Gu Shi just couldn't wait for Su Li to appear before him, even though he didn't particularly like her.
If things were going according to Master Cui's plan, Su Li's constitution should have been successfully transformed by now.
Although no one had tried it before, he had observed the process as described in those ancient books.
According to them, with Yin as the body, as a vessel for use...
There was a whole bunch of stuff that Gu Shi didn't quite understand, but he had grasped the basics.
Such a constitution was one in a million, but if successful, it could directly absorb the evil Qi from within himself and transfer it into the other person's body.
It also meant there was no need for that person to stay by his side twenty-four hours a day; just coming over periodically to absorb it would suffice.
This pleased Gu Shi greatly, as he was utterly sick of Su Li's lecherous eyes constantly sizing him up, and he couldn't even refuse her closeness.
