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.

Before Yao Si could process the situation, she felt her body getting heavier and her entire being submerging under the water. The bubble helped keep the water out as the little merman pulled her deeper and deeper.

Gradually, she started to make sense of the surroundings. Unlike what she had imagined, there was a huge city down underwater. With a sweeping glance, she took in the assortment of architecture and crowded roads filled with mermen of many unknown species swimming in big groups. Some species were even as big as whales!

Yao Si felt as though she had been transported into a sci-fi movie. By the time she regained her senses, the little merman had dragged her to a crystal-like palace with a big sign at the front: Mermen Marriage Registration Centre

He was serious about registering their marriage!
