MTL - Valkyrie Domination - Chapter 5316 this is baby

On the Great Land of China, forces clashed for the sake of supremacy and Bloodline Warriors ran amok; the conflict of the strong threatened to shatter heaven and earth. A young man named Lu Li—nothing more than a humble Coffin Carrier from the Northern Desert—came along with Lu Ling, his sister. The two were regarded as puny insects and bullied, but little did people know that Lu Li had the strongest Bloodline of them all in him.

He mounted the most handsome of horses and drank the strongest of wines;

He bedded the most beautiful of ladies and murdered the most hated of people;

He told a huge lie and carried with him an ill-reputation undeserved;

He traveled all by his lonesome and danced with devils;

He had given his word that he would come back, that he would be strong.

And it was because of this that she was still waiting in the city—alone.

The story begins similarlly—a mid-level corporate worker dies and awakens in another world as a 19-year-old—but from there, Eren follows a very different path.Erik, a mid-level office worker, had a simple dream:“Graduate college.Get a job.Screw MILFs.”But reality wasn't so kind to him. Due to his hastiness, he forgot to check the company's background and accidentally enlisted himself into a black company—a corporate hellhole that literally made employees work to death.Such was the fate of our protagonist, Erik.Exhausted after working nonstop 12-hour shifts for seven days straight, he lost his grip on reality and met a meaningless death, collapsing onto his desk in an office nobody would mourn.Yet, reality wasn't entirely cruel either.He suddenly transmigrated into the body of an 18-year-old—young, energetic, muscular, and brimming with vitality. And best of all?He woke up sleeping right next to someone!“What? I'm transmigrated sleeping right next to my step-aunt?!”Even crazier: in this new world, beauty standards were completely reversed. Here, the pinnacle of femininity was a skinny figure with small boobs and an even smaller ass, and women who didn’t fit that mold—busty, curvy MILFs—were mostly ignored, discarded, and lonely.“How crazy is that?” Eren voiced, grinning from ear to ear.But all of that was about to change, since he was here now. He'd make all MILFs his—starting with his deliciously thick, step-aunt.

A wicked mother one day brought home a girl. The child was the hidden legitimate daughter of the duke, the heroine of [The Duke’s House Has Three Sons and One Daughter] Loretta. I was Melody, the villainous girl who tormented her and was condemned along with my mother. Not wanting to die like that, I decided to start treating her well now. I personally fed Loretta, put her to bed, and played with her. And then her reaction was…? “I want Melody to marry me!” Caught off guard by her endless affection, I too ended up entering the duke’s family, “I’ll stick right by Miss Melody’s side.” And there, it seems I’ve met a young lord who’s an even bigger ‘Melody fool’? All I did was be kind to survive, but why am I being loved…?!
