With the Giant Ugly Fish and the Serene Empress around, they naturally wouldn't let the Cloud Emperor Cat advance now. Instead, they let her compress the Fantastic Beast energy. When it was compressed to the limit, she would naturally advance to the intermediate level.
Only then could her potential value be maximized.
However, that Skeleton Servant was already at the intermediate level. Although its aura was comparable to that of a Skeleton Dragon, its Fantastic Beast energy was much inferior.
Therefore, the Serene Empress could tell at a glance that this Skeleton Servant's potential value was not high.
On the other hand, after the Beast Tamer obtained a Skeleton Dragon, he signed a contract with a Skeleton Servant.
Although Skeleton Servants were also relatively rare, with the conditions of the Beast Tamer, he deserved better.
Therefore, he must be short of money.
