Profitable missunderstanding

To be honest, I didn't expect this pill to go for so much! I know how important it is to get an external source of energy to cultivate when the free energy of the world is spread so thin, but who could've thought that this measly pill that couldn't even fill a ten percent of my current mana pool would be almost as valuable as the sword that I offered before! 

Thinking about, if my estimates will turn out to be on point, an almost identical sword that will be auctioned right before the climax of the auction will be sold for even less than this pill!
