We should not forget history, just as we have created history that needs to be remembered by future generations.

In the mural that walks forward, there is a scene depicting a group of masked men, dancing after the masked man in front. The man in the front is strong, jumps in the air, and wears a mask without a pattern. This is the scene of the ghost slave people following the ghost slave king, and the relief in it is the ghost slave king. Their masks are distinctive, they are all hateful-looking demons, which are diametrically opposed to those worn by Nannu, because the style of the paintings is very strange, and even described as evil. The ghost slave king's face is not so much a mask, but the facial features disappear. Their dance moves are particularly bizarre, with their hands and feet bent at angles that are difficult to achieve, revealing infinite horror when paired with their masks.

It seems that the ghost slave clan is a people with a long history, which is reflected in ancient murals.

The Ghost Slave King and the Nian Slave were naturally fascinated by this mural and were fascinated by the joyful scenes of the ancients. Especially Nian Nu, he couldn't help but lean on the ghost slave king, touching his face with his hand from time to time, and later found that he had no mask anymore, and he couldn't help but be disappointed.

The ghost slave king knew what Nian Nu was thinking, and persuaded her: "The matter has come to this point, don't worry about it." The mask is just a formality, as long as you want to be a ghost slave, you can follow me forever. ”

Nian Nu bowed his head in embarrassment and was silent, his face flushed. In order to prevent them from touching the scene, Guanglong hurriedly broke them away.

The arrogance who was walking in front suddenly stopped everyone: "Come and see this painting, it's very familiar." "What did he find?

I saw a pyramid-shaped mountain on the picture, and the whole was in relief. The mountain is divided into 6 layers, and the area grows larger the further down it goes, but it is a hellish scene. The pool of blood, the burning, the iron tree, the mountain of knives, the extreme cold, and the layers of hell are vivid. At the bottom of the mountain, there are two circles of light, and I don't know what the purpose is.

Paintings are often more terrifying than reality, with corpses floating in pools of blood, skeletons of people in the burning flames, bones of people hanging on iron trees, people crawling on the Knife Mountain covered in bloody holes, people who can't be relied on on in the extremely cold earth fighting corpses in the wilderness, and people killing each other in despair. This is the real hell.

The Ghost Slave King pointed to the aperture below, saying that it was very similar to the space and time layer of the Infernal Hell, and it turned out that it was at the lowest level at the beginning.

Guanglong explained to everyone that in his world, there are eighteen layers of hell, which does not refer to the relationship between the upper and lower structures, but in the sense of space and time. If the mural depicts the original map of Infernal Hell, it is likely that the spatial and temporal layers below are the centers that control the workings of Hell, especially directly affecting Infernal Hell.

The mural depicts a little different from reality, except for the time and space at the bottom, the depth of the iron tree in reality is incomparable to the mural.

Changfeng analyzed that hell should be designed according to the map, and the reason why Infernal Hell and time and space are at the same level is because of the overall subsidence.

Guanglong only reacted, the underground can be empty for a large ~ piece, and it is not a fantasy for the Infernal Hell to be one, so the explanation is reasonable.

Why is the Netherworld Underground Prison modeled after a mural? Guanglong deduced that in the process of excavating the deadly rough stone, he broke through the passage of the underground city agglomeration and accidentally discovered the ancient hell picture. When the rough stone was abandoned and no longer excavated, the pit was filled in and the hell in the picture was built on the pathway. At that time, the ten emperors must have known about the underground civilization, and perhaps they were afraid of the impact on their own country and did not dare to announce it to the outside world, so they hid their former glory.

As the dust falls, the original stone and the ruins of the underground city disappear into history. This has also become an untold secret among the ten emperors.

Arrogant said that without the effect of underground rough stones, even if there is time and space, it will not work. It is the original stone that makes hell, and it is destined in the dark.

Guanglong had a bold idea, what the Netherworld wanted to cover up was not the original stones, if they really regarded them as evil, why did they still use them on the Soul Express. What the Netherworld really wants to cover is an underground city beyond its own civilization, which contains black technology that challenges cognition and is capable of subverting the rule of the Empire. In order to maintain the ignorance of his country, Netherworld ordered the dust to be sealed underground, and also used technology to strengthen the defense function of the Infernal Hell so that others would not find out.

