Before seeing the light source, we first encountered a large number of construction equipment that was piled up in a disorderly manner on the wall of the passage, and the front of the passage began to get brighter and brighter, but this light looked a little strange, because it was not the yellow or white light of the general lighting, but a kind of red light, especially in our eyes, we could actually see a large amount of infrared radiation, that is to say, there was a huge heat source in front of it.

"This is,?" When we finally walked out of the passage, there was a small cave of only a dozen square meters outside, and there were three forks in the cave in addition to the passage we walked into, and in the middle of the three caves, there was a well made of metal, and the light we saw was shot from under the well, and from our eyes, we could see that there was a mass of red erupting above and emitting a huge amount of infrared shots. However, there was a large extractor working at the top of the cave directly opposite the well, so the things that emitted a huge amount of heat radiation did not spread, but were immediately sucked into the extractor and sent to an unknown place.

We quickly walked to the cave, and although we all wanted to know what was underneath the well, we would never rush out to look at it. If it were an ordinary person, the eyes of our dragon clan could see infrared, and infrared is also known as thermal radiation, and it is conceivable that things with high temperature will emit infrared rays. The infrared radiation above the well is so strong that it makes the area completely white in our eyes, so you can imagine how hot the gas coming out of this well is. Our eyes themselves can measure the temperature of the object through the infrared radiation emitted by the object, and now the number displayed on the auxiliary number jù in our eyes has reached 6,000 degrees, and although it will not cause harm for a short time if we stick our heads out, it is not good for our armor after all, so we still can't help but look inside.

Scott pulled out a spherical object from his multi-purpose backpack, and then gently pinched it, and the little thing suddenly snapped open two layers of propellers in the middle. As the two layers of propellers spun at high speed in opposite directions, Scott threw it out, and the thing immediately flew up on its own, and flew above the wellhead with great dexterity, and plunged headlong into it. In fact, that little thing is the miniature reconnaissance plane we brought with us, its structure is relatively simple, but the function is very powerful, it can rely on simple instructions to automatically control the flight attitude and quickly carry out reconnaissance, we can see the real-time picture it transmits synchronously, we can also use it to monitor the surrounding sounds and radio signals, and when necessary, it can even act as a radio relay device.

As the small reconnaissance plane flew into the well, a small window immediately appeared at the edge of our visual screen and played the visual signal transmitted back by the person in the form of a picture-in-picture, but there was no danger in the vicinity now, so we simply moved the picture to the middle of the visual image and enlarged it a lot. Through the lens of the Guò people, we can clearly see the environment below the well, it turns out that there is a hot lava river flowing dozens of meters deep under our feet, and the well leads directly to the top of the lava river. After the person flew out of the well and reached the top of the lava river below, the immediate brake began to fly downstream in the direction of the river, but after flying for a total of more than ten meters, he suddenly fell into the lava river and quickly turned into a black mass and slowly disappeared into the river.

"No, the temperature down there is too high, and the reconnaissance plane can only hold on for so long."

Scott said.

"Forget it, it's unlikely that anything will be stored at that temperature, and even if the Americans hide any secrets here, they won't be hidden in the lava."

"That's right."

"Which of these remaining passages shall we take?" … Xiao Chun asked.

"Try which side is passable." I said.

Vina walked up to one of the holes and sent out a low-frequency sound signal, and we heard the echo without her speaking. Obviously, the first test was a passage to the outside, and then the next few were all the same, and it seems that this method is useless. In the end, we could only choose a random one and plan to take a look first, anyway, we dragons can know exactly how far we have traveled and how many angles we have turned, and this kind of thing will not work for us. As we walk through those passages, our brains are already building a set of passage maps synchronously, and once we go through them, we will never walk through them again.

It soon became clear that although the passages had separated from the cave with the lava well, they had all come together and become a relatively wide passage. However, unlike the previous three bifurcated passages, this one does not look like an artificial passage at all, but seems to be natural. The walls on both sides of the passage look like the original natural walls, and the head to the fourth seems to have been treated with some rocks, as if some rocks have been cut off, and we estimate that the large tow is for ease of passage.

