According to the analysis of the life-bonded magical treasure IBMz15, a Great Elder Level Body Refining Golden Core cultivator's defense was nearly impregnable.
However, there was no absolute defense, his mental weakness had been very obvious before.
Of course, the mental weakness of a Great Elder Level Body Refining Golden Core cultivator is relative. Compared to other Golden Core cultivators, even those of the same level, his spirit was deemed adequate.
But facing a cultivator like Li Shiming, who had mastered spiritual attack secret techniques, his spirit appeared somewhat weak.
Indeed, after "Heavenly Demon Entering the Ear" broke through his defense, the melody of the "Heavenly Sound Annihilation Dao Zither" took effect.
The "Annihilation Melody" led him into an illusion, Li Shiming seldom used the "Heavenly Sound Annihilation Dao Zither" to draw enemies into illusions.
