Xu Tianchuan claimed to be patrolling by the security team, and then was lured by the three of Lacey to join the gang together, and came to a 'prison guard and steal'.

For the three of Lacey, although their whereabouts were exposed, fortunately, they were able to pull Xu Tianchuan and them into the water together.

He can only divide thirty percent, but Xu Tianchuan and they want to take seventy percent, which makes Lacey have a toothache, but fortunately, Xu Tianchuan agreed to sell his share to himself at a friendly price, which is also a good result, he just broke a little money, but he must still make money.

Now, what is in front of everyone is how to go down.

The high-tech of the three of them is very good, and they also know a little bit about tomb robbing, but they really don't understand this fire hole.

What made Xu Tianchuan feel extremely ridiculous was that at this time, Reis actually took out a cross from his neck, and muttered to the mouth of the thief's cave: "Hallelujah, Mamma Mia......"

Does this Nima really think that their foreign devil's set of things can go all over the world?

Xu Tianchuan feels that his domestic culture has been absurdly insulted!

Even though he silently recited 'Hallelujah' a few times, Reis did not dare to approach the cave easily.

Instead, he looked at Xu Tianchuan and frowned and asked, "Mr. Xu, your ancient tombs already use gas?" ”

It seems that Rey thought there was gas in the burial chamber.

In fact, this is not very different from biogas.

Xu Tianchuan didn't make a sound, and he definitely wouldn't explain this fire cave to Lacey.

The more foreign thieves learn, the greater the threat to domestic tombs, and Xu Tianchuan still understands this truth.

But for the wishful thinking in his heart, he had to take three foreign thieves to the tomb and let them see the 'burial goods' below.

In addition, Xu Tianchuan is also extremely curious about the fire cave below.

What kind of person's tomb is it, since it has done such a clever anti-theft method, but it is buried in such a broken ground?

Regarding this fire hole, it is not that there is no way to crack it, and the way to solve it is very simple.

There is a mantra in "Dragon Shaker" to crack this fire hole: "The fire pit tomb, the fire of burning the body is five zhang, and it is ventilated." ”

In this mantra, the word 'ventilation' is the key!

The meaning is also very simple, that is, the entire burial chamber is ventilated first, and the accumulated biogas in the burial chamber is discharged.

However, the biogas accumulated in the tomb has air pressure, and if it is only a small skylight opened above the tomb, you want to drain all the biogas in the tomb, not to mention a month, but a year, or even more than a year.

You can't wait for such a long time, you can't leave the hole outside for a year and a half, right?

Then you can only dig an extra robbery hole above the tomb to form a principle of air inlet and outlet, and then use a little natural wind? Quickly drain the biogas from the burial chamber.

But isn't that easy? First of all, we must find out the structure of the entire burial chamber, and then we must understand the principle of ventilation? Find out which direction the wind is blowing at the time? In order to be able to form the principle of air inlet and outlet.

If it is said that if one more thief hole is made at random, the natural wind from the outside world will not be able to pour into the tomb in large quantities? Can't get it out, let alone one more? Even if it's ten more, it's useless.

One of the more nouns for this principle? It's called 'pulling the wind'.

"Mr. Xu, in fact, I have a way, why don't we come again tomorrow night, and I will bring the exhaust fan? Pumping all the gas out of the tomb? It should solve this problem. ”

Lacey saw that Xu Tianchuan didn't react for a long time, and then spoke seriously.

"Exhaust fan?"

Jiao San's eyes widened, feeling that his more than 20 years of experience in tomb robbing had been rubbed and ravaged on the ground by the 'high technology' of this group of foreign devils.

The exhaust fan is indeed a solution, but what if Lacey has some bad idea and doesn't come tomorrow?

"Not really? Let me see again. ”

Xu Tianchuan vetoed Lacey's proposal, and then walked to the entrance of the thief cave? I looked down.

The robbery hole with a diameter of more than one meter is vertically downward, and the brick room has also been opened by Will with a jack just now, a forty centimeter long? It has a rectangular skylight about 20 centimeters wide.

As soon as he stood at the entrance of the thief cave, Xu Tianchuan felt a cold breath rushing towards him? This is the methane gas that erupts from the burial chamber? Cold with a peculiar rancid smell? Biogas itself is produced by the decay of some organic matter, and it is not known what kind of organic matter it is.

