This is also due to the Jade Phoenix Tree Seeds Jiang Daozhen gave him, which are the most effective twenty-three-year-old Parasol Tree Seeds. He's not one to hide things; good stuff should be put to use when needed.
If Xiaopang were to consume them, one seed per month would suffice, and the spiritual effect would mostly be wasted; if He Kao uses them for cultivation, he needs to manage it himself, taking one seed every five days to a week, maximizing absorption of the spiritual effect.
He Kao didn't give the Jade Phoenix Tree Seeds to Xiaopang; instead, he continues to let Xiaopang consume the Peiyuan Pill. Having the Jade Phoenix Tree Seeds means He Kao no longer needs to consume the Peiyuan Pill, leaving the remaining bottle entirely for Gao Xue'e.
While cultivating, he also secretly pays attention to suspicious individuals around him, and indeed he discovers one—it turns out to be a colleague from the company.
