"It seems you know a lot about my Edo Tensei." Tobirama was very pleased with Kazuki.
He possessed Chakra more immense than his elder brother, ocular power more terrifying than Madara, a learning ability more outstanding than his own, and Kenjutsu surpassing both his and Izuna's. Even his Flying Thunder God Technique was better than his own, truly a case of the student surpassing the master.
He specialized in Water Release, but Kazuki seemed to be more proficient in Lightning Release, a detail evident from some of his subtle movements.
However, from any perspective, Kazuki was an excellent successor. He was just too young, and his political acumen was unknown. Of course, this wasn't too much of a concern. As long as he wasn't too naive and easily deceived by those below him, it would be fine.
Otherwise, with Kazuki's terrifying absolute strength, he could suppress the entire Ninja World. Apart from the hidden Madara, Tobirama didn't believe anyone was Kazuki's match. The future Hokage would undoubtedly be Kazuki.
Knowing he couldn't stop it, Tobirama was happy to do him a favor. If Kazuki, a descendant of the Uchiha, could eliminate Madara, that would be even better.
As for why he understood Edo Tensei, it wasn't incomprehensible. After all, Kazuki's current treatment in Konoha suggested he was being groomed as the Hokage's successor.
Even if he didn't learn Ninjutsu like Edo Tensei, which were written in the Scroll of Seals, he still needed to understand them. From the black receivers Kazuki used earlier, it was clear he understood the advantages and weaknesses of Edo Tensei.
"Yes, I have studied Edo Tensei. This Ninjutsu, to be honest, is very special. When I was still weak and training with Grandma Mito, I saw your relevant notes and thought that if Konoha ever reached a desperate situation in the future, it wouldn't be impossible to ask the previous generations for help."
"Or, if we encounter heinous criminals in the future, we could summon them and force them to undertake high-intensity missions, or do things that would disgust them."
As he spoke, Kazuki looked towards Danzo in the distance.
Tobirama's face darkened. Sure enough, Kazuki had set his sights on Danzo. Tobirama also had to admit that this time, Danzo had truly made a mistake.
Researching Edo Tensei wasn't really an issue. If Danzo had done it to protect Konoha, even if he privately researched Edo Tensei and summoned them to continue fighting for Konoha, he would have gladly accepted it.
However, Danzo should never, ever have used Edo Tensei against Hiruzen.
Hiruzen was the Third Hokage, and Tobirama would absolutely not allow such rebellious behavior to occur. He had known before that Danzo's methods were wild, but he hadn't expected them to be this wild.
However, making some heinous people do certain things, it actually sounded a bit exciting.
For example, having Madara clean pastures, deal with animal waste, and sweep all the public toilets in Konoha.
Thinking about these things, Tobirama felt a little anticipation.
He didn't have the 'let bygones be bygones' mindset like Hashirama.
Since they were enemies, even if they were dead, they needed to pay the corresponding price. This was Tobirama's philosophy.
Anyway, he could not forgive Madara.
Not only all the public toilets in Konoha, but also all the streets in Konoha would need to be cleaned.
Thinking of this, Tobirama's gaze towards Kazuki was filled with gentleness. Although in some people's eyes, these actions might be extreme, dealing with enemies was completely worth it.
But looking at Kazuki, it seemed the first one to suffer would be Danzo, right?
"I've observed the surrounding Chakra, and I haven't sensed Madara. At least within a ten-kilometer radius, I haven't sensed his presence." Tobirama then spoke again.
"Hmm, for now, I also haven't sensed Madara's Chakra. Otherwise, when the First Hokage was summoned, Madara would probably have already appeared." Kazuki nodded slightly.
"However, I believe this matter is very likely related to Madara. As for Danzo, he's probably been kept in the dark all along."
Tobirama's face darkened. Danzo had really disgraced him. If only he had known, he wouldn't have taken him as a disciple.
Even a teenager like Kazuki could see it, yet Danzo, who was forty or fifty years old, couldn't. It was simply embarrassing.
When he, Tobirama, taught his disciples, he didn't just teach Ninjutsu, he also cultivated their political ideology.
And this is how you, Danzo, turned out?
I, your master, do not have a disciple who is an enemy.
"However, is sister-in-law okay with this kind of battle?" Immediately after, Tobirama looked at Mito with a hint of concern.
Mito was not young anymore. She was probably the longest-living person in the Ninja World currently.
How could Tobirama not be concerned about Mito continuing such a terrifying battle?
"There is a slight issue. If there's any danger, I'll go help immediately. Grandma Mito has my Flying Thunder God Mark on her. Oh, by the way, I've modified the Flying Thunder God Mark. I can use your Flying Thunder God Mark, but you can't use mine."
As he spoke the latter part, Kazuki had a hint of pride on his face.
As an Uchiha, being able to take such a small advantage over Tobirama was an interesting thing. After all, this was Tobirama.
"Brat!" Tobirama's face darkened.
Sure enough, no matter how good an Uchiha was, they were still very hard to like. He wondered what Monkey and his sister-in-law saw in Kazuki to nurture him so much.
Ermmm, well, upon realizing Kazuki's talent, instead of thinking about eliminating him, they should have thought about nurturing him.
For the sake of Konoha as a whole, their actions were not wrong. He would have done the same. It was just that he felt a little uncomfortable.
"Hmm?"
Suddenly, a playful look appeared on Kazuki's face.
