"Although the planet is a sphere, because of gravity, we are on the planet, as if we are standing here, and the sky is always above us."

Jiang Bai drew a facet map, "In the interior of the planet, there are infinite rocks, hot magma, and all kinds of tangible materials, there may be cracks and canyons, but there is no space larger than the surface. ”

"And it's such planets, which make up the vast galaxy and the universe."

Albedo listened attentively, and this knowledge was not available to him, and although it may not be applicable to Teyvat, it was also very informative.

"In my opinion, if a person lives underground for a long time and does not see the sun, it will greatly affect his mental condition, but if he has never seen the sun, it may not be ........"

For example, he himself, who had spent a long time in a dark environment full of countless dangers, had a great mental impact, which was one of the reasons why he was extremely insecure before.

But with more than a year of life, this problem has improved.

"I thought Teyvat was also a planet, although it has gods and elemental power, it is still a planet in the universe......"

Jiang Bai sighed, Teyvat was breaking his cognition again and again.

No matter what false heaven, the constellation of life, or some abyss, or some Sky Island, it made it completely impossible for him to deduce Teyvat with common sense.

"Your memory is back?" Albedo looked up at him.

Obviously, Jiang Bai's memory has recovered a lot, otherwise he wouldn't know so many things.

"A lot of recovery." Jiang Bai nodded.

The memory of my hometown is too long, but even if it is very long, it is still instinctive when I mention it.

Albedo was not in a hurry to ask him about his memory, but continued with the topic just now.

He drew a horizontal line on the ground, "Is it possible, Teyvat is like this......"

"This is the ground with the horizontal line, and above the horizontal line is the sky, and below is the underground."

And the void of falsehood was over their heads, above the Isle of Sky.

He also drew countless interlaced lines under the horizontal line, and these lines were intertwined, like a big tree growing upside down.

"These are the silver-white ancient trees that run through the ground, and these connected branches record all the information of Teyvat, which is called the leyline."

Jiang Bai listened and watched him draw.

"If the tree heel is called a silver-white ancient tree, what about the crown leaves? It's impossible for us not to see a towering tree. Jiang Bai questioned.

A normal tree has roots and leaves.

If the roots are all over Teyvat, where will its leaves be?

Albedo asked a rhetorical question, "Have you ever heard of the World Tree?" ”

"Nope." Jiang Bai shook his head.

"The World Tree, like the leylines, stores all kinds of information about Teyvat." Albedo held his chin, "I wondered, could the World Tree be the ground part of this silver-white ancient tree?" ”

Jiang Bai scratched his head, it was the first time he had heard of such a thing as the World Tree.

But is the World Tree really the ground part of the Silver and White Ancient Tree? It's enough to record the information of the world, why is there a leyline and a world tree at the same time?

He remembered that there was a withered silver-white ancient tree in the snow-capped mountain, which should also be considered the ground part, right?

However, these are their conjectures and assumptions, and in the case of insufficient information, it is necessary to boldly make false conjectures and carefully verify them.

"Where will the World Tree be?" Jiang Bai tilted his head.

"I haven't seen it either, maybe in a world that I can't normally touch, maybe I'll be able to see it when I see the grass god of Sumeru......"

Albedo had never seen the World Tree, he only knew of it in various literatures.

The concept of the World Tree is very similar to that of the leylines, both of which contain all the information about Teyvat, which is why he wondered if the World Tree could be the above-ground part of this towering tree.

Skipping this topic for now, Albedo continued to paint on the ground, drawing a circle that enveloped the whole of heaven and earth.

This circle is like a bubble that envelops Teyvat in it.

"Teyvat has a boundary, and this boundary protects Teyvat, and Aunt Alice is working on mending it."

This is a certain thing, because Alice herself is the proof of it.

It's just that I don't know if the border is like this.

"Klee's mother?"

"Hmm." Albedo nodded.

Alice didn't put her young daughter in the Order for no reason, she had more important things to do than she could do with Klee.

"And what about outside the borders? What is it? ”

Jiang Bai's eyes looked at the part of the sand that was not wrapped in threads.

"I don't know, I haven't been to the border. Maybe Aunt Alice would know. ”

Albedo erased all the drawings on the ground, "At the moment these are my conjectures, and they are some hypotheses put forward by my research, but we don't know what they really are. ”

Although Albedo said that these were just his conjectures, Jiang Bai had a feeling that this conjecture might be very close to reality.

Either way, he wouldn't recognize Teyvat as a ball anymore.

Albedo brings the conversation back five hundred years.

"Five hundred years ago, the ancient kingdom of Kanria underneath was destroyed, and countless ruin guards poured out of the ground, and not long after that, there was one more tribe in the valley of Dadaupa that believed in the Black Sun."

He didn't know where the ancient kingdom of Kanriya was, and there could be many entrances and exits that ran through Teyvat.

At the time of the destruction of Kanria, countless dark plagues poured out, and the Seven Kingdoms were affected a lot.

It's just that he was not born at that time, and I can only know the situation at that time from books and literature.

In short, for all of them, the events of five hundred years ago are not pleasant memories.

"Did the former Kanria believe in Black Sun?" Jiang Bai asked a point-on-the-point question.

If the Kanria also believed in the Black Sun, he would have to wonder if these hilichurls could have changed from the former Kanriya.

Albedo was silent for a long time without speaking, which was equivalent to acquiescence.

His attitude made Jiang Bai's heart sound like a thunderbolt.

Goosebumps erupted from his hands, and endless coldness enveloped him.

People become monsters! Scary! It's too evil!

Since the discovery of the Teyvat Evil Sect, more and more incidents of the Evil Sect have unfolded before his eyes!

No wonder he wants the protection of the gods, without the protection of the gods, he has no sense of security!

He's going to have to hug Zhongli's thighs!

And Wendy, who has to bring him some wine from time to time, although he is a little wasted, he is also a god, and he can always work at a critical moment.

"The origin of the hilichurls is still a mystery, so let's not talk about it......"
