Caiyun listened and said, "I understand, but I still have two last questions. ”

"If you have any doubts, ask them now, don't keep them in your heart. ”

Caiyun then asked: "The abyss is full of dangers, and there are space-time vortex everywhere that 'eats people without spitting out bones', even if the door of time and space is opened, mortals should not be able to enter the abyss?"

"The answer is very simple, the dragon god must have thought of this when he set up the 'law', so when the gate of time and space is opened, the thick fog and the space-time vortex mixed in it will inevitably be dispelled. What about the other question?"

"Cortana, where do you think the danger of that dragon mound is, and what about the mountains and rivers, how can those explorers be killed and injured countless times?"

"The dragon mound is located underground, and the environment is extremely dim, so it can be said that you can't see your fingers. Although we can use our eyes instead of eyes, mortals obviously do not have this ability. Even if they had prepared torches beforehand, the range of visibility would have been greatly reduced compared to the blue sky and white sun.

We don't know where we'll go through the plane-time portal, but my instincts tell me it's at the top of the hill. In that environment, if you don't pay attention to the terrain at your feet, it is easy to fall down the hill and break your bones.

Therefore, this uneven terrain is still very dangerous underground. But you're right, the terrain alone may not cause them many casualties, after all, a misstep will immediately attract the attention of others, and everyone will be cautious to prevent the same tragedy from happening again. ”

Marina frowned when she said this, and after thinking for a moment, she said, "I think there may be some deeply hidden creatures in that dragon mound that have escaped the perception of the dragon god. ”

Caiyun was shocked when he heard this, and exclaimed, "What? There are even creatures that the dragon god can't detect? Could it be that its cultivation is still above the dragon god? If we rush in, wouldn't it be more than lucky?"

"Caiyun, you're going to be mistaken. In fact, creatures with extremely strong concealment abilities can easily avoid anyone's perception, and only saints can detect their existence. The White Fox Clan has an excellent technique of concealing aura, which can completely make their sense of existence disappear for a period of time, which is very clever. In fact, I just rely on intuition to guess, without any real evidence, just to increase our vigilance. ”

"Concealment? Okay, I see. Unexpectedly, because of a few questions, it took a lot of time, so we went to the tower to search for literature. ”

Marlena didn't mind this time, and said with a smile: "The questions you just talked about are very meaningful, even if you don't ask now, I will definitely explain them to you in detail in the future, and I am not wasting time at all." Caiyun, you must regain your self-confidence in the future, trust your own judgment, and don't always blame yourself for no reason. ”

"Cortana, don't worry, I will adjust my mentality as soon as possible, and I won't let my mood go down all the time. ”

Caiyun clenched his fists and assured Marlena with an unusually determined expression.

"If you have this awareness, I don't have to worry. ”

The two of them then walked the same step to an arch at the base of the wooden tower, and Marina swept the arch with a spiritual power, and after making sure that there was no mechanism behind it, she stepped forward and gently pushed it away.

The two entered through the arch together

In the midst of the wooden tower, a new space greets you.

It is very similar to those huge scripture pavilions, with dense mahogany bookshelves everywhere, covering almost all the space in the tower.

The rows of bookshelves are arranged very neatly, and the distance between all the bookshelves is exactly three feet, which is exactly the same, full of the rigorous atmosphere of the "royal family". The distance of three feet was enough for the two of them to pass side by side, which was just right for Marina and Caiyun, one more was too wide, and one less was too narrow.

The wooden tower has eighteen floors, but only this first floor has more than 100 bookshelves. The shelves are filled with bamboo slips, and there are hardly any gaps to be seen.

In such a dizzying sea of books, Caiyun and Marina both looked dumbfounded. The inside of the wooden pagoda was clearly far beyond the imagination of the two.

"It's incredible, there are such a huge number of ancient documents stored here, it is simply an ocean of knowledge, such a magical place, this is the first time in my life. Marina couldn't help but admire.

"Cortana, you're happy, I'm not happy. Don't forget, there are eighteen floors here, and maybe each floor has so much literature. We don't know where the historiographical documents are, and when will we find them, even if there is still a lot of time before the dragon mound opens, we can't afford to spend too much time here. ”

Caiyunxiu frowned, looking at the uncountable bamboo slips, and felt more and more that the future was bleak, and the difficulties and obstacles stood in front of him.

