The Only Aura User In Magic World

While I was digging to make the place bigger for everyone to sit on, the earth spirit came and greeted us. He noticed us appearing here, but he told the earth dragon first before he came here.

"We're planning to do it in about one week. So, these girls have something to ask you before the fight," I said.

The ones who needed the earth spirit's help the most are the girls. So they will be the one asking him for help.

"Earth spirit. With only one week to attack, we would like to grow stronger no matter how little improvement we make. So please let us cultivate in your presence. Reaching master level will be difficult in a week, but at least we can get a bit stronger before the fight," Kayla asked the earth spirit for a favor.
