In the past, Wei Wucai had explained to Yan Zhiqing about the Hidden Light Unit.
Missions completed by the Hidden Light Unit were extremely difficult.
Members of the Hidden Light Unit would have to collect all sorts of information and plan thoroughly before the start of the mission.
They had to consider all scenarios.
They also had to plan their escape.
They also had to keep track of their target's location for a very long time.
They had to figure out every little detail and habit that the target had acquired over time.
This ensured that the success rate would be above ninety percent.
There were so many things to prepare for before the mission…
So, members of the Hidden Light Unit would take a long time to complete a mission.
