Regressor In A Strange World - Chapter 8: The Conqueror!

Mimizuku, a small girl with chains on her wrists and ankles and the numbers “332” branded onto her forehead, wanders into the Forest of Night seeking to be eaten by a monster. However, when the ruler of the monsters, the mysterious and beautiful “King of Night,” refuses to eat her, she tries to formulate a way to convince him otherwise.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

In the group favorite article, Nan Qiao is a female supporting role who has been robbed of the heroine’s halo, and is cast aside by her father, three brothers, grandparents, and friends.

The father wants to break away from her, the three older brothers only dote on the step-sister, and the patriarchal grandparents also dote on the stepmother’s daughter.

The fiance said: “Don’t stalk me, the person I love is Zhizhi.”

Father: “Nan Qiao, can you stop messing around, your sister is your savior.”

Brother: “Nan Qiao, I’m so disappointed in you.”

Second brother: “You actually hit your sister with your own hands, don’t you know that my sister is weak and can’t stand it?”

Third brother: “I didn’t expect you to be so heartless.”

Grandpa and grandma: “Let her get out, our Nan family doesn’t have such unworthy descendants!”

After being reborn, Nan Qiao suddenly came to her senses. Since you all dislike me and abandon me, then this time I won’t let you all go.

He turned around and inherited his grandfather’s billions of property, and was doted on by his seven elder brothers.

The bossy brother, the top-ranking second brother, the professor’s third brother…the buddies are crazily competing for favor.

Just when Nan Qiao was doing well, he was targeted by the top villain BOSS in the original text.

Huo Yichen pinched Nan Qiao’s chin, narrowed his narrow and deep eyes slightly, his eyes were cold and tired, “Why, you want to run away without taking responsibility for teasing me?”

…

Just when Nan Qiao thought everything was over, her family members were reborn one after another and remembered the memories of her previous life just like her.

The family members who abused her thousands of times begged her to go home with red eyes and frenzied expressions.
