Chi Shengsheng's sword, if it had been anyone at the early stage of the Mountain Sea Realm, would have required strict preparation. Even though they had condensed three Divine Palaces, it would still have been the case.

Phoenix's Cry, when Chi Shengsheng broke through the Mountain Sea Realm, was invoked by the Heavenly Phoenix Song Technique he had practiced, capable of boosting speed, not limited to body movements or techniques, and could also have enhanced the burning effect in his techniques.
It could have been said that this was an extremely outstanding innate talent, laying a solid foundation for Chi Shengsheng's profound accumulation.
