Li Jianguo and others surrounded him.

"Is everything I saw just now true or false?"

Chu Ge was stunned, "Have you seen-"

"Yes."

Li Jianguo said, "The first time I entered the cave world, when I saw the ancient ghost city, I was just as shocked and puzzled as you, but we have exhausted all high-tech means to detect, and we are very sure that what you saw just now is neither a mirage nor a mass hysteria, but a real city, and even the residents of the city are alive and have an extremely powerful life magnetic field." ”

"Well, how did they ......?"

Chu Ge licked his lips, still in shock, "Turned into gravel?" ”

"Nobody knows."

Yun Qianhe shook his head and said, "Perhaps, this is the mystery of the disappearance of the primeval people and the demise of the primeval civilization, as long as this mystery is revealed, the origin of human beings, the earth, the immortal cultivation realm and the illusion realm, how the relationship between the three realms develops, there is an answer." ”

"The primeval ghost town will appear once in a while, like a ghost ship that haunts each other, and the time and place of its appearance have a lot to do with the fluctuations of the spiritual energy in the cave world and the surging spiritual tide."

Jiang Li said, "Now, the aura of the cave world is so strong, and the spiritual tide is so surging, I believe that the primeval ghost city will appear soon, we should immediately catch up, maybe, we can see it appear again!" ”

The crowd hurried back to the ATV.

By inputting the coordinates and trajectories of the past ghost towns into the military computer, plus the latest coordinates, as adjustment parameters, you can vaguely predict the coordinates that will appear in the future of the ancient ghost towns.

Light armoured vehicles and all-terrain vehicles rushed out like arrows from a string, speeding between the mountains and mountains, as if riding the wind and waves between the undulating tides.

After more than an hour of bumpy rides, they caught the trail of the ancient ghost town for the second time, before the light armored vehicle and all-terrain vehicle were about to fall apart.

This time, the ancient ghost town stands in a swamp covered with a network of water.

It is obviously a magnificent and glorious city like a mountain, but it seems to be light and weightless, and even the void is suspended on the swamp.

And the water in the swamp is also like being pulled by an invisible force, sucked into the city by a trace, and injected with spiritual power, turning into the blood that keeps the city running.

In the sky above the city, there are also countless primeval people levitating and flying.

Under the reflection of the rising sun, the mysterious and intricate patterns on their bodies like circuit diagrams shine brightly, blooming with colorful and beautiful brilliance.

This brilliance may form an intricate and indestructible armor.

Or form a sharp blade that swallows the sun, moon and stars, and splits mountains and stones.

Or form wings that cover the sky and the sun, helping the ancients to roam between heaven and earth.

Seeing this scene, Chu Ge couldn't help it, and stirred the battle nanomachinery to the limit.

He also grew nano wings, soared into the air, and flew towards the ancient ghost town.

But just like last time, as soon as he entered the range shrouded in the brilliance of the ancient city, he was immediately sensed by the other party.

The primeval people gazed deeply at him, and then the whole city became dim and shattered again like a frightened bud, a television set cut off from power, a crumbling sand tower, and rose like a light smoke, obliterating into nothingness.

Chu Ge swooped down and plunged headlong into the void.

His hands fluttered, trying to catch the last of the primeval afterglow, but only a few ethereal phantoms.

There seemed to be a faint sigh of the ancients in my ears.

If you look closely, it's the depths of the swamp, where the methane rises, rises to the surface, and bursts bubbles.

"I, am I wrong?"

Chu Ge turned around and said with annoyance, "I shouldn't disturb their tranquility, should I let them maintain it for a while longer?" ”

"It's okay."

Li Jianguo comforted him and said, "When we first saw the ancient ghost town, we couldn't help but pounce like you, and we had disturbed the tranquility of the ancient people more than once, but every time they were not angry, and they didn't even react, just like they didn't see us at all, and when they appeared next time, they still looked unhurried, sad and joyless." ”

Chu Ge was stunned and said, "But they obviously saw us, otherwise, how could they collapse and disappear?" If, if they are really 'alive', we have been disturbed so many times in a row, and there is really no reaction at all? ”

"Perhaps, we didn't bother them."

