"S–Single-hand seals?"
Inside the Akira household living room—
Shizune stared with wide eyes, completely stunned.
Beside her, Tsunade also showed clear surprise.
They watched as Akira Ren demonstrated the Mystical Palm Technique before them.
The Mystical Palm Technique was an A-rank medical ninjutsu, far from an ordinary low-level technique.
Yet he could perform it with one hand.
And at such a young age.
It was truly unbelievable.
"Tsk… what an astonishing kid…"
Tsunade stretched out her right hand.
Without hesitation, she allowed the gentle green glow of healing chakra to envelop it.
Feeling the technique personally, her expression soon changed.
Compared to her, the greatest medical ninja, Ren's mastery of the Mystical Palm Technique still had some room to improve.
But the fine chakra control he displayed proved that what he lacked was merely practical experience.
More importantly—
His Mystical Palm Technique carried an unusually powerful vitality.
Even Tsunade couldn't help but marvel.
"Ren, your chakra is very special," Tsunade said slowly.
"No wonder Nao managed to hold on until now."
The chakra inside his body—
It was almost as if the First Hokage himself had returned.
That overwhelming vitality increased the effectiveness of his Mystical Palm Technique by several times.
The only difference was—
The presence of Wood Release within it.
"Yes… but this is already the limit."
Ren sighed softly.
The old woman's body had already reached its limit.
Her life was nearing its end.
Earlier, after witnessing him formally become Tsunade's disciple, Akira Nao had wanted to personally entertain Tsunade and talk with her.
But her body could no longer endure.
After helping her back to her room, she had fallen asleep almost immediately.
At this rate—
She likely wouldn't last many more days.
"Don't think too much about it."
Tsunade gently patted Ren's head.
"You've already done more than enough."
"To be honest, even I wouldn't have been able to extend her life this long."
Looking at this genius disciple she had accepted less than a day ago—yet who had already given her countless surprises—
Her expression suddenly turned serious.
"If I'm not mistaken," Tsunade said slowly,
"Even if you were injured, you wouldn't need hand seals to heal yourself, right?"
"What?!"
Shizune froze.
"You mean he can heal his own injuries without seals?"
She stared at Ren in disbelief, then looked at Tsunade.
"Lady Tsunade… that can't be possible, right?"
"Bwee~ bwee~!"
Even the pink pig beside them squealed.
"Yes."
Ren nodded with a smile.
"Ordinary wounds heal almost instantly."
As he spoke—
He deliberately suppressed the elemental transformation ability of the Mori Mori Fruit.
Then he picked up a fruit knife from the table.
"Like this."
Seeing what he was about to do, Tsunade instinctively turned her head away.
She suffered from hemophobia.
The sight of blood would cause her body to tremble uncontrollably.
The next moment—
Ren drew the knife across his own arm.
Slash.
Bright red blood immediately emerged.
Before Shizune's shocked eyes—
The deep wound, one that should normally take ten days or even half a month to recover without medical treatment—
Began healing at a visible speed.
Within moments—
The wound completely disappeared.
Not even a scar remained.
"Incredible… the wound is gone!"
Shizune rushed over and wiped away the blood from Ren's arm.
After checking several times and confirming there was truly no scar—
She was so shocked she could hardly speak.
She stared blankly at her young, handsome junior disciple.
What kind of monster is this kid?
Then she quickly turned to Tsunade, who had deliberately looked away earlier.
"Lady Tsunade, it's fine now!"
"I thought so…"
Tsunade turned back.
Arms folded across her chest, she nodded calmly.
She wasn't too surprised.
Because her grandfather, Senju Hashirama, could also heal his wounds instantly without forming seals.
So when she sensed the overwhelming vitality in Ren's chakra—
She had already suspected he possessed a similar ability.
What Tsunade didn't know, however—
Was that Hashirama's ability to heal without seals was not because of Wood Release.
It was because he was the reincarnation of Asura Ōtsutsuki, the second son of the Sage of Six Paths.
He had inherited the Sage Body, granting him immense Yang Release power.
Ren was different.
Even without the Mori Mori Fruit—
His pure Senju bloodline meant he already had the potential to awaken Wood Release in the future.
But he lacked the overwhelming Yang Release power of Asura's chakra, meaning he normally wouldn't reach the same heights as the First Hokage.
Just like his distant cousin Kazematsuri Mei in the future—
She would awaken Wood Release as well.
But due to her limited strength, her Wood Release would be far weaker.
Even Yamato (Tenzo)—the sole survivor of Orochimaru's experiments implanting Hashirama cells into dozens of infants—was stronger than her.
Ren's instant healing, however, came from a different source.
After gaining the Mori Mori Fruit, the dormant Wood Release bloodline inside his body had effectively been awakened.
His natural Senju chakra, the rare Wood Release bloodline, and the Logia power of the Mori Mori Fruit had merged perfectly.
The fusion of these three forces created a mutation.
As a result—
He had naturally obtained perfect Yang Release power.
And as his strength continued to grow—
This unique power would only become stronger and stronger.
