The emperor lived up to his wishes, and after most of the day's tossing, the door in front of Li Yong finally opened slowly, showing the dark underground passage inside in front of His Royal Highness the Demon King.

"Whew...... Hmph, that's it. ”

After passing the test of this "face of truth", Lion took a deep breath and wanted to put on an expression of "I haven't used my strength, you have fallen" to pretend, but the tightly held "communication board" in his hand exposed this guy's embarrassment.

Although he has received the "cramming education" of Teacher Aurora, it is of course a bit difficult to make a fool become a master of puzzle solving in a short period of time.

As a result, Lyon was also thrilling in this breakthrough, and finally relied on Aurora's "off-site assistance" to successfully break through.

What's in it? What is it?

Rion bent over through the narrow passages, and because he could see in the dark, he was able to walk without any stress even in the narrow dark passages.

It is said that this is an underground library that has existed since the establishment of "Eternal Winter City", and it seems that it has not been damaged even on the days of several previous breaches, so it must be a very old storage room or something.

As he walked, Rion thought about the origin of this "underground library", after all, no one could enter this place except for the demon kings and auxiliary ministers of each generation, so there was very little information about this place.

As he progressed, Rion felt as if he was constantly walking down the stairs towards the "underground", the spiral passages as if to bring people into the center of the earth, and the various lines on the surrounding passages became more and more like incantations representing certain meanings.

Before he knew it, he didn't know how long he had been walking, but the deeper he went, the more dreary the rotting air became.

"Whew...... Is it so deep, at least a quarter of an hour's walk?" Lion sighed, not understanding why this passage was built so underneath.

However, just when Lyon couldn't hold back and was about to rush down at a faster speed, a little light appeared at the end of the passage.

Is there light? Is there light? This ...... After seeing this scene, Liyong was stunned for a moment, because as far as he knew, no one had come to this place for a long time, so what was the obvious firelight?

When I walked in, I saw that the faint light came from the crack in the door at the end of the passage, and now the door was half-closed, and it seemed that there was a mystery inside.

However, when Lion pushed the door in, the scene inside made him stunned for a moment, not that there was anything surprising inside, but that the "underground library" he saw was too ...... Feeling familiar?

This huge underground room is designed in a circle, the whole room layout is like a huge cylinder, and there are rows of bookshelves around the room, and these bookshelves are stacked on the 100-meter-high ceiling as if they are building a house, and they are densely packed with books I don't know how many books are placed......

"Wait, isn't this almost exactly the same as Aurora's Big Library?"

Before coming to this "underground library", Lion didn't know how many times he had imagined the situation inside, but what he didn't expect was that the layout and furnishings of this place were almost exactly the same as the "big library" in the "Kabbalah Temple"!

Books, books, books! Countless books were densely packed in the huge room, surrounded by several seemingly unquenchable torches, providing bright light to the huge room.

"It still looks spectacular, isn't it the same person here as the designer of the Kabbalah Temple?"

Despite these doubts, Rion quickly looked around to see if there were any documents like the "Solomon Manuscripts" that could provide many clues.

Having spent many days in the "Great Library", Rion was also very familiar with this "underground library", and quickly walked around, but did not find any handmade documents like the "Solomonic Manuscript", and a large number of books were obviously printed.

Wait, this place seems to be a bit different from the "Big Library", what is it?

When Lyon walked to the innermost bookshelf, he suddenly found that the innermost bookshelf was completely different from the one in the "Great Library".

Originally, the bookshelf in the "big library" was placed vertically, and you could see a little wall behind it, but here it was horizontally, covering the wall behind it.

This feeling...... Ah, if there is another passage at the head, I am such a clever little ghost.

After casually removing the bookshelf, another passage appeared in front of Rion, and after a shameless praise of himself, he walked inside.

The passage is quite short, and it takes a few steps to the basement inside, and in the deepest part of this basement, in front of Rion is an altar that exudes a sense of history.

At the end of the altar is a large "stone slab", and three smaller stone slabs are displayed in a triangle in front of the huge stone slab, which is all the contents of this basement.

"What is this, one large, three small, four slates?"

After a moment's hesitation, Rion cautiously walked up to the altar and took a closer look at the three small stone tablets placed in front of him, the front and back of which were engraved with patterns and texts that looked similar to those on the "Manuscripts of Solomon", which were supposed to be very ancient.

The front of the first slab is engraved with the image of a "huge amorphous mass of tentacles, constantly wriggling in the dark, covered in tentacles, giving a sense of turbidity", and behind it is engraved in ancient script: "Azathoth, the core of the primordial chaos".

The front of the second slab is engraved with an image of "many tentacles resembling an octopus, which looks like a black goat from a distance", and on the back is the words "The Most High Mother Goddess - Shabu Nicholas" is engraved in ancient characters.

The front of the third stone tablet is engraved with the image of a "humanoid shadow floating on a megalithic throne in the universe", and on the back is the words "The primeval Eternal-Tavir Yat Umr" is engraved in ancient script.

When the core of the primordial chaos was seen, the Supreme Mother Goddess, the primeval eternal, and the whole picture of these three stone tablets, for some reason, Lion suddenly felt an inexplicable pressure, as if there were many monsters in the darkness watching him.

"These three images and names...... This is the legendary ......."

After taking a few steps back to stabilize his mind, a legend he had heard before appeared in Rion's mind. 2k reading web