Li Jianguo spread his hands and said, "It's like ants can't disturb any of our activities, maybe in the eyes of the ancients, we are all insignificant beings like ants, and any of our actions are not enough to disturb them—they don't even really 'see' us, it's just our wishful thinking." ”

Chu Ge was stunned for a long time, shook his head and said, "If the Tai Gu didn't care at all, and didn't even see us, how could their city disappear inexplicably?" ”

"Perhaps, it's not that the city has disappeared, it's just that it's entered another state, a state of collapse that the observer can't see."

Yun Qianhe said, "Many space physicists in the Association believe that the ancient city is not a city in the concept of three-dimensional space, but a city that exists on a discontinuous surface of three points and five dimensions between three-dimensional space and four-dimensional space, and when the observer does not exist, it can project a clear projection in three-dimensional space, but once the observer pays attention to it, then all possibilities will collapse into a point, and the ancient ghost town will disappear, and the next wave peak of the discontinuous plane of three points and five dimensions will appear." ”

“……”

Chu Ge's eyes were full of question marks.

"Don't think about it, I also pondered it for three days and three nights and didn't figure it out - it's not a shame."

Li Jianguo patted Chu Ge on the shoulder, "Anyway, our goal is not the ancient ghost city, but through the ancient ghost city, determine the latest coordinates of the hole in the cave, let's go, discover the ancient ghost city again, and you can find the hole in the cave through the analysis of trigonometric data!" ”

This time, they had a lot of luck.

On the top of a mountain, I saw the whole process of the formation of the ancient ghost town.

On the top of the mountain, the clouds and mist were shrouded, and there was nothing but green pines and strange rocks.

But soon, the white clouds turned colorful, as if countless rainbow dragons were flying and tumbling inside.

Immediately after, these rainbow dragons all rose into the sky, turning into brilliant fireworks in mid-air, like heavenly maidens scattering flowers, one after another.

The rain and glow outline the silhouette of the city, which is clear at a speed visible to the naked eye, and in just half a minute, this mysterious city emerges from the so-called "discontinuity of three-point five-dimensional space".

The city is still bustling with traffic.

The primeval people who were hovering over the city to cultivate, meditate, and fight were also the same as always, and they did not feel like they were being reborn again and again.

Seeing such an incredible picture, Chu Ge was thoughtful in his heart.

Perhaps, Yun Qianhe is right.

The primeval city has always existed, never subject to human observation or will.

They just exist in a higher dimension, in a more subtle dimension.

It's as if a human city built on the edge of a lake casts a brilliant reflection in the lake.

The fish in the lake are fascinated by the reflection and try to reach the surface again and again to pursue the truth of the reflection.

But every time the fish burst out of the water, the ripples that stirred would shatter the city's reflection in the lake.

It is not until the fish no longer try to rush out of the water to "see" the reflection that the lake will calm down and the reflection will reappear.

Then, the fish, which has only seven seconds of memory, will be attracted by the flickering lights on the lake and the laughter of the people, and crash into the lake again, knocking the lake to pieces, causing the city in the reflection to "collapse" again.

That's right, in Yu'er's view, it was he who caused the "collapse" and "rebirth" of human cities again and again.

But what they are striving for is nothing more than a projection.

No matter how the projection is broken, chaotic and re-condensed, people living in the city will not feel the slightest feeling, let alone feel that they have been disturbed.

Perhaps, once in a while, when people are bored, they will lean on the railing of the lake and enjoy the beautiful scenery of the fish competing to jump out of the water.

Humans will even look at the fish and see that the fish are looking at the human.

But human beings will never regard the gaze of the fish as an intelligent "observation", and will only laugh it off.

And the splendid and beautiful city of mankind is a place where fish can never reach after all.
