When Yuan Ju saw the men and dogs boring down on them, he had to make a split-second decision, or they would all be in deep trouble.
Yuan Ju's mind moved fast, and the second the four men came into throwing distance, his action of drawing his gun turned into throwing a smoke bomb rapidly. The smoke bomb made a short parabola in the air and dropped to the men's feet with a soft clink and rolled on the ground.
At this time, one dog just ran up to their side, and he took advantage of the opportunity to help his men block the blow.
The four men who ran out were startled by the round thing falling from the air and, at first, thought it was a grenade and hastily retreated from this side.
However, they were only surprised for a second and then reacted. Since the intruders threw it at their feet, it couldn't be a grenade, especially in such proximity; they would all die if the grenade exploded–Nevertheless, it was too late to advance again.
