In Konoha: Eating Goro Goro no Mi at start.

Senju Nawaki has been lying in ambush here for a long time.

In Nawaki's impression, since he could remember, his sister has never paid attention to him.

 He is almost ten years old this year. He will graduate from the Ninja School soon, but his own sister still sees him as a stranger.

Nawaki still remembers that his grandmother said that as long as he practices well, his sister will pay attention to him.

But he has been the first in the Ninja School for four consecutive years, and his sister has never taken the initiative to visit him once.

Even if he takes the initiative to find his sister, he will be driven away quickly.

Really, is this Uchiha Rei good at fighting?

How many first places has he won? !

After ambushing for nearly three hours, Nawaki finally found his target.

So, Nawaki threw out the shuriken he had prepared in advance.

Shuriken is made of wood, and it won't kill you.

It just hurts.

But no matter how painful it is, how can it compare to the pain of being ignored by your own sister years?

Feel the pain! Evil Uchiha!

No way? So weak?

Nawaki looked at Rei's figure and stopped there, with a little surprise in his eyes.

Can't you avoid this level of shuriken throw?

How did such a fool get his sister?

Is it just relying on that face?

At this moment, the joy of the successful ambush did not come as expected, and Senju Nawaki became even more angry!

Whether as my sister's husband or as my Senju Nawaki's brother-in-law.

With such strength, are you qualified?

Senju Nawaki closed his eyes and looked again, but found that Rei, who was standing there, had disappeared.

  Disappeared?

"Who are you looking for?"

A warm voice sounded, and Senju Nawaki answered almost subconsciously.

"Uchiha Rei."

Who is it? !

Senju Nawaki turned his head sharply, and at that moment.

Looking at Rei who suddenly appeared in front of him, Nawaki almost subconsciously stepped back.

But heis on the tree...

"Ah!!!"

When the feeling of weightlessness appeared in his heart, Nawaki shouted.

With a flash, Rei's figure appeared on the ground, and one hand grabbed Nawaki's collar.

"Swish~"

The sound of fabric being torn was heard, Nawaki's windbreaker was directly torn, and he fell heavily to the ground.

  "Bang!"

Along with the dust rising up, there was also the sound of the body colliding with the ground.

 "Hiss~"   

Looking at Nawaki who fell to the ground and gasped for cold air, Rei pursed his lips and swallowed his saliva.   

The quality of the clothes of Senju's family is not very good...   

But it also hinders some of the power to a certain extent... right?

Lying on the ground, Nawaki slowly breathed a sigh of relief.   

At least, my brother-in-law is not a waste.   

"Is your neck okay?"   

Looking at Nawaki who was lying on the ground and couldn't get up, Rei felt a little helpless for the first time.  

"As expected of... Uchiha... so strong!"  

Senju Nawaki supported his neck with one hand and his waist with the other, twisted on the ground for a long time, and finally stood up with the help of Rei.   

"So you came here just to test my strength?"   

After helping Nawaki up, Rei looked at Senju Nawaki in front of him and blinked in disbelief.   

"Yes, I always have to know how strong the man who will be with my sister in the future is, right?"   

Nawaki rolled his eyes disdainfully and looked at Rei as if he was an idiot.   

"Huh? Haven't you heard of the name of Konoha's Lightning Sword?"   

Rei pursed his lips after hearing this, and asked Senju Nawaki in surprise.

"The Lightning Sword of Konoha? Who is he? Is he famous?"

Senju Nawaki was stunned after hearing this, and asked Rei in surprise.

Although Nawaki has been studying in the Ninja School for four years this year,

in fact, except for the exam, Nawaki has never been to the Ninja School.

Instead, he has been studying with Uzumaki Mito.

"Nothing."

Seeing Nawaki's clear and stupid eyes, Rei pursed his lips and shook his head.

"What was the technique that you used to suddenly disappear just now?"

Looking at Uchiha Rei in front of him, Senju Nawaki hesitated for a moment and asked Uchiha Rei.

"I won't tell you. "

Rei shook his head at Nawaki after hearing this.

"Huh?"

Nawaki was stunned after hearing this. Nawaki thought that Rei would reject him, but he didn't expect that Rei would reject him so straightforwardly.

"I won't tell you."

Rei continued to shake his head after hearing this in Nawaki's surprised eyes.

"Teach me~"

If Rei refused more tactfully, Nawaki might have let it go, but Rei refused so bluntly that Nawaki became interested.

So Nawaki took out the method he used to deal with Uzumaki Mito.

"Senju Nawaki!"

At this moment, a loud shout sounded, and Rei was very keen to notice that Nawaki's body suddenly stiffened.

"I'll come to see you tomorrow!"

Before the voice fell, Nawaki had already run away.

Looking at Nawaki's back as he left, Rei chuckled and shook his head.

"What did he do?"

Tsunade came to Rei's side .

