Qinglan Consulting, project code C, fourth meeting.

At the beginning of the meeting, Rao Xin looked left and right, unlike the dozen or so people who came last time, the number of people attending the meeting this time was very small, himself, Professor Shen of Qinglan Consulting, an engineer who was said to be from the United States, and a nuclear physics expert who was in the same discussion group last time, the expert's surname was Tian, Rao Xin had only heard Professor Shen call him Lao Tian - they should know each other.

In front of these bigwigs, a video is being played for the thirty-third time.

Professor Shen and Professor Tian were talking to each other in a whisper, and the American stared, shaking his head and counting things on the paper with his head down.

It can be seen that they have seen a lot of things in the previous thirty-two times, and they are still learning more.

Especially the American, when he first played it a few times, he couldn't wait to look for information in it frame by frame, and find anything that could be questioned to question Shen Changwen.

Only Rao Xin himself, from the first time to the present, he almost didn't feel that there was any difference in what he saw, and he didn't think of anything more because of this, in his opinion, the content in this short video of more than ten seconds is very simple, so simple that one sentence can summarize all the information.

In a gravity-free environment, a man used a laser, and in two seconds, cut off two hundred and forty swords, killing two hundred and forty-one people.

The information is simple, not simple, it is a specific elaboration of the information.

Although the whole video is short, it is very informative, the angle of view is rotated, magnified, and the clarity of each lens is particularly high - in just a dozen seconds of picture, there are several G's in the converted data, of which each picture can withstand dozens of times of magnification to ensure that the details are still clear - only this is far beyond the needs of ordinary movie pictures, and it is also beyond the conceptual scope of conventional special effects production - it does not look like an ordinary big production.

The screen frequency of the video itself is also far higher than the production needs of ordinary movies, reaching more than 300 frames per second, which is five times that of ordinary movies. Of course, it's nothing compared to the content of the picture itself.

The work they have to do has nothing to do with how these images are realized, they need to analyze, assuming that the content of the pictures is real, how to evaluate the power of the weapons in them, and the possible means of countermeasures.

First of all, the most important detail, which the American has emphasized many times before, is the energy level assessment of this laser - which is also the main thing they analyzed in this meeting. Calculated from the time in the picture, this laser lasted a total of 2.534 seconds from the appearance to the end, during which time, the laser always maintained such an obvious operation process: lock on to the target, move to track, destroy the target, and lock on to the next target...... The number of all targets is 481, which means that the average time to lock on and destroy a target is only 5 milliseconds - for example, the speed at which a bee swings its wings is 5 milliseconds, that is, the laser successfully destroys the target in the time it takes for the bee to wave its wings once.

The video is recorded at a frequency of 300 frames, which is an average of 3 milliseconds per frame - in the time of two frames, the laser is exactly the right to complete the task of locking and destroying. Zooming in on the video footage, you can clearly see that the destroyed flying swords and human bodies have obvious physical processes that are vaporized by high temperatures, and the other three people have simply calculated on paper the minimum energy level to achieve this effect - the conclusion is obvious, the temperature of the laser itself is at least at the level of hundreds of thousands of degrees, or even millions of degrees - which even exceeds the temperature inside many stars.

This alone shows that if the civilization with this weapon really exists, then they will be far beyond the earth in terms of technology...... I don't know how many levels.

There is only one place on Earth where one can create such a high-temperature environment by equipment, and that is in the ITER (International Thermonuclear Test Reactor), which is still in the experimental stage. However, in ITAR, such a laser can only be maintained for a short time after hundreds of laser generating devices are focused together, and finally after the nuclear fusion is generated, and the plasma flow needs to be constrained by a strong magnetic field, but in the picture, it is a completely outdoor natural environment, and the generator is just a stick, from occurrence to contact, the duration is very short, just like turning on a flashlight - this is enough to show that the reliability of this device itself is very strong.

"And the controls, which are more incredible than the energy levels."

"Have you noticed the angle of the device itself moving - notice the ...... of the manipulator's hand muscles in the video?"

"You can try holding something in your hand, and when you're about to adjust the angle of the thing in your hand, there's going to be a slight muscle twitch, but there's no such movement in the picture, but the angle of the control itself is changing slightly."

"That is, the whole process from locking to destroying is fully automatic - I also don't believe that a human reaction speed can reach the millisecond level, and so many operations can be done in a short period of time - which is completely beyond the speed of nerve transmission." This sentence was what Professor Shen was saying, and he first spoke to Professor Tian and Rao Xin in Mandarin, and then to the American in English.

