Ye Han said, ignoring Xue Ju, who continued to be confused, and a communication access to Tiangong number: "601 called Tiangong, received a clear answer!" ”

"Tiangong received, 601, please speak!"

"Tiangong, please scan the target area immediately and mark the area with abnormal temperature. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

"601, I don't understand."

"You don't have to understand, just do it, the sooner the better...... Also, I'm not talking about Area 1, but scanning all target areas! ”

"601, I'm 104, what's the situation?" Gao Kai's voice appeared in the communication.

"104, we've found a hole in the ground in Area 1......"

"Ant nest?" Gao Kai asked excitedly.

"Not confirmed yet." Ye Han said.

"And what do you mean?"

"This cave is steaming out, I think, if the wolf worm is hiding in the cave cat winter, the temperature in the cave must be higher than the outside, whether it is a cave or a cave, the general water vapor is more than the outside of the hole, some caves still have water sources, there was a heavy snow last night, the temperature has not recovered until now, the warm water vapor in the cave jumps out from the hole, the fog must be rising, and the temperature at the mouth of the cave should be a little higher than the ambient temperature."

"Makes sense!" Gao Kai's eyes lit up, "I'll report to the commander now, and you will immediately arrange for people to reconnoiter the situation in the cave, get first-hand information as soon as possible, and determine whether there are wolf insects in the cave." ”

"Yes!"

At the end of the communication, Ye Han let out a sigh: "Prepare to enter the cave!" ”

Everyone responded in unison, immediately sorted out their weapons and equipment, and prepared to enter the cave.

When Ye Han was communicating with the Tiangong, the last armored car also arrived at the scene, Ye Han left half of the men to guard the vehicle, and the rest went up the mountain with him.

The slope of the mountain was too steep, and the armored vehicles did not have such a strong climbing ability, so they could only drive to the foot of the mountain, and everyone climbed halfway up the mountain on foot.

The shape of the entrance to the cave is very irregular, the long diameter is almost two meters, the short diameter is only about one meter, and the black cave is vertically downward, and it is impossible to see how deep it is.

Where is this cave, the cave is right.

Ye Han took out a glow stick and shook it twice and shook it a few times, waiting for the liquid in the glow stick to mix well before letting go and throwing the glow stick into the hole.

The faint light that fell rapidly illuminated the cave wall, Ye Han found that the cave wall in the depths of the cave was very flat, not like a natural formation, and his heart suddenly filled with a little speculation, feeling that the cave wall was not like a natural formation, and he might be a little more sure that there were wolf insects in the cave.

The glow stick landed a few seconds later, Ye Han made a simple calculation, and calculated that the vertical depth of the hole was almost twenty meters, which was much more than he expected.

But it's not surprising that wolf insects are typical giant insects with amazing climbing ability, and the vertical hole is not an obstacle for wolf insects, but may be the first line of defense for the hive.

This thought instantly appeared in Ye Han's mind, and then he laughed dumbly.

The animals of the whole Siberia have been eaten by giant insects, and it can be said that the wolf insect is the overlord of Siberia.

Even Ye Han himself didn't notice that he had already identified this hole as one of the wolf worm's nests.

Ye Han took off the rifle behind his back, pulled the bolt and put the bullet on it: "I'll go first!" ”

"Chief of Staff, I'll go first!" Xue Ju immediately jumped into the cave in front of Ye Han, stretched out his feet to support the cave wall, and the sand gargled down, rustling.

Liu Bin also took a step forward, only a little slower than Xue Ju, and jumped into the hole in the ground for the second time.

Which of the soldiers dared to let Ye Han go down first, and they rushed up one after another, but they were stopped by Ye Han with a straight shout: "I order, follow me!" With that, he jumped into the hole with his rifle in his hand.

is also kicking the wall with both feet, but Ye Han did not use the friction to descend by holding his legs like Xue Ju and Liu Bin, but fell a distance and kicked the wall of the cave to slow down the speed of the fall.

Just like this, he kept pedaling left and right, and Ye Han soon fell to the bottom of the cave.

As soon as Ye Han's feet hit the ground, he found that the ground was extremely hard, definitely not a layer of soil, but he didn't have time to observe carefully, so he immediately stepped forward and picked up his rifle.

Behind him, the warriors landed one by one, and soon formed a semicircle with their backs to the hole.

The cave was pitch black, and the only light source was the entrance to the cave behind him, and the night vision device barely saw the situation in the cave with the help of that little bit of light.

This is a typical underground karst cave, the terrain is extremely complex, the sight is full of stalagmite stone pillars, as well as various faults and fissures, just five or six meters in front of the foothold of Ye Han and others, there is an underground cliff.

Ye Han cautiously approached the cliff, it was dark below and he couldn't see anything clearly, threw a glow stick down, and everyone was stunned to find that the so-called cliff was actually an underground river valley, the vertical height of the river valley was not less than thirty meters, and a gentle underground river at the bottom of the cliff flowed through, and the river water rose in the full-color night vision device.

A small stream in the cave flows to the edge of the cliff and falls from the sky, turning into a line of water and flowing into the river, which can not help but make people amazed.

On the top of the cliff, the temperature outside the armor was actually minus seven or eight degrees, and through the observation of infrared equipment, it was found that the temperature of the river was not less than minus 50 degrees, which was obviously not an ordinary river water, but an underground hot spring!

Everyone is familiar with hot springs, but no one has ever imagined that they can find a river formed by hot springs dozens of meters underground.

This discovery is really surprising, but if you think about it, there is nothing wrong with it, hot springs are originally formed by the geothermal action of groundwater, and only those that flow out of the ground are hot springs, and those that have not yet flowed out of the ground, aren't they all in front of you?

The reason why I am so surprised is just that everyone is rare and strange.

Ye Han's focus is not on the hot spring cold spring, but on the ambient temperature in the cave!

There is an underground river formed by this hot spring, and the temperature in the cave is not much lower than that, and it is said that the wolf insects will survive the winter, even if people live in it for the winter, there is no problem at all.

That hole is obviously not a natural formation, and the wolf worm really chose a good place to spend the winter!

Liu Bin, who came back to his senses, asked quietly: "Chief of Staff, where are we going?" ”

Ye Han pondered, the distance between the two banks of the river valley is about ten meters, that is to say, the width of the river is not less than ten meters, and the temperature of the river is high, although I don't know the temperature tolerance range of the wolf insects, but the possibility of climbing to the bottom of the cliff to cross the river is very small, and in addition, the only way to continue to the depths of the cave is to continue to advance.

Thinking of this, Ye Han looked into the depths of the cave: "Go inside, make a good mark and don't get lost!" ”

"Just look at it!" Liu Bin agreed, and pulled out his saber with his backhand, "Don't look at it, let's go!" ”

The warriors immediately left the cliff and searched in search formation into the depths of the cave, and whoever passed by the stalagmite or pillar would draw their sabers and carve an arrow into the stone pointing to the entrance of the cave.