"Nothing, he said he wanted to see if I have the strength to protect you."

Rei chuckled and squeezed Tsunade's hand.

"Huh? Wait for me to twist his head off."

Tsunade raised her eyebrows and took a step to chase Nawaki.

Seeing this, Rei gently pulled Tsunade into her arms.

"It's okay. It's normal for Nawaki to be worried."

Rei chuckled and walked towards the house with Tsunade in his arms.

"He's just too well protected by his grandma and doesn't know anything."

Tsunade's hands covered Rei's hands.

"I didn't expect Tsunade's deterrence to be so strong."

Rei put his chin on Tsunade's neck and whispered in Tsunade's ear.

"Huh!"

Tsunade raised her chin slightly and snorted.

At this time, the two had already come to the bed.

Both cuddled together and Rei took initiative to kiss Tsunade.

  ...

"Brother-in-law, are you hungry?"

Early in the morning, Rei, who was training with Tsunade at the third training ground, saw Senju Nawaki coming with a lunch box.

Orochimaru and Jiraiya also subconsciously looked at Senju Nawaki.

"Thank you, I had breakfast this morning."

Rei shook his head and declined Nawaki's kindness.

Rei was not opposed to teaching Nawaki.

However, when facing such a child, you can't just go along with him. You have to let him beg you. Only after he pays the price will he not just keep the enthusiasm for three minutes.

"Are you thirsty?"

Nawaki immediately took back the lunch box and took out a bottle of water from his arms.

After asking Mito about Rei's information last night, Nawaki realized how powerful his brother-in-law was.

One sword can force the Four-Tails Son Goku to show up.

And Rei that year was two years older than he is now.

And it was at that moment that Nawaki understood what the title of Lightning Sword in Rei's mouth meant.   

Lightning, because he is so skilled in lightning style that he can transform himself into an element.

  I, Senju Nawaki, also want to be so powerful!

"Not thirsty."

Rei shook his head after hearing this, paused, and asked Nawaki.

"Shouldn't you be in the ninja school at this time?"

As Rei's voice fell, Senju Nawaki's face suddenly fell, and Tsunade's eyes became dangerous at this moment.

"I learned everything with my shadow clones. Wasn't it the same for you and your sister back then? I usually practice with my grandma."

Senju Nawaki's eyes immediately moved away from Rei, and explained to Tsunade in a panic.

Senju Nawaki was still clear about Tsunade's temper.

Sure enough, he is worthy of being the Lightning Sword of Konoha, and he can even suppress a guy like Tsunade!

After hearing Nawaki's explanation, Tsunade's eyes slowly calmed down.

"Then why don't you continue to practice with your grandma now?"

Tsunade asked Senju Nawaki.

"I want to learn Kenjutsu from my brother-in-law! I want to be a swordsman too!"

Senju Nawaki said loudly to Tsunade.

After that, Senju Nawaki closed his eyes and quietly waited for Tsunade to lose her temper.

Tsunade chuckled at this, but did not lose her temper. Instead, she looked at Rei.

Tsunade knew Rei's strength. He was more than enough to teach Nawaki.

Although she had never taken care of Senju Nawaki since he was a child, he was still her own brother after all.

If possible, Tsunade still hoped that Rei could teach Senju Nawaki.

Of course, it depends on Rei's intention.

"Are you so afraid of your sister?"

Rei nodded slightly in Tsunade's eyes, came behind Nawaki, and put his hands on Nawaki's shoulders.

"It's not that I'm afraid... I just have a little respect."

Nawaki was slapped by Rei, and he trembled all over. After reacting, he said to Rei a little embarrassedly.

"Do you want to learn Kenjutsu from me?"

Rei chuckled and asked Nawaki without getting entangled in this issue.

"If other skills are possible, I would also like to learn them."

Nawaki smiled and said to Rei.

"Oh, you haven't learned Kenjutsu yet, and you want to learn other things?"

Rei raised his eyebrows and asked Nawaki indifferently.

"Then I will learn Kenjutsu first!"

"But I think it's difficult for you to learn it. After all, your performance last night was really...too bad."

Rei shook his head in distress and said to Qian Shou Nawaki.

"I will work hard! Give me a chance, okay?"

 Nawaki said to Rei.

"Okay, do you see that over there? There is a shadow clone of mine over there. Go find him and let him teach you the initial practice first."

Rei nodded and pointed in a direction and said to Nawaki.

Over there is the shadow clone that Rei used to learn the Flying Lightning God Technique.

"Okay!"

Nawaki nodded and trotted away.

"Thank you."

Tsunade came to Rei, held Rei's hand, and said to Rei.

"You're too polite."

Rei smiled and shook her head. If possible, Rei also hopes to bring Nawaki with her.

In this way, she can still take care of Nawaki, so that Nawaki will not be sacrificed in the mission like in the original book.

If possible, Rei still doesn't want Tsunade to be sad.
