Wang Tao, to prove his hypothesis, used several mental attacks on Xu Xiaojun, each time intensifying the force.
The results were mostly as Wang Tao had guessed—if most of Wang Tao's mental attacks went practically unnoticed by Xu Xiaojun, it was only when Wang Tao increased the force that Xu Xiaojun felt the attack, but it was just a slight sensation.
Although Wang Tao's skills in mental attacks were not yet proficient, such attacks would have caused significant HP loss to anyone else, yet on Xu Xiaojun, they were barely noticeable…
Moreover, this awakening of Xu Xiaojun was not an active one but a passive one, which meant it didn't consume any energy! In other words, his incredibly strong spiritual defense power would always be there!
"Should we test the limits of Xu Xiaojun?"
Wang Tao thought about it, then decided against it.
