Seeing the eager anticipation in Xianyun's eyes for the [Portable Game Console Blueprint], Luya handed her the complete set.
There were more than ten sheets in total, each describing the crafting process of a different component.
Once all the pieces illustrated across these thirty-odd pages were completed, assembly would be simple—and with that, a single [Portable Game Console] would be finished!
The crafting techniques depicted weren't those of modern electronic engineering, but rather a clever fusion of existing Teyvat technologies capable of achieving similar effects.
So, even without the scientific knowledge of Blue Star, Xianyun could quickly learn the process.
According to the system's notes, anyone who followed the blueprint diligently—no matter how inexperienced—could master the craft within a month.
For a master of mechanisms like Xianyun, however, three days would be enough to understand everything.
In other words, Luya could soon expect the first prototype of the [Portable Game Console]!
Once that happened, he could calculate production speed, hire workers, and begin mass manufacturing.
That way, the video game version of Yu-Gi-Oh! could spread across Teyvat—and with it would come in-game purchases, merchandise, and spin-offs, creating an entire new industry.
Just imagining it made Luya's heart race with excitement.
…
Xianyun accepted the [Portable Game Console Blueprint] from Luya and immediately began studying it.
After just one page, she furrowed her brow in puzzlement.
"What is this… and what does it do?"
"It's intricate, yet…"
She turned to the next page and found it equally sophisticated.
The parts seemed interconnected somehow, though the full picture would only become clear once assembled.
Even after glancing through only two pages, Xianyun could feel her mastery of mechanism arts advancing noticeably.
If she managed to fully comprehend all of this, she could hardly imagine how far her skills would soar.
Suddenly, she thought of Guizhong.
Though her friend's mechanical arts had advanced over the past millennium, they had long stagnated at ancient standards.
Now, with Luya's blueprints, Guizhong could surely refine her craft once again.
Having a rival of equal skill would make things all the more interesting.
Adjusting her red-rimmed glasses, Xianyun looked a little embarrassed as she carefully asked, "May I… study these blueprints together with Guizhong?"
She knew how precious they were and feared that sharing them without permission might anger Luya.
Luya, however, nodded without hesitation.
"Of course you can. Just make sure to finish building it quickly—so your master can see your results~"
To Luya, the sooner production began, the better.
That way, he could calculate the manufacturing cost of each [Portable Game Console] and set an appropriate price.
Xianyun, being an adeptus skilled in mechanism arts, had no shortage of minerals or materials.
There was nothing for Luya to worry about.
"Understood, Master! I'll start right away! I promise to deliver a finished product as soon as possible!"
Luya smiled and nodded.
Though hearing someone thousands of years older call him "Master" felt surreal, he was getting used to it.
…
Watching Ganyu happily working in the card shop and seeing her old friend Guizhong again, Xianyun felt content.
She had only come down the mountain to casually observe the Lantern Rite, yet this visit had brought many unexpected blessings.
Even her once withdrawn and lonely little qilin disciple had grown lively thanks to this young human—no longer showing a hint of isolation.
Xianyun was pleased.
Still, she thought of her other disciple, Shenhe, and wondered when that girl would open up and find joy like Ganyu.
Looking between the blueprint in her hands and the game machine she had played earlier, she pondered.
Traveling daily between Mt. Aocang and Liyue Harbor was troublesome.
After weighing her options, Xianyun decided—she would settle in Liyue Harbor instead of remaining a lonely hermit atop the mountains.
The mortal world didn't seem so bad.
She could enjoy good food, duel with others in Luya's shop, and live peacefully among people.
With her thousands of years of accumulated wealth, buying a house on Feiyun Slope would be trivial.
"Master, rest assured… I'll finish the items on this blueprint as quickly as possible! However, I'm still curious—what exactly are these devices for?"
Luya pointed toward the Duel Game Machine she had played earlier and explained, "It's that thing—but built according to this blueprint.
It'll be about two-thirds the size of Ganyu's hands put together."
Xianyun was stunned.
"What!? Something that small… with the same functions as that massive machine!?"
Having tried the Duel Game Machine herself, she knew how intricate and responsive it was—reacting instantly to player input.
It had left her in awe.
So the thought of compressing all that functionality into a handheld device utterly shocked her.
Luya didn't explain further.
He wanted her to focus on completing the [Portable Game Console] before introducing the next step—network integration and online play.
The [Network Communication Technology Tutorial] was still in his system inventory, untouched.
One thing at a time.
"Then, Master, this disciple shall take her leave."
Luya nodded, and Xianyun departed.
…
Next on Luya's list—earn more money!
He needed funds to upgrade his skills, his shop, open branches, and eventually expand to other nations.
At the moment, business was slow.
Customers like Hu Tao, Keqing, and Xingqiu—those with money to spare—had yet to arrive.
So he decided to postpone the auction of the 30-million-Mora [Random Theme Starter Deck].
Speaking of decks, Luya suddenly remembered—he had forgotten to give Ganyu her gift!
He retrieved the [Random Theme Starter Deck] from his system inventory and handed it to her.
It was a finely packaged deck box, marked with a question mark.
"This is an employee benefit—for being my first staff member. I'm giving you this deck."
Hearing that, Ganyu was overjoyed, setting aside her work with a blush.
"Thank you, Shopkeeper!" she said shyly.
She had always been interested in dueling but lacked her own Deck, so this gift delighted her.
She eagerly opened the [Random Theme Starter Deck].
A radiant light burst forth!
A dragon spirit covered in wooden scales materialized in the shop.
Luya recognized it immediately—
[Naturia Barkion] EARTH│Level 6│Dragon│2500 ATK / 1800 DEF
Materials: EARTH Tuner + 1 or more non-Tuner EARTH monsters
Effect: When a Trap Card is activated: You can banish 2 cards from your Graveyard; negate the activation, and if you do, destroy it.
"So it seems this Theme Deck… instantly grants a full random Yu-Gi-Oh! Deck."
Ganyu's was a [Naturia] Deck, including Fusion and Synchro Monsters.
Many of the monsters were modeled after plants and animals—cute and full of life.
Cards like [Naturia Cherry], [Naturia Pumpkin], and [Naturia Mantis].
They suited Ganyu perfectly, who had lived surrounded by flora and fauna in Mt. Aocang.
Long ago, when she used to watch the clouds there, she had a companion—a snow leopard.
Yet as time passed and mortal lifespans waned, her animal friend was no exception.
Later, Cloud Retainer and the other adepti, wishing to commemorate it, created a dish called [Cheese Snow Leopard].
To this day, Ganyu still remembered its flavor—rich and fragrant.
The apparition of [Naturia Barkion] instantly drew attention from the surrounding crowd.
"What's going on!?"
"What dragon is that!?"
"What happened just now…?"
"It looks like the shopkeeper gave Miss Ganyu a Deck, and when she opened it—"
"That vision appeared!"
"My goodness!!! Did the shopkeeper release a new product!?"
