At this sight, he was once again stunned. This skill... It's freaking awesome!
As the name implies, surveillance repair is the repair of surveillance systems, but what's heaven-defying about it is that as long as there's a surveillance camera, even if the device is actually broken, Old Tang can use his skill to retrieve footage from a certain time period in the past!
This was already somewhat mystical, even bordering on pure creation from nothingness!
Because originally, since the surveillance was broken, it shouldn't have been able to capture anything, but after the skill's repair, it could indeed bring up things that weren't captured before.
The reason it's called "pseudo" is mainly because there must be a surveillance camera present, and the video retrieval must also be from a time period before the coverage of the surveillance.
Despite that, this still ranks among the top tier of miraculous skills!
