Qin Liuxi didn't kill Daoist Yin Shan, but instead used silver needles to pierce his acupuncture points, causing confusion in the meridians of his brain, resulting in memory failure, commonly known as brain damage.
After this acupuncture, he would still know everything he had learned and how to do it, but when he actually tried to implement it, those memories would collapse and not come together, let alone how to do it; he couldn't even speak of it.
This act was essentially the same as ruining his cultivation, but Qin Liuxi was even more cruel. She left him with all the knowledge he had, but he was unable to act, only able to be anxious.
In other words, she had trampled Daoist Yin Shan's pride under her feet.
Kuang Shan: The title of Evil Ghost should be reserved for her.
