In the 54th year of Konoha (this book is based on the 48th year of Naruto's birth in Konoha), on January 10th, a full week has passed since Yiyong officially began to cultivate the breath of fire. There are still 50 days left before the start of the ninja school.

In the mountain stream of the Nanga River, Yi Yong took off his shirt, and his immature body was like red and hot lava, motionless under the washing of the waterfall, allowing the cold water and hot body to touch each other, and rising up one after another hazy mist that can only be found in the bathroom.

Experience has proven that cultivating the opposite phase of Flame Breath in this place where the water breathing efficiency is extremely high can effectively weaken the vitality of the latter's extremely violent natural energy flowing through the body.

At present, Yi Yong has been able to initially adapt to the concentrated transformation of the body, especially the bones and muscle tissues by the breath of inflammation.

It is the feeling of burning an iron embryo in a flame, smelting it, and then forging and shaping it repeatedly, which is more painful than the water breath, but it is also more pleasant after completing a cycle of breathing, like a person who has suppressed his thirst for a long time drinking a large glass of sour plum juice.

When Yi Yong is now in the waterfall, he can maintain the breath of fire for 7 hours without making a mistake. However, if it is far away from the water source, this time will be reduced to 3 hours, which is still a significant gap from the "24-hour error-free" norm.

Now it seems that the reason why the Breath of Fire has always been a family heirloom skill of the Purgatory family on Earth is not because the Flame Pillars of the past generations have a view of the portal or cherish themselves.

In fact, only a swordsman who has been honed for many years can have the considerable physique and patience to withstand the pressure of this kind of cultivation, otherwise it is easy to spontaneously combust and die.

And in the ninja world, a place where natural energy is extremely abundant, cultivating Yanhu is also even more dangerous.

Compared with the mental and physical energy that can be stably extracted from the body, it is more than ten times more difficult to use the micro-manipulation ability to control the violent natural energy through the world, so Yi Yong can only use his patience as a water column to adjust and control it little by little......

Just as he was concentrating on indulging in his breath, not far from the river, four shadow clones with bamboo sticks were training the first eight sword types of Flame Breath alone.

As for the last type, Type Nine - Purgatory, which is similar to Mizuhu's Type Eleven Nagi, it can only be used if it reaches the normal middle level and then cooperates with Chakra.

There was a sound of wings flapping, and the red-eyed crow that had left the water to observe the surroundings flew over and landed on the roof of Tanbian's hut.

After it called hoarsely like a timer, the four doppelgangers stopped moving, like four identical statues, standing still and not moving.

A minute passed, and after a noticeable exhalation by Yiyong's main body, one of the clones immediately seized the opportunity and said, "When the time comes, let's practice again, you won't have the strength to go to Naruto." ”

The body of the righteous warrior opened the blue eyes and nodded slightly. Then he formed a handprint, and all the clones immediately dissolved and disappeared, and Yi Yong himself was almost knocked down by the waterfall on the spot, as if someone else had pushed him from behind-

Those four clones had been practicing swordsmanship for a full eight hours from 4 o'clock in the morning to now, and the feeling of soreness and fatigue had descended on the body at a quadruple rate, and I really didn't know what words to use to describe it.

Yi Yong walked out of the waterfall with a gloomy face, and completely sank his body into the water, his swollen muscle tissue continued to contract under the cold but steady stimulation, and the discomfort in his body was slightly relieved, so he had the heart to sort out the experience of the clones in cultivating the sword type.

Five minutes later, his body gradually rose from the water and floated to the surface, his eyes fixed on the front, and a thick white gas overflowing from his mouth and nose.

"The Breath of Fire, the Form of One, the Ignorance of Fire."

A twisted space more than eight meters long swept through the air, accompanied by a water gully of the same length below, fiercely parting to both sides, and Yi Yong's body instantly appeared at the end of this water gully.

It was only then that the surface of the water returned to its original state.

"I don't know the fire, I can use it as an instantaneous technique."

Yi Yong glanced at the air behind him that was distorted by the heat, "But the traces are obvious, and they can only be used to advance head-on." ”

[I don't know what this type should look like when Chang Zhonghou participates in chakra refining......]

Then, repeating his old tricks, he slammed into the door of the hut. Yi Yong took off his wet pants and changed into a set of more life-like clothes that had been prepared a long time ago.

Then he formed a shadow clone again—he was now much more chakra than he had been four months ago, anyway—and began to sit at the small table, studying the homework that Itachi had given him, that is, the principle of the change in the form and nature of the water chakra.

["Only by understanding can you use it better, otherwise it will be difficult to produce something new and completely suitable for you."] ”】

That's what Itachi told him.