The American fell into thought and began to calculate on paper again, and after a moment, he stopped his movements and nodded at Shen Changwen.

Professor Tian added: "As you can see from the picture, the angle of the whole fine-tuning is very different. Let's look at the first destruction, two hundred and twenty swords are distributed almost all angles in the entire field of view, very uniform, an average of one coordinate point per square kilometer, an average angle between two coordinate points is about 20 degrees, pay attention to its movement trajectory, I used tracking software to automatically draw a trajectory map, you take a look. ”

Professor Tian opened the video again from the computer and changed to the clip he said, and then Rao Xin was surprised to see that all the trajectory routes scanned by the red laser were recorded - in the process of those flying swords flying at high speed, the red laser was like threading a needle, from the first target, to the second, to the third......

The whole process perfectly follows the scanning method of spherical projection - the trajectory of the laser is a very beautiful spiral curve, starting from the pole where it just started, and gradually expanding the running radius in order from near to far, like an invisible hand, delicately controlling the light to stir in space. This process does not move at a uniform speed, but is accompanied by a process of acceleration, stopping, acceleration, and stopping again - every brief moment of stopping is a process in which the laser focuses on the target and releases energy.

Rao Xin also found a noteworthy detail in this process - when the laser leaves a target, there is no way to distinguish whether the target has been destroyed or not from the picture alone, and those swords even maintain the overall shape and stable flight state to continue flying, but the laser automatically leaves.

It wasn't until near the end of the entire destruction process that the sword body of the first destroyed target began to break and separate.

"This means that the laser already has very mature parameters for destroying these targets, and at the same time the energy is saturated and overloaded - so that the destruction is ensured. Leaving without destroying is extremely wasteful in terms of efficiency. ”

In layman's terms, the laser destroying a flying sword is compared to a person knocking down a person with one punch, which doesn't sound difficult to do, but to knock down two hundred and forty people in a row in a very short period of time means that the boxer must have a very accurate estimate of the strength of his shot, as well as the opponent's ability to resist blows, in order to ensure that each blow does not waste too much force, and to ensure that each punch can be truly knocked down.

"In the design of weapons, we usually have to leave a margin of 100 percent, or even more than 200 percent, in the lethality of weapons, and in specific combat behavior, it is not too much to project the necessary firepower hundreds, thousands, or even tens of thousands of times. In the Iraq war, an average of 250,000 rounds of ammunition killed one person...... But this, this...... This machine is as precise as the devil's scalpel," this is the American evaluation, "and in front of it,* it is like a firecracker, like a child's mischievous toy." ”

Rao Xin couldn't agree with the Americans' assessment anymore.

Rao Xin couldn't help but scratch his head - it's right to be serious, but ...... Whether it's a movie or a game, is it necessary to take the details seriously to this extent?

As a science fiction author, he is naturally able to realize what this kind of weapon, which is completely beyond imagination, super lethal efficiency, and super accuracy, means. Imagine what it would mean if such a person in the video appeared on Earth with such a weapon? In two seconds, he was able to clear all targets within a 200-square-kilometer radius — and with precision, a slaughter that was more terrifying than a nuclear bomb. In front of the automatic sighting system that ensures lock-on destruction in 5 milliseconds, all the planes on the planet* have become ornaments, which is simply the perfect form of the US TMD (Theater of Operations* Defense Program). Even the flying sword, which is only a little more than a meter long and more than a dozen centimeters wide, can be accurately locked, not to mention these huge *s on the earth.

After this analysis, several people in the scene looked at each other—after an awkward silence, everyone burst out laughing—and on an illusory topic, they actually discussed a certain sense of reality, as if real aliens were going to appear on Earth and invade.

"The only possibility for this weapon is that it runs out of energy and takes a break for a while," the American said, "and the instantaneous power at the time of his firing is almost equivalent to the ignition power of the ITER, and perhaps the firing gap is his weak point." ”

"This technical premise does not exist, and in the hypothetical technical background, the functional system of this weapon is an antimatter battery," Mr. Shen said, "and the energy it stores is equivalent to the annual electricity consumption of a small country." Not to mention two seconds, even if it is two hours, it will not let it run out of energy. ”

Antimatter batteries? How high is the budget for this project?

Funds are burning!

"Yes, antimatter batteries. Now let's talk about the weapons we have, these are not all from the earth," Shen Changwen opened another video and said, "First of all, let's take a look at this shield-like armor, let me remind you first, it is an electromagnet. ”
