Gu Mian and Liu Ruyan were still discussing the motives of Group Three, while Group Four had already begun their move.
Apparently aware of the irregularity in Group Three's direction, Group Four's Chess Player hesitated for a long time before making a choice this round.
The best way to guard against an ambush from Group Three on Group Four's Chess Player is to withdraw the pieces back to near the starting room to protect the Chess Player.
However, the pieces cannot enter rooms they have already been to. To withdraw near the starting room, they cannot return the way they came; they must either detour or directly engage the pieces in the room where Group Three's pieces are present.
For some reason, Group Four's Chess Player did not make such arrangements, and from 007's report, Gu Mian learned that Group Four's pieces moved one square downward and did not return.
All of Group Four's pieces finished their moves, and the halftime commenced.
