The Lord of Hell should not allow anyone to challenge his authority, even if it's just in terms of wealth.
If it were simply counterfeit money, Asmodeus would definitely slap Amberser, who printed the fake money, to death without Aeo stopping him.
But the problem is that what Amberser printed was "inferior coin," and this stuff can really burn.
All kinds of devices widely used in Hell can use this inferior coin, and its effect isn't much worse, so you tell me, would the Hell Lords use it?
And as long as Amberser is willing to bear the cost, he could also print real money.
What's so special about normal soul currency? Isn't it just that it can be broken down into a complete soul? Amberser can create complete souls too, except that this swindler reduced the cost by keeping only extreme emotions, leaving out other functions like movement and thought.
So, the real operating mode of the Soul Bank is to play the time difference.
