Again, Lan Wangji does not answer. The reason for this should be clear: he is occupied. It would be foolish, at this point, to try and track each ball's movement around the cabinet. That would lead only to distraction. It is like the second siege of the Burial Mounds. When one is beset by an unreasonable number of foes, it is possible only to react to each one as it approaches. He fixes his gaze on the flippers and sends each approaching ball flying crisply away.
