I don't know how long I walked, Xu Wenjie stopped, he felt that he couldn't go on like this.

From the time he entered here, at his speed, he had already walked a long distance and had not yet seen the bottom of the cave. What surprised him was that the cave had no signs of being excavated, as if it had been formed naturally.

But according to the information he learned, this is impossible, and such a cave should be excavated to be logical.

"It's weird, what the hell is going on, is this really natural."

He took a small hammer and knocked down a stone on the stone wall, and after carefully examining it with the spotlight in his hand, he found that there was no trace on the stone.

Unable to figure out why, he could only take Mickey Mouse and Tourmaline Beast and continue walking towards the depths of the cavern that he didn't know where it led.

One hour, two hours, three hours......

When four hours passed, Xu Wenjie's face had changed, and he no longer had the calmness he had at the beginning. The cave was too deep, a little scary, and he wondered if it was the way to the center of the earth.

Even if he didn't go straight up and down, he could walk dozens of kilometers in four hours at his speed. Based on this distance, it should be at least two kilometers underground.

Moreover, what made him feel strange was that there was actually air here, or circulating air. It was as if the air was coming up from below, and there was a hint of heat in it.

"Is it a volcano? No, if it's a volcano, the air should smell of sulfur. Not a volcano. Could it be an underground river? ”

With their own doubts. Xu Wenjie is ready to continue walking. He went to see where the cave leads. Fortunately, there was enough food in his backpack.

……

In the place where Xu Wenjie disappeared, it was already full of soldiers at this time. It has been more than four hours since Xu Wenjie disappeared, and the faces of the people above changed after learning the news.

"I asked you to protect him, and you played tricks on me. Have you forgotten our rules? Now that the person has disappeared, I think you will explain to the above? A huge roar sounded in the ears of several guys who came with Xu Wenjie.

At this time, they had lost their calm expressions on their faces, and their faces became even more ugly. In the face of the colonel's angry scolding, he could only listen with his head down.

There's no way, when people came, they gave them a few explanations, don't let the people who follow them have an accident. That's good, just a few minutes. The people who let them look at it are gone.

"It's not our fault either, the legs are on him. Are we going to tie him up? A man said in an inaudible voice.

The colonel was immediately angry, pointed at him and said, "You are still reasonable, people have legs, don't you have long legs, you don't know how to send someone to follow him!" And you, I heard that this kind of thing happened because you were not convinced. ”

"I ......"

"Don't tell me that you don't dare to accept punishment and don't dare to talk nonsense. If you can't find out the people this time, not only will you be responsible, but none of the guys above you will be able to escape, hum! ”

With that, he ignored the guys and walked over to the officer who was in charge of the search.

"How's it going, haven't you found a clue yet?"

"We've found some, but we don't know if it's a clue."

"Take me over and see, since people disappeared here, there must be something wrong here." The two of them walked towards the rock wall where Tourmaline and Mickey Mouse had attacked.

"It's here, you see, the traces of these places, as if something attacked them. We analyze that it may be some kind of animal, but what animal can shatter all the stones? ”

The colonel looked at the smashed stones, but he had a different opinion from the officer, what kind of animal can be crushed, the mouse that followed Xu Wenjie can be smashed with his teeth, and the lion named Simba can also do it.

They investigated Xu Wenjie's information very clearly, especially after the appearance of fish and honey, they sent a large number of spies, mixed with those retired soldiers, and sent them to Africa to serve as Xu Wenjie's guard.

It is precisely for this reason that they know how valuable Xu Wenjie is and how significant it is to the country's strategy in Africa.

Through Xu Wenjie's relationship, they have received a lot of benefits in Africa. In particular, the mining of some rare resources, which used to be only available secretly, can now be boldly mined through the mining certificates opened by those countries.

In fact, many countries are cautious about doing this kind of thing, because all countries are meddling in the affairs of Africa, which is the most backward place where human beings live, and where the development interests are greatest.

Just because the continent is undeveloped and poor doesn't mean it's worthless. On the contrary, the value there is very large, because the lack of development indicates that the potential value is great and the respective resources have not been tapped.

The Colonel touched the area where the attack had been taken with his hand, then looked around, and soon found some remaining marks.

He walked around again, and when he noticed that it was strange, he said to the officer, "Use the equipment, and chisel this stone wall for me first." ”

"I'll let someone do it."

The officer knew that although the person in front of him was lower in rank than him, he was a person from a special department and had much more power than him.

The equipment was quickly transported, and a group of people began to excavate the rock wall. The stone walls are hard, but for them there is no problem digging them up.

The generator set was ready, and the drill bit was pointed against the stone wall and drilled directly into it.

"Stop!"

The colonel looked at the situation inside after the stone wall was chiseled, and quickly stopped. Because he has already discovered the difference inside the stone wall.

If they continue to dig like this, it is very likely that the people will not be found, and something will happen to their group.

"Organs? It doesn't look like it can be chiseled. ”

After the equipment was removed, he observed the situation on the ground again, and he seemed to understand something, and then used a wooden stick to draw on the ground.

"You dug me up the stones from there, along the line I draw. Be careful, there may be traps underneath. ”

Then he turned and walked over to the guys who were looking here.

"You go back to me now, and call me those thorns at headquarters. Tell them that this time I want them to complete the big task, which is very difficult, and if you are not careful, you may die. ”

A couple of guys left with the news a little depressed. They did not understand at all what kind of consciousness this colonel had.

Half an hour later, someone suddenly shouted, "Sir, there is a discovery, there is a discovery." ”

Hearing this voice, a group of people instantly gathered over, looked at the exposed hole, and nodded.

For this situation, they had already expected it, but they didn't expect that the mechanism was hidden so deep, more than three meters deep, and it was full of stones, and they didn't know how the ancients did it at that time.

At this time, in the bottomless cave, Xu Wenjie encountered some trouble. (To be continued.) )
