Dungeon Overlord: Monster Girl Harem! - Chapter 55: Teasing a Dragoness *

Feng Lingxi was the traditional family’s head mistress – a person with a charismatic yet sly personality with the ability to attract people easily to her side, and having the potential to take someone’s soul away. Crossing across boundaries from a decade ago to now, a world that gives woman full respect and acknowledgement….

Don’t be fooled by her, because she was someone who would act obediently in front of a crowd but, stabs them in the back when necessary! Disguising as someone that would gain her trust and belief! That was why the Emperor of Xian started doting on her, allowing her to become absurdly daring to do whatever she liked. This made the Empress speechless to tears.
That would be the cause of the kingdom’s downfall in the near future…

Sullo was transmigrated to a world of High Gods. The people living in the world could light the God flame by condensing their believers’ faith to expand their god realm, forming their own religion to become a high god.

The god realm could be grown indefinitely by having more followers and absorbing their faith. A follower’s strength were closely tied to the gods they followed as well. However, unlike other gods, Sullo had a unique thousand-fold amplification system that made everything grow at a thousand times of their original speed.

A normal elf had evolved into an elf queen that could heal anything…
