Honkai: It’s broken, I have become the Herrscher of Corrosion?

Kiana and Mei were both surprised to hear Dr. Tesla's call.

"Missing? If the two Xi'ers go all out, they will definitely be able to reach the standard of an S-class Valkyrie. According to Senior Cheng Lixue, Susanna's actual combat power must have reached the standard of an A-class Valkyrie. In Changkong City, they can be made to disappear without anyone noticing..."

"By the way, Doctor, Bronya is... okay, right?"

Einstein's calm voice came from the communicator:

"Something's wrong with Seele. Miss Bronya is indeed more anxious than anyone else. She has already put down her work and is on her way to help us with the investigation."

"According to preliminary investigations, Changkong City experienced abnormal spatial fluctuations during the period when Xi'er and the others disappeared."

Enosia sighed:

"Misterlin...she still likes to talk to herself like this."

"Ms. Ino...what else do you know?"

"Xi'er and Susanna...are probably already in the Quantum Sea."

(Switching to Susanna's perspective...)

Before coming to Changkong City, she would never have imagined that after the Great Collapse, the process of coming to Changkong City with Xier to capture a mysterious Faceless Man would be so full of twists and turns.

Just now, the rain and the water faded away, and the sky and the buildings disappeared.

The surrounding scenery changed rapidly, as if a layer of complicated outer shell had been knocked off, revealing the true appearance inside. She rubbed her eyes and used various methods to confirm that she was not dreaming.

"Why did Changkong City suddenly become like this? What kind of trick is this? Optical projection? Psychological hypnosis?"

"Susanna, calm down for a moment."

"But...Xier, where exactly is this place..."

Unlike Susanna, who looked confused, Xier felt as familiar with this place as if she were back home. She understood in an instant that the landscape before her was not the product of any illusion or trick, but a real space.

"This... is the quantum sea."

"Eh!? Is that the quantum sea... where multiple worlds can exist at the same time, where everything becomes chaotic and there is no pattern to be found... and once you step into it, it is difficult to get out?"

"No, no, that's not the question... Isn't the Quantum Sea the place where you, Xi'er, were trapped in the past?"

"Yes. In the past, I entered this place due to an... accident, and drifted in the cracks between many worlds for a long time."

"Speaking from personal experience... it's hard to believe, but we are in a similar situation now."

"But we were just in Changkong City! I remember Lady Rita said that the conditions for entering the Quantum Sea are actually very harsh. Even with the use of a specialized facility like the Eye of the Abyss, there is no guarantee of 100% success."

Xier's mind quickly flashed back to what had just happened.

They had already cornered the Faceless One, whose true identity was a gray snake, but suddenly, several cracks appeared in the surrounding space; when they came to their senses, they were already in the quantum sea that they could never easily step into.

"As far as I know... the gray snake does not have the ability to send people into the quantum sea. According to what it just said, our current situation is related to the feather rabbit..."

Xier looked back on the process of investigating the case in Changkong City, and her doubts grew more and more serious. She vaguely felt that she seemed to be caught in some ingenious and hidden design.

But at this moment...

"Xi'er...I seem to...something is wrong."

"Suzanna...what's wrong with you? You look...why are you so pale?"

"I don't know... Weird, did I eat something wrong today? I felt a little dizzy during the battle just now..."

"Now... staying in this space, the uncomfortable feeling seems to be getting stronger and stronger... a bit like... the feeling of airsickness..."

(Strange, I remember that unlike Theresa, Susanna is actually very adaptable to the Quantum Sea... How could this be?)

(…Xier, have you noticed anything else wrong? This quantum sea seems very strange!)

[…Hmm, this place is indeed very strange…]

(Great, at least you're okay!)

[No. Strictly speaking... my condition is not quite right either.]

(Huh? Are you feeling uncomfortable too?)

[Uh... that's not the case. Rather... in a sense, I am in a better state now than at any other time...]

[Although this may scare Susanna, maybe she will feel more comfortable after we do this. By the way, you'd better not be too surprised, okay? After all...]

As "another Seele", this is her second time to display similar abilities outside of that "mind room".

The first time was when she faced Bronya many years ago - unfortunately, Seele mistook her for a demon at that time, which led to a bizarre misunderstanding.

After all, that was a failed awakening in itself...but the situation now seems to be completely opposite to that time.

Just like that, Hei Xi crawled out of Bai Xi's body and stood on the ground with his feet firmly on the ground like a normal person.

"After all, in this space, we can separate easily like this."

"Hmm... am I too dizzy? Xi'er, why are there two of them?"

"Well, we always have two."

"Ah... It seems that this is really an illusion... Ah, it hurts!"

The so-called "hallucination" gave her a heavy slap on the forehead.

"You fool. Are you sober now?"

"The airsickness... seems to be slowly disappearing... but Xi'er still has two?"

"Nonsense. It's because I was able to escape from Xi'er's body that you feel a lot more relaxed now."

"?"

"...To put it simply, when the three of us exist independently, the quantum sea can form a stable structure around us, just like a triangle will not be squeezed and deformed by external forces..."

"Wait, wait... you've said so much... can someone tell me why there are two Xi'ers here at the same time?!"

"..."

"Hmm... There is actually such a thing..."

"I'm sorry, I didn't have the chance to tell you before. Actually, when you saw me in a daze before, I was talking to this "Xi'er"."

"Haha, you two really have a good relationship."

"Of course, after all, we have been together for a long time... Okay, okay, let's hurry up and talk about business. What I just said is the reason why there are two Seeles...

And “why there are two Xi’er here at the same time”, even I don’t understand it myself.”

"Ugh?"

"Don't get me wrong... What I mean is that I don't understand why the being behind the scenes - I think it's Yutu - would make this place so that a non-corporeal being like me can move freely. Maybe it's because... maybe her own taste is very weird."

"In short, we should not stay here for long. We need to use our previous experience to get out of this predicament. There are a lot of world bubbles floating in the quantum sea. If we can't find a way to return to reality directly from here for the time being, perhaps it would be an effective approach to first look for world bubbles that we can contact, and then gradually confirm their coordinate relationship with the real world."

"So... we are actually lost in the quantum ocean?"

"Idiot, you got it the other way around. Because it's the quantum ocean, getting lost is inevitable.

Unless we can use the necessary equipment like Yulandel to always anchor our coordinates with the real world.

Of course, it's too late to talk about this now. In any case, we can't just sit there and wait for death. Let's move to an area with a more stable spatial structure, and then gradually find a way to return to reality."

"Does Xier know where we should explore?"

"Yeah. I can feel that aura... There is another relatively stable world nearby. Let's go there first."
