In the first one or two decades, although there were controls on nitroglycerin, it was definitely not as strict as it is now. As long as you were willing to spend money, you could get it without any certificates.
Nitroglycerin is diluted to a few tenths of a percent and can be used as medicine to treat heart disease. The higher the purity of the original solution (the yellower the color), the more explosive it is. The engineer used the second-level original solution (the purest first-level solution).
).
If anyone wants to give it a try, just pour a few drops into the palm of your hand, no need to apply it, just slap your hand hard and it will disappear.
This is called collision detonation. There is another way of detonating, which is the trick used by Master Ji. It was also a trick commonly used by people in the industry at that time, called side-drug detonation.
With the headlight shining on him, Master Ji first stuffed the two prepared balloons into the little eyes. This process was very slow and he was careful throughout.
"Okay, give me one of your cannons."
After hearing this, Brother Yu gave him an old-fashioned detonator.
The engineer spotted the location and started cutting the lower part of the detonator with a knife.
"This is a side medicine. It will explode with a small force when it comes into contact with fire. Use this as a primer to detonate nitroglycerin."
As he spoke, he poured out some black powder from the lower half of the detonator, tore open a bag of balloons again, and poured the black powder into the balloon.
With a strong exertion, the balloon was pulled up as far as it would go.
At this time, he took out his lighter and said, "Everyone, get out quickly. It's very dangerous."
"good."
People started to drill out.
"Young man, please stay for a while."
Dou Sprout touched me and said, "Hey, Fengzi, I'm calling you."
"I'm calling you Brother Yu," I looked at Brother Yu.
"It's just you, Xiao Xiang, please stay and help me." Master Ji's voice came from behind.
Dou Sprout and Brother Yu patted me and left.
After just a few minutes, the originally small space felt larger because he and I were the only ones left.
"Master Ji... Master Ji, whatever you ask me to do, I don't know how to do anything."
"Come on, grab me here."
"listen."
Master Ji calmly explained: "The balloon itself is made of rubber and is highly flammable. In addition, there is a layer of oil on the surface. If you press it tightly, I will take some."
"Once it's lit, I'll go out first."
"When I get out, slowly let go of your hand and come out immediately."
"Understood, Xiao Xiang? I've calculated that we have enough time, don't panic."
He called me Xiao Xiangtou, but I was so nervous that I heard him call me Xiaoluotou.
I was so nervous that I swallowed twice and nodded.
"Papa, tapa..."
The lighter may have been dampened. It didn't light up for the first few times, but it took more than ten times to light up.
The flames approached the balloon and slowly ignited.
I pressed against the wall and dared not move. At this time, I could clearly smell the smell of burning rubber.
As soon as the balloon was lit, Master Ji picked up the bag on the ground, turned around and ran out without even looking at me.
"Huh...huh..."
"Calm down, don't panic." I took a deep breath and kept telling myself not to panic.
Ten seconds later, I heard him shout: "Hurry up! Come out!"
I immediately let go, grabbed the small door and crawled out.
"Quick! Quick! Give me your hand!"
After getting through, Master Ji and I ran to the corner, squatted down and held our heads.
moment!
Just hear a bang!
There was a lot of movement and a low sound, as if something was being suppressed and falling apart from the inside.
The smell of sulfur after burning gunpowder made people cough, and a large amount of dust and smoke floated out.
I waved my hands to disperse the smoke, coughed and said, okay, why don’t I go in and take a look.
"Don't wait for five or six minutes. We'll go in when Ranpao Yan'er comes."
"Cough! Cough!"
"It's dead."
"Are you done?"
Half a head suddenly came out from under the horizontal well. Dou Sprout waved his hand and coughed.
"Damn you, you really know how to find a place to hide."
After waiting for a while and seeing no more smoke, we went in to take a look.
I saw a large hole torn open by explosives in the arched wooden wall wrapped in bluestone strips.
The cracks extended around the four small holes made by Master Ji, and splinters of wood were scattered all over the floor.
Tian Sanjiu shook his head when he saw this and said, "If this was ordinary wood, it would have been broken into slag long ago. It really looks like a turtle shell."
"You shouldn't be short of oxygen after a few minutes of walking. Old Ji, you can go over and check the situation."
Master Ji squatted down and looked inside with a flashlight. I also knelt down and looked inside.
It was so dark inside that I couldn't see what was there.
Feeling that the flashlight was not very useful, Master Ji took something from his bag. He said it was a cold light flare, which he bought from a local wild man. He didn't expect to use it so quickly.
He pulled the cold light bomb and threw it in like a grenade.
Just a few seconds later, it was as bright as day, and at that moment, I saw a row of things.
"What's wrong Yunfeng?"
I noticed that my face looked ugly, and Master Ji must have noticed it too. His eyes were wide open, full of horror.
What is it?
It’s rows of dead skulls stacked up!
Just like arranging watermelons!
They were piled densely together to form a wall, and there were so many of them that they were countless!
Looking from the front, it doesn’t matter whether it’s scary or not, but it will give people a huge visual impact.
This is the "Beijing View Wall..."
We were even more shocked when we went in and took a look. The flashlight moved inch by inch and we found that the skulls were covered with clay and neatly placed.
"ah!"
In the darkness, Xiaoxuan behind me suddenly screamed, and I quickly asked what was wrong.
Looking at the place where Xiaoxuan pointed, it turned out that there was a nest of stove horses crawling around.
The stove horse bug uses the skull as a nest, crawls out from the mouth, and crawls down from the eye socket. There are about a dozen in a nest.
This is not an isolated case. After a closer look, we found that many skulls have stove horses living in them. We just didn't crawl out. We can see them if we get closer and shine a flashlight along the skull's eye sockets.
"vomit!"
Xiaoxuan retched and said, "It's so disgusting. How could there be such disgusting things here?"
I said don't look at it, there might be something else living there, it's disgusting.
At this time, Tian Sanjiu suddenly made a sound. He turned around and asked, "Wang Bantou, have you ever seen a wall like this?"
His head looked unhappy, and he thought for a while and said: "Yes, in the early years, I saw it around the bird burial ground in Medogela, but it is slightly different. Each of the Beijing Guanguan Walls there has a separate
The niches, unlike here, are all covered with white mud."
With his head and brows furrowed, he continued to recall: "Xiaohong's father, Chen Xiaohei, died there and was buried alive by several people from their Southern Sect and Changchun Society."
"The little red you are talking about is a mole in the industry, right?" Tian Sanjiu asked.
He nodded his head.
"Hang on, Sister Hong..." I opened my mouth when I heard the sudden discussion about Sister Hong, but stopped talking.
"Don't talk about it for now. It's all in the past. Let's focus on getting through the hurdle in front of us." said the head.
"Come here quickly! I've found something!" Brother Yu suddenly shouted with a flashlight.
"Where? What did you find?"
Brother Yu squatted on the ground and said, "Look, there is a small bluestone tablet here."
At first glance, it’s true.
This piece of bluestone is about twenty centimeters long. Brother Yu wiped the dust with his sleeve and could vaguely see a row of small characters carved by a knife.
It's not a small seal script. I glanced at it and concluded that it was a large seal script. The strokes are relatively simple, with more than a dozen characters. Some of the characters appear to be repetitive.
Because bronzes with inscriptions are valuable, Baotou studied the rubbings for two years when he was young. He studied for a long time and tried to translate them.
I don’t know if the translation is correct or not, but I guess it’s almost the same, it’s probably this passage.
"He who enters dies, and he who opens dies."
"Those who disturb you will die, and those who see you will die."
