But after his cheat system activated? "Low-tier? Fine, whatever."

As a demon monarch with standards, Zhou Mingxuan’s first self-assigned mission was clear—

"How to Cling Tightly to Hestia’s thick thighs (and Her Blue Ribbon)!"

Of course, thick thighs had their charm, and long legs their appeal. The Demon Lord wasn’t about to refuse more goddesses lining up to spoil him…

"Ding, congratulations to the host for awakening the "Many Children, Many Blessings" system."

Think about it, I am a grown man. Although the power of my family bloodline is gradually declining, have I been reduced to relying on having children to change my fate?
