He had always thought that God was the strongest creature in the world, and it turned out that there was still an existence above God.

"And what exactly is Skye?"

"I don't know, there have been many people who have been to Sky Island in the past, but none of them have come back." Albedo shook his head. Sky Island already belongs to the highest level of content in this world, and it is not so easy to access.

"But why would a spike dropped from the sky cause this place to be a field of ice and snow?"

Jiang Bai is still a little incomprehensible, it stands to reason that at most he will smash out a crater, how can he smash it so much that even the climate has changed?

Katis had been troubled by this question before, but after reading many books and consulting many people, he also received an answer.

"Because of the leylines."

For Teyvat, the leylines are vital and closely related to human life.

"The reason why this place was full of greenery before was because of the protection of the leyline tree, but the spikes that fell from the sky destroyed the leyline tree, making the leylines here disordered, and naturally it was no longer full of greenery."

"Wait! What is the relationship between the leyline tree and the leyline? ”

Jiang Bai couldn't understand what these concepts meant.

Isn't the leyline some kind of conceptual network? What is a leyline tree? He was almost dizzy!

"Let me explain." Albedo knew better about these things, and he took the initiative to speak.

"In the depths of Teyvat's world there is a giant tree that runs through the world, and it is so large that the branches that reach out to the ground look like ancient trees. The roots of these ancient trees are connected deep in the earth, and the elemental channels formed are called leylines. ”

In short, the leylines are a web of roots from the roots of this giant tree that runs through the world for the elements to circulate.

"Roots... Concept Network... Tree Net ......" Jiang Bai muttered these words.

When he touched the leyline anchor, he could feel such a vast and boundless network.

Now it seems that this is a network of leylines built from the branches of the leyline tree.

Albedo's explanation is easier to understand than Zhongli's explanation of the conceptual network.

If understood in this way, then the leyline anchor is equivalent to the point marked in the network, and may also have the effect of stabilizing the leyline.

And because the leylines are the channels for the flow of the elements, the spikes falling from the sky destroyed the leyline trees, causing the leylines here to flow chaotically, and the ice elements occupied the high ground, so this place turned into a world of ice and snow.

"It is said that the ground bears witness to everything, and everything that happens above and below Teyvat is recorded in the leylines."

"That's really amazing......" Hearing Albedo say this, Jiang Bai couldn't help but sigh.

If the leylines really recorded everything, maybe they could find his past in the leylines.

However, how can we access the information stored in the leylines?

Jiang Bai thought about it, gave up and continued to think about it.

It was beyond his knowledge, and he couldn't figure out how to do such a thing.

Katis sighed.

Before, he was just an ordinary adventurer, what leylines, what white trees, he didn't know at all, and he didn't even have any concept.

He went to all kinds of dangerous places just to find treasures, and then sold the treasures he found to buy wine and drink.

He didn't have a family, his relatives were long gone, he had traveled through the golden desert of yellow sand, he had been to the dense rainforest with ancient trees, he had conquered the thunder and the waves, but he always felt that something was missing.

It wasn't until he picked up the senior's diary in the cave that he knew what was missing.

He just passed by those places as if he were a flower, and never seriously understood them, he claimed to be a good adventurer, but he could not say anything about the places he had visited.

Because he just wants to find treasure, he doesn't really like to be adventurous.

But he doesn't really love treasures very much, looking for treasures just to find something to do, and to have bragging capital in the tavern.

But in this snow-capped mountain, when the mountains and rivers were exhausted, he finally found his own fun.

He wanted to know the past, he wanted to dig into the history of the past, he wanted to study the stories that no scholar knew.

The process is boring and boring, but when the information is connected little by little, and the truth is slowly revealed, the feeling of joy and excitement is better than countless in the world.

Before he knew it, snow had fallen from the sky, through his illusory soul, and into the ground, merging with the ice.

"I've been exploring this snow-capped mountain for half my life, and it's become my second home. In the process of exploring the past history, it is as if I have returned to the ancient country that once flourished, and I have become a powerless part of it......"

Katis's voice carried a strong sense of powerlessness, and he reached out to try to touch the snowflakes falling from the sky, but he couldn't change anything after two worlds apart.

"It's impossible to find out why the sky is sending punishment, but now that I know all this, I can't act as if nothing happened."

"Even though this country has long disappeared in the wind and snow, and there is no descendant left, I still want to do something for this ancient country that has passed, even if I can't change anything......"

Jiang Bai and Albedo didn't speak, and listened to him quietly.

“…… You may think I'm a fanciful dream, but I really want to, I really want to pull out this nail that destroyed the ancient country! ”

However, he was already dead, dying in the process of getting close to this nail.

He has lost the ability to fulfill his wishes.

Snowflakes from the sky fluttered and fell into the fire, and in an instant they were evaporated by the flames, like moths.

But there are more "moths" in the sky, one after another, regardless of the heat of the flames, throwing themselves into this sea of fire, trying to extinguish this scorching flame.

Jiang Bai added a handful of firewood to the fire, calming down the somewhat smaller flames.

"It's going to be hard."

It was so difficult that he didn't know what to do.

Katis smiled feebly, "I know, but I have to try, don't I?" ”

Since there is no direct refusal, it is worth fighting for.

He is no longer alive, and he can only rely on these living people to complete this whimsical idea.

The cold wind came from afar, but it was blocked by the boulders, the flames crackled and burned, and no one spoke.

Albedo held his chin in contemplation, a position he had maintained from the very beginning when he met Katis.

He looked at Jiang Bai at the moment, waiting for his reply.

Jiang Bai flipped through the diary in his hand until the diary turned to the last page.
