Palace Intrigue with a Card-Based System

After spending sixteen years away from home, the Marquis's real daughter returned, only to be sent off as a consort to a tyrant who had slaughtered countless people less than a month later.

Ling Chu finally understood that in her parents' eyes, she was nothing but a sacrificial pawn meant to take the fall for the fake heiress.

Fortunately, she had a card-drawing System.

Congratulations, Host, you drew [The Mysterious Maiden's Youth-Preserving Art]!

Congratulations, Host, you drew [The Fox Immortal's Art of Seduction]!

Congratulations, Host, you drew [Yellow Emperor's Fertility Pill]!

Congratulations, Host, you drew [Taizong's Strategies for Governing the State]!

With the Fertility Pill and the Strategies for Governing the State in hand, Ling Chu was starting to get a little carried away.

Question: Should she kill the tyrant and take the throne now, or wait until she has a son, then kill the tyrant and put him on the throne?

The blurb is provisional. Historical romance.

Theme: Study hard.
