Chapter 468: Ghost Wall and Snake Palace

Just like that, the city in the sky flew very smoothly.

On this prairie, the next generation of children received a completely new education model.

The effect seems to be quite good.

No matter how people teach, they will never be able to learn; but if things teach people, they will learn it in one go.

Once again, 19 months passed.

The fertility of this grassland is far inferior to that of the underground fissure, but fortunately it has not been explored by other civilizations, so it is not barren.

Thanks to the efforts of the treasure-hunting team, the idealistic minerals of human civilization have barely balanced their income and expenditure, but it is extremely difficult to significantly fill the national treasury.

And perhaps it was due to luck, the wealth dug up in the past six months has been slowly decreasing.

"I really want to find a big mine! I've really been out of the game these past few months."

Lieutenant Colonel Lu Ying rolled off the "Flying Dragon" and yawned in boredom.

He took out a camera and uploaded the captured map to his computer.

By piecing these maps together, we can restore a small part of the real topography of Pangu Continent - this work actually lasted for a long time, from Lu Yuan's manual drawing more than a hundred years ago to computer drawing today. Although technology is advancing, the work is the same.

"In 19 months, we have advanced 68,000 kilometers... This grassland is really huge. How many times larger than the equatorial radius of the earth?"

Lu Ying muttered to himself. He fiddled with the computer for a long time, but found that there were always some contents that could not be pieced together, and he didn't know what was wrong.

He made a phone call: "Brother Yun, there is a big problem, please help me deal with it."

"I'm busy too, Uncle Ying, can you please stop looking for me?"

Hai Zhiyun is very helpless. Ever since the abilities of the humanoid computer were exposed, someone has been asking him for help every other day. It's true that people are afraid of becoming famous just like pigs are afraid of getting fat.

"Brother Yun, I will definitely take you with me on the next treasure hunt. I'll pick up some junk ore for you."

Brother Yun has a hobby, which is collecting garbage. He immediately smiled and said, "No problem, no problem! Just send the document over. It shouldn't be a military secret."

"No, no, no, it's just an ordinary map."

But this time the processing time exceeded expectations. In the past, a job that could be completed in one minute took more than ten minutes.

Hai Zhiyun called back: "Uncle Ying, is this map from today?"

His tone was somewhat serious.

"Yeah, what's wrong?"

"We may have returned to the same place as six months ago... I found that the map is more than 95% similar to six months ago."

"Especially the geographical locations of several large lakes, which are exactly the same." Hai Zhiyun marked several similar lakes with red frames and sent the photos over.

Everything is changing, including lakes and grasslands.

Although the lake was a little shallower than it was six months ago, everyone in the investigation room immediately discovered that it was indeed the same one.

At this moment, everyone was stunned and gasped - it turned out that after such a long time, they just went in a big circle! "What's going on?"

Lu Ying did not dare to delay and immediately reported to his superiors.

This matter soon attracted the attention of the upper parliament.

"It is now certain that we have encountered a ghost wall incident."

"It's serious indeed. All compasses are out of order. Even the rising and setting of the sun is out of order... We wasted half a year for nothing and just went in a circle."

"If we don't find the reason, we might be stuck here for a long time."

Lu Yuan sat in the center of the conference room, looking at the maps, feeling both surprised and confused.

In addition to the compass and the sun, the poppy tree can connect with the sycamore tree in Yunhai City through its dream ability, so it can also know the approximate direction.

But even this kind of guidance failed!

Green City spent half a year and traveled a 21,000-kilometer circle.

This scene is really strange.

"But it's not a life-and-death crisis. We have a lot of supplies with us. Plus, there are dense grass and a lot of wild animals here. This means... we should have enough time to solve this problem."

"If we can get out of this strange place within a limited time, there is no need to rush to inform the public."

“Try going in a different direction.”

Therefore, under the leadership of Lu Yuan, many soldiers increased their reconnaissance efforts. They rode on flying dragons and spent two months searching an area of ​​thousands of kilometers in radius.

But things are so strange, there is almost nothing here except the prairie... Various wild animals live here, survive and reproduce, and it is quite vibrant and looks harmonious.

The three king insects even flew at supersonic speed and tried in all directions, but no matter which direction they flew, they could only fly in a circle of more than 20,000 kilometers and would eventually return to where they started.

Although Lu Yuan has the ability to teleport through space, he doesn't know where to teleport.

The whole world was vast and boundless, covered by prairie, but it seemed to be shrouded by an invisible border. More importantly, he had no idea where this border was.

