After lunch, hearing that Tsunade planned to start Minato's training immediately, Jiraiya and Orochimaru left together.
For a ninja, training involves personal information about their abilities, which directly impacts their survival. Therefore, it's a very private matter.
Unless you are extremely close, disturbing someone's training is considered very rude.
Even seven-year-old Nawaki understood this. After greeting Tsunade, he went out to play with his friends.
Tsunade took Minato back home. She dug out several scrolls as thick as tree trunks and piled them up in front of him like she was stocking up for the apocalypse.
"Are all of these Wood Style Jutsus?"
Minato looked at the stack, which was taller than him, and his eye twitched.
"No, these are the heritage Jutsus of the Senju clan. It's not just Wood Style. Remember what you said earlier? You've already tested your chakra natures. So you must know something about chakra characteristics, right?"
Tsunade looked at Minato, testing him.
"Characteristics... Chakra has uniqueness, heredity, and sociality."
"Uniqueness means everyone's chakra signature is different. Heredity means bloodline inheritance; children usually inherit the chakra natures of their parents or ancestors."
Minato thought for a moment and continued, "Sociality refers to how chakra natures differ greatly among people in different regions, possibly influenced by social or environmental factors."
"Not bad."
Tsunade nodded, satisfied with Minato's solid theoretical foundation. "Just as you said, chakra is hereditary. That's why the Senju clan's chakra natures are mostly Water and Earth."
"As for Wood Style... how much do you know about Bloodline Limits?"
"Not much. I just know it was the First Hokage's ability."
Minato shook his head. Chakra characteristics were basic knowledge for beginners, recorded in the scrolls his father left. But Bloodline Limits weren't mentioned, as they weren't something he needed to know back then.
"Listen well. Chakra is energy created by mixing physical energy and spiritual energy in a one-to-one ratio. Ninjutsu is the effect produced when chakra undergoes different forms of change through hand signs."
Tsunade held up two fingers. "Generally speaking, chakra changes can be divided into two types: Shape Transformation and Nature Transformation."
"Training in Shape Transformation improves your control over chakra. Training in Nature Transformation increases the power of elemental Jutsus. A Bloodline Limit is the power formed by fusing two Nature Transformations."
"For example, your Wood Style is a mixture of Water Style and Earth Style Nature Transformations."
Minato raised his hand. "So, Sensei Tsunade, does this mean I inherently master two Nature Transformations?"
"Yes, but not entirely."
Tsunade shook her head and smiled. "The real difficulty of a Bloodline Limit lies in using two Nature Transformations simultaneously and fusing them. For example, performing Water Style Nature Transformation with your left hand and Earth Style with your right."
"For someone born with a Bloodline Limit, this ability is like a biological instinct. You are born with a foundation for certain Nature Transformations and the ability to fuse them. But that doesn't mean you don't need to train in Nature Transformation."
"In fact, because your Bloodline Limit is a mix of two natures, you actually have one more Nature Transformation to train than other people."
Saying this, perhaps worried she might discourage him, Tsunade added, "Of course, the power of a Bloodline Limit is definitely much stronger than a single-element Jutsu. And even without a Bloodline Limit, to become a qualified Jonin, you need to master at least two Nature Transformations anyway."
"If someone with a Bloodline Limit naturally has the ability to release two Nature Transformations simultaneously..."
Minato thought for a moment. "Then could I use that to synthesize even more Bloodline Limits?"
"Theoretically, yes. But let's wait until you master one Nature Transformation first."
Tsunade laughed and patted the scrolls next to her.
"Among these scrolls, the white ones record training methods for Shape and Nature Transformation. Yellow is Earth Style, blue is Water Style, and green is Wood Style. These are all things you'll need to learn. I plan to start teaching you from the very basics."
Minato tilted his head. "Training for Shape and Nature Transformation?"
"It's Chakra Control!"
Tsunade rolled her eyes. "In terms of training order, Shape Transformation usually comes before Nature Transformation. But that's usually something Chunin-level ninjas deal with. For you right now..."
Tsunade paused. She leaped up, flipped, and stood upside down on the ceiling, a smug smile on her face.
"This is your next training goal~ Don't think just because you learned the Shadow Clone Jutsu, you're all set."
Minato looked up at her. "Actually, I already know how to walk on water."
Hearing this, Tsunade's smile froze. "You know it?"
"Yeah."
Minato nodded. "It was in the scrolls my father left. It wasn't very hard."
Tsunade silently jumped down from the ceiling. "Well... chakra control isn't too advanced, I guess. How long did it take you to master it?"
"Ten minutes."
"Pfft..."
Tsunade laughed in exasperation. "Geniuses are so unreasonable..."
It took her about ten minutes back in the day, too. But she had already graduated from the Academy by then. Minato hadn't even enrolled yet...
"In that case, let's start with Shape Transformation... Shape Transformation is an extension of chakra control. There isn't a very specific way to train it."
Tsunade sighed, her tone sounding a bit bored. "Internally, you can improve proficiency by constantly refining chakra and circulating it through your body. Externally, you can coat your body in chakra and shape it into different forms to improve control."
Minato watched Tsunade silently. He felt like she was starting to slack off.
And he wasn't wrong. Tsunade was slacking off...
Because she suddenly realized that apart from combat experience, she had nothing left to teach him!
Tree climbing and water walking? Minato already knew them.
Nature Transformation, which only Jonin mastered? Because of his Bloodline Limit, he was born with the foundation for two... or maybe even more.
As for Shape Transformation? Given how fast he learned water walking, he'd probably reach a high level in no time.
But that was basically the configuration of a Jonin in the village!
Some Jonin didn't even master a second Nature Transformation...
What terrified Tsunade the most was that once Minato finished this training, he would surpass her in raw specs!
If she were 30 and Minato were 15, she could accept it. In fact, she'd be happy for her genius student.
But she was 19, and Minato was 5. That... that actually broke her spirit a little...
