Can't hear Lin Yuan's garrulous, at this time the captain mood is finally calm a lot.

Almost ten minutes later, they finally arrived at the location of the cave. At this time, they stood in front of the cave and took a deep breath.

Shandong is a vast area, and you can't see anything at all. Facing the unknown cave, it's like a black hole in the universe. It's so dark that it wants to devour everything.

For black, it always symbolizes fear. Standing in front of the cave, everyone is silent.

Ma Bo was helpless. He was in the same mood as Lin Chong. Standing in front of the mountain, he beat the drum of retreat again. However, he thought that he had just come to the cave from the top of the mountain. He had survived so many fright along the way. As the old saying goes, all come here. What can I do?

At this time, Lin Chong looked at Zhang Liang standing beside him with a bitter smile and joked: "what do you think at that time? How can you dare to go inside such a dark cave with bad weather that day? Are you too bold? "

Zhang liangxiao is very happy. Looking at the dark cave in front of him, he seems very relaxed.

"At that time, I didn't know what to think. Anyway, I just went in, but it's really frightening in retrospect."

Standing in front of the cave, Lin Yuan did not go inside, but stood outside to observe. However, if he only observed outside, he could not see anything strange. Even if he passed by the cave, he would not go inside. One was that he did not know whether there would be any danger. The other was that the cave was too common to be seen According to normal thinking, it's just a little bit dark.

But I can't feel it from the outside. If I enter, I can feel some clues.

Most of the mountains in Zhangjiajie are stone mountains. Lin Yuan touched the wall and found that there are many mineral elements in the stones. If they were mined, they would be good stones.

Due to the special conditions of stratum and structure, the mineral resources in Zhangjiajie are mainly sedimentary minerals, such as coal, iron, nickel and molybdenum, followed by lead, zinc and copper formed by low temperature hydrothermal solution, and non-metallic minerals such as limestone, dolomite, marble, fluorite, barite and silica (quartz). For example, qinganping is rich in marble, coal, iron and mineral water .

Quartz sandstone, which forms the peculiar landform of sandstone peak forest in this area, is also a kind of mineral resources. Its silicon dioxide content is 90% to 99.06%, which is a high-quality raw material for the production of quartz glass.

It is said that in ancient times, many weapons makers liked to come to Zhangjiajie to collect materials.

"Since we have all come, we must go in and have a look. If there is any danger, how can we get out immediately. Since we are going to search for treasure, we must have some spirit of exploration, so let's go in. " After that, he looked at Wang Gu.

Feeling Lin Yuan's eyes, Wang Gu raised his eyebrows and said, "what do you want me to do?"

"Let your people take the lead. Can we just let a few of us go first? We are the key targets to be protected because we have no strength or combat power

After Lin Yuan finished this sentence, Ma Bo next to him nodded fiercely, feeling that what Lin Yuan said was very reasonable.

Wang Gu gave Lin Yuan a cold look. Just when he wanted to say something, the team leader glared at Lin Yuan and yelled, "if I say that, among these people, your martial arts is the highest, you should take the lead!"

It seems that the team leader is determined to find trouble for himself. And when he went down the mountain just now, he was really angry. He would never let go of an opportunity to make himself look ugly.

But Lin Yuan didn't pay attention to him. He just looked at Wang Gu with a smile on his face.

Being watched like this made Wang Gu feel quite uncomfortable. However, at that time, he had already boasted that his own people were responsible for all the injuries. Now is not the time for falling out. He can only endure for a while.

"You'll find your way ahead and leave three people behind. That's it!"

The captain heard Wang Gu's order, and his face was very ugly, but he couldn't disobey Wang Gu's order, so he had to follow it.

The entrance of the cave is four or five stories high, with big stones on both sides.

Walking into the cave, I heard the sound of dripping water. It's dark in the hole. You need a flashlight to see what's going on in the hole. There are stalactites on all sides. Water drops drop down along the stalactite and drop on the ground.

Other people feel that it is rather gloomy around, like a creepy spear in front of the public, every step feels a little suffering.

The shape of stalactites is strange, but Lin Yuan and Zhang Liang are appreciative. Some stalactites are like a conch, which seems to play beautiful music. Some stalactites are like a harp. Some stalactites fall in rows, like curtains.

"In fact, this cave is very beautiful. If it can be developed into a tourist attraction, there will be a lot of tourists." At this time, everyone was very quiet. When Lin Yuan suddenly said a word, many people were shocked."You pull it down quickly. Give me money for this cave. I won't come here. It's so gloomy, and there's such a cold wind. It's really uncomfortable!" Wang Gu retorted.

Lin Yuan smiles. Now he is only less than 50 steps into the cave. He has not yet felt the aura of Zhang Liang.

However, when they continued to walk back, it was obvious that they felt a sense of depression. First, the feeling of depression came from the surrounding atmosphere. It was really too gloomy and quiet. Second, it seemed that there was a lack of oxygen in the cave, or for psychological reasons. They felt a little heavy and jumped very fast.

At this time, Lin Yuan felt that the cave was really strange. There was an invisible magnetic field in the cave, as if there was an eye staring at everyone's every move.

There was the sound of running water in the cave. At this time, all the movement on the field came from the sound of running water and the sound of people panting. Surprisingly, along the way, we found that the ground under our feet was an abnormal certificate, and there were not even a few stones on the road. It was as if they had been dug out by hand and paved the ground.
