Sin System: Demonic Harem After Reincarnation - Chapter 36

In her previous life, as Yun Xi lay on her deathbed due to a terminal illness, her famous painter husband said to her heartlessly, “Yun Xi, let’s get a divorce. I would never marry you if I knew that your sister was the one who saved me.” Yun Xi was dumbstruck. It was actually her who saved Mo Ran! She struggled to look at her sister, Yun Lian to see what was going on. Yet, what she saw made her heart sink into her stomach. Yun Lian lowered her gaze as she said, “Sister, I’m sorry. My Brother-in-law and I truly love each other. I’ve been hiding this for so long now, and I can’t hide it any longer.”

One day, Katsuragi Daichi and his classmates found themselves in a different world. The god who summoned them to another world divided its power and gave it to them, saying that it wanted Daichi and the rest to defeat the Demon King as heroes. However, Daichi alone was given no abilities. And sure enough, Daichi was thrown away and used as a decoy in a demon’s den. Eaten by a demon, Daichi had lost consciousness and thought he had passed away, though when he came to he noticed his statuses had skyrocketed. He had obtained『Revenge of the Resented』. Every time he died, his abnormal ability powered up.

For the once dead Hua Yu Man, she has to do three things this lifetime: kill those who harmed her, kill the man who said he loved her, and protect a place called “home.”

She seems docile and gentle, with the air and temperament of a beautiful young lady. But in fact her heart is cold, overbearing, and black belly, with a mysterious identity that can drive the world crazy.

He is the Thirteenth Prince, but also the country’s disgrace; a cold and ruthless man who doesn’t put human lives in his eyes. But only towards a sometimes gentle, sometimes willful and sometimes disobedient woman, would this man be ceaselessly doting and spoiling.

Kieran was just an ordinary part-timer — a high school dropout who had also given up on boxing. With no parents and no real family, he survived by working his ass off every day. He was raised by a man he believed to be his father, but later discovered he wasn't — though the man passed away before the truth could fully sink in. What Kieran didn’t know was that he was actually the sole heir to a powerful business empire, the hidden son of a wealthy tycoon.
