Otarais' method is simple. Since Divine Blood invades and devours the original soul, this is essentially a war happening on the mental level.
One way is to eliminate Divine Blood, but if that's not feasible, then considering another way is also worth trying.
The suggestion from the Heroic Spirit of the Female Knight is to find a way to strengthen Qian's soul.
And when it comes to strengthening someone's soul, undoubtedly it's about training the power of the soul and spirit. In this aspect, few surpass Wizards and Elemental Mages.
Otarais told Brand that she remembered another special use of the Golden Apple, which suddenly gave her this idea. Because the Golden Apple is also known as Fairy Language, the most precious gift to Wizards and Elemental Mages.
However, even if one uses this method to temper the soul, it's not a simple task. For indigenous people like Qian, leveling up isn't as easy as it is for Brand, who just needed experience to soar; this requires a long process.
