Although Tang Feng has never been to the South American Tunnel, he is in a curious psychology, and Tang Feng has also learned about the relevant information of the South American Tunnel, and of course he has also seen the pictures.

But the South American Tunnel was found in Ecuador and Peru, thousands of kilometers away! But if the passage in front of you is not a large South American tunnel, how can you explain that this is obviously a trace of artificial excavation?

And don't forget, this is the same Andean mountain range as Ecuador and Peru, where the Great South American Tunnel was discovered. Who knows exactly where that tunnel leads, maybe the passage in front of you is an artificial tunnel connected to the South American Tunnel!

Thinking of this, Tang Feng couldn't help but feel shocked, if it can be confirmed that this section of the passage is the South American Tunnel, then it will undoubtedly add countless mysterious auras to this famous tunnel, and the most important thing is that the South American Tunnel can directly lead to the outside world.

Thinking of this, Tang Feng didn't plan to go in to investigate anymore, although there was still a period of time before the agreed communication time with the hyena, if he continued to go deeper, who knew if he could send the information inside? It's better to discuss it with the hyena first and then continue to investigate.

Do what you think. Tang Feng turned his head and walked back, walking and walking, this guy felt that just walking like this seemed a bit unpleasant, and with a wave of his hand, an all-terrain vehicle immediately appeared in the passage.

Yaya, there is a star core space that is hanging, and anything can be stuffed into it.

After the fire, as soon as Tang Feng twisted the throttle, the all-terrain vehicle suddenly let out a roar, and ran quickly towards the exit position with Tang Feng. When he came, he walked for more than twenty minutes, and it was useless to go back for even two minutes, so Tang Feng walked out of this tunnel.

The torches around the camp were still burning, but now Tang Feng's mood was different from just now. Take out the infrasonic communicator. Tang Feng sent several messages to the outside in a row, telling the hyena the news that he had found a tunnel that was very likely to lead to the outside world, and at the same time told the hyena that the people outside should not rescue for the time being, as long as some people were arranged to take turns on duty at the entrance of the cave to ensure that they could receive their own information.

After receiving an affirmative reply from the hyena. Tang Feng then took back all those torches and other things, and after making sure that nothing was left, he drove the all-terrain vehicle towards the tunnel.

The headlights of the all-terrain vehicle are very bright, and they can illuminate the area in front of the tunnel for hundreds of meters, and Tang Feng is not worried about running out of gas, because this guy has stored a full two tanker trucks of gasoline and diesel in the star core space. This gasoline was enough for Tang Feng to drive a terrain vehicle from South America to China

The tunnel was surprisingly smooth, and after Tang Feng drove forward for more than two hours, he came across a collapsed place. There was no way, Tang Feng could only retract the terrain vehicle. Then hike through the collapsed site.

In this tunnel, it is impossible to distinguish between east and west, north and south, and even the compass has failed, and the devil knows why the geomagnetic field here is so disordered. However, judging from the progress of the tunnel, this tunnel should gradually go down, which made Tang Feng a little worried.

When walking through the collapsed area, Tang Feng once paid special attention to the top of the tunnel, and really found some vents, but they were not real vents. Tang Feng can't be sure, and these vents are too small. There's no way for people to climb in.

This collapsed area should have been caused by the earthquake, and in some places the roads had even been blocked, but Tang Feng had a lot of strength, and it was easy to move those rocks, so after more than two hours of busy work, this kilometer-long collapsed area was cleared by Tang Feng and a passage that people could get through.

After drilling through this collapsed area. The scenery in front of him made Tang Feng exclaim, "My Jesus Daddy!" ”

Because what appeared in front of Tang Feng was no longer the regular tunnel, but a huge cave, although it was impossible to take in all the scenery of the entire cave, but on this rock wall close to Tang Feng, it was illuminated by the miner's lamp above Tang Feng's head. The colorful colors reflected above almost dazzled Tang Feng's eyes.

Tang Feng walked in front of the rock wall in two steps, stretched out his hand and touched the rock wall, only then did he determine that this rock wall was all emeralds, of course, in addition to emerald gemstones, there are also a large number of aquamarine, cesium beryl, golden beryl and other colors of beryl.

There is even a beryl mine with such abundant reserves in this tunnel!

The so-called beryl is actually the crystallization of beryllium aluminosilicate. In the beryl family, there is no one more famous than the emerald gemstone. Of course, in addition to emerald gemstones, there are many other colored gemstones in the beryl family, which can lead to different colors because of the different metal ions contained in them.

Like emeralds because they contain chromium ions, the sky blue or sea blue aquamarine because it contains iron ions, the color of the rose-red cesium beryl contains cesium, lithium and manganese ions, the golden yellow, light lemon yellow of the golden beryl also contains iron ions, as for those colorless and transparent beryl, it is called transparent beryl.

The emerald gemstones in the beryl family are known as one of the four precious gemstones, and the other three gemstones are diamonds, sapphires, and rubies, so you can imagine how precious emerald gemstones are.

In fact, in the 2014 Yanjing Ginza International Autumn Auction, as the birthstone in May and the commemorative gem for the 55th wedding anniversary, a 17-carat emerald ring weighing 1.15 million yuan was sold for 1.15 million yuan.

At the Yanjing Spring Auction on June 5, 2012, a 46.57-carat natural emerald and diamond necklace was sold for 1.32 million yuan, and a Tiffany 6.29-carat natural emerald and diamond ring was sold for 940,000 yuan.

At present, in the world, it is recognized that the best emerald gemstones are from Colombia, but most of the emerald gem mines in Colombia are some small veins with a length of only fifty or sixty meters and a thickness of 0.3 meters below, and this beryl vein in front of you not only contains a large number of emerald gemstones, but also the area of this vein is huge, even Tang Feng has never heard of such a large beryl vein.

Tang Feng walked along this cave of 20,000 square meters and found that this beryl vein actually covered the entire cave, how many emeralds does this sister have!

As the saying goes, if you lose your horse, you don't know if it's a blessing, and it seems that the buddies fell in at that time, and it wasn't necessarily all bad. At the very least, isn't this vein going to be Lao Tzu's bag? (To be continued......)
