The Disabled Emperor's Uncle's Substitute Poisonous Concubine

In her previous life, Lu Yao trusted her eldest sister and married the powerful but disabled Prince Ning on her behalf. In the end, she was hung on the city wall and shot through the heart with an arrow. Prince Ning, who was poisoned by her, took his last breath and avenged her bloodbath in the palace. Before she was reborn as a substitute, she vowed to trample under her feet those who had bullied her in this life. Her abusive stepmother? Be a concubine! Killed her sister-in-law? Disfigured! As for Prince Ning, who was implicated by her, he should be a well-behaved and virtuous housekeeper~~ Relying on his superb poison-making skills, the two of them would work together to level up and fight monsters. He handed her a knife when she tricked someone, and supported her when she got into trouble. In the end, Princess Baiqiehei poisoned the prince to death due to slippery hands. Prince Ning's face was full of doting: It doesn't matter, I'll carry it. Tell the emperor to change the crown prince. My princess just lacks the queen's phoenix crown~~
