Dr. Stone Wiki

Ultimate Resource ( () (げん) (おう) (さま) Shigen no Ōsama) is the eighty-fifth chapter of the Dr. Stone manga.


Minami cries over the loss of Tsukasa, but Senku has a job for her reporter skills and she gets back up. He tells her that he needs a navigator who can captain a ship to get them to the other side of the world.

With the power team in tow, Minami directs them to the location of Nanami Academy, a maritime school from before the petrification. She begins to mention someone who may perfectly fit the bill, but covers it up. The power team begin digging up every statue in the area, hoping to locate the perfect person.

A while later, she notices a particular statue and reacts badly, making everyone else take note. They ask her who the person is, and she responds that he's part of the Nanami Conglomerate, one of the old-money families of the area, and that he's also an expert sailor. Everyone is excited about the man's expertise, but Minami insists that his personality isn't great. In the background, Senku revives him.

Ryusui appears and seems to have several astute observations on his current situation, impressing them all. Once clothed, Senku shows him around their shipyard with Ryusui passing all of Senku's tests. They almost get caught in a storm, but Ryusui tells them all to head for shelter before it happens. Ryusui then says that Senku must be after oil, and says that everything in the world will be his.
