“They know how to disable the droplets!” someone cried out.
Captain Morovich could think of only one thing. Like Hunter a few minutes ago, he didn’t hesitate to push the button on his watch. The error message appeared in a red information window that appeared midair:
Failure: The self-destruct module has been dismantled.
The captain dashed out of the combat center and headed for the stern. The other officers followed.

The first person from Gravity to arrive at the gravitational wave transmission control room was Old Hunter. Though he had no authorization to enter the cabin, he wanted to try to break the link between the controller and the antenna. This would at least temporarily disable the transmission system until he figured out how to destroy the controller itself.
But someone was already there, examining the control cabin.
Hunter took out his sidearm and aimed it at the man. He wore the uniform of a sublieutenant on Gravity, not the uniform dating from the Doomsday Battle that Hunter expected to see—the man had stolen it. Hunter recognized him from the back. “I knew Commander Devon was right.”
Lieutenant Commander Park Ui-gun, head of the marines on Blue Space, turned around. He looked no older than thirty, but his face showed that he had endured experiences that no one aboard Gravity could imagine. He was slightly surprised. Perhaps he didn’t expect anyone here so soon; perhaps he didn’t expect to see Hunter. Yet, he remained calm. With both hands half raised, he said, “Please let me explain—”
Old Hunter wasn’t interested in an explanation. He didn’t want to know how this man had boarded Gravity, and didn’t even want to know if he was a man or a ghost. Whatever the facts, the situation was too dangerous. All he wanted was to destroy the transmission controller unit. It was his only goal in life, and this man from Blue Space stood in the way. He squeezed the trigger.
The bullet struck Park in the chest, and the impact threw him against the cabin door. Hunter’s gun was loaded with special bullets designed for use inside the ship: They wouldn’t damage the bulkheads or other equipment, but they also weren’t as deadly as laser beams. Some blood oozed out of the wound, but Park managed to stay erect in the weightlessness and reached into his bloody uniform for his own weapon. Hunter shot again, and there was a fresh wound in Park’s chest. More blood oozed out, floating in the gravity-less air. Finally, Hunter took aim at Park’s head, but he didn’t get a chance for the third shot.
This was the scene that greeted Captain Morovich and the other officers when they arrived: Hunter’s gun was floating far away from him. The old cook’s body was stiff, his open eyes showing only white, his limbs twitching. Blood erupted forth from his mouth like a fountain, coagulating into spheres of various sizes drifting around him in a cloud. In the middle of the bloody, translucent spheres was a dark red object about the size of a fist, dragging two tubes behind it like tails.
Rhythmically, it pulsed in midair, and with every pulse, more blood was squeezed out of its two tubular tails. The object propelled itself forward like a crimson jellyfish swimming through the air.
It was Hunter’s heart.
During the struggle a few moments earlier, Hunter had slammed his right hand against his chest, and then, desperately, torn open his clothes. Thus, his bare chest lay revealed, and everyone could see that the skin was perfect, with not a single scratch.
“He can be saved if we get him into surgery right away,” Sublieutenant Park said with some difficulty, his voice very hoarse. Blood continued to spill from the two wounds in his chest. “Good thing that doctors don’t need to open his chest to reattach his heart anymore.… Don’t move! It’s as easy for them to pluck out your heart or brain as it is for you to pick an apple dangling from a branch in front of you. Gravity has been captured.”
Fully armed marines rushed in from another corridor. Most of them wore the dark blue lightweight space suits dating from before the Doomsday Battle—apparently they were all from Blue Space. All the marines were equipped with powerful laser assault rifles.
Captain Morovich nodded at his officers. Without speaking, they tossed their weapons away. Blue Space had ten times more people than Gravity, and just their detachment of marines numbered more than a hundred. They could easily control Gravity.
There was nothing beyond belief anymore. Blue Space had turned into a supernatural warship wielding magic. The crew of Gravity again experienced the shock they had last suffered during the Doomsday Battle.
* * *
More than fourteen hundred people floated in the middle of Blue Space’s spherical great hall. The largest portion, over twelve hundred, belonged to the crew of Blue Space. Sixty years ago, the officers and enlisted men of this ship had also lined up here to accept Zhang Beihai’s command, and most of them were still here. Since only a few individuals needed to be awake and on duty for regular cruising, the crew had aged only three to five years on average. They hadn’t experienced the bulk of the intervening years, and the searing flames of the dark battles and the cold funerals held in space remained fresh in their minds. The remainder belonged to the one-hundred-strong crew of Gravity. The two crews—one large, one small, wearing distinct uniforms and suspicious of each other—gathered into two clusters far apart from each other.
