She comprehended the Immortal Spirit Great Dao and was nurtured by Spirit Immortal Palace, which was why she managed to reach the first level of the Divine King realm in such a short time.
Venerable Immortal Ling Yun and the others were very happy about this unique and ethereal Great Dao, and all felt that Ji Siqing would definitely reach the Creation realm in the future, which meant that the Spirit Immortal Palace would grow even stronger.
