All of us proceed after we broke through the steel door. There were supposed to be some expert level earth mages in the fight in front of the door. But none of them managed to break the door. That's just shows how powerful Celestine has become. Even Angela asked her to teach it to her later. And Sara who is still an advanced level earth mage is also interested.
As for Kayla, once she heard about it, she will ask Celestine about it. And then, she will ask Victoria and learn it in no time. Soon, Celestine won't be the strongest earth mage we have anymore.
Well, I doubt about that. Kayla is still focusing on her healing element and light element as well. So, Celestine who only need to focus on her earth element might still be able to get stronger.
"Let's proceed. Shelia and I will be at the front, and Graham will be right behind us. In the middle, Celestine will stay with Candy and Wendy. After that, Sara and Angela will be on the back."
