[Ancient times + quick time travel + the heroine is not a virgin + giving birth + system cheating]
It's just a cheating ordinary person fighting in an ordinary harem! There is no complex palace battle plot that needs to be pondered over and over again and burns the brain! (At least not in the early stage, because the author doesn't know how to write)
It took Xu Yu seven years to climb to the position of marketing director. Now she has traveled to ancient times and wants to compete with a group of young people for favor? Okay, what Xu Yu has is the strength and means. What's more, she also has an artificial retardation, ah no, artificial intelligence (system) help. She wants power, status, and a lifetime of glory and wealth.
Note: The heroine is not a good person, she knows how to pretend, hehe.
