National Security Bureau, an enclosed internal location.
The area is roughly the size of a soccer field.
At this moment, hundreds of people are densely standing on the field, and they are none others but the soldiers and police officers elected from local military districts and municipal police departments across the country.
"Judging by your uniforms, you must be from the military district?"
"Are you from the municipal bureau?"
"Both military and police personnel, why has the National Security Bureau gathered so many people here?"
"What we don't know is why we are here, but what we do know is that it must be a big operation."
"..."
This is their first meeting.
Seeing so many people around them, from both the police and military, they become increasingly confused and curious about why they have been called here.
Just at that moment.
Suddenly!
The door of the closed venue slowly opens.
Immediately!
The scene falls silent.
