Becoming a Gadget Master Starting from Hunter x Hunter

"7" □□

Here's a way.

Morin smiled and rejected Biscuit's "kind offer," as well as the help Pakunoda offered:

"I have a way."

"What way? You know you need to dedicate all your focus to training right now. You can't let earning money distract you," Biscuit warned.

"Of course. Nen training will always be my top priority," Morin said genuinely, happy.

"It's just that I got a new item these past two days."

"A new item?" Biscuit looked enlightened yet curious. "What is it?"

The only thing that could give Morin such confidence was his collection of strange, peculiar items, whose effects always made her envious.

"This item is called the [Compound Interest Bank]."

Morin produced an item that looked like a yellow bank counter with two windows labeled [Deposit] and [Borrow].

"[Compound Interest Bank]? Is it an item related to savings interest?" Biscuit examined the bank, "It doesn't look particularly special, but since it's an item, it must have some effect, right? What does it do? Can you deposit and withdraw money anytime, anywhere, or does it offer higher interest than normal banks?"

Biscuit's experience was vast, and she immediately listed the functions of a bank.

"It does all those things you mentioned, and it's even more powerful," Morin said, picking up his ten Jewel coin and placing it at the [Deposit] window.

The coin was automatically sucked in, and the bank emitted a robotic voice:

"Thank you for using the Compound Interest Bank. We appreciate your patronage."

As it spoke, it spat out Morin's savings passbook.

Seeing this, Biscuit marveled again, feeling her horizons broadened. "You really have everything under the sun. Having you around is like being with an all-purpose robot; any request can be fulfilled."

She then took the passbook, flipped to the page for the ten Jewel deposit, and casually asked, "How much interest does this portable bank offer?"

In her mind, even if it was higher than a normal bank, it wouldn't be by much. Its greatest benefit was its portability.

"It's the Compound Interest Bank," Morin corrected. "Its interest rate is ten percent per hour."

Item: Compound Interest Bank. Effect: A bank with [Deposit] and [Borrow] windows. Deposits earn ten percent interest per hour, leading to abundant wealth. Borrowing incurs twenty percent interest per hour, compounding until the loan is repaid. Failure to repay quickly will result in misfortune.

"Ten percent interest per hour?" Biscuit thought for a moment, calculating rapidly. "How much is that?"

"Take my deposit of 10 Jewels, for example. After one hour, it becomes 11 Jewels. After two hours, 12.1 Jewels. After three hours, 13.31 Jewels. In eight hours, it will double. In a day, it will be 100 Jewels," Morin calculated for her.

"Only a hundred Jewels a day," Biscuit pouted, losing interest.

Clearly, her master might be capable in other areas, but he was completely insensitive when it came to math or numbers.

Morin thought this.

Even though it was only a small hundred Jewels, it was derived from 10 Jewels doubling! In just one day, it had increased tenfold! What if he deposited a hundred Jewels? A thousand? Or even ten thousand?! What bank outside could offer such high interest?!

Morin sometimes wondered if an item like this from Doraemon's world wouldn't cause economic and financial collapse, leading to hyperinflation and the complete breakdown of the monetary system?

"How long do you plan to leave those ten Jewels deposited?" Biscuit asked lazily from her bed, teasing.

"I plan to leave it for about a week."

Morin said, putting the savings passbook away first.

As for the Compound Interest Bank, he set it aside for now, because it might be needed again soon.

"A week? How much money would that be?" Biscuit asked casually, flipping her blonde ponytail.

"If you deposit for a week, it's not much, only about ninety million Jewel," Morin replied, pretending to be casual and lighthearted.

"Oh?" Biscuit nodded subconsciously. "Only ninety million Jewel... Wait?!!!"

Thump!!

She unceremoniously fell off the bed.

"H-how much?!" Scrambling up from the floor, she completely disregarded her image, her voice sharp.

Pakunoda, who was equally shocked by the figure, covered her ears.

"Ninety million Jewel," Morin repeated, also covering his ears.

"Ninety million... in just one week????" Biscuit stared, dumbfounded. "You're openly robbing people!!!"

"No!!!" she exclaimed, shaking her head frantically. "This is even faster than robbing!"

"Um..." She looked at Morin, her expression unusually serious. "Are you kidding me?"

"What do you think?" Morin asked with a smile.

"I don't think so either," Biscuit said, holding her forehead. "So you really manifested an incredible item!!"

Although Biscuit wasn't good at math, she clearly understood the impact and influence such a large amount of money would have on the world!

"This thing is no less powerful than the large-scale weapons of mass destruction the V5 possesses, perhaps even more so." Biscuit looked at Morin with a complex expression. Her young disciple truly never ceased to surprise her in unimaginable ways.

"This must absolutely not be known by anyone else!" Biscuit said seriously, emphasizing her words. "And it absolutely cannot be lent to anyone else to use!!"

"It's enough for just the three of us to know!!" If outsiders knew they had such a divine artifact for making money, the entire world would go mad. Who knew how many countless experts would come after them – wild ones, those specifically raised by the V5, and many civilian organizations, etc. They wouldn't have a moment's peace for the rest of their lives.

"Can we tell Machi about this item?" Pakunoda suddenly asked, having been silent until now.

"Who's Machi?" Biscuit asked.

"A friend of mine who is very good with money and likes it a lot," Morin offered a relatively neutral assessment.

"No!" Biscuit shook her head. "Let alone friends, even parents and family can't know!!"

"I don't have parents or family," Morin said with a casual smile. "I wasn't planning on telling Machi anyway. With her personality, she'd definitely deposit all her money with me, and I'd be annoyed to death. This is a secret between the three of us."

Hearing this, Biscuit's expression softened slightly as she nodded. She then tapped Morin's head, "What are you saying? Isn't your master family?"

"Didn't you tell me not to call you Master?"

"Oh, so you think you're rich now, your wings have grown strong, or you think you've learned enough skills and don't need me anymore? You don't want to acknowledge me as your Master anymore?"

"What are you even talking about?! I do, I do."

Watching Morin and Biscuit, who seemed to be putting on an act, bicker, Pakunoda, having gotten the answer she wanted, let a slight smile grace her lips.

"A secret that belongs to us?"

Although she came from Meteor City, she shouldn't have possessed particularly complex emotions.

However, when she was with Morin, she truly felt relaxed and happy.

It was just like what the books described... the warmth of home.

And because Morin was the one she had picked up and lived with, spending the most time with Morin, and the one who meant the most to Machi?

Pakunoda would also occasionally feel a different kind of emotion arise.

But in her opinion, it was enough that she, Pakunoda, was the one staying with Morin right now.

And just as Pakunoda was lost in thought, Morin and Biscuit stopped their playful fighting.

"Speaking of which,"

Biscuit's tone suddenly softened.

"Since this Gadget is destined to be known only by the three of us, why don't we use it too, hmm?"

She said with great affection, her eyes like water, still shamelessly flirting.

"My good disciple~"

Her voice was alluring to the bone, her breath like orchid fragrance, and hearing it would give anyone goosebumps.

If it were any other normal man, under her onslaught, they would immediately surrender, their bones going soft by half.
