At that moment, Druid Poly, Druid Gunter, their family, and the 3 masters all heard a robotic voice emerging from the metal castle in the yard.
"The protection circle being attacked. Going into invisible mode. Levitation begins!"
Afterward, the castle door slam shut. It became invisible and quietly elevated towards the sky.
The 4 knights spent half a minute breaking Abel's protection circle by draining the 100 mana gems in the energy box.
This gave the battle fort enough time to rise 1000 meters above the ground. Even with the holy freeze aura, those knights could no longer do anything to the elves within it.
Mad Knight Joseph was the first one to penetrate master Bennett's place. He was confident that elves were hiding within. If not, there wouldn't be a circle with so much energy.
"Turn off the Holy Freeze. We can't kill Master Bennett, or at least try our best. We need him to make potions for us!" Mad knight Joseph said to his peers.
