There are lines outlined on the wall, which are not particularly complicated, but are completely different from any Array that Human Race currently has.
At least there is no energy core source on this line.
In other words, its startup does not depend on items like Demon Crystal.
"Imprinted on Cave Entrance, and only for the Demon Clan."
Yu Sheng thought for a few seconds, took out his phone, and took pictures of the textures on the wall.
Worried that it was just a simple photo, it might not be able to restore the core of Array, so Yu Sheng evenly applied ink on the wall, pasted a piece of white paper, and completely copied it.
The internal space of Mountains and Rivers Bottle had become empty after the previous burning. Yu Sheng spent a whole day shopping in the department store before replenishing the equipment.
Putting away the white paper, Yu Sheng turned around and looked inside Mountain Cave.
"I just said that it is unreasonable to have a buffer but not Mountain Cave."
"It should be the movement of the earth's crust, or the passage of time, that has obscured Cave Entrance..."
Yu Sheng whispered softly.
Mountain Cave itself is not that big. There is only a narrow passage leading to the depths, and the environment is a bit dry.
"According to common sense, Mountain Cave has not been exposed to sunlight all year round, so it should be humid."
"Is it because Mountain Cave is used for living, so what measures have been taken to prevent moisture?"
With doubts, Yu Sheng kept walking inside.
But the passage seems extremely long and slightly sloping, as if it is constantly walking towards the belly of the mountain.
As it goes deeper, the walls on both sides become smoother and smoother, and there are obviously some artificial traces.
Yu Sheng's pace gradually slowed down, holding Long Sword in his hand, and walked forward slowly.
Mountain Cave seems to be extremely profound, with no end in sight. Even the Giant Flashlight on the shoulder cannot shine through.
In the silent passage, only the footsteps of Yu Sheng continued to echo.
The atmosphere became increasingly depressing.
After walking for about ten minutes in Mountain Cave, Yu Sheng stopped and looked at a stone wall in front of him, as if he had discovered something. He quickened his pace and walked over.
On the smooth stone wall, someone used a sharp tool to outline patterns, like a comic strip.
The first one...
A bustling scene, many antique buildings, and an endless stream of people on the streets!
It's just that in this scene, there is no technology, including high-rise buildings, buildings, cars, etc., and it looks very primitive.
But...
A Child is holding a Leopard in his hand. The Leopard looks very well-behaved, lying on the ground and letting Child stroke its forehead.
In terms of body size, Demon Domain is at least the level of Third Level.
Not far away, a man wearing ordinary Middle-Aged Man was riding on the back of a Fierce Tiger. The Fierce Tiger also had cloth bags hanging around its waist, which seemed to be full of goods.
That huge body, Fifth Level starts!
And this scene seems to be seen everywhere on the streets, just like before Spirit Energy Revival, people were walking dogs, raising cats, and riding horses.
It's just that their pets look a bit... fierce!
The tallest building in Image is a three-story wooden building.
On the terrace outside the third floor, there is a Young Man standing. Although it is just a few simple strokes, it still highlights the aloof temperament of Young Man, which is obviously different from everyone on the street.
Young Man put his hands behind his back and looked down at the street. A piece of Long Gown was swaying in the wind, and his long hair was also blown a little by the wind.
The style of the second mural begins to reveal a little bit of Fighting Spirit.
Young Man seems to have grown a little bit into Middle-Aged Man.
His temperament is restrained and does not show off his edge.
He stood on a City, City depicted Plaque, but Yu Sheng did not recognize the words on it.
Inside City, the people looked a little nervous, but when they looked at the back of Middle-Aged Man, there was a look of trust in their eyes.
Besides City, there are also countless people.
These people are all riding on top of Demon Beast, holding weapons, as if they want to attack City.
The third mural.
City looked a little dilapidated, but in the end he managed to hold on. Middle-Aged Man sat alone on the top of the city. Long Gown was still swaying in the wind, but his long hair was spread down and draped casually on his shoulders.
He held a wine bottle in his hand and took a swig!
Below, there are densely packed corpses, both human and animal...
The people in City are rebuilding their homes.
Although it looks a bit miserable, Image highlights a sense of warmth.
Yu Sheng did not look back in a hurry, but took out his mobile phone, pointed at the murals, recorded them, and carefully analyzed the details revealed in the murals.
First of all, there was no such thing as Demon Clan in the era shown in the mural.
Those so-called powerful Demon Beast are just slaves of 'humans', used as pets, transportation tools, or tools of war.
Of course, although these existences that rule Demon Clan look exactly the same as humans, they may also have unique names for themselves.
So the word 'human' is in quotation marks.
Moreover, it can be analyzed through the murals that they did not study technology, but purely followed the path of spiritual practice, and their overall spiritual strength was not weak.
At least I want a Tiger from Fifth Level to carry the goods for me honestly. Without absolute strength, it is difficult to do so.
But this is just a random Middle-Aged Man walking on the street.
It's hard to imagine how powerful 'human beings' were in that era, or what the world outside City was like.
Judging from the three murals currently known, they are already full of shock.
