What is the concept of 3,000 squares?

More than seven basketball courts, nearly half a football field.

If it was just a stargazing platform, Li Ding'an would have to wonder if it was built by any emperor of the Liao, Jin, Yuan, and Manchu dynasties, and whether it was a large-scale ceremony to worship the heavens held here by the civil and military forces of the Manchu Dynasty.

If it's a compass...... Ha, what are you kidding?

In addition to exploring the dragon vein, Kanyu geography, mountains and rivers, there are only a few points left in this thing.

Either way, the compass must be removable.

Build it on the top of the mountain with a stone slab, so how can you be embarrassed, how can you point it?

And so big?

Are you buried by God?

It's not an exaggeration at all: he grew so big, except for the day when the phone became fine, nothing surprised him so much.

Whatever you say is also studied.

He abruptly stood up and walked to the center of the podium.

If it is a compass, then there should be a pointer in the center, and the length of this pointer is at least six meters above the radius of thirty meters.

He just wanted to see, if there really is such a thing, what is it made of?

A six-meter magnet?

Stop...... Where did that technology come from in ancient times?

But as he walked, he stopped again.

I walked too fast before, so I didn't pay attention to it, but now that I look at it, the whole roof, that is, the big circle that is suspected to be a compass, seems to be a convex surface?

Slowly raise from the edge to the center.

The drop is not low, the highest to the lowest is more than two meters, but in terms of a radius of thirty meters, it is almost negligible.

If it is a compass, in addition to the center of the pan, the rest of the place can only be more flat and more flat, and such terrain will never appear.

And on the contrary, the center of the pan is concave inward......

"Left Bureau, have you done topographic mapping before?"

"Teacher Li, you said Qinglong Mountain?"

"I'm talking about the top platform, which is this altar...... Why is it convex? ”

"Oh...... Didn't you say before, some people planted land on the top of the mountain, and they were afraid that the rain would be too heavy in summer and it would become a disaster, so they flattened the top of the mountain into a convex ......"

Let's just say why there are no ridges?

And in this way, even if there is a similar stone platform, is it also buried underneath?

Includes disc and pointer......

"Left Bureau, no matter how square or round, have you found any artificially chiseled stone slabs?"

"Never found it again."

"Have you tried to dig in?"

"Huh?" Zuo Peng was stunned, "There are too few physical objects, and I feel worthless, so I just simply inspected it!" ”

Li Dingan didn't know what to say: Director Zuo, Director Zuo, you always complain, saying that you can't touch big projects, why don't you want to think about the deep-seated reasons?

If you find a lot of high-value physical objects at once, can you still leave them to the municipal level?

Just like the Warring States Tomb at the foot of the mountain, as soon as the news was received, the National Museum and the State Administration of Cultural Heritage rushed over, and the provincial cultural relics department could only stand aside.

He sighed and pinched the walkie-talkie: "Team Xing, Team Xing, I'm Li Ding'an!" ”

"Teacher Li, please speak!"

"Draw a group of people...... Forget it, you personally bring a group of people up, and bring all the instruments, including surveying and mapping, geoelectricity, geoacoustics, and geomagnetism...... Then call two groups of masters and eldest sisters (villagers) to bring digging and cleaning tools......"

"Oh...... Got it! ”

As soon as he "sighed", Zuo Peng's eyes lit up, "Teacher Li, have you made a discovery?" ”

"I'll take another look!"

As for the twenty-eight constellations and three stone slabs with inscriptions, it is really difficult to make a conclusion.

The key Zuo Peng dared to think too much, and if he showed him a big needle eye, he would dare to blow the big wind at the mouth of the bowl.

What if it turns out in the end, it's not a compass?

It is estimated that Zuo Peng will cry......

casually perfunctory, Xing Feng also took people up the mountain.

Hulala is a big group, there are more than thirty numbers.

In fact, there is only one technical group (surveying and mapping) and two clean-up groups (migrant workers).