Why is the whereabouts of the original prison warden Long Baiying unknown? The current prison guards are only guarding the first floor, so why don't they dare to go down without permission? There is also the Dusty Land, the scapegoat of the Wheel King, what crime is replaced. All the questions point to the same place: the ruins of the underground city.

The Wheel King nervously came down in person to stop them from advancing, which could confirm Guanglong's guess. He couldn't help but glance back at Changfeng, hoping that the secret buried deep underground had nothing to do with Changfeng.

When Guanglong was still conjecturing for no reason, Niannu had already looked up at the sky and counted the few stars.

Alas, the buildings built are all anticlimactic, and even the roofs have been forgotten. No, it's underground, how can there be a sky and stars. Guanglong looked up suddenly, and there were a few bits of light in the dark sky, not what the stars were.

Nian Nu was restrained and shy, but in fact, after she looked up, others had no eye contact with her, and she would not be so scared that she panicked. She is now an innocent little girl, and she says to herself: "The stars are so obedient, they will light up when they clap their hands." ”

Guanglong couldn't imagine that the stars were still voice-controlled, waiting for Niannu to perform. Nian Nu clapped his hands happily, and saw the black curtain above his head lit up with stars one after another.

Changfeng and the Ghost Slave King clapped their hands and stomped their feet, and the stars above lit up more. It is believed that it will not be long before the entire dome will shine brightly.

At first, Guanglong thought that there were insects such as fireflies on the top, or glowing microorganisms in the bitter sea, which glowed after being frightened. Later he realized that no, the stars were arranged irregularly and did not occupy the entire ceiling.

They didn't stop clapping until no new stars lit up. The sky full of stars above me really has the illusion of being in the vast stars. They reflexively sat on the ground, looking up at the mysterious starry sky.

Did the ancient Netherworld really have this kind of wisdom? Can create an original voice control system, what is the principle of the "star" that lights up.

Arrogantly said that what they were looking at was an ancient astrological chart, which was the crystallization of the wisdom of the ancients in studying astronomy. He also pointed out the constellations in the sky and identified the directions.

Guanglong knew very little about the constellations, and could only vaguely recognize the constellation Ursa Major, the Big Dipper. You must know that in ancient times, people knew more about astronomy than they imagined, but it was rare to be able to allude to the all-round three-dimensional astrological charts. In particular, the Netherworld, which does not pay attention to technology, is even more shocking.

The light of the stars was enough to illuminate the room, and the murals on either side dimmed. The meeting room doubles as a room for art exhibitions, and the design is exquisite. When you are quietly immersed in the artistic conception of the murals, you will dominate the artistic style; And when you make a loud noise, there is an expression of "disrespectful" art, and the room becomes a planetarium, eclipsing the mural. Although the mural can still be seen, it is invisibly lacking in taste.

The rest of the murals have a lot of black technology depicting the ancients: turning stones into alchemy, using "spells" to make gold, which is how the gold bricks outside the temple came from; Ancient electric lamps, filled with liquid in a container, with a wire inserted in the middle, and the other end of the wire is connected to an object in the shape of a bronze cup, shining; The human body is suspended, similar to modern magic shows, without the help of any tools to lift the feet off the ground; Head swap surgery, an angel flies in the air, but the head is a devil. The "doctor" standing below carries the head of a bloody angel. There are also a lot of cross-species hybridizations, fire-breathing robots, warships flying in the sky, and so on.

Guanglong felt a chill down his spine, the content on the mural was imagined out of thin air, or was there really a shocking technology at that time. The reason why the Netherworld is locked down here is because it is afraid that the ancient black technology will see the light of day?

They had no time to marvel at the wisdom and imagination of the ancients, and the priority was to find the Primordial Jade Vein and the Spades Man.

Walk through the meeting room and enter the main hall of the temple. The square hall is supported by eight giant pillars, and four birdcages hang from the roof, so that they can't see what is locked up from their angle. The main hall is flanked by streamer bronze mirrors that reflect light to illuminate the entire room. Opposite them was a throne or bed, on which lay a man.

The giant pillar is carved, and there are obscure hieroglyphs on it, like a book from the sky. The pillars are nothing special except for exquisiteness.

Guanglong walked directly to the throne, was the lying person dead or alive?
