The Gunpowder Adventure (火薬冒険 Kayaku Bōken) is the seventh chapter of the manga Dr. Stone.

Summary

To enforce the plan to create gunpowder, they make their way to Hakone. Senku complains about the lack of accurate coordinates of the sextant: "Are we around Kamakura?" At this question, Yuzuriha runs and encounters a monumental outdoor bronze statue, The Great Buddha of Kamakura. Since the statue is made of bronze, it lacked the chemical reaction to break apart and the reason for the lack of greenery is that the copper ions spread out which are poisonous to most forms of vegetation.

Yuzuriha notes that the cherry blossoms seem different and Senku explains that they failed to self-pollinate and suddenly went extinct.

Taiju notes that Yuzuriha's toe is still petrified. For this they use their own created remedy.

Meanwhile, Tsukasa has come to grips with their plan.

Trivia

  • Through the bronze from the statue Senku wants to create a mirror for the sextant's accuracy.
