Kazuki came outside. At this moment, Mikoto, Kushina, Minato, Nawaki, and Rinka were either training or sparring with each other. Seeing this, Kazuki nodded in satisfaction. These were his direct comrades in the future.

He naturally hoped that the stronger these five people were, the better.

Kazuki sat aside, opened the box, took out the Wood Release scroll, and carefully read it.

Based on the water and earth Chakra proportions for Wood Release on the scroll, a branch with two leaves appeared in Kazuki's palm in just a moment.

In that instant, Kazuki knew that he could use Wood Release. Next, he would study these Ninjutsu.

Wood Release: Deep Forest Emergence, Deep Forest Bloom, Wood Clone, Advent of a World of Flowering Trees, Wood Dragon Jutsu, Wood Golem Jutsu, Sage Art: Wood Release: True Several Thousand Hands.

All these advanced Wood Release techniques were available here. This saved Kazuki a lot of effort, as he didn't need to develop these ninjutsu himself.

Kazuki was actually quite fortunate. The Chidori series and the Rasengan series were waiting for him to develop, and now there was also the Wood Release series for him to learn.

This was a happy problem. Anyone who could learn these things would become a strong person.

"Kazuki, what are you looking at?"

Kazuki's actions quickly attracted the attention of Nawaki and the others, who all looked over.

"Hehe, it's a training scroll Grandma Mito gave me, just studying it."

Kazuki decisively hid the branch. He didn't want to expose the Wood Release matter yet.

An Uchiha being able to use Wood Release.

The Senju clan might tacitly approve Kazuki's use of Wood Release due to Mito, since the scrolls were given by Mito, what could they say?

But the Uchiha clan would definitely riot. An Uchiha using Wood Release would undoubtedly cause a huge stir. This would not only fail to make the Uchiha happy but would make them feel humiliated.

Admittedly, Madara couldn't defeat Hashirama back then, but was the Sharingan really that inferior?

The Uchiha's top genius using Wood Release instead of the Sharingan was absolutely intolerable to the arrogant Uchiha.

They could accept not being able to defeat Hashirama, but they couldn't tolerate an Uchiha giving up on the Sharingan themselves.

"Training scroll? I wonder whose it is. Seriously, even when I want these things, grandma usually won't let me see them." Nawaki muttered at the sight.

Sometimes, Nawaki strongly suspected whether he or Kazuki was Mito's grandson.

The difference in treatment was simply too great.

Oh, right, even his sister didn't receive the same treatment as Kazuki.

No matter how he looked at it, Kazuki's treatment seemed to be the best.

"Your grandfather's, it's mainly so I can continue to perfect Sage Mode with this." Kazuki put away the Wood Release scroll.

In reality, his Sage Mode was already more complete than Hashirama's. However, he hadn't integrated Sage Art into his combat system yet.

"Sage Mode?" Nawaki frowned.

He had thought about learning Sage Mode before, but Mito had refused him.

In Mito's words: "Your sister hasn't even learned Sage Mode yet. When you reach your sister's strength, then go study Sage Mode."

In reality, this was cutting off Nawaki's path to learning Sage Mode.

Although Nawaki's talent was good, he still couldn't compare to Tsunade. There was too big a age gap between them.

It would take Nawaki a long time to catch up to Tsunade. Even if Tsunade stopped making any progress now, it would be difficult for Nawaki to catch up to Tsunade without seven or eight years.

But would Tsunade really stop progressing? Impossible!

"You don't need to learn Sage Mode. The Rasengan can serve you for a long time."

Kazuki gave Nawaki an annoyed glance, then a Rasengan appeared in his hand, followed by a Big Ball Rasengan. Then, to show off, Kazuki even brought out the Ultra Big Ball Rasengan.

This scene stunned everyone, including Kushina and Minato.

As for Mikoto, she hadn't studied the Rasengan. She usually trained in Chidori, which was clearly more suitable for her than the Rasengan.

And for Rinka, Gentle Fist was enough for her to learn. Neither Chidori nor Rasengan suited her.

"Rasengan, Big Ball Rasengan, Ultra Big Ball Rasengan. Nawaki and Kushina, you both have a lot of Chakra, so you can develop the Rasengan based on that."

"As for Minato, the regular Rasengan is enough for you to use."

Kazuki put away the Ultra Big Ball Rasengan and instructed them, "Once you've learned it, consider how to integrate the Rasengan into your combat system in your battles, how to form the Rasengan faster, and how to increase its destructive power."

In reality, the same ninjutsu used by different people would have different power.

Just like the Rasengan, when used by early Naruto, it was on a different level compared to when used by Jiraiya and Minato.

Ultimately, early Naruto used the Rasengan by taking shortcuts. His Chakra control was still a bit too poor, and the Rasengan's power was a bit lacking.

Kazuki deeply understood this point.

And for a ninja like Minato, who had a decent amount of Chakra but not an excessive amount, they usually needed to fight carefully, and it was worth striving to increase the destructive power per unit of Chakra.

"Yes, I will work hard." Minato nodded repeatedly.

The Rasengan was the most difficult and most powerful ninjutsu he had learned so far.

This was a ninjutsu developed by Kazuki himself, yet Kazuki directly taught it to him. It was impossible for Minato not to be grateful.

When he asked Kazuki for ninjutsu instruction, Kazuki was generous with his teachings, holding nothing back.

Coupled with the good relationship they maintained during their school days, this made Minato increasingly acknowledge Kazuki, even feeling an impulse to follow him.

There was nothing he could do. Minato did want to become Hokage, but reality didn't allow it.

Kazuki could defeat Hanzo one-on-one, and Hanzo was a Kage-level powerhouse, while Kazuki was only ten years old.

Minato felt that he might never be able to catch up to Kazuki. Living under Kazuki's halo, it was difficult for Minato to even feel a desire to compete.

At most, he could compete for the Hokage position after Kazuki.
