Tang Feng asked, "Sir, how long do I have to wait?" ”

Sigman touched his chin and said, "Well, I'm not sure about this." You know, the weather in Drake Passage can be unpredictable, especially during the warmer season. Since yesterday morning, winds of more than 13 have been blowing over the Drake Strait, and the strong westerly wind has even caused some 10,000-ton ships to dock in the harbor to avoid the huge waves in the strait. As a general rule, this kind of severe windy weather usually lasts for one to two days. If we're lucky, we might be able to leave tomorrow morning, but if we're unlucky, maybe we'll have to wait a day. ”

Tang Feng nodded when he heard this, knowing that the weather was not something he could control, for the sake of safety, wait two more days.

Of course, if you have to wait, you can't be idle, Tang Feng excused himself to go to Ushuaia to see the sunset, borrowed a light helicopter from Sigman, and drove directly to Ushuaia, which was more than a hundred kilometers away.

Of course, Tang Feng did not go to Ushuaia to watch the sunset, Tang Feng went to Ushuaia for two purposes, one was to continue to survey the situation of the tunnel, and the other was to go to Ushuaia to absorb the uranium ore buried under the ground of Tierra del Fuego.

Tierra del Fuego's uranium reserves are quite abundant, and among the proven uranium storage distribution areas of mankind, the uranium reserves of the small Tierra del Fuego can be ranked among the top three in the world. However, most of the uranium ore here is located in the mountains of the Andes, which is extremely difficult to mine.

Since you can't mine it, let me use it first.

There are still two star core splits in the star core space, but the enriched uranium purified in South Africa has now been almost consumed by Tang Feng. And this time, since he was going to the Antarctic continent to find out the secret of the star core, Tang Feng had to store more energy, in case he used energy and there were no radioactive elements to absorb. Wouldn't that be a delay?

Ushuaia is only ten kilometers from the border between Argentina and Chile, and most of the uranium mines in Tierra del Fuego are on the side of the Chilean border, but the star core now has an absorption radius of up to 57 kilometers, even in Ushuaia. One night is enough for Tang Feng to convert all the uranium ore in a radius of 10,000 square kilometers into energy storage or high-purity enriched uranium.

Although there is one less star core split in the star core space, the star core can also carry 5,500 tons of highly enriched uranium despite the classification and storage function of the star core body, and the rich uranium ore reserves of Tierra del Fuego Island did not disappoint Tang Feng, after a whole night of absorption and purification, the star core space was once again filled with highly enriched uranium after purification by Tang Feng.

Coupled with the fact that the star core split placed in the Bay of Anegada continuously absorbs radioactive elements from the ocean, although the energy provided to the star core body every day is limited, it is continuous. Therefore, when Tang Feng finished surveying the tunnel, the energy storage of the star core remained at 98%.

Last time, Tang Feng conducted a survey of the tunnel in Karama, and it turned out that because the tunnel made a turn in the area of Tierra del Fuego, Tang Feng did not know what the situation was in the section of the tunnel from Tierra del Fuego to the south. And this survey situation gave Tang Feng a very detailed understanding of this tunnel.

In fact, the big tunnel to the south, after more than 10 million years. By the time they passed through Tierra del Fuego, some of them had been exposed. After all, volcanic seismic activity here is still very frequent. Before the advent of human beings, there may have been one or several extremely strong geological movements here, and then the large tunnel that was originally very well preserved was broken.

Through the star core, Tang Feng could clearly see what the tunnel looked like now.

The tunnel was originally located a few hundred meters or even thousands of meters below the mountain, following the course of the Andes Mountains, at the southernmost point of the South American continent. The tunnel follows the Andes Mountains, makes a big bend to the east, and then plunges headlong into the deep seabed at the southern end of what is now the island of Valliano, about three or four hundred meters from the seabed. It crosses the Drake Passage and eventually rises again on the Antarctic Peninsula, continuing along the Antarctic Peninsula all the way to the South Pole.

However, the tunnel does not end at the South Pole, but abruptly ends at the Elsworthian Mountains in West Antarctica.

To be exact, the end of the tunnel is at the bottom of the main peak of the Elsworthian Mountains and the highest peak in Antarctica, Vincennes at 4,897 meters above sea level!

Tang Feng never imagined that when the first owner of the star core descended on the earth, the first stop was Vincenson, the first peak in Antarctica, and the starting point of the first owner of the star core in the world was also the first peak of Antarctica.

However, the survey of the star core is absolutely not wrong, because the straight-line distance from Ushuaia to Vinson Peak is only more than 3,000 kilometers, and the star core can see the situation of this large tunnel very clearly, therefore, the end of this tunnel is Vinson Peak, which is already a definite thing.

In other words, the end point of Tang Feng's Antarctic expedition is at Vinson Peak, the first peak in Antarctica.

Finding the end of the big tunnel made Tang Feng's heart lift. However, looking back at this tunnel, especially the section below the seabed of the Derek Strait, Tang Feng directly dispelled the idea of crossing the Drake Strait through the tunnel.

Perhaps it was during this period of 13 million years that the tunnel had become somewhat fragmented at the southernmost tip of the South American continent due to strong geological movements, and there were many large holes in the tunnel that could reach the surface, one of the largest of which was at the bottom of a lake called Lake Roca.

Lake Roca is a small lake that straddles the border between Argentina and Chile, in a mountain nest about ten kilometers west of Ushuaia. The lake is small but unfathomable, and many surveyors say that the bottom of the lake is likely to be connected to the outside ocean.

The surveyors were right, the bottom of Lake Roca really connected to the Drake Passage. Because at the bottom of the lake is the South American Tunnel, and this tunnel is not only ruptured at the southern end of the South American continent, but also under the Drake Passage, this tunnel also breaks several large openings. You must know that the deepest part of the Drake Strait is more than 5,200 meters, and the tunnel that passes three or four hundred meters below the strait, once a few large openings are broken, the sea water will directly fill the entire tunnel.

Because of the influx of seawater, the tunnel that runs under the seabed of the strait has become a complete connector, and now the tunnel below sea level is full of seawater, so the saying that the bottom of Lake Roca is the ocean is really true. Because if you enter the Grand Tunnel from the bottom of Lake Roca and follow it all the way south, then you'll be entering the Drake Passage! (To be continued.) )
