred a light-year away. I regret that I can’t show you the wreckage because the sophons are in a blind zone.”

The Trisolarans had been planning and preparing for this moment for a long time. The exact time for the handover had been determined five months ago, before the sophons accompanying Gravity had entered the blind zone. The two droplets with Gravity had already received the order to destroy the ship at the moment of the handover.

“I’m leaving,” said Sophon. “Please convey to Dr. Luo Ji the deepest respect of all of Trisolaris. He was a powerful deterrer, a great warrior. Oh, and if you get the chance, also give Mr. Thomas Wade our regrets.”

Cheng Xin looked up, surprised.
