After Ye Han finished speaking, he ignored Xue Ju, who continued to be confused, and connected a communication to the Tiangong number: "601 called Tiangong, received a clear answer!"
"Tiangong received it, please tell me 601!"
"Tiangong, please scan the target area immediately and calibrate the area with abnormal temperature."
"601, I don't understand."
"You don't need to understand, just do it. The sooner the better... Also, I'm not talking about Area 1, but scanning all target areas!"
"601, I am 104, what's going on?" Gao Kai's voice appeared in the communication.
"104, we found a cave in Area 1..."
"Ant nest?" Gao Kai asked excitedly.
"It hasn't been confirmed yet," Ye Han said.
"Then what do you mean?"
"This cave is steaming out. I thought that if the wolf was hiding in the cave, the temperature inside the cave must be higher than outside. Regardless of whether it is a cave or a mountain cave, there is generally more water vapor than outside the cave. Some caves have
Water source, there was a heavy snowfall last night, and the temperature has not recovered yet. The warm water vapor in the cave jumped out from the entrance of the cave. The fog must have risen, and the temperature at the entrance of the cave should be a little higher than the ambient temperature."
"That makes sense!" Gao Kai's eyes lit up, "I will report to the commander now, and you will immediately arrange for manpower to scout the situation in the cave, and get first-hand information as soon as possible to determine whether there are any wolves in the cave."
"yes!"
After the communication ended, Ye Han let out a long breath: "Get ready to enter the cave!"
Everyone responded in unison, immediately sorting out their weapons and equipment and getting ready to enter the cave.
When Ye Han was communicating with the Tiangong, the last armored vehicle arrived at the scene. Ye Han left half of his men to guard the vehicle, and the rest went up the mountain with him.
The hillside is too steep, and the armored vehicle does not have that strong climbing ability, so it can only drive to the foot of the mountain, and everyone climbs halfway up the mountain on foot.
The shape of the cave entrance is very irregular, the long diameter is almost two meters, and the short diameter is only about one meter. The dark cave goes vertically downwards, and it is impossible to tell how deep it is.
This is not a cave, it's an underground cave.
Ye Han took out a fluorescent stick, broke it twice and shook it a few times. After the liquid in the fluorescent stick was fully mixed, he let go and threw the fluorescent stick into the hole.
The weak light falling rapidly illuminated the cave wall. Ye Han found that the cave wall deep in the cave was very smooth and did not look like a natural formation. He suddenly had some speculations in his heart. He felt that the cave wall did not look like a natural formation. There was a possibility that there were wolves in the cave.
A little more confident.
The fluorescent stick landed on the ground a few seconds later. Ye Han made some simple calculations and calculated that the vertical depth of the hole was almost twenty meters. This height was far beyond his expectation.
But it’s not surprising if you think about it. Wolfworms are typical giant insects with amazing climbing abilities. The vertical hole is not only not an obstacle to the wolfworm, but it may be the first line of defense for the insect nest.
This thought instantly appeared in Ye Han's mind, and he immediately burst into laughter.
All animals in Siberia have been eaten up by giant worms. It can be said that wolves are the overlords of Siberia. Who dares to run wild in the wolf's lair?
Even Ye Han himself didn't notice that he had already determined that this hole was one of the wolf's lairs.
Ye Han took off the rifle from his back, pulled the bolt and loaded the bullet: "I'll shoot first!"
"Chief of Staff, I go first!" Xue Ju immediately jumped into the cave ahead of Ye Han, stretching out his feet to support the cave wall, and the sand washed down and made a rustling sound.
Liu Bin also took the first step, only a little slower than Xue Ju, and jumped into the hole second.
Any of the soldiers who dared to let Ye Han go down first rushed up one after another, but Ye Han stood at attention and shouted: "I order you all to follow me!" After that, he jumped into the hole with his rifle in hand.
He was also pushing his feet against the wall, but Ye Han did not support his legs and use friction to descend like Xue Ju and Liu Bin. Instead, he fell a certain distance and kicked hard on the wall of the cave to slow down his fall.
Just like this, Ye Han kept pedaling left and right, and soon fell to the bottom of the cave.
Xue and Liu, who arrived first, were already on alert with their rifles in hand. As soon as Ye Han's feet landed on the ground, he found that the ground was extremely hard and definitely not soil. However, he had no time to observe carefully and immediately stepped forward and picked up the rifle.
Behind him, the soldiers landed one after another, and soon formed a semicircle with their backs to the entrance of the cave.
The cave was pitch black, and the only light source was the entrance of the cave behind him. With the help of the night vision goggles, he could barely see clearly what was going on inside the cave.
This is a typical underground cave. The terrain is extremely complex. There are stalagmites and pillars everywhere as far as the eye can see, as well as various faults and fissures. Just five or six meters in front of where Ye Han and others are staying, there is an underground cliff.
Ye Han approached the cliff carefully. It was so dark below that he couldn't see anything clearly. He threw a fluorescent stick down. Everyone was shocked to find that the so-called cliff was actually an underground valley. The vertical height of the valley was no less than thirty meters. There was a gentle flow of water at the bottom of the cliff.
The underground river flows gurglingly, and the water vapor rises in the full-color night vision device.
In the cave, a small stream reaches the edge of the cliff and then falls from the sky, turning into a water line and flowing into the river. This scene can't help but make people marvel.
On the top of the cliff, the temperature outside the armor was actually seven or eight degrees above zero. Through the observation of infrared equipment, it was found that the temperature of the river water was no less than fifty degrees above zero. It was obviously not an ordinary river water, but an underground hot spring!
Everyone is familiar with hot springs, but no one has ever thought that rivers formed by hot springs can be found dozens of meters deep underground.
This discovery is really surprising, but there is nothing wrong if you think about it carefully. Hot springs are originally formed by underground water affected by geothermal heat. Only those that flow out of the ground are hot springs, and those that have not flowed out of the ground are all like this.
?
The reason why I am so surprised is just that there are so many people there.
The focus of Ye Han's attention is not the hot springs, but the ambient temperature in the cave!
With this underground river formed by hot springs, the temperature in the cave will never get any lower no matter how low it is. Not to mention allowing wolves to survive the winter, there will be no problem even if people live in it for the winter.
That hole is obviously not naturally formed, and the wolfworm really chose a good place to spend the winter!
Liu Bin came to his senses and asked quietly: "Chief of Staff, which way are we going?"
Ye Han concentrated on thinking. The distance between the two banks of the river valley was about ten meters, which meant that the width of the river was no less than ten meters, and the temperature of the river water was high. Although he did not know the temperature tolerance range of the wolf worm, it was possible to climb under the cliff to cross the river.
It's very small, and other than that, the only option is to continue heading deeper into the cave.
Thinking of this, Ye Han looked into the depths of the cave: "Go inside, make sure you mark it so you don't get lost!"
"Just watch it!" Liu Bin agreed and pulled out his saber with his backhand, "Don't even look at it, let's go!"
The soldiers immediately left the cliff and formed a search formation to search deeper into the cave. No matter who passed by a stalagmite or stone pillar, they would pull out their sabers and carve an arrow on the stone pointing to the entrance of the cave.
