Tobirama regretted that he had pushed Madara too hard, causing Madara to completely lose hope in Konoha, and his subsequent battle with Hashirama led to Hashirama's early demise. Tobirama had always felt guilty about this matter.
To be honest, Madara was somewhat incapacitated for some unknown reason back then, and he was also worried that Tobirama would use the Flying Thunder God Technique to escape, so he controlled the Gold and Silver brothers to deal with him. This way, everything seemed to be clearly explained.
Now that he knew Madara was still alive, Tobirama naturally wanted to eliminate him. If possible, he wouldn't mind joining forces to fight Madara.
However, Kazuki's words made Tobirama even more concerned. If the fact that he and his elder brother were Edo Tensei'd by Danzo was all part of Madara's plan, then...
That damned Danzo, he has completely disgraced him.
Tobirama sensed Danzo's Chakra for a long time before asking, somewhat uncertainly, "Danzo isn't under the control of a genjutsu. I'm quite confident about that."
"Danzo isn't controlled by genjutsu. To deal with Danzo, there's no need to control him with genjutsu. Just a few small maneuvers are enough. He is currently using the First Hokage's cells to nurture a white creature that can disguise itself as any ninja, and ordinary ninjas simply cannot find them. Only Nine-Tails's ability to perceive good and evil can do it. Others, even the Uzumaki clan's sensory ability, cannot." Kazuki explained to Tobirama in a shocking manner.
As expected, Tobirama's heart tightened.
Such creatures exist?
Could Madara be capable of this?
In Tobirama's mind, Madara was more like a brute.
Tobirama was very familiar with the Uzumaki clan's sensory abilities. His own sensory ability was very great, and he had always been proud of it, but he didn't think his sensory ability was superior to Mito's.
If Mito couldn't sense that disguise without the aid of Nine-Tails's Chakra, then he probably couldn't sense it either. As for Danzo, it would be even more impossible for him to sense it.
'Stupid Danzo, you've completely disgraced me.'
Although Kazuki was only guessing, Tobirama believed it for the most part.
The most crucial point was that the vessels for him and Hashirama were very likely those white creatures. Otherwise, his and Hashirama's strength wouldn't be so close to during their lifetime, and they wouldn't be unable to resist.
It wasn't that Tobirama looked down on Danzo, but Danzo simply couldn't achieve this step.
"So this is the main reason my sister-in-law came?"
Tobirama thought of many things at once, and his gaze towards Kazuki showed a hint of approval. As expected of the Uchiha most similar to him, to have thought of so much in such a short time.
"The main reason is to let Grandma Mito see the First Hokage." Kazuki looked at Mito and Hashirama, who were still fighting nearby.
"If needed, I can also call Nawaki and Tsunade to give you a chance to meet."
"Tsunade and Nawaki?"
Tobirama hesitated for a moment before shaking his head slightly and saying, "Let's not. My elder brother and I are already dead. If it's about fighting Madara, we are duty-bound, but meeting family, let's not. We will leave eventually, and it will only bring them sadness."
Tobirama had held Nawaki when he was a child, and as for Tsunade, she was personally raised by him. To say he didn't care would be a lie.
But just as Tobirama said, it's better to remember than to meet. Tsunade and their situation was different from Mito's. His sister-in-law was nearing the end of her life.
Soon, Tobirama composed himself and began teaching Kazuki again. In him, Tobirama saw a reflection of himself, as well as Madara and his elder brother. No wonder his sister-in-law and the others were so satisfied with Kazuki.
But what about Madara?
That guy shouldn't even exist, he must tell Kazuki more information about Madara.
Tobirama was giving Kazuki a teaching session, not because he was stronger than Kazuki.
Rather, his combat experience far exceeded Kazuki's, and this combat experience was the most valuable asset. Tobirama needed to impart his combat experience to Kazuki in the shortest possible time.
At the same time, he also needed to research how to deal with Madara.
On the other side, the battle between Hashirama and Mito had entered a heated stage.
Mito in Sage Mode was very powerful, subtly suppressing Hashirama, who was not at his peak and could not enter Sage Mode.
"Mito, hurry up, hit him, throw a Tailed Beast Ball at him. I have plenty of Chakra."
Kurama howled inside Mito, its nine giant tails wagging constantly behind it. It vaguely gave off a husky vibe.
Kurama had never expected that it would have the chance to see Hashirama again in this life, and Mito was even going to use it's power to deal with Hashirama. Kurama, whose relationship with Mito had already somewhat softened, naturally wouldn't miss such an opportunity.
Kurama loved watching such a plot. The more fiercely the couple fought, the better. It would be best if they smashed each other's heads.
Not only did Kurama cooperate, but it even actively helped Mito create Senjutsu Chakra, just in case Mito's strength wasn't enough. Kurama would give whatever Mito wanted, as long as she could defeat Hashirama.
To this day, Kurama still remembered how Hashirama kept saying that it was too strong, then grabbed it's throat with one hand, and then punched it repeatedly.
Even though it was controlled by Madara at that time, Kurama still remembered that scene vividly. That was also the first time Kurama faced a life-threatening crisis since its birth.
