The Troops Were Ready!

Back in the third army camp.

The morning after Leon and his troops defeated the 3rd ambush army, they quickly moved to account for the spoils left by the armies and evenly distributed it to each member. 

This is to ensure that even if something happened that made them separated from the group, they could survive for several days even without access to their original supplies. 

As for the mini bird cages, it was quite convenient that all those inside Leon's bird cage spell would enter a state of animated suspension, where they would simply stop all their bodily functions until they were woken up. It is the same array spell mechanism embedded in Carolina and the other main criminals in the Court of Sinners.

As such, until the Emperor decides what to do with them, they will remain asleep only to be awakened at specific times to barely replenish fluids and nutrients in their body.
