The Twelve Apocalypses: A Damned Soul's Path to the Abyss - Chapter 10: Customer Service

Sirens: a name derived from an ancient creature, used to describe those who could charm, lure, control, and heal others by singing.

Subjected to live the life of a siren, Aria had experienced, seen, and heard many horrific things. Broken beyond repair, Aria resigned herself to death, when suddenly…

The Grand Duke, Lloyd Cardence Valentine, arrived and whispered, “Should I kill everyone here?”

“If you need me, just call me. Your song will always reach me, wherever you are.”

In the end, Aria called the devil, bringing death to all those present, along with herself.

“Let’s fall down to hell together.”

And with that, Aria breathed her last and died… only to return to her 10-year-old self.

Now that she had a second chance at her life, Aria was determined to change her fate, as well as the cruel fate of her saviour, Grand Duke Valentine.

And so… Aria proposed to him with a marriage contract.

She sold her soul to the devil and vowed to protect him.

The young duke took the contract from her hand.

“So, where should I stamp the seal?”

“You said you’d divorce me within 10 years.”

The grown-up villain leaned in, hovering his head before he kissed her tenderly over her crown.

“Now that we’re adults, we should sign another contract.”

“I’m very talented, and I get twice the result with half the effort.”

“I am a genius that is rare to see in a hundred years, extraordinary in ten years, and holy in thirty.”

“My blood is against the sky, and I was born to be a king.”

Watching a group of geniuses arguing, Han Xu slowly closed his eyes and basked in the sun before falling asleep.

Diligence, perseverance, talent, resources, and opportunities are indispensable for the cultivation of others.

And he just needs to wait quietly for the skill to download.

A life without cultivation should be so unpretentious and boring.
