"This is the manga Boss was talking about?"
Yanfei stared curiously at the cover — a chubby blue creature, with no ears, that looked like a cat.
And it's fat too?
It seemed kind of silly, but also strangely fun.
She picked it up and quickly sat down to read.
Although she didn't fully understand the world inside, the bizarre gadgets left her constantly amazed.
"This thing called a Bamboo-Copter is insane! It can make you fly right into the air?"
"And this… Anywhere Door? It can open to any place? That's way too incredible!"
"Wait, you can even travel through time?! If only I had a Time Machine of my own…"
Every new gadget had her gasping in shock.
She could hardly imagine what Teyvat would be like if such items actually existed here.
"I wonder what Yanfei's reading. From the way she keeps blurting out those strange words, it seems really interesting…"
Hearing her, Xiangling's curiosity was burning.
She almost wanted to peek too.
But remembering Boss Han's rule — one manga per day — and her own obsession with food, she managed to suppress her urge.
Meanwhile, Lisa closed her book.
She had just finished Detective Conan, her eyes gleaming with surprise.
The sheer ingenuity of the murders inside was terrifying.
If Teyvat didn't have elemental powers and was just an ordinary world…
Lisa suspected this series might be hailed as a manual of classics by certain people or organizations.
The tricks were simply too many.
Polished well, some of them could very well create the perfect crime — one where the culprit could never be caught.
A must-have for travel, for neighborhood feuds, and for those with… darker hobbies.
But what truly caught her attention wasn't the crimes — it was the mysterious drug: APTX4869.
It could actually reverse a person's age, turning them back into a child!
The only problem was the mortality rate.
From what she saw, only Conan, Haibara Ai, and that young girl Kir were known to have survived.
As for Vermouth, the enigmatic woman… Lisa wasn't sure if she had taken it.
If only I could get a dose of APTX4869… I could study it carefully. Who knows, maybe I'd even manage to develop something from it.
The thought stirred excitement within her.
Right then, the system message refreshed:
[Customer Lisa finished reading Detective Conan. Reward: Complete data on APTX4869, plus one Perfect APTX4869 pill.]
[Complete Data: Compiled and organized by manga character Miyano Shiho.]
[Perfect APTX4869: Refined by the system. Has no side effects. Instantly reverts the user to childhood.]
"Tsk, tsk… complete research notes and the drug itself. That really is tailored perfectly for Lisa."
Han Feng's eyes gleamed with interest.
But would she even understand the data?
After all, this was knowledge from another world, an entirely different system from Teyvat's.
Still, Lisa was a once-in-centuries genius. She might actually unravel it.
If she succeeded… now that would be fascinating.
Because in a sense, this APTX4869 was a true elixir of immortality.
Han Feng's anticipation quietly grew.
Buzz—
A brilliant light descended, engulfing Lisa.
An enormous torrent of information flooded into her mind.
The spectacle immediately caught the attention of Xiangling and Yanfei.
"So this is the reward from reading manga?"
Seeing how calm the others in the shop looked, they quickly realized it must be.
And their curiosity only deepened.
What sort of prize would this beautiful sorceress get?
Moments later, the glow faded.
Lisa slowly opened her eyes, a spark of excitement flickering within them.
"Complete knowledge on APTX4869?"
Although many terms and formulas were foreign to her, with enough time, she was confident she could work through them.
"And this…"
She pinched the small pill in her hand, her gaze filled with curiosity.
This must be the legendary APTX4869.
But… did it have side effects?
Sensing her doubts, Han Feng spoke up:
"That pill is a perfected version of APTX4869. No side effects. Once you take it, you'll instantly return to childhood."
"What?!"
The entire shop was shaken.
"Turn back into a child? Isn't that… the legendary fountain of youth?!"
"Amazing… if I had one of these, I could just wait until I'm old, then eat it and live a whole new life!"
"Detective Conan, huh? No way — I'm definitely coming back tomorrow to read it."
The effect of APTX4869 was even more shocking than Han Feng expected.
It stirred immense curiosity and desire.
For most people, the allure of eternal youth was even greater than that of raw power.
"What a terrifyingly wondrous medicine…"
Dainsleif couldn't help but sigh.
He had lived for over five centuries already and had no need for it.
But for ordinary people, its temptation would be irresistible.
This Manga shop truly was unbelievable — even a drug like this could exist here.
His faith in the store grew stronger.
Perhaps… he really could find the reward he sought.
"Wait. That little girl just now mentioned a device that could travel through time?"
Dainsleif's heart skipped a beat.
If such a gadget really existed, it could change everything.
It would mean he could travel back five hundred years…
back to fallen Khaenri'ah.
The thought sent a wave of emotion through him.
Tomorrow, I must read that manga.
Of course, that also meant he now had several manga he needed to read, which would take more time.
"Well… looks like I'll be staying in Mondstadt for quite a while."
With that decision made, Dainsleif's eyes gleamed with determination.
