Noir is the 3rd son of a poor noble and his job position is taken away by a more powerful noble. He also sadly lacks enough skills to attend the Hero Academy. He tries to find a way to be able to use his skill [Great Sage] better and stumbles across a hidden dungeon.
It's better than bringing a golden slime, 
which doesn't exist on this continent.
هذا أفضل من إحضار هُلام ذهبيّ والذي
لا يتواجد في هذه القارّة
Es sollte zumindest normaler sein als ein goldener
Schleim, den es auf diesem Kontinent nicht gibt.
Es mejor que mostrar un slime dorado
que no existe en este continente.
C’est plus naturel que le slime doré
introuvable sur ce continent.
Ma è sicuramente meglio di uno slime dorato,
Deve ser melhor do que um slime dourado,
que não existe neste continente.
Лучше, чем золотая слизь, 
которой на этом континенте нет.
