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

"I understand the law," the one who knew the law said smugly, then, watching the other person grind their teeth, a blush appeared on his face—he was furious.

She sensed that the other person had an urge to bite her, so she decided to strike first.

"Hold on, hold on. Haven't you been wondering where I went the other day? Although I was a little incredulous when I came back, it's absolutely true that I watched you fight~"

The one who understood the law said with a chuckle,

"Looking?"

Theresa and Fu Hua exchanged a glance, then turned to look at her with a puzzled expression.

"Speaking of which, Otto has something to say to you in the end—heh heh, Theresa, eat some fruits and vegetables other than bitter melon once in a while."

The Herrscher of Knowledge looked at Theresa, her eyes darting around as she remembered something amusing.

She coughed twice, cleared her throat, and spoke in a heavy, mournful voice, mimicking someone from her memory.

"...You always stay up late, your body needs more nutrition."

"..."

Theresa pursed her lips, looking at the other person with suspicion.

This tone doesn't sound like something her grandfather would say.

"Hmm... You don't believe me? Let me think—Theresa, that cooking magic of love has worn off, so take good care of yourself~"

"...Okay, I believe you,"

Theresa was initially startled, feeling as if her dark past had been discovered.

Then I realized that it happened a very, very long time ago, so long that her students couldn't possibly know about it. The most likely person to know was actually the person who experienced the event firsthand—her grandfather.

"So... you went to a higher dimension and observed everything in this world, as well as Otto... Grandpa's footsteps?"

Theresa spoke hesitantly, but then her expression changed as she observed the other person's demeanor.

"Hehe—although I don't think it resembles any higher-dimensional world at all, even I have changed my opinion of Otto when he finally took that step,"

"Rather than going to a higher dimension, it's more accurate to say that he witnessed the formation of the dual world. His saintess survived that destined death."

"It is the law of knowledge," the one who understands said softly.

With a casual flick of her right hand, a fishing rod appeared in her grasp. She cast the line straight into the river below, causing ripples to spread across the still water.

As for whether there are fish?

She simply felt the scenery here was so beautiful that she couldn't fulfill her wish without casting a line.

"...Did he succeed? Heh, no wonder, after all, he's Grandpa. What he wanted to do, he's never failed?"

Theresa was taken aback, and the worry that had been weighing on her heart instantly subsided.

Although she didn't show it on the surface, a secret joy welled up deep inside her. Sure enough, if it didn't concern the fate of so many people, she would still hope that the other party could get what they wanted.

"Hehe—well, that's hard to say. Anyway, I think Otto's early life was pretty unsuccessful. Never mind, let's not talk about it anymore; let bygones be bygones."

The man of knowledge, gazing impatiently at the still water, jerked his fishing rod forcefully.

"Sigh, what Li Sushang said makes a lot of sense. When it comes to life, you have to focus on the present. Look at that old man, he was thinking of saving his strength to help Kiana later, but he ended up losing that duel instead."

Seeing that he had been fishing for a full three minutes without getting a bite, the Knower of Law simply tossed the conjured fishing rod aside.

He turned to Fu Hua beside him and said, with a hint of disappointment in his voice.

"Tsk, what a pity. I'll have to fight her again sooner or later, otherwise my combat ranking will drop a little further. Old timer, give me a break."

"Uh... combat power, ranking?"

Having not paid attention to what was said before about the Herrscher of Knowledge, Fu Hua reached up to adjust her glasses, frowning as she looked at the other person. She was somewhat confused by the term.

"Hey, look, you and Kiana beat me, and then you lost to Su Chang. Now I have to prove that I'm better than Su Chang! Otherwise, how can I convince everyone?"

Those who understood the principles of law, however, refuted this with great conviction,

Forget about the old-fashioned character; Kiana is also a main character, and the two of them together defeated her. That's a good result.

But that junior can't possibly try to ride roughshod over her! She'll have to ask her all eighteen weapons if she'll allow it!

"Haha, Herrscher of Knowledge, your thought process jumps around so fast, I can't keep up with you..."

Theresa rubbed her temples, feeling a deep headache. At first, the other person's words sounded plausible, but what was that all about?

Can't you be a little more serious?

Even the gentle breeze that was originally pleasant has now become somewhat irritating.

She was overwhelmed by the amount of knowledge she had acquired at once, and didn't quite grasp it all at first. But the familiar language indicated that she had clearly understood the development of this world.

The other party was not lying about this point.

"...Sigh, the Herald of Knowledge? I'm actually getting a little used to that title now. Tsk, habit really can change a person."

The one who understood the law felt inexplicably disappointed.

She actually missed the atmosphere of that other world, otherwise she wouldn't have gone to Mount Taixu first after returning, ignoring everyone, hoping for some peace and quiet. But... she simply couldn't stand that environment anymore.

So I came back, but... after coming into contact with both sides, I found that things had really changed a lot.
