The "Brother Gu" mentioned by Zhao Qingshu is named Gu Ruoxu, and he is a disciple of Qiankun Academy.
He possesses the Space Divine Body.
One of the Eight Divine Physic, the Space Divine Body!
The technique of Body Melding Void used by Ling Chen closely resembles a secret technique of the Space Divine Body.
This is why the Great Emperor of Qiankun Academy and Zhao Qingshu were surprised.
They had personally witnessed Gu Ruoxu use it.
Actually, this Void Body Refining Technique was derived by Jiang Taixu from the Void Secret Technique of the Space Divine Body.
He made some improvements so that ordinary cultivators could also practice it.
The improved magic skill is the Void Body Refining Technique.
How did Jiang Taixu come to know the Void Secret Technique of the Space Divine Body?
Because he was the previous holder of the Space Divine Body!
This Void Refining Technique is actually possessed by all Eight Heavenly Sects.
However, very few can successfully master it.
