your questions regarding the game rules (improving the interpretation).

The formulation can be based on the following statement: To break through one of the multiple guard towers (GTs) and/or a shifted GT inside the treasury, the trajectory when moving from one's spawn point to the treasury zone should be as short as possible and end on a cell near the GT to be broken. The first action in the treasury is breaking the GT. This rule also applies to cases where a GT is broken using air control.
