In a small conference room in the satellite launch center, more than a dozen people including Su Zhe, Bao Zhengyi, and Ning Changsheng looked at the big screen in the conference room.

These people are the core personnel of the Xuanwu Plan, either technical consultants, or the executors of the Xuanwu Plan.

While watching the deployment of the Xuanwu Plan on the big screen, everyone listened to the explanation of Zhang Gaoming, director of the Lingzhou Optoelectronics Research Institute.

"After more than three months of assault, the foundation construction of the three thousand SS-defense system subsystems deployed on the ground of the Xuanwu plan has been completed, and so far, the construction of five hundred subsystems has been completed."

"The four-dimensional optical positioning technology system in the completed subsystem has been put into use...... Let's put it this way! The 4D optical positioning technology system is very, very good, and it fully meets the design expectations......"

"Let's take a closer look at the big screen, and the next pictures are the practical application of the four-dimensional optical positioning technology system."

A small four-winged drone flying appears in the main screen of the large screen, and the camera mounted under the drone can be clearly seen.

On both sides of the main screen are displayed various parameters of the small quadcopter, such as the structure of the small quadcopter, the spatial position information of the drone, the flight trajectory of the drone, and so on

Judging from these data, this is a small civilian UAV, flying at an altitude of 300 meters and latitude and longitude......

Its flight speed is eight meters per second.

Then, the main screen changes from a drone to a passenger plane, and the icon on the passenger plane can be clearly seen through the screen.

The parameters on both sides of the main screen show that the airliner is flying at an altitude of 11,000 kilometers and a speed of 1,000 kilometers per hour......

After everyone learned about the passenger plane, a satellite appeared in the main screen, a satellite that everyone is familiar with.

The satellite is spherical and has several needle-like antennas, codenamed DFH-1.

From the parameters on both sides of the main screen, it is known that the satellite is flying in an orbit of 1,500 kilometers above the ground, and its speed is 7.3 kilometers per second.

Zhang Gaoming looked at everyone with a smile and said: "Everyone has seen that the detection ability of the SS-defense system is still very strong, for now, ultra-low altitude or finding a cover, or more than 10,000 kilometers from the ground, only in this way can you escape the detection of the SS-defense system." ”

Instantly, there was applause in the conference room.

After a while, seeing that the applause stopped, Zhang Gaoming continued: "But this is now, when we deploy a probe in space, it will be really difficult to hide." ”

The crowd applauded again.

At this time, the main screen switches again.

Although the main screen is not clear enough, everyone can still distinguish it.

The main screen shows a space solar power station in the synchronous orbit of outer space led by Academician Zhao Guoan of Northwest University of Electronic Science and Technology.

In the picture, the overall outline of the space solar power plant is clearly visible, but many details are not clear.

It's not as clear as the previous three sets of images.

However, the parameters of the space solar power plant are still displayed on both sides of the main screen.

Its spatial position, velocity, altitude, orbit, and so on

"As you know, the altitude of the effective detection of the ground part of the SS-defense system is 10,000 kilometers, and this effective detection refers to the ability to detect almost all parameters of the target......" Zhang Gaoming explained.

Everyone knows the parameters of the SS-defense system subsystem deployed on the ground, and also knows the meaning of effective detection.

For example, the space solar power station of the Chase Light Project is in a synchronous orbit of more than 30,000 kilometers, and compared with the effective detection distance of the ground part of the SS-defense system, it can only do what is shown on the big screen.

"The purpose of launching 36 probes tomorrow is to broaden the detection range of the SS-defense system, and when these 36 probes are deployed in space, the detection range of the SS-defense system will be broadened to 300,000 kilometers." Zhang Gaoming said with a smile on his face.

Seeing Zhang Gaoming laughing, everyone in the conference room also laughed.

The crowd began to speak.

Some people say that these thirty-six probes were built too hastily, that the life span of half a year is too short, that some people say that they were prepared for two small rows that are about to collide, and so on

Not a single person said that the SS-defense system was not strong enough.

"That's right! I'm here to say that tomorrow we will watch the whole process of 36 stars through the SS-defense system, and I believe it will give you a different experience. Zhang Gaoming reminded with a smile.

The crowd applauded in anticipation.

