In fact, most Fey warriors focused on cultivating their lifeblood. Just like Heaven Earth Yuan Qi were related to laws, lifeblood powers were related to the body. Lifeblood could both nourish a body and be released as an attack.
The Fey cultivated in their lifeblood and had the advantage of their bloodlines. This was not something humans could compare with. Furthermore, the Fey also endorsed tough combat styles.
Most Fey warriors were unwilling to cultivate in mystic arts or array formations. It was the same with the Luo King.
He was a genius when it came to the aspect of bloodline in his youth, so his lifeblood powers left others in the dust. But his mystic arts were much inferior to others.
This was also the reason why Princess Chang was unhappy with Luo King.
Although Princess Chang did not say it out loud, Luo King could sense her attitude and guess at what she was thinking.
