The Nautilus has an amplifier on it that can increase the function of the star core by up to 500 times in a short period of time.

The detection range of the fourth-level star core is 10,000 square kilometers, that is, a circle with a radius of about 57 kilometers. But with the help of the amplifier, this detection range quickly expanded to five million square kilometers!

Of course, this level of amplification is extremely energy-consuming of the star core, and Tang Feng didn't intend to detect other places at all, so Tang Feng directly narrowed the scope of the amplification, but directly applied the amplification to the survey depth.

Before the use of the amplifier, the detection depth of the fourth-level star core was 20 kilometers, and the radius of the Earth was about 6370 kilometers, that is, in order to detect the center of the earth, the amplifier needed to increase by about 319 times!

This multiplier almost makes the energy storage of the star core consume at a rate of 1% every two seconds.

This is a rather terrifying consumption rate, that is to say, if you simply calculate the current energy storage of 99% of the star core, in the case of a 319 times increase, the energy storage of the star core can only last for 198 seconds!

Of course, in the space of the star core, there are more than 5,000 tons of high-purity enriched uranium, and these more than 5,000 tons of enriched uranium can double the time that the star core lasts! This allows the core to hold out for seven minutes.

In addition, with a 318-fold increase, the absorption rate of radioactive elements contained in the surrounding ocean is also greatly increased. You must know that in the sea near Sansha, it contains extremely rich radioactive elements, such as the total content of uranium in seawater is as high as 1.5 billion tons, and uranium nuclear energy is equivalent to the power generation of a 250,000 kilowatt power station for 15 billion years; The reserves of deuterium nuclear energy are equivalent to the 750 billion years of electricity generated by a 250,000 kilowatt power station.

Although it takes time to absorb radioactive elements in seawater, with a 318-fold increase, the star core is within seven minutes. The absorbed radioactive elements can still increase the time for the star core to hold on for another three minutes.

In this way, after Tang Feng used all the means, he could make the star core last for ten minutes at a 318-fold amplification state.

Tang Feng didn't know if these ten minutes were enough for the star core to absorb those three key elements in the center of the earth, but in the current situation, Tang Feng had no other way to absorb the matter in the center of the earth. I can only try it this way.

At this time, Tang Feng finally understood Andro again. Fan. Why didn't Alexander use the Nautilus to absorb critical substances from the center of the earth in the first place, but drove the damaged spaceship to the center of the earth himself. Although this amplifier is very safe, the energy required is terrifying.

At that time, Andro. Fan. Even if Alexander condensed the star core, how could the star core in that state provide such a huge energy consumption to the amplifier? Probably Andro. Fan. It was precisely because of the lack of star core energy that Alexander had no choice but to go to the center of the earth.

Shaking his head, Tang Feng shook the thought that suddenly popped up, this is not the time to think about those things, this is the time to need to go all out to absorb the core substance of the center of the earth. There is no room for distractions!

In the state of 318 times increase, the structure of half the earth suddenly appeared in front of Tang Feng.

Tang Feng can bet that he is definitely the first person on this planet to have such a complete and intuitive view of the internal structure of the earth, and it is estimated that no one will be able to observe the internal structure of the earth so completely and intuitively for a long time.

As we all know, the earth is like an egg, the core is the yolk, and the mantle is the egg white. And the earth's crust is the eggshell.

This is a very accurate description. At least Tang Feng now seems that the whole earth is really like an egg. According to the results of the survey of the star core, the outermost layer of the Earth is the crust with an average thickness of 17 kilometers, and from the holographic projector, the black crust looks like a solid eggshell, protecting the mantle, which has become soft due to high temperatures but is made of dense rock-forming material.

The thickness of the Earth's mantle is about 2,865 kilometers. It is the largest and most massive layer in the interior of the planet. Because of the high temperature of this layer, the dense rock-forming material and rocks are in a semi-melted state, and the color is also an orange-red.

Below the Earth's mantle, it is 31.5% of the Earth's mass. It accounts for 16.2% of the Earth's volume, and the temperature exceeds 6,000 degrees Celsius.

According to the analysis of the star core, the core of the earth is mainly composed of a large density of iron and nickel, as scientists speculate, but it can be clearly seen that the core is divided into two layers, the outer layer is a substance between solid and liquid, and the core part is solid.

Tang Feng glanced at the data given by the star core, and found that in the outer layer of the earth's core, the pressure here was as high as 1.3 million atmospheres, even the hardest diamond was no different from butter here, and as for the pressure of the core, it was as high as 3.6 million atmospheres!

This is the inner workings of Mother Earth.

However, to Tang Feng's surprise, when the star core surveyed the earth's core, in the middle of the survey range, that is, at this stage in the upper layer of the mantle, the star core actually surveyed the existence of extremely rich radioactive elements.

The radioactive materials here are so abundant that they can allow Tang Feng to survey the center of the earth and absorb the radioactive elements in this area over and over again.

And the energy provided by the radioactive elements here is enough to extend the time of the star core for more than ten minutes!

This unexpected discovery made Tang Feng a little overjoyed, you know, the radius of the earth's core alone is as high as 3470 kilometers, if you absorb the key elements needed in such a huge sphere, the ghost knows how long it will take. In order to ensure that the star core can smoothly absorb the three key substances in the earth's core, the length of time the star core lasts has undoubtedly become the most important key factor.

However, what made Tang Feng a little relieved was that when the survey range of the star core was extended to the center of the earth, the star core immediately issued a prompt: "Key elements have been found, do you absorb them?" ”

Does this need to be asked? After Tang Feng rolled his eyes, he directly gave a definite answer - absorption! Absorb it with all your might!

Tang Feng didn't know those three substances, he really didn't know, at least on the periodic table, there was absolutely no existence of those three elements. Obviously, in the depths of the earth's interior, there are still a large number of new elements that have not been discovered by human beings, but unfortunately, in terms of current human technology, these elements are not yet able to be mastered by human beings!

Time passed by second by second, and the three progress bars that showed the progress of absorption were also constantly climbing upward. After about five minutes, the three progress bars reached full capacity almost in no particular order, which meant that the last three core substances of the star core had finally been replenished!
