The members of Emerald Hand at Stage Two-Pointed Star tried to destroy the tree dome, but they couldn't. It was no ordinary tree. Otherwise, they would have shattered it in a single blow. The flute's melody could control and summon the tree, and it was powerful and malleable.
The light mages thought Evan was trying to escape, but in fact, Evan was preparing a deadly attack that would end their confrontation. He decided to enlist the help of the 69th demon, Marquis Decarabia, only now for several reasons.
First, without the help of the 67th demon, Duke Amdusias, he wouldn't be able to create a tree dome, and the mages would be able to escape from his attack. Secondly, the surviving mages were now severely wounded by their allies. Evan thought that a hundred mages would be able to block this attack, but right now, they didn't stand a chance.
