The calm all the way was a little excessive, but Song Rui had a feeling of crisis on the side, as if the trembling feeling that penetrated the bone marrow made Song Rui's nerves tense, if he had hair, he would definitely be in a state of cold hair standing on end now.

Zebra ignored Song Rui, he himself felt that way, but Zebra was so experienced, this residual momentum had no effect on him at all, and his calm appearance also gave Song Rui a lot of confidence.

In the final analysis, Song Rui still has too little experience in facing various situations, and it is no wonder that the environment in which he once lived rarely existed even a hidden murderer, and the most sinister situation was just that the mobile phone was stolen, and there was no way to clear the customs even after looking at it......

After coming to this world, although his strength has grown rapidly, his psychological endurance has not increased much in the face of danger. If a beast appeared in front of him, the fighting instinct flinched, and he probably didn't feel much psychological pressure. But now it is the oppressive feeling that the environment invisibly gives people, and it is gradually increasing, and the enemy can't see or touch, this feeling of depression and trembling gives people the greatest pressure, Song Rui feels very sensitive, so this pressure has a greater impact on him.

This feeling is like watching a horror movie, if a hideous monster suddenly appears in front of you, it may be nothing after a start, but if the environment, music, and atmosphere are brewing, the monster does not appear for a long time, which gives people more pressure.

Song Rui felt that he might indeed underestimate the danger of this underground palace, just saying that the sense of oppression brought by this periphery was not something that he could handle alone, and if Zebra was not there, the pressure on himself would undoubtedly be greater. Thinking of this, Song Rui was a little glad for Zebra's peers.

"This is the entrance to the dungeon." Zebra's muffled voice pulled Song Rui from his contemplation, "Wandering in this place, do you want to die, Robot?!" ”

"En......" Song Rui smiled, not caring about Zebra's unceremonious speech, and set his eyes on the huge stone gate in front of him.

Seeing this, Song Rui muttered in his heart, no matter how he looked at this stone gate, he had a very familiar feeling, but he couldn't catch this feeling for a while.

The stone gate is about 20 meters high, about 9 meters wide, it is open in two doors, it looks extremely heavy, there are some reliefs on it, the lines are rough but very rigorous, Song Rui carefully identifies it, it seems to be some animal and plant patterns on it, but it is not very clear.

Because of the age, even if the materials are strong, it is inevitable to oxidize and corrode, and the surface of the stone gate has been a little mottled, full of traces of time, and there is a thick layer of ice in some places.

"How do you get in?" Song Rui looked to both sides, but didn't find a raised button or anything like that, "Don't tell me I need to break into the door violently." ”

"......" Zebra walked to the right side of the passage and pressed on a piece of bluestone, and the stone slab turned over, revealing a dark grid with a disc inside.

Zebra spun the disc and heard a creaking sound, accompanied by a rumbling sound like a stone wheel rolling, and the door opened!

Song Rui couldn't help but sigh, this underground palace has a history of thousands of years, and the mechanism can still be used, and it has not been frozen by the ice, the wisdom and skills of the ancient people can be described as miraculous.

However, Song Rui guessed wrong this time, the skills of the ancients are indeed magical, but this has nothing to do with cold ice, there will be no ice in the underground palace, which Song Rui only discovered after entering.

Song Rui slipped behind Zebra and looked at the disc, it seemed to be a jade plate with reliefs, because there was ice everywhere, so there was not much dust on it, and the reliefs on it were clearly visible, and suddenly Song Rui's eyes froze, and he pressed Zebra's palm that planned to reset the slate.

"Zebra, what's this pattern?" Song Rui pointed to the relief on the disc.

Zebra glanced at the jade plate, "Who knows! ”

"Take a closer look." Song Rui's tone was very serious, "This is very important, have you ever seen this animal somewhere, or similar patterns, it may not be real, some fictional images can also be!" ”

Zebra took another closer look at the relief, "I don't know, I've never seen it." ”

Song Rui opened the gimbal he had prepared and took a picture of the relief on the jade plate.

Song Rui has seen this pattern, but he has not seen it in this world, but the original earth, and the relief on it Song Rui is also very familiar, it is the five-clawed dragon of Huaxia!

Dragons, mythical creatures in ancient myths and legends in East Asia such as Huaxia, are the length of scale insects. It is one of the most representative traditional cultures in China, and the legend of the dragon and the dragon culture are very rich.

The most basic feature of the image of the dragon is the 'nine likeness', that is, the Song people's Luo Yuan 'release the dragon': the horns are like a deer, the head is like a camel, the eyes are like a rabbit, the neck is like a snake, the belly is like a mirage, the scales are like a fish, the claws are like an eagle, the palm is like a tiger, and the ears are like a cow. It has eighty-one scales on its back, with nine or nine yang numbers. Later generations have continuously refined the image of Longde, and there are many kinds of sayings, which will not be repeated here.

Legend has it that dragons can be dark and bright, small and huge, short and long. The spring equinox ascends to the sky, and the autumn equinox dives into the abyss, calling for wind and rain.

Song Rui noticed that the relief of this dragon did not have wings, and the idea that the pterosaur was respected and true originally appeared in the Western Zhou Dynasty, and the image of the pterosaur was the most common in the ornamental vessels of the pre-Qin dynasty of the Western Zhou Dynasty, but it is not certain that this image came from before the Western Zhou Dynasty, and it may not even have anything to do with these two dynasties.

There are countless legends about dragons, but these are just creatures from ancient folklore and legends, which cannot be found in reality, and the composition of their images is derived from reality.

The image of the Huaxia dragon is generally said to be derived from the Yellow Emperor's 'Busan Hefu', and the other theory is the fictitious image of the ancient ancestors.

The cultivation of a culture requires a strong historical background, and there are many coincidences, that is, on the original earth, the legend of the dragon was limited to Southeast Asia, and it was the most prevalent in China. Although Song Rui has been here for a short time, he is 100% sure that he has never seen the image of a dragon in this world! Moreover, Song Rui read the history of this world, and did not think that the culture of Shenlong would be produced in such an environment.

Then the significance of this relief is not trivial! Song Rui trembled a little excitedly, and several speculations instantly appeared in his heart, but no matter which speculation it was, it was enough to make him excited.

Song Rui's excitement, Zebra naturally saw it, although he was puzzled, he didn't bother Song Rui out of the voice, but waited for him to come back to his senses.

Song Rui's hands trembled a little, he scolded himself secretly, took out a 3D scanner from his backpack, scanned every detail of this disc in it, and then put it away, only then did he breathe a sigh of relief.

When he came back to his senses, Song Rui coughed dryly, a little surprised.

At this moment, a sudden change occurred!
