Cute? the Little Junior Sister Killed the Immortal Lord with the Sword and Went Crazy

The modern killer Yao Yao traveled to the world of immortality during his mission and became a little baby. Thinking that he would get a golden finger by traveling through time, Yao Yao was full of expectations. It turns out that her golden finger is actually a system passed through by a boss! No ability at all, but lots of words! "Can you give me a little more spiritual stone this time?" "No, you're a part-time worker and you still want a raise?" The boss exploded: My dignified CEO was forced to lay off. I wash your clothes, cook, clean up your storage bags that are as messy as a garbage dump every day, and help you with your work. Doesn't this deserve a salary increase? Yao Yao sheathed her sword: "Last time I washed my clothes and made three holes. Last time I cooked and marinated the fish with vinegar, it's better not to do it." Boss Ba:...... Yao Yao has no big ambitions, he just wants to practice hard and return to his original world as soon as possible. But she was betrayed by her best friend, and her senior sister, who was both a teacher and mother, was killed by her best friend in front of her! In order to take revenge, Yao Yao decided not to return home at all. She wanted to kill the best friend that the Immortal Lord pretended to be! Boss Ba:? Sister, didn't we agree that we should be trash together? You can help me ascend.
