The entire process of recreating it went off without a hitch, once again confirming the loophole in Izanagi: it could peer into the branches of fate.

Shinji didn't even have a pair of Rinnegan yet. He hadn't even touched the threshold of Six Paths level, so he was nowhere near qualified to bear the weight of fate.
Brushing those thoughts aside, Shinji immediately began basic tests on the prepared medicine.
He was already familiar with the process. With the help of several precision instruments in the secret laboratory, it didn't take long for him to confirm that the new Aging Agent had been successfully formulated.
