"The elixir, as you may know, contains the physical manifestation of laws. I can sell some, but I need other items which contain laws in a similar fashion," said Lex as he began to explain his demands.

Inferior items are also acceptable, but then the quantity needs to be increased. How much elixir I give you depends on the kinds of resources you provide. After all, I've approached a few other circles as well, and if their offer is better than yours, then they will get more of the liquid."

Powell did not show any surprise, relief or competition on his face upon hearing Lex's demands. He remained extremely professional, and immediately delved into relevant matters.
