Chen Jiu didn't think Feng Jun's asking price was excessive at all. The effects and influence of the Life Potion are indeed significant, but it depends on who's asking for the cure—when using the Life Potion stops being effective, and someone else can help you extend your lifespan, shouldn't you be a bit more sincere?
As for the claim that the widespread use of the Life Potion would destabilize the Federation's rule, he acknowledged that notion, but what if the individuals don't belong to the Federation's power?
Chen Jiu had no doubt that Feng Jun was not aligned with the Federation's power because the Federation simply couldn't do what he did.
Moreover, Feng Jun never settled accounts using Federation currency; he always used energy stones. Initially, he thought the other party might be with the Rebel Army, but clearly, there was no way that anyone in the Rebel Army could live to be five hundred years old.