Before the two crews, the senior officers of the two ships were mixed together. Captain Chu Yan of Blue Space drew the most attention. He was forty-three, but looked younger, and he was the model of the scholarly military officer. Refined and calm in his speech and mannerisms, he even gave off a hint of shyness. But on Earth, Chu Yan was already a figure of legend. During the dark battles, he was the one who had given the order to turn the interior of Blue Space into a vacuum, thereby preventing the crew from death in the infrasonic nuclear bomb attack. Even now, public opinion on Earth remained divided as to whether Blue Space’s actions during the dark battle should be classified as self-defense or murder. After the founding of dark forest deterrence, he was the one who had resisted the heavy pressure of majority opinion aboard and delayed Blue Space’s return, thus giving the ship sufficient time to escape after the warning from Bronze Age. There were many other rumors concerning Chu Yan. For instance, when Natural Selection had chosen to defect and escape the Doomsday Battle, he was the only captain to ask to give chase. Some claimed that he had a different purpose in mind, wanting to hijack Blue Space and escape along with Natural Selection. Of course, those were just rumors.
“Almost everyone from the two ships is gathered here,” said Chu Yan. “Although much still divides us, we prefer to think of everyone as belonging to the same world, formed from Blue Space and Gravity. Before we plan the future of our world together, we need to take care of an urgent matter.”
A large holographic display window appeared midair, showing somewhere in space where the stars were sparse. In the middle of the region was a faint white fog, and the fog was etched with several hundred straight parallel lines, like brush bristles. The white lines had clearly been enhanced and stood out in the image. In the past two centuries, these “brushes” had become very familiar to people, and some brands even used them in their logos.
“These trails were observed eight days ago in the stellar dust cloud near Trisolaris. Please pay attention to the video.”
Everyone stared at the image, and the trails could be seen to grow in the fog.
“How many times have you sped up the video?” an officer from Gravity asked.
“It’s not sped up at all.”
The crowd grew agitated, like a forest struck by a sudden rainstorm.
“By a rough estimate … these ships are moving at close to the speed of light,” Captain Morovich of Gravity said. His voice was very tranquil. He had experienced too many incredible sights in the last two days.
“That’s right. The Second Trisolaran Fleet is heading for Earth at lightspeed, and should arrive in four years.” Chu Yan looked at Gravity’s crew with caring eyes, as though sorry that he
had to deliver this news. “After you left, the Earth sank into a dream of universal peace and prosperity, and completely misjudged the situation. Trisolaris has been waiting patiently, and now they’ve finally seized their chance.”
“How do we know this is authentic?” someone from Gravity called out.
“I can attest to it!” said Guan Yifan. Among the small gathering in front of the crews, he was the only one not in a military uniform. “My observatory had also detected the same trails. However, since I was focused on large-scale cosmological observations, I didn’t pay much attention to them. But I’ve gone back and retrieved the recorded data. The Solar System, the Trisolaran system, and our ships form a scalene triangle. The side between the Solar System and the Trisolaran system is the longest. The side between the Solar System and us is the shortest. The side going from the Trisolaran system to us is in between. In other words, we are closer to the Trisolaran system than the Solar System is to the Trisolaran system. About forty days from now, the Earth will also detect the trails we’re seeing.”
Chu Yan took over. “We believe that something has already taken place on the Earth. More specifically, it happened about five hours ago, when the droplets attacked our two ships. Based on information provided by Gravity, that was the scheduled time for the Swordholder to transfer his authority to his successor. This was the opportunity Trisolaris had been waiting for for half a century. The two droplets had clearly been given orders before entering the blind zone. This was a long-planned, coordinated attack.
“I must conclude that the peace brought by dark forest deterrence has been breached. There are only two possibilities: The gravitational wave universal broadcast has been initiated, or it hasn’t.”
Chu Yan tapped in the air and brought up Cheng Xin’s picture on the holographic display. This picture of the new Swordholder had also just been obtained from Gravity. Cheng Xin stood in front of the UN Secretariat Building, holding a baby. Her picture had been blown up to be as large as the “brush” bristles, and the contrast between the two images couldn’t be sharper. The basic color scheme of space was black and silver—the depth of space and the cold light of the stars. But Cheng Xin resembled a Madonna from the East. A warm, golden glow bathed her and the baby, giving all those present the feeling of being close to the sun, a sensation that they had missed for half a century.
“We believe the latter scenario is true,” Chu Yan said.
“How did they pick such a person to be Swordholder?” someone from Blue Space asked.
Captain Morovich answered. “It’s been sixty years since you left home, and fifty for us. Everything on Earth has changed. Deterrence made a comfortable cradle, and as humanity napped inside, it regressed from an adult to a child.”
“Don’t you know that there are no more men on Earth?” someone from Gravity shouted.
“Humans on Earth lost the ability to maintain dark forest deterrence,” Chu Yan said. “We had planned to capture Gravity and re-establish dark forest deterrence. But we’ve just found out that due to decay in the antenna, the ability to broadcast gravitational waves will only last two more months. Believe me, this has been an incredible blow to all of us. We have only one choice: immediately activate the universal broadcast.”
The crowd erupted. Next to the view of cold space showing the lightspeed trails of the Trisolaran Fleet, Cheng Xin gazed at them, full of love. The two images portrayed their two choices.
“Are you really willing to commit mundicide?” Captain Morovich demanded.
Chu Yan maintained his serenity against the chaos. Ignoring Captain Morovich, he spoke to the crowd. “For us, initiating the broadcast is meaningless. Neither the Earth nor Trisolaris can catch us now.”
