alright so red Soule devouring flame is similar to fire of Agni. so what is the connection? did Agni create the red flame? Also she is daughter of Agni. but her father is not Agni or related to Agni. however he is a fire mage. We know that Bai shiling has daughter of ruler of matter and she received records from Bai zemin who is ruler of all matter. Wu yijun also has daughter of Gaia but her parents, one is flaming warrior and the other is danger and charm embodiment so they are unrelated to Gaia. so the only reason I could find to daughter of title is that somehow records are that maybe somehow Gaia gave records to Wu yijun in secret before the Soule record reached Earth, same goes for feng tiang Wu
