With a drop of more than 800 meters, the mechanical nest covers an area that is not inferior to that of a medium-sized city, much larger than expected, but judging from its design, it is simply not a design at all.

The mechanical nest has no aesthetic sensibility at all, and it is not the utilitarian simplicity of the wilderness, its appearance is bloated and large, and the dense caverns are enough to dazzle and cause intensive fear, and even physical discomfort, such as dizziness and nausea.

Who will make the place where he lives this virtue?

This is simply a super-sized ant mountain!

Are there all insects living in it?

Such a bloated and complex design is anti-human!

It's so strange, a world that has been completely abandoned for tens of thousands of years, suddenly popping up in front of the mother-nest-like all-metal building, this weird and abrupt feeling, so that Yunying is a little incomprehensible.

Cloud Eagle has traveled through a lot of space, all the worlds it has been to have been destroyed, and there are no intelligent beings, why is there such a huge and strange building in this world?

Yun Ying believes that strange mechanical beasts do not appear out of thin air, and he also believes that the appearance of anything has its inevitability, and this giant mechanical nest must have a reason for its appearance here.

Just go in and have a look.

Yun Ying is not an ordinary person, and he can get out of the worst of his life.

If we don't investigate this oversized nest clearly, how can we rest assured that the people of Green Alliance can live in this space?

The interior of this massive structure is more neat than expected, with thousands of interconnected passages, made entirely of metal, and finally forming a large labyrinth that you can't get out of if you are trapped inside. In the process of Yunying's advancement, he found that many intelligent production areas were fully automatic without anyone to operate.

Those manufacturing equipment are very sophisticated.

All parts are made in 3D using a precision and ultra-high-energy high-intensity laser.

All the transportation of materials and the coordination of components are dazzling, and the most cutting-edge manufacturing processes are all reflected here, but it is very strange that not a single living creature is seen.

Cloud Eagle even suspects that this planet is not a regular civilization.

Rather, it is a unique mechanical civilization, so there are no living creatures.

Perhaps this huge mechanical nest itself is a super huge robot, and it is just in its own right, in order to confirm this conjecture, Yun Ying released the little monster bird to investigate.

The results are viewed in a circle.

There is really no ghost in the huge space.

However, the little monster bird seemed to be alarmed during the reconnaissance process, so that the ceiling above Yun Ying's head was suddenly opened, revealing black pipes from inside, and there was a noisy sound coming from the pipes, and then a large number of giant bee-like mechanical monsters drilled out, the number was amazing, dense, and extremely fast!

Almost rushed out in a swarm.

Was it discovered?

Yun Ying is not afraid of these mechanical monsters, but he came here single-handedly, just to investigate the truth here, find the leader of the other party to try to negotiate, and try to solve the problem by peaceful means, not to start a battle, so the contradictions that can be avoided should be avoided as much as possible.

Space distorted.

When the Giant Mechanical Peak is ready to attack.

The target in front of them simply disappeared.

The giant mechanical bees spun in place.

Although this super-large mechanical nest was very complicated, for Yun Ying, who was proficient in spatial ability, it was basically unable to form any obstacles, and he went directly into the distance of dozens of miles to the hinterland of the mechanical nest. He noticed that although there were no exhaust ducts in sight, the air inside was flowing well, and all the hallways were signaled.

That's weird.

The machine does not need air.

The machine also does not require any instructions.

In this huge metal city, there is actually a normal intelligent creature living in it? Yun Ying was just holding this thought, when he suddenly felt footsteps in front of him, and several figures quickly rushed out and stopped in front of Yun Ying.

Not a machine!

Several people were covered in gray protective armor, with a large helmet on their heads, and they couldn't see what they looked like, and they held spear-like weapons in their hands, and brilliant electric sparks were emitted from both ends, which could instantly paralyze people as long as they came up on people.

"You...... What are you?"

"Why is it here?"

Yun Ying's greatest surprise was not a few humanoid creatures that jumped out, but the language used by these people, and he could actually understand part of it! Although the pronunciation was very strange, the grammar was very problematic, and there were many unintelligible notes!

However, if you listen and guess, you can understand the general meaning.

This is clearly from the language family of the main world, and this is indeed a different world, two different worlds, not to mention that the civilization and even the race are completely different, why do they use such a similar language.

Yun Ying opened his mouth and asked, "Who are you?"

Several people also seemed to sense the strangeness of Izumo Taka.

This guy showed up here without any protection?

No matter what, this stranger appears here, which means that there must be a problem, and listening to him speak, the accent is so strange, take it down first and then interrogate it clearly. It's just that just when a few people were about to attack with electromagnetic spears, something happened that they never expected.

Yun Ying just waved his hand lightly.

