Maxed Out for the Netherworld War

The Netherworld came down over the world once already. Everyone alive woke a profession according to their talent, and moving up the ranks of a profession took nether credit in quantities most people never came near. Colin Sanders died there. He comes back to a point before any of it, with the game interface from that life still on him. Nether credit is bought with paper money, so he spends and keeps spending until the balance in his Netherworld account has no ceiling on it. Then the descent happens on schedule. He starts out as a blacksmith at D rank. With the money behind him he forges three divine artifacts and specializes the rank into divine blacksmith, then changes profession again from there.
