"If you need anything, feel free to find me."
It's not just the communication that has been lost; it's also the contact.
Just like Lao Jiu mentioned, in this sunless 'underground city', they can't go anywhere. Despite being able to walk, as soon as they approach the exit, someone intercepts them, and that damned Lao Qing occasionally appears to utter provocative words. Meanwhile, the initiator of all this has disappeared since that day and seems not to be in the 'underground city' at all.
The provocative words are meant to stir up unnecessary turmoil, and during this time, due to the innocent disappearance of the 'Black Crow' leader, many assassins have fallen into unprecedented panic. Losing the protective barrier is tantamount to falling into the abyss, followed by the pursuit from enemies and clashes with other assassin groups. No matter how powerful the organization is, absolute monopoly is impossible, and that's the reality.
