Thinking about it, Qiu Gaohe was scared to the point of suffering a choking fit thanks to Ling Chuxi the last time. Since losing all of his reputation and suffering a loss, he would also surely have found a countermeasure after such a long period of time. There was a need to switch to a new method.
Poison was still poison, but as to how to use it, that was another matter.
Ling Chuxi quietly retreated and found a suitable spot to set up a trap before scattering poisonous powder over the whole area. Luckily, the last time she exchanged blows with Chu Fengyun and the rest, Wu Feng Hall's thousand over people were dedicated to their performance and Ling Chuxi also very cooperatively waved her hands emptily for quite a while. Otherwise, no matter how much poisonous powder she had, she would have long since scattered it all away.