Yiyong couldn't refute it, so he agreed, but there was no progress in this part so far, but at least he could understand what those terms meant.

After leaving the mountain stream, Yiyong regained his breath of water that would not be seen by others, picked a path, and returned home.

The house was cold and empty.

In order to fulfill his father's wish of "you must suppress Hinata's family" in the entrance exam, Sasuke is studying seriously in an office of the security team, and he can receive his father's personal guidance every day. Although he misses Yiyong very much, he is also very satisfied to be able to get along with his father in close proximity.

[At least on the fire, I'm much stronger than Yiyong!] 】

He thought so, "The next time I train with Yiyong, I must scare him. 】

Good luck to him.

Itachi, on the other hand, is outside the village, continuing to carry out tasks that will help him enter the shadows, and the details are kept secret.

Mother's words should be with three subordinates who have become a middle ninja to protect a nobleman from the Fire City to the Land of Rain.

Yi Yong looked at the empty living room and kitchen, remembered the mansion he was given to him when he was a water jet, and remembered those nights when he tossed and turned on the futon, and a familiar sense of loneliness surrounded him.

The next moment, Yoshito remembered the seemingly meaningless "I'm back" when Naruto went home and opened the door.

He also understood what that really meant.

"Don't let him wait."

Yi Yong said to himself, dispelling the faint emotion, all the way to the storage room at home, and dragged out the induction cooker and rice cooker that had been eliminated for many years.

This was the last time he came back from Naruto's house, his mother offered to let him bring it over, only to tell him not to disturb Naruto for too long.

Yiyong cleaned the two electrical appliances, then went back to his room to find the recipe that had been re-copied before—because the original characters were too ugly to pass on to others—and then set off from home.

……

When Yoshito walked to Naruto's door, he was sure he heard a groan of pain.

[Have you diarrhea again? 】

Yoshito frowned, [Didn't the Hokage say that he would let the merchant sell him something? 】

"Knock knock."

He could hear Naruto walking, it wasn't supposed to be in the toilet, so he put his things down and knocked heavily on the door.

"Is it Righteousness?"

Naruto Uzumaki's voice was joyful, but a little tight, in line with Yoshiyu's guess that he was unwell.

"Open the door."

Yiyong said in a flat tone, "It's me." ”

"Can you wait a minute? I want to go to the toilet. ”

His tone became more nervous, followed by the sound of the toilet door slamming shut.

Yiyong was worried that his physical condition was serious and his mouth was stiff, so he grabbed the doorknob and unscrewed it with a click.

[If not, take him to the hospital first.] 】

After the door was forcibly opened, the familiar room came into view, but the mop that had fallen to the ground and the wet floor were new, indicating that Naruto was cleaning before he arrived.

Then, an unbearable smell pierced Yiyong's nostrils. If it was Tanjiro, he would probably have said that he was choked until his throat hurt.

[But this smell seems to feel familiar......]

The faucet in the toilet rang.

The sound of running water that was light and heavy and stopped meant that Naruto was not sitting on the toilet, but was hurriedly rinsing something, and making an inaudible inhalation sound that was obviously intended to avoid being heard by Yoshiyu.

Instead of forcibly breaking open the toilet, Yiyong silently walked to the refrigerator and opened the door, taking out a carton of milk.

"The production date is December 1, and the shelf life is 45 days."

Yi Yong's eyes became slightly sharp, "There are still 5 days to expire." ”

[So, is it from expired milk to expired milk?] 】

There were sixteen cartons of milk in a carton, and there were exactly sixteen cartons in the refrigerator, which meant that these were the milk that Naruto had just bought today or yesterday.

The scene of the three generations of Hokage's promise to Naruto flashed in his mind, and the corners of his mouth twitched down slightly.

In the Ghost Slayer Team, he hates people who are irresponsible, but who speak nicely.

If the Hokage feels that he is too old to manage so many things, and retreats to the second line like Master Scale, why should he do this, and he can't do what he promised, and he will disappoint people in vain. Perfunctory is more annoying than doing nothing.

Yiyong closed the refrigerator door, but the bathroom door opened.

He cast his gaze and found that Naruto Uzumaki's first look at him was not surprise, but rather a subconscious retreat like Itachi had been found in the kitchen. Then Naruto asked in surprise, "Yoshiyu, how did you get in?" ”

This is what Sasuke said when he turned his head when he stayed up all night reading the villain book, but saw his mother standing quietly behind him, full of the taste of emptiness, as if there was something that could not be known.

Then, Naruto glanced at the door where the heat was constantly gushing out, and let out a nervous exclamation.

"I'll change the lock for you."

