Yue Yuan finally made a decision: whether or not to build it, as the leader of the civilization, he had to fulfill this responsibility.

The manufacturing instructions were quickly delivered to the engineers, Neutrino Communicator, after familiarizing themselves with them, quickly moved into the component production stage with the cooperation of other departments.

The instruction manual is very detailed, covering everything from the overall framework to the smallest chip structure, with corresponding explanations and detailed diagrams. Humans only need to follow the manufacturing instructions exactly, but since it's something from an advanced civilization, even if humans try to imitate it, it's still extremely difficult.

Many of the materials in the instructions were completely unheard of, and their purpose was unknown. Fortunately, the 'Mining Area Patrol' seemed to have foreseen this situation; the instructions included detailed synthesis steps for those materials whose structures had never been seen by humans before.

These are all manageable.

What baffles humanity are the core components, namely the basic functional components and triggering components of the transmitting and receiving devices.

According to the instruction manual, the Neutrino Communicator is powered by electrical energy, but the transmitter outputs neutrino signals, which is very puzzling.

The manufacturing instructions don't explain why, but based on our own knowledge, we speculate that it's some kind of electroweak interaction mechanism, that is, a mechanism that uses the relationship between Electromagnetic Force and Weak Interaction Force.

However, the specific mechanisms and mathematical formulas by which the signal receiver of this Neutrino Communicator operates remain a black box to humankind.

The so-called black box is like a box whose interior is not visible, with the words "Neutrino Communicator signal receiver" written on it in large characters, and then that box is the Neutrino Communicator signal receiver.

Based on human understanding of neutrinos, these particles are extremely small, uncharged, and have minimal interaction with other matter. Therefore, they can easily pass through the human body, buildings, and even the Earth and the Sun.

Currently, three types of neutrinos have been identified: the Electron Neutrino, the muon neutrino, and the tau neutrino, which correspond to the leptons electron, muon, and tau, respectively. These three types of neutrinos are uncharged and do not participate in electromagnetic or Strong Interactions, but they do participate in weak and Gravity interactions.

The various weak interactions between particles produce neutrinos, and stars are the largest source of neutrinos. Therefore, they fill the universe and travel freely at a speed slightly less than the speed of light.

Based on our understanding of the properties of neutrinos, we believe that neutrino detectors must be large enough. Since the signal receiving end of Neutrino Detection and Neutrino Communicator is essentially the same thing, we naturally assume that Neutrino Communicator must be a very large device.

Like the Super-Kamiokande Detector, its main component consists of a 41.4-meter-high, 39.3-meter-diameter stainless steel cylindrical container filled with 50,000 tons of ultrapure water, which takes two weeks to fill. The inner wall of the container is lined with 11,200 photomultiplier tubes used to detect Cherenkov Radiation produced when high-speed neutrinos pass through the water.

Humans typically use this method to detect neutrinos.

But now this Neutrino Communicator is very small.

When humanity completed it, they discovered it was only the size of a car, yet it contained everything. It was essentially cramming the entire Neutrino Detection station that humanity had previously used into such a small space, including the transmitter that Neutrino Detection lacked.

This is truly incredible for humankind.

It took humans nearly two months from receiving the manufacturing instructions to studying and understanding them, and finally replicating the process to complete the manufacturing.

After the Neutrino Communicator was built, it was not transported to the Hope Command Center for installation, but was placed in a separate equipment room in a compartment.

For security reasons, the Neutrino Communicator was not connected to the Hope network. Instead, several dedicated computers were placed in its equipment room to record the signals received by the communicator, which were then translated by 'Tianhe Light'.

After the arrangements were completed, Yue Yuan led a large group of scientists and many sociology experts to the location of the Neutrino Communicator.

"Chief, the transmitter of the communicator does indeed utilize the principle of electroweak interaction, but the receiver does not use ultrapure water, but a liquid with the chemical formula ********."

As Yue Yuan led everyone into the communication device storage compartment, Zhao Youqin, who had been inside making various line connections for the communication device, smiled and began to explain to him.

He was clearly very happy.

"We've tested it, and this liquid also exhibits Cherenkov Radiation effects, and it's even more sensitive than ultrapure water. What's more amazing is that it can be reused. Well, it should be said that it reflects different Cherenkov Radiation angles for the three types of neutrinos. We just need to apply a pulsed current of a specific frequency to it, and it will return to its original state."

The receiver of this Neutrino Communicator utilizes this effect to achieve information communication. Oh, by the way, we named this liquid Cherenkov Liquid.

Cherenkov Radiation refers to a type of electromagnetic radiation, primarily of short wavelengths, that occurs when an object in a medium travels faster than the speed of light in that medium. It exhibits distinct directionality and strong polarization.

It was discovered by the Soviet Union physicist Bacherenkov. Scientists now name this liquid Cherenkov Liquid, presumably in honor of this scientist.

Zhao Youqin's excitement seemed to still be there. With a ruddy face, he continued, "When we were manufacturing the signal transmitter of the communicator according to the instructions, we also figured out some things. We were able to confirm that the core converter works based on the principle of electroweak interaction, but we haven't figured out the specific mathematical model involved in the conversion process yet. At this stage, we only know that we are manufacturing it according to the instructions. The signal source is also... oh wait, we didn't manufacture it according to the instructions either, because our technology is not up to standard. So we chose an alternative solution, and it seems to be working now."

"Oh? What alternative?" Yue Yuan asked curiously.

"Hey, it's just a miniaturized Fission Reactor. The instruction manual that the 'Mining Area Patrol' gave us uses a miniature Fusion Reactor. We don't know how to build something like that."

"Small-scale Nuclear Fusion? Isn't there any specific detail in the instruction manual?" Upon hearing these two keywords, Yue Yuan's face lit up with joy. He hadn't inquired about the specific technical details, so he was unaware of this.

"No," Zhao Youqin shook his head and sighed, also feeling regretful.

However, nuclear fission can also be a source of neutrinos, so it's not a major issue. Furthermore, the key to Neutrino Communicator isn't actually the neutrino source, but rather the converter that transforms neutrinos into recognizable signals.

That thing is truly Black Technology for humanity.
