All that’s needed to make antibiotics is alcohol. The best way to get some is to win the Grand Bout, which the Senku and his kingdom will also need to do in order to keep Magma away from Ruri and give her the drug.
It turned out the exact 
opposite of what I prayed for!
!حدث عكس ما كنت أدعو له
Das Gegenteil meiner Gebete ist eingetreten!
¡Fue justo lo contrario a lo que pedía!
¡Es justo lo contrario de lo que pedía!
C’est à l’opposé
des prières de Suika !
Tutte le mie preghiere hanno avuto l'effetto opposto!
Deu exatamente o contrário do
que nós rezamos para acontecer!
Я молилась, а всё вышло наоборот!
