Zhou Xiaolong shook his head and said to Professor Cui: "I can't see through whether there is a treasure or not, but there is indeed something yin and evil hidden underground, just now I opened the yin and yang eyes, this area is surrounded by a strong yin qi, it is indeed a fierce place!" ”

Professor Cui asked again: "Using the theory of Feng Shui and the compass in your hand, can you find out the specific direction?!" ”

Zhou Xiaolong replied with great certainty: "Actually, I have already found that point, but I deliberately delayed time and thought about how we could escape?" ”

Professor Choi was an old pedant, and when he heard about the discovery underground, he almost forgot that he was still in danger.

"Ah, where?!" Professor Cui hurriedly asked.

"It should be under our feet!" Zhou Xiaolong pointed to his feet and said to Professor Cui, who was staring at him in a daze.

The so-called feng shui can be simply summarized as: the place where the wind is hidden, the place where the water is obtained.

As I said before, when Zhou Xiaolong first came here, he had already seen that the three rivers had divided a triangular area.

The feng shui pattern here is very suitable for burying women, and it will definitely bless the descendants for generations, but if there are men buried in the treasure land of feng shui here, I am afraid it is not a good sign.

Zhou Xiaolong didn't have the time and interest to explain anything to Professor Cui, but lowered his voice and said to Professor Cui: "If everything goes well, there is really such a gas valve underground, and when I locate it, those people enter below, we have to take advantage of their unpreparedness and escape from the chaos, Professor Cui, do you understand what I mean?" ”

"Understood, understood." Professor Cui nodded heavily.

So, Zhou Xiaolong observed around this area for a while, and then waved at the middle-aged man and pointed to his feet.

"Right here!" Zhou Xiaolong said loudly.

The middle-aged man was anxious, and immediately ordered his subordinates to take out the tools for making holes.

It was a rectangular box, and when it was opened, there was a cowhide sleeve inside, about sixty or seventy centimeters long, which looked a little precipitated.

Lao Hei stretched out his hand to open the holster, Zhou Xiaolong looked down, and it turned out that there was a hollow rebar pipe about half a meter long inside.

Lao Hei took out the steel pipe, there is not only one steel pipe in it, but layers of each other, a bit like a retractable police throwing stick, which can be connected and extended.

Lao Hei pulled out three sections of steel pipes, twisted them into each other, and took out a shovel head from the holster and installed it at one end of the steel pipe.

Both Professor Cui and Zhou Xiaolong know that this is the shovel head of the Luoyang shovel, and these Luoyang shovels can be disassembled for easy carrying.

Lao Hei did this very quickly, the steel pipe was aimed at the thread on the shovel head and rotated and tightened, compared to it, there was a length of about two meters, compared with before, this portable telescopic Luoyang shovel has been very advanced.

In the early years, Luoyang shovels were all used with wooden handles, which were generally good ash poles, because the ash tree was extremely tough, and it could be easily bent without breaking.

Don't look at this Luoyang shovel is like a shovel, it is very simple, in fact, it is very troublesome to make, and it needs to go through nearly 20 processes such as billet making, calcination, heat treatment, forming, and sharpening.

The most important thing is that the arc created when forming needs to be carefully and repeatedly beaten, and if you are not careful, the shovel will not be able to carry the soil, which will be wasted, therefore, a good Luoyang shovel can only be made by hand.

It seems that these thieves still continue the traditional Luoyang shovel positioning method.

In the position designated by Zhou Xiaolong, Lao Hei made a slender deep hole with a diameter of about eight centimeters, and then, the middle-aged man took out an oilcloth bag, opened the bag, and the smell of gunpowder immediately came out of it.

The middle-aged man seemed to be an expert in explosives, and he used his hands to clump the gunpowder powder into balls the size of duck eggs, and threw them into the deep hole of the Luoyang shovel, about two dozen of them, as if he felt that it was almost enough.

Then, Lao Hei inserted a lead wire into the hole.

After lighting the fuse, Zhou Xiaolong was very curious, seeing that it was about to explode, but those people were not very nervous, as if they had set off a small firecracker, they only withdrew a distance of one or two steps behind, and they didn't even block their ears.

What Zhou Xiaolong didn't expect was that when it was detonated, he only heard a muffled sound of "poof", and with the muffled sound, the ground under his feet trembled slightly, and that was it.

Is this explosives?!

Professor Cui and Zhou Xiaolong were very surprised, a little inexplicable, this was obviously a special explosive for tomb robbery.

Looking down, in the blink of an eye, a deep hole with a diameter similar to the size of a manhole cover had been blown out, just enough to drill into a person.

Professor Cui said to himself: "This kind of professional explosives probably use the principle of high temperature and compressed air, no wonder many tomb robbery sites are very deep, but there is no mound of soil on the surface, it turns out that this explosive is used, it is really convenient and fast to do this!" ”

The entrance to the cave has been robbed, without a spade or shovel, indeed, this is much more convenient and faster than the ancients to rob the tomb.

The middle-aged man first found the skinniest little brother and let him be the first to drill down and take the lead.

After the little thin man went down, it only took about ten minutes to climb up from below, and said to the middle-aged man: "Boss, there is indeed a door below, the door is welded by steel plates, and there is a circular rotating handle in the center. ”

The middle-aged man walked up to Zhou Xiaolong, patted him on the shoulder and said, "Great, little brother, you really have two hits, since that's the case, let's go down and have a look together, right?" ”

The middle-aged man's request caught Zhou Xiaolong a little off guard, he thought that those thieves went down to steal the treasure, and they shouldn't have to let Professor Cui and himself follow him to get in the way.

However, this middle-aged man was too cautious, or he felt that Zhou Xiaolong did have two brushes, and he had to pull him down.

So far, Zhou Xiaolong is not easy to refuse.

In this way, under the arrangement of the middle-aged man, including Professor Cui, one by one they drilled into the robbery hole that resembled the wellhead, fortunately, the distance below was not too high, because this was not an ancient tomb, but an underground warehouse built.

Not long after going down, the middle-aged man took the lead in turning on the flashlight, and Zhou Xiaolong saw from a distance that a large high-pressure gas valve appeared in front of him.

The door was heavy, the steel plate was probably made of stainless steel, and in the center, there was a metal disc with a diameter of 30 centimeters.

Maybe turn the disc and the metal door will open.

Professor Cui said that he also did not know how this type of valve worked, and could only guess.

This kind of door probably uses high pressure to expel the gas inside, and the door will close very tightly.

After the door is closed, it is both moisture-proof and burglar-proof, and similar devices are widely used in many foreign vaults or museums.

"Hey, hey, hey...... Let's see, what's behind this door?! ”

The middle-aged man's eyes widened, he spat twice in the palm of his hand, and began to rub his hands.