Because the methane erupts from the burial chamber and is diluted by the air on the ground, it has no ignition point.

Xu Tianchuan didn't use lights, and with his night vision eyes alone, he could clearly see some parts of the tomb below through the skylight above the tomb.

It's a coffin!

Xu Tianchuan stood at the entrance of the thief cave and looked down, and saw the coffin under the tomb at a glance!

These foreign devils are also so lucky, they really hit the thief hole in the main tomb once, and they are facing the coffin of the main tomb!

I saw that it was a red coffin painted with red paint below!

The ancients generally believed that red represented blood and was regarded as a disaster of blood light! Even in ancient times, there were people who used red coffins to bury ominous people, because red is cinnabar color, which has the effect of suppressing evil spirits.

If it were a tomb from another period, Xu Tianchuan would definitely be surprised when he saw the red coffin below.

But at this time, the expression was indeed very calm.

Because this is a Qing Dynasty tomb.

Throughout the Qing Dynasty, the color usage and attention of coffins have formed a complete system.

For example: young people or soldiers use smoke-colored coffins after death; Ordinary people use yellow log coffins that are not painted; White coffins for those who die young; The emperor used a golden coffin.

As for this red coffin, it was also called the 'happy coffin' in the Qing Dynasty, which was specially used for the elderly over 80 years old, and there was no such thing as the so-called evil nature.

Therefore, from the red coffin below, it can be basically determined that the owner of this tomb is an old man over 80 years old, and he also uses the method of 'happy burial'.

Although the skylight is too small, Xu Tianchuan can't see the whole coffin, but it can be seen from the part that the red coffin is decorated with gold pieces and carved with Xuan patterns, which can prove that the identity of the owner of this tomb is very high, and ordinary people don't dare at all, and they are not qualified to use this.

Xu Tianchuan frowned, quickly flipped through the specifications and burial methods of the tombs of the past dynasties in his mind, and then combined with the current form of the coffin, it didn't take a few minutes to basically guess the pattern of the ancient tomb below in his heart.

This ancient tomb sits in the north and faces south, the underground is more than five meters deep, there is no corridor, there is only a front room and a main room, there may be ear rooms on both sides of the main room, and the total area of the entire ancient tomb is about nearly two hundred square meters!

This is a truly qualified, professional tomb robber who can accurately deduce the basic pattern of the tomb below only through some superficial appearances.

Even a few partial chambers and a few ear chambers can be calculated clearly and clearly.

After calculating the structure of the entire tomb, Xu Tianchuan plucked a few mink hairs from his hat and threw them out to measure the direction of the wind.

Now it's a southeast wind.

The location of the thief cave at the foot of the cave is the northwest corner.

Xu Tianchuan walked about ten steps to the southeast, then drew a mark on the ground, and looked at Reis and pointed his finger: "Use the method you just made to make a robbery hole here." ”

Another thief hole?

Wouldn't it be the same if you hit another hole and the gas will spew out?

Although Reis was full of doubts in his heart, he still followed Xu Tianchuan's intentions, personally got started, and used the same method as just now to lay a 'sullen thunder' in the thief hole made by the Luoyang shovel.

Rumble......

With a muffled sound, the same robbery hole was blown out of the location designated by Xu Tianchuan, and the tomb was also not blown up.

But because of Will's example first, no one dared to go down and use a jack to open the skylight in the tomb, and all eyes were on Xu Tianchuan.

Xu Tianchuan's mind heard the prompt sound of the system.

Just when Lacey was playing the thief hole, Xu Tianchuan received the system task with his mind.

Before going to the tomb, you must receive the system task, otherwise it will be a waste?

After the sound of the system fell, Xu Tianchuan did not grind, directly took a Luoyang shovel, walked towards the newly beaten thief hole, first stood on the edge of the thief hole and looked down.

The robbery hole is three or four meters deep, and you can clearly see the tomb bricks, which are not bluestone bricks, but red bricks fired from rammed earth, which are also very in line with the characteristics of brick tombs in the Qing Dynasty.

The tomb bricks are made of glutinous rice and white lime as a binder, and they look very strong.

But in Xu Tianchuan's eyes, this kind of firmness basically belongs to scum......

Sonor!