"With me as the center, radiate outward in concentric circles, the concentric equidistance is tentatively set at two meters, and the radius of radiation is thirty ...... Oh no, forty meters ......"

He knew how to do it, and Li Dingan didn't bother to say technical terms, and pointed to the stone slab not far away: "Where is the specimen...... Probe, then dig, and then clean up ......"

Rock slab, what does this have to do with the porcelain kiln?

Just muttered in his heart, Xing Feng's movements were very fast, and the task was assigned in three or two sentences.

Li Ding'an personally operated and explored the center of the circle first.

The mechanic put the radar close to the ground, Li Dingan clicked the screen a few times, and the machine emitted magnetic waves to the ground.

Almost synchronously, the screen displays the scanned image layer by layer, just like a person doing color ultrasound in a hospital, as the fan ripples go deeper, all kinds of data are displayed one by one: soil layer, sand layer, mixed layer, gravel, rock...... Volume, shape, dimensions......

Reaching two meters below, magnetic wave feedback, found a regular rock formation, Li Dingan knocked on the keyboard a few times, and a three-dimensional image was synthesized on the screen

"So advanced?"

Zuo Peng was startled for a moment, and his eyes widened again: more than a dozen geometric rocks, the surface is smooth, thin and thick, and the key is ...... There are a lot of pieces, and the outer edges are all arcs?

Li Ding'an tapped the keyboard again: Nearly 20 stone slabs were put together into a circle?

It is another stone plate, and the size is six meters square.

What is this thing for?

Just turning his mind, Li Dingan picked up the geological magnetometer: "Clean up the group, dig, two meters deep!" ”

"Okay......"

In response, five or six villagers surrounded him, and the impact hammer opened: "Knock knock knock......

Xing Feng was probing the ground more than ten meters away, and was about to scold, when he saw Li Dingan directing beside him, he quickly closed his mouth.

"Change the geomagnetism or geoelectricity!"

After explaining, Xing Feng closed the computer and ran over: "Teacher Li, what did you find?" ”

"There are more than 20 stone slabs, which together are a stone plate with a diameter of about six meters...... Hand-chiseled! ”

"Six meters...... Relic? ”

Li Ding'an glared at him: You were infected by Zuo Peng...... No, you dare to think more than Zuo Peng.

If you only look at the existing physical objects, at most a few stone slabs from the Jin and Liao periods, which remains of Menzi?

It would be nice to be able to call it a "ruin".

Of course, don't talk about it after digging it out......

"Teacher Li, I have a discovery here!"

Li Ding'an raised his head: about twenty meters away from him, it was the circle of the twenty-four mountains that he had speculated before.

"Depth, shape, size?"

"Seventy centimeters deep, close to a perfect circle, one meter ...... in diameter"

Exactly the same as the stone slabs engraved with "Gen" and "Kun"?

Li Ding'an's words were concise and appalling: "Dig ......"

"Mr. Li, I also have a ...... here The depth is one meter one, and the shape is rectangular ......"

"Digging ......"

"Mr. Li, my side is a disc ......"

"Dig ...... too"

"I have a ...... for that too I have ...... here, too."

"Dig, dig it all, I'll transfer people for you......"

Li Dingan pinched the walkie-talkie: "Old Ma, transfer the fourth team to clean up the team for me...... All men want to be men, remember to bring tools? ”

"It's not...... I'm looking for something? ”

"If you don't have enough manpower, you will find Director Zuo to transfer ...... Oh, Director Zuo is here, I'll ask him to transfer, you send someone to me first......"

No matter how late Zuo Peng's reaction was, he also knew that this place was not "worthless" as he said at all.

It's not good that the value is still very large, otherwise Li Dingan would not casually transfer people from the project team.

His eyes lit up: "Teacher Li...... Is it a ruin? ”

Not again?

Just said that Xing Feng was infected by you......

