Chapter 468: Ghost Wall and Snake Man Palace

Just like that, the Sky City was flying very smoothly.

In this prairie, the next generation of children received a brand new education model.

It seems to be quite effective.

People teach people, but they can never learn; things teach people, and they can learn once.

Time passed again for 19 months.

The richness of this prairie is far less than that of the underground fissures. Fortunately, it has not been explored by other civilizations, so it is not barren.

With the efforts of the treasure-hunting team, the idealistic minerals of human civilization can barely be considered balanced, but it is extremely difficult to fill the treasury significantly.

And it may be due to luck. In the past six months, the wealth dug has been slowly decreasing.

"I really want to find a big mine! I have really been out of touch these past few months."

Lieutenant Colonel Lu Ying rolled down from the "Flying Dragon" and yawned boredly.

He took out a camera and uploaded the map he had taken to the computer.

By stitching 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 hand-drawing more than a hundred years ago to the current computer drawing. Technology is advancing, but the work is the same.

"19 months, 68,000 kilometers... This grassland is too big, how many times larger than the equatorial radius of the earth?"

Lu Ying muttered to himself, fiddling with the computer for a long time, but found that there were always some contents that could not be stitched 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 am also very busy, Uncle Ying, can you stop looking for me all the time."

Hai Zhiyun was helpless. Since the ability of the humanoid computer was exposed, someone asked him for help every few days. It's really like people are afraid of being famous and pigs are afraid of being fat.

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

Brother Yun has a hobby, which is collecting junk. He immediately smiled and said, "Okay, okay! Just send me the file. 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, the work that could be completed in one minute took more than ten minutes.

Hai Zhiyun called back again: "Uncle Ying, is this map of yours today?"

His tone was a little serious.

"Yeah, what's wrong?"

"We may have returned to the place half a year ago... I found that the similarity of the map is more than 95% with half a year ago."

"Especially the geographical location 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, and the same is true for lakes and grasslands.

Although the lake water is a little shallower than half a year ago, everyone in the investigation room immediately found that it is indeed the same.

At this moment, everyone was stunned and took a breath of cold air - it turned out that after such a long time, they just went around in a big circle!

"What's going on?"

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

This incident quickly attracted the attention of the upper parliament.

"Now it is certain that we have encountered a ghost wall incident."

"It is serious. All compasses have failed, even the rising and setting of the sun has failed... We have wasted half a year in vain, just going around in a circle."

"If we can't find the reason, we may be trapped here for a long time."

Lu Yuan sat in the center of the conference room, looking at these maps, with surprise and doubt in his heart.

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

But even this kind of guidance has failed!

Green City spent half a year and went around a big circle of 21,000 kilometers.

This scene is really strange.

"But it's not a life-and-death crisis. We carry a lot of supplies, and there are dense grass and many wild animals here, which 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 people."

"Try to move in different directions."

So, under the leadership of Lu Yuan, many soldiers increased their reconnaissance efforts, riding flying dragons, and spent two months to check the area within a radius of thousands of kilometers.

But things are so strange. Apart from the prairie, there is almost nothing here... Various wild animals live here, survive and reproduce, and they are quite vibrant and look harmonious.

The three king insects even sailed at supersonic speed and tried in all directions, but no matter which direction they flew, they could only circle a large circle of more than 20,000 kilometers and eventually returned to the original place.

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

The whole world is full of prairie, but it seems to be shrouded by an invisible boundary. More importantly, he doesn't know where this boundary is.

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

"Things seem to be getting serious..."

That day, after a busy day without any results, Lu Yuan was horrified and thought of a very mysterious natural disaster - the strange phenomenon [Monster]!

If you accidentally enter the [Monster]'s territory, wouldn't you end up like this?

Of course, the [Monster] is not very powerful in combat, and is good at mental attacks and raising minions.

From this perspective, it is not likely. Humans have been here for more than half a year and there has not been a single missing person, which is not consistent with the behavioral tendency of the [Monster].

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

"I will stay here."

He didn't dare to leave the city rashly now. He controlled the "Greedy Demon God" at all times, located at the highest point of the poppy tree, staring at the entire city.

Once the [Monster] activates the space ability and kidnaps the people, he will immediately activate the space teleportation and follow in.

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

...

So, in the fourth month of waiting, the turning point finally appeared!

After a "flying snake" that went out for reconnaissance returned to the city, the soldiers quickly took off the camera on its head, processed it with a computer, and fed it with delicious food.

There was no way. The current reconnaissance had nothing to show for it. Humans could 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 became the first choice.

In one operation of the flying snake, for 12 consecutive days, it 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 was no information for a long time, the morale of the reconnaissance brigade was not very good. Each of them was just a programmed job.

"Ding!" Suddenly, a large screen sounded an alarm, and the fast-playing picture stopped.

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

A... city!

A lonely city floating in the sky? !

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

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

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

Ancient palaces, rotten pillars and beams.

The fading light is full of darkness.

Gray and white colors, cold light.

The bright red flowers tell of horror.

Everything you see is absurd.

The staff stared at it for a few seconds and jumped up from his position in shock. Even though this information seemed nothing 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, and the footage it found was very limited.

So the investigators could only analyze the video again and again, trying to analyze more clues.

"Look here!"

A sharp-eyed worker pointed to a picture.

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

They had slender bodies, hands and feet, pink tongues with forks, and cold eyes that seemed to have no focus, looking into the distance.

These snake-like creatures, holding rusty weapons in their hands and wearing tattered armor on their bodies, people couldn't even tell whether they were mummies or real creatures?

"Is this a statue?"

"No, definitely not."

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

The leading investigator shuddered and reported to the higher-ups: "Report! We found a small floating city 8838.76 kilometers northeast, which may be left by prehistoric civilization. The specific technological level is unknown."

"The images taken by the flying snake make people feel strongly uneasy."

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

He first took a few glances at the photos. The mysterious palace decorated with a lot of flowers was like syphilis, which really gave people a very 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, don't alarm the snakes first!"
