"Or maybe the group of aliens depicted on these petroglyphs is another group of aliens who came over later? The first owner of the star core was trapped, and then sent a distress signal, and the fellows who were tens of millions of light years away rushed to try to rescue. However, because the spacecraft of the first owner of the star core was damaged, perhaps the spacecraft itself could not send a distress signal, but the first owner of the star core had already established a communication base station in Antarctica that could communicate across the stars when he came to the earth.

Tang Feng smashed his mouth, it seemed that this explanation was more reasonable, but there were also many contradictions in it. Even if the South American tunnel and these petroglyphs were left behind by the second batch of aliens, how could they not find the star core with their technology? Even if the first owner of the star core died at that time, this second group of aliens is supposed to be able to find the star core.

Moreover, the petroglyphs have clearly depicted the appearance of the star core and Australia, which means that the second group of aliens have found the star core, but why don't they take the star core but keep it for themselves?

According to the main program, the star core is the supreme weapon used to control an administrative star, even in such a developed star alliance, it is a rare treasure, so how could the second group of aliens let go of this star core?

Tang Feng stood in front of those rock pictures in a daze, his mind was full of paste, and he couldn't figure out the key links inside.

Ask the star core, the star core doesn't know anything. The star core is different from the main program that has dissipated, the star core is only condensed with the core material of the earth, and of course it will not know what is going on with the Star Covenant, which is tens of millions of light years away.

However, there is one thing that Tang Feng can be sure of, that is, this South American tunnel that makes human beings puzzled should have been dug by a group of aliens from the Star Alliance. And if the estimate is good, in Antarctica, far away, there should be a communication base station left by the first star core owner.

Thinking of the alien communication base station that is likely to contain extremely high-tech, Tang Feng's heart is hot. After all, he is preparing to launch a space exploration program, and if he can use these alien technologies, it will definitely be of great help to him.

"Hmm. Looks like. I have to take some time to go to Antarctica! Tang Feng muttered to himself, but now is obviously not a good time to go to Antarctica, it is April, Antarctica has begun to enter the polar night state, the time window to explore Antarctica has passed, if you want to go to Antarctica, at least you have to wait until January next year.

However, this sudden idea liberated Tang Feng from his state of being in a state of confusion. Shaking his still somewhat dazed head, Tang Feng laughed at himself: "I almost let these petroglyphs go crazy." It seems that the cultivators are still not at home, and the Dao heart is not stable enough! Leave you, don't you want these bad things to happen? Oh, this station actually stood for more than six hours? ”

Tang Feng raised his hand and looked at his watch, he was surprised, no wonder his legs were numb, and his stomach protested!

Taking off the miner's lamp, which was about to run out of electricity, Tang Feng took out a miner's hat from the space and replaced it. That's when I started to look for a way out.

Unless Tang Feng can't find a way out here, Tang Feng will definitely not continue to walk. The four petroglyphs already clearly indicate where the two tunnels lead. You might even find another undersea tunnel to Australia in one of the tunnels!

Tang Feng didn't want to walk along those two tunnels to Ecuador or Antarctica, there was still a big mess of things waiting for him outside, if he didn't get out quickly, it was estimated that he would have to fry outside!

Of course, as long as you can get out, you will have enough time. You can come back here again, and then calm down and explore these two tunnels, as well as the undersea tunnel, and maybe you can find a South America-Australia undersea tunnel that shocks the whole world!

As soon as he thought of going out, Tang Feng's mood became even more urgent. Although those two tunnels are also full of great temptations. Confused, but compared to going out, that little temptation. Confusion is nothing.

Tang Feng walked around the huge underground hall for almost a circle, and finally found a crack in the northern part of the hall that kept pouring wind into it. This crack is about a meter wide, and it will allow Tang Feng to squeeze in, but because of the continuous blowing of some cold and dry wind from this crack, Tang Feng arches in without hesitation.

The bottom of this crack obviously has traces of water washing, which makes Tang Feng even more convinced that this crack can lead to the outside world. Sure enough, the further you walked out, the bigger the crack became, and after about five or six minutes of walking like this, the crack had become two or three meters wide. When Tang Feng came to the end of the crack, he finally saw the sun.

After this crack reached here, the blue sky finally appeared above his head, although it was only a small hole, but this hole five or six meters above the ground was enough for Tang Feng to climb out.

A dry and slightly cool wind continued to pour in from the hole overhead, which made Tang Feng take a few greedy breaths, and then moved a few times, and began to climb up the uneven rock wall.

The height of five or six meters was nothing to Tang Feng, and the uneven rock wall was enough to provide Tang Feng with a place to borrow his hands and feet, so in less than two minutes, Tang Feng successfully drilled out the not very big hole.

It was a very inhospitable area, at least from the north, east, and west, and it could be described as barren, but not far south of the cave entrance, a river was roaring downstream.

There was no one around, and at the very high of the sky, several eagles were constantly circling, seemingly looking for tasty food.

What is this place?

Tang Feng looked around blankly, and then looked at the eagles in the sky. Obviously, for the "behemoth" of Tang Feng, those eagles are not interested, and they are still following a very regular rhythm, constantly drawing circles in the sky.

Shaking his head, Tang Feng first changed the set of clothes when he fell out of the hole, and then took out the GPS locator, only then did he know where he was now!

"Sampras, if you have time, come and pick me up at the Loa River between Calama and Chiučiu in Chile! Lao Tzu came out" (to be continued......)
