Xiang Nan's heartbeat began to speed up, that black book was exactly the same as the black book that Xiao Que had stolen back.
It is even very possible that the black book in his ring and the one on the mural are the same one.
But what is this black book used for and what is its specific origin, there is no description on the mural.
It's just that on this picture of everyone holding up the black book, there are some patterns of unknown meaning, but which give people a strong sense of anxiety.
"This is an ominous sign." Big Snake said, "From these murals, we can probably see that what is recorded in this black book is a very dangerous thing."
"What it records is probably not a good thing."
Xiang Nan also felt this way.
There is a lot of space in this mountain, and there are many murals.
In order to clarify this problem, Xiang Nan accelerated his flight speed and flew around the interior of the mountain to see the huge and magnificent mural stories.
He found that most of these murals described the specific battle with the lightning bull.
However, there are very few records about the black book.
After Xiang Nan finished reading it, he could only be sure of one clue, that is, this black book did not belong to this extinct civilization.
Like Xiang Nan, they got the black book by accident and successfully opened it once.
But how to open it, what is the whole content inside, there is no relevant description on the mural.
However, another picture caught Xiang Nan's attention. What was depicted in this picture had nothing to do with the Black Book, or even the giant lightning bull.
Instead, it described another creature that Xiang Nan was already familiar with, the creature against the law.
From this mural, Xiang Nan saw an amazing fact. It turns out that the anti-law creatures in the Netherworld were originally "raised" by this lost civilization.
For the warriors of the lost civilization, anti-law creatures are also extremely scary and dangerous things. They are also carefully raised, and often they will be swallowed by anti-law creatures.
After the end of the war of annihilation, before all the human beings in this civilization perish, the only creatures against the law were released.
As for how the anti-law creatures came out, I don’t know. I only know that when a master was studying martial arts, he discovered the anti-law law, and accidentally discovered the anti-law space, and caught several anti-law creatures from it. come out.
Xiang Nan was thoughtful, what that brilliance discovered was probably the Great Netherworld.
And the little nether world that I went to, and the creatures in the little nether world, are the part that escaped from this world.
But about the black book, there is still nothing.
"Go down and have a look." Big Snake said.
Xiang Nan has been flying in the air. In fact, the space inside the mountain is still extremely huge.
There are various buildings scattered in it, and it is not known whether this was once a sect or an empire.
In short, it should be a very important place, so it is possible to find some strange treasures here.
Xiang Nan descended and found that there were a large number of mountain-like buildings on the ground inside the mountain. These vertical peaks were dug out of exquisite and elegant mountain palaces.
People should live here.
Looking around, there can be hundreds of thousands of such peaks, densely packed like a coniferous forest.
There are at least dozens to hundreds of palaces that have been pulled out on each mountain peak.
Xiang Nan reached out to touch a pillar on the palace, and the pillar quickly disintegrated, turning into dust all over the place.
"How many years has it been?" Xiang Nan said in surprise.
Big Snake said: "I'm afraid it's hundreds of millions of years away."
The human civilization that Xiang Nan knew about began about 300,000 years ago, but after seeing this place, he realized that what he was in was just one of many human civilizations.
It turns out that as early as hundreds of millions of years ago, there had already been a splendid human civilization.
He flew to a deeper place, looking back from here, he could no longer see the entrance of the mountain, and he didn't know if those warriors had chased him in.
The distance is too far to hear any movement at all. Standing here at this time, Xiang Nan is like Haoranzong standing in the East China Sea Province, looking at Haojing. It is impossible to see anything at such a distance. thing.
He found that these mountain buildings are arranged in a circle, like stars arching the moon.
If calculated in this way, if these buildings are regarded as a great circle, then where is the center of the circle
Xiang Nan speeded up and flew towards the core area at the speed of light. He arrived in a few seconds, which can be said to be a million miles away.
It is in this vacuum cosmic environment that he can use the speed of light so recklessly.
A magnificent palace appeared in front of him.
Xiang Nan didn't bother to check the size of this palace, but it was more than ten times bigger than the Haotian Palace he had seen before.
He floated half a meter above the ground, slowly drifting inward.
Then he discovered a situation, this place really looks like a sect, and this palace is like the inner sect, where the elders and suzerain live and practice.
Because he discovered a very familiar modern term that appeared in such an ancient civilization.
"The Hall of Creation."
The good fortune of Duo Tiandi is mostly described as pills.
Xiang Nan was excited. How powerful is the medicine left over from the civilization hundreds of millions of years ago
Two ancient stone gates stood in front of him. Xiang Nan didn't know what formation was imprisoning the stone gates, so he reached up and touched them lightly.
As a result, the stone gate was suddenly deserted, turning into dust all over the place.
"This will save trouble." Big Snake said.
Xiang Nan floated inside, sighing as he floated: "It saves trouble, but it's also troublesome."
"Even if the gate is like this, even if we find the elixir, I'm afraid we won't have a chance to eat it."
Sure enough, inside, there are a large number of simple pill furnaces and wooden shelves for storing pills.
Those wooden frames are not many, only three rows, each row has ten columns, two-thirds of the pills on it have been taken away, and one-third is left.
These elixirs appearing in such a place must be the elders of the sect who are qualified to consume them.
Although Xiang Nan knew that he had no chance to eat, he was still very excited.
He went to look at the brocade boxes and found the corresponding introductions. He took a deep breath after seeing them.
Eighth grade pill!
The first row of wooden shelves were all eighth-grade pills.
The second row of wooden frames are also all eighth grade.
The third column is even more frightening, it's all nine-rank pills!
Xiang Nan's tears were about to come down. Although two-thirds of the pills were gone, there was still a lot of one-third left.
But he really can't use these pills anymore.
He still harbored a ten-thousandth chance in his heart to touch a brocade box lightly.
As a result, as soon as the brocade box touched Xiang Nan's finger, it immediately turned into ashes. Including, the colorful and extremely beautiful spherical elixir inside, also scattered as soon as it appeared.
