[Hot-Tempered, Cocky Merfolk Girl x Narcissistic Exiled Immortal Ancestor]
Meng Huaizhu was reborn. In her previous life, her entire clan was slaughtered, and the South Sea ran red with blood, all to protect their last sacred pearl.
Before she died in her previous life, she endured every kind of torture. What did she have left to fear in this one? Given a second life, she decided to let go of her obsession. She'd do no good deeds and only look out for herself!
To hell with the sacred pearl. One slap would crush it and put an end to all this nonsense!
After cultivating for ten thousand years, Wen Yezhou became an immortal. Little did he know that the merfolk pearl he'd left behind in the mortal realm in his previous life would bring about a catastrophe. The old Emperor ordered him down to the mortal realm, saying, “Don't come back until you've pacified the South Sea!”
The Immortal Palace was boring. As if he cared about staying in the heavens!
On a return visit to familiar places, he went to Longxiao Palace by night and came upon a mermaid sneaking into the sacred hall.
Well, the sacred treasure was priceless, so it was bound to attract covetous eyes... Wen Yezhou hadn't even finished that thought when he saw the mermaid glaring furiously and brutally trying to crush his clan's sacred treasure.
“Stop right there!”
The mermaid looked up at the sound. Her jade-green eyes were as cold as a deep pool, and the light glinting off her blue-gold scales was dazzling. She opened her mouth and brazenly declared, “Even the King of Heaven himself can't stop me today!”
That's right. I am the King of Heaven himself!
