Within a few Planck time lengths, even a spacecraft that sails with curvature has only sailed a short distance, and its speed, direction of movement and other parameters have long been taken into account by Xiao Yu, and the launch direction has already been corrected in the launch module.

After the launch order was issued, the torrent of minus 100,000 tons of tachyons, which had been bound to the launch window and constantly moving in a circular motion, quickly rushed towards the target direction. They travel far faster than the speed of light, and even, until now, Xiao Yu has not specifically measured the speed of the tachyon.

The ultra-long-range communication is based on the phenomenon of quantum entanglement, the principle of quantum entanglement is based on a tachyon called A1 by Xiao Yu, the faster-than-light detection instrument is based on a tachyon called A3 by Xiao Yu, and the attack module of the negative matter cannon is based on a tachyon called G7 by Xiao Yu. These three types of tachyns are the most versatile. By now, Xiao Yu had discovered dozens of different types of tachyons, each of which had subtle differences in nature. For these dozens of tachyns, Xiao Yu can only roughly rank their speeds, and even the slowest Z2 tachyns cannot be specifically measured.

Among these types of tachyons, the fastest is undoubtedly the A1 type tachyon, which has caused the quantum entanglement principle and has been widely used in civilizations of level 3 and above.

But even with their speed, one thing is for sure: there is still a limit to their speed, not as fast as it is rumored. It is certain that even if it is a super-distance communication jishu, after the distance reaches the upper limit, such as one on one side of the Milky Way and one on the other side of the Milky Way, a distance of 100,000 light-years. They can also experience significant delays, and it is even possible that they will be decoherent and unable to communicate at all.

Xiao Yu guessed that it may be precisely because of this reason that the sixth-level civilization abandoned the ultra-long-distance communication technology commonly used by the fifth-level civilization, and instead adopted a more advanced technology, which should be the "space broadcasting" technology used by the white dwarf alien beast and the guardian civilization.

Xiao Yu had heard the rumors a long time ago. The sixth-level civilization has initially mastered space technology, so this kind of space broadcasting technology is worth considering.

Since the tachyon of the negative more than 100,000 tons were all bound to the negative matter cannon before, then they and the negative matter cannon can be regarded as a unified system. Now that they have been launched, it means that the mass of this negative material cannon has been reduced by minus 100,000 tons. In other words, it's its quality. At this moment an increase of more than a hundred thousand tons.

This phenomenon was already in Xiao Yu's inference. The phenomena it can cause were also accurately predicted by Xiao Yu.

At this moment, due to the change in mass, the orbit of the negative matter cannon, which weighs hundreds of millions of tons, changed a little, and its orbit was a little closer to the brown dwarf. If left unadjusted, this negative cannon will be there for a long time to come. Getting closer to the brown dwarf so much that Zuihou crashed into it.

When making tachyons, positive matter of the same mass is accompanied, and the positive matter is polymerized from quarks into baryons, and then from baryons to the most basic hydrogen atoms. Zuihou polymerizes into the simplest substance in the universe, hydrogen. To make this minus 100,000 tons of tachyon, Xiao Yu also harvested more than 100,000 tons of hydrogen as a by-product.

However, in order to make this minus 100,000 tons of tachyon, the energy invested by Xiao Yu is far more than this number if converted into mass.

At the moment when the fast torrent was launched, Xiao Yu saw a magical phenomenon.

The interior of the star system is a place with a relatively rich concentration of matter, and there is a large amount of cosmic dust in an invisible place. Xiao Yu had already determined the forward trajectory of the tachyon torrent, and after the tachyon torrent emptied all the material in their path, Xiao Yu's detection instrument immediately entered this orbit.

Here, after the rapid torrent has passed, it has become a vacuum of extremely high purity, and in this environment, many wonderful and incredible physical phenomena will occur. Xiao Yu guessed that perhaps it was the discovery of tachyon that led to intelligent beings being able to obtain a vacuum of extremely high purity, and only after emptiing the influence of matter on space to the greatest extent could they carry out research on space, and finally enter the stage of sixth-level civilization.

The target spacecraft was about 10 million kilometers away from the negative matter cannon. Above this distance, with the transmission speed of the tachyon, Xiao Yu could not detect the time delay. In other words, just a moment after the tachyon torrent was launched, they were on the target ship.

