Generally speaking, the lingshi in Xian Xia's novels mostly refers to jade, and the essence of jade is said by ancient books to have the effect of air-entraining health preservation, which is the source of lingshi in novels.

Generally speaking, lingshi is a jade that has been gassed for a long time. According to the quality of jade, it can be divided into three types: low, medium and high. You can understand that lingshi is jade, and then the better the quality of jade mined in mines, the better lingshi will be.

This reason is normal. Many Xian Xia novels have realistic backgrounds, and all sects have secular families running around for their normal lives. I hope this understanding will help you.
