I went, Ye Luan was also slightly embarrassed, those tombs before, it is estimated that she was beaten with a shovel, she turned her head to look at me, a little embarrassed, no wonder this old man dared to be so confident, declare war with us, and say to see who is fast.

In this way, we are really no faster than them.

After firing the cannon three more times, the second son fished out the soil.

The old man saw that there were green brick crumbs in the soil, and his face was filled with an excited smile, and he said excitedly: "It's here, it's touched the tomb wall, second son, you be careful." ”

"Hmm!" The second son picked up the long steel drill, the steel drill is titanium alloy, Ye Luan's bag also has this, one is light weight, but the hardness is very good.

After reaching the outer layer of the tomb wall, this steel drill is used, one end is a flat tip, the other end is a conical tip, the middle handle is hollow, but the force is very strong.

The second son tied a rope full of knots to the pine trunk next to it, and the other end hung down into the thief hole, and after making sure that it was strong, the second son took the steel drill and went down the thief hole.

The steel drill is about two meters long, standing upright down, and generally above the tomb, this steel drill, or crowbar, and hammer are used to directly smash the tomb wall.

In ancient times, the tomb walls were either bluestone or blue bricks, and then poured with a mixture of glutinous rice and lime, which was comparable to cement.

The tip of the steel drill is extremely accurate and pierced into the gap between the bricks and bricks, as long as you find an opening, then it is a breakthrough, and it is easy to open the hole and enter the tomb.

If the tomb wall layer is made of green bricks, the least is four layers, and the most can reach thirty-six, or even sixty-four layers, if you really encounter this kind of thirty-six or sixty layers, then you have to be careful, one is too thick, and manpower can't penetrate it at all.

The other is that there are too many layers, and it is easy to set up oil or acid between the layers, or even other mechanisms.

Therefore, to deal with such a high number of floors, special explosives are generally used.

After the second son went down, the old man took a hand-cranked hair dryer to send oxygen to the cave.

I went to go, before they came up, they must have hidden these tools somewhere below, and after separating from us, they hurried over to get the tools, and before we could touch the mountain, they couldn't wait to start digging holes.

The thief hole is slender, there is not much oxygen at the bottom, and the steel drill is physical work, as soon as it moves, the body is a strenuous exercise, oxygen consumption is particularly large, the old man is actually sending oxygen, and there is a fan to do physical work to lower the body temperature.

There was a subtle sound of the collision of iron drills and masonry in the cave, and the old man shook the hair dryer while reading the second son in the cave and shouted: "Second son, if you still have the strength, if you don't, you come up to look at the wind and let your brother go down." ”

"It's okay, we can fight for a while." The echo of the second son.

But before the words were finished, there was a bang, and the entire thief cave was like a spitting gun, spitting out a fire several meters high.

The air wave swept the old man out five or six meters and rolled on the ground!

"Daddy!" The boss who looked at the wind saw the old man struggling on the ground, so he quickly rushed over!

"Leave me alone, save the second son." The old man shouted.

At this time, Ye Luan and I glanced at each other and rushed towards them.

"You guys!" The boss was startled, stunned by our suddenness.

We quickly pulled the rope that tied the knot out, but the rope was fluttering, obviously the second son had fallen into the hole, and it was such a big fire, the flames were like dragons, rising into the sky, two or three meters high.

"Second son." The old man cried and rushed over, but the boss hugged him deadly.

Ye Luan and I glanced at each other, and the red practice fire wrapped the whole body tightly, and the old man and the boss were stunned.

I walked to the entrance of the cave, and although the fire was strong, I couldn't feel the temperature, because the red fire was stronger than the fire.

After I squatted down, I climbed the cave wall with both hands and feet, and went down little by little, after going down, it was quite difficult to breathe, and the whole thief hole was half-clear, and there was a stream of gas stringing out of the hole, and it burned into a fire as soon as I got out of the hole.

The second son was already on fire and blackened, and I grabbed one of his legs with one hand, and then quickly climbed upward.

After pulling it out, Ye Luan and the boss were holding a huge canvas, the kind that is impermeable, and covered the hole at once, and then quickly shoveled soil and covered the hole to completely extinguish the fire.

A few pine trees next to it have already been roasted by the fire, and if it is a little later, I am afraid that it will really burn and cause a mountain fire.

After the fire at the entrance of the "Second Son" cave was extinguished, the old man and the eldest screamed and threw themselves at the charred corpse of the second son.

We checked at the entrance of the cave, although the fire was extinguished, but there was still a pungent smell coming out from the gap, Ye Luan and I looked at each other, and I said: "This is not good, we have to completely block this hole, otherwise once this gas leaks too much and is monitored, someone will come here." ”

"Then let's dig more soil and fill this hole completely." While Ye Luan was speaking, he had already used a shovel to get all the canvas and the soil on the canvas into the hole.

The two of us hurriedly shoveled the soil and sent it to the hole, and even in the end, we dug the soil on both sides of the entrance of the hole, and it took half an hour to fill the hole.

But a large pit was dug in the whole place, and the traces were obvious.

It's hard to dig a pit, it's even harder to fill a hole, Ye Luan and I are already soaking wet.

Turning his head, the old man and the two had already put the body of the second son into a big bag, and the boss put it on his shoulder, and the old man turned his head to look at us, and was stunned for a long time before saying: "Today's grace, the old man has written it down, and we will have a date later." ”

After saying that, one person carried the toolbox on his back, and one person carried the body of his second son down the mountain.

Looking at their departing backs, I sighed and said, "There must be something hateful about the poor man." ”

"This is called not crying when you don't see the coffin, we have already reminded them, but they think that we are going to swallow this bucket alone, so we will rush to steal the hole, and we have to die to retreat." Ye Luan also sighed.

"Let's go, leave them alone, we'll have to find the ash's hiding place." I turned my head to Ye Luan and said.

"Wait, don't you think this bucket is suspicious? How could there be such a big fire all of a sudden? Ye Luan asked me.

"This may be that there is a large amount of methane gas or other combustible gas in the tomb, and when the second son opened the robbery hole, it may be that the steel drill and the tomb bricks sparked and ignited these gases." I say.

Ye Luan's face was inexplicable, obviously she didn't understand what I said!

Although she didn't understand much, she suddenly asked, "Then why is there so much gas?" This is obviously not normal! This gas should be similar to the one we burn when we eat hot pot, right? ”
