The poison that Liu Jing had been poisoned with was soon discovered.

"Your Majesty, Miss Luo, I have found out that the poison that Lord Liu was poisoned with before his death was the poison of swallow grass. After consuming this poison, one will only feel uncomfortable, but it will not be fatal immediately. At least, it will take two hours for the poison to take effect. If there is strenuous exercise during the poisoning period, it will accelerate the onset of the poison."

Luo Xuening just frowned when she heard this. The poison would take effect in two hours. It was during this time that Gu Hang rushed to Liu's house and had a big fight with Liu Jin, which accelerated the onset of the poison for Liu Jing.

This is not a coincidence. We can only say that Gu Hang was used by someone, and the person behind him must be proficient in the poison of Yancao, and must know Liu Jing especially well.

"Prince Jing, since you don't have much time left, let's go to Liu's house now."

Luo Xuening could guess that the poisoning was related to the people in Liu's house.

Lord Jing's eyebrows moved. He originally thought that this kind of woman was very clear and thoughtful in her analysis, but his deliberate provocation made him very unhappy. Does this woman really feel itchy if she doesn't provoke herself?

“Let’s go.”

Long Moxun rarely let Luo Xuening go, just because this woman was doing things for him.

…

Liu Mansion

The moment the servants opened the door, they saw Prince Jing, who looked like a devil in their eyes. They were so frightened that they paralyzed on the spot. After a long time, they knelt down in front of Prince Jin with a "thump".

A few timid ones even began to worry about their own lives. After all, the Prince Jing Liquid was famous for its murderous effect.

At this time, Luo Xuening had already put on coarse cloth clothes, dressed like a man, disguised as a servant, and followed behind Long Moxun.

With Long Moxun, the artificial refrigerator, around, outsiders naturally wouldn't notice the little man behind him.

Long Moxun lifted his feet and walked into Liu's mansion, with a layer of frost still on his face.

"I will be investigating a case here tonight. I will give you a quarter of an hour. All of you should get dressed and come out."

There is no room for negotiation for everyone, including servants and masters.

Yes, Prince Jing is Prince Jing. Even in the middle of the night, he woke people up and asked them to cooperate in the investigation, and he spoke so confidently.

The servants dared not delay and immediately contacted the masters of each courtyard. Within a quarter of an hour, all the people from the Liu Mansion appeared in front of Long Moxun.

"Are you all here?"

Long Moxun's deep eyes scanned the crowd one by one, and his cold voice frightened the butler so much that his hands trembled. He replied tremblingly, "My Lord, everyone is here."

Long Moxun snorted coldly and scanned everyone's bodies one by one, paying special attention to those who had their heads buried particularly low and looked particularly panicked.

"Tell me, where in the mansion is the poison of swallow grass?"

As soon as Long Moxun finished his cold words, he heard a faint gasp from the person kneeling in front of him.

"Lord Liu was poisoned by swallow grass before he died. This swallow grass poison can only be hidden in fresh swallow grass. Even if you don't admit it, I can find out. So, it's best for you to confess your guilt."

Long Moxun said this not to elicit a confession, his patience was limited, and he was giving the murderer time to confess.

The person who poisoned him was hiding among those people who were humble and obedient in front of him.

"It seems that Madam Liu from Baihuayuan raised some dwarf swallowtails for you. I wonder if it was Madam Liu..."

At this time, the servants were kneeling in a row in front of Long Moxun. It was so dark that no one could hear clearly who said these words, but every word was clearly heard by everyone.

Madam Liu raised her head under the gaze of the crowd, met Long Moxun's aloof gaze, lowered her head timidly, and said in a deep voice.

"Your Majesty, there are indeed a few dwarf swallow grasses in my yard, but they are only for viewing. I dare not harm anyone, let alone my husband."

Madam Liu had a soft voice. Although she lowered her head, the moment she raised her eyes, Luo Xue Ningzhi saw the surprise in her eyes.

