The Silver Grandmother moved in complete silence, in what could be called an extremely insidious way.
She did not need any magics or any martial arts. With the strength an Invincible Vajra Level master possessed, it was almost too easy to deal with Zhang Teng.
Clang!
However, just as her walking stick was about to hit Zhang Teng, a pebble came falling from above, striking directly into the Silver Grandmother's walking stick.
The impact from the pebble left the Silver Grandmother's hands trembling right away, and she staggered backward from the force.
"What?" The Silver Grandmother looked at Lu Xuan in shock, as she did not expect him actually to be able to react in time.
She had not held back in her previous sneak attack on the unprepared Zhang Teng, and she believed that even if Lu Xuan were also an Invincible Vajra Level master, he would not be able to react to her attack.
