I'm doing Jujutsu Kaisen in the ninja world.

"...Are you sure? As the Mizukage, shouldn't this be your busiest time?"

"You don't want it anymore?"

"Hey, if you don't care, why should I be afraid? Let's go."

After changing into clean clothes, Mei Terumi and Shinji went outside and strolled in the rain, each holding an umbrella.

Shinji could tell that this woman was probably emo.

I had a lot to say but no one to talk to, so I asked him to come out for a walk.

Do you know what these so-called cursed spirits are all about?

"I know."

"you know?"

Mei Terumi hadn't expected a definite reply; she just wanted to use that question to start a conversation. But what a pleasant surprise!

"Yes, I know."

Mei Terumi took a deep breath. "Name your price."

Shinji smiled and said, "Fine, considering how many bargains you've given me, I'll tell you whatever you want to know today. Even if I don't know, I'll make up an answer for you."

He was telling the truth. If it weren't for Wuyin protecting him, he wouldn't have had such a great harvest.

In addition, he was still thinking about the hidden strength of the Hidden Mist Village, so he decided to be generous this time.

Mei Terumi had no idea about any of this and thought that this guy was only revealing it because he was "one of us," just like before.

"The so-called cursed spirits are actually creatures born from the negative emotions of humans such as fear and hatred towards various things. After their birth, the strength and abilities of cursed spirits vary, and their abilities are biased towards whatever they are born from."

"For example, the octopus head that has the ability to counter you is probably a cursed spirit born from humanity's fear of the sea. You can think of it as a manifestation of the sea, but not the kind of beautiful and desirable one."

"So you should understand how foolish it is to play in the water in front of the 'ocean'."

Shinji added a final, joking remark.

Mei Terumi suddenly realized something, and many things she couldn't understand before became clear.

The embodiment of the ocean—just thinking about it makes you realize how terrifying it must be.

"Then... what is a domain?"

"This is a bit difficult to explain to you. You can think of it as the ultimate power, an X-rank forbidden technique above S-rank ninjutsu. It creates a space that is absolutely advantageous to oneself, and within this space, all one's attacks are guaranteed to hit. You should have already experienced its specific power."

"This power is indeed terrifying."

Mei Terumi nodded, then asked, "And you? Why are you able to possess this power?"

Shinji seemed to have known she would ask this, so he smiled and said, "Maybe it's because I'm an anomaly? Just kidding. This kind of power isn't unique to cursed spirits. I already possessed this power long before cursed spirits appeared. Perhaps there are other people like me in many places."

"Oh, right. I call this power curse power, and also curse magic."

"I feel like you're just making up an answer for me right now." Mei Terumi glanced at him, not pressing the issue further.

Because the question itself is not important.

Currently, all countries, including the Land of Water, are making every effort to research cursed spirits and their new system of power.

This will be a revolution!

Those who possess this new power will undoubtedly be at the forefront of change!

Therefore, it is not important how Shinji acquired this power; what is important is his attitude and stance.

Mei Terumi only needs to know that he is on the side of humanity.

She then asked many more questions that had been bothering her. Shinji answered the common-sense questions he could, and glossed over the ones that were harder to answer, since no one knew whether what he said was true or false.

As for why he knew?

Mei Terumi tacitly refrained from asking.

"The rain seems to be getting heavier. Should we go back? I've answered so many of your questions for free, I'm really at a huge loss."

"No rush, come with me to a place, we'll be there soon."

Following Mei Terumi, the two of them arrived at a secret space hidden underground.

"here it is?"

"This is the top-secret research base of the Hidden Mist Village, and also where cursed artifacts are stored. I shouldn't have brought you here, but your previous answers made me realize that you might be the one who understands cursed spirits the most. Perhaps seeing the research here could be of some help, so I made an exception."

Before opening the door, Mei Terumi glanced at him again. "Don't say I didn't take care of you. After we enter the cursed item storage room, you can choose one cursed item as a thank you for answering those questions. Remember, you only have one chance to choose."

Upon hearing this, Shinji immediately became interested.

Cursed objects are extremely valuable to him, especially those suitable for his use, which are extremely rare and hard to come by.

Even a powerful cursed spirit like Tuogen didn't drop any cursed items for him, which made him inwardly complain.

However, the 3 Cursed Soul Points and 3 [Domain Fragments] he gained were already a fortune.

[Chapter 182, "On the Possibility of Reproduction Between Humans and Cursed Spirits" (Bonus Chapter 5)]

After following Mei Terumi into the base, Shinji discovered that the scene was somewhat different from what he had imagined.

Although it is located underground, it is clean and bright inside.