If he is really a murderer, he can pretend to be calm when being accused like this, but when he is stressed, his expression cannot deceive anyone.

Psychologically speaking, a person will unintentionally raise their voice when telling a lie, but Mrs. Liu's voice was calm, and the tone in which she defended herself was extremely gentle, almost the same as her usual self.

Luo Xuening can conclude that Madam Liu is innocent, however, once she falls into Long Moxun's hands, he won't care whether she is wronged or not.

"Come here, search the yard. If it is true, take this person away."

Madam Liu opened her eyes wide, still with a hint of fear in them. She glanced around and saw the mocking smile of Madam Gu among the crowd.

Although Madam Liu is a co-wife, her status is very different. The Liu Mansion is the domain of the Gu family.

Soon, the servants pulled out some dwarf swallow grass from Madam Liu's yard. Long Moxun looked at the blue swallow grass and snorted coldly: "Take her away to me."

What Long Moxun cared about was not who poisoned Gu Hang, but who framed Gu Hang for Liu Jing's death. As for the methods of the woman in the backyard, he had no time to care.

This was to convict Madam Liu. Madam Liu clenched her hands and shook her head helplessly. She admitted defeat.

"Wait, Your Majesty, I think this poisoning has nothing to do with Madam Liu."

Luo Xue Ning spoke from behind Prince Jing. She was wearing coarse clothes, and her messy hair covered most of her face. She looked frail, but her bright eyes were sparkling and stunning.

Long Moxun turned around and looked at Luo Xuening. Was this woman trying to make trouble for him again? He had just clearly declared Madam Liu's crime, and she was so angry that she openly slapped herself in the face in front of everyone.

"Luoxue Ning, mind your own business."

Luo Xuening's mission is to clear General Gu's grievances, not to go against himself over these trivial matters.

Luo Xuening completely ignored Long Moxun's warning look. She walked straight forward and checked the swallowtail grass that she had pulled out from Madam Liu's yard.

This is a beautiful blue flower shaped like a swallow's tail. In modern times, people call it delphinium, a perennial herb of the genus Delphinium in the Ranunculaceae family. This flower is beautiful, but it is highly poisonous.

Among Liu Jing's stomach contents was oxalic acid left over from this plant, but this does not mean that Mrs. Liu was the one who poisoned Liu Jing.

"All the swallow grass is here?"

"Yes, in the Liu Mansion, there is only one in Madam Liu's yard."

The butler answered like this. Although he also had doubts about Luo Xuening, they did not dare to offend someone who could follow the prince and be a brave man against the prince.

"Did anything happen before Lord Liu was poisoned?"

It was still the butler who answered. He glanced at Madam Liu and then spoke in a calm voice.

"The old man drank the soup made by Madam Liu every day. Just before the old man passed away, Madam Liu brought the soup to the old man."

Luo Xue Ning frowned when she heard this. From what the housekeeper said, everyone would point to Madam Liu as the person who poisoned Liu Jing, but Luo Xue Ning was suspicious.

Being in a big house, Mrs. Liu couldn't be so stupid as to bring poisonous soup to Liu Jing to drink so that everyone in the mansion would testify for her.

This is undoubtedly a wrongful case.

Luo Xue Ning was about to speak when a deep voice rang in her ear: "Luo Xue Ning, I don't have time to deal with these trivial matters."

The voice was mixed with resentment. He had come to find Luo Xuening to prove Gu Hang's innocence, but she went to help someone who had nothing to do with him to prove his innocence.

Long Moxun's voice was very soft, only audible to the two of them, and Luo Xuening also lowered her voice.

"How can a matter involving human life be a trivial matter? Your Majesty, please be kind."

Long Moxun’s face turned pale. “…” He has grown up and no one has ever told him to be kind. Does Luo Xuening really not know that she is a demon who kills people without blinking an eye?

This woman is now teaching him a lesson. However, Lord Jing actually has the urge to learn from her.

Long Moxun clenched his palms, looked at the woman's serious expression, and finally agreed to her wishes.
