Back home,

Rin Uchiha hurriedly threw away the shoes on his feet and walked barefoot into the room. The room was messy and looked like it had never been cleaned up, and it was hard to imagine that it was a girl's room.

Rin Uchiha walked his feet over the messy bottles in the room, walked to the corner of the room, and took out the two bottles of wine that Ishida Shunya had just given him from his pocket, his eyes blazing and impatient.

"Is it to drink you first? Or are you? ”

The wine that Fool Jun also made is indeed cheaper than those on the market, and I heard that the "Ganges Water Moutai" he buried before is about to be unearthed, so he must steal it out and drink it when the time comes.

"Ahem!"

At the door, the Uchiha who was still a child coughed, and the Uchiha Rin, who was still lying on the ground, quickly got up and covered the two bottles of wine in his hand, looked out alertly, and after seeing that it was the water, he said with a wary look:

"Zhishui, you're back, I didn't drink today!"

"Sister, drinking alcohol is not good for your health." The Uchiha said with a smile, just about to take a step into the house, but had to stop.

There's really no place to stay.

The room was littered with wine bottles, ninja equipment, underwear... This is the room he cleaned up two days ago, why is it messy again!

Uchiha covered his forehead and complained, "Sister, how old are you, why is the room still so messy!" ”

Uchiha Rin waved his hand and said indifferently: "It's okay, I can find everything anyway, and besides, you really don't want to clean up my room, every time you clean up, I can't find my things again!" ”

While talking, she secretly hid two bottles of wine behind her and made them cross-legged on the bed to prevent her brother from seeing them. Because the middle ninja exam was approaching recently, Zhishui gave her a death order not to let her drink, and confiscated the wine while she was away.

Originally, the fact that there was no alcohol to drink made Uchiha Rin more or less distressed, and he wanted to teach Shisui a good lesson, but he just raised his hand and saw Shisui's cute face, and he didn't dare to fight for a while. She only has this younger brother left, and it's okay to flirt with her, but she really can't do it when she learns a lesson.

Uchiha Shisui finally found a way in the messy ground, sat down on the bed, and said in a deep voice: "Sister, you have been to Brother Ishida's house a little often recently, and they are... What are you going to do there? ”

"Cultivation, what else can you do?" Rin Uchiha glanced at his younger brother, "Shisui, why are you suddenly asking this?" Done your homework at Ninja School? ”

"When you're done, just ask."

The Uchiha shook his hand repeatedly, then scratched his head again, thinking about the speculation he had recently thought of, and didn't know how to speak for a while.

How do you say that?

I can't ask my sister directly, if Ishida Shunya is with him at home....

Ahem!

Although I don't like Ishida Jun very much for snatching his sister, this is a major life event after all, and it can't be described as liking it or not.

Uchiha wiped the sweat from his forehead and coughed lightly, "... I remember, sister, you've had a good relationship with Brother Ishida since the ninja school. ”

"That's right." Rin Uchiha laughed, "That stupid guy made me a bento every day, but he was very lazy and often forgot to bring me a bento. But the food he cooks is just a good job. ”

Still alive?

Sister, do you still go to eat every day? Not only rubbing the bento every day, but also rubbing it to his house?

What are you not honest and honest?

Uchiha's thoughts became clearer and clearer, and he stopped talking: "Then you and Brother Ishida... Isn't it..."

Uchiha frowned and said, "Shisui, what's wrong with you today?" Talking so badly? ”

"I... I'm this..."

Uchiha Shisui frantically thought about the wording in his mind, and with his sister's unfrank character, he asked her directly if she definitely couldn't get the right answer, and she had to find a way to knock on the side. In this way, my sister dared to tell the truth.

And in the last few days, my sister has come back late every day, and every time she comes back, she complains that she is tired, and then hides in her room alone and giggles... At first, it didn't feel like much, but since the girls in the class shared with him some secrets that only happen between men and women, Uchiha's eyes were instantly opened.

He finally knew what his sister had been smirking at lately.

Uchiha Zhishui felt a breath in his throat, but he just couldn't ask, so he had to turn his heart sideways and knock on the side:

"Sister, aren't you, you're about to break through something..."

"It's really broken!"

Seeing Uchiha Shisui's surprised expression, Uchiha Rin gave him a blank look, feeling that his younger brother was making a fuss, "My recent ninjutsu practice has been going well, so naturally I have broken through!" But you don't have to worry about me in the last few days, that guy from Cloud Ninja Village, I'll teach him a good lesson! ”

"Oh! It turned out to be ninjutsu, so it's okay, it's okay. Zhishui breathed a sigh of relief instantly, and the heart that was hanging just now finally fell.

"You're fine, but I feel like you're weird today." Rin Uchiha asked.

"Strange? What's wrong with me? Sister, are you mistaken? ”

"You just talked so much, it's strange to look at." Rin Uchiha narrowed his eyes and asked, "Could it be..."

"Could it be?"

"Do you have a girlfriend?"

The Uchiha sneered instantly, almost throwing up the dinner he had just eaten. I was worried just now that you and Ishida Junya had a misfire, why did you turn around and you were still worried about my emotional problems.

