After fighting with Ice for more than 2 or 3 hours in the bed, which ended with her loss of course, Eric could finally enter his System Shop to purchase his necessities.
Since his Legacy System was still in hibernation then he could only purchase from the things that were already listed on the System Shop window.
While most of those things weren't particularly useful to him at the moment, there were a few things that were, like Alchemic knowledge level 2.
No matter where, no matter when the richest people alive would always be the drug dealers, doctors, and people in the entertainment.
If one looked at things in really crude terms then Alchemists were just high-level drug dealers. That could be seen just from the deals, and money he got from the big families for the formulae of the potions.
People would normally spend more than a few lives to earn that money, while he was able to earn it in just a short moment.
