Obviously, when fifty thousand elites enter the Ancient City with a huge amount of wealth, the turbulence and reforms they bring will be an inevitable important topic in the near future.

An excellent chef can lead the rise of a bakery or even a chain store, creating employment for dozens, hundreds, or even thousands of people.
For those who can score a passing mark, each one is a strongman among hundreds or even thousands of others. In their field of expertise, perhaps the term "excellent" is no longer enough to describe them. They just need to adapt to the local environment and naturally be able to achieve something.
