The eldest senior brother immediately clutched his head and began to roll on the ground in agony.
The Heavenly Sound Demon Suppressing Skill indeed had the ability to suppress the mind demons of cultivators, and when performed by Shu Guan, who had now reached Nascent Soul status, its power was truly unparalleled.

The occurrences on the eldest senior brother's body were too peculiar; Shu Guan couldn't guess the reasons, and all he could do at that moment was to keep shouting at the eldest senior brother incessantly with the Heavenly Sound Demon Suppressing Skill.
After all, that one shout had seemingly brought the eldest senior brother a moment of lucidity.
