Chapter 115 Concrete Vault Building
Chen Fan subconsciously turned around and cast his eyes in the direction of the cathedral.
The lush Forest of Sighs blocked most of the view, and only the light of the towering molten salt tower power station was still shining.
He turned his head, nodded to Holt, and whispered: "Thank the Pope for me."
After that, he walked towards the metal gate in front without hesitation.
The passage formed by the heavy city gate is very dry, which is obviously different from the forest environment with a bit of moisture outside.
Chen Fan turned his head and looked around. There are a lot of tooth-like structures and tiny holes in the wall of the passage, that is, the place where the city gate is embedded.
A slight hissing sound came from these tiny holes.
[Nitrogen. ]
The voice of the smart terminal sounded in Chen Fan's mind: [These small holes are releasing nitrogen outward, which should be a byproduct of the plasma barrier. 】
【When the gate was closed, these tooth structures matched each other to form a relatively closed space, and these dry nitrogen could exclude all the oxygen and water vapor from the outside, thereby slowing down the oxidation of the internal structure of the gate. 】
At the same time, Chen Fan's mind appeared the scanned image provided by Yi.
Looking at the various precision machines inside the city wall, Chen Fan couldn't help but exclaimed in his heart.
...
The rumbling sound came from behind again.
The heavy metal door opened for less than five minutes and then closed again, and the path connecting the inside and outside of the city disappeared.
Chen Fan casually looked at the surrounding vegetation and retracted his gaze with a calm expression.
Isa and Gao Yuan, who followed him, obviously couldn't be so calm.
Since they were born, this is the first time they have stepped on the land outside the city of Varela.
Feeling the extremely soft soil under his feet, Gao Yuan's face was full of excitement, and for a moment he didn't even know which foot to take.
Isa's reaction was similar.
She squatted down, letting her black priest robes drape over the wet and muddy ground, then stretched out her mechanical prosthesis and gently poked the soft and wet soil.
Looking at the scene in front of him, Chen Fan laughed dumbly.
He did not interrupt the "immersive experience" of the two.
"One, release the micro-detection drone."
Chen Fan clenched his right hand and gave an order to One.
A fluorescent green light flashed, and the spherical detection drone quickly appeared in Chen Fan's palm.
He loosened his right hand, and the drone quickly took off, drew a graceful arc and disappeared from sight.
Bang!
With a not-so-loud explosion coming from the sky, Isa and Gao Yuan subconsciously raised their heads and cast confused eyes at Chen Fan.
Chen Fan waved his hands: "Nothing."
"It's just the sonic boom made by the drone when it broke the speed of sound."
As the voice fell, a deep blue holographic projection automatically appeared beside him.
The projection clearly showed the shooting pictures from the drone.
The lush forest stretched out in all directions, as if there was no end.
As the drone moved faster and faster, the forest gradually became sparser.
Suddenly,
the high-speed drone hovered in the air.
From extreme movement to extreme stillness, there was almost no deceleration in between!
In the center of the drone's lens, a building of a completely different style quietly crouched in the forest.
...
The huge, gray-white concrete arched vault crouched on the ground, hiding the details of the building well.
Against the backdrop of the lush green woods around it, this pale vaulted building looks like a boil growing on the ground, which looks extremely inconsistent.
Next to the vaulted building, a tall tower with a silvery-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 the antenna of something.
As the drone continues to descend, more details appear in the holographic panel in front of Chen Fan.
Although the ground around the vaulted building is covered with a lot of vegetation, it can still be seen that the vegetation near the building is obviously much thinner than the vegetation farther away.
Soon, when the drone descended again, Chen Fan found the reason -
there was no thick soil at the bottom of these vegetation, only a concrete base that was already full of cracks!
Some fine dust and moss are distributed on this base, which together constitute the growth environment of these vegetation.
In other words, a huge concrete dome was poured around this arc-shaped vaulted building!
A huge disc quickly emerged on the holographic projection beside him - this was the size of the entire concrete base.
As for the vaulted building, it was just a small protrusion in the center of the disc.
Looking at the strange shape in the holographic projection, Chen Fan couldn't help but have a guess in his mind:
The entire building...
wouldn't it be buried underground? !
As soon as this thought flashed through his mind, Yi's voice came: "This machine has analyzed the vegetation around the concrete dome."
"It is basically certain that the roots of the vegetation around the concrete dome have been affected to varying degrees."
"Their roots are growing outside the dome."
"It is basically certain that there are a lot of concrete structures under the dome."
Chen Fan, whose guess was confirmed, subconsciously took a breath of cold air.
The vaulted building photographed by the drone is just a drop in the ocean of the entire building protruding from the surface! !
"What kind of building is this..."
Isa's confused voice came from the side: "It looks... seems to be very different from the city of Varela?"
Chen Fan's heart moved.
Judging from the cracks on the concrete base, this building is estimated to have existed for more than a hundred years.
The city was not built by the intelligent machines, and 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, and said his guess.
"What ruins!"
Chen Fan interrupted Gao Yuan unhappily.
If the ruins were made of such poor quality concrete, it would probably fall apart in a short time.
Is it still the turn of the humans and intelligent machines in this world to pick up the leaks?
Don't be ridiculous!
Besides, would a civilization that masters antimatter really use reinforced concrete to cast buildings?
"This is obviously the remains of the building left by your ancestors!"
Gao Yuan laughed awkwardly and touched his nose awkwardly: "Then what should we do next..."
"Of course, we should go and see what is in the remains of the building."
As the voice fell, a winding curve that passed through the dense forest automatically emerged in the holographic projection beside Chen Fan -
this is the navigation route provided by Yi, which avoids a lot of difficult areas.
ps: Thanks to the leader of the [Tenth Art] boss for the reward!
The boss is awesome! ! !
It's over.
How come the amount of debts is increasing? (T＿T)
