Cha Cha the rabbit's plan was simple: since the path on the ground was difficult, they wouldn't take it.
Cha Cha the rabbit pointed to the gaps in the wall bricks, "Just like we did when we climbed the chimney before, we'll move across by the brick gaps bit by bit."
After listening, Angel shook his head: "Climbing using the brick gaps has some merit, but there are many variables midway."
The two most important variables are the limits of physical strength and time.
With Angel's current endurance, it may not be enough to reach the right side of the main hall. Moreover, the main hall is actually quite large, even not considering stamina, just with their current size, it would take a very long time to reach the right side.
Once time drags on, the risk increases. The maid who poked her head into the small window might pull back, the maid eating cockroaches might give up searching, and the patrolling maid who went out might return.
