After getting forcefully reincarnated into a world of an otome game he has no clue about, the protagonist is then killed and brought back to life by the prideful villainess with one desire.

To rule the world.

As the ruthless girl’s Eternal Servant, how will he dodge the fate that the game system has in store for him?

What would you do if your planet ceased to exist after a nap?

Once upon a time, there was a princess…

Scrap that.

Once upon a time, there was a hermit called Yao Si.

She was an orphaned hikikomori who lived a peaceful and mundane life in her cosy little apartment.

Just when she thought she’d live out the rest of her mundane days… she died.

By a strange twist of fate, she was somehow turned into a vampire, even worse, a fifth-generation weakling with no combat ability at all.

Vampires had their own little secret society, cultural feuds, and called themselves bloodlings.

With the threats of another civil war among the bloodlings, Yao Si remained composed.

‘Even if this war of bloodlings rages on again, it will need a miracle to affect me,’ she thought.

So, a miracle occurred…

When she was woken up from a millennnia-long nap, she found that her beautiful mother planet Earth had ceased to exist.

Even the oldest bloodling in the entire universe was now one of her grand [ times infinity] child.

Everyone will have to call her “ancestor” from this moment onwards!

The peasant Yao Si had successfully revolted and taken charge, let’s see who dares to call her a weakling anymore!

“Hey! You, that guy over there!

“Yes, you.

“Come on, let’s fight, if I lose, I will call you ‘dad’!”

So… she has a new dad.

Yao Si “…”

Mu Xuan “…”

Rex was an ordinary salaryman, resigned to a dull life of monotony in a towering megacity. But his world shatters when he’s conscripted by Nexum Dynamics, a ruthless megacorporation, and thrust into a brutal war for a barren, alien world. The planet holds unimaginable riches, but it’s also swarming with the Krhyssari, an insectoid race that dominates the surface with their hive-mind precision and relentless aggression. Amid the carnage, Rex had an extraordinary encounter with Cleo, an ancient AI, a survivor of a long-extinct civilization. Cleo isn’t just an artificial intelligence; she’s a consciousness imbued with memories of her people’s interstellar empire and equipped with advanced bio-nanotechnology. Offering Rex a new purpose and unmatched power, she transforms his fragile human body into a hybrid of living metal and flesh, making him the ultimate weapon. But Cleo is more than a tool of war. As she journeys alongside Rex, her cold, logical algorithms evolve, shaped by his humanity. Together, they form a bond that transcends the boundaries of man and machine, discovering love in the midst of chaos. As Rex and Cleo fight for survival, they uncover a shared ambition, to rise as intergalactic overlords, uniting or conquering the galaxy.
