Mikami Satoru, a businessman, is stabbed by a criminal on the street and killed. When he regains consciousness in the darkness, he finds that he's been reincarnated as a slime! With nothing better to do, he spends his time devouring all the rare herbs and precious ores he comes across. As he does, he encounters the Storm Dragon Veldora, who was sealed in this cave 300 years ago by a hero's "Unlimited Imprisonment" skill. He's frightened at first, but as they talk, he becomes friends with the long-isolated Veldora.
I could've even made it 
to the rank of great sage.
وكان بمقدوري حتّى الوصول لمرتبة
حكيم عظيم
Das Zeug zum großen Weisen
hätte ich auch.
Tal vez hubiera llegado a gran sabio.
Tal vez ya era incluso gran sabio.
Voire un grand sage.
Forse sarei potuto diventare un Grande saggio.
Talvez chegasse a ser um grande sábio.
Мог бы даже стать великим мудрецом.