"Don't worry, you have to dig things out, and you'll know after you've seen them...... Transfer people to the old horse first! ”

"Good, good...... Modulation ......"

Zuo Peng ran to the side to make a call, and Xing Feng came over: "Teacher Li, I have also seen the stone slabs on the periphery before, and they look like a sacrificial platform and a stargazing platform." But inside...... Why are there so many slates? ”

You've only dug up a few pieces, and you're too much?

If the altar is in the shape of a compass, then there are at least twenty-four directions, and depending on the equivalence distance, there are at least nine to ten layers, which means that at least more than 200 stone slabs are buried in the ground.

Only then did a tenth of it be dug up......

Li Dingan looked down the mountain: "It seems that we have to build a road and transport the machine up!" ”

"Huh?"

"Otherwise, you won't be ......able to dig until next year by manpower alone."

Just halfway through speaking, a voice came from the intercom: "Mr. Li, I dug out a grinding disc here?" ”

God's millstone?

Li Ding'an pinched the call button: "Go over immediately!" ”

Xing Feng chased closely behind: "Teacher Li, where are there so many stone plates on the mountain?" ”

"I guess it's the compass!"

What's that?

Xing Feng paused suddenly, Li Ding'an didn't have time to wait for him, and arrived at the group he had just called.

Two explorers and four village aunts, each with a shovel. A large pit was dug in the ground, but it was not deep, only forty or fifty centimeters, and in the pit lay a round stone disk.

One meter in size, twenty centimeters thick, and a hole as thick as a shovel handle in the middle, not to mention, it really looks a bit like a grinding disc.

Look at the distance and direction: more than 50 meters away from the center of the circle, and the round stone disk engraved with the word "Gen" is also the same size, roughly judged, the two stone plates are just sandwiched into a 45-degree angle.

One of the 24 mountain directions......

Then this piece is engraved on it, it should be "Xun"!

But if there is no word on this side, then it is on the opposite side!

"Here, take a hand, turn over."

Li Ding'an put on gloves and jumped down the pit, and Xing Feng and the two detectives also jumped down.

The aunt wanted to help, Li Dingan said no, and then the four of them worked together, and with a trumpet, the stone plate was turned over.

Rubbing off the soil around the pit eye with both feet, isn't it the word "Xun"?

Ha...... What is this top of the platform if it is not a compass?

"Xun, gossip one!"

Xing Feng cleaned up the surrounding soil: "But there is no hexagram? ”

Look, it's no wonder that Zuo Peng doesn't pay attention to it, even Xing Feng thinks that it is a stone plate engraved with gossip.

"Team Xing, this is not a hexagram, it is the twenty-four mountain directions."

Li Ding'an pointed into the distance, "That, that, that, and three pieces of the same size were also found, namely 'Gen', 'Kun', and 'Shen'...... So I guess, it's the compass! ”

"Stone compass, still built on the mountain?"

Xing Feng thought about it, and jumped out of the dirt pit with one step, but then, he suddenly paused: "This is one of the twenty-four directions, so what is the place where we stood just now?" ”

"Center of the Circle!"

"You just said that it radiates outward with a radius of forty meters?"

"Yes!"

Xing Feng was completely frozen, and he was stunned: "Doesn't that mean...... This compass is only eighty meters in diameter? ”

Li Ding'an Zhilehe: I finally saw someone who was even more shocked than me......

"Rest assured, not a single piece, but more than two hundred stone slabs, or more...... They are not closely connected to each other, but there is a large blank area, which is many times the total area of the slate......"

"If it's a whole piece, it's an alien ...... it's built on it."

"Haha......"

"It's not...... Teacher Li, don't laugh."

Xing Feng gasped, "I can't imagine at all: how to use this thing?" ”

Li Dingan scratched his forehead: Yes, how to use it?

The point is, what's the use?

To say that it is just an altar...... You can engrave the heavens, the sun and the moon, and the stars, and what do you do with the compass?

I just can't figure it out.

