Ninjutsu without Hand Seals?!

Konoha Camp.

After Uchiha Yoru and Tsunade returned to the camp from the back mountain together, quite a few shinobi who saw this began discussing it in private.

"Good heavens, I heard it was at the waterfall in the back mountain."

"Hmph! What Uchiha hard bones?"

"Tch, you're just jealous, aren't you?"

With Tsunade's formidable strength, her senses were naturally sharper. Especially after what had just happened, she deliberately listened in.

Given Tsunade's current strength, if she wanted to eavesdrop, how many shinobi in the camp could avoid being noticed?

Sure enough!

After hearing the shinobi gossiping in private, Tsunade felt even more stifled. With her forthright personality, she did not care much about such rumors.

But what about the sensitive and proud Uchiha?

Without making it obvious, she glanced at Uchiha Yoru, who had returned with her.

Uchiha Yoru looked calm, a gentle smile on his face, as though none of those rumors had hurt him at all.

But could that really be possible?

Perhaps other shinobi would not care, but this was an Uchiha!

Stubbornness and pride were engraved in their bones.

"Hey, hey. Since you've already mastered the Mystical Palm Technique, that's not bad. You deserve some praise. But what about the Summoning Jutsu?"

Inside the tent, while Tsunade thoroughly examined Uchiha Yoru's body, she sternly said this, as though reminding him that her Katsuyu summoning beast came from one of the Three Great Sage Locations and he had better not fail to appreciate it.

Facing Tsunade's stern rebuke, Uchiha Yoru felt as though she had already grown accustomed to playing the roles of teacher, older sister, and commander. Before him, she always seemed to use one of those tones.

"Captain Tsunade, do you mean Lady Katsuyu?"

Uchiha Yoru chuckled. He raised his hand and lightly slapped the hospital bed, and a puff of white smoke the size of a watermelon immediately appeared.

As the smoke dispersed, it revealed a soft blue-and-white slug Summoning Beast named Katsuyu.

"Yoru, Lady Tsunade."

A soft, gentle voice rang out. She was also the most good-natured of Summoning Beasts. Just hearing her voice put Uchiha Yoru in a good mood, and he smiled and nodded.

"Hello, Lady Katsuyu."

When Tsunade saw Katsuyu, the corner of her eye twitched. She snorted irritably.

"Brat, you've gone too far with those Shadow Clones these past three months."

As Tsunade barked orders, Katsuyu noticed the injury on Uchiha Yoru's palm and gently wriggled forward.

His arm and palm were met with a cool, soft sensation, as though they had been submerged in jelly. Uchiha Yoru could not help revealing a comfortable expression.

"Thank you, Lady Katsuyu."

Uchiha Yoru replied with a smile. He knew very well that this kind-tempered Summoning Beast had lived for an unknown length of time and was even called the lowest-ranking sage in Tsunade's presence.

Seeing this, Tsunade clicked her tongue and sat down in a chair nearby, glaring as she began to scold him.

"Brat, you're being far too reckless. Your Ninjutsu already concentrates Chakra at an extremely high density, which is very dangerous. Coupled with the high-speed rotation and friction, it puts enormous strain on your palm.

"And three consecutive months of high-intensity Chakra output have left the meridians in your right arm severely fatigued. Keep this up, and you'll cripple that hand."

Tsunade seemed accustomed to lecturing this brat, Uchiha Yoru, especially while wearing a stern expression and using the tone of a commander or a teacher who was a guiding jonin.

After listening to every word with a gentle and sincere expression, Uchiha Yoru slowly raised his head and laughed in a tone nearly as gentle as Katsuyu's.

"Thank you for your concern, Captain Tsunade. But this Ninjutsu has already completed its training."

Concern!?

Those two words caught Tsunade off guard, and then she snorted.

Uchiha Yoru, meanwhile, looked like an obedient student, ready to accept another reprimand at any time.

He wanted Tsunade to grow accustomed to, or rather, confront the concern she now had for him, rather than treating it as an instinctive concern she was unaware of.

