Walnut used me to boost her sales performance.

"To prevent you from getting lost, I, as your younger brother, will kindly come down and meet you!"

He sat in the gondola and had Klee, who was playing in the snow with nothing to do, lower him down.

Meanwhile, the adventurers who had come up to check the situation and the intelligence agents from Liyue also arrived at the mountainside.

Also arriving was Sister Rosalia, who had been secretly working to resolve the crisis in Mondstadt.

The explosion on the snow mountain had been brewing for a whole day. During this time, some people left the snow mountain, while others rushed to the snow mountain day and night.

When Kaiya reached the bottom of the mountain and came out of the cave, he saw this large and impressive group of people.

Even someone as quick-witted as him was somewhat speechless at this moment.

"It's Kaeya! Kaeya, the cavalry captain of the Knights!" Someone recognized him and excitedly called out his name.

"Captain Kaeya, what exactly happened at the mountaintop?"

"Yes, yes, why did an explosion occur at the mountaintop?"

"Is it related to the Knights?"

Questions kept coming from the crowd, but Kaeya didn't rush to answer. Instead, he looked at Diluc in the crowd.

Diluc looked at him calmly and expressionlessly, seemingly not intending to have any interaction with him at this moment.

He cleared his throat and said loudly, "I know everyone is curious about what happened. The previous explosion was an experiment being conducted by our Knights. As for the specific details, we cannot disclose them to you."

As the cavalry captain of the Knights and the person directly involved in the explosion, he had an obligation to explain the situation to those who came to investigate.

His background and identity also lend him sufficient credibility.

As for the specific details, he didn't need to explain.

As expected, his words did not raise any objections from the group of adventurers from Mondstadt.

However, people are always curious, especially Wen Yuan, a Liyue intelligence agent who wanted to know exactly what had happened.

"Can we get to the top of the mountain?" he asked from the crowd.

Immediately, someone in the crowd chimed in, "Yeah? There's already a path to the top of the mountain?"

The speaker did not come from Mondstadt or Liyue, but from the more distant Winterlands.

However, this person from the Eastern Kingdom was not dressed like a person from the Eastern Kingdom, but rather like an adventurer, and looked like a Mondstadt person.

“Going up the mountain is certainly possible, but the path is difficult to traverse and extremely cold. If you all try to force your way through, you might be in mortal danger,” Kaiya said with a smile.

He didn't tell them exactly where the path was, meaning they would have to find the way themselves if they wanted to go up the mountain.

The crowd gradually dispersed; some went down the mountain to deliver messages, while others tried to find a way back up. The only one who remained was Diluc, the owner of Dawn Winery, the largest winery in Mondstadt.

And Rosalia, a nun belonging to the Church of the West Wind.

The Church of Favonius is affiliated with the Knights of Favonius and is a subordinate organization of the Knights. As a nun of the Church of Favonius, Rosalia naturally knows Kaeya and Diluc.

Rosalia has a slender figure, and even wearing a thick coat cannot hide her graceful figure.

Her skin had an unnatural white tinge, a result of long-term nocturnal exposure to sunlight.

She wore a nun's crown, but it wasn't as solemn as a normal nun's; she had modified it to be more aesthetically pleasing and practical.

Her eyes were dark and bluish-black, like the dark circles caused by staying up late for a long time.

She was fiddling with a small knife, quietly watching Kaya.

"Tell me, what exactly happened? I have no idea that the Knights have any approval for the snow mountain experiment."

"As for Abedo, I heard he's been doing experiments in the snow mountains, but I specifically went to look for him when I came here, and I still couldn't find him..."

Chapter 156 is suspicious.

As a top alchemist, Abeldo possesses extraordinary abilities, as well as extraordinary destructive power.

Not everyone in Mondstadt trusts him; Rosalia is one of the people who is quite wary of him.

As a covert "cleaner" of Mondstadt, maintaining suspicion and vigilance has become instinctive.

Her intuition told her that the explosion in the snow mountain was closely related to Aberdo!

She crossed her arms over her chest, and even through her thick coat, her great figure was still evident.

"You know my personality, so don't try to fob me off with some 'secret'."

As the dark side of Mondstadt, there are very few things that even she doesn't have the authority to do.

Diluc also looked at Kaeya, his expression indifferent, but his gaze was quite sharp.

"I'm also very curious to know what happened that could cause such a huge explosion."

"Oh dear, I just can't do anything with you two." Kaiya looked troubled, but didn't hide anything from the two of them.

"Actually, it's nothing major. Abedo conducted a blasting experiment and had a lot of bombs brought over. The explosion you saw was caused by the bombs exploding..."

Diluc: "...?"

Rosalia: "...?"

That's it?

It sounds reasonable, but it's also somewhat suspicious.

Rosalia frowned, and Diluc narrowed his eyes.

The two people who were secretly protecting Mondstadt in different ways were now feeling quite alike.

They did not have normal intelligence channels with the Knights, meaning that if Abedo had indeed submitted such an experimental request to the Knights and the Knights had agreed, they would only have found out about it afterward, just like they have now.

