The next day.
Early in the morning, Ren had already gotten up for physical training. After sweating through an intense workout, he stood there—
Under the astonished gazes of Uzumaki Nanako and Karin, he directly created five wooden clones.
"Wood Release: Wood Clone Technique!"
He tossed a ninjutsu scroll to each clone.
Each one was assigned to practice various ninjutsu of a specific chakra nature.
"Wind Release: Wind Cutter!"
"Lightning Release: False Darkness!"
"Earth Release: Earth-Style Rampart!"
…
Soon, thunderous explosions rang out one after another.
Dazzling ninjutsu of all colors flashed brilliantly.
The already ruined wasteland was bombarded relentlessly, becoming even more unrecognizable.
"So amazing…"
Karin was completely stunned.
"Ren, your chakra reserves are getting more and more ridiculous!"
Standing nearby, Shizune couldn't help but marvel.
"I thought you were only letting them train chakra nature transformation, but you're actually practicing ninjutsu directly…"
"I've already perfectly mastered the nature transformations of the five chakra attributes—Wind, Lightning, Fire, Water, and Earth."
Ren shrugged.
"Continuing to train them won't have much meaning anymore."
"If I want to improve further, I can only slowly grow stronger through practicing those ninjutsu or through intense battles."
He then looked at Tsunade and said with a smile,
"Alright, Tsunade-nee, let's start learning medical ninjutsu!"
"Mm."
Tsunade nodded.
She had already grown numb to Ren's outrageous performances.
This child was a monster that simply couldn't be judged by common sense.
She was certain that even the legendary First Hokage and Uchiha Madara, who had once joined forces to pacify the chaotic ninja world, would absolutely not have possessed such exaggerated strength at Ren's current age.
They would have been completely crushed by him.
Looking at Karin, whose eyes were filled with admiration, Ren turned to Shizune and said with a smile,
"Shizune-senpai, if you have time, could you teach Karin the basic Three Body Techniques?"
"Her talent is very good. Yesterday I only taught her how to extract chakra and how to use it, and she mastered it very quickly."
It had to be said—
Karin truly was a genius.
Under Ren's guidance yesterday, after repeated attempts, she quickly managed to extract chakra.
Having just turned seven, as a descendant of the Uzumaki clan, she couldn't compare to a monster like Ren, but her innate chakra far exceeded that of ordinary people.
As long as she was willing to work hard,
it definitely wasn't too late.
"Oh? Really?"
Shizune looked at Karin in surprise, then smiled and nodded.
"Then leave it to me."
"Really? That's great… Thank you very much!"
Karin was overjoyed.
After seeing those gorgeous and dazzling ninjutsu, how could she possibly not want to learn them?
Beside her, Uzumaki Nanako—whose face was still somewhat pale but whose condition had improved a lot after Tsunade's treatment—felt extremely happy for her daughter.
After all, in this chaotic ninja world, only those who possessed strength could survive properly.
Before, there had simply been no opportunity.
Now that someone was willing to teach Karin, she couldn't be happier.
Naturally, she wouldn't stop it.
"Earth Release: Earth-Style Fortress Wall!"
Before long—
A huge commotion erupted outside.
Rumble…
The entire ruin trembled violently.
The ground split apart as if sliced in half, suddenly breaking straight down the middle.
On the other side, the terrain rapidly rose at a speed visible to the naked eye.
In the blink of an eye, it formed a massive earthen wall over a hundred meters long.
A truly magnificent sight.
"Water Release: Waterfall Basin Technique!"
Almost at the same time,
another one of Ren's wooden clones had already completed the hand seals.
Crash—
A massive torrent of water surged out.
It poured down endlessly from above,
turning into a huge waterfall.
The scene was breathtaking.
And in the low ground beneath the waterfall,
a large pool rapidly formed before their eyes.
"Fire Release: Great Dragon Fire Technique!"
The clone responsible for training Fire Release rapidly formed hand seals.
Blazing Fire Release chakra gathered in his mouth.
Then he suddenly spat it out.
Whoosh—
A blazing flame shot forward,
transforming into the head of a massive fire dragon. The sky itself seemed dyed red.
Waves of scorching heat rushed outward.
"Roar—!"
The fire dragon roared fiercely,
and slammed violently into the water pool.
Boom! Boom!
Rolling heat waves exploded outward.
The enormous pool was blasted into chaos.
Even the huge waterfall was nearly cut off as the water within was instantly evaporated.
The ground turned pitch black from the burning, cracked and scorched.
…
This shocking scene stunned not only Uzumaki Nanako and Karin—
Even Shizune, who already understood Ren's strength, was left dumbfounded.
"Tsk tsk… your progress really is fast, kid."
Inside the wooden house,
Tsunade was teaching Ren medical knowledge.
Watching the scene outside through the window, she chuckled lightly and exclaimed,
"You're becoming more and more proficient with the Five Nature ninjutsu."
"I believe it won't be long before your mastery of the five elemental releases surpasses that old man, the Third Hokage."
"Really?"
Ren's expression remained calm,
but his tone carried a hint of teasing.
"I'm quite interested in surpassing the 'strongest' Hokage of all generations."
"You brat…"
Tsunade couldn't help but laugh helplessly.
But to be fair, the Third Hokage's shamelessness did leave her somewhat speechless.
He actually dared to write himself into textbooks as the strongest Hokage in history.
It was simply laughable.
"It's just a pity that we don't know whether you'll be able to master the Sage Art of Shikkotsu Forest in the future…"
It wasn't that Tsunade doubted Ren's talent.
It was just that the requirements for Shikkotsu Forest's Sage Art were too abnormal.
Only someone with a peaceful, detached temperament like her grandmother Uzumaki Mito might be able to master it.
"Sage Art, huh?"
Ren raised an eyebrow and asked curiously,
"Tsunade-nee, I remember that among the Wood Release scrolls left by the First Hokage, there are indeed forbidden techniques at the Sage Art level. Did his Sage Art originate from Shikkotsu Forest?"
He was indeed curious.
The First Hokage possessed the same ability as him—able to instantly enter Sage Mode.
Combined with his enormous chakra reserves, it was practically equivalent to an endless-duration Sage Mode.
"No."
Tsunade shook her head and said directly,
"The First Hokage never signed a contract with Shikkotsu Forest. The one who formed a contract with Shikkotsu Forest was my grandmother, Uzumaki Mito."
She gently rubbed Ren's head, smiling with expectation.
"The First Hokage's Sage Art was created by improving and further perfecting the Sage Arts of the two great sacred lands—Shikkotsu Forest and Mount Myoboku."
"If it's you, maybe you'll be able to achieve it in the future."
Ren simply smiled without saying anything.
Sage Art?
I've always been able to use it.
