After looking at the current political pattern of mankind, Pang Xuelin began to look at the development history of Fleet International in the past hundred years.

To Pang Xuelin's surprise, the people who witnessed him using the law of the dark forest to deter the three-body civilization in the "Gravity" communication module were still alive.

After serving as the supreme leader of Fleet International for twenty years, Vader chose to hibernate, and he has since woken up several times, but the awakening time has not been long, and after making sure that the overall development of Fleet International has not deviated from the track, he is still in a state of hibernation.

Luo Ji was the second leader of Fleet International, a position he held for more than twenty years and chose to hibernate at the age of sixty.

Ding Yi also stayed at the head of the Supreme Science Council for 20 years, and then woke up and slept to ensure that the overall level of human science and technology development was not out of shape.

Hines chose to wake up after Ding Yi and took over as the leader of the Supreme Scientific Council, which is also in hibernation.

The third leader of Fleet International was Rediaz the Wall-Facer, who was replaced by Taylor after Rediaz left office.

The first commander of the Solar System Fleet was Zhang Beihai, who awakened in the year 108 of the Crisis Era.

Zhang Beihai stayed in this position for ten years, and then Chu Yan stepped forward to take over.

……

It is these old fellows who have gone forward and succeeded each other to ensure that the development of Fleet International as a whole is on the right track.

However, in recent years, there has been a certain crisis within the fleet internationally.

The existence of these people in Vidro was ridiculed as gerontocracy by the Earth International, and these people have held high positions for a long time, which has also caused dissatisfaction among the young Zhuang faction in the Fleet International.

Later, perhaps Luo Ji and Vader realized that this was not the way to go, and began to hibernate one after another, gradually releasing power.

In the last fifty years, the leaders of Fleet International have basically disappeared from the human body.

Vader's influence in the fleet international has also been deliberately minimized.

Even this time, the reason why Fleet International woke up Pang Xuelin was because of the arrival of the Three-Body Civilization Probe, and the high-level Fleet International was divided into two factions on how to deal with the Three-Body Civilization.

Originally, in this case, it was completely possible to consider reviving Vader and Zhang Beihai and listening to the opinions of these people.

However, considering Vader's influence within Fleet International, the top management of Fleet International decided to choose to revive Pang Xuelin, and Pang Xuelin made the decision.

After all, although Pang Xuelin is the founder of Fleet International, he has not held a high position for a long time.

Moreover, nominally, Pang Xuelin is also the supreme commander of the fleet international, and has the right of veto on major decision-making issues involving the future of mankind.

Such a character is the most suitable for the current political environment.

……

After reading the history of the development of Fleet International, Pang Xuelin turned his attention to the fields of basic science and military affairs.

In the field of basic science, mankind has also made a lot of breakthroughs in recent years, and although the construction of the theory of great unification has not yet been completed, considerable progress has been made in experiments.

Twenty years ago, mankind's most powerful hadron accelerator was the Ringwood Orbital Accelerator, which discovered the existence of gravitons, further complementing the foundation of the grand unification theory.

The next-generation orbital accelerator has also entered the construction stage.

Many scientists have predicted that as long as the orbital accelerator around the sun is completed and the theory of great unification is verified, mankind's basic science will surely make a leap forward by leaps and bounds.

Even the legendary light-speed spaceship is likely to become a reality.

At present, the most powerful interstellar warship of mankind is the use of non-working mass nuclear fusion propulsion technology, and the fastest speed can reach 20% of the speed of light, which is already twice the speed of the fleet sent by the three-body civilization back then.

And the weapons carried on these interstellar warships, in addition to conventional weapons such as electromagnetic railguns, laser cannons, particle beam cannons, and interstellar missiles, also have a killer weapon, known as gravity bombs.

This is a super weapon developed by scientists after the discovery of graviton, this kind of bomb, can create a powerful gravitational field near the spacecraft in a very short time.

Once the ship is trapped in this gravitational field, the ship's body will break down, and at worst, the entire ship will be torn apart by gravity.