The county-level ship disappeared. It disappeared so abruptly, and at this moment, not only the faster-than-light detection module on the negative matter cannon, but also the ultra-long-range communication instruments in the Beijing could no longer find this county-level spacecraft.

In the ultra-distant communication instrument, the quantum, which was originally in an entangled state, underwent a decoherence phenomenon at the same time as the county-level spacecraft disappeared. In other words, it is impossible for Xiao Yu to contact the county-level spacecraft through over-distance communication.

It just disappeared, simple, clean, without any movement, without leaving a trace.

That's the power of the Negative Matter Cannon.

"Good, just as I expected." Xiao Yu thought with satisfaction, and quickly began to evaluate the current operation of the negative matter cannon.

This time, the launch of the tachyon torrent generated an extremely large amount of data. These data include the operation of each component of the negative matter cannon, the reaction during the launch, and so on. By analyzing this data, Xiao Yu will be able to find ways to improve the negative matter cannon, increase its power, reduce its energy consumption and volume, and mass.

"Let's break it down. Of these, 70 percent of the analysis is borne by me, 8 percent is responsible for the Lucca civilization, and the remaining 22 percent is shared by the rest of the races. During the analysis process, everyone should pay attention to collaboration, communicate at any time, and publish any conclusions on the internal forum. ”

Xiao Yu issued such an order. Under Xiao Yu's command, the scientists of the Department of Science, who had grown to nearly 10,000, quickly began their work. They are like screws, contributing seemingly inconspicuous but very important liliang to Xiao Yu's huge machine.

After a little analysis of the data obtained after the first shiyan of the negative matter cannon, Xiao Yu found a very serious problem.

"Shhh...... The damage was too severe. With just one launch of a shiyan nature, the damage rate of its parts reached three percent, and it was completely paralyzed and unable to carry out a second launch. Well, most of the parts are damaged because they are burned because of the high energy loading rate. This again involves the problem of material technology, hey, what a headache. ”

Xiao Yu didn't want to spend so much time on the instrument he had spent so much energy making, but there was no solution at present.

At this moment, the disadvantage of the incomplete development of the technology tree was once again exposed. If all kinds of science and technology develop in a balanced manner, at this moment, Xiao Yu's material technology should be at least two levels more advanced than now. However, Xiao Yu's situation now is that military science and technology and weapon theory have developed to the fifth-level civilization stage, while material technology is still in the pitiful primary stage of the fourth-level civilization.

"Well, the focus of the next step should be to carry out research on materials science and technology at the same time as the research on negative matter cannons. But...... Most of these scientists are talents in military science and technology, and they are not proficient in materials science and technology. Hey, the number of scientists under my command is still too small. ”

Xiao Yu thought about these questions with some headaches. Xiao Yu does not expect these scientists to be generalists in all aspects of science and technology like himself.

The post-launch evaluation of the negative material cannon is in full swing, and Xiao Yu hopes that in this operation, he can find ways to improve it.

At the same time, an evaluation of more than 100,000 new jishu items obtained in this construction operation has also begun. Among them, the most precious and practical is undoubtedly the faster-than-light detection jishu.

Due to the difference in power, the difficulty of manufacturing the tachyon detector is several orders of magnitude lower than that of the negative matter cannon, which means that at this stage, Xiao Yu can already miniaturize the tachyon detection module and equip it on his own spacecraft.

But after really getting the faster-than-light detector jishu, Xiao Yu had deep doubts in his heart.

"Judging from the technological height I can reach at this stage, if I try my best to find it, I can find the curvature sailing ship that is 0.01 light-years away from me. The faster-than-light detection of the Merian civilization must be much higher than mine, and according to the arrival of the support fleet of the Merian civilization a month after I left that star system, I have only just run less than half a light-year away, and there is no reason why they can't find me, and if they find me, there is no reason why they can't come and hunt me down. ”

"Being robbed of the market opened by a fourth-level civilization is too damaging to the reputation of their civilization, and besides, I still have something like alien beast flesh that attracts them, no matter how you look at it, there is no reason why they should not come and kill me."

"So...... Is it because of Weishenme? Xiao Yu fell into deep thought.

"Could it be because of you? Spooky guy. Looking at the strange star that was only half half half a year away, Xiao Yu muttered to himself.

The star was still there, quietly emitting its own light. (To be continued......)
