If You're a Magical Prodigy, Then What Am I?

Yuri Frederick, reincarnated as a mage in another world, suddenly discovered that he had received a beginner's gift pack the moment he arrived. But the gift pack was almost absurdly generous: Wordless casting... and a bottomless reserve of mana. The perfect package for a prodigy! He also gained the right to freely enter and leave the magical utopia of "Goldgrave." In "Goldgrave," magical knowledge pours into your head every moment, and ownerless mana fills the air in such abundance that it can even take physical form... Even a wolf hair plucked from the roadside is a rare, high-grade magical material. In the real world, it could sell for as much as he earned from a month of part-time work at the magic academy! At the freshmen's entrance ceremony, noble students in the audience mocked him. Yuri Frederick simply kept a calm expression and said, "I'm a magical prodigy... What are you?"
