Chapter 285: Nohara Rin: Who’s the Villain?
It's clear that the blood Itachi gave Obito was secretly replaced by him.
The small half-tube of blood actually belonged to Nagato!
It was also secretly collected by Itachi using a summoning creature after Nagato's original body was cut in half by the Raikage.
As for sealing Edo Tensei Rin and stabbing Orochimaru, it was all done for Obito so he could release Hidan and activate Hidan's evil god curse.
Originally, Itachi planned to capture Hidan himself and use an illusion to control him so he could cast the curse.
Unfortunately, he had searched all over Iwagakure before, but found no trace of Hidan.
There's only one possibility, the other party is hidden by Nagato or Obito.
The only thing he can do is to deceive Obito and let him control Hidan to kill people.
"The plan worked. Hidan's curse is truly magical! Unfortunately, it seems there was a small accident."
"Obito only cut off Nagato's arm, but didn't kill him!"
Orochimaru looked at Nagato in the distance and sighed with a little regret.
