Kabuto Yakushi gave Obito a somewhat pitying look. This man was going to get thoroughly screwed over; his every move had been calculated.
"Yes! Do you have any tissue from the deceased? As long as there's a piece of bone, I could bring back even the Sage of Six Paths.
"Of course, this isn't true resurrection. It's only lodging a soul in someone else's body."
"Will his strength be affected?"
"There's a way to keep it under control."
"Wait for me!"
Obito vanished. Five minutes later, a severed arm appeared before Kabuto Yakushi.
"Is this enough? Will he come back as he was when he died, or when he was young?"
"Enough! Do you want to revive him now?"
"Right now!"
Kabuto Yakushi nodded calmly. "We're still missing a sacrifice. Go catch someone. A White Zetsu will do, too."
"Then a White Zetsu it is!"
To learn the Eight-Tails' location as soon as possible, Obito directly controlled a White Zetsu and brought him out as a sacrifice.

Obito Uchiha was horrified. "Quick! Get him under control! Don't let him wake up yet."
"Don't worry. The final step isn't finished yet!"
As he spoke, Kabuto Yakushi took out a kunai bearing a Cursed Seal and drove it into the back of Madara Uchiha's head.
Madara Uchiha slowly opened his eyes. As his consciousness returned, he murmured to himself:
"This day has finally come.