In addition, humanity has an even more powerful weapon - the antimatter bomb.

The antimatter bomb is arguably the most powerful weapon in human history, and the annihilation of positive and antimatter turns into pure energy.

According to Einstein's special theory of relativity's mass-energy equation, one gram of antimatter contains energy equivalent to three atomic bombs dropped on Hiroshima, Japan, and the largest antimatter bomb made by humans weighs one ton.

The power of an antimatter bomb is equivalent to a thousand stellar hydrogen bombs (100 million tons of yield).

It is said that this bomb was developed by humans when Ray Diaz was in power, and mankind invested huge resources.

In addition, the antimatter thruster developed based on antimatter technology has also entered the research and development stage.

In the laboratory, considerable progress has been made in the technology of annihilation of positive and antimatter to obtain energy, and according to scientists' estimates, within 50 years, mankind will be able to complete the construction of antimatter-powered spacecraft.

At present, the Solar System Fleet under the jurisdiction of Fleet International has more than 3,000 stellar-class warships, and tens of thousands of antimatter bombs and gravity bombs are in reserve.

Such a powerful strategic force has given mankind the courage to deal with the three-body civilization fleet.

However, when he saw the human material technology, Pang Xuelin frowned slightly.

In the field of materials science, he does not see the shadow of strongly interacting materials.

The so-called strong interaction materials have to talk about strong interaction forces.

In nature, the four basic interaction forces are strong interaction force, weak interaction force, electromagnetic force and gravitational force.

The so-called strong force is the force acting between the hadrons.

The first strongly studied interaction was the nuclear force between nucleons (protons or neutrons), which is the action that causes nucleons to combine into atomic nuclei.

Later, after scientists discovered the π mesons that interact with nucleons, experiments have successively discovered hundreds of particles with strong interactions, which are collectively called hadrons.

It binds quarks in protons and neutrons together, and protons and neutrons in atoms.

Strong force is the strongest of the four basic forces, but it acts on the second shortest range.

The range of action of the force is short, but it manifests itself in different forms.

At long distances, the strength is zero. When the distance between the nuclei is less than 2*10^-15m, the strong force takes effect, which is manifested as a huge repulsive force.

But when the two get closer, after reaching 0.8*10^-15m, the strength will be converted into attraction.

This attraction can bind the various structures inside the nucleus together.

Weak interaction force, abbreviated as weak force.

The weak force is the second weakest of the four fundamental forces (only stronger than gravity), and this force has a shorter range than the strong force, but much weaker than the strong force. The weak force can cause protons to decay into neutrons, creating the conditions for nuclear reactions in matter. Current physical theories have been able to prove that weak and electromagnetic forces can be converted into each other.

The electromagnetic force is the second strongest force in the universe, 100 times weaker than the strong force and 10 billion times stronger than the weak force.

The electromagnetic force is much farther away than the strong force, but it is not infinitely far either. Do only with atomic or molecular ranges.

Electromagnetic force is manifested as repulsion of the same sex and attraction of the opposite sex, and the electromagnetic force dominates all the chemical changes (including living organisms) and most of the physical properties (hardness of objects, etc.) of all things in the world, and it is also the most common force that we can come into contact with in our daily life.

Gravitational force is the weakest force, 10^36 times weaker than the electromagnetic force. But the gravitational force acts at an infinite distance.

Theoretically, only neutron star materials are strongly interacting materials.

However, in "Dark Forest", the three-body civilization can already extract the strong force from the nucleus, so that the strong force still works under the condition that the distance is several orders of magnitude higher.

In this way, the atoms of matter can be firmly locked by force, the surface temperature is close to absolute zero, there is basically no vibration, and the strength is thousands of times higher than that of the most powerful materials of mankind.

The three-body civilization detector "Water Drop", composed of this material, easily destroyed 2,000 stellar warships of mankind.

Pang Xuelin frowned.

