Luo Xue Ning pointed with her little hand at the maid behind Madam Liu, the same maid who was called over by Madam Liu to bring out the remaining medicine residue.

Luo Xue Ning had been observing her for a long time. When this maid saw that Madam Liu was wrongly accused, what was revealed in her eyes was not worry, but contempt and complacency.

Following the direction of Luo Xuening's finger, Madam Liu also turned around and looked at her maid in surprise.

Just now, Luo Xue Ning had come forward to clear her name. Now, she trusted Luo Xue Ning very much and couldn't help but look at her maid with more scrutiny.

"Madam, no, I didn't. How dare I harm you?"

The maid's voice was a little sharp. She didn't dare to look at Luo Xuening. She just pulled Madam Liu hard. Her face showed an expression of great aggrievedness, but her pale fingertips revealed her guilt at the moment.

Luo Xuening shook her head indifferently, her clear eyes clearly saw through everything. Such little tricks in front of her were really not enough for her.

However, Luo Xuening did not expose the truth. She believed that this maid was just an official and the real murderer was hiding among these people.

"No, I remember that before the old man got into trouble, it was you who kept urging me to deliver the medicine. You were very abnormal. Tell me, do you have anything to do with this incident?"

Fortunately, Liu was not stupid. She could choose not to fight for it, but she could not be bullied for nothing. With just a little thought, she could notice that the maid was different.

Luo Xuening nodded slightly. She admired people who were good at using their brains.

The maid's face turned pale and her head turned involuntarily, but she suddenly realized something.

After being stunned for a second, she said loudly: "Madam, I have served you for so long, how can you wrongly accuse me in order to clear yourself of suspicion? I really didn't do it."

The maid screamed very loudly, and even angrily shook off Madam Liu's sleeves. She looked very angry, as if she was the scapegoat that Madam Liu was looking for.

Luo Xuening chuckled. If a person is really angry, he or she will talk loudly and move his or her hands at the same time. This maid suddenly spoke loudly just to cover up her guilty conscience, and the movement of her hands was just a deliberate cover-up.

Very good, the people of Nanshao Kingdom are all good actors, even a maid has such superb acting skills.

"Don't pretend. You kept pulling at Madam Liu's clothes because you were scared and wanted to find someone to rely on. Madam Liu, who has always treated you well, is a good candidate."

"But when you heard Madam Liu's questioning, you immediately pretended to be angry and even pushed her away, because in your subconscious, you did not regard her as your master, and you did not respect her. It was only a matter of time for a servant like you to betray your master."

The maid's face turned even paler. All her worries were actually said by a stranger. She looked at Luo Xuening with some fear.

He gritted his teeth and glanced in the direction of Luo Xue Ning. Generally, people who are ordered around by others will always subconsciously seek help from their masters.

The maid's intentional or unintentional glance actually provided Luo Xuening with the opportunity to guess the person behind the scenes.

However, there were too many people at the scene, and Luo Xuening could not judge who the murderer was based on the maid's eyes.

The eldest lady, Madam Gu, who had been standing quietly aside and had remained silent, glanced at Luo Xuening with disgust, raised her eyes, and winked at the housekeeper.

The housekeeper would come to his senses and immediately excuse the maid in an official tone.

"Sir, you said that it was this maid who poisoned the master, but these are just your own guesses. We need evidence to make a judgment. Can you show us the evidence?"

The butler spoke politely on the surface, but his eyes revealed disdain.

It's no wonder. Now two days and two nights have passed since Liu Jing was murdered. They have already cleaned up the evidence. What are they afraid of investigating the case?

Luo Xue Ning guessed this, and she did not intend to start from the evidence that the other party had already laid out, because what she found out in that way would definitely not be the truth. Luo Xue Ning had two years of criminal investigation experience, and her approach to solving cases was different from that of others.

"If you want evidence, it's very simple. You can look at the hand of the maid."

Everyone who heard this gasped, but Luo Xue Ning didn't care. She just said lightly, "Delphinium is a very special plant. It can be used as both medicine and poison. The delphinium that just appeared in the dregs of the medicine has withered for less than a day. It can be said that someone deliberately put it in the dregs of the medicine."

Even if Luo Xue Ning didn't say this, others would be able to guess it. Next, Luo Xue Ning was going to give her analysis.

"Just now, when I saw all the swallow grass being pulled out, Madam Liu looked heartbroken, which was enough to show that she was a person who loved to protect flowers and plants. In this yard, I didn't see anyone who specialized in taking care of flowers and plants, so Madam Liu's flowers and plants must be taken care of by her close servants, and you are one of them. You also have the best chance to put the swallow grass flowers into the medicinal residue and use it to frame Madam Liu."

"But, you also said that I am the one with the best chance, right? Madam Liu has more than one personal maid."

The maid who was accused by Luo Xue Ning finally said something unwillingly. Luo Xue Ning snorted. She actually quite liked being questioned by the criminal, because it would make her more rigorous when thinking about the evidence.

"As far as I know, a maid like you in a courtyard doesn't have to do rough work, but your right hand has been rubbed into fine strands. On the other hand, the skin on your body shows that you often take care of flowers and plants. The hands of other maids are all delicate."

"Moreover, the position you are standing in is closer to Madam Liu, which means that among these maids, Madam Liu trusts you the most. Apart from you, you not only have the opportunity to pick the swallow grass to frame Madam Liu, but also have the opportunity to poison the soup that Madam Liu brews."

Luo Xuening said there was a chance, not absolute, because these were just her speculations and the evidence was still behind.

At this moment, the maidservant was obviously unable to bear it. A thin layer of sweat had already appeared on her forehead, but she still forced herself to speak.

"No, this soup was made by Madam herself and brought to me personally. You accuse me of poisoning, but there is no evidence at all."

This was the maid's last act of stubbornness. When they planned this, they had already erased all the evidence.

What's more, the old man has been dead for several days. As long as she doesn't admit it, no one can find any evidence.

So, at this moment, the maid told herself not to panic. However, her slightly trembling hands revealed her uncertainty at the moment.

"No, I have evidence."

Luo Xue Ning interrupted the maid's words with a cold voice. She glanced at the maid's left hand with cold eyes and spoke lightly as always.

"Before you produce your evidence, let me analyze how you poisoned and killed Mr. Liu."
