The city that appears in the distance is of a very grand scale even when seen from a distance.
Just looking at it from where Karl and the others were, this was a city that could accommodate at least hundreds of thousands of people.
Compared to the underground environment, this is absolutely astonishing in scale.
Following the retreating blue Poseidon, Karl and the others were also approaching the city little by little.
About a kilometer away, they again noticed another very surprising thing.
Since entering this deep underground world, all the plants they have seen are basically fungi, that is, those unusually large mushrooms.
But when we got here, the city in front of us exceeded this concept.
No bricks, stones, or other building materials are used.
Just looking at the walls of this city, it turns out that it is a huge wooden wall that looks like a whole, with no connecting gaps!
No, to be more precise, this should be a severed tree root, and then someone dug out a city on this tree root.
Facing such a city, Karl couldn't help but murmured:
"Celile, have you ever seen such a big tree root?"
In the same way, Cyril also replied in an unbelievable tone:
"Believe me, even the World Tree created by the Nordic Gods is just a sapling in front of it..."
As a result, at this moment, Naiya spoke to break the shocked atmosphere between the two.
“But people can do it!”
"As long as I recover to full health, it won't be a problem to plant ten or eight saplings of this size in one day."
After glaring fiercely at Naia who suddenly disrupted the situation, Seril immediately replied:
"Ma'am, please make a draft before you brag!"
Looking at Cyril who didn’t believe in her abilities at all, the bright smile on Naia’s face gradually became abnormal:
"Hoo ho ho!"
"Today I want to let you see me as the Night Roarer, the God of Blood Tongue, the Black-haired Old Man, the Faceless God, the Night Hunter, the Swollen Daughter, the Messenger of the Old Gods, and the Dweller of Darkness, Nyarlatoti
It’s so awesome!”
bump!
Before Naia could do anything shocking, Karl punched her in the head.
"You can give me a little less work!"
"ah......"
"Ahhh!"
After being hit by Karl's punch, Naia immediately looked like she was in great pain, and rolled on the ground holding her head and wailing:
"My Evil God Radar!"
"Okay, let's keep walking."
Karl, who knew Naiya's character well, would not be fooled by such a reaction. He pulled Ceryl with him after saying a few words and continued to follow the blue Poseidon.
Only Green, who was at the back of the team, could not bear to care about Naia:
"Miss Naiya, are you okay?"
"Oh, I'm fine."
Seeing Karl who continued to move forward completely regardless of herself, Naiya stopped crying instantly, got up and chased after him as if nothing happened.
"Karl, please wait for me!"
"I have a short body and short legs, so I run slowly!"
Green, who was left on the spot, was dumbfounded for a while, then finally shook his head and followed.
Although Blue Poseidon's footsteps are not fast, they are better than steady.
In his methodical retreat, this underground city gradually appeared in front of Karl and the others.
First, directly opposite them, an arched city gate was embedded in the surface of the huge city wall.
Because the entire structure is made of wood mixed together, the entrance passage is like a large hole dug by craftsmen, with no trace of artificial construction like ordinary city gates.
But purely in terms of style, it looks quite handsome.
However, looking at the city in front of him, Karl pointed at the blue Poseidon and said:
"Naiya, can you please stop this thing for a while?"
"Of course no problem."
Almost at the same time Naia answered him, the blue Poseidon also stopped retreating.
The whole person stood still in place like a paused movie.
"Mr. Carl, what's going on?"
Catching up from behind, Green immediately raised his own doubts about Karl's choice.
"Is there something wrong with this city?"
"Of course."
This time, it was Cyril who answered Green's question.
"Look carefully, does this city look like a place where living people can live?"
After getting a tip from Cyril, Green realized a very shocking fact.
As they walked to the gate of the city, a large amount of dust appeared on the ground around them, and the scattered footprints on it were all from the city gate.
In the entire surrounding sight, only a few of their footprints were heading towards the interior of the city!
How can a city that is functioning normally and has people living in it be in such a state of failure?
Not to mention that this kind of thick dust shouldn't be in a place like this.
After looking at Karl, who had a solemn look on his face, Selil immediately added:
"The underground race I saw in Poseidon's memory is not a weird thing. They are a kind of life similar to humans. It is completely impossible to live in this kind of city."
Saying this, Seliel squatted on the ground and wiped away a thick layer of dust with her hands.
"Judging from the dust in this place, this city has been here peacefully for at least hundreds of years."
However, almost as soon as Cyril opened her mouth, Naia lay on the ground without any care, then stuck out her tongue and licked the dust on the ground.
Bliss
"Bah, bah, bah..."
Judging from this guy's expression and reaction, the dust here is definitely not delicious.
While wiping his tongue, Naiya also said:
"You may not believe it, but the wood under our feet is already 1.7 billion years old."
"How is this possible!"
This time, it was Karl who exclaimed.
Based on his knowledge before time travel, 1.7 billion years ago, the earth was still in the Proterozoic Eon.
That was an unobservable era long before the development of life on earth.
It is unbelievable that such a huge tree appeared at that time and maintained its state until today!
Regardless of the development of life or the evolution history of the earth itself, this is something that Karl absolutely cannot accept.
At the same time, Cyril, who was crazy about absorbing modern knowledge, also understood the meaning of this sentence, so now she looked at Naia with a serious face and said:
"Don't joke with us."
"I have no interest in lying to you here."
Rolling his eyes helplessly, Naia then continued:
"The texture of this wood is also full of strange feelings. Even if my complete body comes, it may not be an easy thing to toss it out."
Listening to Naiya's description, Karl suppressed the uneasiness in his heart.
Since this evil god has said so, why not give it a try yourself.
Karl immediately took out the [Decapitating Blade], pointed it at the wood on the ground, and chopped it.