"Good! Now that we have an intuitive understanding of the detection capability of the SS-defense system, let's take a look at the interception capability of the SS-defense system. Zhang Gaoming said with some excitement.

The crowd became excited, some said to see the death light destroy the satellite, and others said to see the death light bombard the asteroid.

Zhang Gaoming smiled helplessly and said, "Don't joke with me, everyone knows the whole process of the Xuanwu Project, and it can be done to test the detection ability of the SS-defense system, while the test of the dead light is carried out secretly." ”

Hearing Zhang Gaoming say this, many people in the conference room smiled embarrassedly.

"Next, I'll show you the video of the four levels of death light test, and the first video shows the test video of the first level of death light......" Zhang Gaoming explained.

The video starts playing in the main screen.

It is easy to tell from the environment of the video that the place where the test was tested was underground.

In the gray picture, it is easy to see a thick tube, and it is possible to see the rocky target area dozens of meters away.

Everyone knows that this thick tube is the barrel of a dead firing cannon.

Suddenly, the tip of the Death Light Transmitter lit up with a surging red light, followed by a flash of red light.

Immediately, a groove appeared on the rocky target area a few dozen meters away.

After waiting for a while, the tip of the Death Light Transmitter lit up again, and then an extremely imperceptible red light flashed, and a tiny hole appeared in the groove of the rocky target area.

When the main screen is playing, the various parameters of the first-level death light test are displayed on both sides.

Everyone watched the video while listening to Zhang Gaoming's explanation.

"You can guess from watching the video that the test site is 200 meters underground, and I won't say the specific location."

"The test in the video is a first-class dead light, with a barrel of one meter in length and thirteen centimeters in diameter."

“……”

"Good! The first test was completed, and the beam was ten centimeters in diameter, the beam lasted 0.01 seconds, and the depth of the rock depression was one centimeter. ”

"The second test was also completed, with a beam diameter of one millimeter, a beam duration of 0.01 seconds, and a depth of ten meters in the rock depression."

"What I want to explain is that the diameter of the beam of the first-stage dead light is selectable, and the size and length of its output power are also optional."

"Of course, the upper limit of the output power of different levels of death light is different."

“……”

On the big screen, after the first-level deadlight test video is played, the second-level deadlight test video will be played, followed by the third-level deadlight and the super-deadlight.

The barrel length of the second grade is three meters and the diameter is 55 centimeters, the barrel of the third level is seven meters long and the diameter is 110 centimeters, and the barrel of the special death light is 90 meters long and 33 meters in diameter.

Relatively speaking, in the Xuanwu plan, the super-grade death light is deployed the least, there is no way, its volume and power are there, and it is already very good to be able to deploy three groups.

According to Zhang Gaoming, these three groups of super-grade deathlights are prepared to deal with huge asteroids, and as for those flying machines, the first, second, and third-level deathlights are completely sufficient.

In terms of the number of deployments, the first tier is the largest.

The larger the caliber, the greater the power, the less flexible, the smaller the number of its deployment.

After watching the test video of the four levels of death, everyone in the conference room was extremely excited.

Everyone knows that when the Xuanwu plan is completed, there is no need to worry about any threats, and they will be able to develop step by step.

"Good! After watching the video of the test, everyone must have confidence in the Xuanwu plan, and have a preliminary understanding of the detection and interception capabilities of the SS-defense system. Zhang Gaoming was very excited.

As the leader of the Xuanwu Plan, Lingzhou Optoelectronics Research Institute is very aware of how much manpower and material resources have been invested in the past few months to achieve the current results.

At the same time, he also felt the efficiency and wonder that comes from whatever it takes.

At this moment, he still couldn't forget the huge barrel of the Super Death Light.

Ninety meters long, thirty-three meters long, the big guy looks like an extended version of a gasoline drum from a distance.

The strength of the super-grade dead light is strong, but the flexibility is incomparable compared to the first, second and third level dead light.

At the same time, that amazing power, full power transmission, lasts for one minute, and consumes the same amount of electricity as a city with a million people in a day.

On the other hand, he prefers one, two, and three levels of death.

Of course, he didn't want to use the Super Death Light in reality, because he knew that once he used the Super Death Light, it would mean that humanity would encounter a devastating disaster.

