Dr. Stone › Saison 1 Dr. Stone : Stone World

Chapter 8 — Episode 8

First, the episode opens with the village elders discussing the outsiders, suspecting they are either exiled criminals or people awakened from stone statues. It is quickly revealed that Kohaku brought them to the village, angering her father Kokuyou, the village chief. The tension is interrupted when Ruri, Kohaku's ill sister, suffers a severe coughing fit, reinforcing the urgency of finding a cure. Then, Senku explains to Chrome and Kohaku that the goal is to create antibiotics — either penicillin via a biological route or sulfa drugs via the stone route. Since the penicillin route relies on luck in finding the right mold, Senku decides the group will follow the stone route, which is guaranteed but extremely labor-intensive. He lays out a full scientific roadmap, starting with smelting iron from sand iron collected in the river, which requires sustaining temperatures of 1500°C by continuously pumping air into the furnace for dozens of hours — an exhausting task that pushes Chrome, Kohaku, and Suika to their limits. Later, during a break, Senku notices Suika playing with a cat's tail plant and realizes it can be used to make noodles. Using foxtail grass flour, wild bird eggs, and potassium carbonate from ash, Senku prepares primitive ramen, explaining it was discovered by a Mongolian in the 4th century. Chrome and the others are amazed by the taste, and at the end, the smell of the ramen drifts through the village, attracting curious villagers. Senku declares his plan to win over the entire village using the power of scientific cooking.
