The tomb road extends in all directions, and Professor Lin walked towards the main road according to the underground palace map roughly planned on the ground before. Pen, fun, and www.biquge.info

Su Yun looked at the slightly lower forks on both sides, because of the reason for walking down, after entering, there was still a faint humidity in the tomb.

I took a picture of it and it was "Mikawa soil" that I used. The tomb wrapped in Sanhe soil is not only a model of anti-theft tombs, but also strong and moisture-proof. Su Yun was slightly surprised in his heart, this is not the moisture that seeped in from the heavy rain and soil layer outside, there is moisture on the fork in the road, which means that there is still a road ahead, this main tomb road must be a wrong judgment, and going forward can only be a dead end.

Su Yun called out to Professor Lin and the others: "Professor, there must be sand and gravel blocking the road ahead, let's go to these two sides."

Professor Lin, Wang Fan and others didn't believe it: "How is it possible, you see that the main road is wide and more than enough, how can it be sealed and go forward."

"Professor, you see that the top is a means of triple soil, there is no trace of moisture on this main tomb road, and the front is definitely not filled with soil, there should be sand and gravel piled up."

Professor Lin and the others were surprised to hear Su Yun's words.

And felt impossible.

Because the anti-theft means of Sanhetu only began to appear in the Song Dynasty.

Wang Fan was a little despised for Su Yun's misjudgment in knowledge, but he still explained in detail: "You must not know the function and origin of Sanhe soil, let alone the age when it appeared, so you will say so, because you said that this is a Han tomb from the beginning."

In her tone, she seemed to feel dissatisfied and disappointed that Su Yun was worse than her expectations, as if she was disappointed by the big guy.

"Sanhe soil is hydrated lime, clay and sand mixed together, filled with mud and gravel, poured back and forth on the top and outer layers of the tomb, tomb robbers can only open up seven or eight layers of it is very powerful, that is, modern stainless steel can not drill through, can only use large machinery to drill through, anti-theft means belong to the first level. Such tombs include the tomb of Zhang Shicheng's mother in the Song Dynasty, and the tomb of King Bei'an at the end of the Yuan Dynasty, which is a Han tomb, although the identity of the tomb owner has not been determined, but it is impossible to use Sanhe soil to cap it, so you speculate that there is no moisture in front, and it is possible that the sand and soil seal the road is also wrong."

Su Yun thought about Sanhe soil, and then she remembered, she judged at first that Ling Qi and the others might have entered the thief hole, but now, with such a solid Sanhe soil capped, how could they get in?

Don't think about it at the main entrance, the tomb robbers have robbed the hole, and the main gate is the official.

"There's no moisture in the tomb, unless it's a road, what else can explain it?"

It is not said that the capping is not a triple soil, but it is a very solid sand and gravel soil layer, and there is no moisture on the road, and there is no circulation.

Professor Lin also looked at the top layer of the tomb above and took a photo: "It looks smooth and can be seen, it is really a great workmanship, and it is very likely that there is a moisture-proof soil layer or something in it."

They don't believe that it is the top of the tomb that does not absorb moisture and only blocks moisture, so they cannot say that there is sand and gravel blocking the road in front of them.

And go on.

Tang Yiju said: "Let's go this way, we won't be with them."

Because of Su Yun's previous opinions on the two dead people and the statement of entering this tomb, as well as the things in the village, Tang Yiju trusted Su Yun very much, although she looked down on Su Yun before.

But now that it's surrounded by dark graves, it's natural to be nervous and want to find someone who is more familiar with the environment.

Obviously, Su Yun's performance made her feel reassuring to follow Su Yun.

And she didn't think it was necessary to take a dead end to delay time.

All she wanted now was to get her two children back and get out of here.

Su Yun looked at Professor Lin and the others who were walking forward.

After thinking about it, I followed along.

"They will be in danger".

The sound of footsteps is heard in the tomb tunnel, which has not been activated for thousands of years, and it feels like many people walking.

Su Yun looked at the people who came in front and back, in addition to the two children who were held by six adults on their side, there were also seven people on the archaeological team's side, although there were thirteen people in the footsteps of the group, but listening to this sound was still a little too much.

There is a feeling that there are so many more than that.

Su Yun approached Tang Yidong and pulled him and whispered, "Do you think that the sound of walking here seems to be more than just us."

"There is a ...... What does it feel like to be in a group? ”

Tang Yidong noticed it just now.

didn't say it, I just didn't want Su Yun to be afraid.