Yoshiyu's gaze lingered on Naruto's face for a moment, then at his right hand clinging to his thigh, "Still, do you have to wear gloves at home?" ”

It was a green children's woolen glove, and if it was outside, it didn't seem to be anything out of the ordinary. But at home......

"Because I feel a little cold."

Naruto scratched his head and laughed twice, pointed to the gate and said, "It turns out to be colder now......"

"You're lying."

Yi Yong interrupted, standing in place like an ice sculpture, his eyes like frost.

He had already carefully looked at Naruto's hands with a clear view, and was suppressing his faint unhappiness, but he didn't say it directly.

Naruto had never seen such a stern expression that was not malicious, and he didn't know how to deal with it, so he could only look down at his slippers. It was as if he had done something wrong.

"Sit down first."

Seeing him like this, Yiyong finally breathed a sigh of relief. He was a little embarrassed to preach to a child who was eight years younger than the first time he met Tanjiro.

He dragged a chair to block the leaky door, and then sat down at the small coffee table next to the bed as a puppet-like Naruto, who sat across from him.

"Put your hands on the table."

Naruto obediently complied.

Today's volunteers are a little scary.

Although Yoshiyu's expression was not very different from the last time, not only Naruto felt a low air pressure, but even the fox hidden in his stomach also sensed abnormality, so he squinted behind the iron gate as if watching the play.

Yoshito grabbed Naruto's right wrist, and the latter unconsciously jerked back, as if afraid of what would happen next.

When he raised his head, his deep blue eyes and his big azure watery eyes looked at each other.

After a moment, Naruto understood what Yoshito meant, pursed his lips, tilted his head to the side, and closed his eyes tightly.

But the next moment, his arms tensed like cramps, and he resisted the desire to retreat, but a prayerful hiss came out of his throat, matched with his reddened and twisted face, as if he was suffering from the sharp pain of a soldering iron.

He had every reason to show that look.

Even though the action of Yoshito uncovering the gloves was light enough and very slow, there was a rough sound like tearing Velcro, tearing off a layer of skin from Naruto's hand.

Yiyong's mouth opened slightly.

What he saw with the naked eye made him more sad than what he saw with transparency.

The epidermis of Naruto's entire right hand was festering as if it had been corroded by something, and only a small amount of corn-colored glue-like adhesion remained on the bleeding dermis. To put it mildly, this is a chicken feet that have been boiled to the point of peeling.

Since Naruto had forcibly put on woolen gloves to cover his injuries, there were still a lot of fine woolen slags stuck to the wounds under his eyes. The ones that stood up were okay, and the ones that lay down almost had to melt into the skin, and once they were about to be taken out, the pain was not sure how Naruto would be able to bear it.

How strong his will must have been to put such a rough glove on his hands.

Unconsciously, he felt almost exactly the same way he felt about Naruto when he fought seven days ago.

Yiyong's nose dilated slightly, and the words he wanted to say were hidden between his teeth that were crowded together.

[The other hand, even if you don't have to look at it, you know that it's almost the same.] 】

"Do you have a medical kit at home?"

"In ...... Behind the mirror in the toilet. ”

Naruto shivered in pain, tears rolling in his eyes, but they never came out.

[It was given to me by my grandfather because I always fell.] 】

"Don't move here."

After settling in, he entered the bathroom and found that the pungent smell from before was even stronger.

He saw Naruto's bucket washing the mop in the shower, and that's where the smell came from. There was a bottle of detergent identical to his home next to the bucket, which explained the faintly familiar smell.

But Yi Yong, who is in charge of the housework, knows very well that this detergent itself is by no means the pungent smell it is now, otherwise how would anyone buy it.

He held his breath, unscrewed the bottle of detergent with bad guessing, and looked inside, and sure enough, the color of the liquid was different from what he was using at home.

[Someone added something to it.] 】

Yi Yong made a judgment.

[Is it intentional?] Or was it an accident? 】

He screwed the detergent bottle cap on and set it aside, and without saying a word, took out the blue packet behind the mirror, took out a small pair of tweezers from it, and returned it to Naruto.

[I'll talk about that thing later, it's important to heal the wounds.] 】

He saw Naruto's eyes reddened, his teeth clenched, and the inside of his shirt elbow still had the same water stain he had left there, but Yoshito didn't let his eyes linger there.

He pressed Naruto's wrist and gently probed the tweezers, but stopped when he was about to make contact,

"I'll knock you out."

"Otherwise, it will hurt even more than it already is," he earnestly proposed. ”

Naruto was stunned, as if he had briefly withdrawn from the burning pain, pondering Yoshiyu's words.

But immediately, he gave another hearth smile.

"No need......

There was a sincere light in his eyes.

"Because when I was grabbed by Yiyong's hand, it didn't hurt as much as just now."
