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.
I'm glad I fell forward.
.يسرني أني سقطت للأمام
d’être tombé vers l’avant.
Sono riuscito a cadere in avanti.
Que bom que caí para a frente.
что я упал лицом вниз.