Many people were in a hurry, and when they saw Mei Terumi, the Mizukage, they only nodded to her before going about their own business.

"So, Orochimaru really is the outlier after all?"

Shinji's impression of the research labs in the Naruto world mainly comes from Orochimaru's dark and gloomy secret base.

Looking at it now, this is what a proper research base should look like.

He didn't even recognize many of the experimental devices, and couldn't guess what they were used for.

"What are your orders, Lord Mizukage? And who is this gentleman?"

The person in charge here is a flat-chested girl with thick glasses. She's young but already has a very small bust, so her future is limitless.

"This is Mr. Akagi, a specialist in curse and spirit studies whom I specially invited from outside. He knows everything about curses and spirits. However, Mr. Akagi is very busy, so if you have any questions, you'd better hurry."

An expert in the study of curses and spirits?

The flat-chested girl gently pushed up her glasses, a cold glint flashing in her eyes. "In that case, Mr. Akagi, please come with me. Our researchers need the help of an 'expert' like you."

Woman, is Lee Jae-gan some kind of demon?

Shinji stared wide-eyed at Mei Terumi. This woman, who exuded a seductive aura at all times, covered her sexy red lips and chuckled twice. Had she just sold him out like that?

No wonder he was so generous, even allowing him to choose for himself.

It turns out everything was arranged long ago.

Okay, let's take a look. Anyway, he's quite interested in these people's research topics.

Take, for example, this Mediterranean powerhouse; his research topic is the transplantation of cursed spirits.

Transplanting parts of the cursed spirit's organs into animals, or even grafting them onto plants.

Alternatively, one could transplant parts of plants or animals onto the cursed spirit and observe the effects.

Although most of his attempts failed, he successfully transplanted the chives onto a humanoid cursed spirit and achieved remarkable results.

With sufficient incantation power, this incantation spirit can grow 500 kilograms of chives every day when fully activated!

It truly achieved the goal of harvesting one crop and having another grow!

However, the downside is also obvious: nobody dares to eat it...

For now, it can only be used to feed chickens. As for whether it can form a new industrial chain, we need to observe it for a long time.

For example, there's that guy who specializes in researching the gender of cursed spirits, trying to find out the secrets of their reproduction.

Although he was great, he dedicated everything to scientific research.

But no matter how Shinji looked at him, he seemed like someone trying to scam research funding.

After he finishes explaining the basics about cursed spirits, this guy will most likely lose his job.

"Hmm? What do you research?"

Shinji asked a question out of curiosity as he watched the woman intently dissecting a living cursed spirit.

The woman, in her thirties, seemed to have a very good personality. She smiled, put down her scalpel, wiped her hands, and explained, "Based on my research, the formation of cursed objects... you know what cursed objects are, right?"

"Yes, I know."

Shinji almost rolled his eyes.

"There are many factors that influence the formation of cursed objects. Among them, the stronger the cursed spirit was in life, the stronger the power that remains in a certain organ or part after death, and the easier it is to condense into a cursed object."

"But this is not the only factor, because many weaker, or even much weaker, cursed spirits can also create cursed objects, although the effects may be relatively weaker, but it is not absolute."

Hearing this, Shinji was genuinely surprised; this woman seemed to have something special about her.

He became interested. "What other factors are there?"

"For example, I've found that the cursed objects born from the death of cursed spirits are usually a very important organ or part of the body. Cursed spirits that are good at fighting with their horns have a relatively high probability of their horns transforming into cursed objects after death."

"Therefore, I believe that ensuring the integrity of certain organs within the cursed spirit's body is one of the key factors in obtaining cursed artifacts!"

"Like this frog monster in front of us, its attack method is to shoot its tongue out at extremely high speed, with enough power to even pierce through iron plates. If it can condense a cursed object after it dies, it will most likely be this tongue, or something related to it."

"If this tongue is destroyed now, the chances of it forming a cursed object after death will be greatly reduced. Even if a cursed object does form, it will almost certainly not be related to this tongue."

Shinji listened attentively to the woman's research and found that what she said made some sense.

It seems I really need to be more careful in the future; I can't just ruin things for the other person so easily.

"So what are you doing now?"

“I’m intentionally guiding this frog monster, making it keep using its tongue to attack the steel plate above. I think the more times it uses it, the greater the chance of it forming a cursed object.”

I understand. With continuous washing away of magical energy, residual magical energy will inevitably remain over time, especially since it's so well preserved...

hiss!

Shinji felt like he had unlocked the secret to wealth!

But then I realized that I simply didn't have that much time or that many people to help him artificially cultivate cursed objects.