"Alas, when it comes to critical moments, your usual agility is gone. But you don't have to worry, I'll just figure it out, and I'll make sure that we can find all the literature we need in one day. ”

"Cortana, what can you do? Both of us don't know anything about this place, and we don't know anything about it. I don't know how these documents are arranged, and I don't have a clue about the types of documents in each layer. Unless you've been here before, what can you do to get us the literature we need in one day?"

"I didn't expect you to be really stupid. Think about the same principles or methods that primates use to place things. Marina snorted.

"Principle?method?"

Caiyun couldn't help but fall into deep thought, and it took a moment before she came back to her senses.

"Are you saying that no matter what race they are, when they put things in place, they like to put things of the same kind together so that they can easily find them later, yes or no?"

"Of course, what race will have books in the Scripture Pavilion. If you put completely different types of books together, you will be confused when you look for them in the future, and you will only waste precious time, who would want to do such a thankless task? I don't believe that there is such a stupid race in the world. Marina said with great certainty.

"But it's a race we don't know about, and we can't use our normal way of thinking to guess their psychology, can we?" Caiyun asked.

"Caiyun, your idea is too complicated, even a little unrealistic. I'm sure that the palace is built so magnificently, the bookshelves are so neatly arranged, and everything seems to be in order, the race will do the irrational behavior you imagine. If it's my judgment

If there is a mistake, then we don't have to waste time here, just go straight to the dragon mound. What do you think?"

Marlena was so confident that she knew exactly what wisdom meant, and therefore had no doubts about the way the literature was arranged.

"Okay, just do as you say. If my thinking is once again very different from the truth, it proves that I should indeed change the way I think about things. ”

Marlena bowed her head and said, "You always complicate simple things in your mind, and this kind of problem should indeed be corrected." In fact, it is very simple to verify the arrangement of these documents, we only need to randomly select two bamboo slips on the same bookshelf to see if the content is similar. If these three bamboo slips belong to the same category, it proves that my judgment is correct. In this way, even if the wooden pagoda has eighteen floors, it is easy and effortless to find the few documents we need. ”

"It's worthy of Cortana, and she really thinks clearly, in one sentence. Let's start with the bookshelf in front of us, and if we're lucky, maybe the historiographical literature is on this level. ”

"Not really. Regardless of race, the status of the history books is very important, and I dare to conclude that they would never dare to put the history books on the first level. ”

As Marina spoke, Caiyun had already stepped forward, picked up a rolled-up bamboo slip from the bookshelf, and unfolded it to look at it.

After two glances, Caiyun frowned and turned to Marlena for help.

"Cortana, the text on this bamboo slip seems to be in Northern Regions, and I can't understand it at all. ”

Hearing this, Marina smiled and said, "Haha, this is Beiju Luzhou, and the Northern Regions script has been formed since the ancient times. Although the Datang script is commonly used today, it must not have been popularized in Beiju Luzhou at that time. ”

Caiyun then handed the bamboo slip in her hand to Marina, hoping that she would be able to read the words written on it.

Marina took it and looked at it cursoryly, and said, "You are not mistaken, this is indeed the script of the Northern Regions, although there are some slight differences from today's text, it is not obvious, and it can be read completely." ”

Caiyun suddenly breathed a sigh of relief and said happily: "That's fine, if you can't read it, we can just give up." What's written on this?"

"It seems to be a literature like a story, and it has no reference value. ”

"Is it the kind of folklore that can't be verified?" Caiyun asked.

"That's right. As I expected, these books are usually placed on the first floor because they don't matter, even if they are stolen. Now I only need to read two more bamboo books to confirm my judgment. ”

With that, Marina put the bamboo slip in her hand back to its original position, and took another bamboo slip from the same bookshelf and took a look at it. After a moment, Marina nodded smugly and smiled, "Sure enough, as I expected, the story described above is even related to the one just now, and it seems that their method of arranging these documents is very rigorous and not chaotic at all." ”

Caiyun had already walked to the front of another bookcase, and after taking a random bamboo slip from it, he returned to Marina's side. Marina took the bamboo slip from Caiyun's hand, unfolded it, and immediately showed a relieved expression.
