The night before the wedding, Lu Anran ate the poison peach cake arranged by Liu Mingyu as plotted, and she vomited blood that night. Lingxi and Dong qing teamed up to identify that Lu Xinran took the opportunity to plant the poison, and Mrs. Lu also pointed out that the Guanyin statue that Liu Mingyu had given to her contained poison and made her stay in bed for three years. Dong qing brought the Guanyin statue to confront Liu Mingyu on the spot. Everything was pushed to Cuigu, and Liu Mingyu also repeatedly explained that Cuigu was proficient in pharmacology. Naturally, she hid the Achyranthes in the Avalokitesvara statue. Dan Qing smashed and injured the fake Guanyin statue and exposed Liu Mingyu's conspiracy. Liu Mingyu let it slip what the poison was and Dan Qing said she never said what the poison was. She busted out accidentally that she was the one who set the poison.
Lu Qingzhou punished Liu Mingyu with fifty hits with a stick, forcing her to tell what poison she had given to Lu Anran, but Liu Mingyu wanted Lu Anran killed to pave the way for her daughter Lu Xinran, so she refused to tell them. Lu Qingzhou ordered the servants to not invite a doctor for Liu Mingyu, and let her die.
Lu Qingzhou invited doctors from all over Sucheng to diagnose and treat Lu Anran, and Lu Xinran appeared in front of Lu Qingzhou dressed as a bride, stating that the Lu family could only marry her off, and that Princess Qing could only be her. For the safety of the Lu family, Lu Qingzhou had no choice but to agree, and in order not to let outsiders know that the bride had changed, Lingxi was forced to accompany Lu Xinran to cover up for her. Before leaving, Lu Xinran threatened Lu Qingzhou with her identity as Princess Qing wife of Mu Ze to go find a doctor to treat her mother Liu Mingyu, otherwise she will take revenge for her mom in the future.
Liu Mingyu was still complacent in the room, thinking that their mother and daughter's plan was successful. Lu Anran came to tell her that she is still very much alive and she had already replaced the poison in Taosu. She told her that they fought with her life all her life but only to get Liu Mingyu killed in the end. Even if Lu Xinran married into Prince Qing's mansion, how could Mu Ze keep a useless person alive, and she is the one holding the Pisces Token and the Lu family's trump card. Seeing that her dream came to nothing, Liu Mingyu had no way to live on and she died.
King Qing's mansion was in a festive atmosphere, and King Qing Mu Ze was also toasting with the guests. Mu Ze call Mu Chuan to help him drink wine and toast his guest for him. The Fourth Highness, King Yi, came to celebrate Mu Ze's wedding and deliberately bought stinky dead shrimps and fish to the disgust King Qing. Fortunately, Mu Chuan and Mu Ze were quick-witted, and they satirized King Yi in a few words, making each him angry.
Mu Ze came to the wedding room and felt incredible to see the serious bride sitting in the room. The subsequent series of actions also made Mu Ze realize that something was wrong, and finally found out that the bride turned out to be Lu Xinran. Lu Xinran said that Lu Anran had passed away, and what Lu Anran could do for King Qing, she could too. But Mu Ze didn't like being set up by Lu family. What he wanted was the Lu family and Lu Anran. For today's matter, Mu Ze can let her go for the face of the Lu family, but if Lu Xinran can't be the head of the Lu family, he naturally doesn't mind having another wife who died young.
Mu Chuan was originally sad that his beloved married his second brother Mu Ze, but unexpectedly saw that Lingxi was going to commit suicide. After stopping her, he asked to know that Lu Anran had passed away, and Lingxi acted with Lu Xinran in order to protect the Lu family. Now that the play is over, she wants to go and accompany Lu Anran. Mu Chuan rushed back to Su City overnight, swearing that if Lu Anran was really killed, he would definitely avenge her.
