In fact, Jordan had referenced a setting in zombie movies he had watched. Daoist priests could use talismans to stick on the zombies' heads to suppress them.
However, there was no need to do so here, because even the zombie horned dragon was fake, so how could there be a talisman that could suppress it?
Wasn't it because Jordan could do whatever he wanted?
The reason why Jordan did this was actually to cause more mental damage to the golden-horned dragon.
Jordan had learned psychology from a famous teacher in his early years. He was already at the level of a psychologist. His grasp of human psychology and animal psychology were actually the same.
If he only created a zombie horned dragon to scare the golden-horned dragon, it would only be an elementary method to scare the dragon. If he wanted to make the golden-horned dragon even more afraid, he would first make it go from being afraid to not being afraid.