In fact, he, Tang Chen and Tang Mao could all hear that the footsteps here, except for the archaeological team and Su Yun and a few people walking, he and Tang Chen were soldiers and the sound of walking was very consistent.

In addition to these two waves, there is a third wave of voices that are very consistent.

Tang Yidong held her little cold hand in the palm of his hand.

"yes, I heard you."

Su Yun took a flashlight and shone around, but there was nothing.

Not only the tomb road, but also the tomb roof and the wall tiles on both sides, are very polished and smooth, except for the stairs that go down a little strange dirty dust, the rest of the place is very clean, not like the feeling in the ancient tomb.

I walked forward for a while, but I still didn't see the end, and I didn't have the feeling that the sand and gravel were blocking the way as Su Yun said.

There are many forks in the tomb that are misleading, if the tomb robbers come in, they may get lost and then suffocate in this ancient tomb.

So Su Yun has been paying attention to the surroundings, but the walls and tomb roads are all consistent gray stone brick roads, and there is nothing strange about it.

I walked for a while and didn't reach the end, but I didn't come across what Su Yun said about sand and gravel filling the road.

A member of the archaeological team was a little disdainful of Su Yun and his party walking behind.

felt that Su Yun and they were dragging their feet.

"It doesn't matter if you don't understand, but please don't talk nonsense to show you, let alone say something to mislead our itinerary and cause psychological tension in the accompanying team members."

The person who said this was a researcher named Xiao Zhou.

Su Yun doesn't care about anything, and generally people she disdains don't even disdain to debate.

Because of those words, people who lack so much tendon in their brains can't figure it out, unless they let him see it for themselves.

Tang Yiju is a straight person: "Who are you talking about, who is talking nonsense, if it weren't for our Su Yun, I'm afraid there is still one of you in the team who has become a hedgehog, and the one who died may be you."

Xiao Zhou didn't expect this yin and yang weird irony to be told back directly.

The angry forgot to move forward.

Professor Lin shouted, "Where are you now, you are still arguing here!" ”

For a moment no one was talking, but the footsteps were loud again.

The light of the flashlight flickered left and right in the tomb, and the colliding white light could illuminate the steps downward.

The differences in the stairs are subtle, but the stairs that looked a little gray on them before, although I don't know what happened, but you can see that they are not clean, and it seems that there is always something on them.

The stairs swept by the glimmer of the flashlight were smooth and clean, almost shining with a cyan oily sheen.

Everyone is moving forward, where will pay attention to this detail.

Su Yun only came and shouted, "Wait a minute".

I saw that the researcher who was walking in the front didn't even make a sound, and the stone slab he stepped on immediately turned up and down like a moving board, and the researcher fell down, and then he heard a "click" sound, as if he had touched the ingenuity of the mechanism.

I saw a rumbling sound in front of me, and at the end of the flashlight just now, a huge stone door rose.

"Oops, it's a diamond."

"Run back!"

Diamond is a deep hidden anti-theft stone door in the cemetery, behind the diamond is generally flooded with yellow sand like the sea, craftsmen in the construction of the grave behind the diamond are every time they dig out a car of soil, then fill in a car of sand into the tomb, so that the tomb road filled with sand is not like a glued thing composed of soil, the sand is loose, digging will also gather and disperse, can not rob the hole, not only effectively prevent the tomb robbers from robbing the hole, there is also the sand moisture-proof, more anti-corrosion, so the diamond door has been opened every thousand years, and it is still running normally.

Su Yun and the others encountered the sand behind the diamond door head-on, which was more dangerous than digging a thief hole, because digging a thief hole was at most a change of place.

And they meet it head-on, triggering the diamond, and this sand overflows to bury people.

After Su Yun finished shouting, he pulled Tang Yidong and ran forward.

Originally, the people in front and now in the back also reacted, originally striving to go as far forward as possible, but now they are in a hurry to retreat in the direction of the back.

It's just that the sand is much faster than them, and it rushes loosely against the stone wall and the top of the tomb.

Now Su Yun knew why the stone walls and tomb roofs here were so smooth, apparently to increase the flow speed of sand.

As Professor Lin ran, he couldn't help but exclaim: "How did so much sand come in!" ”

"Wait for me, save me!"

A bespectacled researcher tripped over the ground in fright, as the stairs were stone, his knees were bleeding, and he was screaming for help with his arms outstretched.

The person next to him took his hand, but because of this, he was one step slower, and he was immediately drowned in the sand mountain.

