An Hao leaped, thinking she had died, but to her surprise, when she opened her eyes, she found herself back in the year 1985. To live a second life, did she have to endure the abuse of her stepmother and stepsister again, the dislike of her mother-in-law and disdain from her sister-in-law, and the betrayal of her best friend who bravely became the other woman just to slap her in the face and climb the social ladder? Was she supposed to end her miserable life in poverty again? An Hao's answer was, “Eat! Shit! No!” She was determined to make something of herself, to get rich by capitalizing on her knowledge and aim for a well-off life. This time around, she was going to be the protective big sister who reformed her worthless little brother who had died a wretched death, and the virtuous wife to make up for her past neglect of her husband! She wouldn't let this life go to waste in despair! A malicious best friend? Coveting her man? Not a chance! Go hang out wherever it's cool! Cough cough, how did she not realize in her past life that this “Stoic King of Hell” was so indecent. Decent? You've had your fill of decency during the day.

The Domain Of Gods exists!

For years, Cain searched for ways on his Modern Earth to travel to the world where beings akin to Gods roam about. Nobody believed he could do it, but Cain never gave up.

And after so many arduous years, he finally created the ritual that would transmigrate him to the Domain Of Gods!

When the ritual had actually worked, Cain should've been positively elated. He even managed to transmigrate into the body of a genuine Dragon Prince. But, there was one major problem.

Despite being the grandson of a Dargon God, he had zero cultivation for 18 years of his life!

But, instead of feeling despair or cursing his luck over such a cliche scenario, Cain welcomed this problem with a maddening smile.

Who cares if I have zero cultivation?! I will become a free reign expert no matter the means!

After reincarnating eight times unsuccessfully due to a glitch in the netherworld, Jia Hao finally reincarnated in the world of Urban Fantasy, an eroge game that he played before. However, he realized the game was currently in the bad ending mode and he is powerless like a side character without any game system.

As Jia Hao was wrecking his brain to how to change the plot, he found a mysterious pot that can take him into an ancient world, and the items he brought from the modern world transformed into heavenly treasures!

“Now, you dare to gaze at my women? My dear wives! Beat him to death!” Jia Hao ordered as he leaned back on the chair like a salted fish.
