I can see experience bars after being transported to another world.

"But the fact that you even asked this question proves one thing," Oden said, his tone turning slightly disdainful. "Your understanding of the ocean of knowledge is practically still at the very beginning, just the basics."

"Huh? Really? I think my understanding of the sea of ​​knowledge is pretty good." Lu Yuan also became interested at this moment.

"Through our continuous exploration at that time, the sea of ​​knowledge was divided into three regions. Of course, these regions were divided by ourselves and cannot be considered as official records. We divided them into the Radiant Region, the Deep Region, and the Unknown Region."

"The Colorful Zone is the area you'll encounter most often, and it's the first colorful place you see every time you enter. Its name comes from the colors."

"The most humans can reach so far is only its shallow layer, where there are countless seas made of knowledge, and countless strange creatures swim in them, such as the knowledge worm that you are connected with. There are also some ruins and corpses."

"A corpse?" Lu Yuan realized that he had seen the huge corpse during the second fishing operation in the Sea of ​​Knowledge.

"The remains of those who died inside in search of a glimmer of hope, those who died while trying to gain knowledge, are all in the Rainbow Zone. There are also some buildings that were swallowed up by the Sea of ​​Knowledge in the Rainbow Zone."

"And in the Deep Zone lies an even deeper realm," Oden's voice lowered. "Few who go there come back alive, and I suppose I'm one of them."

"As for the unknown area, it is a place that no one has ever been to, or rather, everyone who has been there has died. So no one knows what is going on inside, and no one can explain it clearly. This unknown area is just a name we gave it."

Listening to Auden's explanation, Lu Yuan carefully recalled that the scenes he saw when he entered the Sea of ​​Knowledge each time were indeed not much different, all being an endless, colorful ocean. However, the scenes he saw each time seemed to have some subtle differences.

The first time I entered, it was a boundless expanse of color, but during the fishing operation, the interior of the Sea of ​​Knowledge was a vast sea of ​​blood, with countless buildings deposited within it, which should be the ruins Auden mentioned.

Apart from that, the Sea of ​​Knowledge seemed to have nothing else unusual.

But after Auden said that, Lu Yuan realized that the Sea of ​​Knowledge was not what he had thought, or rather, his understanding of the Sea of ​​Knowledge seemed to be only at the initial surface level.

However, it's not entirely surprising what lies beneath the vast ocean of knowledge.

Lu Yuan suddenly realized something and asked, "Are those black characters on the body? No, or should they be in some unknown area?"

"I'm not entirely sure where the black text is either, but it's most likely in an unknown area," Oden said.

"Moreover, the depths of the sea of ​​knowledge are extremely difficult to reach, very difficult for us, but perhaps not so difficult for you. Since you were able to summon those black characters that I've never even seen before, theoretically you should be able to infiltrate even deeper. However, if you don't take the initiative to go, I estimate you'll never reach those deeper areas in your lifetime."

Lu Yuan was somewhat confused by Auden's words.

That shouldn't be the case, right? If we simply divide the sea of ​​knowledge into shallow, medium, and deep, then like the sea itself, if you just dive down, you'll eventually reach some depth, right? It shouldn't be that difficult.

Lu Yuan's question made Auden laugh.

"It's not as easy as you think. It's very difficult to travel from the Radiant Zone to the Deep Zone because the Sea of ​​Knowledge is not a flat plane like the world we live in now. Instead, the Sea of ​​Knowledge is composed of countless irregular planes superimposed on each other. There is no up or down, left or right, no north or south, and no concept of direction."

"You see the endless, colorful sea constantly shimmering within it, but in reality, it is just a small piece of the world within the vast rifts or distortions of the sea of ​​knowledge. It is an incredibly chaotic place, and so far there is no better way to find your way. Therefore, by normal means, you will never be able to reach the deep zone; you will only move from one colorful zone to another."

"Then how did you get there? If even I couldn't get there, how did you get there?" Lu Yuan asked, somewhat confused and curious.

"Of course, there are some special methods," Auden said. "We have a way to catch the Knowledge Worm in the Sea of ​​Knowledge, yes, the little worm that you have a connection with. But we don't catch the real thing, we catch its larvae, refine them into medicine, and use them to attract a being in the deep zone that is very similar to the Knowledge Worm. Only by following its tracks can we find the deep zone."

Deep within Lu Yuan's left eye, the Worm of Knowledge seemed to stir, but quickly fell silent again, as if it didn't care much about these things.

"What does that deeper area look like?"

"The colors aren't as vibrant as in the Rainbow Zone," Oden said with a hint of reminiscence. "But the knowledge contained there is something that can't be found outside. Some completely lost knowledge is there, so if you want even rarer knowledge, you have to go to those places. However, I didn't see the black writing you mentioned there either, so it's highly likely that this thing only exists in unknown areas."

Lu Yuan's heart skipped a beat. He knew he had to be extra careful next time and never mess with those black characters so carelessly again. When opening the rift in the Sea of ​​Knowledge in the Northern Territory, he had to be extra cautious; if he saw any black characters, he should either close the door immediately or try to drive them back.

However, at this moment, Lu Yuan suddenly realized something.

"So, according to what you're saying, Auden, if I'm just browsing through the sea of ​​knowledge and pay a little attention, as long as I don't go into the deepest parts, does that mean I'll never make a mistake?"

Oden rolled his eyes at Lu Yuan, annoyed.

"This is the key point I want to tell you: once you spend too much time wandering in the sea of ​​knowledge, you will be called back by the sea of ​​knowledge. At that time, you may not be able to find your way back, and the longer you stay, the more obvious it will be."

"Calling? Does the Sea of ​​Knowledge still call?" Lu Yuan was somewhat taken aback, because he had entered the Sea of ​​Knowledge several times before, but he had not noticed anything about it that was attracting him.

"This thing takes into account the fixed time you spend in the sea of ​​knowledge, and has absolutely nothing to do with your level of rationality," Auden explained, emphasizing each word. "Once you've been in the sea of ​​knowledge for more than half an hour, you'll develop a sense of belonging to it, like you're at home."

"Do I feel a sense of belonging like I'd find a home? I don't think so."

"Of course, you haven't been here for more than half an hour so far, have you?"

"Afterwards, your body will not experience any abnormalities, and you will not even be aware of any problems. You may even feel that the influence of the Sea of ​​Knowledge on you is gradually decreasing, and the rationality you need to expend to navigate the Sea of ​​Knowledge will begin to approach zero."

Upon hearing this, Lu Yuan's back slowly tensed up.

The fact that the consumption was gradually approaching zero sounded like a great thing, but coming from Auden's mouth, it just didn't sound quite right.

"This is precisely when the Sea of ​​Knowledge is at its most dangerous," Auden's voice began to carry a hint of seriousness.

"If you don't realize it immediately, you will completely lose control of your body, and your soul will begin to be eroded by the sea of ​​knowledge. If you haven't left by half an hour, and it reaches an hour, you will be completely lost in the sea of ​​knowledge. If you're lucky, you might retain a shell, like the shell of this suspending person I'm in now, which is how it was created; if you're unlucky, you'll become a small clump of knowledge drifting in that sea, and your consciousness will be completely erased, turning into nourishment for the sea of ​​knowledge."
