With the support of a ninth-level civilization, do you want me to believe in electronic gods?

Chapter 115 Concrete Vault Construction

Chen Fan subconsciously turned around and cast his gaze in the direction of the main church.

The lush Forest of Sighs blocked most of the sight, and only the light of the towering molten salt tower power station still shone.

He turned back, nodded to Holt, and said softly: "Thank you to the Pope for me."

After saying that, he didn't hesitate and walked directly towards the metal door in front.

The passage formed by the thick city gate is very dry, which is obviously different from the forest environment with a bit of moisture outside.

Chen Fan turned around and looked around. There were a large number of tooth-like structures and tiny holes on the walls of the passage, where the city gates fit together.

A slight hissing sound comes from these tiny holes.

【Nitrogen. 】

The voice of the smart terminal sounded in Chen Fan's mind: [These small holes are releasing nitrogen, which should be a by-product of the plasma barrier. 】

[When the city gate is closed, these tooth-like structures match each other to form a relatively airtight space, and these dry nitrogen gases can exclude all oxygen and water vapor from the outside, thereby slowing down the oxidation of the internal structure of the city gate. 】

At the same time, the scanned image provided by Yi appeared in Chen Fan's mind.

Looking at the various precision machines inside the city wall, Chen Fan couldn't help but admire in his heart.

……

The rumble came from behind again.

The heavy metal gate was open for less than five minutes before closing again, and the path connecting the inside and outside of the city disappeared.

Chen Fan casually looked at the surrounding vegetation and then looked away with an indifferent expression.

Isha and Gao Yuan who were following him obviously couldn't be so calm.

This was the first time the two of them had set foot on land outside Varela City since they were born.

Feeling the extra soft soil under his feet, Gao Yuan's face was filled with excitement, and he didn't even know which foot to take for a while.

Issa's reaction was similar.

She knelt down and let the black sacrificial robe spread on the damp and muddy ground. Then she stretched out her mechanical prosthetic leg and gently poked the soft and damp soil.

Looking at the scene in front of him, Chen Fan burst into laughter.

He did not interrupt the "immersive experience" of the two.

"One, release the micro-detection drone."

Chen Fan held his right hand empty and gave an order to Yi.

A flash of fluorescent green light flashed, and the spherical detection drone quickly appeared in Chen Fan's palm.

As soon as he released his right hand, the drone quickly took off into the air, drew a beautiful arc and then disappeared from sight.

Bang!
As an insignificant explosion sounded from the sky, Isha and Gao Yuan subconsciously raised their heads and cast confused glances at Chen Fan.

Chen Fan waved his hand: "It's nothing."

"It's just the sonic boom the drone makes when it breaks the speed of sound."

As he finished speaking, a blue holographic projection automatically appeared beside him.

The projection clearly shows the footage from the drone.

The lush forest extends in all directions, as if there is no end.

As the drone moved faster and faster, the forest gradually became sparse.

suddenly.

The extremely fast flying drone instantly hovered in mid-air.

From extreme movement to extreme stillness, there is almost no deceleration in between!
In the center of the drone lens, a building with a different style is quietly crawling in the forest.

……

The huge, gray-white concrete curved vault lies above the ground, hiding the details of the building well. Against the backdrop of the surrounding green woods, the pale vaulted building looked like a pustule growing on the ground, looking extremely incongruous.

Next to the vaulted building, a tall tower with silver-white metallic luster stands on the ground.

Around the tower, there are dozens of straight and thick metal poles.

Each metal pole is spaced at a fixed distance and looks like an antenna for something.

As the height of the drone continued to decrease, more details were presented in the holographic panel in front of Chen Fan.

Although the ground around the vaulted building is covered with a large amount of vegetation, it can still be seen that compared with the vegetation further away, the vegetation near the building is obviously much thinner.

Soon, when the height of the drone dropped again, Chen Fan found the reason——

There is no thick soil at the bottom of these vegetations, only concrete bases that are already full of cracks!
Some fine dust and moss are distributed on this base, which together form the growth environment of these vegetations.

In other words, a huge concrete round platform was poured around this arc-vaulted building!
A huge disk quickly appeared on the holographic projection beside him - this was the size of the entire concrete base.

As for the vault building, it is just a small protrusion in the central area of ​​the disk.

Looking at the strange shapes in the holographic projection, Chen Fan couldn't help but have a guess in his mind:
The building as a whole…

Aren't they all buried underground? !

As soon as this thought flashed through my mind, a voice came: "This machine analyzed the vegetation around the concrete round platform."

"It is basically certain that the root systems of vegetation around the concrete circular platform have been affected to varying degrees."

"Their root systems all grow outside the circular cone."

"It is basically certain that there is a large amount of concrete structure under the circular platform."

Chen Fan took a deep breath subconsciously when his suspicion was confirmed.

The vaulted building captured by the drone is just a drop in the ocean of the entire building protruding from the ground! !

"What kind of building is this..."

Isa's confused voice came from beside her: "It seems... it seems to be very different from Varela City?"

Chen Fan's heart moved.

Judging from the cracks on the concrete base, the building is estimated to have existed for more than a hundred years.

A city not built by omnics, most of its volume is hidden under the ground...

Could it be that……

"Is this the ruins?"

Gao Yuan raised his hand and scratched his head, expressing his suspicion.

"The size of the ruins!"

Chen Fan interrupted Gao Yuan's words angrily.

If the ruins were made of such poor quality concrete, it would probably fall apart within a short time of preservation.

Is it the turn of humans and omnics in this world to pick things up?

Do not make jokes!
Besides, would a civilization that mastered antimatter really use reinforced concrete to build buildings?
"This looks like the remains of the building left by your ancestors!"

Gao Yuan sneered and touched the tip of his nose awkwardly: "Then let's do it next..."

"Of course we're going to see what's in the ruins of the building."

As he finished speaking, a winding curve running through the dense forest automatically appeared in the holographic projection beside Chen Fan——

This is a navigation route provided by Yi, which avoids a large number of difficult-to-reach areas.

ps: Thank you to the leader of [Tenth Art] for the reward!

The boss is awesome! ! !
It’s over.

Why do we owe so much more and more (T_T)
