Where there is light there shall be darkness

Hero? Nahh I'm the demon.

In a world where the demons are looked on as the incarnation of evil, the human-demon war raged on across the whole continent.

The Seraphims, protector of humanity, and the Demon lords who rule across all demonkind. Amidst all the chaos, Simon was reincarnated as the lowest ranking demon noble.

A brutal world where the strong feeds on the weak, eat or be eaten, kill or be killed. A demon far off from humanity….a dream unfulfilled in his previous life will be achieved in this life. Taking on the moniker of Laplace, he destroys all his enemies and rise over them.

Just after retiring, Gu Xiyan was entangled by King Qin again.

King Qin looked down on Gu Xiyan, but he was greedy for her body and planned to take her as a concubine.

Gu Xiyan had a smile on her face, MMP in her heart. Becoming a concubine to an ex? It’s a joke, isn’t it good to make money?

I don’t want the peach blossoms to bloom, the second son of Yongcheng Hou and the third son of Qi Anbo all fall in love with her.

Zhou Mu, with [long legs], [buttocks] and [unbelievable appearance], was even more simple and rude, and went straight to the door to ask for marriage.

On the day Qin Wang got married, Gu Xiyan also got married in a grand manner.

On this day, there were not a lot of guests in Prince Qin’s Mansion, all the dignitaries in the city went to Zhou Mansion for a wedding, and the emperor condescended to officiate the wedding ceremony for Zhou Mu and Gu Xiyan.

Everyone knows that Zhou Mu is the emperor’s eldest son raised among the people.

Later, Zhou Mu became the emperor, and Gu Xiyan became the queen just by lying flat.

*

Zhou Mu is a man of unrivaled beauty, unique in the world, attracting the hearts of all the girls in the city, but he doesn’t understand amorous feelings, what love is.

Gu Xiyan, who was reborn and returned, knew that Zhou Mu was a non-marriage advocate, and never dared to have unreasonable thoughts about him.

Unexpectedly, on the day when she met with the third son of Qi Anbo, the noble and self-respecting man suddenly went berserk in the street, dragged her into the carriage, and asked her to marry him with red eyes: “My girl’s reputation has been ruined by me, so she can only marry me!”
