Shangguan Qinger laughed coolly. She then turned towards Su Yu and said, "End this battle quickly. Kill that little thief!"
Su Yu nodded his head slightly. All of the air in the space had already become concentrated within his palms. Moreover, the space surrounding his body had become an air-tight vacuum, such that not even a sound could penetrate it.
The compressed air in his palms was visible to the naked eye. As it became increasingly compressed, it turned from an initial cloudy green to a darker green color. It then turned from dark green to dark grey. Finally, once the air was compressed to the size of a thumb, it suddenly became a dark black color!
Within the black compressed air, there were rumbles of thunder, which had formed from the highly compressed state of the air and the collisions between the air particles. The destructive power contained within the small ball of air was something that had never existed before!
