Draco and Eva paid out the money to the broke bitch Water Elf, no longer even willing to mention her name in their heads lest they be infected with her poverty and lowlifeness.
When Draco opened his Inventory to take out the money, he saw plenty of zeroes behind his platinum counter. Forget 3 million, he could have paid out a billion or a trillion to this woman for this item wihtout feeling the pinch.
Then, there were his countless and almost overflowing Aether Crystals. To give you an idea of how many he had, the last time he checked them was about 2.5 to 3 years ago.
The skill allowed him to make 1 crystal every 15 minutes that was always at the top-grade. So if we were to calculate using that, it meant that in at least, 2.5 years, he had produced nearly a 100,000 top-grade Aether Crystals!
That was just him, not counting the ones from Clarent in that same period of time, from Chrona, Clarent's wife, from Hikari and even the newborn Kuro.
