Shinobi World No. 1.
Autumn, Konoha Year 43.
The Imperial Pharmacy, Imperial Palace.
The Foundation Establishment Spirit Liquid in the copper pot had finished brewing. The pale golden liquid had been divided among dozens of jade bottles, neatly arranged on a shelf. Kushina sat nearby, holding a cup of warm flower tea. As her gaze fell on those jade bottles, an indescribable mix of emotions welled up inside her.
Toyotomi Yinglang stood before the workbench, a long scroll spread out before him. The scroll was densely covered in writing-not ordinary text, but medicinal formulas.

"There's more."
He turned to the scroll's second page.
