Beside a stone wall, Xu Rongguang sat cross-legged, eyes tightly shut, at this moment, he was devouring yin souls.
The Earth Chart's Three-legged Golden Crow, this extremely yang and vigorous Fire Series demon spirit, has a powerful lethality against ghostly beings like yin souls.
Xu Rongguang, who has already condensed the embryonic form of his life soul, has half a foot already stepped into the Spirit King Realm.
His blood is also filled with yang power, which is why he dared to leave the gathering place continuously for three days to devour yin souls.
But even so, the process of devouring yin souls is still very difficult.
Each time is a wander between life and death.
Besides, Xu Rongguang must be very cautious in hiding his aura, constantly changing positions to avoid being discovered by other yin souls or alien races.
