Early the next morning, the first rays of sunlight rose.
"Teacher, what is this...?"
Cangyi was the first to awaken from his chakra refinement.
Roy's haggard face wore a... strange grin.
Something about this state seemed off.
Nothing seemed to have happened last night, though.
So why was Teacher Roy like this?
"Cangyi, come here."
Seeing Uzumaki Cangyi awake, Roy's smile widened.
To Cangyi, that expression made him look exactly like a perverted old man!
Combined with their respective identities, even Cangyi, who did not fear death, subconsciously swallowed.
Still, he chose to trust Roy.
He slowly walked over.
"Your teacher developed a ninjutsu last night. It's very suitable for your current training."
"This ninjutsu can not only test your chakra control, but also measure your aptitude."
"Most importantly, it's fairly powerful."
After saying that, Roy raised his hand.
Very quickly, a mass of chakra began to gather in his palm.
A large amount of chakra formed a stream that began spinning in his hand.
"Rasengan!"
With a loud shout, Roy pressed his hand against the large tree beside him.
The tree, so thick that it took two people to encircle it, was immediately brought down by that Rasengan.
"This was... developed by you, Teacher?"
Uzumaki Cangyi looked at the fallen tree before him in shock.
After all, the Uzumaki Clan were natural sensory-type ninja.
The amount of chakra Roy had released just now was not particularly astounding.
Yet... it had been able to unleash enough force in an instant to destroy its target.
Once one mastered the technique of such a ninjutsu...
Even a Genin should be able to use it, right?
"No."
"It was developed by an old acquaintance connected to your Uzumaki Clan."
"I wonder if you've heard the name Namikaze Minato."
Roy answered frankly.
This technique
