While both Duke Darcy and Julia are busy defending Elaina, Elaina quickly goes to do her work and makes sure that everything works properly without any mistakes.
Getting the mana stone in her bag, Elaina put a few on the soil to the tree's roots. At first, Elaina thought that it would take a few days for it to work, but before she could even put the other mana stones, the first mana stone she put suddenly melted into a bluish liquid and slowly seeped to the ground as the tree started to glow faintly. It isn't glowing too much but it is showing the signs.
Seeing it work, Elaina didn't waste her time and put the mana stones one by one to the ground and let them seep straight into the tree which consumed the mana stones at a rapid pace. It didn't take long for the mana to completely envelop the whole tree and even Julia and Duke Darcy took notice of it while they were fighting.
