In reality, Ye Shikai did not leave the market but was sitting in the car staking out, equipped with an ultra-high-definition camera that recorded every person who appeared, storing it into the computer. This was a device and software that Worm spent a month developing. If there were a phrase to describe this system, it would be "never forgets a face".
Any face captured by the camera would be recorded and registered, and when they appeared again, there would be an alert. This system could effectively tally the number of people in the entire timber market, even a masked demon exorcist would be captured.
As per his request, National Security Bureau members had already installed hundreds of cameras throughout the market for full coverage without any blind spots. Unfortunately, up until now, there has been no trace of the demon exorcist.