The situation on the ground is similar to that of the walls on both sides, which are all naturally formed, and it seems that there may have been a lava pipe before.

After a short walk along this strange passage, we found that the passage began to slope downward, and it became steeper and steeper, but not to the point where we could not walk.

After walking down the passage for more than a kilometer, the front suddenly became open again, but the sight in front of us completely stunned.

What we see before us is not some river of lava underground, nor is it any strange geological environment, nor is it a research base for the Americans. What appeared in front of our eyes turned out to be "Fourth Special District? ”

The technology of Longyuan is very different from the technology of this era, and we are a lot ahead of others in many aspects, especially in military technology. Although it has been more than 2060 years now, civilian technology is actually very simple, and there is nothing too exaggerated, but Longyuan's technology has advanced to the point where it is beyond the scope of normal people's understanding. If Dragon Yuan now fully displays his technology in front of the public, many things will even be regarded as supernatural forces rather than technology, as if we can move objects with the help of electromagnetic force fields, and in the eyes of ordinary people, it is a superpower, which can move objects with thoughts. Also, we dragons can communicate with each other by radio, which in the eyes of ordinary people is telepathy. We still have a lot of such technologies, which are basically completely out of the existing scientific system, and many things do not even have corresponding theories, but the physical objects that can be used directly have been created.

The main reason for this is the Fourth District, the alien warship that crashed on Earth. Although Longyuan has also researched a lot of things himself, in general, Longyuan's scientific and technological personnel are not doing technology research and development, but doing reverse engineering analysis. We are dismantling and studying the existing items on the alien battleship, analyzing the technical principles and using the technology we can achieve to reshape the technical achievements of those aliens little by little, and finally we have the current technical system of Longyuan. However, now, right in front of us, there is a spaceship that is almost exactly the same as the Fourth Special Region we saw at the beginning. Actually, the thing I see now has nothing in common with the Fourth Special Region in detail, but the reason why I am sure that it is the same type of existence as the Fourth Special Region is because of their size. This thing is almost the same size as the Fourth District. In the huge underground cavern that can barely see the ends of the earth**, the terrifying battleship lies on the ground like a sleeping beast, even knowing that it is a metal wreck that has not been touched for tens of thousands of years, the terrifying pressure still makes us feel suffocated.

"Why does the United States also have an alien warship?" Vina said in surprise as she looked at what was in front of her.

"There's only one explanation." Ling said: "There may have been more than one warship that crashed on the earth at all, maybe there is something similar hidden somewhere in Europe or Africa.

It seems that the frequency of alien visits to Earth is much higher than we expected! ”

"Anyway, this thing is priceless, I just don't know if we can get something from it." I watched the huge battleship there in a daze. To be honest, I really wanted to move this thing back to China in its entirety, but that was obviously impossible. Let's not say that the Americans disagree, even if the Americans fully cooperate with us, it would be an unimaginably huge project to transport such a large thing to China on the other side of the world, even if it is moved to the ground. However, even if you can't move out entirely, it's always possible to make some gains. Long Yuan has analyzed so many technologies from the Fourth Special Zone, and it is impossible for the Americans to have no progress on this thing at all, so they must also have a lot of successful technologies that we don't know about.

Scott looked at the giant beast in front of him and sighed: "I finally know why the American artificial mask base needs to be repaired so strangely, it turns out that it is simply a layer of camouflage." The Americans are covering the ship below with an entire base. ”

"If it's to cover up this thing, it's worth the extra investment." I looked in all directions of the huge space and found that there were actually quite a few people here, but the space was too big, and those people were mainly scattered on the surface of the spaceship, and they didn't notice us here. Although the population of the United States is not small, it is still an order of magnitude worse than China. There are more than 100,000 regular professional researchers in China's Fourth Special Zone alone, and all kinds of auxiliary staff and security personnel are even more terrifying, but there are obviously not so many people in this base of the Americans, after all, not everyone can come to work here to hide such a big secret, especially in the United States, which believes in the spirit of freedom, and most people cannot endure this kind of working environment that is almost like being in prison. However, the situation of the Americans has given us a good opportunity to start. I won't leave this time until I go back.