After all, it's perfectly normal for alchemists to conduct experiments, and no one would deliberately inquire about such matters.

The only surprise was the scale of this experiment.

Furthermore, the presence of Kaeya, the cavalry captain, here already represents, to some extent, official endorsement.

But since we're already here, we can't just leave like this.

They will only know the truth after seeing it for themselves.

"Where is the road up the mountain?"

Kaiya shrugged helplessly. "I knew you'd ask that. Come with me."

The two followed Kaiya to the top of the mountain.

With the baskets crafted by Abedo and their efforts to widen the narrow caves in their spare time, climbing to the top of the mountain became much easier.

Upon reaching the summit, the view from the top unfolded before them.

The mountaintop doesn't resemble a mountaintop at all; it lacks a sharp, towering peak. Instead, there's a huge depression in the center.

The dent looked like it was made by a bomb, as if it had always been there but was made bigger by the explosion.

Above this depression, there were pieces of pebbles of varying sizes floating off the ground, almost filling the entire airspace.

Meanwhile, Aberdo built a small laboratory within the depression and conducted his experiments as if no one else was around.

"Oh, it's the older brother who doesn't smile much and the nun sister who's rarely seen!"

Upon seeing the two, Klee exclaimed in surprise.

She had met the two of them, but her knowledge of them was entirely based on those descriptions.

She had met Diluc a few times, but he always seemed unhappy and didn't smile much.

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

As for Rosalia, she had seen her a few times in Mondstadt and Favonius Cathedral. In Klee's eyes, she was different from the other nuns, but that was about it.

"Klee, what are you doing here?" Rosalia's enthusiasm suddenly waned.

Klee here represents a lot.

"Hehe, Klee is here helping Brother Abedo with his experiments! Klee has been a great help!" Klee said proudly, hands on her hips.

Diluc glanced at Klee, then at Kaeya.

Kaiya nodded and shrugged, the meaning of which was self-evident.

He's telling the truth; you can ask Klee if you don't believe me.

Rosalia, without any hesitation, tried to extract information from him like a child, "Oh? What help did Klee provide?"

"Klee installed a ton of explosives! All those boulders were blown up by Klee!" Klee pointed proudly at the boulders floating in mid-air.

She was the great hero who blew up the bad nail!

Rosalia remained silent.

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

She pinched Keli's cheek, a little annoyed, but didn't say anything.

"What are those fragments of crystal floating in the air?" Diluc asked.

These fragments of crystal are blue, some covered by a stone skin, while most are simply blue crystals.

These things were floating in mid-air, and they looked quite unusual.

“Those are the things we destroyed with bombs,” Kaeya said, then looked at Klee. “Klee, bring out the photos.”

"Oh!" Klee took out the group photo they took in front of the Frost Spikes and handed it to Kaeya, who then passed it to Diluc.

This photo shows what this place originally looked like, and what it looked like before the Frost Spikes were destroyed.

"This thing is called the Frost Nail. It fell from the sky thousands of years ago and has been stuck on the mountaintop ever since. These fragments are the remnants of the Frost Nail after it was destroyed..."

Rosalia leaned closer, looked at the photo, glanced briefly at the Frostfire Nail, and then her gaze fell on Jiang Bai.

"Who is this?"

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

"Why would a Liyue person be involved in the Knights' experiment?" Rosalia questioned.

“He’s my lab assistant, what’s wrong?” Abedo walked over at that moment.

He had already spoken to Kaiya about how to explain things here yesterday, and told the public that they were conducting some kind of secret experiment. He had also informed Grand Master Falgar of the Knights of the Order about this.

When we get back, Kaiya will submit a complete report detailing the whole story.

Meanwhile, to avoid unnecessary trouble, Jiang Bai and Hu Tao, who had participated, were collectively referred to as Abedo's experimental assistants.

Once Grand Master Falgar has fully understood the cause and effect, it will be up to him to decide whether the matter should be classified as secret.

"Although I really want to ask Abedo why you would hire a Liyue person as your assistant, I'm sure you have many reasons, and I'm too lazy to ask. Since the explosion was just caused by the experiment, I'm too lazy to worry about it."

Rosalia stretched and resumed her usual lazy demeanor.

Before leaving, she looked at Abedo, her eyes flashing with a dangerous light.

"However, Mr. Alchemist Abedo, please consider the consequences before doing such things next time."

Chapter 157 sounds unbelievable.

Rosalia is gone; only Diluc remains from among those who have come before her.

After asking Kaeya to look after Klee, Abedo returned to the lab to continue his experiments.

Diluc looked at Kaeya, and as their eyes met, he calmly asked:

"What exactly happened? What kind of experiment was it? And why destroy this Frost Nail?"

Before Kaiya could ask, he continued:

"Don't try to fob me off with what you just said. I know you too well. What you just said is part of the truth, but it's only a small part. I need to know the whole story."

"You can't hide anything from you." Kaiya shrugged helplessly, but his signature smile remained on his face.

"Look, do you see that secret realm? Go in and take a look, then I'll answer your question."

Diluc nodded and walked towards the secret realm without looking back.
