Before entering the Taoist Holy Land, Liu Cong sorted out the remaining food in the team, and he found that these foods were barely enough for everyone to eat together for four or five days, which made him feel a lot more relieved, and it seemed that more people should be able to enter the Taoist Holy Land.

Because the number of teams excavating the Taoist Holy Land this time is not too large, Liu Cong hopes to let as many team members as possible go in together, after all, there are many people who are easy to do. However, if there is not enough food, you can only leave some more team members to hunt outside.

According to the current food reserves, Liu Cong only left two team members outside the tomb gate, one is to watch the tomb door to prevent any accidents from happening, and the other is to let these two people guide them if they really need to use helicopters to transport supplies.

After the team crossed the tomb gate, everyone spread out to the sides to check the mechanism behind the tomb door. Because the nine stone pillars would rotate on their own before, Zhang Linfu had been worried about the limitation of the time limit of the mechanism that opened the tomb door, in case the tomb door closed automatically, the people who were locked inside could only regard this place as their own tomb.

Most of the large tombs of the Tang Dynasty had their doors open only inwards to reduce damage from the outside, and there were usually some mechanisms attached to the back of the doors.

In addition to opening and closing the tomb door, these mechanisms also have a very important function, that is, they can carry some heavy objects, such as the stone pillars that fill the entire tomb passage. When the tomb door is completely sealed, these mechanisms are activated, and the stone pillars that fill the tomb are hung on them.

In this way, when the tomb door is slowly closed, these stone pillars behind the tomb door will move forward with the tomb door, thus sealing the tomb door completely.

But because this is a Taoist holy place, the back of the tomb gate is empty. Maybe it's because of the wind all night, although there is a smell of dust mixed in the air, but the air behind the tomb door can still make people breathe, but it is very cold here, and the non-stop cold wind makes everyone tighten their collars.

There are indeed some similar things on both sides of the tomb door, some huge gears that are perfectly combined with the corners of the tomb door, and it looks like they should be hewn into one piece with the tomb door. From the joints between these gears and the wall, you can faintly see some thick iron chains inside, which are supposed to pull the mechanism of the tomb door open.

What Chen Ziyang and the three of them were most worried about was that the two tomb doors would close by themselves, after all, when they were in the Bohai Palace, they had suffered such a loss.

However, because the records of the Tang Tombs in the "Civil Engineering Collection" are particularly detailed, Umbrella Shishuai, who specializes in Gongji, told other people with great certainty that judging from the mechanism behind the tomb doors, these tomb doors should not close on their own.

Now that their worries were settled, everyone turned their attention to the depths of the tomb. At this glance, one word appeared in everyone's mind at the same time, and that was shabby.

The tattered tomb road formed a strong contrast with the tall and majestic tomb door, and the empty tomb road was not too shocking, and the most shocking thing for the people in the team was the style of this tomb road.

The tomb of the Tang Dynasty imperial tomb is roughly divided into three specifications, the first specification is to dig out the tomb in the mountain, and then use carved stone bricks to reinforce the tomb around the tomb, and at the same time use molten iron poured into the brick joints, such a tomb road is the most solid and gorgeous.

The slightly worse tomb is directly reinforced with stone bricks, although the gaps in the stone bricks will not be filled with molten iron, but the stone bricks are stacked on top of each other when stacked, so the sturdiness of the tomb is also okay.

The lowest-grade tomb road is not reinforced with stone bricks, but directly polished on the side wall of the excavated tomb road, and the tomb road is repaired very smoothly, and then some patterns or patterns are carved on the top of the smoothed rock, so that the sturdiness of the tomb road is poor.

However, although the tomb road in front of everyone is very wide and very long, the two sides of the tomb road are completely uneven stone walls, which have not been polished, and it looks like a rough house.

The marks on it are deep and shallow, very irregular. This is very incompatible with the elaborately carved tomb door, and everyone has a trace of surprise in their hearts.

Looking at the uneven rock wall, Yang Lei whispered his thoughts in Chen Ziyang's ear, it turned out that this kid actually felt that this tomb road was similar to those caves in the shallow water fish dragon, although it was much wider, but this poor and sour atmosphere was exactly the same, it seemed that this should be a poor tomb.

Ignoring Yang Lei's disappointment, Chen Ziyang felt that the rough tomb road confirmed his previous thoughts, it seems that this mausoleum should have been abandoned in the middle of construction, so the rock walls around the tomb road have not been processed more carefully.

With this feeling of disparity, the team walked forward quickly. The structure of this tomb is relatively simple, the surrounding rocks can be seen at a glance, and even some residual excavation traces can be seen, which also reassures everyone a lot, at least there will be no mechanism hidden in this tomb.

The entire tomb path was descending with a large slope, and after following the straight tomb path for a while, everyone saw the stone pillar that had been shown in the sound wave detector.

An unusually large stone pillar stands in the middle of the tomb, and the top and bottom of the stone pillar fit perfectly with the mountain, and it seems that this stone pillar was deliberately left behind when the tomb was excavated.

Several flashlight beams converged on this thick stone pillar, and everyone couldn't understand the meaning of this stone pillar's existence, and it would be redundant to say that this stone pillar was used to support the tomb road.

This tomb road is directly excavated in the mountain, the surrounding rocks are very dense, not even a crack, the tomb road is impossible to collapse, it is very strong, there is no need for this kind of support.

Therefore, everyone agreed that this stone pillar could be some kind of mechanism, or it could be the next test. When everyone came to the stone pillar, they were even more confused, this stone pillar turned out to be a thick stone pillar, and there was no mechanism hidden on it.

