Wu Haibo's introduction made Meng Chao stand in awe of the Earth warriors on the relief.

You must know that even today, half a century later, the extraordinary people of Dragon City wield crystal swords and psychic firearms to fight against monsters, and the war is still thrilling and arduous.

It is really hard to imagine how the earth warriors who had just traveled through time and had not yet awakened their extraordinary powers could stop ancient monsters that were more terrifying than monsters with their bayonets, grenades and semi-automatic rifles using ordinary gunpowder.

Meng Chao turned around with a solemn expression and bowed deeply to the Earth warriors on the reliefs on both sides of the corridor.

After passing through the corridor, the temperature suddenly dropped by more than ten degrees, as if we had entered a cold storage.

However, what is refrigerated here is not ordinary monster flesh and blood materials, but a ferocious specimen with teeth and claws.

The first specimen was a lifelike humanoid stone statue.

Except for being pale and lifeless, they are exactly the same as humans.

But his right hand was obviously withered, revealing the white bones inside.

It was as if there was some mysterious power that turned most of this poor man's body into stone. Only his right hand still maintained the characteristics of a carbon-based creature.

Meng Chao suddenly thought of what "God of War" Lei Zongchao told him about the deep diver who was lost in the depths of the ancient ruins for five minutes and was dragged up, but was still instantly petrified.

Sure enough, the corners of the stone statue's eyes and mouth were widened to the point of tearing, and the word "fear" seemed to turn into black flames, about to spurt out from the gaps in the stone statue.

Even Meng Chao had never seen such a horrified expression in his doomsday nightmare.

Just with this expression, you can imagine how terrifying the ancient monster is.

The lower body of the second specimen is actually intact human legs.

But his upper body turned into a slowly blooming piranha.

The scarlet petals are plump and thick, covered with green mucus, with shark-tooth-like thorns growing on the edges of the petals, and clusters of shiny stamens like tentacles and nerve cords growing in the center of the petals.

Because the entire specimen was sealed by a crystal-like solidified substance at the moment when its vitality was at its strongest, Meng Chao seemed to be able to smell the sticky and thick scent of rotting and stinking human internal organs emanating from deep inside the flower.

Insert an app: a perfect replica of the old version of the book-chasing artifact and a replaceable source app——.

The third specimen was a deformed man with very uncoordinated left and right sides of the body.

The left half of the body looks like a normal human being.

The right half of his body is deformed and swollen, like a giant three to five meters tall. There are a large number of spiritual patterns on the surface of the body, colorful, and there is almost no inch of clean skin.

Different from the relatively stable and controllable spiritual patterns obtained by extraordinary people through scientific training, the spiritual patterns of the deformed giant are like wildly growing weeds, revealing a taste of chaos, barbarism, and violence, which makes people feel guilty at a glance.

It feels uncomfortable, as if there is some kind of chaotic power inside my body, which is constantly expanding and eager to try.

There are many deformed specimens behind.

They are monsters that normal people would never dream of in their deepest nightmares.

Wu Haibo told Meng Chao that these were monsters, or demons, infected with ancient germs.

The purpose of displaying it here is naturally to remind everyone who goes deep into the ancient ruins of what kind of dangers and secrets they are about to face.

Meng Chao carefully studied these ancient monsters with the eyes of a senior reaper.

One has to admit that their mutations are more deformed than monsters that combine the characteristics of reptiles and mammals.

However, Meng Chao also observed a very interesting phenomenon.

He discovered that the physiological characteristics of many ancient monsters were actually very similar to the physiological characteristics of all races in other worlds in the memory fragments of previous lives.

For example, there is an ancient monster that is about 1.5 meters tall. Its skin is as dark as burnt, but covered with scarlet spiritual patterns. Its canine teeth are extremely sharp and hollow like a needle. It is similar to the "dark elves" and "dark elves" and "dark elves" in Meng Chao's memory from his previous life.

"Blood Race" has different approaches but the same purpose.

Also, the specimen I saw just now, which is small on the left and large on the right, is extremely deformed and unbalanced. It is obviously the product of incomplete evolution.

If the left half of its body were enlarged in the same proportion, it would look very much like the frost barbarians and frost giants, the overlords in the north of the alien continent.

Of course, compared with the alien races that had primitive wisdom and medieval civilization levels in Meng Chao's memories of his previous life, these ancient monsters were obviously more savage, cruder, and rougher, and more like early experimental versions of the former, or in other words, primitive humans.

relationship with modern people.

"Interesting, is there really an intrinsic connection between the various races in the alien world and the ancient ruins?"

Meng Chaoxin said, "Simply relying on the independent ecosystem of a planet in another world will definitely not be able to produce elves, vampires, dragons, demons, undead, magic humans, technological humans... dozens of different carbon species in various shapes and forms at the same time.

