The second step was to successfully drug Mu Huan without even approaching her.
After she told that person about these two points, he provided her with this butterfly fragrance. He told her that if she used the butterfly fragrance alone, it would be a special fragrance that would not have any poisonous side effects on people. However, people who had eaten mackerel would feel weak when they smelled the fragrance.
Butterfly fragrance was a drug that spread in the air. It was very fast. By the time you smelled it, you'd have already been drugged. This was something that no one could guard against. The mackerel was harmless, but the butterfly fragrance was impossible to guard against. The success rate of the drug was 100%!
The man had assured her that the success rate was indeed 100%!
That person even said that there was no antidote to the butterfly fragrance.