When I came in this tomb just now, because I was exploring forward, I didn't think it was very long, but now I feel that it is very long when I run for my life.

The group ran forward lifelessly, Su Yun ran a little panting, not to mention the people from the archaeological team around him.

They are all people who are engaged in research work, and their physical strength is naturally not good.

Tang Yiju and the others are fine.

Su Yun felt that his legs were a little weak, so he was picked up directly, and then ran forward.

Straight out of the main cemetery road, which was originally misunderstood, the amount of sand that flooded people was stopped.

Looking at the graveyard filled with sand below, Professor Lin and the others were out of breath, feeling that both ears were spewing smoke and tired.

Professor Lin gasped and looked around, and three of his companions were drowned behind the sand mountain.

Now there are only two students left, Wang Fan and Zhang Wenjing, and one colleague is Xiao Zhou.

The one who sarcastically mocked Su Yun just now didn't believe that there was sand and gravel blocking the road, but he survived.

Tang Yiju crossed her waist and panted, and said sarcastically to Xiao Zhou: "Didn't you believe it just now, I see that you ran quite fast this time, your colleague fell next to you just now, why don't you know to reach out and pull?" ”

Xiao Zhou stiffened his neck and refuted: "It's not that I don't save him, it's that I can't save him, Lao Zhao was buried just to save people."

He choked up as he spoke.

Tang Yidong shouted Tang Yiju, after all, three people died at a time.

Tang Yiju is a soldier, and his nerves are naturally much stronger than ordinary people.

Snorted coldly at Xiao Zhou, who was crying, and didn't say anything.

Xiao Zhou cried and cried, and suddenly ran out.

"I'm going out, this tomb is weird, I'm leaving!"

He ran towards the entrance to the tomb where he had entered.

Professor Lin saw that Zhang Wenjing still wanted to call him, so he grabbed Zhang Wenjing: "Forget it, this place is not far from the exit, and he won't have an accident, so let him out."

Professor Lin was completely convinced of Su Yun this time and asked her where to go.

In fact, when he was running just now, Su Yun noticed that the chaotic sound he heard before was still far louder than when they ran together.

asked Tang Yidong quietly.

"I feel like 'they' are still following us."

Tang Yidong didn't speak, just nodded slightly.

This is a place located at a three-way junction, and the one that went in just now has been gambled by the yellow sand, and now there are two forks left.

Su Yun looked left and right, it was dark on both sides, and the distance of the flashlight's light was only half a meter away, where should I go?

Su Yun first walked to the left with a flashlight, about ten steps away, Tang Yidong called her, and Su Yun had no choice but to return.

Then she raised the flashlight and walked almost ten steps away towards the side of the fork in the road, at this time, the flashlights of Tang Yidong and the others could no longer shine on her.

"Enough, Su Yun, come back."

Tang Yidong knew that she was trying to walk left and right by herself, to see if the strange and strange steps were following her, to guess whether these steps were following her alone or a group of them.

So when Tang Yidong and the others looked at Su Yun strangely, Tang Yidong didn't follow her, and now when he saw that she had left the TV line, he called her back.

I didn't hear the echo, thinking that Su Yun was finding something on the wall like just now, after all, this place is so close, and Su Yun is the kind of person who will stop when he sees the details.

Tang Yidong shouted again.

"Su Yun".

Still didn't hear an echo.

Tang Yidong suddenly strode forward a few steps.

There was nothing but the dark tomb road, where the walls and the masonry on the ground were still smooth, but it looked like no one had passed by.

Tang Yidong's face turned dark all of a sudden.

Because he noticed that after Su Yun shouted out just now because he was nervous, after coming over here, their group almost came over with a hula, but there was no strange sound from the group that followed them just now.

The voice was gone.

Su Yun also disappeared.

Their target is Su Yun.

"What's going on! How could Su Yun be gone! ”

Tang Yiju searched left and right on the wall, and her voice was full of surprise and surprise.

Su Yun's disappearance is simply unimaginable and unpredictable.

"yes, how did it disappear."

Professor Lin and his students were also shocked.

Tang Yidong pulled Zhang Wenjing over from the crowd, pinched him by the neck and pressed him against the wall.

"Say, where did your people get her?"

Everyone else looked at Tang Yidong in shock.

Professor Lin was also a little flustered and inexplicable: "You calm down, he is just an ordinary student, how can he know, and your girl is missing, how can he have anything to do with him when he is so far away?" ”
