Another piece of the metal substance was not far from Jia Yan, hovering about two thousand meters away in mid-air, and it dared not advance any further!
It was terrified!
Jia Yan was distinctly joyful about this.
With a turn of his body, amidst the faint roar of the sound, he left the airspace above the research institute!
"My goal tonight is simple. I am testing the attack range of this creature or object, and whether it possesses intelligence. As far as I can determine now, both its forms of attacks have a distance limit. The metal substance can break through three times the speed of sound, but the object controlling them has a range of only two thousand meters. As for the earlier sound attack that almost caused me to faint, it poses a lethal threat to me only within a hundred meters,"
Jia Yan stared at the landscape behind him and seemed to fear the threatening research institute a little less, revealing a slight smile.
