In between the cultivation sessions, Alex had come across a problem that scared him. And the problem was that the Yin bead hadn't truly gone dormant.
He wasn't sure what exactly happened, but the Yin bead would pull Qi from his Golden Core, pulling it into itself to generate more Yin Qi.
So, when he took a break from absorbing Yang Qi, the bead would make more Yin Qi when he wasn't fighting it.
Thankfully, the rate at which it happened was so low that it wouldn't even go through 10% of his total Qi capacity in an entire day if he left it as is. When it did go through the 10% of Qi, the amount it would produce would be just 1% in return, but the Yin that did come out would be a grade above normal.
1% or 2% wouldn't do much for Alex, but if he was to go on a few days without cultivating, then the Yin Qi would start causing trouble.
