Happy New Year! Xiaomo greets the big guys!

At the bottom of this wide ice cap crack is not a flat river, and in some places there will be a lot of ice edges abruptly, and in other places there will be large ice cubes.

It is estimated that these things fell from the ice walls on both sides and then froze on the glacier at the bottom of the crevasse.

However, whether it is those ice edges or ice cubes, they are crystal clear to the outside, and one by one seems to be like the purest crystal. The crack is too deep for the sunlight to shine directly here, but the sunlight reflected off the ice wall makes these ice edges and ice cubes emit an extremely crystalline light, like countless crystal lamps, illuminating the bottom of the entire crack very brightly.

Whenever he encountered these ice ridges or large ice blocks, Tang Feng had to carefully slow down, and sometimes even had to put the snowmobile into the space, then climb over with both hands and feet, and then release the snowmobile to continue moving.

The journey of more than 20 kilometers took Tang Feng nearly two hours before he finally reached the area where the big tunnel was located.

The ice here is already very thin, and at its thickest, the ice is no more than a meter thick. In some places, the rocks are even exposed.

At this point, about 200 meters down, is the large tunnel that extends from South America.

Tang Feng didn't care about anything else at this time, he pressed his hands on the bare rock, and quietly activated the star core, and the next moment, where Tang Feng pressed his hands, a cave with a diameter of two meters suddenly appeared.

The rock formation more than 200 meters thick and the two-meter diameter cave made the star core consume a full 10% of its energy reserves before finally connecting this cave with the big tunnel.

The moment the tunnel was opened, a warm air flow rushed out of the cave. In an instant, a white pillar of spray formed at the exit of the cave.

After all, the large tunnel is deep underground, where the temperature is in the twenties, and the bottom of the crack, although the temperature is close to zero, is colder than the air in the large tunnel, so it is not surprising that this white fog is formed.

The cave opened by Tang Feng is not straight up and down, but a passage that is constantly sloping downward. The angle is about 30 degrees, but the length of the passage is more than 600 meters, and it goes diagonally into the rock formations of the lower part of the glacier, and finally leads to the large tunnel.

Putting the snowmobile into the space and releasing Sanxiao again, Tang Feng took Sanxiao along the passage that had just been opened and walked underground.

The miner's lamp overhead and the strong flashlight in his hand illuminated this two-meter-diameter passage very brightly, and this passage had just been opened. There is no need to worry about any danger inside. Therefore, for more than 600 meters of passage, Tang Feng and Sanxiao walked for about fifteen minutes before entering the wider underground tunnel.

It was very warm inside the tunnel, with a temperature of at least around 20 degrees. It's just that unlike Tang Feng's imagination, although this tunnel is very warm, it is dead and silent, and there are no imaginary paleontocreature at all.

According to what the master program said back then, this tunnel should have been opened by the first owner of the star core. In other words, the tunnel is more than 10 million years old.

The first owner of the star core entered the South American continent through this tunnel. Then the most core material on the earth was collected on the South American continent, the North American continent and the Australian continent, and finally condensed into a star core.

Perhaps because this tunnel is buried too deep, and there is no communication between the two ends, it is difficult for animals from the outside world to enter this tunnel, which makes this large tunnel dead silent.

The tunnel is very dark, and it is best described that you can't see your fingers.

The miner's lamp above Tang Feng's head and the strong flashlight in his hand are the only two light sources in this tunnel.

It's a bit hot in the tunnel. Tang Feng had no choice but to take off his cold-proof clothes, and then slowly walked forward along the big tunnel with Sanxiao.

However, after walking a short distance, Tang Feng found that the ground of this tunnel was very flat, much smoother than the tunnel on the South American continent, so he didn't think much about it. Tang Feng directly released the military Humvee and let the three children get into the car, and then drove the car forward at a speed of more than 20 kilometers per hour.

The headlights of the Hummer are much brighter than the miner's lamp and the bright flashlight, and the two headlights in front of the car are like two sharp daggers, directly breaking through the darkness of hundreds of meters in front of the car and illuminating the road ahead.

The rumbling sound of the engine echoed through the tunnel, and I don't know how far it went. In this way, after Tang Feng drove the Hummer forward for about five hours, an extremely wide underground space appeared in Tang Feng's line of sight.

This space is so large that Tang Feng can't see the edge of the space at all. If it weren't for the fact that the survey function of the star core had not stopped, it would have been really difficult for Tang Feng to figure out the scope of this underground space.

Through the survey function of the star core, Tang Feng could clearly see how large the scope of this underground space was, which exceeded one square kilometer. As for the height of the space, it is more than 20 meters!

This space is dozens of times the size of the underground hall near Calama, Chile!

Tang Feng got out of the car, only to realize that the air in the space was a little stuffy. It is no wonder that this underground space has been formed for at least thirteen million years, and it is estimated that in addition to the first owner of the star core back then, Tang Feng and Sanxiao are the second animals to come to this underground space in these thirteen million years!

Through the survey of the star core, after determining that there was no danger in this space, Tang Feng took out dozens of high-power halogen lamps and generators with confidence, and at the same time took out the cables one by one, and after connecting the cables and halogen lamps, he began to install these halogen lamps everywhere.

Here, these halogen lamps don't need a lamp stand or anything at all, just put them on the ground, every time a halogen lamp is placed, after Tang Feng turns on the switch, this halogen lamp can illuminate the surrounding area of thousands of square meters.

After the installation of dozens of halogen lamps and two generators, almost the entire underground space can be seen.

At this time, Tang Feng found that this underground space was not a flat river, in the middle of the space, a raised platform of about 200 square meters was particularly eye-catching, and above this platform, there was a huge shaft with a diameter of more than 30 meters.

Tang Feng walked to this platform, raised his head and shone upwards with a strong flashlight, but he couldn't see where the top of this shaft was.

You must know that this underground space itself is more than 1,000 meters below the ground, plus the Vincennes Peak overhead, it is nearly 6,000 meters away from the summit of Vincennes! (To be continued.) )
