Along the way
Very few people were aware that the Wang Consortium had a black screen where the names of those that appeared on it ended up either dead or in prison.
Under normal circumstances, Zero only displayed the results of two functions on this screen. One function pertained to the upholding of internal security, and this meant the names of all prisoners and spies that were discovered would appear on the screen. Afterwards, it would inform the Public Order Division or the intelligence agency to handle the matter.
Zero would call them on its own, speaking in a voice that either belonged to a young woman or a middle-aged man. Although a lot of people who received the call knew of the artificial intelligence's existence, they would think it was a real person who called them.
