Gu Hang is waiting for the results of this meeting, which of course discusses matters related to Yasida.
In fact, this is not the first meeting on this topic.
In the previous meeting, Yasida was already stripped of the title of High Lord of the Empire. Simultaneously, an emissary group composed of Tribunal, Empire Government, and National Church members was sent to hold accountable and investigate. Accompanying personnel are elite, including Hunter Group from Tribunal, Stormtroopers selected from Star Realm Army elite, and Battle Nuns from the National Church.
The total number exceeds one hundred thousand.
This scale of force won't suffice for interstellar warfare. However, judging by their composition, it's clear they aren't meant for combat, but rather for executing special operations.
The reason such a 'small' scale operation requires one hundred thousand troops is because small scale combat aims to cover areas that might span a whole planet, or even multiple planets.
