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


Senku, Taiju and Yuzuriha on their journey to acquire gunpowder find The Great Buddha of Kamakura. The statue remains greatly intact due to the bronze chemical composition that makes it more resistant to corrosion, it also has released copper ions over time that has prevented a lot of vegetation from growing near the statue. The only damage to the statue is complete corrosion of its right cheek and right arm.

Senku mentions that the cherry blossom known as Prunus Yedoensis "Somei Yoshino" has gone extinct because they couldn't self pollinate.

Senku, Taiju and Yuzuriha make their way to Mount Hakone with Tsukasa hot on their heels, so they must hurry and acquire the final ingredient they need to make Gunpowder.
