Zi Yi and Lu Jingye did not have to wait long before they saw Zhang Hanyu's car driving out.
If Lu Jingye wanted to follow a person, he was capable of making it so that the other party would not notice anything.
Unexpectedly, Zhang Hanyu had directly returned to the residential area where the faculty and staff of M.Uni resided at. They did not notice anything out of place.
Lu Jingye parked the car at a building slightly further away and after waiting for Zhang Hanyu to enter the building, Zi Yi took out her phone and connected to the surveillance cameras in that building.
There was a surveillance camera at the entrance and exit of each floor's corridor and Zhang Hanyu lived in apartment 505 on the fifth floor.
Everything was normal.
Zhang Hanyu unlocked the door and went in.
Zi Yi directly hacked into Zhang Hanyu's personal computer and secretly switched on the camera function.
