Last time, it was said that Shen Yifan agreed to Professor Wang's invitation to go to Heiniu Mountain in Guwu Town to assist the archaeological team, and after entering Guwu Town, Shen Yifan was surrounded by the residents of Guwu Town, and finally after Shen Yifan's statement, the townspeople had nothing to say.

After everyone dispersed, Shen Yifan, Professor Wang and others entered the town government and held a mobilization meeting for the rescue archaeological excavation of Heiniu Mountain.

Professor Wang asked, "Xiao Shen! What do you think is the problem with this tomb complex? ”

Shen Yifan said: "I don't understand the professional issues of archaeology. However, I want to say that there are still four unexcavated ancient tombs at the foot of Heiniu Mountain, and these four ancient tombs are dangerous. ”

The participants were in an uproar when they heard Shen Yifan's words, and one of Professor Wang's students asked: "Consultant Shen, I want to ask, our current high-tech instrument has not yet discovered that there are four unexcavated ancient tombs under the Black Bull Mountain, what evidence do you have to prove it?" "Professor Wang's student is a tall young man, a few years younger than Shen Yifan, and he looks a little naïve, but the question he mentioned is what many people think.

Shen Yifan smiled and said: "Actually, this doesn't use any instruments, our ancestors have already had a way to correctly observe the situation and location of the ancient tomb more than a thousand years ago, and some people even see the layout and mechanism of the ancient tomb palace just by the trend on the ground of the ancient tomb." ”

"How is this possible?"

"That's right! It's a bit of a big blow. ”

Shen Yifan still smiled slightly, walked to a whiteboard and drew a very simple sketch, and said, "This is Black Bull Mountain." As he spoke, he nodded a few dots above the sketch of the shape of the mountain and said: "This is the Yishou Star Palace, which is a constellation that is not easy to find with our naked eyes. Shen Yifan drew a river on the side of the mountain and said: "This is a river in front of Heiniu Mountain, which just separates the main body and the lower part of Heiniu Mountain. In ancient times, it was written that the tomb of this terrain was a dragon's yin, and the water vein was very rare. If you insist on explaining, you can only say that the ancients built the tombs according to Feng Shui Kanyu to choose the site. ”

Many of the students sitting below were not participating in archaeology for the first time, so they naturally knew this truth, and one of the female students asked, "Consultant Shen, can you explain why the advanced remote sensing instruments cannot detect the shape of the ancient tomb and underground palace." ”

Shen Yifan said: "Although remote sensing detection detected a huge space below the river surface, it could not detect the shape of the space because the ancients did not modify the space below the river surface, but only put the ancient tomb into it. ”

Another student also asked, "But we only found that there is a space under the river, but we didn't find that there is an ancient tomb in the mountain?" ”

Shen Yifan thought for a while and said, "This may be a special rock in the mountain that disturbs the detection. ”

Just as everyone was in the middle of the discussion, a worker who was excavating an ancient tomb in Heiniu Mountain walked in and said: "We dug a very special rock formation, a very hard machine on a white spot, and we couldn't dig it at all. ”

When Professor Wang heard this, he said, "Let's go to the scene and have a look." ”

When he arrived at Heiniu Mountain, Shen Yifan felt what it meant to be impregnable, the three layers inside and the outer three layers were all military and police, and if he didn't have a pass, he wouldn't want to enter Heiniu Mountain at all. Everyone came to Heiniu Mountain with the workers, and when they came to the excavation site, everyone was surprised.

It turned out that the layer of rock was as white as snow, and the excavator didn't move when it went down, there were only a few white traces, Shen Yifan touched it with his hand and sniffed it, and said: "This is not a naturally formed rock layer, it is an artificial rammed earth layer." ”

Everyone was surprised when they heard it: "It's already so deep here, and there is a layer of rammed earth?" ”

Shen Yifan looked around and said, "Let the workers dig up all the layers here first." ”

Professor Wang was a little puzzled and asked, "Is this too much work?" ”

Shen Yifan explained to Professor Wang as he walked: "This rammed earth layer is a secret soil layer in ancient times, and its firmness is comparable to cement, and the only way now is to dig up the plane here first, and then consider how to crack it." ”

When Professor Wang heard this, he suddenly realized and said, "Is it the same principle as red glutinous mud?" ”

Shen Yifan nodded and said, "Almost!" But I haven't seen this kind of rammed earth, so I don't know if the ancient method is effective? However, we still prepared early and arranged for someone to buy vinegar first. ”

After hearing this, Professor Wang nodded and said, "Okay." Thinking about it, he asked, "In your experience, what is the layout of the tomb underneath?" ”

Shen Yifan glanced around again and said, "I can't see it for the time being."

