277: It’s not a mountain, it’s an ancient city-state!

"Something's happening!"

The crew hastily looked over.

They saw dust flying from the mountain walls of the three great mountains, as if Guo Feng's strike had directly hit them.

"Huh?"

Guo Feng also turned to look.

He scrutinized for a moment, then asked, "Do you feel like these three mountains aren't mountains at all, but rather three square buildings?"

"They do look like it, but how could there be a building that large?"

Wenren Tutu was a bit bewildered.

One must know, the mountain directly in front of them was over a thousand meters high and seven to eight kilometers wide.

The two mountains on the left and right were even more absurd.

They were roughly the same height, but their width, which was equivalent to the depth of the valley, was over ten kilometers.

What kind of building could be built that big?

"You can't be sure; isn't Saudi Arabia building THE LINE, a super city over two hundred kilometers long?"

At this moment, Lin Changyun, who was nearby, quickly said.

"I still think it's a bit far-fetched."

Wenren Tutu shook her head. If they really were three gigantic buildings like that, it would be too preposterous!

To build something so massive, relying purely on backward human labor, would be impossible to complete in less than several decades.

"Forget whether it's preposterous or not; everyone, let's continue attacking this barrier. I refuse to believe we can't break it."

Guo Feng also found it preposterous.

However, this was his only option.

After all, he had to speed up, otherwise, if Academician Zhou and his crew outside were completely annihilated—firstly, the nation would suffer too great a loss; secondly, he would lose all face.

Of course, the former was more important.

Thus, he led the crew, continuously attacking the barrier.

Especially him, with his powerful and heavy strikes, each slash caused the three great mountains to constantly vibrate.

The surrounding rocks began to crack, as if they were about to collapse.

Afterward, Li Yanhua proposed an idea: if these three great mountains were buildings, and the rocks attached to them were merely camouflage, and the barrier could vibrate these rocks, then the effect would be better if everyone attacked at a consistent frequency.

The crew all thought this method was effective.

So, they had one person call out a rhythm, and everyone attacked the barrier with full force simultaneously.

Indeed, with everyone's frequency consistent, wave after wave of attacks followed.

The speed at which the rocks collapsed increased significantly.

"Look, it's a building!"

After they had continuously attacked over a hundred times, someone saw the outline of a building through the collapsing rocks!

"Holy cow, it really is a building?!"

At this, even Guo Feng was astonished.

Three colossal buildings, over a thousand meters high, several kilometers wide, and over ten kilometers long?

What were they used for?

And why were they sealed by rocks, yet still had plants growing on them?

He immediately shouted, "Everyone, keep going! Shake these rocks off completely!"

Subsequently, the crew, unafraid of exhaustion, continuously attacked the barrier with full force at the same frequency.

Deafening roars echoed ceaselessly throughout the entire valley, like endless thunder.

And the earth and rocks attached to the three colossal buildings began to crack uncontrollably, falling and collapsing with acceleration.

It was very much like tearing off calluses from a person's body.

Just as the crew were drenched in sweat from exhaustion, three incredibly majestic buildings were completely revealed before them!

This was! Square, incredibly massive, even gleaming with a metallic luster, and aesthetically somewhat conforming to modern tastes!

At a glance, it seemed that every hundred meters there was a metal statue, twenty to thirty meters tall.

They varied in form and facial features, looking somewhat exotic.

And some parts of this so-called 'valley' also revealed their true appearance, which was some kind of metal plaza.

It was as if these buildings, sealed for an unknown number of years, had reappeared in the world.

"Wow, this is too shocking!"

"This isn't a building; it should be a city!"

"What kind of metal is this? How does it look like there's no trace of corrosion at all?"

The crew were also stunned.

They felt as if they were having a temporal encounter with ancient spirit realm creatures from tens of thousands of years ago.

"A city?"

"A metal city?"

"Completely different from sect ruins."

"Could it be that this is where ordinary people lived in the ancient spirit realm?"

Guo Feng's heart was also extremely shaken.

How could he have imagined that this so-called 'valley' was such a magnificent city?

"Tang Xiaoyao, Lin Changyun, Shao Jingting, Zhao Long, Li Yanhua, Wenren Tutu, Guo Dagang, the six of you, each lead a team and briefly explore the left and right buildings in your respective areas."

"If you find anything concerning the barrier, report back immediately."

"I will explore the building in the very center alone."

"Our primary mission is to open the barrier and go out to rescue Academician Zhou and his crew!"

"Do you understand?"

Guo Feng quickly recovered and immediately issued orders to the crew.

They were all powerhouses at Level 39 and Level 40.

Leading some other Genius Class members above Level 30 should not be a big problem.

"Yes!"

The crew immediately replied.

"In twenty minutes, no matter the situation, you must return here to gather. Safety first. Move out!"

After Guo Feng finished speaking, he shot towards the building in front like lightning.

This building was a thousand meters high and seven to eight kilometers wide.

He ascended to a thousand meters in the air and looked down.

The building's depth was also about one kilometer.

It was an extremely massive building, covering an area of seven to eight square kilometers, equivalent to eight million square meters or twelve thousand mu.

And its height was over a thousand meters; if calculated at five meters per floor, it would have two hundred stories.

The world's tallest Burj Khalifa is only over eight hundred meters tall, covering 340,000 square meters.

One can imagine the vast difference.

And this was a perfectly square building, with an unimaginable total construction area.

Guo Feng discovered a huge main entrance, flanked by two massive statues holding weapons.

He entered the main gate and arrived in an enormous hall, empty and permeated with a sense of decay.

It seemed that many things had long since vanished under the power of time, leaving only the building itself.

"There must be a place to control the barrier here."

"This barrier serves to protect and isolate from external intrusion. If it can be controlled, it would be convenient for Academician Zhou and his crew to survive here."

"And this kind of building should not be the only one."

"So, if we find existing city buildings, population migration will definitely be more convenient."

"Moreover, this barrier technology must be researched by Academician Zhou and his crew!"

"Where there are buildings, there is civilization, so ancient historians will have work again!"

Guo Feng couldn't help but exclaim as he searched inside.

He also realized that it was fortunate it was daytime and he was powerful; otherwise, in such an ancient and desolate giant building, he would probably be scared to death.

Finally, he found a room.

Here were several metal steles, covered with various symbols and array patterns that Guo Feng did not recognize.

"This must be it!"

Guo Feng hurried over, took a look, and was a bit bewildered, completely unsure how to operate it.

Clank, clank...

However, just as he approached the metal steles, heavy and eerie footsteps suddenly came from the shadows.

Then, he saw three puppets, similar to those in Tianqi Sect, lifelike, like Bionic Man (bionic humans).

"Bold intruders, die!"

"Trespassing into the Central Chamber, death!"

The three puppets roared, each wielding a combat saber, and fiercely slashed towards Guo Feng! Their momentum was fierce! They all had Level 70 strength!
