Chapter 52 Found it

Michelle and Luo Shaohua both thought of the target location at the same time, but this guess was too bizarre. The temperature inside a star is indeed not high compared to a spacecraft reactor. The smelting of many level 5 high-energy alloys requires high temperatures of over one million degrees and the use of many auxiliary equipment. Level 6 high-energy alloys require much more stringent conditions.

But there is a problem. It is unreasonable to talk about quality without talking about quantity.

The radius of the core region of a yellow dwarf star is about one-fourth of the star's radius. This is the star's energy source. Here the star undergoes nuclear fusion reactions, hydrogen continuously combines into helium and generates huge amounts of energy. The temperature of the star's core is the highest in the star, reaching 1500 million degrees Celsius.

The area extending outward from the core of the star to 70% of the star's radius is the radiation zone, where the radiation generated by the core is continuously absorbed and emitted by matter.

Therefore, it takes tens of thousands of years for photons formed in the core to reach the surface. The star seen by the naked eye is actually a very old star. The temperature of this area ranges from 200 million to 700 million degrees Celsius, and the temperature gradually decreases as it moves away from the core.

From the radiation zone to the star's surface is the troposphere (there is also a very thin differential rotation layer in the middle), which is connected to the star's surface. The hot and cold substances on the star convect here, and energy is transferred from the inside to the outside.

The photosphere is the surface of a star that can be seen with the naked eye on Earth. It is about 500 kilometers thick. The star regions above and below it rarely radiate visible light, so the naked eye can only see the photosphere.
The temperature of the star's photosphere is about 5500 degrees Celsius. In addition, sometimes there are some sunspots on the surface of the star, where the temperature is relatively low, only 3000 to 4500 degrees Celsius.

The chromosphere is the atmosphere of a star, located 3000 kilometers above the star's surface, with a thickness of about 2000 kilometers and an average temperature of about 4600 degrees Celsius.

Above the chromosphere is the corona, which extends millions of kilometers into space. It is the outermost atmosphere of the star, where temperatures reach 100 to 200 million degrees Celsius.

This is not a temporary temperature, but the temperature that the star generates every minute and every second. At this temperature, no civilization below level seven can maintain an artificial building in a star for a long time. No matter how excellent the energy conduction alloy and energy extraction and conversion device are, there will always be a limit. Once the limit is reached, it will be vaporized by the high temperature of the star and become a part of itself.

"It shouldn't be like this. Even the photosphere with the lowest temperature is over 5,000 degrees Celsius. The larger the volume, the stronger the impact it will withstand, not to mention it has to offset the huge gravitational pull from the interior of the star. How could the Tok civilization, an ordinary level five civilization, have the technology to build such a thing?" Luo Shaohua asked aloud. This inference was too outrageous. He would rather believe that there was no hidden base of the Tok civilization in this star system.

"Whether it exists or not, we'll know after we investigate. But you're right, even if there is a safe house inside a star, it can't be that big, and I doubt it can last too long. It might be arranged according to the cleansing time." Michelle ordered the fleet to move forward and head towards the star as a whole.

Li Minhua and his partner, who originally suspected that this coordinate point was just a smokescreen because they could not find the hidden base of the Tok civilization, were ready to leave with the fleet and hurry to the next suspicious coordinate point.

The sudden move of the Star Fleet heading into the interior of the star made the two of them hesitate. Could it be that this guy discovered it but didn't share it with them?
"Commander Michel, have you discovered anything?" Julian felt that the other party must have discovered something, so he simply sent a message to ask the other party. If the other party was so weak and yet dared to take advantage of the situation, then it was no wonder that he was so ruthless.

"I have some guesses, but nothing has been confirmed yet. We are now heading in to investigate the situation," Michelle responded.

"You are heading to that yellow dwarf star. Could it be that Commander Michel believes that the Tok civilization has the ability to build a security center inside a star as a hidden base?" Julian watched the Star Fleet leap to the long-range orbit of the star. He laughed angrily when he heard the other party's answer. Are they taking him for a fool? Li Minhua also shook his head secretly. As expected, he was born in a small fleet and had no common sense at all. How could the alloy material of the fifth-level civilization withstand a nuclear explosion continuously? The high temperature alone could melt it into an ion state and eventually sink into the interior of the star to become a degenerate matter.

"Let's go. Just leave a few detectors here. Don't waste any more time. The high-dimensional interference is about to lose its effectiveness." Li Minhua was too lazy to waste more time waiting and urged Julian to hurry to the next coordinate point.

The two fleets didn't even say hello, just dropped a few probes and jumped out of the star system.

"They're gone." Luo Shaohua was looking forward to seeing their expressions when they saw that there was really something inside the star. The previous cooperation was only effective when both parties worked together. Now that the other party has left, it is equivalent to voluntarily giving up the distribution of related interests. Now whatever they find is theirs, of course, the prerequisite is that they can keep it and take it back.

"All escort-class battleships and destroyer-class battleships disperse and conduct a detailed exploration of the surface of the star within 500 kilometers." Michelle just glanced at the departing fleet and then went about his own business. After all, some things were just their guesses and might not be true. It would not be good to be happy too early.

Hundreds of warships sailed to a relatively low temperature location outside the corona, dispersed, turned on the maximum power of the detection radar, scanned the interior of the star in a direction, and slowly conducted a dragnet-style inspection.

Since a large number of fusion reactions occur inside stars every moment, energy detection is basically impossible, so they can only be explored through neutrinos with the strongest penetrating power.

"It's a pity that if the spectral information is not processed, we can verify whether there is something inside the star just by scanning the spectrum." Wu Shuhe said with a sigh.

Shirley rolled her eyes at him speechlessly. "What good things are you thinking? Starspots and flares are so frequent that even a little abnormality can be easily overlooked."

"That's true." Wu Shuhe had to admit that Shirley was right. Compared with the size of a star, the size of a man-made building is almost negligible, and the spectral range affected will naturally be very small. Under the influence of natural reactions such as stellar sunspots, it is nothing short of a pipe dream to want to find the other party through the obscured spectrum.

After searching for two days in a row, the regional channel frequently received information that the fleet had found the hidden base of the Tok civilization and was attacking it. However, they had just explored one-third of the surface of the star, and there was no sign of the hidden base.

Two days later, the fleet of Tok civilization is one step closer to getting rid of the high-dimensional interference. There are signs that the black ball in the space layer has been knocked out through the interference of force. Once it appears in the void, it will be blown up quickly. The high-dimensional interference without constraints will naturally dissipate quickly.

"Look, is there something wrong with the material reaction in this area?" Another day later, Wu Shuhe excitedly asked Shirley with the detection data. He had only suspected it at first, but now that the data appeared, it was true.

Shirley took a look and the data showed that when the neutrinos penetrated the surface of the star, they were interfered by unknown matter, causing the penetration process to be slightly hindered and it took more time to penetrate the star.
