I am a vampire, possessing the body of the villainess in the novel.

I want to live quietly so I can live peacefully.

When I saw the Duke of Esteban, I lost all my reason and bit his neck.

Duke of Esteban just so happens to be the greatest figure in the empire.

I didn’t have enough strength to fight the desire, so I slept with him…

I’m in trouble. Let’s erase his memory and run.

“Your Excellency asked me to convey a message ‘I let you have my neck and body, but you threw it all away and ran.’”

What are you saying?

Does he remember?

Later, there was a strange declaration of war after we met.

“Don’t avoid me and let’s continue to meet. Also, when you need blood, come find me.”

Duke, would you please stay away from me?

It’s hard to breathe because of your taste.

A long time ago, the decayed main god space collapsed and disintegrated, and the wreckage was scattered in parallel universes, giving birth to a new space…

Countless ‘story worlds’ under control have also fallen into the void, regained freedom, runaway out of control, elevated to reality, and turned into reality.

At the same time, these “worlds” are polluted and corroded by the void, giving birth to greater fear and filth…

…

The space of birth feeds on the world.

They compete with each other, their tentacles penetrate through dimensions, invade different time and space, search for the legacy of the main god, drive the apostles to be minions, greedily tearing, seizing, devouring, and reclaiming one world after another, so that they can return to greatness.

…

The innocent eating melon and white waves with the legacy of the Lord God accidentally got involved in the parallel universe “Paradise of Fire” during a cross-border call.

After forcibly binding the demi-human blood, he became an excellent tool man who can repeatedly die, starting the legendary ‘dimension invasion career’.
