Kohaku has located the treasure left behind by Byakuya and the others, but it's encased in concrete. Senku has to devise a plan to quietly get at the contents inside, so as to not alert the guards.
It's going to go kaboom when he mixes it!
!سينفجر عندما يخلطهما
Wenn er es vermischt,
gibt’s ’ne Riesenexplosion!
¡Explotará cuando lo mezcles!
¡Explotará cuando lo mezcles!
Si tu le fais, ça va exploser !
Se li mescola assieme,
 esploderanno facendo "boom"!
Vai explodir quando ele misturar.
Он их смешает — и тогда как рванёт!
