I'm doing Jujutsu Kaisen in the ninja world.

Shinji immediately led them to the black box on the table and explained, "See this handprint on the box? Just press your hand on it and then input chakra into it. It's a foolproof operation; even ninja academy students can do it."

"As for your concerns, they simply don't exist! If you have any health problems, you can come to me anytime. That's the Hokage Building over there. I'd be too old to lie to you."

Upon hearing this, Tsuchida Hisao and the other two realized that this was indeed the case, but they still hesitated in the face of the unknown.

Seeing the group looking at each other, their hearts pounding yet their minds in turmoil, Shinji simply added fuel to the fire.

"So, today is the first day of our business, and the first customer's fee will be doubled, which is 200,000 taels. But in return, we'll need the customer to help spread the word, is that alright?"

Wow, they doubled the price without warning?!

"I'll do it!"

Before his companions could react, Hisao Tsuchida placed his hand directly on the box.

"I'm sorry, but the chance to double your money only comes once."

The other two, though somewhat disappointed, were not about to turn against each other over 100,000 taels of silver; instead, they watched nervously from the sidelines.

The chakra input was extremely fast, taking less than a minute, before Shinji called for a stop.

"The guest's chakra is fire-attribute. Here is 200,000 ryo. Please check and keep it safe. Next!"

Tsuchida Hisao checked his chakra and found that he still had about half of it left. He had already earned 200,000 ryo? That was too easy money!

He was still in a daze when his two companions had sold all their chakra and received 100,000 ryo.

"Hisao, let's go! What are you spacing out for!"

"Hahaha, we really made a fortune today. But Jiu Xiong, you got 200,000 taels, shouldn't you treat us?"

Tsuchida Hisao snapped out of his daze and quickly said, "Absolutely! I'll pay today, we won't leave until we're drunk!"

The experience was so surreal that they felt a little unsteady on their feet as they left.

At this moment, Shinji also showed a satisfied smile on his face.

The black box actually contained a modification scroll, which was used to deceive people.

The handprint groove on top is so that visitors can touch the contents inside, thus successfully 'recovering' chakra.

As for the reason he called a halt, it was based on the progress bar, and he tried to keep it at around one percent each time.

In this way, it would take about a hundred repetitions to fully charge one type of chakra.

He did this to build a reputation and create a buzz, otherwise he was afraid that he would have collected all the other types of chakra, but the Yin and Yang attributes would still be untouched.

As long as enough people come to him to sell chakra, he doesn't believe those guys who have mastered the secret techniques of Yin-Yang chakra nature transformation won't be tempted.

"Excuse me... is what's written on the sign at the entrance true?"

"Of course, 100% innocent. What is the chakra attribute of the guest?"

"Wind attribute".

"Please come in, please come in."

Shinji's smile became increasingly sinister.

. . . . . . .

As if overnight, a place called "Chakra Shop" suddenly became popular.

The reason, of course, is that those customers who had already tasted the benefits quickly shared this great place for getting freebies with their friends, classmates, and even teachers.

Even if someone has a dark side and doesn't want others to share it, it's no use.

Because if even one-tenth of the people are willing to promote it, it will quickly become known to everyone.

Shinji then found himself suddenly very busy.

"What attribute?"

"fire."

"Here's your 100,000 taels. Next person."

"No need to ask, I'm also a fire elementalist."

"...good."

"Here's your 100,000 taels. Next person."

"Um, I feel like I still have a lot of chakra left, can I sell it one more time?"

"Sorry, but to be fair, each person can only sell chakra once a day. This is also for everyone's safety. After all, if you encounter an emergency and find yourself out of chakra, and then get killed by the enemy, how frustrating would that be?"

This reason is quite plausible and has garnered considerable approval.

Some people who were always looking for bargains had no choice but to give up their ideas when they saw this situation. They patiently lined up and prepared to come every day, determined to stick with this store.

You said you can only sell once a day, so can I come every day?

Shinji can't prevent this kind of thing, nor does he care. All he wants is chakra, and it doesn't matter whether that chakra comes from a hundred people or ten people.

He's not really here to give Konoha ninjas any benefits.

However, as the number of guests increased, Shinji began to have a headache, because he found that most of the people who came were fire-attribute, which is the same concept as the fact that most of the ninjas in Kirigakure are water-attribute.

But there are other chakra natures as well, let's take it one step at a time.

"What attribute?"

"earth..."

"Okay, put your hands up here."

"Ah."

Shinji was busy and hadn't paid attention to who the visitor was, but the progress bar of the modification scroll suddenly caught his attention.

"Why is it that, apart from earth, both yin and yang are rising?"

Shinji paused for a moment, then quickly looked at the little girl in front of him; she looked somewhat familiar...

"Are you from a mountain tribe?"

"Huh? How did you know?"

"Oh, I know a guy named Yamanaka Fu, we've been on missions together."

"You're Uncle Feng's friend? My name is Ino, Yamanaka Ino."

really...

"Okay, that's enough."

Seeing that she was already swaying precariously, Shinji quickly called for a stop.

Although the quantity is insufficient, the quality is high.

Ino possesses the attributes of earth, yin, and yang simultaneously, oh right, and water as well.

The water tank is already full, so it lights up when you input, but doesn't show an increase.

[192. Chapter 187 Don't Try to Guess a Girl's Thoughts]

Shinji glanced at the numbers displayed on the progress bar and felt a little disappointed.

Ino's chakra attributes are exactly what he needs, but the amount is too small.

but...

Shinji suddenly thought of a solution.

"Alright, here's 20 taels. Please accept it."

"20 taels? That..."

Upon hearing this number, Ino felt both happy and conflicted.

"what happened?"

"Earth attribute...isn't it 10 taels? Shopkeeper, you don't need to give me special treatment just because of Uncle Feng."

Ino was a little embarrassed; after all, she was still a little girl and easily embarrassed.

Shinji's smile froze on his face.

Store manager...uncle?

His eyes suddenly turned dangerous. "Just call me brother. Actually, I'm not very familiar with your Uncle Feng. We've only met once. I won't take special care of you because of him."

"I'm giving you this 20 taels because your chakra attributes include Yin in addition to Earth, which is why it's priced this way. Take it without worry."

Ino, who had only recently graduated, didn't know much about this area. Upon hearing this, she immediately understood and was overjoyed!

"This is great! Not only can I buy that dress and show it off to Sakura, but I can also use the remaining money to help my mom with household expenses. Mom will be so happy."

Ino happily and carefully put the money away.

He was still wondering what Sakura's expression would be like then.

"By the way, Ino... can I ask you for a favor?"

Just before Ino was leaving, Shinji suddenly called out to her.

"What's wrong, store manager...brother?"

Upon seeing someone's suddenly terrifying expression, Ino instantly changed her mind, almost breaking out in a cold sweat.

"Oh, it's like this, our store has only just opened and we need some promotion. If any of your teachers or classmates need this kind of help, you can recommend it to us."

Upon hearing that it was such a small matter, Ino's heart, which had been in her throat, immediately settled back into her stomach. She patted her chest, which was barely rising and falling, and assured her, "Absolutely no problem, I will definitely help...big brother promote it well."

Shinji, whose expression shifted from terrifying to a friendly smile, nodded and said with a grin, "Then thank you."

After saying goodbye, Ino quickly ran out.

Although the shop manager was quite handsome and didn't look that old, Ino didn't find him to be her type, and he was at least several years older than her!

If she weren't indebted to him, she definitely wouldn't have called him "brother."

Sasuke is definitely the coolest, so cool it's breathtaking!

Ino gushed over her crush for a while, then promptly went shopping.
