Albedo, as a top alchemist, has extraordinary abilities, but also extraordinary destructive power.

Not everyone in Mondstadt was reassuring of him, and Rosalia was the one who was quite wary of him.

As a secret "scavenger" in Mondstadt, it has become instinctive to be suspicious and wary.

Her intuition told her that this explosion in the snowy mountains had a lot to do with Albedo!

She has her hands around her chest, even through the thick coat, she can't stop her good figure.

"You know my character, but don't prevaricate me with any "secrets". ”

As the dark side of Mondstadt, there are not many things that even she has permission to do.

Diluc looked at Kaeya as well, his expression was cold, but his gaze was rather sharp.

"I'd also like to know what happened to cause such an explosion."

"Oh, I can't help it." Kaeya looked distressed, but didn't hide it from the two.

"Actually, it's not a big deal, it's just that Albedo carried out a blasting experiment, and people brought a lot of bombs over, and the explosion you see is the ...... caused by the explosion of the bombs."

Diluc: "......? ”

Rosaria: "......? ”

That's it?

It sounds reasonable, but it's a little suspicious.

Rosalia frowned, and Diluc's eyes narrowed.

The two men who were secretly guarding Mondstadt in different ways were in the same mood at the moment.

They don't have a normal intelligence channel for the Order, which means that if Albedo did send such an experiment request to the Order, and the Order agreed, they would only be aware of the movement after the fact, as it is now.

After all, it's so normal for alchemists to do experiments, and no one would bother to inquire about this kind of thing.

The only surprise was the movement of this experiment.

In addition, Kaeya, who is the captain of the cavalry, is also here, and to some extent already represents the official endorsement.

But it's all here, and of course it can't just go.

What the truth is, they have to see with their own eyes to find out.

"Where's the way up the mountain?"

Kaeya spread her hands helplessly, "I knew you would ask that, come with me." ”

The two followed Kaeya to the top of the mountain.

With Albedo's basket and the widening of the narrow cave in their spare time, it was much easier to get to the top of the mountain.

When they reached the top of the mountain, the scene at the top of the mountain also unfolded in front of the two of them.

The whole summit does not resemble the top of the mountain, there is no pointed towering peak, only a huge pit in the center of the summit.

The crater looked like it had been blown out by a bomb, as if it had already existed, only to get bigger because of the explosion.

Above this crater were pieces of rubble floating off the ground, of various sizes, covering almost the entire air.

Albedo, on the other hand, set up a small laboratory within the confines of the pit, where no one was doing his own experiments.

"Hey, it's a big brother who doesn't like to laugh and a sister who rarely sees a nun!"

Seeing the two of them, Klee exclaimed.

She had seen these two people, but her perception of them was completely stuck in those descriptions.

Diluc had met her a few times, but each time he didn't look very happy and didn't like to laugh much.

For Klee, who is in the mood like a little sun every day, it's hard to understand why he's always unhappy.

As for Rosaria, she had seen her a few times in Mondstadt and Favonius Cathedral, and in Klee's eyes, she was not quite like the other nun sisters, but not much else.

】

"Klee, why are you here?" Rosaria's energy for this matter suddenly leaked.

Klee has represented a lot of things here.

"Hehe, Klee is here to accompany Brother Albedo in experiments! Klee was a great help! Klee's smug cross.

Diluc looked at Klee, then at Kaeya.

Kaiyanu shrugged his shoulders, and the meaning was self-evident.

He was telling the truth, and if you didn't believe Klee, you would know.

Rosalia had no scruples about getting information like a child, "Oh? How did Klee help? ”

"Klee installed a lot of explosives, and all those broken rocks were blown up by Klee!" Klee pointed to the broken stone floating in mid-air, her expression proud.

She's the big hero who blew up the bad nails!

Rosalia was silent.

Then silently in his mind, Klee's danger level was raised by one level again.

She pinched Klee's face a little unpleasantly, but didn't say anything.

"What are those broken crystals floating in the air?" Diluc asked.

These fragments are blue in color, some are covered in stone skin, and larger are more or less pure blue crystals.

These things float in the air, which is unusual no matter how you look at them.

"That's what we blew up with our bombs." Kaeya said, then looked at Klee, "Klee, take out the picture." ”

"Oh!" Klee pulls out the photo they took in front of the Frosty Spike and hands it to Kaeya, who hands it to Diluc.

This photo shows the original appearance of this place, and the appearance of the Nail of the Cold Sky before it was blown up.

"This thing is called the Nail of the Cold Sky, it fell from the sky thousands of years ago, and it has been inserted on the top of the mountain, and these fragments are the fragments of this Nail of the Cold Sky after it was blown up......"

Rosalia leaned over, looked at the photo, briefly glanced at the Cold Sky Nail, and her eyes fell on Jiang Bai.

"Who is this?"

"This is Jiang Bai, a native of Liyue, the assistant of this experiment, who left yesterday."

"Why did one of the Liyue people participate in the Knights' experiment?" Rosaria questioned.

"He's my lab assistant, what's wrong?" Albedo walked over at this point.

As for how to explain what happened here, he had already communicated with Kaeya yesterday, and said that he was conducting some kind of secret experiment, which also greeted the Grand Master of the Knights, Falgar.

When she returns, Kaeya will submit a full report detailing the whole story.

At the same time, in order not to cause unnecessary trouble, Jiang Bai and Hu Tao, who had participated in it, were collectively referred to as Albedo's experimental assistants.

After Grand Master Falgar fully understood the cause and effect, it was naturally up to him to decide whether this matter would be classified as a secret or not.

"I'd love to ask Albedo why you hired a Liyue man as your assistant, but there must be a lot of reasons for you, and I don't bother to ask. Since the explosion was only caused by experiments, I don't bother to worry about it. ”

Rosalia stretched, returning to her usual lazy appearance.

Before leaving, she looked at Albedo, her eyes glinting dangerously.

"But the great alchemist, Mr. Albedo, please consider the impact before you do this kind of thing next time."