I can't see the layout of the tomb below until the surface layer is cleared. ”

Two days after this incident, Shen Yifan was called by Liu Yao early in the morning, and hurriedly came to Heiniu Mountain, and after inquiring on the way, he learned that the surface soil layer of the Heiniu Mountain archaeological site had been almost cleaned up, but a very strange structure was found.

When Shen Yifan came to the archaeological excavation site, he was dumbfounded when he saw the surface results cleaned up, the white rammed earth layer in front of him was actually round, there were three circles, and the three circular finished characters were arranged, and the diameter of each circle reached 100 meters, and it was a full 100 meters, no more than half a millimeter and no less than half a millimeter.

Professor Wang had already taken the students to measure the size on the white rammed earth layer, and Shen Yifan came to a round white rammed earth layer to look at it, and said to himself: "Round? What's going on round? ”

At this time, Professor Wang came over and said, "Brother Shen." Have you ever seen this kind of burial structure? ”

Shen Yifan said: "I have seen a lot of places with round skies, but I have never seen this kind of character with three circles." ”

"I have been doing archaeology for 30 years, and this is the first time I have encountered such a situation. ”

Shen Yifan looked at the three circular white rammed earth layers of equal area, suddenly thought of something, and said, "Professor Wang, have you ever measured the distance between this rammed earth layer and the underground river of the mountain. ”

Professor Wang also had an epiphany when he heard this, and said, "You mean, this could be three tombs?" The tomb goes down like a cylinder? ”

Shen Yifan nodded and said, "If that's the case, it can explain the statement that there are still four ancient tombs in Heiniu Mountain that have not been excavated." There are three circular tombs in the shape of a zigzag, above the most important tomb, and below the underground river is the last and most important tomb. ”

At this time, one of Professor Wang's students ran over and said, "Professor! What do we do next? ”

Shen Yifan said: "In my experience, vinegar can soften the secret rammed earth is a way to pour vinegar on the white rammed earth layer to see if there is any change. ”

More than two hours passed after this sentence was said, the dark vinegar was actually absorbed by the white rammed earth, and after two hours, there were no impurities on the white rammed earth, everyone was staring at each other with big eyes, and even Shen Yifan was a little surprised this time.

Professor Wang said to himself: "The rammed earth layer of an ancient tomb in the Xia Dynasty is actually helpless for modern people? ”

Shen Yifan squatted on the rammed earth layer and looked at it for a long time, pulled out the dagger from his waist and stabbed it hard, it was as hard as steel, but there was no movement except for some powder and a shallow trace.

Shen Yifan picked up some powder and smelled it, and finally he licked it with his tongue, and then quickly spit it out and said to himself: "There is a salty taste, is it Mithril salt earth?" ”

Shen Yifan immediately asked Professor Wang to light a bonfire on a circular rammed earth layer, so that everyone was hidden behind the stones, and after about an hour, he saw a crackling sound on the rammed earth layer burning the bonfire, and then a very unpleasant smell spread.

Shen Yifan hurriedly covered his neck around his mouth and nose and said, "Cover your mouth and nose, this smell is poisonous." ”

After half an hour, a rumbling sound was heard, and a ball of fire rushed directly into the sky from below, and Shen Yifan looked at the bottom hole in the rammed earth layer of the bonfire.

Shen Yifan asked everyone to leave the excavation site of Heiniu Mountain, and after all the poisoning gases in the mountain were dissipated, he used this method to concoct and open the remaining two circular rammed earth layers, and explained that he had to bring a gas mask.

Professor Wang was also amazed and asked, "Brother Shen." How did you come up with the idea? ”

Shen Yifan said: "In ancient times, there were three kinds of rammed earth of ancient tombs that were unique to the royal family, one was red glutinous mud, and the other was the Xuan Ice Layer, which could only be used in icebergs or extremely cold places, and the other was Mithril salt soil. ”

Shen Yifan said: "Mithril salt clay was actually lost in the Tang Dynasty, because Mithril is a very difficult mineral to find, and the secret recipe of this rammed earth has long been lost. It is said that this rammed earth is mainly composed of mythril and mineral salt, and the only thing to fear is fire. However, tomb robbers generally do not use fire to destroy the rammed earth layer, for fear that the embers will destroy the contents of the ancient tomb, so few people will think of using fire as a method. In fact, they didn't know that in the middle of the Mithril Salt Earth, the ancients would put something called Heavenly Oil, which is said to be an animal ointment, which will explode immediately when it encounters fire, and rush everything into the sky. ”

After hearing this, Professor Wang nodded and said, "Thanks to your help this time." ”

Shen Yifan said: "The only drawback of using fire to destroy the rammed earth layer is that the smell of Mithril evaporated inside is poisonous. If you don't protect yourself, you will be dizzy and vomiting, and in severe cases, you will go into shock. ”

Shen Yifan didn t finish saying this when he saw several students being carried down the mountain with a very ugly face shen yifan told professor wang not to worry although he was in the middle

Poisonous, but not life-threatening.