Just as he was thinking, everyone in the conference room began to discuss.

These people talked about wanting to see the true strength of the SS-Defense system, and wanted to see the combined effect of the SS-Defense system's detection and interception.

Although everyone had just seen the detection effect of the SS-Defense System and the test effect of the four levels of Death Light, they did not see the effect of combining the two.

The more people discussed, the more they felt uncomfortable.

Zhang Gaoming looked at everyone and reminded: "Don't think about the test of combining the two, let's put it this way!" There's no need, we won't use the Death Light to intercept it, don't say you don't know why! ”

Everyone thought about it and became discouraged.

They knew that a combination of the two tests was unlikely, after all, there were too many factors to consider.

Su Zhe listened to everyone's discussions, and his heart was also itchy.

To be honest, he had a clear understanding of the Xuanwu program, and he had a good understanding of the detection and interception capabilities of the SS-Defense system.

But when he watched the previous video, he was still very excited and excited.

Although he knew that he could imagine the image of the SS-Defense system intercepting in his mind, no matter how he imagined it, it was not real, and it was not as good as what happened in reality.

Take Super Dying, for example.

He participated in the design of the super death light throughout the whole process, and he knew all the parameters of the super death light, but when watching the video, he was still shocked by the volume of the super death light.

He believed that when he saw the super-grade death light object tomorrow, he would be even more shocked.

So, he also wanted to see the effect of the combination of detection and interception of the SS-defense system.

Unconsciously, a scene came to mind in his mind.

A huge asteroid flew towards the Earth at a rapid pace, and three sets of super-grade dead lights fired red beams at the same time......

Just thinking about it, Bao Zhengyi, who was sitting next to him, said: "Su Zhe! Do you think those two asteroids that are already destined to collide will bring disaster to us humans? ”

Su Zhe saw that everyone in the conference room was looking at him, and he was a little confused.

After listening to the reminders of Professor Ning Changsheng and Bao Zhengyi, he realized that while he was thinking to himself, everyone in the conference room talked about two asteroids that were about to collide.

Everyone had their own opinions.

Some people think that the collision of these two asteroids will not affect humans on Earth.

Some say that there is a hope that there will be a wreckage that threatens humanity to fly to Earth, so that there is a place for the SS-defense system.

As he spoke, everyone looked at Su Zhe and wanted Su Zhe to talk about it.

Zhang Gaoming saw that Su Zhe was a little confused, and said: "Now the relevant institutions at home and abroad agree that the two asteroids will collide, and the result of the analysis of the relevant domestic institutions is that after the two asteroids collide, the possibility of the wreckage flying to the earth is ......."

Regarding the collision of two asteroids at a distance of 3 million kilometers from the earth, relevant institutions at home and abroad have reached a consensus that the two asteroids will collide.

However, domestic and foreign perceptions of the consequences of the collision of two asteroids are completely different.

The relevant domestic agencies are cautious, believing that it is impossible to determine whether the wreckage after the collision will bring disaster to mankind before the two asteroids collide.

We can't be blindly optimistic, and we must prepare for the worst.

Foreign agencies are very optimistic, according to their semi-public information, they have done a simulation of the collision process of two asteroids, believing that the possibility of the collision debris to mankind is very small.

However, the relevant foreign institutions are still very pragmatic and still prepare for the worst.

From the discovery of two asteroids to the present, relevant foreign agencies have intervened four times, but unfortunately all four times have failed.

He disagrees with the simulation results of the collision process of two asteroids made by relevant foreign institutions.

Even if we know the orbital parameters, shape, mass, mass distribution, etc., it is difficult to know the internal structure of the two asteroids.

So, how to believe the simulation results of the collision process of two asteroids.

According to the simulations of relevant domestic institutions, even if the debris of the collision of these two asteroids has little impact on the earth, it is very likely that these debris will hit other asteroids, causing the orbit of these asteroids to change.

It's a ripple effect, and no one can guarantee that these re-orbited asteroids won't hit Earth.

After Zhang Gaoming finished introducing, he looked at Su Zhe with a smile.

Everyone in the conference room also looked at Su Zhe with a smile, and they wanted to know the answer from Su Zhe's mouth.

Or rather, they wanted Su Zhe to affirm their statement.
