The oxygen content in the cave is so low that even the most basic oxygen needed to make a fire cannot be satisfied, and everyone is silent, this should be the destination of our trip. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info is just how to get in, which has become our biggest problem at the moment.

"It's really not good, let's leave a mark here, and when we go down the mountain and return to Qingyang Town, we will purchase some oxygen cylinders and explore again, after all, without oxygen, we will be suffocated to death." Xu Ang suggested, advocating a temporary departure.

"It's a pity, it's all in front of the eye, and it's just gone." The sea disagreed, thinking that there should be another way to enter the cave.

"Don't mumble, listen to me. We had to go into this cave anyway, and as for how to get in without putting our lives in danger due to lack of oxygen, I had an idea. The old ghost's eyes grunted, and he immediately thought about it.

He took Wang Ergou to get busy, because the iron chain helped all of us, a few of us also passively joined in, he first found a bamboo more than ten meters high, with a dagger to cut it little by little, we carried, he borrowed Xu Ang's pistol, took out the gunpowder in the bullet, and sharpened the bullet with a dagger, after being satisfied, he loaded the bullet, under the stunned gaze of our group, he aimed at the bamboo, and at this moment I instantly understood what he wanted to do.

I have to say that the old ghost is very experienced, and the bullets of gunpowder have been reduced, and the density has been reduced a lot. Don't worry about the reason for the strong recoil, so as to ensure to a large extent that the connection points of each section of the bamboo can be opened by bullets, so as not to damage the quality of the bamboo itself, and in this way, this simple breathing device is ready.

"This is a homemade exhaust pipe, if my guess is correct, the large amount of miasma accumulated in the cave should be cleaned up quickly." He seemed to be sure of his own approach, but things were not as simple as he thought.

The function of the exhaust pipe worked, but the results were minimal. After using some modern tools such as visual inspection, tape measure, and measurement, Xu Ang planned to carry out a small area of directional and precise blasting above the cave, so as to completely eliminate the turbid miasma in the cave.

Just do it, Ding Nianci and Xu Ang have all arranged, and a precise directional blasting device with an explosion diameter of about one meter has been arranged, and I have been nervous during this period. I couldn't help but rub my hands.

Bang!

With a roar, the rubble flew sideways, the smoke and dust dispersed, and we successfully blasted a gap with a diameter of more than one meter above the cave, and suddenly a large amount of miasma, as if it had been released, emerged from the gap. At first, I didn't take it seriously, but when the smell became more and more unpleasant, I frowned and looked at the cave at the entrance of the mine, until it was only a matter of time before I entered the cave.

Half an hour later, the smoke had cleared, and we walked in the cave after we were sure that there was no oxygen in it, and the cave was very large, with traces of artificial excavation everywhere, and the ground was littered with ore slag. These also show from the side that hundreds of years ago, this place has been discovered and mined by the Qing Dynasty.

"These people must be dead miners."

"God has given you more than men. There are also women and children who also mine here. Song Jingtong pointed to two skeletons on the ground, one large and one small, and said.

Indeed, the situation inside this cave is very complicated, the bones of men, women and children are scattered on the ground, they all maintain the hideous state before death, and then we find the cause of the death of this group of people, after going deep into the cave for 100 meters, Chuang Ye explored the rock structure, and came to the conclusion that this group of people should have died in the mining accident.

"No one has been here for hundreds of years, and I don't think even Ding Wutong has ever been here." Liu Dongming made a new discovery, in a pile of rubble, he found a wooden plaque, on which clearly wrote the four big characters of Lingdong Mining Bureau, and he had a bottom in his heart, because before coming to Snake Mountain, Liang Yun showed us a place in the geological data, that is, Lingdong Mining Bureau, and another point, Lingdong Mining Bureau is the predecessor of Shandong Iron Mining Bureau. The historical background is very strong.

"Then why did the three elders of the burial pit say that Ding Wutong's treasure was hidden here?" I asked, a little puzzled.

"It's not simple, it's really a pig's brain, it must be Ding Wutong who is in charge of guarding this batch of treasures." Wang Ergou glanced at me and said with some disdain.

"No, my dad should know, but I think there is something greasy in this, maybe my dad knows that there are these treasures, but the only ones who really know the location of the treasures are the three elders of the hidden door, after all, the three of them are higher in the Ding family than my father." Ding Nianci thought about it and said, she didn't want Ding Wutong to carry this black pot for no reason.

There is no such problem in the struggle, as we continue to go deeper, the secrets of the cave are also unobstructed, most of the abandoned mines, mines, covered with dust, there is no trace of treasure.

"Damn, where is the shadow of a treasure, there is not even a shadow of an expensive treasure." The old ghost was a little depressed, if it weren't for the sake of that piece of Hetian jade fat seeds, he would have stopped doing it, at most the heavenly oath had a binding effect on him, and he couldn't cause any losses.

"Don't worry, this is just the beginning." Yanagito patted the old ghost on the shoulder meaningfully. A calm look.

"In this mine, although we have positioned and blasted accurately, we can still feel a sense of suffocation."

"I feel this way, too, like there's some kind of gas in the air." The deeper we went, an invisible sense of suffocation enveloped all of us.

"It's gas!" Ge Dazhuang was the first to find out, and his words made Chuang Ye suddenly realize something.

"Everybody, stand back!" The corners of his mouth rose slightly, as if he knew how to find the treasure.

"I'm here to see what you're up to." The old ghost was a little afraid that the world would not be chaotic and looked at Chuang Ye, according to his request, all of us untied the iron chain and threw it on the ground, everyone left the cave as fast as possible, Chuang Ye opened the backpack and called me and the sea back.

"I said Master Chuang, what are you playing?"

"Don't talk so much nonsense, let you do the work, by the way, the sulfur stone powder is scattered along this abandoned mine all the way to the hole where we came out." Chuang Ye placed a bomb made by Xu Ang in the abandoned mine. The entire bomb fuse was covered with sulfur powder, and slowly retreated.

"What do you want to do?"

"After bombing the cave once, I couldn't see any traces of the tomb in the cave anyway, and that was the only way." Chuang Ye explained, he was helpless, and slowly ignited the sulfur powder.
