Louis's face turned red, but he managed not to blurt out "You will become a corrupt official who is eventually executed by the King".
The young master in front of him clearly wasn't that corrupt official from the future yet.
If he had said it, it would have been like revealing the young master's future destiny in advance.
"Because you're not cut out to be an official."
"Too late, I'm already an official, the peace officer of the Eternity capital of the Ande Kingdom, in charge of the capital's security."
You're new to the Eternity capital, you don't speak the language, and if you want to make a living... you still need to get a temporary ID card. Even with a temporary ID card, you won't be able to find suitable work right away. Considering you keep saying "young master"...
I'm giving you a chance, to be my subordinates, to maintain the peace in the Eternity capital and to apprehend those who disturb the peace and commit crimes.
