Shi Mu closed his eyes and stood completely motionless. It seemed as if he was absorbed in thought, and he appeared to be recalling something important.
Some time passed. He then raised his right hand, and another mass of fireball emerged out of thin air. It then darted towards another square-shaped boulder.
A burst of fluorescent radiance gushed into Shi Mu's eyes as he saw the fireball was on the verge of touching the surface of the boulder.
Then, a burst of tiny and hazy fluctuation occurred in the void. After that, a long and slender invisible chain emerged. It then formed a connection between Shi Mu and the fireball.
Shi Mu's mind moved, and the fireball abruptly halted in front of the boulder. It had stopped barely a foot away from the boulder.
Then, the fireball turned in a swift manner, and bombarded at a spot behind the boulder. Masses of flames flared up along with a loud explosive sound. And, layers of stone fragments scattered in all directions as a result.
