After the Evil Villain Was Reborn, the Hero's Party Was Left Heartbroken with Regret

Xie Nanchu is the Eighth Princess of Ningyuan. After three years as a hostage, she returns to find herself abandoned by everyone. Worse, on their wedding night, her beloved destroys her with a cup of poisoned wine.

After her revenge plans fail time and again over the next several years, she learns just before dying that she is the vicious antagonist in a story where everyone dotes on the heroine, and that this is the fate she deserves.

Reborn, she quietly goes mad: I want you all dead.

She expects to fight alone, but unexpectedly gets leverage over a "henchman."

Xie Nanchu: I know your secret. Help me, and I'll keep it hidden.

Use him, squeeze him dry, then kill him!

Mo Yanci appears to yield reluctantly, but in truth, he is the hunter lurking in the shadows, and she is his prey.

Only later does she learn that she isn't the only one who wants to overthrow the empire.

And she has already killed him once...
