Sacred Sound Heart Refining Pool.
108 Sutras.
In a normal Taoist cultivation trial, these 108 sutras are recited gradually, refining the inner strength of the Inner Sect Disciples of the Outer Heaven Palace.
A strong individual can accelerate the recitation of the 108 sutras, but they must complete all of them to pass.
Just now, the True Disciple of Outer Heaven Palace, Pang Xuan, spent an hour completing the Heart Refining Pool.
This means that Pang Xuan endured all 108 sutras in just an hour.
This endurance is not simple.
During an hour, the mystical sound of each sutra becomes exponentially powerful due to such intense compression.
More terrifying, the mystical sound, compressed and amplified, is the superimposition of the 108 sutras.
This is why Xie Tian, observing the records, felt his heart fluctuate continuously.
