Return to Konoha and Yu's home.

The door opened silently, and a ninja with a white mask on his face slowly walked into the room.

Judging from the long purple hair behind the mask like a waterfall, and the slender figure that the black uniform uniform dress that the dawn can't hide, I know that this is definitely a beautiful woman in the city.

"Alas...... I don't know where that nasty guy has gone......"

Some complaining voices sounded, and after slowly taking off the white mask, a cold and gorgeous face was exposed, but there was a trace of complaint on this beautiful face at the moment, it was Mao Yue Xiyan who had just returned from a mission outside.

Since the beginning of Shippuden, there have been different things happening almost every day, so Yu's itinerary has become relatively busy, although Xiyan didn't say it, but it is inevitable that he will miss his sweetheart in his heart.

"Sunset ......"

At this moment, a familiar voice suddenly sounded in the room, and Xiyan's eyes suddenly widened, almost thinking that he was too worried about it because he had auditory hallucinations.

"Feather?!"

Turning around in surprise, Xi Yan really saw that Yu, who hadn't been seen for a while, had appeared behind her at some point, and couldn't help but say that a pair of solid arms hugged her into her arms.

"I'm sorry, I've been going on a lot lately, ignoring you and the red ......"

Seeing the cold and gorgeous beauty in her arms so worried about herself, Yu couldn't help but feel a little guilty even if she was hard-hearted.

Between the whispers, he hugged Xiyan's thin waist and hugged her into his arms, and the two of them kissed tightly together, and suddenly the whole room was filled with a charming atmosphere.

"Hmm...... What are you going to do?"

After a long time, the lips of the two kisses finally parted, and Xiyan was still immersed in the charm just now, but he found that his waist and knees were weak, and the whole person had been hugged by Yu and walked towards the room inside.

"It's rare that no one bothered us today...... Red also happens to be here, what do you think I'm going to do?"

Looking at the glamorous fat sheep that fell into the wolf's claws in his arms and was still ignorant, Yu felt a great interest.

"You're going to die!"

Hearing Yu's ridiculous words and seeing the ill-intentioned smile on his face, Xiyan didn't understand what he wanted to do, and suddenly smacked lightly, but the pretty face with a crimson face was buried deep in Yu's chest like a bell......

……

A driving range on the outskirts of Konoha.

"Alright, let's start cultivating!!"

On a verdant meadow, not far from it is a man-made waterfall that was reclaimed by the use of earth and water ninjutsu.

After this trip to the Land of Water, he saw the earth-shattering power of the feather, and then thought of the experience of being easily defeated by Sasuke in the country of Tanoka and left, after returning to Konoha, Naruto pestered Kakashi, who had used the kaleidoscope writing wheel eye to recuperate in the ninja hospital to recuperate, and shouted to develop a new ninjutsu.

"Hey, hey, hey......"

Looking at Kakashi, who had just come out of the ninja hospital in front of him, Naruto let out an inexplicable smirk.

"What's wrong?!"

Seeing Naruto's sudden smirk, Kakashi looked confused.

"No, it's nothing......"

"It's just that I haven't practiced with Kakashi-sensei for a long time, and I'm a little inexplicably excited......"

Feeling the blank gaze of Tsukakashi, Naruto still smirked and reached out and touched the back of his head.

“……”

Seeing Naruto's performance, Kakashi was speechless for a while, but there was an inexplicable warm current in his heart, thinking that maybe this was Naruto's power to infect others invisibly.

"Well, time waits for no ......"

"The enemy we will face next will only get stronger and stronger......"

Looking at Naruto in front of him, Kakashi spoke, "And the main purpose of this cultivation is to successfully inject chakra nature changes into your Spiral Pill and complete the ninjutsu beyond Spiral Pill......"

"Ninjutsu ...... beyond Spiral Pill"

"Is it like the spiral pill used by Yu before?!"

After hearing Kakashi's words, the first thing that came to Naruto's mind was the image of the previous Yu casting the Immortal Law Arashi Escape Hard Vortex Water Blade to destroy the world, and he immediately screamed excitedly.

Thinking of this, Naruto suddenly became more and more excited, and he almost couldn't sit still at the thought of being able to learn ninjutsu, which was so powerful and magnificent.

Seeing Naruto's excited face, Kakashi fell silent for a while, and his mind also recalled the terrifying power of the Yu's Senfa Arashi Escape Hard Vortex Water Blade, and he couldn't help but feel a little afraid, if it wasn't for his Kaleidoscope Sharingan's Hitomi Divine Might just in time to catch up, maybe all of them would be dead by now.

"No, it's not a ninjutsu ...... of Yu's level"

But seeing Naruto's excited appearance, Kakashi couldn't bear to hit him, "The spiral pill he used contains at least two or more chakra nature changes, and it also adds the chakra of the immortal mode, and the power can't be estimated normally at all......"

"Chakra nature change?!"

Naruto's mouth was glazed open, and it was clear that Kakashi's words sounded as deep and incomprehensible to him as a complicated heavenly book.

"Under normal circumstances, any two innate chakra nature changes are combined to form a new nature change, which we call the Blood Inheritance Limit ......"

Seeing Naruto's still confused expression, Kakashi explained to him in detail with some helplessness: "For example, Yamato's Wood Escape is a combination of the nature changes of earth and water, and Ha's Arashi Escape is a combination of the changes in the properties of water and thunder......"

"And the combination of the three chakra nature changes into a new nature change is the level that surpasses the blood inheritance limit, which we call the blood inheritance elimination ......"

While explaining to Naruto, Kakashi's own face became more and more solemn, "That ninjutsu of Scarlet Feather...... Although it is not the Blood Succession Elimination, he has added the Immortal Mode Chakra to his Lan Dun, so the power will definitely not be under the Blood Succession Elimination, and even above that......"

"Blood Succession Elimination?!"

Naruto's eyes widened in surprise, although he still didn't understand the full meaning of what Kakashi said, but at least he understood one meaning - that is, it was impossible for him to learn ninjutsu of the level of Yu for the time being, so he hurriedly said, "I don't know what it is...... But Kakashi-sensei, hurry up and teach me what chakra nature change is!I must surpass that guy and chase Sasuke back!!"

Beyond the Crimson Feather......

This kid really dares to say it......

Looking at Naruto's confident and optimistic face in front of him, Kakashi shook his head a little helplessly in his heart, and said with a wry smile on his face, "It's still too early for you to say this...... You'd better start honestly from the basics and learn how to inject your own chakra nature change into the Spiral Pill first!!"

After a while, Yamato also came to the practice ground, brought Naruto chakra test paper, and after judging that his chakra nature changed to wind, Kakashi then began to teach Naruto how to use shadow clones to cultivate together, creating a prototype for the Wind Escape Spiral Pill shuriken.
