It seemed that the turtle shield's area of coverage wasn't big, and it didn't have the same ability of my shields to surround a space and defend those inside it.
In brief, this shield was like an immovable rock that stood in my path. I could simply take a detour, turn around it and continue deploying my shields.
But I already grew tired of doing this. I controlled enough space to start my next step in my plan.
So I didn't aim towards deploying more shields around and simply led the enemy to mistake my inability to overcome such obstacles.
During the next few minutes, I reinforced my shields by adding more to them. It was a must to do move, or else my next move would lose much of its value once my shields were taken down.
Such a turtle shield might possess some sort of offensive power in it. If so, then my shields were at a great risk of getting smashed in a short span of time.
