All of a sudden, he broke free from the shackles and achieved a great liberation, a great relief!
Think about it—how challenging would it be to try and maintain the 'essence, Qi, and spirit' without any dispersal amidst such a remarkable breakthrough, and to charge through the barrier without any leakage?

A failed breakthrough would lead to a dispersion of the essence, Qi, and spirit, causing a huge loss of life potential energy.
