Inventions of God and Devils (神と悪魔の発明品 Kami to Akuma no Hatsumei-hin) is the 124th chapter of the Dr. Stone manga.


Now allied with Kingdom of Science, Mozu strikes at the Petrification Kingdom, attacking and defeating Oarashi, who then goes on to spread news of the invader.

Fearing retaliation from Mozu should he actually obtain the Petrification Weapon, Senku devises a invention to defeat him: a handgun. Ukyo and Ryusui discuss the ethics of using guns before agreeing to use it non-lethally.

The group then awakens their only member with firearms experience: Yo. At first, Yo is tempted by its power, but Amaryllis seduces and pacifies him. He then demonstrates his expertise, shooting a venomous snake from far away. However, unknown to the group, Yo missed his target, and hitting the snake was an accident.

Chapter Notes

  • Firearm acquired!! Senku creates a firearm using parts from the mobile lab, gunpowder, nitric acid, mercury, and alcohol.
