Naruto: The man is in the Senju, but the Sharingan

"Izuna, let's have a competition to see who can reach the top of the mountain first!" As soon as Senju Kagamikawa finished speaking, he took advantage of Uchiha Izuna's lack of reaction and used chakra to climb up the mountain.

Uchiha Izuna was stunned for just a second before reacting. Seeing that Senju Kagamikawa had already run a distance away, he covered his feet with chakra and chased after Senju Kagamikawa, cursing with a smile:

"Well, you, Senju Jingchuan, actually cheated and got ahead?"

Senju Kagamikawa was ahead for a while. Hearing Uchiha Izuna's accusation, he did not turn around, but just shouted:

"I'm not cheating, I'm clearly outsmarting you, it's obviously Izuna you didn't react!"

……

Senju Kagamikawa relied on his breathing skills to cheat and easily reached the top of the mountain. Not only was his breathing not disordered at all, but he didn't even sweat a drop. He even had a smile on his face and a relaxed expression as he cheered on Uchiha Izuna, who hadn't climbed up yet.

Although Uchiha Izuna was not as fast as Senju Kagamikawa, he was only a dozen seconds late.

Finally, Uchiha Izuna directly increased the output of chakra and jumped to the top of the mountain.

Uchiha Izuna, who had done such intense mountain climbing early in the morning, only had a slight flush on his cheeks and a thin layer of sweat on the tip of his nose, but his breathing was not disordered at all.

Uchiha Izuna looked a little annoyed, he didn't expect that he would lose to Senju Kagamikawa. Although he always knew that the Senju family's human body skills were top-notch and their physical fitness was terrifying, Uchiha Izuna didn't expect that Senju Kagamikawa, who was so much younger than him, would also possess such terrifying physical fitness.

"Wow! I didn't expect that you, Izuna, have such good physical fitness." Senju Kagamikawa looked at Uchiha Izuna with a smile and praised him.

If someone else said this to Uchiha Izuna after defeating him, Uchiha Izuna would definitely think that person was mocking him.

But the person who said this was Senju Kagamikawa, and Uchiha Izuna understood that Senju Kagamikawa was simply praising him.

So, the arrogant Uchiha Izuna folded her arms across her chest, tilted her head slightly, pouted her lips, and said:

"No way, I'm not as good as you, Jingchuan."

"I didn't expect that your taijutsu skills are so amazing, Kagamikawa. Your speed is so fast that I can't catch up with you. And judging from your current state, you obviously still have some strength left."

Uchiha Izuna turned his head again and looked at Senju Kagawa, thinking of the abilities that Senju Kagawa had displayed in front of him before, and also noticed Senju Kagawa's long and steady breathing at this time.

Uchiha Izuna was reminded of the fighting moves that Senju Kagamikawa had used before.

A flash of inspiration suddenly appeared in Uchiha Izuna's mind:

"Breathing? Jingchuan, your breathing never seems to be disordered, whether in battle or just now..."

No matter how steady normal people are in battle, their breathing will change when facing a life-and-death moment, but Senju Jingchuan is different.

Although Uchiha Izuna had never fought with Senju Kagawa personally, Senju Kagawa had never actually appeared on the front line of the battlefield, so Uchiha Izuna rarely saw Senju Kagawa fight.

The only time was...

Uchiha Izuna thought of the powerful move that Senju Kagamigawa used when they were besieged by the Feathered Clan, which shone with the glittering sunlight...

"So, it turns out that the key point of your moves, Kagamikawa, is 'breathing'..." Uchiha Izuna sighed:

"I didn't expect that human breath could contain such powerful energy."

Senju Jingchuan smiled slyly: "Yes, I never thought that breathing could have such a powerful force... However, these are the experiences of our ancestors, and I am only lucky enough to understand a little bit..."

Hearing what Senju Kagamikawa said, Uchiha Izuna nodded in understanding.

Uchiha Izuna understood that every ninja had his own unique skills and secrets, and he would not be so reckless as to directly ask Senju Kagawa about the secret of the "breathing method", even though Uchiha Izuna had already regarded Senju Kagawa as his best friend, but who said that best friends could not have their own secrets?

Not to mention Senju Kagamigawa, Uchiha Izuna also has a secret in his heart.

This secret is also the reason why Uchiha Izuna has been unable to sleep at night recently.

Due to some accidental reasons, Uchiha Izuna accidentally touched a secret switch when she went to the Uchiha Shrine to worship.

The switch was turned, and a secret underground door appeared in front of Uchiha Izuna.

At that moment, a voice suddenly emerged in Uchiha Izuna's heart, and that voice said, "If you don't go in and take a look, you will regret it for the rest of your life."

Driven by this strong desire, Uchiha Izuna finally went in.

After entering, Uchiha Izuna discovered that this underground place, which he thought contained important secrets, was actually very empty. There was only a bare stone tablet in the huge space.

Uchiha Izuna approached the stone tablet. From what he could see with the naked eye, there was nothing important recorded on the stone tablet. The only focus was on the content related to the Sharingan - only when subjected to strong emotional stimulation would members of the Uchiha clan with blood open their eyes.

This was the information that Uchiha Izuna already knew, but since this stone tablet appeared in an important shrine of the Uchiha clan and was placed so secretly, it certainly could not have recorded only such simple content.

"Uchiha...stone tablet...Sharingan..." Uchiha Izuna frowned and thought.

Since it is related to these, then... perhaps the Uchiha clan's unique Sharingan can give him some inspiration.

After Uchiha Izuna figured it out, he no longer hesitated and decisively opened the Mangekyo.

When I looked at the stone tablet again this time, the content on it had completely changed.

Uchiha Izuna clearly knows every word, but why is it that when they are put together, Uchiha Izuna just feels incomprehensible?

Those familiar characters seemed to have suddenly turned into some incomprehensible, distorted black ghosts, wandering freely on the stone tablet.

Uchiha Izuna felt a black flash in front of his eyes, and a black kaleidoscope pattern was spinning rapidly in his eyeballs.

……

"Izuna? Izuna?"

The familiar childish voice echoed in Uchiha Izuna's ears. He came back to his senses and turned his head sharply to ask:

"What's wrong Kagamikawa?"

Senju Kagamikawa's expression became more and more worried. He stared at Uchiha Izuna's inexplicably opened Mangekyō Sharingan and the very forced and stiff smile at the corner of his lips.

"Izuna...if you're unhappy...don't laugh."

"Although Izuna is very pretty...but when she smiles like this, I feel like she's going to cry in the next second..."

Uchiha Izuna's smile completely froze on his lips.