Xu Tianchuan grabbed the Luoyang shovel tightly and slammed it down.

&njxpxxs.bsp; I only heard a 'clang' sound from the cave, and with Xu Tianchuan's wrist, a tomb brick fell off directly and fell down.

A hole in a brick was exposed.

The biogas in the tomb erupted directly from this hole, but because Xu Tianchuan was far away, the biogas spewed out of the tomb was instantly volatilized and diluted by the air on the ground.

With the blessing of the power of the green dragon's bloodline, opening the skylight to this kind of tomb is simply a child's pee and mud - pediatrics!

But Xu Tianchuan's skill directly stunned the three foreign devils, Reis, Chen Anna and Will.

Especially Will, who was burned by the fire, he had been tossing for a long time just now, even with a jack, he gritted his teeth and pressed down hard before opening the skylight.

And Xu Tianchuan actually only needs a shovel!

Isn't it a tomb?

Under the surprised gaze of the three foreign devils, Xu Tianchuan easily used the Luoyang shovel to expand the robbery hole above the tomb.

With the expansion of the tomb robbery hole, Xu Tianchuan could clearly feel that the southeast wind was pouring down against the ground.

No!

To be precise, it should be that the tomb 'sucks' the southeast wind into it, and at the same time passes out from the northwest direction of the thief hole, forming a phenomenon of 'pulling the wind'.

And the effect of this 'pulling the wind' is much better than Xu Tianchuan imagined.

You can even hear the sound.

After the southeast wind is 'sucked' in, it comes out of the northwest thief hole and whines...... sounds.

The voice was very eerie, and it felt like a demon was roaring in the tomb.

The three foreign devils hadn't figured out what the principle was, so listening to the sound of 'pulling the wind', they suddenly subconsciously took a few steps back with nervous faces.

Lacey still clutched the cross in his hand, muttering 'Mamma Mia'.

"Monks from outside are good at chanting? That's just ......."

Xu Tianchuan glanced at the three foreign devils with disdain, then took out another candle, lit the candle, and threw it into the thief hole in the northwest direction casually.

Rumble......

When the burning candle was thrown down, blue flames erupted from the thief hole in an instant, three or four meters high, like a flamethrower, and it continued to erupt outward with ventilation. zyxta.

The blue flames reflected all around a bright blue, baking everyone's faces hot, and the scene was particularly spectacular.

This is to get all the biogas out of the burial chamber faster and cleaner.

Because the biogas has air pressure, coupled with ventilation on both sides, the flame erupts so high, like an angry volcano.

It is also because of the ventilation on both sides, so there is no need to worry about the explosion of biogas.

The flames also did not burn the burial goods in the tomb, because the flames were burned on top of the tomb.

This spectacular phenomenon lasted about ten minutes.

The blue flames erupting from the cavern suddenly vanished, and the bright blue reflected around them returned to normal.

The disappearance of the flame means that the methane in the burial chamber has been cleaned.

In order to confirm, Xu Tianchuan threw a lit candle down again.

This time, there was no more blue flames, indicating that the methane in the tomb was indeed gone, and the fire cave was no longer on fire.

"Even buy karma, Mr. Xu, your method is too powerful!"

Reis saw that the candle that Xu Tianchuan threw down for the second time did not ignite the flame, and he had roughly seen the ventilation principle, and used the ventilation on both sides to quickly clear the 'gas' in the tomb, which was much better than his own exhaust fan.

So Lacey's sense of admiration for Xu Tianchuan almost hit his knees.

And Jiao San next to him always maintained a faint smile on his face, if Xu Tianchuan didn't have this ability, could he follow him willingly?

"No matter how much nonsense it is, it's dawn! Let's go! ”

Xu Tianchuan doesn't talk much, and he cherishes words like gold, the purpose is to avoid Lacey stealing art.

Although Reis also understood the principle, it was basically completely useless to him.

Because in order to achieve such an effective ventilation, it is necessary to understand the basic structure of the tomb first, otherwise as I said earlier, even if ten robbery holes are made, there will be no such ventilation effect at all.

"Down!"

Sure that the fire cave was safe, Lacey was eager to try, and his eyes glowed green at the burial objects beneath the burial chamber.

Not only Lacey, but even his assistant Chen Anna also had an expectant expression, feeling like a little girl was about to enter the cave room......
