Looking at the string of twelve level-5 Spells on the parchment, Mu Ying wished she could retreat immediately to study them, only resting once they had all been integrated into her strength.
However, considering that it took one to two weeks to master each level-4 Spell, the difficulty of level-5 Spells was definitely a lot higher; it was uncertain how long it would take her to learn them all.
She could afford to wait, but the development of her territory could not; she needed to take advantage of the fact that other territories had not yet accumulated enough funds to establish her Transmission Array network to secure the greatest development advantage for her territory. Otherwise, the coinage rights and ore vein rewards might fall into the hands of others.
So, retreating to learn Spells was not an option anymore.
