The Culmination of Two Million Years (200万年の結晶 Ni-hyaku-man-nen no Kesshō) is the fifteenth episode of the Dr. Stone anime.
Summary[]
With Magma defeated, it's down to Senku and Ginro to take the throne. Although both are on the same team, one is driven by personal greed and opportunism. The fight is on!
Plot Details[]
Ginro tells Ruri that Senku and he will forfeit their fight and Chrome will be the winner, just as she would prefer. However, being in that position, Ruri states she would marry the winner, no matter who he is. Ginro misunderstands it, thinking she had no preference. As the second semifinal between him and Senku starts, Ginro takes Senku seriously, as he had imagined himself as the village chief, and quickly turns the crowd against him with his fantasies. Chrome throws Suika's mask at Senku. Seeing that, Ginro decides to act quickly before he uses some crazy sorcery; however, Senku uses the mask as leverage and smacks Ginro in the balls, knocking him out and taking the victory.
Next are the finals, and Senku intends to lose on purpose so that Chrome can marry Ruri. However, Chrome is unconscious and unable to fight. Everyone is shocked, but having no choice, they announce Senku as the winner and the man who will marry Ruri and become the village chief. Senku agrees to do it and asks them to bring the wine. Ruri coughs up blood, and Senku realizes they are almost out of time. He wants to make antibiotics, but the villagers explain that he first needs to celebrate all night. Hearing that, Senku then announces his divorce, takes the alcohol with him, and heads to make the medicine.
Returning to their base, Senku leaves Kaseki and Gen Asagiri watch over a spinning bamboo at a waterfall. At their base, as a first step, Senku takes burned coal and washes it with hydrochloric acid, then adds ethyl acetate made from alcohol and vinegar to get anillin. They proceed to do 25 more steps. In the morning, Gen is eager to see what is inside the bamboo and is surprised by its carbonated water. Happy that Senku may indeed be making cola, he returns to their base to find Senku and the rest lying on the ground, as the experiment seemingly went wrong. Senku explains how he mixed some things, and it caused a small explosion. Taking the carbonated water, Senku mixes it with sodium hydroxide and creates baking soda. After mixing the last ingredients, after six months of arduous work, Senku created the sulfa drug.
The group heads into the village, but as Gen isn't allowed, he must stay out. Senku tells him to stay and wait for them in the lab. Gen is disappointed; he can't see Ruri getting better, but upon entering the lab, he sees a bottle of Senku's cola on the table and happily drinks it. Senku's group meets with Ruri, and he gives her the medicine. As he examines her, he sees a dead mouse and takes it back to his lab. Making an autopsy, Senku confirms the mouse also has a bacterial infection and explains that depending on the bacteria, his cure may not work. Moments later, Suika calls them as Ruri gets worse. Seeing Ruri's condition getting worse, Senku admits it may be due to his medicine and explains that the bacteria is getting serious and is making allies by spreading its toxic genes into the harmless bacteria around it. That is the pneumococcus bacteria's special move, making him realize Ruri has pneumonia, but his medicine destroys the pneumococcus bacteria. If they keep giving her the medicine, she will recover. With everyone's support, Kokuyo and the rest accept. Soon, Ruri makes a complete recovery. Kokuyo announces Senku as the village chief of Ishigami Village. Hearing Ishigami's name surprises Senku, and Ruri tells him she is aware his name is Senku Ishigami.
