Tsunade has a considerable amount of Chakra, and in the current Konoha, her Chakra reserves are definitely among the highest.

Although the 'Book of Ninja' states that Tsunade's Chakra is only 8, that refers to Tsunade in her middle age, when she needed to expend a large amount of Chakra to maintain her appearance.

Putting those factors aside, Tsunade's Chakra is absolutely not small. She, who hasn't fully matured yet, already has Chakra reserves not much less than Hiruzen.

It seems understandable that she would surpass Hiruzen in the future.

Kazuki's current Chakra reserves have reached three times that of Tsunade. At just ten years old, he possesses over ten units of Chakra. It can be said that currently, among the ninjas in Konoha with more Chakra than Kazuki, only Mito remains.

And Mito also has to expend a large amount of Chakra to suppress the Nine-Tails...

When Mito realized this, she didn't find it strange. After all, Madara's Chakra reserves were considerable back then, otherwise he wouldn't have been able to fight Hashirama.

Now, Kazuki displaying more Chakra than Madara at the same age also seems understandable.

"Nawaki, you still need to train more. If you keep this up, let alone fighting Kazuki, you probably won't even be able to defeat that little blondie, Minato." Kushina said, gloating, as she looked at the exhausted Nawaki.

"Minato?"

Hearing Kushina mention Minato, Nawaki's expression stiffened.

Minato is Jiraiya's disciple. Now that Jiraiya is at the front line, Minato often comes to train with them.

With guidance from Mito and Kazuki, coupled with Minato's own efforts and talent, Minato has been growing rapidly.

His strength has reached the stage where he can graduate early, but Minato didn't intend to graduate.

Jiraiya is at the front line, and if he graduates, there will be no one to lead him on missions.

Why not use this time to diligently get stronger?

"Hmph, I admit he's excellent, but to compare with me, he's still far off."

Although Nawaki also admitted Minato's genius, he still wouldn't admit that he would be caught up by Minato. He was several years older than Minato, and he wasn't bad either.

As long as it wasn't a comparison with Kazuki, Nawaki stated that he feared no one.

When he usually fought against Mikoto, didn't he have wins and losses?

"But he's already not much weaker than when you graduated. And, sooner or later, I will surpass you too." Kushina said with full confidence, clenching her fists.

The current Kushina is not only practicing Sealing Jutsu, she is also training in Taijutsu and Chakra enhanced strength. Even Rasengan, Kushina can already use.

Although Nawaki can also use Rasengan, the time he spent on it was longer than Kushina, which gave Kushina something to be proud of in front of Nawaki.

"I won't lose." Nawaki said with a determined expression.

Minato can improve, so why can't he?

Losing to Kazuki is acceptable, but losing to Minato is not. If that happened, wouldn't he be the weakest among everyone around him?

"Minato is very talented. His learning ability is great, his Chakra reserves are not small, his reaction speed is excellent, and his combat thinking is top-tier. If he had spatial talent, he might even be able to learn the Flying Thunder God Technique." Kazuki said, speaking up for Minato.

It wasn't that he wanted to discourage Nawaki, but rather that the current Minato was already displaying that level of strength.

Even if he didn't say anything, Minato, who had already caught Hiruzen's eye, would sooner or later gain access to better resources.

"Flying Thunder God Technique?" Nawaki's expression stiffened upon hearing this.

He had seen Kazuki use the Flying Thunder God Technique before. If Kazuki were to use it against him, he would probably be instantly killed.

If Minato could master the Flying Thunder God Technique, he might truly be inferior to him.

Nawaki hadn't failed to get access to the Flying Thunder God Technique before, but unfortunately, he lacked the so-called spatial talent and couldn't learn it, which greatly frustrated him.

It was a Ninjutsu created by his granduncle, but why could Kazuki, an Uchiha, learn it, and Minato could also learn it, yet he couldn't?

"Did you hear that? Nawaki, you need to work harder from now on, otherwise you won't even be able to compare to Minato." Kushina teased Nawaki, gloating.

"What about you?"

Nawaki gave Kushina an exasperated look and said, "Once Minato learns the Flying Thunder God Technique, you won't be his opponent either. What's there to be proud of?"

However, to his surprise, Kushina said with a proud expression, "The Flying Thunder God Technique isn't omnipotent. Recently, grandma has been researching Sealing Jutsu specifically targeting space-time Ninjutsu. As soon as Grandma develops it, I can learn it."

"And you, without much talent in Sealing Jutsu, even if it's developed, you won't be able to learn it."

Nawaki's expression stiffened as he said, "Why is grandma researching this kind of Sealing Jutsu? Is she going to target Kazuki or something?"

"That's not it. Since the Flying Thunder God Technique exists, it's hard to guarantee that other space-time Ninjutsu won't appear. We can't underestimate the abilities of other ninja. Researching Sealing Jutsu or barriers that prohibit space-time Ninjutsu is very necessary." Kushina explained, shaking her finger.

"There is indeed a need for that." Kazuki thought of Obito in the future.

If Konoha had such Sealing Jutsu, Obito wouldn't be able to act so cocky.

As for whether such Sealing Jutsu can be developed, Kazuki was very optimistic, but the difficulty might be unusually great, perhaps even harder than learning the Flying Thunder God Technique.

"Alright." Nawaki scratched his head and sighed helplessly.

"By the way, how are my sister and them doing? There hasn't been any news from the front line for over a month."

"If you want, you can use Katsuyu to transmit information."

Kazuki glanced at Nawaki, and then added, "Hanzo's strength is very formidable, but it's also not easy to defeat the three of them."

"Moreover, he also has to consider the subsequent situation. Once Hokage-sama enters the fray, it will definitely be a disaster for the Land of Rain."

Kazuki's gaze deepened as he said, "Actually, if possible, I would really like to meet that demigod."

Kazuki hadn't fought Hanzo yet. If there was a chance, it would definitely be very interesting.

In the current Ninja World, Kazuki fears no one except Mito and Madara.

Having stayed in the village for two years, he needed to make a name for himself, otherwise some people in the Uchiha clan would start causing trouble.
