YE: I started the fire, but I couldn't control how it burnt.

INTERROGATOR: You had a plan to eliminate the Adventists from within the ETO, and you even began to implement this plan. But Judgment Day is the core base and command center for the Adventists, and Mike Evans and other Adventist leaders usually reside there. Why didn't you attack the ship first? Most of the armed forces of the Redemptionists are loyal to you, and you should have enough firepower to sink it or capture it.

YE: It's because of the messages from the Lord that they intercepted. All those messages are stored in the Second Red Coast Base, on some computer on Judgment Day. If we attacked that ship, the Adventists could erase all the messages when they realized that loss was imminent. Those messages are too important for us to risk losing them. For Redemptionists, losing those messages would be as if Christians lost the Bible or Muslims lost the Koran. I think you are faced with the same problem. The Adventists are holding the Lord's messages hostage, and that is why Judgment Day has remained unmolested so far.

INTERROGATOR: Do you have any advice for us?

YE: No.

INTERROGATOR: You also call Trisolaris your "Lord." Does this mean that you've also developed religious feelings for Trisolaris like the Redemptionists? Are you already a follower of the Trisolaran faith?

YE: Not at all. It's just a habit.... I do not wish to discuss it further.

INTERROGATOR: Let's get back to those intercepted messages. Maybe you don't know the exact contents, but surely you must have heard rumors of some of the details?

YE: Probably only baseless rumors.

INTERROGATOR: Such as?

YE:...

INTERROGATOR: Did Trisolaris transfer certain technologies to the Adventists, technologies more advanced than current human technology?

YE: Not likely. Because such technology would risk falling into your hands.

INTERROGATOR: One last question, and also the most important: Until now, has Trisolaris sent only radio waves to the Earth?

YE: Almost true.

INTERROGATOR: Almost?

YE: The current Trisolaran civilization is capable of s.p.a.ce travel at one-tenth the speed of light. This technology leap occurred a few decades ago in Earth years. Before that point, their maximum speed had hovered around one-thousandth the speed of light. The tiny probes that they sent to the Earth have not even completed one-hundredth of the journey between there and here.

INTERROGATOR: Then I have a question. If the Trisolaran Fleet that had been launched is capable of flight at one-tenth the speed of light, it should take only forty years to reach the solar system. So why do you say that it would take more than four hundred years?

YE: Here's the thing. The Trisolaran Interstellar Fleet is composed of incredibly ma.s.sive s.p.a.ceships. Accelerating them is a slow process. One-tenth the speed of light is only their maximum speed, but they cannot cruise at this speed for long before decelerating as they approach the Earth. Also, the source of propulsion for the Trisolaran ships is matter-antimatter annihilation. In front of each ship is a large magnetic field shaped like a funnel to collect antimatter particles from s.p.a.ce. This collection process is slow, and only after a long wait can it gather enough antimatter to allow the ship to accelerate for a brief period. Thus, the fleet's acceleration occurs in spurts, interspersed by long periods of coasting to collect fuel. This is why the time it takes the Trisolaran Fleet to reach the solar system is ten times longer than the flight time of a small probe.

INTERROGATOR: Then what did you mean by "almost" just now?

YE: We're talking about the speed of s.p.a.ce flight within a certain context. Outside this context, even backward human beings are capable of accelerating certain objects to close to the speed of light.

INTERROGATOR: (a pause) By "context," do you mean at the macro scale? At a micro scale, humans can already use high-energy particle accelerators to speed up subatomic particles to near the speed of light. These particles are the "objects" you meant, correct?

YE: You're very clever.

INTERROGATOR: (points to his earpiece) I have the world's foremost scientists behind me.

YE: Yes, I meant subatomic particles. Six years ago, in the distant Trisolaran stellar system, Trisolaris accelerated two hydrogen nuclei to near the speed of light and shot them toward the solar system. These two hydrogen nuclei, or protons, arrived at the solar system two years ago, then reached the Earth.

INTERROGATOR: Two protons? They only sent two protons? That's almost nothing.

YE: (laughs) You also said "almost." That's the limit of Trisolaran power. They can only accelerate something as small as a proton to near the speed of light. So over a distance of four light-years, they can only send two protons.

INTERROGATOR: At the macroscopic level, two protons are nothing. Even a single cilium on a bacterium would include several billion protons. What's the point?

YE: They're a lock.

INTERROGATOR: A lock? What are they locking?

