Fortunately, the seasons of the cave world change very quickly, and soon the muddy winter and spring will pass, the snow melt water will completely seep into the ground, the road surface will gradually harden, and the surging beasts will also taste the power of bullets and knives, leaving behind thousands of corpses.

These corpses alone were enough to feast the mouths of later predators, and there was no need to continue to keep an eye on humans.

Only then did the team break through and sail towards the possible location of the ancient ghost town that had been explored in advance.

Although the authorities have explored the world in the cave more than once, first, this is the intersection of the three realms, the space is distorted, and there are many folds, which is simply boundless, and no matter how much the authorities explore, they can figure out at most 10% of the environment of the world in the cave.

Second, the aura of the world in the cave is impacted, the elements are agitated, and the earth's crust changes are very drastic, and within three or five months or even three or five days, the evolution of the vicissitudes of life can occur.

Mountains will turn into deep valleys, deep valleys will become lakes, lakes will become oceans, and the maps that have just been mapped three or five days ago will soon become unrecognizable, without any reference value, and will lead people into deadly traps.

Therefore, the six of Chu Ge could only rely on the latest maps surveyed and mapped by the advance team in the last one or two days - even so, they often encountered floating mountains that had just broken away from the ground in the past two days, or even in the past few hours, and had just risen from the ground, or floating mountains that fell from the sky, and slammed into crater-like craters on the ground.

They have to revise the data and markings on the map at any time, and they have to figure it out step by step.

This made it quite difficult for them to find the ancient ghost town.

But six hours later, they found the first primeval ghost town.

This is spring in the cave world, the best season of the year.

The wind and the sun are beautiful, everything is revived, and there is even a beautiful rainbow hanging in the blue sky like jewels, take a deep breath, look at the rainbow, everyone feels relaxed, tired and painful, as if breaking free from a never-ending nightmare.

In such a fairyland-like environment, they climbed over a hill like the back of a giant dragon, looked over the lush hillside, and the flower fields blooming at the foot of the mountain, and saw the golden and brilliant city.

In an instant, Chu Ge felt as if he had been hit by an invisible giant hammer in his brain, and he couldn't help but hold his breath.

It's a ...... A city that only exists in fairy tales or even myths.

Combining antique elegance and a sense of future technology beyond the times, it is like a criss-crossing three-dimensional labyrinth, but it is orderly and has a natural sense of beauty.

Compared with this exquisite labyrinthine three-dimensional city, the so-called "nest capital" of the Earth Alliance is really as primitive, rough and ridiculous as an insect nest.

Chu Ge saw that in this city, countless spire-like buildings were rising from the ground, and the spires of each spire were surrounded by countless star-like balls, faintly exuding extremely rhythmic spiritual energy fluctuations.

This is like some kind of energy system, which can continuously draw inexhaustible aura from between heaven and earth, and realize the automatic and eternal supply of energy for the entire city.

He also saw that on the arc-shaped orbits that bloomed like heavenly maidens, there were countless capsules speeding along the tracks, several times faster than the cars and even airplanes of the earthlings, transporting passengers and supplies to all parts of the city in an instant.

On several occasions, two capsules on intersecting tracks were about to collide with each other.

But there is always one of the capsules, which is just the right half beat slower, and narrowly passes by each other, only a hair's length away from each other.

This scene made Chu Ge think of the extremely precise industrial manufacturing process controlled by the computer, and he was almost fascinated by it.

"All this...... Is it all true? ”

Chu Ge muttered.

Everything in front of me is too abrupt and weird, like a mirage.

"Look at the detector on your wrist."

Li Jianguo gestured.

Chu Ge raised his wrist and aimed his tactical watch at the ancient ghost town.

The detection chip embedded in the tactical watch suddenly "beeps and beeps" to give a series of data.

The data showed that there was an extremely strong psychic energy fluctuation ahead, which was a rare high-energy reaction.

At the same time, a strong metal reaction was also detected, proving that in the location that Chu Ge saw, there was indeed a behemoth made of metal.

"It turned out to be ...... It's true? ”

Chu Ge is like a dream, and it feels incredible.