It took a week to destroy the rammed earth layer and strengthen the rammed earth layer, and it was only on the Monday of the second week that all the preparations for the tomb were arranged, Shen Yifan was worried that these theoretical people were in danger and decided to take the equipment community alone, Professor Wang said that he didn't agree with anything, and in the end everyone was deadlocked, and in the evening, Shen Yifan didn't care how Professor Wang persuaded him, and he didn't care about sliding down from a circular ancient tomb with the help of a cable with his own equipment.

With the help of the strong light overhead, you can see that this ancient tomb is indeed a circle as Shen Yifan guessed, and it is already in the end within ten meters of sliding down, Shen Yifan lit a flare, raised it above his head, looked around, and found that there was nothing around, and the only thing he could see was that the circular tomb wall was a coherent mural.

Shen Yifan looked at the air detector and judged that there was no problem, so he took off the gas mask and said to the walkie-talkie: "I've come down, it's safe down there." ”

When Professor Wang heard this, he couldn't wait to go to the tomb, and when Professor Wang, Liu Yao and others came to the circular tomb, Professor Wang looked at the mural and was a little excited.

There are five people in the tomb, in addition to Professor Wang and Liu Yao, there are three students, one of the two men is a big man with a simple head, we will call him a big man here, there is also a female student named Lin Yu, and the other is Professor Wang's protégé named Wang Yunfei.

Professor Wang looked at the mural and said, "This is the style of the Xia Dynasty, and it should record the life deeds and occupation of the tomb owner." Judging from this fresco, the owner of this tomb should have been a wizard of great status at that time. ”

Shen Yifan looked at the mural and said: "Judging from the mural, this guy hasn't done anything in his life, the only thing he has done is to keep guarding a monster, a monster with a wolf's head and a human body." ”

Wang Yunfei said: "This monster? Kind of like ......"

The big man said, "It's a bit like the god of death in Egyptian mythology." ”

When Shen Yifan saw this, he immediately thought of the monster with the lion-faced human head in Beidou Mountain, and wondered if it would have something to do with it.

Lin Yu looked around and said, "There is nothing else here except the murals, is there not even a coffin in the tomb?" ”

Shen Yifan looked at it with a fixed water plate and said: "The Fuxi gossip prevailed in the Xia Dynasty, and there was the so-called sixteen heavenly hexagrams, and the sixteen heavenly hexagrams were based on the circle. Shen Yifan looked at the mural and said to himself: "The sixteen heavenly hexagrams are unfathomable, won't it be easy?" ”

Shen Yifan looked at a mountain on the mural and the river at the foot of the mountain, the flashlight shone through, and found that there was an obvious indentation, Shen Yifan touched the trace with his fingers, and felt a violent tremor under his feet, and then the circular ground began to rotate slowly, and after a while, he saw that the Bagua Gen and Xun each had an entrance, and both entrances had stone stairs leading to the bottom.

When Shen Yifan saw this, he understood and said: "One life and one death!" ”

Professor Wang nodded and said, "It is very much in line with the ideas of the ancients, one thought is life and one thought is death." The question is which one is raw? Is that death? ”

Shen Yifan looked at the fixed water tray and said: "The fixed water tray shows that the middle of the Great Heaven Week is the Gen position Chengji. I guess it's a gen? ”

When Liu Yao heard this, she hurriedly pulled Shen Yifan and whispered, "Don't you guess? It's going to kill people. ”

Shen Yifan smiled and said, "It's okay!" I'll go down first. ”

Liu Yao was a little dumbfounded when he heard this, and before he could react, he saw that Shen Yifan had already gone down the stairs of the Gen position, there was no danger all the way down, and there was nothing on the stairs, just big stones made of stairs, when Shen Yifan finished walking the stairs, he found that the space in front of him really had nothing else except a coffin, and the mural at the end of the coffin had four words written on it.

Shen Yifan said: "It's here." Here are four words, you guys come down and take a look. But the other side of the walkie-talkie did not respond, and then Lin Yu was heard screaming, and Shen Yifan heard a sentence in his mouth: "Damn!" ”

Hurriedly rushed up in three steps and two steps, and saw that the original layer was empty on the upper floor, Shen Yifan thought that everyone had entered the Xun position, and he wanted to enter the Xun position to see what was going on, but when he saw that there was something wrong with the place where he was staying now.

Shen Yifan looked around at the murals around him and said to himself: "Damn! The maze is there again. ”

It turned out that Shen Yifan didn't pay attention to the surrounding situation after rushing up the stairs, but when he went up, he found that the mural was different, and Shen Yifan came to another circular space and lost contact with Professor Wang and them completely.

Shen Yifan entered one of the tombs on the second floor of the bottom of Heiniu Mountain, but heard the screams of the archaeological team, and when he joined the archaeological team, he found himself in another tomb space.