But then again,

I can hear my sister making such a joke, so it should probably be fine....

Probably.

Then the Uchiha stopped coughing lightly: "Then I'll go back to the room first, by the way, the elder and the patriarch asked me to call you to Nanga Shrine." ”

"Got it, I'll go now."

Rin Uchiha smiled and took the opportunity to put the bottle in his sleeve without the slightest flaw.

Seeing Uchiha Shisui cover her face and leave, she felt strange: "I always feel that Shisui is strange today, could it be that the boy's puberty has arrived?" No, I'll have to talk to that idiot about this later. ”

Rin Uchiha took his brother's life's events to heart, and then came out of the house and went to Nanga Shrine while drinking.

....

Ishida Shunya's house, in the basement,

In front of Ishida Shunya stood a shadow clone of himself, wearing high-strength insulating rubber all over his body, and at the same time attached to the Thunder Chakra all over his body, as if he was simulating Ai Kai Thunder Armor.

And Ishida Jun also began to seal,

Rachel!

The sound of a thousand birds chirping in unison sounded again in the basement, this A-grade ninjutsu that had just been mastered in the hands of Uchiha Rin,

Today finally under the improvement of Ishida Shunya,

Became an S-class ninjutsu!

Rachel done!

Rachel is Chidori's upgraded ninjutsu,

Chidori's biggest trick is the speed of the sprint, combined with the power of Chidori itself, so as to achieve a strong penetration effect.

And if the long-range spike is missing, the power of the thousand birds will also be greatly reduced, and Rachel is based on this shortcoming.

Increased power, allowing ninjutsu to get the same piercing and cutting power without having to thrust at long distances.

The relationship between the two is somewhat like that of the Spiral Pill and the Great Jade Spiral Pill, with the same root and the same origin, but there are indeed differences.

In Sasuke's early days, as well as Kakashi's early use of Chidori, he couldn't deal massive physical damage without relying on long-range thrusts. In the late game, Sasuke's short-range thrust can only deal chakra-like damage to the target, but Kakashi's short-range Rachel can deal physical damage while dealing chakra damage, and the difference can be seen.

When Kakashi introduced Chidori, he explained that this ninjutsu was specially developed for assassination, but in fact it was rarely used as an assassination in the original work. And whether it is Kakashi or Sasuke, when using Chidori in the early days, he must use long-range stabs, which are easy to expose weaknesses and cannot play the role of assassination at all.

However, there is also a huge flaw in the ninjutsu of Chidori, which needs to rush quickly to the opponent to play its role, and will not be able to see the enemy's movements clearly because the speed is too fast, and it is easy to expose weaknesses so that the opponent will fight back, and it is a ninjutsu that must be matched with the insight ability of the writing wheel eye to make up for the shortcomings and play the greatest role.

Although with his combat experience, he can indeed predict the enemy's movements, but if he encounters a ninja or above and rashly uses Chidori without writing a chakra, it is still easy to be counter-killed. Therefore, Ishida Shunya himself did not use Chidori as his usual ninjutsu, but only as a ninjutsu for practicing Lei Dun Chakra.

Of course, Ishida Jun can also develop the ninjutsu developed by Kakashi in the later period - Purple Electric on the basis of Rachel, then he may incorporate this ninjutsu into his usual ninjutsu.

Present

Ishida Shunya uses Rachel to stab at the shadow clone in front of him wearing the "Simulated Thunder Armor".

The thunder and lightning in his hand slashed at Shadow Splitter like a quick knife, and the "Simulated Thunder Armor" on the surface showed a slight crack, but it was not broken.

The first round of the experiment ends.

It's nonsense that this "simulated thunder armor" wants to imitate Ai's thunder armor 100%, after all, it is someone else's secret technique, and he really can't copy it with the naked eye.

However, Ishida Junya's test this time is just to verify an idea in his heart.

The second round of experiments,

This time, the offensive and defensive relationship between the two sides was switched back and forth, and this time the shadow clone of the "Simulated Thunder Armor" was responsible for the main attack. Strengthened by the Thunder Armor, the shadow clone rushed at lightning speed.

But Ishida Shunya instantly saw through the shadow clone's movements, his body opened slightly sideways, and just passed by the attacking fist, as if he was very stingy with his own pace, he flashed the attack, but he also came to the shadow clone.

The shadow clone couldn't react, and Ishida Shunya seized the opportunity and stabbed him with Rachel.

This time

Rachel and the Thunder Armor came into contact with each other, and after a brief collision between the thunder and lightning, Rachel actually stabbed into the Thunder Armor effortlessly, hitting the body of the shadow clone.

Bang!

The shadow clone was hit by Rachel and disappeared into smoke.

Feeling the experience passed on by the shadow clone, Ishida Shunya paused, he had a little realization in his head about the experiment just now, and hurriedly recorded the new ideas that popped up in his head.

subsequently

A similar experiment began.

Sure enough,

The results of the experiments were all the same.

"It seems that the weakness of this ninjutsu... No, it's Ai's weakness that I found! ”