Psychologically speaking, Tsunade's instinctive concern had felt like something natural and unquestionable. But once Uchiha Yoru said it aloud, combined with the earlier rumors—

Those words would feel different in Tsunade's heart, giving her the illusion that she really did care about an Uchiha!

Acting on instinct without putting her heart into it was one thing. Once she did put her heart into it, that would mark the beginning of a change in its nature.

"Tch! Don't flatter yourself!"

At that moment, Tsunade seemed to notice that her concern was unusual. She put on a stern face and snorted. After looking at Uchiha Yoru's injured palm, she began changing the subject.

Even she did not realize that her attitude toward this brat before her seemed to be becoming more heartfelt!

"You brat, I really don't know what goes on in that head of yours. You actually managed to devise this Ninjutsu."

There was no shortage of geniuses in the Shinobi World who created their own Ninjutsu. In fact, there were many of them. After all, had not the countless Ninjutsu in the Shinobi World all been created by someone?

But A-rank Ninjutsu already counted as an ultimate technique for jonin. If a jonin possessed even one A-rank Ninjutsu, it was practically a trump card.

One could imagine just how valuable A-rank Ninjutsu was.

Faced with Tsunade instinctively changing the subject, Uchiha Yoru could not have been happier. Only when this feeling was buried in her heart would it slowly ferment and change.

"Captain Tsunade, the inspiration for this Ninjutsu came from Kushina."

"Kushina?"

This time, Tsunade genuinely looked curious and confused. Uchiha Yoru smiled and nodded.

"That's right. When Kushina went berserk three months ago, the terrifying attack of that Tailed Beast Ball... My Ninjutsu cannot compare to it, but from the formation of the Tailed Beast Ball to its release, it seemed to be nothing more than pure compressed Chakra, without any complicated hand seals."

"Then I began to wonder how a shinobi could release this kind of Ninjutsu through pure Chakra manipulation. After several experiments, I reached a conclusion: rotation, compression, and stability. As long as those three key points were ensured—

"And as long as the shinobi could steadily maintain Chakra output, this A-rank Ninjutsu without hand seals came into being."

After hearing the inspiration behind Uchiha Yoru's self-created Ninjutsu, Tsunade suddenly understood.

"Imitating a Tailed Beast Ball? It really does resemble one. But when you said pure Chakra, without complicated hand seals, did you mean...?"

Tsunade was a shinobi herself, so she naturally possessed curiosity and a desire to explore all kinds of Ninjutsu, especially one created by drawing on a Jinchuriki's Tailed Beast Ball.

Because of her background, few in the entire Shinobi World could rival Tsunade in her foundation of Ninjutsu knowledge. Thus, there were very few Ninjutsu capable of arousing her inner curiosity.

It was precisely because Uchiha Yoru said he had drawn inspiration from the Tailed Beast Ball that she became interested.

"That's right. It is purely Chakra shape manipulation. It contains no Chakra nature transformation, and there are no complicated hand seals."

As he spoke of his own Ninjutsu, Uchiha Yoru looked as though he had received approval. He happily raised his palm, and before Tsunade's astonished eyes, a spherical mass of azure Chakra appeared.

"N-No hand seals Ninjutsu!"

Tsunade was filled with shock. She knew this brat had recently been developing some kind of Ninjutsu, but the pride of the Senju Clan meant she naturally would not secretly spy on him.

Thus, she only knew a little. Her curiosity had merely been stirred because it was connected to a Tailed Beast. But at this moment, seeing Uchiha Yoru release it with a simple lift of his hand—

And without any hand seals, Tsunade was truly stunned.

What did an A-rank Ninjutsu without hand seals represent?

Especially with her insight, she could clearly see the power of this instantly cast Ninjutsu.

If someone ambushed him at close range, instantly casting this Ninjutsu would be enough to counterattack. With such power, ordinary Ninjutsu and armor could not block it at all.

Just then, a hissing sound suddenly reached her ears. Tsunade's expression changed, and she snorted irritably.

"Orochimaru, since when did you become like Jiraiya?"

The next moment, Orochimaru's uniquely hoarse yet magnetic, charming laughter rang out.