The diameter of the stone pillar is about ten meters, which is almost as wide as half a passage. The only difference from the surrounding rock wall is that this stone pillar has been carefully polished, although the surface of the stone pillar is not too carefully polished, there are still some traces of potholes, but it is already clearly different from the rough rock wall around.

After taking a closer look around the thick stone pillar, Chen Ziyang was thoughtful. Then he reached out and touched the stone pillar, and there was a cold feeling coming from the stone pillar.

Then he squatted down and touched the stone ground, although the ground was still cold, but the temperature seemed to be slightly higher than the temperature of this stone pillar.

Chen Ziyang looked at the tomb door with a glimmer of light in the distance, and after roughly calculating the distance between the stone pillar and the tomb door in his heart, he suddenly realized.

"I know, the inside of this stone pillar should be the mountain crack under the non-overflowing spring, in order not to destroy the non-overflowing spring, so the person who built the tomb thought of such a method, and deliberately preserved the mountain crack under the non-overflow spring when digging the tomb road."

Chen Ziyang's words woke everyone up at once, Guo Huaxing and Zhang Linfu nodded at the same time, it seems that Chen Ziyang's guess before was correct, it was precisely because he thought of this method of preserving the non-overflowing spring, so the person who built the mausoleum did the opposite and built the mausoleum directly below the non-overflowing spring.

Since this stone pillar had no effect on everyone, the team continued to move forward, Liu Cong didn't want to waste time on such an indifferent matter, after all, he didn't know how big this tomb was, and it was better to act early if he could grab a second.

There could be no hidden threat around the tomb, so Liu Cong simply saved the time to use the acoustic detector to detect the structure of the tomb, and the team went directly to the depths.

After walking for a distance, the style of the tomb road has changed, although the stone walls around the tomb road are still not very regular at this time, but the difference between the depth and shallow traces has been much smaller, and it seems that it should have been roughly repaired.

As everyone moved forward, the stone walls around the tomb became more and more regular. Looking at these traces, Chen Ziyang estimated that it should be the geological movement that occurred when the construction of the mausoleum had reached the time of refining the tomb road, which led to the abandonment of the mausoleum.

It's a pity that such a large-scale mausoleum is about to be built, and it was abandoned at this time, and it's no wonder that this place will be converted into a Taoist holy place, and no one will let these efforts go down the drain after putting in so much effort.

At this time, everyone had already walked a long way along this passage, Liu Cong roughly calculated the distance he had walked and the angle of the tomb going down, and it was estimated that this tomb road had extended to the bottom of the mountain, and it seemed that it was about to come to an end.

Although there was no danger along the way, the people in the team also suffered a lot of torture, and it was really cold here. I didn't expect this tomb to be so cold, if I had known that this would be the case, I would have taken some more cotton clothes when I set off, and I wouldn't have let everyone suffer this sin.

A team member with an air quality monitor came to Liu Cong's side, whispered a few words in his ear, and showed Liu Cong the data displayed on the monitor. Looking at the strange readings on the LCD screen, Liu Cong frowned.

It stands to reason that as the team progresses, the quality of the air in the tunnels should get worse and worse, and even if there are no toxic substances in the air, the oxygen content should begin to decline. But now air quality monitors show that instead of getting worse, the air quality here seems to be better, with higher levels of oxygen.

Liu Cong estimated that the tomb was probably connected to the outside world, and that it was the geological movement that caused a huge crack in the tomb.

Although this is likely to solve the problem of insufficient oxygen carried by the team, Liu Cong is a little worried, if this is really the case, maybe the things in the mausoleum have already decayed.

After not going far, another relatively small tomb door appeared in everyone's field of vision, but this tomb door was open, and the two doors had opened at a relatively large angle, and there was a pitch black behind it.

The two tomb doors were engraved with the beast faces of two huge tomb beasts, and these two beast faces occupied almost the entire tomb door, and seeing that the tomb road had finally come to an end, Liu Cong became cautious.

The acoustic detector revealed that there was a huge space behind the tomb door, so large that there was no way to return the sound waves emitted by the detector. The cautious Liu Cong sent two members of the team into the tomb gate, while the others waited quietly in place for the result.

Two minutes passed quickly, but the people who stepped into the tomb gate did not respond at all, Liu Cong shouted into the communicator for a long time and did not get an answer, and all the people in the team became nervous at this time.

For the sake of prudence, Liu Cong sent two team members again, but like the previous two team members, these two team members still did not move after entering the tomb gate, and there was no feedback at all.

A sense of fear instantly permeated the team, Liu Cong stood there at a loss, and then he gritted his teeth, ready to go forward to check in person, at this moment, his communicator sounded.

Liu ...... Captain Liu, can you hear me? ”

"I heard, what the hell is going on up ahead, is there any danger? Why don't you hear anything at all? Liu Cong asked eagerly.

"There's no danger, we're just shocked, come and take a look, it's amazing, it's incredible!"

The words of this team member made Liu Cong angry enough, and he didn't have anything practical after talking for a long time.

"What the hell is going on?"

"Here...... There's a city here! ”

"What!" Liu Cong thought that he had misheard, this was obviously a mausoleum, how could it become a city, but he could see from the equally surprised eyes of the people around him that he had not heard it wrong, the team member was talking about a city.

Although the words of this team member made the fear in the hearts of the others disappear, they also aroused their curiosity, and from the words of this team member, everyone could hear that this person was really surprised.

With this curious mentality, Liu Cong crossed the tomb gate, and the others followed one after another.

After Chen Ziyang crossed the tomb gate, he found that the four team members who had entered before were standing there properly, and Liu Cong and the others who had entered before him were all standing there motionless, all of them tilting their heads to look in the direction next to them.

Following everyone's gaze, Chen Ziyang was also stunned, and a huge city stood in front of everyone.
