Guo Youliang had a reason for such a guess, because the half of a human hide was always of limited size; if it was to attach to two people at the same time, then those two people must inevitably be connected to each other by the skin.
The two individuals standing before Guo Youliang, though with different appearances, had their shoulders tightly pressed together.
Guo Youliang observed carefully and a thought emerged in his mind, to catch them by surprise with the magnetic knife and separate the human hide between them.
By doing so, even if the other party didn't die, they would at least be severely injured.
The very next second, he swung the magnetic knife fiercely.
Since the two in front of him were already attached by the human hide, and were as good as dead, Guo Youliang had no hesitation whatsoever.
