Konoha: Unable to learn ninjutsu, they had to develop their own.

They stopped on a small hill outside Tanabata Street.

He has other sources of honor and money; being a Jonin is more of a burden to him.

At first, they were very easy to fool, completely innocent, but now they understand some of his tricks.

"I also need to go!"

Sasuke nodded.

"it is good."

Jonin are already high-ranking members of each village, and many ninjas spend their entire lives without ever being promoted from Special Jonin to Jonin.

"Who's winning?"

Finally, Naruto stammered, "This, this is, arm wrestling?"

Kids these days are not easy to fool.

Chiba gathers his energy and concentrates his mind.

"I've also learned superhuman strength techniques."

"Hehe, the same technique can have different effects depending on how it's used by different people."

As Tsunade spoke, she suddenly exerted her strength.

boom!

A burst of chakra energy exploded out, causing cracks to appear in the rocks below.

The veins in their arms were bulging, suggesting they were evenly matched.

Tsunade continuously increased her chakra.

but.

She noticed that the other person's strength was gradually increasing.

So strong!

Chiba actually mastered the superhuman strength technique.

How long has it been?

Tsunade did a quick mental calculation: at most, it would take less than half a month, maybe even less—

According to Jiraiya and Chiba's own descriptions, this child is quite busy in Konoha.

Great!

Tsunade sighed inwardly.

She focused her energy and concentrated most of her chakra into her arm. In an instant, her power doubled.

"Evenly matched! Chiba-kun is amazing!"

"I'm surprised," Shizune said.

The last time I saw Lady Tsunade in such a stalemate was when she fought the Raikage, and the Raikage was even slightly outmatched in strength.

Chiba is truly almost the same.

"Both of them are very strong!"

Sasuke has awakened his Sharingan, and the flow of chakra between the two is visible in his eyes—

What terrifying chakra manipulation ability!

Both of them used their chakra and strength to the limit.

Even if you understand how the technique works, you still can't learn it.

Jiraiya frowned.

condition……

Something is wrong!

Chiba looked up.

Did you use force?

"???"

Tsunade's eyes widened, her large watermelon bobbing up and down, her other hand already itching to strike, as if she was about to swing it down at any moment.

Jiraiya opened his mouth wide and remained silent for a long time.

This?

That's an insult!

Tsunade's strength is well-known, and since it's a contest of strength, she wouldn't hold back. Was that kid genuinely ignorant or was he deliberately provoking her?

"Kid, try and beat me!"

Tsunade flew into a rage, her arm muscles bulging—

She had already pushed her superhuman strength to its limit, and she would have to heal her injuries herself with medical ninjutsu. However, the next moment, Chiba's strength suddenly increased significantly.

boom!

The rocks below were shattered.

"I didn't control my strength well, and the duel stage is ruined. I admit defeat."

"No, I lost."

Tsunade raised an eyebrow, refusing Chiba's offer of help, and instead admitted defeat.

Just a moment ago, she felt Chiba's strength suddenly increase two or three times, and even without that explosive power, Chiba's strength was still comparable to hers.

The scariest thing is——

The other person is not even fourteen years old.

This means that Chiba still has the potential to grow.

He will only become stronger in the future.

Tsunade stood up and said with emotion, "With you all in Konoha's future, I believe Grandpa and Second Grandpa will be very at ease when they return to the Underworld."

"It's too early to talk about that; I'm not even fourteen yet."

Chiba stood up, kicked his foot, and the stone below turned into pieces the size of fingernails.

To avoid shattering the rock, they distributed their force evenly throughout it.

It is intact on the outside, but its interior has long been completely destroyed.

Naruto was dumbfounded.

Sasuke already knew the outcome, so he wasn't too surprised. As for Jiraiya...

He was thinking—

Even if Chiba created that chakra shield, it's too cheating to switch Sage Mode on and off instantly.

How could it be so powerful?

and.

In a contest of strength, is using a celestial ability not considered cheating?

Jiraiya thought for a few seconds and decided not to provoke this bad luck.

He felt that if he spoke up, Tsunade might actually reprimand him...

Why can't you turn it on instantly?

Jiraiya pondered silently.

In the end, he stopped thinking about it.

More important than anything else is learning Chiba's chakra shield as soon as possible.

Tsunade seemed lost in thought. On her way back, she was still wondering how Chiba had managed to do that. When she returned to Tanabata Street, a possibility came to her mind.

"You've maximized the use of your muscle strength?"

"Yes, under extreme conditions, my control over my body and strength is close to the open state of the Eight Gates."

Chiba said.

Upon hearing this, Tsunade couldn't help but exclaim, "Amazing! I've had that thought too, but I didn't do much research afterward. All I did was fight war..."

"Indeed, this technique is quite time-consuming. If you had spent time on it, you might not have reached the pinnacle of the medical field later on, and we, the younger generation, would not have been able to see the current medical ninja system."

Chiba said.

Tsunade nodded in agreement.

She had so much to do—war, medical ninjutsu, and reforms of medical ninjas—that she simply didn't have time to study them at the time.

As for what happened later...

She no longer needs that kind of physical skill.

One reason is that Tsunade herself doesn't need it, and the other is that it's very difficult for ordinary medical ninjas to learn such advanced taijutsu.

After weighing the options, she focused her attention on medical ninjutsu.

Tsunade initially felt like she had met a kindred spirit, and was even a little excited. She blurted out, "Wait, you've studied medical ninjutsu?"

"No, I just studied in a medical class for a period of time."

Chiba replied.

Shizune caught up from behind, first surprised that Chiba had studied medical knowledge, then asked Sasuke, "So how long did he study it?"

Sasuke glanced at it and whispered, "You wouldn't want to know."

"why?"

"Chiba-senpai graduated early and then studied in the medical class for two or three months. But actually, from the first month onwards, he became famous throughout the village for creating the ninjutsu of chakra needles in the medical class."

Sasuke said calmly.