Everyone understood this. The sophons were permanently severed from home, and the droplets had been destroyed. Earth and Trisolaris thus had no way to trace them. In the vast, deep space beyond the Oort Cloud, even Trisolaran ships operating at lightspeed would never be able to find two motes of dust.
“Then you’re just seeking revenge!” an officer from Gravity said.
“Vengeance against Trisolaris is our right. They must pay for the crimes they’ve committed. In war, it is right and just to destroy one’s enemies. If my deduction is correct, humankind’s gravitational wave transmitters have all been destroyed, and the Earth is now under occupation. It’s very likely that the genocide of the human race is underway.
“Activating the universal broadcast would give the Earth one last chance. If the location of the Solar System is revealed, it would no longer have any value to Trisolaris because it could be destroyed at any moment. This would force the Trisolarans to leave the Solar System, and their lightspeed fleet would have to turn away. We may be able to save the human race from immediate annihilation. To give them more time, our broadcast will include only the location of Trisolaris.”
“That’s the same as revealing the Solar System! It’s too close.”
“We all know that, but hopefully this will give the Earth a little more time and allow more humans to escape. Whether they will choose to do so is up to them.”
“You’re talking about destroying two worlds!” said Captain Morovich. “And one of them is our mother. This decision is the Last Judgment. It cannot be made so lightly.”
“I agree.”
A holographic rectangular red button about a meter long appeared between the two existing information windows. Below it was a number: 0.
Chu Yan continued. “As I said earlier: together, we are one world. Everyone in this world is an ordinary person, but fate has put us into the position of making the last judgment about two worlds. This decision must be made, but a single person or even a few persons shouldn’t make it. This will be the decision of the whole world through a referendum. All in favor of broadcasting the location of Trisolaris to the universe, please press this red button. All opposed or abstaining, do nothing.
“Right now, the total number of people aboard Blue Space and Gravity, including all present and those on duty, is one thousand four hundred and fifteen. If the ayes reach or exceed two-thirds of the total, nine hundred forty-four, the universal broadcast will begin immediately. Otherwise, we will never activate the broadcast and let the antenna decay and fail.
“Begin.”
Chu Yan turned and pressed the giant red button hovering in air. The button flashed, and the number below it turned from 0 to 1. Next, the two vice-captains of Blue Space pressed the buttons in quick succession. The tally went up to 3. Then the other senior officers of Blue Space, followed by the junior officers and enlisted men, filed past the red button in a long line, pressing the button again and again.
As the red button flashed, the tally crept up. These were the final beats of the heart of history, the final steps taken toward the terminal point.
When the number reached 795, Guan Yifan pressed the button. He was the first person from Gravity to support the broadcast. After him, several more officers and enlisted men from Gravity also pressed the button.
Finally, the number reached 943, and a large line of text appeared above the button:
The next affirmative vote will activate the universal broadcast.
The next person to vote was an enlisted man. Many others were lined up behind him. He placed his hand above the button, but didn’t push. He waited until the ensign behind him put his hand on his, and then more hands joined theirs in a thick stack.
“Please wait,” Captain Morovich said. He drifted over and, as everyone watched, placed his hand atop the pile.
Then dozens of hands moved together, and the button flashed one more time.
Three hundred fifteen years had passed since that morning in the twentieth century when Ye Wenjie had pushed another red button.
The gravitational wave broadcast began. Everyone present felt a strong tremor. The feeling seemed to come not from without, but from within each body, as though every person had become a vibrating string. This instrument of death played for only twel
ve seconds before stopping, and then everything was silent.
Outside the ship, the thin membrane of space-time rippled with the gravitational waves, like a placid lake surface disturbed by a night breeze. The judgment of death for both worlds spread across the cosmos at the speed of light.
Post-Deterrence Era, Year 2
The Morning After the Great Resettlement, Australia
The noises around her quieted down, and Cheng Xin could hear voices coming from the information window over the city government tent. She could tell one of the voices belonged to Sophon, in addition to two others. But she was too far away to make out exactly what they said. She thought their voices cast a spell because the noises around her faded and finally disappeared. The world seemed to be frozen.
Then a tsunami erupted around her, and Cheng Xin trembled. She had been blind for a while, and the images of the real world in her mind were being squeezed out bit by bit by illusions. The sudden bedlam made her feel as if the Pacific had risen up all around her and swallowed Australia.
It took a few seconds before she understood that the crowd was cheering. What’s there to cheer about? Has everyone gone mad? The clamor did not subside, though it was eventually replaced by speech. So many were talking at once it was as if, after the continent had been flooded, a storm lashed the surface of the sea. She could not tell what anyone was saying in the tumult.
But she picked out “Blue Space” and “Gravity” more than once.
Her hearing gradually recovered its acuity, and she noticed a faint sound amidst the general commotion: footsteps in front of her. She felt someone stop there.
“Dr. Cheng Xin, what is wrong with your eyes? Can you not see?” Cheng Xin felt movements disturbing the air. Perhaps the man was waving his hands before her eyes. “The mayor sent me for you. We’re going home, back to China.”
