"Do you think I'm stupid?"
The little girl's idea sounded nice, but he had just extracted a tiny bit of Chakra. What could he even do with it?
Winning would be expected. Losing would be a total embarrassment.
Getting beaten by a six-year-old girl would be worse than getting slapped around by a monkey.
But just as Seiryū was about to refuse, the system prompt suddenly rang in his mind.
[Ding. As the future Soul King who will rule the Three Realms, the Host's legendary path must be full of challenges. The Host must not fear any challenge from a Shinigami!]
[Mission Released: Defeat challenger Ochiai Rumi!]
[Mission Reward: Bakudo #1: Sai (Restrain)!]
Seiryū: "..."
Who the heck was Ochiai Rumi?
No clue... though, it made sense if the system treated the Ninja Academy like the Shin'ō Academy and mistook Kurenai for some Bleach side character.
Not bothering to dwell on it, Seiryū instantly changed his tone, as if he hadn't just been about to say no. "But now that I think about it…"
He spoke with confidence, considering Kurenai. "Uncle Shinku said if you can extract Chakra within a few days, you're a genius. I did it in ten seconds, so I'm basically a genius among geniuses."
"If I wait too long, it won't be fair to Kurenai. She might accuse me of cheating. So, fine, I accept. We'll spar tonight!"
Oh well, since the system gave a mission, how could he refuse?
Even if the reward was just a low-level Bakudo, a gain was still a gain.
A tiny girl? How scary could she be? Even if she'd been extracting Chakra for half a year, she was still just a kid.
He'd take her down in a few minutes.
"Really?" Kurenai didn't care that Seiryū clearly looked down on her. What mattered was locking in the deal to decide who was the older sibling.
She placed her hands on her hips. "Then it's settled. No one can back out now. Father, you'll be the witness!"
Shinku glanced at Seiryū, smiled, and nodded. "Alright, I'll be the witness."
Seiryū rubbed Kurenai's head like an older brother giving a head pat. "Kurenai, just be a good little sister. Big brother will take good care of you!"
Kurenai slapped away his mischievous hand and snorted. "It's not decided yet. We'll see who wins!"
...Afternoon.
After lunch.
Seiryū continued practicing Chakra extraction in the backyard.
Feeling the Chakra flowing inside him, he rubbed his chin and muttered, "As expected, I need to build up step by step. Talent only determines the ceiling."
"Realizing that talent takes time. Just because I started ahead doesn't mean I can slack off and still get stronger…"
Probably because of his exceptional aptitude, Seiryū's Chakra extraction speed wasn't slow.
But maybe due to his body still being immature, or because it was his first time doing this, the actual amount of Chakra in his body wasn't much.
He estimated it wasn't even enough to pull off an E-rank jutsu…
Seiryū made a judgment. "I still need to let my body adjust. In the original story, Kakashi graduated at age five and was already at Genin level. There's no way he had this little Chakra…"
Understanding this, Seiryū felt more at ease. He just needed to take things one step at a time.
The system had activated and its rewards were working. That alone was enough to make him happy. He wasn't expecting instant invincibility.
The system already made it clear, he would gradually walk the path of a Soul King. One step at a time. No skipping to the top.
So Seiryū began thinking about more practical matters, like how to beat Kurenai in their spar tonight.
He had to win. Calling a little girl "older sister" was too horrifying.
In the past two months, Seiryū hadn't seen Kurenai learning any jutsu or combat techniques from Shinku. Her daily routine was mostly light training and Chakra extraction.
Her Chakra had grown steadily.
At only six years old, laying a solid foundation was more important than combat strength.
That said, Kurenai's Chakra reserves and physical strength were definitely higher than his.
But that was her only edge.
She didn't know any jutsu or real fighting techniques, so she couldn't fully use that advantage.
As for Seiryū, well, back in his previous life, he had taken martial arts classes when he was bored.
His combat technique might be shaky, but he had some real fighting experience.
Add to that his precise Chakra control, even if he didn't have much of it, that was his ace.
This match? He had it in the bag.
Just then, Shinku walked over, raising an eyebrow at Seiryū. "I've never seen you work so hard before. But overdoing it isn't good either. You've only just started learning to control Chakra. Don't overexert yourself."
Seiryū spread his hands. "I can't lose to Kurenai, right? As her older brother, I've got to save face!"
"Then why did you agree to spar with her tonight? She's been taking it seriously, trying to figure out how to beat you…"
"Pressure builds motivation. It's good for her and for me."
Shinku chuckled and teased, "I actually want to see you lose to Kurenai and call her 'older sister.' That'd be hilarious…"
Seiryū's mouth twitched. "That's not going to happen."
After a pause, he suddenly remembered something. "Oh right, Uncle Shinku, I thought of a way to use Chakra. Could you tell me if it's viable?"
Shinku looked surprised. "Oh? What kind of application?"
Seiryū explained, "Besides releasing jutsu, Chakra should also be usable for direct attacks, right? Like if I release Chakra from a point on impact when I strike, wouldn't that enhance the power?"
Shinku was visibly stunned. "You thought of that yourself?"
Of course it was possible. Tsunade, one of the Sannin, was a master of that exact kind of technique.
Seiryū nodded. "Just a random thought."
Of course, it wasn't random. As a transmigrator, Seiryū had a pretty active imagination.
And this kind of Chakra application was already shown in the original story.
Tsunade and the Hyuga Clan both used it. The only difference was their focus, Tsunade's style emphasized raw impact, while the Hyuga focused on precision targeting of Chakra points.
The reason Seiryū asked was that he had tried it earlier, but... it had no effect.
He wanted some guidance from Shinku, a Jonin.
Maybe he'd get a helpful pointer or two.
If he could grasp the basics of this technique, it would make tonight's spar even more one-sided.
Yes, Seiryū was this cautious.
Shinku took a deep breath and nodded. "It's definitely possible. Lady Tsunade, one of the Sannin, specializes in this kind of Chakra-enhanced taijutsu."
"But pulling it off isn't easy. You need precise Chakra control, perfect timing, and the right amount of Chakra output. Even I haven't completely mastered it…"
Knowing the theory and actually doing it were two different things.
Take the Rasengan, for example. The theory is just condensing Chakra into your hand, making it rotate in multiple directions while keeping it compressed.
Sounds simple, right?
But without a teacher, good luck getting anywhere with it.