YE: They are sealing off the progress of human science. Because of the existence of these two protons, humanity will not be able to make any important scientific developments during the four and a half centuries until the arrival of the Trisolaran Fleet. Evans once said that the day of arrival of the two protons was also the day that human science died.

INTERROGATOR: That's ... too fantastic. How can that be?

YE: I don't know. I really don't know. In the eyes of Trisolaran civilization, we're probably not even primitive savages. We might be mere bugs.

It was near midnight by the time w.a.n.g Miao and Ding Yi walked out of the Battle Command Center. They had been invited to listen to Ye's interrogation due to w.a.n.g's involvement in the case and Ding Yi's connection to Ye's daughter.

"Do you believe what Ye Wenjie said?" w.a.n.g asked.

"Do you?"

"Many things that have happened recently are incredible. But for two protons to block all progress of human science? That seems..."

"Let's focus on one thing first. The Trisolarans were able to shoot two protons at the Earth from four light-years away and they both reached the target! That accuracy is incredible! There are numerous obstacles between there and here: interstellar dust, for example. And both the solar system and the Earth are moving. It would require more precision than shooting a mosquito here from Pluto. The shooter is beyond imagination."

w.a.n.g's heart clenched when he heard "shooter." "What do you think this means?"

"I don't know. In your impression, what do subatomic particles such as neutrons and protons look like?"

"They would just look like a point. Though the point has internal structure."

"Luckily, the image in my head is more realistic than yours." As Ding spoke, he tossed his cigarette b.u.t.t away. "What do you think that is?" He pointed at the b.u.t.t.

"A cigarette filter."

"Good. Looking at that tiny thing from this distance, how would you describe it?"

"It's practically just a point."

"Right." Ding walked over and picked up the b.u.t.t. In front of w.a.n.g's eyes he tore it open and revealed the yellowed spongy material inside. w.a.n.g smelled burnt tar. Ding continued, "Look, if you spread this little thing open, the adsorbent surface area can be as large as a living room." He tossed the filter away. "Do you smoke pipes?"

"I no longer smoke anything."

"Pipes use another type of more advanced filter. You can get one for three yuan. The diameter is about the same as a cigarette filter, but it's longer: a small paper tube filled with active charcoal. If you take out all the active charcoal, it will look like a little pile of black particles, like mouse droppings. But added together, the adsorbent surface formed by the tiny holes inside is as large as a tennis court. This is why active charcoal is so adsorbent."

"What are you trying to say?" w.a.n.g asked, listening intently.

"The sponge or active charcoal inside a filter is three-dimensional. Their adsorbent surfaces, however, are two-dimensional. Thus, you can see how a tiny high-dimensional structure can contain a huge low-dimensional structure. But at the macroscopic level, this is about the limit of the ability for high-dimensional s.p.a.ce to contain low-dimensional s.p.a.ce. Because G.o.d was stingy, during the big bang He only provided the macroscopic world with three spatial dimensions, plus the dimension of time. But this doesn't mean that higher dimensions don't exist. Up to seven additional dimensions are locked within the micro scale, or, more precisely, within the quantum realm. And added to the four dimensions at the macro scale, fundamental particles exist within an eleven-dimensional s.p.a.ce-time."

"So what?"

"I just want to point out this fact: In the universe, an important mark of a civilization's technological advancement is its ability to control and make use of micro dimensions. Making use of fundamental particles without taking advantage of the micro dimensions is something that our naked, hairy ancestors already began back when they lit bonfires within caves. Controlling chemical reactions is just manipulating micro particles without regard to the micro dimensions. Of course, this control also progressed from crude to advanced: from bonfires to steam engines, and then generators. Now, the ability for humans to manipulate micro particles at the macro level has reached a peak: We have computers and nanomaterials. But all of that is accomplished without unlocking the many micro dimensions. From the perspective of a more advanced civilization in the universe, bonfires and computers and nanomaterials are not fundamentally different. They all belong to the same level. That's also why they still think of humans as mere bugs. Unfortunately, I think they're right."

"Can you be more specific? What does all this have to do with those two protons? Ultimately, what can the two protons that have reached the Earth do? Like the interrogator said, a single cilium on a bacterium can contain several billion protons. Even if these two protons turned entirely into energy on the tip of my finger, at most it would feel like a pinp.r.i.c.k."

"You wouldn't feel anything. Even if they turned into energy on a bacterium, the bacterium probably wouldn't feel anything."

