Once inside the room, Xu Haishui glanced at the female zombie nailed to the ground, a strange look flitted across his face. Then, he started to explain the principle to Tang Ye.
He was himself a zombie that evolved towards the mental aspect; he had some understanding of controlling the ones that came and went.
"You've controlled zombies before, so you know what it feels like. What we call 'control', only exists when high-level zombies take control of the low-level ones, making them accept our will and controlling them!"
"You may be confused, but I understand fully. As I said before, it's about memory. Yes, memory…" He seemed unable to continue. Even though Xu Haishui had some insights into mental control, explaining it to someone else requires good communication skills. So he got stuck, his tone changing chaotically and he fumbled for words.
