[Fictional setting, pure palace intrigue, no romance, having children and raising kids, my son must be the crown prince, career-driven, and realistically minded]

Warning: Not a story about a clean break, I don't love the male lead, there are angst and heartbreak, and the male lead is a scumbag.

Song Yuyan was addicted to a palace intrigue game where she cultivated her harem, but when she opened her eyes, she found herself transported to ancient times.

After three years of biding her time, she entered the palace as the legitimate daughter of a high-ranking official, her goal being to win the emperor's favor, bear a son, seize the crown prince's position, and ascend to the pinnacle of power!

The Emperor? He's nothing more than a tool for producing children!

As for those imperial concubines...

Anyone who dares to lay a hand on her will be eliminated, saving you all trouble!
