Jiang Pengji got something called the Court Intrigue Stream System.
System: “Your goal is to become the most prestigious woman in the kingdom (the Queen)!”
Jiang Pengji: “Okay, System. No problem!”
Years later, she met the target by becoming the most prestigious woman (the Empress).
Jiang Pengji: “Well done, no?”

The world has ended. I’m the only survivor left in the shelter. But by my side is the world’s most advanced AI, Artemis.

Hey! Yes, it’s you! Where are you going in such a hurry? Oh, I know, I know life is not easy, but do n’t try too hard.

You ask me what I am doing here? Haha, I just sit here and tell some old-fashioned stories about wizards, dragons … you know, those things that have appeared in our dreams.

Hey, guess what, if you are not so anxious, why not sit down and listen to them?

Although I think I am not a good storyteller, I can guarantee that this story is absolutely my heart!

Come listen, maybe, it can make you dream again, those that have long been forgotten by us … legend.
