After Fat Wei commanded everyone to dig down for another three or four meters, he saw that the soil layer on the ground had turned burnt yellow, like a layer of gold, and Fat Wei immediately shouted to stop, no longer letting others do it, but picked up the sapper shovel himself, like embroidery, and cut away the golden soil little by little.

After a while, I saw that under the golden layer of soil, a piece of glass-like roof was revealed, and the roof looked very transparent and brilliant, like a diamond inlay.

"Sure enough, it's a thing", Fat Wei stood up with a sweaty face and said, "I thought of it, if this nine-tailed sky fox's cemetery was established during the Warring States period, then there must be a thing, this is a legend of the Warring States Period, called Tianbao Dragon Fire Glass Top." ”

The parrot looked at the glazed roof protruding from the ground, it was very rare, "Fat Viagra, what is the Tianbao Dragon Fire Glazed Roof!" ”。

Fat Wei wiped the sweat on his face, and said with a senior insider's look, "This Tianbao Dragon Fire Glass Top, also known as Fire Glass, is a unique anti-theft mechanism in the Warring States Period. There are many people who think that this thing was invented in the Northern Song Dynasty, but in fact, it is all nonsense, this day Baolong fire glazed top only appeared in the Warring States Period, and it has been lost since then, and has been imitated by descendants many times, but it has never been imitated successfully.

Don't underestimate the Warring States Period, in fact, the Warring States Period was an era of many craftsmen, and many legendary cow breakers with superb craftsmanship appeared in that era. Their technology, beyond the limitations of that era, modern technology is beyond the reach of dust, although it has now been lost, but when we fight, we can often see the shadow of these craftsmen of the Warring States Period.

During the Warring States period, there was a very famous builder named Ziqing, this Ziqing was very good, and the mechanism he designed was known as a ghostly workmanship.

During the Warring States Period, most of the mausoleums of princes and nobles were designed and built by him, and it is said that this Ziqing never hired craftsmen or apprentices in order to prevent his skills from being passed on, and he gave birth to 88 sons, and all the mausoleums were built by him and his sons.

And this Tianbao dragon fire glazed top is his masterpiece, the structure of this glazed roof is very cumbersome, the tomb is hollow, the ceiling is laid with a very thin layer of glazed tiles, there are bags of Western Regions dragon oil on the tile, and then there is a layer of glazed tiles on the top, and then it is the sealing mound, as long as the external force enters, this top will be broken as soon as it touches, and the Western Regions dragon oil will be on fire when it sees the air, and the bones and burial goods in the tomb will be burned, and the tomb robbers will be burned to death in it and the tomb owner will be buried.

Since ancient times, this day the treasure fire dragon glazed how many inverted bucket masters were burned, so that the tomb robbers were frightened, and finally there was a saying that they would abandon the fight to save their lives when they saw the fire glaze.

Later, this Ziqing and his 88 sons, I don't know why they suddenly disappeared, there is a legend that they were invited by Heaven to be immortals because of their superb skills, so this kind of mechanism was lost after the Warring States period, and it is difficult to see it now, it seems that although this place is a tomb of gods, but at that time the tomb was still a person! ”

"Okay, you, Fat Wei, you have two hands!" , Chen Zhiqian smiled and said to Fat Wei, "It seems that you don't usually brag in vain, it's very useful at critical moments, the question is, how do we get into this Tianbao Dragon Fire Glass Top?" ”

Fat Wei grinned at this time, "Hehe, after several generations of hard research in our inverted fighting world, now this kind of Tianbao Dragon Fire Glazed Top can be broken, to tell you, the biggest weakness of this mechanism is that it can't be too big, I dig from the side, bypass the glazed roof, and the glazed tiles on the top will not break, but be careful when digging, don't detonate the glazed tiles." ”

"Okay, let's do it now!". Chen Zhi didn't let others do it first, and he and Fat Wei had a shovel for each person, first circled a range, and began to dig up, and after digging a rough location, he changed to the next group.

Several people were in a hurry, forgetting their exhaustion, and soon dug a large pit six or seven meters deep on the side of the glazed tiles.

And in the big pit, I encountered a layer of hard soil, which was as solid as a rock, and only a white mark appeared when the sapper shovel knocked on it, and it could not be dug at all.

The parrot scolded at this time: "M's, why is there cement here?" We didn't bring explosives with us, so how are we going to dig down? ”

"Phew! Where did the cement come from in the Warring States Period", Fat Wei said with a smile on the parrot, "This is called the rammed earth layer, which is the most common curtain wall in the ancient tomb, this is actually a mixed soil, which is mixed with the secret recipe of the palace at that time, which is mixed with some glutinous rice juice, as well as boy urine or something, which is stronger than his mother's modern concrete." ”

After speaking, Fat Wei rummaged through the treasure bag, took out a small bottle, opened the bottle cap, poured the water in the small bottle on the rammed earth layer little by little, and said: "This is the old vinegar, break this rammed earth layer, and wait for the old vinegar to volatilize, this tomb wall will be corroded almost, you don't look at the vinegar is too corrosive, but it has a miraculous effect on this kind of rammed earth prepared with a secret recipe, which is called a thing and a thing, and then we dig it will be similar to digging tofu."

Everyone waited for the old vinegar to evaporate and then proceeded according to the law, and sure enough, the soil layer was as soft as a tofu block, and after a few cuts with a sapper shovel, a big hole was immediately broken in the tomb wall. Chen Zhi took a look at it with a searchlight and found that the space inside was really not small, but it was dark underneath that he couldn't see how deep it was.

The parrot was overjoyed when he saw the hole open, rolled up his sleeves and wanted to put the rope and jump in, but Fat Wei grabbed him: "You don't want to die, go to the side, wait for me to measure the air quality." ”

The madman specially reminded them that there are drug test strips from various regions in the treasure bag, and when they encounter a new environment, they should use the test strips to ensure safety.

Fat Wei took out a test paper at this time, and pulled out a bundle of transparent thread from his bosom, the line body is very thin and looks like an LED light strip, Fat Wei folded the transparent line a few times, this line immediately started to light up the whole body, Fat Wei glued the test paper at the end of the transparent thread, and went into the tomb below.

I saw that the darkness below was illuminated, and I could clearly see the floor of the tomb, which was only more than two meters high from above. After about two minutes, Fat Wei pulled up the transparent line little by little, and saw that the label on the test strip was red, which meant that the air contained harmful elements.

In fact, it is very normal to think about it, the tomb below has been closed underground for more than a thousand years, and the air inside is not circulating, even if there is no corpse poison, the air that has not flowed for more than a thousand years contains harmful elements, which is a normal thing.

Fortunately, the parrot didn't jump in recklessly just now, otherwise it would have suffered a big loss.

So Fat Wei told everyone that they needed to wait a little longer on the top, so that the bottom could be ventilated, and the new air could be poured into the poisonous gas.

So everyone sat on the spot and rested for a while, and today they did a lot of work, everyone was very tired, Chen Zhi didn't let everyone light the fire and smoke, after all, that day the Baolong Fire Glass Top was too close, and it was too old to resist the provocation of the open flame, and the slightest deviation would burn everyone to death in it.

After resting for a while, the air coming out of the cave was no longer as choking as before, and Fat Wei still used the old method to use a thin wire to smooth the test paper into the hole, and the test paper taken out this time was already green, and it seemed that there was no problem.
