Kai had a great idea.
Who was standing before him at this moment?
The main characters?
No, they were tool-persons!
For Kai, there wasn't much difference between main characters and tool-persons.
After all, according to normal plot development, main characters are meant to be used as tool-persons.
From finding lost pet cats to soloing dragons, a series of incredible tasks could be entrusted to the main characters.
Even if you were a heinous villain, as long as you came up with a plausible reason, the main characters would meticulously undertake it.
This behavior seemed not much different from a tool-person who goes wherever they are needed.
Especially these two main characters in the world of Teyvat.
If Lumine still had some thinking ability, then by just tricking the smaller one next to her, almost anything could be achieved.
"Wow~ A hero protecting Mondstadt?"
Indeed, facing Kai's unreserved admission, little Paimon immediately floated over.
She made a very large gesture with her hands, her adorable face full of admiration.
She didn't have a shred of doubt.
"I saw that whole scene just now."
"You actually wiped out so many Hilichurl in one go."
"As expected of a hero protecting Mondstadt."
Hmm, this smaller one is easier to fool.
Kai nodded as a matter of course, maintaining a friendly smile on his face.
"I just wonder… can you teach me that move from earlier?"
After saying her compliments, Paimon stared at Kai with incredibly hopeful eyes.
She finally revealed her true thoughts.
"I want to become that powerful too."
"Then I'll go rob dragons… ah, no, I mean protect Mondstadt!"
You meant to say "rob dragons," didn't you?
Kai glanced at her tiny body, which wasn't even enough to be a dragon's snack.
However, this kind of request was completely within his expectations.
Although a long time had passed, Kai still clearly remembered his general impression of Paimon from deep within his memories.
Her personality was entirely… without any surprises.
"Hmm… this matter isn't impossible to consider."
"Eh?"
She seemed not to have expected that this very powerful-looking person named Kai would agree so easily.
Paimon floated, her adorable expression full of surprise.
After all, Paimon had witnessed that move from start to finish.
It was a cool move that could summon various weapons from the sky, wiping out a pile of Hilichurl in minutes, powerful beyond words.
If she could learn it, she could probably walk sideways across the entire continent of Teyvat, couldn't she?
She imagined countless treasures guarded by monsters, all waiting for her to unearth.
Ancient small towns suffering monster attacks, with her, the hero, making a cool entrance and eliminating all enemies with one move.
From then on, living a life of comfort and abundance under the adoration of the people.
Paimon chuckled, almost drooling.
"Then, then…"
"But before Facing Paimon, who had completely fallen for his trick, Master Kai's eyes flashed with a hint of slyness.
Without rushing, he slowly spoke the rest of his intentions.
"You have to do me a favor."
"What favor?"
With the dream of a life free from worry about food and clothing, Paimon had completely forgotten everything else.
She flew directly in front of Kai without any guard.
She quickly nodded her small head.
"Hmm, actually, it's a small matter."
Pointing to the messy Starfell Lake around them, Kai replied calmly.
"You two eliminated these Hilichurl, understood?"
"Us..."
Seeing Paimon's unchanging small eyes, Kai knew that she definitely didn't understand.
So, he then turned his gaze to Lumine.
Sure enough, as the legitimate protagonist, Lumine's reaction speed was infinitely better than Paimon's.
Facing Kai's request, she couldn't help but show a questioning look.
"Why is that?"
"Because Paimon said before that I am a hero who secretly protects Mondstadt."
"So, I don't want to reveal my identity for now, can you understand that?"
This was, of course, Kai's serious nonsense.
The main reason, in fact, was because of Jean.
It's not that Kai had hidden anything from Jean...
In fact, Jean knew a little about Kai's affairs.
For example, she knew that Kai had some investments outside, so he was relatively well-off.
She also knew that Kai was extremely strong.
Especially in swordsmanship, he was by no means inferior to her, the Dandelion Knight.
But the problem was... she didn't know about what he was doing!
In Jean's impression, although Kai possessed swordsmanship that could suppress the entire Knights of Favonius, due to his relatively peaceful personality, he rarely fought with others.
Coupled with the fact that he was her husband, Jean had never suspected Kai even when mysterious person cases occasionally occurred in the city.
But in fact, over these years, for various reasons, Kai had secretly done a lot of things.
For example, the most recent time.
He suddenly jumped down from the city wall in the middle of the night.
He used his holy fist to punish.
He beat several Snezhnaya envoys, who had been arrogant and aggressive in the Knights of Favonius Headquarters during the day, half to death.
Although it felt good.
But no matter what, most of these actions violated the regulations of Mondstadt City.
Even in the internal archives of the Knights of Favonius.
Several cases were recorded, all related to a mysterious person who could use strange abilities.
But whose identity was unknown.
In this situation... if you let Jean discover that her usually peaceful husband.
Would secretly sneak out of the city, completely wipe out the Hilichurl at Starfell Lake in one go, and the abilities he used.
Were also very similar to a certain mysterious person with a long criminal record in the Knights of Favonius archives.
With his wife's intelligence and connecting it to past events.
Uh... Kai mused, after returning home.
This matter would really be a big deal!
"So that's how it is, hehe, I understand, I understand ~"
Lumine was still thinking seriously.
But Paimon beside her, hearing that it was only this request.
Almost immediately nodded and agreed.
With an expression like she had gotten a bargain.
"In any case, I will definitely help Master Kai keep this secret!"
"And what we agreed upon earlier..."
"No rush, I need some time to rest, right?"
Kai waved his hand, replying calmly.
"Such a powerful move consumes a lot of stamina; I'll teach you after I've adjusted my physical condition."
"Also, Mondstadt City is just north of here, I have something to do, so I'll be leaving first."
"Goodbye!"
Kai rattled off a bunch of words, giving Paimon no chance to react.
After speaking, he turned and ran towards Mondstadt City.
His figure disappeared from their sight in the blink of an eye.
"So... so fast!"
Paimon opened her small mouth, looking at Kai, who had completely disappeared.
Her face was almost filled with horror.
Even his running speed was so terrifying?
He truly is the hero who protects Mondstadt.
"He's really amazing!"
Paimon's small eyes sparkled with anticipation.
Lumine, however, beside her.
Looking at the messy Starfell Lake and Kai's receding figure.
Her expression became slightly unnatural.
"It seems... something isn't quite right."
Her intuition probably told her so!
