When Su Yu attempted to use the mental power of the Earth Treasury Undying Sutra to influence the Palace Master of the Huofeng Heavenly Palace, he could clearly sense the Palace Master's strong spirit and will resisting determinedly.
An exalted one at the peak of the Dividing Spirit Realm, and also the master of a single palace within such a powerful force as the Huofeng Heavenly Palace!
The Palace Master's foundation and heritage within the exalted ones of the Dividing Spirit Realm could also be considered at the absolute pinnacle.
If some trump cards were used, perhaps an Initial Stage Hollow Void Realm Daoist Master would find it difficult to kill the Palace Master of the Huofeng Heavenly Palace, and at most could barely contend with a Hollow Void Realm Dao Master briefly.
This was the true strength of the Palace Master of the Huofeng Heavenly Palace.
