It's not like it was a wooden fortress though!
The siblings just put out the prepared tree's barks in front of them, lining them up and wide like some kind of wall... Naturally, every tree's bark had the new technique, but it's not like Daria and Guri would say it loud.
So in the utmost obliviousness...
"""Seriously?"""
Every leader muttered in unison! They felt like laughing yet they couldn't!
Just how poor were the siblings?
Maybe they have truly used everything in the volcano to take down the first vermillion birds from their army that arrived here few days ago?!
If that's the case, then their efforts could be only pitied upon!
Not feeling like laughing or crying, every leader muttered the name of the technique once again! It caused the red flickering tail spears to shot forward!
"There is an army! The fire of united and honed by battle and killing intent warriors!"