All four of them were catapulted out by an invisible force at the same time.

Several electromagnetic spears came out of their hands, and the volley spontaneously combusted in the air and was burned clean on the spot by the green flames.

Yun Ying frowned, it's really strange, the four of them are weak, although they are wearing special armor, but they just fell so lightly, they actually fell to the ground and couldn't get up for half a day, how did such a fragile creature live in this world?

Wave again.

The air around them flowed, like arms, grabbing the four people on the spot.

Yun Ying floated in front of several people: "Let me ask again, who are you and where is this?"

What is this? The legendary superpower? The four of them were all shocked in their hearts, they clearly felt that they were in front of each other, just an ant that could be pinched to death at any time, and one of them reacted and quickly slapped it on the helmet.

"Stop!

The inky black helmet mask suddenly became transparent, revealing a face from inside, this is a young human face, about thirty years old, with short black hair and eyes, it turns out that in this set of defensive armor, it is actually a human body, but this is even more bizarre, why are there humans in the other world?

"I see!" said the black-haired man, "You are what our father said of an outsider! You are a new human from the earth! No wonder you can appear in this place without any protection!"

Father?New Human?

Yun Ying was a little confused.

It's not the same as you expected.

Yun Ying said directly: "I want to see your leader!"

Although there were differences in accent and grammar, there was no obstacle in half-listening and half-guessing, and several people looked at each other, and finally they were happily unified, and the black-haired young man said, "You let us go first!"

Yun Ying is not afraid that these guys will play tricks, after all, in Yun Ying's eyes, they are simply inferior to ordinary people.

"It's amazing! I didn't expect the legend to be true!" the black-haired man's eyes were full of disbelief and shock as he looked at the burnt electromagnetic gun.

Yun Ying was led into the underground passage, first through several layers of metal gates paved with thick lead, and various repeated inspections and disinfection before finally entering the city hidden under the metal lair.

"What the hell is this place?"

Yun Ying was completely stunned by what he saw.

The city is beneath a metal nest, and its scale is much larger than expected.

When Yun Ying raised his head, the dome he saw turned out to be a deep blue sky, thin clouds spread out in the shape of fish scales, and the sun shone with dazzling light, but Yun Ying knew very well in his heart that it was impossible to see the sky here, and the sky in Ishihara was not like this at all, and the sky he saw was actually some kind of high-tech projection.

As for the city?

It's bigger than you can imagine!

Huge buildings, tall buildings, dense streets, endless flow of hovercars, streets full of shops, billboards and the words of the shops are written in ancient earth script, people are dressed in ancient costumes, and they are living in an orderly manner.

A gigantic human city hidden in a labyrinthine lair?

"Welcome here. The black-haired young man came to Yun Ying, he had already taken off his heavy protective clothing, "Our city has a population of about 10 million, in front of it is the Asian region, where is the European region, the African region, the North American region, etc., the name of this city is Earth City, my name is Xiao Kewen." ”

Yun Ying said, "You are all earthlings?"

"Yes, but strictly speaking, we are real earthlings. Xiao Kewen said as he walked: "Fifteen hundred years ago, in the early stage of the cataclysm, the only remaining remnants of the earth were transferred here, and then under the protection of my father, we finally started a new life, and in more than a thousand years, our population has increased from more than 100,000 to a hundred times, so we have the scale we have now." ”

"Why do you claim to be a real earthling. Yun Ying was very strange: "Is there something different between us?"

"No kidding, do you know how strong the energy pollution and radiation of the earth after the cataclysm is? Even this world, which has been barren for tens of thousands of years, is filled with a lethal amount of radiation! If the old humans appeared on it without any protection, they would have all kinds of symptoms in thirty minutes at most!"

"Why don't I feel anything. ”

"Of course!" Xiao Kewen looked at him and said, "Your ancestors were transformed by external civilizations after the cataclysm, and then eliminated and multiplied from generation to generation in a polluted and radioactive environment, and you are the new humans who finally survived and stabilized! Although your appearance is very similar to ours, the essence has been greatly different, and it is impossible for the old humans to exist on the earth now." ”

At this point, he paused abruptly.

"This is the last human city!

Yun Ying felt that a doubt in his heart had been solved, and he finally knew why more than a thousand years after the end of the war between gods and demons, the earth's environment had undergone such tremendous changes, all living beings were evolving and mutating frantically with each passing day, and human beings were increasingly possessing superpowers and mastering spiritual energy.

All this was not possessed by ancient humans.

All this came after the cataclysm on Earth!

This city was actually built by a group of ancient old humans, and their bodies still retain the state of humans thousands of years ago, without any evolution, without any mutation, and there will be no so-called demon hunters, so it is so fragile in Yunying's opinion.
