As the "Om" continued to resonate within his body, Chen Nan initially responded with the "Om" Heavenly Sound to resist, absorbing the essence of the Heavenly Sound, and repeatedly correcting his own pronunciation to gain a deeper understanding.
About ten minutes later, the Heavenly Sound inside his body abruptly ceased.
Chen Nan's heart was tranquil, and with each repetition of the sound, the damage caused by the Heavenly Sound earlier had now completely healed, and his spiritual power had increased many times over.
This "Om" Heavenly Sound was indeed a technique for training spiritual power.
Calming down his somewhat excited heart, Chen Nan felt that the Heavenly Reversal Demon Technique was truly profound and truly deserving of the name "Heavenly Reversal."
He didn't know what the sound inside his body was all about, but he knew that this "Om" Heavenly Sound was like a tonic for himself, who was just preparing to cultivate his spiritual power.
