The prices of magic metals are very expensive, and the individual needs of general wizards are not very high.
Apart from groups like Mechanical Wizards and Alchemists, most wizards buy only small amounts that are sufficient for their use.
But Duke is different; he needs as much magic metal as possible, accepting all that comes.
Even with his current income, he cannot afford to buy magic metals in large quantities.
Strictly speaking, the body of the summoned demon god is not entirely composed of magic metals, but is ordinary yellow sand mixed with magic metals.
If the 300-plus meters body of the demon god were to be entirely made up of magic metals, tens of thousands of tons would not be enough.
In Duke's yellow sand crystals, only two to three thousand tons of yellow sand have absorbed magic metals, while the rest is ordinary yellow sand, far from enough to fully construct the body of the demon god.
