Chapter 86 Foolish Beauty

There are many ways to heat up a bento box.

Microwave heating is considered a form of lightning-based energy manipulation.

Vibration heating is a type of wind escape.

However, Ning Yuan did not know whether Xi Ri Hong possessed these two attributes.

Kurenai Yuhi learned genjutsu from her father from a young age and had basically never been exposed to other elemental ninjutsu.

She is also not suited to learning elemental ninjutsu, not because she is stupid and cannot learn it, but because she has too little chakra.

She only has 4 chakra, while Kakashi, whose chakra is limited by the Sharingan and who has to lie down after releasing just a few ninjutsu, has 6!

What does that mean?

In short, after Kurenai Yuhi reached adulthood, her chakra was basically exhausted after releasing an A-rank Water Dragon Bullet.

This also shows that genjutsu is actually a type of ninjutsu that doesn't consume much chakra, yet its power is astonishing.

This is a typical example of a cost-effective ninjutsu.

Ning Yuan certainly wouldn't show off the techniques that Yuhi Hong couldn't learn, probably because he was afraid his girlfriend would be too friendly towards him.

Therefore, he used a non-elemental ninjutsu.

That is: the power of pure chakra.

Chakra is also a form of energy. When one type of energy is injected into another object, the energy level of that object will naturally increase, which will manifest as an increase in temperature in the external environment.

However, this is not an easy task, because rice is not a chakra metal and cannot contain chakra at all.

But water is possible, otherwise how would ninjas walk on water?

It's not easy to raise the temperature of a basin of water, but if it's just crystal water from food, you only need a little bit of chakra to raise its temperature.

"I call this the Chakra Intrusion Technique. The principle is to create a chakra area the size of a bento box, then refine the chakra and infiltrate the water molecules within the bento. Once the water heats up, it naturally heats the bento!" Ning Yuan explained. "And it's even a no-seal ninjutsu!"

"Amazing!" Kurenai Yuhi stared at Ning Yuan with her red eyes, looking at him with admiration, just like Ling Lingqi's wife looked at Ling Lingqi.

"Ahem, but this technique isn't easy to learn. How about we start with the basics!" Ning Yuan handed Kurenai a ring-shaped piece of paper: "Here's a paper wristband for you. Stick it on your wrist and cover it with chakra every day."

"This paper," Kurenai Yuhi said, taking the soft, rubber-band-like piece of paper with curiosity. "Is this paper? It looks so soft."

"Of course it's paper, but if it's not soft, it'll definitely be uncomfortable to stick to your skin!" Ning Yuan laughed. "Besides, regular paper doesn't last long; it'll break after a little bit of force or a short shower!"

"This paper is not only elastic, but also waterproof and very durable!"

"Furthermore, this paper is absolutely incompatible with chakra, but it has many tiny, invisible gaps. If you soak this paper with chakra over a long period, your chakra will gradually get used to flowing through these tiny gaps. In about two months, your chakra will adapt to this feeling. Then, when you soak the bento with chakra, the bento can be heated!"

"Is it that simple?" Kurenai Yuhi was somewhat surprised. In the past, learning an illusion technique was extremely difficult, and there was no guarantee that one could even learn it.

This so-called Chakra Intrusion Technique doesn't seem to require any action; all it takes is soaking the paper.

"It's that simple. How difficult could it be to heat up a bento box?" Ning Yuan laughed.

That being said, the technology behind this paper is actually quite sophisticated.

It's a thin sheet of paper, but it's actually seven sheets combined into one.

The gaps on these seven sheets of paper are not the same; they become increasingly finer from top to bottom.

In other words, Kurenai Yuhi's chakra control can be improved seven times once she clears this bracer!

However, this improvement is gradual and subtle, and Kurenai Yuhi has a small amount of chakra, which is easy to control, so she may not feel anything.

She may only discover her talent in chakra control when she encounters a situation that requires it.

However, by then this wristband will have long since completed its historical mission, and Kurenai Yuhi might have even forgotten about it.

In addition, this paper is also imbued with Ningyuan's chakra, which can be used to monitor Kurenai Yuhi's pulse. Since the pulse rate is the same as the heart rate, this wristband can also be used to monitor Kurenai Yuhi's heart rate.

He knew exactly what Kurenai did and when every day, and if her heart suddenly started racing at an abnormal rate at a certain point in time, it meant she was in danger.

Ningyuan can discover it immediately.

Kurenai Yuhi is no longer the daughter-in-law of the Sarutobi family, so Hiruzen Sarutobi will no longer protect her, and Danzo may then target her.

Although she was from a Jonin family and the chances of her dying were slim, Danzo cared about that.

Kurenai curiously put the wristband on her small arm, looking quite fond of it.

This wristband is not only useful, but also very stylish, featuring a cute chibi version of Kurenai Yuhi.

"By the way, are we going to have a practical training session this afternoon?" Ning Yuan asked.

"Yeah!" Kurenai Yuhi nodded, though her tone didn't seem particularly expectant.

There might only be one girl who likes this kind of course.

"I probably can't go!" Ning Yuan said, "The Hokage has arranged for me to take a medical ninjutsu class!"

He had already looked at the schedule; the course was held every afternoon.

It wasn't that Ning Yuan was being specifically targeted for not being allowed to take practical lessons; rather, the knowledge of medical ninjutsu was so vast that even three to five years of full-time classes wouldn't be enough to memorize it all.

"Huh?" Kurenai was taken aback. Her excited expression upon receiving the gift vanished immediately, and she grabbed Ning Yuan's hand.

"Can't we not go?" She didn't want the boy she liked to leave her side.

Being together every day is the best!

"It's the Hokage's decision, how could I dare not go!" Ning Yuan shrugged.

"Fine!" Kurenai Yuhi said helplessly.

"So I wanted to ask you, would you like to come with me to the medical ninjutsu class?" Ning Yuan asked.

"Ah, can I go too?" Kurenai Yuhi asked, her face filled with surprise and excitement.

She might not have the slightest interest in medical ninjutsu, but if she could accompany Ning Yuan, then of course there would be no problem!

"Of course!" Ning Yuan nodded. "I'm a genius, you know, I have a lot of influence!"

If he's right, then this "Medical Ninjutsu" class is what Hiruzen Sarutobi used to ruin Zhong Yong's future, meaning Ning Yuan has no choice but to attend.

Since it's a class that Ning Yuan has to attend, what's wrong with him bringing his girlfriend?

Hiruzen Sarutobi even wished he would have a girlfriend so he could be in love all the time and not be able to focus on his studies.

As for whether taking Kurenai Yuhi to medical ninjutsu classes will affect her growth in strength.

To put it another way, Kurenai Yuhi is different from others; she doesn't need to waste time on practical training.

Whether she goes or not, she's still that silly beauty who pokes the weasel with a kunai.
