Once the diligent servant of the Elven race, Bai Qi is betrayed by his fiancée, the Elven Princess, on their wedding night.

A cheat ability arrives late.

As if by a twist of fate, Bai Qi finds himself becoming the leader of the Night Elves.

The truth that has been sealed for a thousand years on the Lulucia Continent is about to be unveiled:

Is magical civilization an invasion? Is the civilization Bai Qi brings with him also an invasion—or perhaps they’re both invaders, or something even more?

Within the mists there are yet deeper mists.

The sun may set, but the night shall never end~

The Eternal Night Empire!

Monsters, once wantonly slaughtered?

“From now on, slimes are the mascots of the Eternal Night Empire!”

s*aves, trampled at will?

“Wherever the Empire of Eternal Night shines, all are equal—every race, every person!”

Why?

The Industry of Eternal Night: Elven firearms, steel behemoths, rulers of the sea, kings of the sky, orbital star annihilators…

“From this moment on, I will never allow anyone to raise their voice at me again.”
