Dr. Stone Wiki

Fateful 20 Seconds ( (うん) (めい) の2 0 (びょう) Unmei no Nijū-byō) is the seventy-fourth chapter of the Dr. Stone manga.


The cell phone conversation with Ukyo continues, and he says that he may be persuaded the join the Kingdom of Science on one condition: that no one dies. Senku agrees easily, having already planned to have no bloodshed in this war. Ukyo also says that their conversation together confirmed that Hyoga was lying about who killed the member's of his group.

At Senku's grave, Hyoga notices that the footprints are too neat, almost as if the area had been swept and a false set were made. Tsukasa soon joins him, so that he can pay respects to Yo who died. In reality Yo simply escaped so that he wouldn't get in trouble.

Paper is being made in the Kingdom's hidden base camp, and the tank is completed. Gen asks how they can even shoot when they don't have gunpowder, but Senku explains that they're using pressure created by the gases from water electrolysis. They'll only have one shot though. The fighters gather while Taiju and Yuzuriha appear, the friend group's first proper reunion in a year.

Back at the grave, Tsukasa notices something amiss with the ground, and rips the cell phone receiver out. He's discovered the cell phone! At the same moment, the 20-second attack on the Cave of Miracles begins.