Neither an illusion nor a mirage, but a living primeval city, and a living primeval city, appeared before them.

How is this possible?

Chu Ge was completely fascinated by this magnificent and exquisite city, knowing that it might be dangerous to rashly contact the Tai Gu people, he still couldn't help it, and was the first to walk down the hill.

Li Jianguo and the others who had seen the mysterious and unpredictable powerhouses of the ancient ghost city did not stop them, but just watched Chu Ge quietly from behind.

Around the ancient ghost city, magnificent camouflage like the aurora bloomed, like colorful yarn, layer by layer fell on Chu Ge's head, body, and hands.

Chu Ge was dazzled and couldn't help but stretch out his hand towards the ancient ghost city.

The brilliance of the primeval ghost city seemed to be really within reach, and even the primeval people in the city turned their heads to look in the direction of Chu Ge.

Chu Ge saw in a trance that the size of the Taigu people was slightly larger than that of the earthlings, and their heads were twice that of the earthlings - perhaps because of their highly developed intelligence, they must have a huge and friendless brain to carry it, and in order to dissipate heat from the brain, their hair showed an ice-crystal-like texture, as if it had become some kind of metal, which greatly improved the thermal conductivity and heat dissipation area.

The metallic hair makes them look a bit like a combination of carbon-based life and machinery.

At the same time, on their exposed skin, they were also painted with mysterious and intricate patterns, as if the most delicate circuit board was printed on their bodies—Chu Ge didn't know if this was their naturally grown pattern or an acquired depiction.

In short, these circuit board-like patterns can help them naturally absorb the aura of heaven and earth.

Chu Ge thought to himself, the ancient people with this kind of pattern may not need to cultivate as hard as the earthlings, they can automatically absorb the aura, moisturize and cleanse the body, and gradually become an "innate spirit body"!

This kind of speculation made Chu Ge more and more excited, and he really wanted to find a Taigu person immediately and ask everything clearly.

He took a few more steps towards the ancient ghost town, completely bathed in the unpredictable aurora.

But in the next second, just as he was shouting towards the ancient ghost city, the aurora suddenly trembled.

It's like a fairy tale embedded in a glass ball, which appears to be cracked and shattered.

It's like a hazy dream, stimulated, and finally wakes up.

The ancient ghost town suddenly froze, as if it had lost all life in an instant.

The orbs on the minaret used to absorb the aura of heaven and earth, the galloping capsules in the orbit, and dozens of kinds of facilities and instruments suspended above the city, the structure is so exquisite that Chu Ge can't identify the purpose of the facilities and instruments at all, all of them are still and motionless.

The Taigu who looked at Chu Ge blankly, his eyes were also full of stiff and mysterious light.

They seemed to have endless information to tell Chu Ge.

But after all, after a faint sigh, it turned into a thin sand-like nothingness.

The whole primeval city is like a tower built on the beach, peeled and weathered and disintegrated by the strong wind, starting from the facilities suspended in mid-air, the balls that haunt the minaret, and the minaret, crumbling inch by inch into a rainbow of smoky sand.

"Don't-"

Chu Ge ran faster and faster, reaching out towards the collapsing primeval city, as if he wanted to grasp a fragment of the dream.

But the speed at which the city collapsed and disappeared was always faster than the speed at which he ran and stretched out, as if hanging him unhurriedly in front of him.

By the time he reached the outskirts of the city, it had turned into a clear, colorful sand that looked like a rainbow corpse.

And when Chu Ge wanted to pick up a canopy of colorful fine sand that made up the city, these sands, like spring water melted by snow, seeped into the ground and disappeared without a trace.

What appeared in front of Chu Ge was a valley of thousands of ravines, and there was no sign of the existence of the city at all.

Chu Ge did not give up, knelt on the ground, and dug hard into the ground, wanting to dig up evidence of the existence of rainbow sand underground.

But after digging for a long time, it was always black and swarthy mud, and under the mud was a hard rock formation, and there was not even a single crystal clear sand and gravel to be found.

He really couldn't tell whether what he had just seen was real or hallucinating.
