He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

“Second Master, Madam said that there is no money.”

“Hurry up and give her 200 million pocket money.”

“Second Master, Madam has been hidden by the brokerage company.”

“Buy the company and make her the boss.”

“Second Master, the doctor said that the child in Madam’s womb is not yours.”

“…Quack doctor! Get another doctor.”

In the previous life, Li Beibei was ruined by a scumbag and a bitch, and she was reborn with one trick, but she became the favorite of the top boss Fu Erye.

She abused the scum, the second master handed her a knife, she set fire, and the second master added firewood to her.

She turned the entertainment industry upside down, and the second master’s words “I’m used to it” made countless jealous people shudder. ——-Everyone in Yuncheng knows that the decisive and fearful Fu Erye has only one weakness. It was his little ancestor Li Beibei who had made a baby kiss with him. Even if her little ancestor wanted to ride on his head, he would bend down for fear that she would not be able to climb up.

Not only that, but in the eyes of outsiders, a man who is as perfect as a god is always rejected by his little ancestors, who think he is old, too rich, always step on the left foot first when entering the door, and even think that the moon on the roof of his house is not round enough.

Everyone couldn’t stand it anymore: “Second Master, your little ancestor is spoiled by you!”

Second Master Fu: “I am willing, who has any objections?” My little ancestor would have to get used to kneeling for a lifetime. ———I like you, serious and cowardly, from one end to the end——Fu Jingmo

- Description from novelbuddy

Katherine Zara, a single middle aged office worker, went about her day as she always had; wake up, go to work, come home and read or play games. However, today would be different. Before she left for work, her ex broke into her apartment and killed her.

When she woke up, she was given many choices. She could pick her new world, pick her starting point, and pick her system among many other things. And so Katherine decided to become a servant to a villainess.

Follow Katherine as she serves her petty, demanding mistress in a world of swords and magic.

Additional: The Female Lead (Katherine) will be submissive to her mistress, but will be cold towards others. I plan on having some action, but mainly this will be a story about Katherine serving her mistress and leveling up her system.