Judging from the strong interaction materials, although mankind has made considerable progress in the field of basic science in the past two hundred years, and can even look at the three-body civilization, there is still a certain gap between the overall scientific and technological level and the three-body civilization.

Even with the current strength of the human solar system fleet, when encountering the three-body civilization water drop probe, the result may not be much better than in the original book.

And why did the Three-Body Civilization still send a probe when it had clearly informed the other party that it knew the laws of the Dark Forest, it was nothing more than the following purposes.

Since the entire solar system has been completely controlled by humans, it is difficult for Zhizi to sneak in, so entering through a probe is undoubtedly the best way to understand the current level of technological development of human civilization.

As long as it is determined that human beings still do not have the ability to communicate with gravitational waves, the Three-Body Civilization can carry out large-scale electromagnetic interference on the sun through water droplets, thus making human beings lose the ability to deter the dark forest through the sun.

Moreover, by taking advantage of the indefensible nature of water droplets, the three-body civilization can also completely destroy the space power of mankind, thus making mankind lose hope.

"Gravitational Wave Communication!"

Thinking of this, Pang Xuelin hurriedly called up the gravitational wave technology from the tablet, and after watching it for a long time, Pang Xuelin couldn't help but break out in a cold sweat!

The main reason why he did not establish the dark forest deterrence system back then was that the deterrence of amplifying electromagnetic waves through the sun was congenitally insufficient, and once it was interfered with on a large scale, it basically had no meaning.

Therefore, the gravitational wave dark forest deterrent system is the ultimate deterrent.

In the plan left by Pang Xuelin back then, gravitational wave communication was also a key project to break through.

Under normal circumstances, two hundred years is completely enough for Ding Yi and them to complete the research on gravitational wave communication.

But!

Due to the struggle between the old man faction and the young Zhuang faction within the fleet international, after the young Zhuang faction took the leadership of the fleet international fifty years ago, it cut a large number of projects from the old man faction era.

As a result, gravitational wave communication technology, which is about to succeed, has suffered an unjustified disaster.

In the past 50 years, mankind has only completed the principle research of gravitational wave communication technology, but has made a lot of investment in neutrino communication technology.

The problem is that the one-way nature of neutrino communication makes it possible for the three-body civilization to intercept neutrino information through the two-dimensional expansion of sapients.

And the principle of omnidirectional communication of gravitational wave technology is the best way to deter the dark forest!

If human beings do not have gravitational wave communication technology, even if Vader and they are still there, and they do not know the characteristics of water droplets, once they let water droplets enter the solar system and seal the sun, what awaits human beings will probably be a catastrophe.

After all, Tomoko can't physically affect humans, but water droplets can!

When the time comes, my last mission, in the battle of doom, to save as many solar system fleets as possible, I am afraid that there will be no way to complete it at all.

"!"

After reading these materials, even with Pang Xuelin's big heart, he couldn't help but sweat coldly.

These guys almost broke something big!

The only thing they do right is to wake themselves up six months before the droplets enter the solar system.

It's still too late.

……

Early the next morning, Cao Bin came over to pick up Pang Xuelin.

Cao Bin came with a senior international officer of the fleet.

"Hello Professor Pang, welcome to the new era, I am Prit Bell, senior commissioner of the International Standing Committee of the Fleet, welcome to the new era!"

"Hello!"

Pang Xuelin shook hands with Bell and smiled faintly.

Bell smiled: "Professor Pang, I think Mr. Cao Bin has already told you about the current form, there are still six months before the Trisolaran probe enters the solar system, and there is a lot of debate within the fleet international about how to deal with these probes. Some people tend to send all the solar system fleets to show the human military might to the Trisolarans, after all, we have now established the Zhizi blind zone within the orbit of Pluto, and the Trisolarans don't know what kind of powerful fleet we have built, so sending all the solar system fleets will help bring the Trisolarian civilization back to the negotiating table. ”