"Then what were you trying to say?"

"Nothing. I don't know anything. What can a bug know?"

"But you're a physicist among bugs. You know more than I do. At least you aren't completely at a loss when faced with the knowledge of these protons. I beg you. Tell me. Otherwise I won't be able to sleep tonight."

"If I tell you more, you really won't be able to sleep. Forget it. What's the point of worrying? We should learn to be as philosophical as Wei Cheng and Shi Qiang. Just do the best within your responsibility. Let's go drinking and then go back to sleep like good bugs."

31.

Operation Guzheng "Don't worry," Shi Qiang said to w.a.n.g, as he sat down next to him at the meeting table. "I'm not radioactive anymore. The last couple of days they've washed me inside and outside like a flour sack. They didn't originally think you needed to attend this meeting, but I insisted. Heh. I bet the two of us are going to be important this time."

As Da Shi spoke, he picked a cigar b.u.t.t out of the ashtray, lit it, and took a long drag. He nodded, and, in a slow, relaxed manner, blew the smoke into the faces of the attendees sitting on the other side of the table. One of the people sitting opposite him was the original owner of the cigar, Colonel Stanton of the U.S. Marine Corps. He gave Da Shi a contemptuous look.

Many more foreign military officers were at this meeting than the last. They were all in uniform. For the first time in human history, the armed forces of the world's nations faced the same enemy.

General Chang said, "Comrades, everyone at this meeting now has the same basic understanding of the situation. Or, as Da Shi here would put it, we have information parity. The war between alien invaders and humanity has begun. Our descendants won't face the Trisolarans for another four and a half centuries. For now, our opponents are still human. Yet, in essence, these traitors to the human race can also be seen as enemies from outside human civilization. We have never faced an enemy like this. The next war objective is very clear: We must capture the intercepted Trisolaran messages stored on Judgment Day. These messages may have great significance for our survival.

"We haven't yet done anything to draw the suspicion of Judgment Day. The ship still sails the Atlantic freely. It has already submitted plans to the Panama Ca.n.a.l Authority to pa.s.s through the ca.n.a.l in four days. This is a great opportunity for us. As the situation develops, such an opportunity may never arise again. Right now, all the Battle Command Centers around the globe are drafting up operation plans, and Central will select one within ten hours and begin implementation. The purpose of this meeting is to discuss possible plans of operation, and then report one to three of our best suggestions to Central. Time is of the essence, and we must work efficiently.

"Note that any plan must guarantee one thing: the secure capture of the Trisolaran messages. Judgment Day was rebuilt from an old tanker, and both the superstructure and the interior have been extensively renovated with complex structures to contain many new rooms and pa.s.sageways. Supposedly even the crew relies on a map when entering unfamiliar areas. We, of course, know even less about the ship's layout. Right now, we cannot even be certain of the location of the computing center on Judgment Day, and we don't know whether the intercepted Trisolaran messages are stored in servers located in the computing center, or how many copies they have. The only way to achieve our objective is to completely capture and control Judgment Day.

"The most difficult part is preventing the enemy from erasing Trisolaran data during our attack. Destroying the data would be very easy. The enemy would not use conventional methods to erase the data during an attack, because it's easy to recover the data using known technology. But if they just emptied a cartridge clip at the server hard drive or other storage media, it would all be over, and doing so would take no more than ten seconds. So we must disable all enemies near the storage equipment within ten seconds of their detecting an attack. Since we don't know the exact location of the data storage or the number of copies, we must eliminate all enemies on Judgment Day within a very brief period of time, before the target has been alerted. At the same time, we can't heavily damage the facilities within, especially computer equipment. Thus, this is a very difficult task. Some think it's impossible."

A j.a.panese Self-Defense Forces officer said, "We believe that the only chance for success is to rely on spies on Judgment Day. If they're familiar with where the Trisolaran information is stored, they can control the area or move the storage equipment elsewhere right before our operation."

Someone asked, "Reconnaissance and monitoring of Judgment Day have always been the responsibility of NATO military intelligence and the CIA. Do we have such spies?"

"No," the NATO liaison said.

"Then we have nothing more to discuss except bulls.h.i.t," said Da Shi. He was met with annoyed looks.

Colonel Stanton said, "Since the objective is eliminating all personnel within an enclosed structure without harming other equipment within, our first thought was to use a ball lightning weapon."

