Leveling up the World - Chapter 973: Alone no More

Mu Jingzhe transmigrates into a book filled with sweet, doting love to become the useless supporting character who serves as a foil to the female lead. She also becomes the stepmom of five kids to her recently deceased husband.

No family, no power, no inheritance — a thrice-lacking protagonist. Just how will the seed rise up from the mud?

“I’m no angel, baby girl. I’ll make you cry, curse, and scream every night once you’re mine. So think twice before you sign this goddamn contract.”+++Rivana Faye thought nothing could get worse than catching her husband and step-sister making out on their wedding anniversary, only to be shot dead the same day.Instead of the afterlife, Rivana woke up back in the past, on her wedding day, staring right into the eyes of the same bastard who had ruined her life. Fueled by vengeance, she planned to marry him and tear his world apart, just as he had done to her in her previous life.That is, until Azrael Dynar, her supposed husband’s older brother, stepped in with a shocking claim: that they were already married?!“Wifey, are you cheating on me with this tiny loser? Tch, you have poor taste,” Azrael drawled, flashing their marriage certificate to everyone's horror.Azrael was everything Rivana had heard in hushed whispers: cold, cunning, and irresistibly seductive. But to her, he was oddly caring and fiercely protective. He even vowed to destroy everyone who had hurt her as long as she continued to be his side, as his darling wife!And the deeper Rivana sank into Azrael’s world, the more her defenses crumbled, leaving her with nothing but growing desires for him. Little did she know, the man she was falling for was no guardian angel but a devil—one responsible for her death, and the very one who could destroy her all over again.---Excerpt:“You seem to have experience in seducing women, Mr. Dynar,” Rivana joked, licking her ice cream.Azrael smirked at her laugh, and the next moment, he pulled her chair closer, causing Rivana's heart to skip a beat. Before she could catch her breath, he suddenly captured her lips, tasting the sweet chocolate on her lips.Pulling back slightly, Azrael smiled, enjoying her reaction. Tracing her lower lip with his thumb, he declared, “You are the first woman I have ever tried to seduce, Rain. And you will also be the last.”
