If we let the explosives detonate in the C21 District, do you really think the Special Operations Department can stay out of it?
Don't forget, although they are two departments, they both belong to the larger Judicial Bureau.
At that time, if other departments use this to impeach the entire Judicial Bureau, it might weaken the Bureau's current power. When the leadership sits as Director, wouldn't it indirectly weaken the leader's power?
Moreover, there are tens of thousands of people up there! Can you just let them die?
With various chain reactions, it's possible that the promotion of the current Director, Yan Chong, that old guy, could get delayed again and again, making it extremely difficult for the leader to get promoted to Director.
This is truly a case of pulling one thread and moving the whole body.
"So I intend to flood it, to provoke the entire security team and the full strength of the Apocalypse Society while also preserving the C21 District."