It is impossible for three-dimensional creatures to touch the boundary of four-dimensional space, just as two-dimensional creatures will never know the concept of "height".

"Things seem to be getting serious..."

After a fruitless day of hard work, Lu Yuan was shocked to think of a very mysterious natural disaster - the strange phenomenon of the [monster]! If he accidentally entered the [monster]'s territory, wouldn't he become like this? Of course, the [monster]'s combat power is not high, and it is good at mental attacks and raising minions.

From this perspective, it doesn't seem likely. Humans have been here for more than half a year and there has not been a single case of missing people, which is inconsistent with the behavioral tendencies of the "monsters".

"Don't let your guard down. The [Monster] is different from other natural disasters. It is as timid as a mouse. Once it finds that the enemy is too powerful, it will not act rashly." Lu Yuan instructed the numerous soldiers, "You continue to scout the surroundings and explore for more clues."

"I'll stay here."

He now didn't dare to leave the city rashly. He controlled the "Greedy Demon" all the time, standing at the top of the poppy tree, staring at the entire city.

Once the monster activates its spatial ability and kidnaps the people, he will immediately activate spatial teleportation and follow them in.

As long as the Greedy Demon God breaks into the [Monster]'s different space, defeating this natural disaster should not be a big problem...

…

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

Then, in the fourth month of waiting, a turning point finally appeared! After a "flying snake" that had been out on a reconnaissance trip returned to the city, the soldiers quickly removed the camera on its head, processed the data using a computer, and fed it delicious food.

There is no other way. The current reconnaissance has yielded nothing. Humans can only expand the scope of reconnaissance from thousands of kilometers to tens of thousands of kilometers. In the case of insufficient manpower, the method of reconnaissance through flying snakes has become the first choice.

In one operation of the Flying Snake, which lasted for 12 consecutive days, the aircraft directly detected a distance of 20,000 kilometers, which was quite cost-effective.

Today’s AI technology has gradually caught up with the level of the Earth in the past. Abnormal conditions in the video can be discovered by AI in less than a few minutes.

Because there has been no information for a long time, the morale of the reconnaissance team is not very good, and everyone is just doing procedural work.

"Beep!" Suddenly, an alarm sounded on a large screen and the fast-playing images stopped.

"This is..." The staff of the identification team suddenly rubbed their eyes and stared at the big screen in disbelief.

A... city! A lonely city floating in the sky? !

The city is not too big in size, about 8 kilometers long and 7.2 kilometers wide. Its overall shape is like a magnificent large palace!

The main building is octagonal in shape, with a hemispherical dome in the center and sixteen small domes around it. The domes are generally engraved with vague patterns that look like the sun god.

A bright blood-red flower filled every corner of the palace, making it look like a city filled with flowers.

An ancient palace with rotten pillars and beams.

The fading light is filled with darkness.

Grayish color, cold light.

The bright red flowers speak of horror.

Everything you see is absurd.

The staff member stared at it for a few seconds and jumped up in fright. Even though this information didn't seem to be anything special, at most it was just that this palace was particularly luxurious and the flowers were particularly red, he inexplicably felt extreme fear, as if he was facing a real natural enemy of life.

After exploring the palace, the "Flying Snake" turned a corner and fled back far away, and the footage it uncovered was very limited.

So investigators can only analyze the video over and over again, trying to find more clues.

“Look here!”

A sharp-eyed worker pointed at a picture.

On one of the platforms, there were some suspicious life forms standing.

It has a slender body, two hands and two legs, a forked pink tongue, and cold eyes that seem to have no focus, looking into the distance.

These snake-like creatures, holding rusty weapons in their hands and wearing tattered armor, people can't even tell whether they are mummies or real living creatures?

“Is this a statue?”

"No, absolutely not."

"Why were they so motionless... They didn't even blink for several minutes."

The leading investigator shuddered and reported to his superiors: "Report! We have discovered a small floating city 8838.76 kilometers northeast. It may be left by a prehistoric civilization. The specific technological level is unknown."

“The images captured by Flying Snake are extremely disturbing.”

After receiving this notice, Lu Yuan did not dare to neglect it.

He first looked at the photos. The mysterious palace decorated with a large number of flowers looked like it had syphilis, which really gave people an uncomfortable and weird feeling.

As for those weird snake people… he couldn't tell whether they were dead or alive.

"Send some drones... No, wait, let's not alert them yet!"
