Before having the first round of sex with Cynthia, the Tower informed Kent that she possessed enhanced yin qi, something that shouldn't have been possible for someone at her level.
Then, after the happy time and Kent finally unlocked the seal on his cultivation, his cultivation base shot through to the Root Grandmaster stage instantly.
Moments later, the Tower awakened and revealed that Cynthia carried one of the most powerful bloodlines imaginable. However, since her bloodline hadn't yet awakened, it couldn't determine its full nature.
Still, the Tower, with its wealth of True Names—meant to unlock hidden potential—made it clear to Kent that her path would inevitably awaken once she is added to the Tower and some requirements are met.
He didn't expect that awakening to occur immediately after adding her to his harem.
On the bed now lay a naked Cynthia, her body beginning to glow intensely like a radiant bulb.