"Another part of the people expressed their opposition, they believe that the solar system fleet should be fully dispatched, and after capturing the Trisolaran Civilization Probe, it should directly kill the main fleet of the Trisoranium Civilization. Now the technical level of the human fleet is no less than that of the three-body civilization, and even several times more in number, we can completely crush the three-body fleet, and even launch a counterattack on the home planet of the three-body civilization! ”

"At present, it is mainly the two points of view that are arguing, and the reason why we have awakened you is partly because of our respect for you, and it is your efforts that have enabled human civilization to build a powerful solar system fleet, so we also hope that you can witness this glorious moment with your own eyes. On the other hand, in the Basic Law of Fleet International, you have a veto power over any major decision that concerns the future of humanity. As long as you make your choice, we will act on your decision. ”

Pang Xuelin looked at Pratt Baker lightly and said, "Isn't it necessary to wait for the International Plenary Meeting of the Fleet to make a decision on this decision in two months?" I would like to understand the current situation before making a decision. Also, during this time, I am going to go back to Earth. ”

The whistling cold wind carried fine raindrops, blowing Yan Xiangdong unable to open his eyes, and the weightlessness of the violent fall made him feel dizzy.

Below, you can faintly feel the flashing police lights in the rain.

The ground was rapidly enlarged in Yan Xiangdong's eyes, is death finally coming?

Bang –

……

"Ah......h

Yan Xiangdong sat up from the bed suddenly, the green tendons on his face burst out, and he gasped for breath, as if a person who had been drowning for a long time suddenly surfaced.

"I ...... I'm not dead? ”

Yan Xiangdong subconsciously lowered his head to check his body, all four limbs were complete, and his body was intact.

How did you survive a fall from a 30-story building with no shelter below, and the odds of surviving are lower than winning the lottery?

Yan Xiangdong tried to calm his pounding heart and looked around.

The room is simply furnished, a solid wood desk occupies most of the space, and the party flag and national flag are placed on the desk, representing the authority of the captain of the criminal investigation brigade of the Jiangcheng Public Security Bureau.

Behind the desk is a cabinet of case files, and the small bed I am in is opposite the desk.

Yan Xiangdong is familiar with this place, this is his office.

For the 2.23 serial murder and corpse mutilation case, Yan Xiangdong has lived here for the last few nights.

"But how did I end up here? Even if I hadn't died, and I had fallen from a thirty-story building, my colleagues should have taken me to the hospital anyway? How could you let me lie in the office and ignore it? ”

The suffocating feeling brought by extreme fear made Yan Xiangdong's mental acuity drop to the freezing point, but even so, he still found something unusual.

For example, he was wearing the black jacket he had changed into last night.

Last night, the internal staff Xiao Xu bought a supper for the task force, and accidentally spilled a cup of milk tea on Yan Xiangdong's jacket.

At that time, Yan Xiangdong specially changed his clothes, but now, this black jacket was actually worn completely on his body, leaving no stains.

For example, when he climbed the unfinished building yesterday, his left arm was cut by a section of steel bars protruding from the corner of the stairs, but now, his left arm is intact.

Everything around him made Yan Xiangdong feel a strange sense of familiarity, but he couldn't say where this familiarity came from.

"What the hell is going on? Is it all just a dream? ”

Yan Xiangdong frowned, turned over and got out of bed.

As soon as I walked to the door, the office door was suddenly pushed open, and a handsome-looking young policewoman broke in with a cup of milk tea and a hamburger.

"Ah......h

The policewoman was startled by Yan Xiangdong, who suddenly appeared at the door, and the soles of her feet were mixed with garlic, and the whole person involuntarily fell forward.

"Be careful!"

Yan Xiangdong stepped forward quickly, subconsciously holding the policewoman's arm, but the milk tea in the policewoman's hand splashed on Yan Xiangdong's jacket.

"Oh, Team Yan, I'm sorry, I'm sorry, I've prepared a supper for everyone, thinking that you can eat some ...... too"

The policewoman was shocked, and hurriedly put down the cup and hamburger, and took out a tissue to wipe the stains on Yan Xiangdong's body.
