Watching the figures of the four employees disappear into the swarthy hole one by one, Sophia involuntarily hugged Tang Feng's arm.

Feeling Sophia's nervousness, Tang Feng said with a smile: "Honey, don't worry, these employees must not be in any danger, the hole has been exposed a day ago, if there is really any danger below, it should have been revealed in this day's time." Besides, the rope lifter we use can pull these four workers up from below in a matter of seconds."

Before Tang Feng's words were finished, the walkie-talkie rang: "Report, it's very empty and flat below, except for a small dark river, nothing dangerous has been found" When this voice sounded, the mark of the rope happened to be at a position of sixty-two meters, that is, under this hole of more than thirty meters, there was still a space of more than thirty meters deep.

Tang Feng pressed the call button on the walkie-talkie and said, "How is the air situation below?" ”

After a short silence, the walkie-talkie rang again: "The air is very good, but it's a little cold, the temperature here is estimated to be at most seventeen or eight degrees, if you wear a little more, it will feel very comfortable here."

"Okay, you guys wait down there, the wires and lamps will be sent down immediately, after you install the halogen lamp, take a closer look at the surrounding situation, and don't go far before I go down."

"Yes sir!"

Hearing that Tang Feng was going down, Sophia complained and gave Tang Feng a big health ball, Tang Feng smiled and said, "Honey, isn't it already sure that there is no danger down there?" And you hear it too. The temperature down there is very comfortable, and when I figure it out, I'll build you the most luxurious underground palace in the world. ”

Tang Feng still has a talent for coaxing women, Sophia smiled and kissed Tang Feng's cheek, and said in a low voice: "You must be careful, I would rather not go to the underground palace." I want you to be safe. ”

Tang Feng held Sophia's face, kissed it back, and nodded very affirmatively, before turning around and walking towards the entrance of the cave. Under Sophia's gaze, he changed into a piece of equipment, then buckled the lifter on the seat belt, waved his hand at Sophia, and sank directly.

Sophia followed to the entrance of the cave with some trepidation, holding back her fear. Looking down at Tang Feng slowly disappearing into the darkness below.

Upong on the side whispered: "Madam, you really don't have to worry, there is Camilla following below, and with him, Mr. will definitely not be hurt in any way." You can rest assured that Camila is professionally trained. ”

After a pause, Uppong continued: "Madam, in fact, we have lived on the island for more than ten years. It's the first time I've known that such a place exists on the island, so I said. This kind of place, which resembles an underground cave, was not made clear to the outside world before. And as far as I know, there are no large carnivores in the island nation in the southwest Pacific, so it can almost be judged that there are caves below. There should be no animal capable of threatening humans. So, ma'am, you really don't have to worry much. ”

Sophia nodded silently.

In fact, the situation in the underground cave is really similar to what Ubon said. When Tang Feng descended to the bottom of the underground cave, four high-power halogen lamps were already lit up. These four halogen lamps are placed in four directions, illuminating a radius of more than 100 meters.

It's a bit of a misappropriation to describe this place as an underground cave, but to be exact, it's a hollow cave because there are no stalactites like a cave in this cave. It is no wonder that this is a volcanic island, and most of the rocks on the island are extremely hard igneous rocks, and there is no limestone at all, so naturally stalactites will not be formed.

The space is very wide underneath, basically an irregular oval, long from east to west, slightly narrow from north to south, the highest place is almost more than 40 meters, and a dark river only more than two meters wide is flowing quietly from west to east. Under the illumination of halogen lamps, the edges can be seen on the north and south sides, but the edges are not visible at the east and west ends.

However, under the survey of the star core, the situation of the entire underground cavity has long been understood by Tang Feng. In fact, the area of this hollow is far from the extent that can be seen now, and there are longer extensions at the east and west ends.

In fact, according to the information fed back by the star core, the length of this underground cavity is about two kilometers, and about three hundred meters to the west from here is the end of this underground cavity, and this is also the highest point of the entire underground cavity, and the dark river flows out of the rock crevice at the westernmost end of the underground cavity.

The entire underground cavity is generally high in the west and low in the east, so this underground river flows along the underground cavity all the way to the east end, and eventually flows into a large waterhole.

In fact, this underground cavern is a semicircular passage with a diameter of about 100 meters and a length of about two kilometers, and it is obvious that this semicircular passage is a magma tunnel formed during the eruption of the volcano, but I don't know what the reason is, this magma tunnel did not expose the surface, and finally with the cooling or retreat of the magma, it left such a ghostly tunnel.

There were a few employees who followed Tang Feng, and Tang Feng said to Camilla: "You keep an eye here, I'll go to the east to see, if there is anything, let's use the walkie-talkie to contact." But remember, no one is allowed to go east without my orders. ”

Hearing such an order, Camila hesitated for a moment before saying, "Sir, then your safety"

Tang Feng smiled and said, "You don't have to worry about me, I'm carrying this." Tang Feng gestured at the MP5 on his back, and said with a smile: "With it, you don't have to think about my safety, just remember my words, no one is allowed to go over without my order, and you are not allowed to tell your wife, just wait for my news." Do you understand? ”

Camila nodded honestly and watched Tang Feng walk east along the underground river.

In fact, Tang Feng wanted to go to the east alone because he had his plans. The conditions of this underground cavity are really fantastic, so Tang Feng plans to use this underground cavity to do something more meaningful.

You know, there are still 1.6 billion carats of rough diamonds lying in Tang Feng's star core space, and this is a volcanic island, this underground cavern used to be a magma tunnel, and it has the basic conditions for forming diamonds, so Tang Feng plans to place those rough diamonds in the space in this underground cavity (to be continued.) )
