Even though the Emperor had issued an order, it was hard to hunt down everyone who had a connection with the Raizel family in a single day, considering how vast the Empire's main planet was.
All in all, it was just for show. Those who were present within the big cities that were close to the coliseum were the ones who were hunted first. And from there, all of the airfields throughout the whole planet were closed down, preventing anyone from fleeing.
Nonetheless, it wasn't like the Imperial soldiers could immediately pinpoint the location of the people that tried to hunt. As such, the higher-ups created some kind of wall made of soldiers around each city to prevent anyone from leaving and entering the city. After that, they would proceed in searching every corner of each city thoroughly before moving to the other place outside the city.
