When Wu Yan was hunting the evil disciples of the demonic path, he had specially chosen many evil disciples of the various demonic sects. This way, they would come looking for him.
After all, Zhu Wuan had killed such a famous expert in their sect. As a large demonic sect, how could they not give their disciples an explanation? Otherwise, who would join these large demonic sects in the future?
Faced with such an open scheme, even if these large demonic sects felt that something was amiss, they would still fall for it.
In addition, Zhu Wanhao deliberately showed weakness. Every time he encountered a large number of demonic experts ambushing him, he would retreat as if he was very afraid, allowing these large demonic sects to 'speculate' his strength.
