"Wood Release: Four Pillars Prison!"
"Wood Release: Wood Locking Wall!"
"Wood Release: Thorn Killing Technique!"
Boom… Boom…
Having obtained the First Hokage's Wood Release, Tsunade was full of energy. She ignored Akira Ren, Shizune, and the others and enthusiastically practiced various Wood Release ninjutsu nonstop.
Meanwhile, Karin had also undergone astonishing changes.
Not only had her chakra reserves increased dramatically, but golden chakra chains began emerging from her back, dancing in the air.
"Eh?"
Karin looked surprised.
"Is this Adamantine Sealing Chains?"
She found she could control these chakra chains at will.
"That's right, this is the Uzumaki clan's Adamantine Sealing Chains…"
Akira examined the chains extending from Karin and nodded with a smile.
"They can be used to bind or attack enemies, and can also form barriers for defense or to trap targets!"
"If you become strong enough, you can even restrain a Tailed Beast and prevent it from breaking free!"
Hearing this, Karin was overjoyed.
As Tsunade's disciple, and with Akira and Shizune teaching her, she naturally knew just how powerful Tailed Beasts were.
This meant that as long as she trained hard, she might one day be able to bind or even seal a Tailed Beast.
"That's amazing!"
"And that's not all…"
Akira patted Karin's head and smiled.
"Your chakra affinities before were only Water and Earth, plus the more special Yin and Yang, right?"
"Now you should possess all seven chakra natures: Wind, Lightning, Water, Fire, Earth, Yin, and Yang!"
As he spoke, he handed her a chakra test paper.
"Try it and you'll see!"
"Really?"
Not only the eager Karin, but even Shizune, who was standing nearby, came over curiously.
The moment Karin channeled her chakra into the test paper—
The entire sheet silently split in half as if cut by something.
Then, on the left half, part of it burst into flames while another part became wet.
On the right half, part wrinkled up while another part crumbled into pieces.
"Wind, Lightning, Water, Fire, Earth—all of them!"
Shizune's eyes widened.
"You really have all natures!"
"Awesome!"
Karin jumped up excitedly, overjoyed.
This meant she could master ninjutsu of all chakra natures, just like Akira Ren.
Last time, Akira Ren's Five Release: Great Serial Bullet technique had been incredibly powerful.
Even one of the Sannin, "Wild Ghost" Jiraiya, and the giant summoning beast Gamabunta from Mount Myōboku couldn't block it together.
That scene had left a deep impression on her.
"Akira Ren, I want to learn that Five Release: Great Serial Bullet technique!"
Karin clenched her little fists, looking at him with eyes full of expectation.
"Alright, if you want to learn it, I'll teach you…"
Akira chuckled and patted her head.
"But this technique isn't something you can easily master just because you have all the natures. It requires a lot more effort…"
The true Five Release: Great Serial Bullet wasn't as simple as creating a few shadow clones and having them each use a different nature.
First, one had to completely master the nature transformations of all five elements and maintain the exact same chakra ratio to combine them effectively into a true composite ninjutsu with power far greater than the sum of its parts.
However, if Karin could master Sage Mode in the future and use a Sage Art version of the technique, its power would be truly terrifying.
"I'll work hard!"
Karin nodded repeatedly.
Akira turned to Shizune and asked with a smile,
"Senior Sister Shizune, how do you feel now?"
Swish!
Shizune smiled slightly and formed hand seals.
The next moment, she suddenly vanished from her spot.
In an instant, she reappeared behind Akira and Karin like an afterimage.
Swish… Swish…
Her figure moved at incredible speed, constantly flickering.
In the blink of an eye, she had dashed dozens of meters away.
Chakra gathered in her fist as she punched forward fiercely.
Boom! Boom!
The ground shattered.
Smoke and dust rolled, and rocks flew everywhere.
Everything within a ten-meter radius collapsed.
It was so shocking that even Tsunade, who was happily practicing Wood Release, turned to look, her eyes narrowing.
"That speed… Shizune has really obtained an incredible bloodline limit!"
She had to admit that Shizune's increasingly proficient Strange Strength Fist, combined with Swift Release's terrifying speed, would be extremely fearsome.
Too fast to react to, nearly impossible to defend against.
If a strike landed, even a powerful enemy would be either killed or severely injured.
Moreover, it was said that if Swift Release was trained to its peak, the user could move at speeds approaching the speed of light—an extremely exaggerated ability that far surpassed ordinary Body Flicker Techniques.
Swish!
Shizune flashed back in front of Karin and Akira like lightning.
"So cool, Senior Sister Shizune…"
Karin's eyes sparkled with admiration.
"I feel like I didn't just gain the Swift Release bloodline limit—my neural reaction speed has also improved dramatically…"
Shizune said in pleasant surprise.
She looked at Akira incredulously.
"And I seem to have gained sensing abilities too. My chakra reserves have increased a lot, and they're still slowly growing!"
She had also discovered that her neural reflexes had become much sharper.
Otherwise, she would never have been able to control such astonishing speeds.
Having a fairly strong sensing ability that let her directly perceive others' chakra made Shizune extremely happy as she looked at Akira Ren.
"Thank you so much, Akira Ren…"
This gift was incredibly valuable.
She had originally thought she would only gain Swift Release and increased chakra.
She never expected there would be so many additional benefits.
"Because I also added the genes of the Hōko clan into your fruit, the benefits you received aren't limited to just Swift Release…"
Akira explained with a smile.
It was said that the Hōko clan not only had massive chakra reserves but also possessed fairly strong sensing abilities.
Their powers were quite similar to the Uzumaki clan's, though they lacked the Uzumaki's powerful sealing techniques.
"Eh?"
"Hōko clan?"
Both Karin and Shizune were surprised.
They had never heard of such a clan existing in the ninja world.
"The Hōko clan was a powerful group during the Warring States Period. They were allies of the Uchiha clan and bitter enemies of the Senju clan…"
Tsunade walked over and explained to Shizune and Karin.
"Legend has it that long ago, the Hōko clan was founded by traitors who split off from our Senju clan. In a way, they are also distant relatives of both the Senju and Uzumaki."
"Later, they were wiped out by the combined forces of the Senju, Uzumaki, and Sarutobi clans!"
"I never expected Danzo to even have Hōko clan corpses in his collection!"
"It looks like they were survivors from that clan!"
