Shangguan Yue channeled chakra into the fish's body, sensing it with meticulous care.
...Time Skip...
"Whew, damn it, no, this is too hard. As expected, I'm still a loser; I can't even copy the answer when it's given to me. Where are the cells the scroll mentioned? I can't find them."
The spread-out scroll clearly stated: first, locate the active cells, then use chakra to stimulate the cell core to promote cell division...
But where were the cells? Among this massive pile of cells, which one was the so-called active cell?
"Even though you drew illustrations, but, but... I can't see them! How am I supposed to know if the cell I'm sensing is the active one you're talking about? Wait... see? That's right, I have Divine Sense."
Shangguan Yue hurriedly attached his spiritual energy to his chakra, entering the fish's body along with it.
"Wow, I didn't expect my Divine Sense to be able to perceive things at a microscopic level under the influence of chakra."
Watching the cells drift past him, Shangguan Yue felt incredibly fascinated.
"Holy crap, so there you are! So this is what you feel like—an active cell."
Shangguan Yue manipulated his chakra to hover before the active cell, observing it closely.
Shangguan Yue rubbed his hands together. "Alright, let's begin."
"Pop~ Ouch, used too much force and burst it. Next."
"Pop~ Sigh, burst again."
Shangguan Yue was like a brute, charging recklessly through the cells. Before long, he noticed the cells' movements slowing down.
"Huh? What's going on?"
Shangguan Yue snapped back to reality and looked at the fish before him; its eyes had rolled back, and it was completely motionless.
"Haha, my bad, my bad."
Shangguan Yue chuckled awkwardly, punched a small pit into the ground, tossed the fish in, and buried it.
He looked at the fish tank. "Hmm, there are still plenty left. It shouldn't be a problem."
...Time Skip...
"Whew, this isn't hard at all. It's a piece of cake."
Shangguan Yue looked at the lively little fish jumping in his palm and finally breathed a sigh of relief, wiping the sweat from his forehead.
If not for the uneven, pockmarked ground, one might have almost believed his nonsense—especially considering the number of pits, which clearly indicated he had bought more replacements.
"Exhausted. Time to go back and sleep."
Shangguan Yue stood up and stretched, feeling sore all over and lacking any energy.
"Forget it, I'll just sleep here. She's going to be my woman anyway, why bother going home?"
He rubbed his temples. "My spiritual energy was nearly drained this time. I need to be more careful next time; I was getting obsessed."
Shangguan Yue walked into Tsunade's house, made his way to the bedroom with practiced ease, and collapsed into sleep.
The night passed without incident until the sun was high in the sky the next day.
"Onii-san, wake up!"
"Knock, knock, knock."
"I'm coming in!"
"Click." The door swung open. Shangguan Yue was still fast asleep, scratching his butt and exposing a thigh.
"Sister, you're still sleeping? Get up!"
Senju Nawaki grabbed a corner of the blanket and pulled hard. "Ehh!!! Who are you?"
"Who is it?"
Shangguan Yue's morning grumpiness flared up as he opened his eyes to look at the person disturbing his dream.
"Who are you?"
"This is my house. Who are you?"
"Your house? Are you Senju Nawaki?"
"Yeah, who are you? Why are you sleeping in my sister's bed?"
"Heh heh heh, I'm already sleeping in your sister's bed—take a guess what kind of relationship I have with her?"
Nawaki tilted his head in thought. "You look about the same age as me, what kind of relationship could you have with my sister? Her child? No. Her relative? No, I'm her only brother. A friend? But the age gap is too big."
A boyfriend? Even less likely; you're far too young.
So, there is only one truth: you're a thief!
Tell me, how did you get in here?
"Oh, my dear Master Nawaki, you're far too clever. Even if I were a thief, do you really think someone as small as me could sneak into the Senju Compound and make it all the way to your sister's bedroom?"
"I don't care about that. Take this!" Senju Nawaki swung his fist toward Shangguan Yue.
"Hey, if you keep this up, I won't be so polite anymore." Shangguan Yue easily dodged Nawaki's punches.
"Bring it on! I want you to be impolite. Let me see just how much skill you actually have."
"Let's head outside; this isn't the place for a fight." Shangguan Yue vaulted through the window and stood outside, watching as Nawaki followed close behind.
He extended a hand and beckoned, "Come on."
I just learned Healing Jutsu yesterday and my control over chakra has improved; I'll use this Senju Nawaki to test the waters.
Haha, sorry about this, buddy. Even if you and my sister have a close relationship, I just got back from my teacher's place, so I'm going to use you for some practice.
Both of them secretly viewed the other as a whetstone to test what they had learned.
Nawaki was hot-headed; without looking for any openings, he charged forward with his fists raised. After a brief exchange of blows, they both gained an understanding of the other's strength.
This Nawaki has incredible strength, but I'm not bad either. It's a pity I obtained the Sage Body so late; otherwise, in terms of physical constitution, I would have long since surpassed my peers by a wide margin.
It seems a physical confrontation won't yield a winner anytime soon.
After trading another punch, Nawaki used the momentum to slide a distance away, standing opposite Shangguan Yue.
"I'm going to use ninjutsu now, so be careful."
"Don't worry, bring it on."
Nawaki quickly formed hand seals and shouted, "Water Release: Water Wave."