Basic intelligent creatures.

"Could it be that the so-called 'aboriginals from other worlds' are not real aborigines, but just like us earthlings, they were summoned here from their home planet by mysterious forces originating from ancient times, and were infected with ancient germs.

Did it slowly mutate and evolve?"

Meng Chao hid this question deep in his mind.

Following Wu Haibo, he passed through the last two specimens with four or five pairs of bat wings and their entire faces covered by tentacles. After passing through a corridor and triple disinfection, he finally stepped onto a new lifting platform.

The movable arc-shaped dome in front of the lifting platform slowly slides open to both sides.

In front of Meng Chao's eyes, it suddenly became clear that there was actually a huge underground space.

"..."

Even though Meng Chao was mentally prepared for the mystery and hugeness of the ancient ruins, he still felt extremely shocked and speechless for a moment.

On the top of the Extraordinary Tower, the Palace of Martial Arts Palace had already astonished him.

This underground palace is at least the size of dozens of martial arts temples, and can easily fit a small town in it.

Because the length and width are so large, artificial light sources cannot illuminate every corner. The edges of the underground space are shrouded in a faint layer of fog, making it visually appear more vast.

Meng Chao concentrated his spiritual energy on his eyes, and when he looked far into the distance, he could barely see that the rock walls in the underground space were covered with densely packed, criss-crossing things that looked like metal pipes.

That's not human style metal pipe.

No, they are not pipes at all, but similar to the internal organs, blood vessels and nerves of living things.

This place is simply like being inside the body cavity of a gigantic metal beast, and they are nothing more than parasites inside this beast.

"etc……"

Meng Chao suddenly felt that something was wrong.

The length, width and height of this underground space must be more than one thousand meters.

How can a super giant space of at least several cubic kilometers, without the support of half an Optimus Pillar, still stand upright under the squeeze of hundreds of millions of tons of rocks?

No, the more important question is, how could there be such a wide underground space under the Extraordinary Tower?

Meng Chao clearly remembered that the area occupied by Chaofan Tower was far less than one square kilometer.

Directly in front of the Extraordinary Tower is the Civic Square, with the office buildings of the Survival Committee on both sides, and the headquarters buildings of several super companies behind it.

The people of Dragon City, who were very calculating and exploited every opportunity, not only crowded the surrounding space, but also excavated a large number of underground buildings with a honeycomb structure. In addition, Dragon City's original air raid shelters, underground shelters and underground weapons depots formed an intricate complex.

An underground world like a maze.

If we keep digging from right below the Extraordinary Tower to the surrounding areas, we will not be able to dig out more than two to three hundred meters, and we will dig into air raid shelters, underground shelters, weapons depots and arsenals.

But as far as Meng Chao could see, everything was empty. Where had all the underground buildings that should have existed in all directions gone?

"It seems that you have discovered the problem."

Wu Haibo smiled slightly and said, "Using the theory of the three-dimensional world, we can't explain the phenomenon of...'space overlap' we see in any case, but the ancient civilization that left these ruins is most likely a 'four-dimensional civilization'

, their method of transforming the world is completely different from ours.

"It's like activated carbon with countless tiny pores distributed inside. If its internal pores are fully expanded, just 1 gram of activated carbon can expand a huge area of ​​1,000 square meters.

"Perhaps, in the three-dimensional universe, an area of ​​just one cubic meter can accommodate an entire city or even an entire planet after being expanded in other dimensions?

"In short, the ancient ruins under the Extraordinary Tower and the underground space of Dragon City are not entirely in the same dimension. You can simply understand that we did not just take an ordinary elevator and reach hundreds of underground spaces.

meters, but made a new journey and traveled to an incredible alien space.

"Only through a very small number of space gaps similar to 'wormholes' can one enter this alien space. If you stand in the Civic Square and dig at an angle, you will not be able to find ancient ruins even if you dig three feet. This is why we

One of the reasons why we took so much pains to build the Extraordinary Tower is to maintain the long-term existence and stability of the space gap."

Meng Chao suddenly realized.

No wonder he felt that the elevator had been running for too long just now, far longer than the time it took to go 100 meters underground.

The space folds and the dimensions expand, it’s incredible!

"This...is the space opened up by the ancient civilization?"

Meng Chao looked around, a little dazed, "What is such a large space used for?"

"As of now, there is no clear conclusion. With the current technological level of people on earth, exploring ancient ruins is no different from a blind man touching an elephant. Perhaps, as I said at the project introduction meeting, there is a 'travel engine' installed underground in Dragon City.

, the whole city is like a super giant spaceship, and this is naturally the 'dockyard' or 'port' for receiving the spaceship."
