A few people approached the entrance of the cave, but it was so dark that nothing could be seen and there was no sound.

"What should I do?" Everyone, you look at me, I look at you, I have no idea.

"I'll come." Although Yang Wenbin was also very scared, he was the oldest, and he was also the thinnest, and others couldn't get down, so he had the courage to admit it.

"I'll go in and have a look." He said.

"Give you my flashlight, spare. Be careful," Temur admonished.

"Tie this rope around your waist and we'll know where you are. Pulling it is dangerous, and pulling it twice means peace. Pull it three times, and we'll pull it out. Seri Guchun also came up with an idea.

"Prepare another rope, if we know anything about Battle, we can use it." Si Qin said anxiously, and took out a bundle of rope and put it on Yang Wenbin's shoulder.

Tie the rope the thickness of his thumb around his waist, and then take the flashlight, Yang Wenbin was frightened and drilled into the innermost hole that Battle had just entered.

The inside of the small hole was still dark patches. With the faint light of the flashlight, his eyes gradually adjusted to the darkness, and Yang Wenbin slowly crawled forward. The hole was smaller than the one just now, but after walking five or six meters inside, it suddenly opened up, and not only could you stand up straight, but also two people could walk side by side.

"Bar--- ---," he shouted. But there was no response.

"Ba--- ---," he shouted, with increased force. But there was still no response.

After walking along the cave for about thirty meters, there was still no figure. The cave was sloping, and further on, it was a dead end, so I stood up and touched the stone wall, but found no opening to go further.

"Can people still fly, impossible." Yang Wenbin thought about Battle's answer just now, it should not be very far from the entrance of the cave.

"Is there another fork in the road?" He said in his heart.

He followed the path he had come from, touching the stone wall with his right hand, and cautiously walked back, looking for possible forks in the road.

After walking about seven or eight steps, suddenly, the hand touching the stone wall was empty, and his feet slipped, and his body lost his balance, and he made an "ah--" sound and fell. I only heard a "plop" sound, smashed on an object, soft, and made an "ouch" sound.

By the glimmer of light, I saw Battle holding his right leg, grinning there.

"How are you?" Yang Wenbin rolled over and asked.

"Ouch, it hurts me." He said bitterly, "It hurts a lot, it is estimated that the joint is misaligned, and if you smash it again, it will kill me." ”

"Why didn't you squeak when you called you just now?" Yang Wenbin asked angrily.

"How many times do you shout, can you hear it outside?" Battle was not happy either.

"Hi --- hi --- hi ---" Yang Wenbin also shouted at the top of his voice, but he only heard the echo of the four walls, and the sound couldn't be transmitted at all.

"What should I do?" Yang Wenbin was also anxious. Suddenly remembered the rope around his waist, so he tugged at it, and the three people outside also pulled it and connected with each other. Yang Wenbin observed it and found that it was a large hole, smooth on all sides, and it was not easy to climb. Looking up, from the place where it fell, it is estimated to be three or four meters high.

It seems that if you want to climb up, you have to rely on a rope to pull it up.

"Battle, are you alright? Can you use your hands?" Yang Wenbin asked anxiously.

"It's not a big deal. I guess it's a sprain. The hand can be used with strength. Battle lifted his spirits and replied through gritted teeth.

"Great. You go up first. Yang Wenbin untied the rope around his waist, tied it to Battle's waist, and pulled the rope three times according to the prior agreement.

The three people outside pulled the rope together, and Yang Wenbin held it with his hand below and raised his head. Battle cooperated and curled up, holding his head, and was slowly hung up.

The rest is Yang Wenbin himself. It is estimated that Battle will have to walk for a while after going up, so he will use a flashlight to look at the four walls.

Suddenly, I noticed that the stone wall on the opposite side was a little different from the other three sides, except for the same slippery, it felt very flat, as if there were traces of artificiality. There seems to be some handwriting on it.

"How can there be handwriting here", Yang Wenbin was curious, "Is there any secret here?" ”

Hurry up and touch it with my hand, and feel that there are indeed characters on it, and it is not a Chinese character, it is actually crooked.

Slowly groping with my hand along the strokes of the pen, it turned out to be a Mongolian character that I had learned since childhood. Some don't know it, some can recognize it, and it's vaguely the words "Kharqin", "Wangye", and "Wuliangha tribe".

Yang Wenbin was shocked, this ordinary cave actually had something to do with the prince of Khalqin, what secrets were hidden behind this wall?

I touched around this stone wall again, and found that this stone wall is estimated to be two meters high, one meter and five wide, very thick, I can't see how thick it is. There should still be a stone cave in the back.

What's inside the cave, is it gold and silver treasures, or flood beasts, demons and monsters, beautiful women and poisonous snakes?

Yang Wenbin pushed the stone door with all his strength, but he didn't move. It seems that he can't open it, and he can't help but be afraid, worried about the unexpected danger inside.

At this time, the rope around his waist moved three times, indicating that Battle had gone outside, and it was his turn to hang himself.

What to do, tell the secret?

Speaking of which, the friends will definitely be curious, and more adults may be invited, and if they run into greedy guys, this place may be destroyed. Thinking of this, Yang Wenbin suddenly thought of the "Tanglin Treasure Theft Case" he saw a few days ago, so many funeral treasures of the Qing Dynasty were stolen by Sun Dianying's villain, and in the end, he had to be a cultural relics expert to carry the black pot. I can't do this, in case there is a treasure in it, which black-hearted parent leads someone to destroy it, not only did he fail to help the country, but he became an accomplice.

Don't say it, the excitement can't be suppressed, and the chest is like a deer, constantly colliding, up and down. Breathing uncontrollably fast. It's better to wait until you grow up and have the ability to uncover this secret.

Yang Wenbin's heart struggled fiercely. As the rope slowly ascended, I gradually strengthened my faith and kept this secret in my heart so as not to destroy the place.

As he was hung up to the main hole, Yang Wenbin's heart relaxed, and he groped out of the small hole, and when he arrived at the exit, his companions were watching his return.

Battle was lying on the ground, clutching his right leg and moaning. At the same time, he is answering the gossip questions of his companions, telling the process of how he lost his trace.

No need to ask, Yang Wenbin also guessed the process of him falling in, it must be the same as himself just now, he didn't find anything when he went in, and when he came back, he fell into the deep pit in a daze.

The mountaineering was overshadowed by this accident, and everyone's interest was not very high. But it's already halfway there, so I can only hold on, otherwise it will be even more difficult to go down. At the top of the mountain, there is a relatively easy way down the mountain.

The five men set off again, and the three boys took turns carrying the wounded Battle on their backs, and it took a lot of effort to go up the mountain. At this time, it was already noon, everyone was sweating profusely, rested for a while, ate their own dry food, and went down the mountain.

Yang Wenbin concealed the secrets in the stone cave, but he also had incomprehensible doubts, what was there, what was in it, and what those words said.

These doubts grew up with him.
