The soil on the entire cave wall is very solid and very dense.
It is compacted by the explosives, so that the space created is the robbery cave.
Moreover, the sound of the explosives is not loud, and the power is controlled just right.
It is really high.
I walked away, and Yuelan was also slightly ashamed.
She probably used a shovel to dig out those tombs in the past.
She turned to look at me, slightly ashamed.
No wonder this old man dared to be so confident and declared war with us.
Let's see who it is.
Quick hands.
From this point of view, we really can't beat them.
After firing the cannon three times in this way, the second son fished out the soil.
When the old man saw green brick fragments in the soil, his face was filled with an excited smile.
He said excitedly: "We're here, we've hit the tomb wall.
Erzi, be careful."
"Yeah" Erzi picked up the long steel drill.
The steel drill was made of titanium alloy.
Yuelan also had this kind of steel in her bag.
One was light in weight but very hard.
After reaching the outer layer of the tomb wall, this kind of steel drill is used.
One end has a flat tip, the other end has a conical tip, and the middle handle is hollow, but the force strength is very strong.
The second son tied a rope full of knots to the trunk of a nearby pine tree, and the other end was hung down into the robbery hole.
After pulling it to confirm that it was strong, the second son went down to the robbery hole with a steel drill.
The steel drill is about two meters long and stands vertically downward.
Usually when it reaches the top of the tomb, this steel drill, or a crowbar, or a hammer is used to directly break through the tomb wall.
Ancient tomb walls were either made of bluestone or blue bricks, which were then poured with a mixture of glutinous rice and lime, comparable to cement.
The tip of the steel drill penetrates into the gaps between bricks with incomparable accuracy.
As long as a hole is found, it is a breakthrough.
It is easy to open the robbery hole and enter the tomb.
If the layers of the tomb wall are made of blue bricks, the minimum is four layers, and as many as thirty-six or even sixty-four layers.
If you really encounter such a thirty-six or sixty-layer structure, you have to be careful.
Well, one is too thick and cannot be penetrated by manpower.
The other is that there are too many layers, and it is easy to install kerosene or fire acid between layers, or even other mechanisms.
Therefore, to deal with such high-layer tomb walls, special explosives are usually used.
After the second son went down, the old man used a hand-cranked hair dryer to send oxygen into the cave.
I went over and found that before they came up, they must have hidden these tools somewhere down there.
After they separated from us, they hurried over to get the tools.
As soon as we climbed up the mountain, they couldn't wait to start digging holes. .
The hole is long and slender, and there is not much oxygen underneath.
Steel drilling is a physical activity.
When you move, your body will exercise violently, which consumes a lot of oxygen.
The old man's air supply is actually supplying oxygen, and also Erzi, who was doing manual labor, fanned himself to cool down his body temperature.
There was a subtle sound of the collision of iron and bricks from the cave.
The old man shook the hair dryer and shouted to the second son in the cave: "Second son, do you still have any strength?
If not, come up and look for the wind and let your brother go down."

"It's okay, I can still fight for a while."
Erzi responded.
But before he finished speaking, there was a bang, and the entire Thief Cave was like a spitting gun, spitting out fire several meters high.
The huge air wave lifted the old man five to six meters away and rolled on the ground.
"Dad", the boss of the watchdog saw the old man struggling on the ground and rushed over.
"Leave me alone, save Er Zi." the old man shouted.
At this time, Yue Lan and I looked at each other and rushed towards them.
"You" boss was startled, and was completely confused by our sudden arrival.
We quickly pulled the knotted rope out, but the rope was so light that it was obvious that the second son had fallen into the hole.
Moreover, it was such a big fire.
The flames shot up into the sky like dragons, rising two or three meters high.
"Second son."
The old man cried and rushed over, while the boss hugged him tightly.
Yue Lan and I looked at each other, and the red fire wrapped around our bodies, making both the old man and the boss confused.
I walked to the entrance of the cave.
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 down the cave wall with both hands and feet, and went down little by little.
After I went down, it was very difficult to breathe.
The entire cave was half open, and a stream of gas came out of the cave.
It burned into flames as soon as it came out of the cave entrance.
Fire.
Erzi's whole body was already on fire and was burning black.
I held one of his legs with one hand and climbed up quickly.
After pulling it out, Yuelan and the boss took a huge canvas, the kind that was airtight, and immediately covered the hole.
Then they quickly shoveled dirt and covered the hole to completely extinguish the fire.
Several pine trees nearby were already being roasted by the fire.
If it were any later, they might really burn and cause a wildfire.
After the fire at the entrance of the "Er Son" cave was put out, the old man and the eldest man cried and threw themselves at the charred body of the second son.
The two of them cried loudly next to them, as if they were mourning for their heirs.
We checked at the entrance of the cave.
Although the fire was out, there was still a pungent smell coming out from the gap.
Yuelan and I looked at each other and said, "This won't work.
We have to completely block the entrance of the cave."
Otherwise, if the gas leaks too much and is detected, someone will come here. " "Then let's dig more soil and fill this robbery hole completely."
As Yue Lan spoke, she had already shoveled the canvas and all the soil on it into the hole.
The two of us hurriedly shoveled the soil into the hole.
In the end, we dug directly into the soil on both sides of the entrance of the robbery hole.
It took half an hour to fill the hole.
But a big hole was dug in the whole place, and the traces were obvious.
It is difficult to dig a hole, but it is even harder to fill it.
Yuelan and I were already soaked.
Turning around to look, the two old men had already put the second son's body into a big bag.
The old man was holding it on his shoulders.
The old man turned to look at us.
After being stunned for a long time, he said: "Thank you for today's kindness, old man."

Remember it, we’ll see you later.”
After saying that, one person carried the toolbox and the other person carried Erzi's body and went down the mountain.
Looking at their leaving figures, I sighed and said, "Poor people must be hateful."
"This is called not shedding tears without seeing the coffin.
We have already reminded them, but they thought we wanted to monopolize this fight, so they rushed into the robbery hole and had to die before they could retreat."
Yuelan also sighed.
"Let's go, leave them alone, we have to find the hiding place of the cockroach."
I turned to Yuelan and said.
"Wait, don't you think this fight is suspicious?
Why did it suddenly get so angry?"
Yue Lan asked me.
"There may be a large amount of methane or other flammable gases in the tomb.
When the two sons opened the robbery hole, the steel drill and the tomb bricks may have rubbed sparks and ignited the gases," I said.
Yuelan looked confused, obviously she didn’t quite understand what I said:
