Unfortunately, this was nothing more than impotent rage.
Obito had no way to retaliate against Shiraishi Yoshijo at all.
Peach Country's Anbu was filled with experts. Forget going alone—even if he dragged every Akatsuki member along, it still would not be enough.
After thinking it over, Obito suddenly asked, "Zetsu, do you have any way to deal with Shiraishi Yoshijo?"
"Huh? Obito, give up. You can't do it. Only Madara can deal with that guy."
"What about Nagato?"
"Even with Madara's Rinnegan, Nagato still can't do it. You have no idea how strong Shiraishi Yoshijo is. Aside from that battle with Madara, he has never gone all out against anyone else."
After thinking carefully, Obito realized that did seem to be the case. Even when that bastard made a move, he only used one or two techniques. If his subordinates could handle something, he would never act personally. He was extremely cautious.
It seemed that only by becoming the Ten-Tails' Jinchuriki could he deal with that bastard.
"Come with me to see Nagato!"
"Obito, Nagato really isn't Shiraishi Yoshijo's match."
"It's not about that. There's something else to discuss."
The tallest iron tower in Amegakure.
Konan pushed open the doors and led the two men before Nagato.
The gaunt and haggard Nagato slowly opened his eyes, staring at them expressionlessly. "What brings you here this time?"
Obito said, "I have good news. I've reached a deal with the Emperor of Peach Country. As long as we pay, we can buy large-scale destructive weapons. I can also hire top Medical Ninjutsu specialists from Peach Country to treat your injuries."
Konan said, "Treat his injuries? Even Mr. Sangzhi couldn't do anything..."
Obito said, "Sangzhi is just a quack. His Medical Ninjutsu is far from good enough."
"You called me a quack?
