Chen Ziyang carefully observed the neighborhood by smelling the words. The method of smelling wood does not apply in this area, less than 30 kilometers upstream of the Weizi River is the forest farm of Linhai City, from where a large amount of wood can be transported with great effort by simply using the method of draining, and this is the case now, and even more so in the past, so there is no need to cut down trees nearby to build a tomb here.

Chen Ziyang carefully observed the vicinity according to the method of smelling soil taught by Professor Tujili, and soon saw some clues on a mountain peak in the distance. There are relatively few exposed rocks on the nearby peaks, and it is estimated that most of the stones are buried below the soil layer, and the surface of the mountain is also overgrown with various trees.

At first glance, there is a mountain peak that looks green, but when you look closely, there are very few trees on the peak, most of them are shrubs and weeds, and there are basically no trees that have matured for many years. And the surface of this mountain is significantly more bare than other mountains. This is probably where the mausoleum was built in the past.

Sure enough, there is a tomb here! And looking at the amount of soil, the scale of this tomb is not small, Chen Ziyang verified his idea that there is a tomb by listening to the words.

It's a pity that Chen Ziyang's trick is only a scratch of the surface, otherwise the approximate age of the tomb construction can be deduced from the details of the earth and stone mountain.

It's already afternoon now, and if you don't go back, you'll have to stay overnight in the mountains. Chen Ziyang took out the compass, selected several obvious peaks as landmarks, carefully noted the location of the dragon's lair, and then dragged his tired body and walked in the direction of the Weizi River.

Four hours later, when it was just getting dark, Chen Ziyang found a dirt road and miraculously hitched a motorcycle on the road. The owner of the motorcycle was a villager from Weizihe, who went to the nearby mountains to collect wild medicinal herbs. heard that Chen Ziyang was going to stay in Weizihe, so he enthusiastically picked him up and asked him to go to live in a small hotel opened by his family. Almost every villager in Weizihe has opened a hotel or a restaurant, and he is also very happy to go up the mountain to collect medicine and unexpectedly bring in a guest.

Chen Ziyang sat on the back seat of the motorcycle, smelling the scent of grass, and looked in the direction of the diving fish dragon. Who owns this tomb? When was it built? Who is buried? How did the materials used in such a large amount of work come from? Forget it, I may not be able to get the answer in my life.

Summer goes to winter, and the winter in Big Walnut Town is exceptionally cold this year. What is colder than the weather is Chen Ziyang's heart. A piece of bad news has cast a shadow over the family.

Chen Ziyang's father, Chen Nianzhong, has been retired for a few years and has been idle, but this year the old man and a few people carried water to pour ice at a puddle by the river and opened an ice skating rink. Chen Nianzhong skates there during the day, and then waters the ice rink in the evening, so that he can exercise his body, and he will not panic when he has nothing to do.

On this day, Chen Nianzhong fell while skating, and it was also an inch, Chen Nianzhong skated every day, and it was okay to fall every day, but this time he broke two ribs. Originally, this is not a problem, the elderly have loose bones, which is also normal, just take care of it. However, when Chen Nianzhong was doing a chest X-ray, the doctor found that there was a shadow of a suspected tumor in his mediastinum, and the doctor suspected that it was lung cancer.

"Doctor, what is the mediastinum ......" Chen Nianzhong's first thought when he learned about this was to ask where the mediastinum was that he didn't know, instead of asking what to do with lung cancer, the old man's heart was big enough.

Chen Nianzhong has worked as an eye worker in the big walnut iron mine all his life. The so-called eye worker, the accurate name should be rock worker, that is, the rock drill operator who makes a blast hole in the rock underground. The ore layer of the large walnut iron ore is not like the surface ore of the main iron ore producing area of Australia, and the open pit iron ore is cut open for a few meters of soil. The ore layers here are deep iron ores, and some of the deepest places are hundreds of meters below the surface.

Sunlight never shines in the mine, which is a few hundred meters deep, so the temperature inside the mine is below zero all year round. Workers working underground wear padded jackets and pants all year round. No matter how hot it was outside, the cold wind blowing from the mouth of the mine could make people standing twenty meters away from the mouth of the mine shiver. Chen Nianzhong's job is to drill holes in the surface of the mine in the depths of this icy mine.

The first step of mining starts from the rock masonry, the rock worker's tool is a rock drill, the shape of the rock drill is somewhat like a machine gun on the bracket, the long barrel is called the drill, the piston of the rock drill constantly hits the drill tail, and continuously sprays pressure water from the center hole of the drill, and discharges the rock slag out of the hole, and it will form a circular borehole of a certain depth on the rock. One of the functions of pressurized water is to flush out the residue of the rock, and the other is to absorb dust and prevent dust from causing harm to the human body.

After the explosive hole is laid, there will be a special blaster to put the explosives connected to the detonator and put the waterproof sleeve into the blast hole, and then detonate it in a safe place, after the explosion, there will be workers to load the blasted rock or iron ore into the ore truck and transport it out of the mine.

The shape, size and material of a waterproof case and a condom are almost identical, except that the waterproof case does not have the protrusion at the front end of the condom, and the front end of the waterproof case is a standard semi-circular type. Moreover, the surface of the waterproof sleeve is not lubricating oil, but there is a layer of talcum powder on the inner surface, which also plays a role in lubrication, which is used to prevent the waterproof sleeve from being damaged when the explosives are put in, so that it cannot be detonated by moisture.

Big Walnut Iron Mine is like Chen Ziyang, a batch of post-80s generations, all of whom have played with waterproof covers as balloons since childhood, and everyone has a few boxes. However, sometimes the waterproof cover at home is gone, and Chen Ziyang will also find something similar to the waterproof cover in the drawer at home, which is also very fun to blow, and there is a small trick in front of it, and there are many floating points on it.

But the annoying thing is that as soon as this "balloon" blows, it will get his mouth full of oil, and every time he plays with this thing and is seen by his parents, he will be beaten......

Later, with the improvement of explosives, the more powerful waterproof explosives replaced the original soil explosives, and the waterproof sleeve withdrew from the historical stage, but it became the eternal memory of Chen Ziyang's generation of children in the mining area. Which kid hasn't been beaten for it......