Ding Yi shook his head. "The existence of this kind of weapon is now public knowledge. We don't know if the ship has been equipped with magnetic walls to shield against ball lightning. Even if it hasn't, a ball lightning weapon can indeed kill all personnel within the ship, but it cannot do so simultaneously. Also, after the ball lightning enters the ship, it may hover in the air for some time before releasing its energy. This wait time can last from a dozen seconds to a minute or longer. They will have enough time to realize they've been attacked and destroy the data."

Colonel Stanton asked, "What about a neutron bomb?"

"Colonel, you should know that's not going to work." The speaker was a Russian officer. "The radiation from a neutron bomb cannot kill right away. After a neutron bomb attack, the amount of time left to the enemy would be more than enough for them to have a meeting just like this one."

"Another thought was to use nerve gas," a NATO officer said. "But releasing it and having it spread throughout the ship would take time, so it still doesn't achieve General Chang's requirements."

"Then the only choices left are concussion bombs and infrasonic waves," Colonel Stanton said. Others waited for him to finish his thought, but he said nothing more.

Da Shi said, "I use concussion bombs in police work, but they're toys. They're indeed capable of stunning people inside a building into unconsciousness, but they're only good for a room or two. Do you have any concussion bombs big enough to stun a whole oil tanker full of people?"

Stanton shook his head. "No. Even if we did, such a large explosive device would certainly damage equipment inside the ship."

"So what about infrasonic weapons?" someone asked.

"They're still experimental and cannot be used in live combat. Also, the ship is very large. At the power level available to current experimental prototypes, the most that a full a.s.sault on Judgment Day could do is to make the people inside feel dizzy and nauseous."

"Ha!" Da Shi extinguished the cigar b.u.t.t, now as tiny as a peanut. "I told you all we have left to discuss is bulls.h.i.t. We've been at it for a while now. Let's remember what the general said: 'Time is of the essence!'" He gave a sly grin to the translator, a female first lieutenant who looked unhappy with his language. "Not easy to translate, eh, comrade? Just get the approximate meaning across."

But Stanton seemed to understand what he was saying. He pointed at Shi Qiang with a fresh cigar that he had just taken out. "Who does this policeman think he is, that he can talk to us this way?"

"Who do you think you are?" Da Shi asked.

"Colonel Stanton is an expert in special ops," a NATO officer said. "He has been a part of every major military operation since the Vietnam War."

"Then let me tell you who I am. More than thirty years ago, my reconnaissance squad managed to sneak dozens of kilometers behind Vietnamese lines and capture a hydroelectric station under heavy guard. We prevented the Vietnamese plan to demolish the dam with explosives, which would have flooded the attack route for our army. That's who I am. I defeated an enemy who once defeated you."

"That's enough!" General Chang slammed the table. "Don't bring up irrelevant matters. If you have a plan, say what it is."

"I don't think we need to waste time on this policeman," Colonel Stanton said contemptuously, as he lit his cigar.

Without waiting for a translation, Da Shi jumped up. "'Pao-Li-Si'-I heard that word twice. What? You look down on the police? If you're talking about dropping some bombs and turning that ship into smithereens, yeah, you military are the experts. But if you're talking about retrieving something out of it without damage, I don't care how many stars are on your shoulder, you aren't even as good as a thief. For this kind of thing, you have to think outside the box. OUT. OF. THE. BOX! You will never be as good at it as criminals, masters of out-of-the-box thinking.

"You know how good they are? I once handled a robbery where the criminals managed to steal one car out of a moving train. They reconnected the cars before and after the one they were interested in so that the train got all the way to its destination without anyone noticing. The only tools they used were a length of wire cable and a few steel hooks. Those are the real special ops experts. And someone like me, a criminal cop who has been playing cat and mouse with them for more than a decade, has received the best education and training from them."

"Tell us your plan, then," General Chang said. "Otherwise, shut up!"

"There are so many important people here that I didn't think it was my place to speak. And I was afraid that you, General, would say I was being rude again."

"You're already the definition of rudeness. Enough! Tell me what your out-of-the-box plan is."

Da Shi picked up a pen and drew two parallel curves on the table. "That's the ca.n.a.l." He put the ashtray between the two lines. "This is Judgment Day." Then he reached across the table and pulled Colonel Stanton's just-lit cigar out of his mouth.

"I can no longer tolerate this idiot!" the colonel shouted, standing up.

"Da Shi, get out of here!" General Chang said.