Li Dingan sighed suddenly: "Dig it out and look at it again!" ”

"Yes, dig it out and look at ......"

Xing Feng pointed forward, "Teacher Li, the cleanup team sent by Ma is also here!" ”

"Dig the center of the circle first!"

……

There was great strength in the crowd, and in a short time all twenty stone slabs were dug out and hung up from the pit.

After a little cleanup, they were put together again.

Seeing the whole picture of the stone plate, Li Dingan was stunned for a moment: how is it different from what he imagined?

He had estimated that if it was a compass, it should have a pointer and a center, and the needle was five to six meters long, and the center of the center was slightly larger, and the diameter was estimated to be about six to seven meters.

When the machine probed into the stone disk, the diameter of the synthesized three-dimensional image was only six meters, and he thought that he might have made a mistake in his calculations, and that a slightly smaller center and a slightly shorter pointer were not a big problem.

But then look at it: there is only one stone plate, and there are quite a lot of engraved lines on it: ten concentric circles from the inside to the outside, divided into twenty-four equal parts.

But where is the heart, where is the pointer?

It is clearly another compass, and it is the kind that has not yet been engraved: there is not a single symbol on it except for the engraved lines, including the star map represented by dots and pits.

In the middle, there is a wide wheel with a coil, but it is flat, but the shadow of the pointer is not visible......

Li Dingan lowered his head in contemplation, and Xing Feng waved his hand gently, letting all the people around him disperse.

After a while, he circled around the stone plate a few times and looked around again.

More and more stone slabs were dug up, and there were basically no discrepancies from his previous guess: there were a total of ten layers inside and outside, divided into twenty-four equal parts, with mountain directions, gossip, and star maps.

At first glance, the piece in front of me is a miniature version of the large compass on the top of the platform, but I didn't have time to engrave the words and symbols, as well as the star map.

Again, there are no coils and hands.

But without these two things, what is your compass?

Even the compass can't be explained: the compass is set inside the compass?

It's useless to even open the system: for example, the piece in front of you is two or four words when you measure it: a stone compass.

Measure the rest, what is engraved on it will be displayed: engraved stars will show the stars, engraved directions will show directions......

It's not that I can't recognize it, so why should I measure it?

To be honest, the first time I saw such a strange thing, it was also the first time I felt helpless.

Just scratching his head, the walkie-talkie rang again: "Teacher Li, Teacher Li?" ”

"Roger!"

"I dug out the beams under the cliff, and the purlins and rafters!"

"Old Ma, you can tell me about such things, I'm busy!"

"Teacher Li, wait a minute, there are a few rafters that are a bit strange: there are scales on them...... And tenons and tenons? ”

Li Ding'an didn't want to speak: "It's strange that the rafters don't have mortise and tenon joints, otherwise how can they be connected with purlins and beams?" Not to mention the scale, in the past, when the house was built, there was also the "door Gong Bazi" (the eight characters on the Luban ruler, representing the good luck and evil) "...... on the carved beam"

"It's not...... Blame me, I didn't explain it clearly: the two ends of the rafters are not mortise and tenon joints connected to purlins and beams, but are connected to each other...... The scale on the rafters is according to the size: there are rulers, feet, and quotations......"

Interconnected...... Ruler, zhang, ......

Ten feet is equal to one zhang, ten zhang is equal to one lead, and one lead is about 30 meters...... This means that a single rafter in this house is thirty meters long?

This means that the structure of this room is also 30 meters apart, and there are no load-bearing walls and load-bearing columns in between?

What nonsense?

Not to mention the ancient, but the modern...... Oh no, even aliens can't make it.

Therefore, this is by no means a rafter, and it cannot be a cross burden on any building, because it cannot bear it.

If you want to talk about columns, there is a little possibility.

But thirty meters of uprights ...... Where to stand, and what can you do?

I can't figure it out......

Well, that's not right......

Stand up?

This is the pointer?

The hands of the compass......
