Here's the edited version of the chapter with corrected grammar and spelling errors:
Yui had stopped her Kundalini Yoga [1]. Even for her, it was a rather dangerous practice, and now that she was completely focused on Shuri, she had a hard time avoiding mistakes.
This yoga was practiced by humans as well, as cultivators spread the initial and simplified version in the hope of finding more seedlings. But sadly, the results had been subpar.
Each generation of humans was worse than the last in terms of potential, and because of the pollution and destruction of nature, the Prana and the power of mystery were thinning.
They were already in a period of great drought where most celestials, such as fairies and Yokai, avoided staying too long on Earth as the air was more akin to poison for them.
Sighing as she felt heat spread through her body and her muscles twitch, Yui asked, "So, who is it?"
"My half-sister."
