Lan Ziye thought about it and nodded.

The head of the Zhu family was very reluctant to try the eldest lady of the Zhu family, but they could not go any further. The key was to convict the eldest lady of the Zhu family first.

Lan Ziye looked up at Chu Xixuan who was sitting in the main seat. She had to admit that Chu Xixuan's coming was necessary, otherwise she would have to fight at the Zhu family to see Madam Zhu today.

Soon, Madam Zhu, wearing a dark red embroidered cheongsam, walked in slowly with her head held high and chest puffed out. She had no sense of being a criminal at all and was still the noble and elegant Madam of the Zhu family.

"We have found evidence proving that you killed Zhu Fei!" Lan Ziye took the initiative and spoke straight to the point.

"Bluebird!" Chu Xixuan followed with a cold command.

After receiving the order, Qingniao took out the receipt and handed it to Chu Xixuan, saying, "The witness is in a hotel near the Zhu Mansion. You can call him over anytime if needed!"

Chu Xixuan handed the receipt to the Zhu family patriarch beside him and said, "This is the receipt for Madam Zhu's purchase of poison. It has Madam Zhu's signature on it!"

Before the patriarch of the Zhu family stretched out his hand to take the receipt, Madam Zhu snatched the receipt from Chu Xixuan's hand, glanced at it, smiled contemptuously and said, "It's just a receipt, what can it prove?" After that, she handed it to the patriarch of the Zhu family lightly.

The head of the Zhu family took the receipt very embarrassedly.

"The poison you bought is the Cixin poison, and Zhu Fei was poisoned by it. The Cixin poison must be taken continuously for a month before the poison will take effect and cause death. And a month before Zhu Fei's death, Zhu Fei was living with the eldest lady, eating and living with her. Doesn't this explain the problem?" Lan Ziye said coldly.

Hearing this, the head of the Zhu family had not yet reacted, but Mrs. Zhu laughed softly.

After laughing, she looked up at Lan Ziye and said, "Yes, I killed Zhu Fei. She should have died with her short-lived mother fifteen years ago. I raised her for so many years, giving her wealth and glory. What else could she not be satisfied with?"

"The eldest lady is so hard-hearted that she can kill a child she has raised for fifteen years!" Lan Ziye said sarcastically.

"Whatever you say! Okay, now I admit that I killed Zhu Fei. What do you think we should do? Lock me up like Zhu Ning?" Madam Zhu said indifferently.

"Why did you kill Zhu Fei?" Zhu Ning couldn't bear it any longer and asked with a choked voice, "When Zhu Fei and I were together, she never said a bad word about you! For fifteen years, people pointed at her and said she was an illegitimate daughter, but she never blamed you. She even said you were her benefactor and that without you, she wouldn't have had a good life. Why did you kill her?" Zhu Ning's eyes filled with tears as he continued, "If you didn't like her, you could have just asked her to stay away from you. Why did you kill her?"

Mrs. Zhu's eyes were dazed for a moment, and then she sneered, "Her mother stole my husband, and she stole the father's love that belonged to my daughter. Do I still have to be nice to her?"

"Then why do you still want to keep her by your side? Zhu Fei told me that your cousin once proposed to adopt her and give her the status of a legitimate daughter. Why didn't you agree?" Zhu Ning said.

Madam Zhu sneered, "You're really an ungrateful person who can't be tamed. You still want to be someone else's daughter!"

"When Zhu Fei talked to me that day, she wasn't sad, but happy. She said that you couldn't bear to part with her, and that you had a sharp tongue but a soft heart, and actually loved her very much!" Zhu Ning said.
