Madara's wild laughter gradually faded into the night sky.
But his wildly surging chakra became ever more distinct.
Chiya could clearly sense Madara's chakra seeping steadily into Obito through the cursed seal inside him.
The cursed seal was like a bridge connecting Madara's soul to Obito's.
It was also Madara's final safeguard for his own resurrection.
Chiya lowered his eyes to Obito, who lay collapsed on the ground.
Obito stared down at the black cursed seal spreading across his chest, his face filled with terror and disbelief.
His body trembled slightly, beyond his control.
Wherever the cursed seal spread, an unfamiliar power forcibly took control of his muscles and chakra pathways.
His own will was being stripped away bit by bit.
"What the hell is going on..."
Obito's voice shook uncontrollably as he looked up at Chiya, panic filling his eyes.
"What exactly is this cursed seal Madara left for?"
"What is it for?"
Chiya scoffed, his tone icy.
"You've been Madara's pawn for so many years, and you still haven't figured it out?
This cursed seal is his insurance for resurrection.
He's going to use it to control your body and perform Rinne Rebirth.
He'll trade your life for his true resurrection."
Obito's pupils instantly contracted.
All color drained from his face.
Rinne Rebirth.
Of course he knew that technique.
It was the ultimate advanced form of Impure World Reincarnation, capable of fully restoring its reanimated dead to living bodies of flesh and blood.
And once the technique was complete, its caster would die.
Madara had transplanted the Rinnegan into him all those years ago for this very day.
So that he would use his own life to truly resurrect Madara.
He had always thought it was an agreement between him and Madara.
Something he would do for Madara
