Aoki Yoru watched the scene and was stunned for a moment; with his eyesight, he could tell at a glance that the Chakra in Sakura's body was at least double what it was before.
Then he turned to Tsunade in confusion: "Sakura isn't using the Strength of a Hundred Technique, is she? Why is there no diamond mark on her forehead?"
"That's a semi-finished product; it hasn't fully formed yet and is still in the nurturing stage within her body."
"Ah? In that case, won't she have to start nurturing it all over again?"
"Yeah, that idiot, why is she being so serious?" Tsunade couldn't help but sigh, holding her forehead.
She also knew that Sakura's competitive spirit had flared up and she didn't want to lose to Yui.
This was also her fault; while teaching Sakura, in order to keep her from constantly thinking about Sasuke and to stir up her competitive spirit, she had repeatedly used Yui as an example.
She also often sighed: "If only there were really no time, I would have taken Yui as a disciple as well."
She didn't expect it to make Sakura so reckless.
It seems she was overstimulated.
At this time, Sakura was panting heavily; the previous exchange of Monstrous Strength Punches had actually left her at a disadvantage, and if it continued like this, she would be the one to lose.
But she didn't want to lose.
Her Monstrous Strength Punch was taught personally by her teacher, while Yui had clearly figured it out on her own.
At first, there were some flaws, but in the battle against her, Yui was constantly refining it and gradually suppressing her.
Tsunade-sensei was watching from the side; it was one thing for her Medical Ninjutsu to be inferior, but if even her Monstrous Strength Punch was surpassed, then how could she have the face to call herself her teacher's disciple?
You should know that her teacher had high hopes for her, saying she could inherit her mantle.
"Cough, cough!"
Yui slowly climbed up from the ground; the massive impact had left her a bit breathless, but after coughing loudly a few times, she recovered.
Brushing off the dust on her body, Yui looked at Sakura, whose Chakra fluctuations had clearly increased, her eyes showing envy.
The technique just now was undoubtedly the Strength of a Hundred Technique.
That was the exclusive Ninjutsu of the Fifth Hokage; although Tsunade said she would teach it to her as long as she met her requirements, her Medical Ninjutsu was still some distance away from Tsunade's.
Unlike Sakura, who was taught personally.
She then shook her head to clear her mind, mocking herself for being greedy.
Being Kakashi's disciple was already a blessing from several lifetimes.
While other teams were working hard to accumulate mission points to exchange for Ninjutsu, Kakashi had given her the A-rank Mystical Palm Technique as soon as he acted, and even recommended her to the hospital's vice-director to look after her.
Moreover, the Ninjutsu she possessed, except for a few family heirlooms, were all taught by Kakashi without reservation.
He even unhesitatingly passed on the Lightning Cutter to her when she hit a bottleneck in developing Lightning Style Chakra.
To put it bluntly, without Kakashi, who knows how long it would have taken the three of them in their team to reach their current heights.
"Whew—"
Yui let out a long breath and concentrated her gaze on Sakura.
Then, she mobilized her Chakra and took a deep breath, with wisps of breeze emerging from her nostrils.
"Wind Breathing: Monstrous Strength Punch!"
Immediately, a breeze emanated from her fist, and pale green Wind Release Chakra wrapped around it, making a faint "hissing" sound as it cut through the air.
Tsunade's eyes narrowed at the edge of the field; she could clearly feel that Yui's Monstrous Strength Punch had actually integrated Wind Style Chakra nature transformation.
The wind from the punch carried a sharp cutting sensation, completely different from the pure explosive power of Monstrous Strength.
"Not bad, right?"
Tsunade showed a look of appreciation; adding Wind Style to the Monstrous Strength Punch wasn't as simple as one plus one equals two; the difficulty increased geometrically.
The transformation of the Wind Style nature was used with pure mastery.
Sakura also immediately noticed that unusual sharpness.
Her expression turned solemn, and she no longer held back, instantly concentrating her entire body's Chakra into her right fist, where pale green Chakra light pulsed violently.
"Bang—!"
The two fists collided fiercely, and the dual power of Wind Release and Monstrous Strength exploded, a visible violent airwave sweeping out from the two of them as the center.
The ground beneath their feet instantly cracked into spiderweb-like fissures, rubble and dirt were sent flying by the airwave, and nearby trees were snapped in half by the gale, their branches and leaves torn to shreds.
And the Wind Release Chakra on Yui's fist leaked through the gaps of the collision, sharp wind blades grazing Sakura's arm.
Instantly tearing her sleeve and cutting several fine wounds on her skin, droplets of blood immediately seeping out.
Sakura didn't care; under the effect of the Strength of a Hundred Technique, the wounds healed instantly.
Yui looked at Sakura's arm, which was as white as dawn, her pupils shrinking; this technique was truly unreasonable.
"Boom—Boom!"
In the field, the two figures blurred as they began a series of close-quarters exchanges.
Sakura's Monstrous Strength Punch was heavy and fierce, pale green Chakra exploding on her fist, each strike carrying immense weight.
Yui could only rely on Wind Release Chakra to tightly wrap her fist, using the cutting of the wind blades and wind pressure as a buffer to barely withstand her attacks.
Gradually, Sakura's attack power weakened.
This was normal; the Chakra stored using the Strength of a Hundred Technique was almost exhausted.
During a fist collision, Sakura took the opportunity to disengage from the battle.
"Huff, huff, huff—"
She panted heavily, blood dripping from her right arm; she no longer dared to waste Chakra on healing.
Outside the field, Tsunade and Jiraiya watched with serious expressions; they hadn't expected the development to go like this, which was far from what they had anticipated.
"This little girl is not simple! Kakashi, you've taught a good disciple," Jiraiya couldn't help but sigh.
He could see that Yui hadn't used her full strength, since she had been fighting with Monstrous Strength Punch from the start.
To be able to use Wind Style nature transformation to such perfection, she was definitely not simple in terms of Ninjutsu.
Combined with Tsunade's praise for Yui's Medical Ninjutsu, this little girl might have already stepped into that realm.
It's truly amazing; not only Aoki Yoru, but even that little girl has caught up?
Then, Jiraiya looked at Kenta, who was leisurely fighting against Naruto's thousands of Shadow Clones in the distance, and thought to himself, 'Is that child as well?'
Hearing Jiraiya's praise, Kakashi sheepishly rubbed the back of his head, "You flatter them, it's all their own talent."
Kakashi truly believed this in his heart; teaching the three of them didn't take much effort.
Aoki Yoru went without saying; a human Sharingan, he could replicate any Ninjutsu after seeing it once.
Yui and Kenta also learned extremely fast, and they both had their own clear plans.
He only taught them as a teacher when they needed help.
To be honest, the effort he spent leading Team 6 for two years wasn't as much as the few months he spent leading Team 7.
In the field, Sakura looked at Yui, her gaze narrowing as if she had made a decision.
No matter what, she didn't want to lose.
She dipped her left finger in the blood on her arm and pressed her hands together.
"Hey, hey, hey, is it necessary to go this far? Aren't you going to stop her?"
Sakura's hand signs clearly indicated a Summoning Jutsu; she was going to summon Katsuyu!
Tsunade showed a gratified smile: "I didn't expect Sakura to have this side to her. This is good; let her fight with all her might. It's essential for her growth."
"And while we're at it, let's see how much this girl Yui is hiding."
