Although this was Han Dong's first time participating in collective training, he might not understand many 'hidden rules'.
However, looking at the introduction of the rules by Deputy Commander Heidler.
The Knight Regiment NPCs scattered throughout the manor will only provide some of the most basic tasks, and the points that can be obtained are relatively fewer.
Of course.
Teams must rely on this series of basic tasks to slowly touch into the 'surface secrets of the manor' and explore deeper over time.
And to touch the intermediate, advanced, hidden series of tasks, or the most critical [core tasks], you need to finish a large number of prerequisite tasks, or find certain props or clues on your own.
Variability, randomness, and a progressive exploration mode from shallow to deep.
Han Dong could infer the Knight Regiment had been to the [Stuart Manor] long before.
