To create Honkai Impact 3rd in a world where Kallen exists.

"What a strange sight... Is this architecture from the First Civilization Era?"

Mei looked around warily, but couldn't find the person she had spoken to. She was filled with admiration for civilization as she gazed at the exquisite architecture before her.

This was a landscape she had never seen before in this civilization.

This also made her more convinced of what the other person said.

This... was the first woman she saw when she came in.

"How about it? It must seem very avant-garde to you, right? But in my time, it was just an ordinary house."

The voice in the air seemed to carry a hint of amusement, and it delivered the explanation very aptly and promptly.

She is a perfect match for Mei.

Mei's appearance is naturally that of the Herrscher of Thunder, whom people are familiar with. She is currently wandering in the mysterious space of this World Serpent Base, guided by Kevin, to search for the unknown secrets.

It seems I encountered a strange and beautiful girl, but now that I think about it, my memories of her are somewhat hazy...

Who was the other party...?

Seemingly oblivious to Mei's inner turmoil, the talkative girl continued her eloquent discourse, more like she was reciting a list of points to note than explaining them.

"This sense of displacement due to the epochal gap is part of the fun of exploring the wonderland of the past. Look forward to encountering even more unbelievable sights!"

"Back to the main point, you seem to be doing much better now, it's time to move on to the next step~"

"Just... explore freely. It's your first time, so don't feel guilty."

"There will be no punishment for failure, and no one will blame you for poor performance. Don't worry, I'm always here for you."

A girl's voice, hidden in the background, seemed to chuckle softly, soothing the visitor's thoughts. This was a guest she had taken the initiative to welcome; Kevin hadn't forgotten her instructions.

Then... let's start from now!

I'm really looking forward to it! Where will the other person end up?

"So my goal is... to defeat someone? To find something?"

Mei frowned and asked, still somewhat confused about the situation. She had inexplicably ended up fighting the monsters inside... and it seemed that she had been strengthened by some additional factor here.

Is this place... really still reality? For some reason, a question arose in her mind.

"Hmm~ Probably not. You just need to explore and experience it. After all, this is just an attempt, so don't overthink it!"

"No Herrscher has ever set foot here before. For both of us, this is... our first experience?"

"..."

"The situation is roughly clear, but there's still one crucial question,"

Mei nodded slightly, then asked a question that left the person behind her speechless.

"--Who are you?"

"...Hey, are you...seriously? I just introduced myself a few minutes ago."

The gentle voice behind him now carried a hint of distress, unable to cope with the other person's forgetful nature.

"Seriously...are you deliberately flirting with me? How could you do something like that to a girl you just met?"

"You have such a cute face, but your mind is surprisingly mischievous."

One can almost foresee the girl behind him pouting and furrowing her brow in a playful manner.

Mei remained unmoved by the teasing voice, for her past traumatic experience had robbed her of the gentleness she once always displayed.

She simply replied coldly.

"Okay, I have no other questions."

"Well then... let's not delay, let's go!"

But the girl was not affected by her cold voice; instead, she remained as enthusiastic and cheerful as ever.

I will bestow my blessings upon you, and your soul will shine even more brilliantly—

She sang softly and gently, but her wicked intentions were quickly revealed.

"Raiden Mei's Past Paradise Adventure begins now!"

Then, on the right side, a row of engravings appeared, displaying different effects. From the engraving column above, it is not difficult to recall the previous PV. The erased symbols make it almost immediately clear whose engraving it is.

The bottom side represents the engraving effect, which varies and is available for selection.

Then came the battles, layer upon layer, against countless Honkai Beasts, mechs, and assassins. She also discovered that the imprint she had just received had made Mei much stronger.

In the ensuing battle, Mei also discovered that the only imprint she could accept was the broken purple crystal flower imprinted on the door.

[Mei, Paradise, Great Adventure! Yay, it's a great adventure!]

Wow~ she's so good at this, she's already starting to flirt?

[World-famous painting - Kiana in reverse entropy]

Did she introduce herself? Those lines... she's so good at it! She must be a bad woman!

"Hmm~ Is it finally my turn?"
