"You stupid guy, Ding Quan is not a murderer. Isn't this obvious?" Mrs. Dou patted Dou Lie's head angrily: "This guy is so scared that he is so scared that he has pissed off. Do you have the courage to kill someone?!"

Dou Lie thought, that's true!

He slapped his thigh, "I said Ding Quan is so timid. He has a ghost in his heart for a long time, and he is afraid that we will arrest him as a murderer because of stealing money, right?"

"No," Yun Xi immediately spoke, but his little hand secretly gave Mrs. Dou a thumbs up.

It must be Aunt Qing.

After such a mistake, it did not extinguish Dou Lie's enthusiasm for deciding the case.

"Ding Quan entered the room to steal things; Zhao Liu put down his cloak and left. How did the murderer poison it?" Dou Lie asked afterwards.

This is also the key point of the case: Only by figuring out how poisoning was done can the suspect be locked in.

"Although the poison was half a quarter of an hour after the body was found, the poison was not necessarily the one that was dropped within that half a quarter of an hour."

Yun Xi pondered for a moment and continued: "The murderer doesn't even have to poison himself. As long as he applies the poison to the one that Madam Wen will definitely touch, and there are enough food and food items."

Everyone in the room was silent.

It seems like a simple poison case, but it is quite difficult to catch the real murderer.

"I have already mastered a lot of clues, but why do I still feel like I have no idea how to start!" Dou Lie slapped his thigh with some anger.

"Let's start with the origin of the poison first." Lu Qingfan begs Dou Lie to open the archives warehouse and check everyone's origins.

"Okay, let Butler Jiang take you there." Dou Lie waved his hand and responded.

However, Lu Qingfan politely refused to ask Butler Jiang to intervene in and help, saying that he could just have the Leng brothers.

Yun Xi walked to the table and wrote a prescription and handed it to Lu Qingfan: "Sir, this is the medicinal materials needed to make 'Duize Wan'. After dawn, you can inquire at the pharmacy in the city."

It cannot be ruled out that the murderer himself will make Duizawa Maple.

"Okay." Lu Qingfan took the prescription and folded it solemnly put it into his sleeve.

There is no matter whether Yun Xi is the master or servant for the time being. She and Qingguo go back with Mrs. Dou and her party to rest. Lu Qingfan and the Leng brothers went to the archives to check the origins of the servants in the city lord's mansion.

On the other hand, Butler Jiang did not relax his vigilance to the servants who had entered and exited Madam Wen yesterday. He stopped their errands and asked them to gather in a yard, waiting for Lu Qingfan to summon him at any time.

Master Yunxi was settled by Mrs. Dou in Yanshui Pavilion next to the main courtyard, and it was only half a cup of tea to get there.

"You have been busy all day long and have been doing the work of Madam Wen again. You must be very tired. Let's go and rest. If you have any problems, it will not be too late to talk about it tomorrow."

Mrs. Dou comforted her warm voice, holding Yun Xi's arm with a tender voice, and she couldn't bear to let go for a long time.

Yun Xi also whispered to comfort her: "Thank you for your hard work for Aunt Qing...Madam Wen has a spirit in the sky, so she must not want Aunt Qing to be so sad."

Mrs. Dou's eyes turned red again, "You're saying it." She turned around quickly, raised her hand to stop Yun Xi from seeing him off, and hurriedly walked away with the maid.

Master Yunxi watched Mrs. Dou leave the yard before returning to the house.

"Madam Wen is so pitiful. You can see the lady if you hold on for a while." Qing Guo sighed while washing her face: "This thief is so hateful!"

Yun Xi said "yes", holding her chin and staring at the candlelight in a daze.

"...Miss, Miss?" Qingguo's hand shook in front of Yun Xi's eyes and asked in a low voice: "What are you thinking about? Ignore people for a long time."

"I was wondering what method can show the toxicity of 'Duze Pill'." Yun Xi said, looking at Qingguo: "The snacks and poisons left by Madam Wen's stomach are mixed together, and I can't tell the difference at all."

Qingguo was also distressed when she heard this, and the master and servant sat at the table and sighed.

"Forget it, go to bed."

Yun Xi pulled the little maid and lay on the bed. She was obviously tired, but she was not very sleepy. She fell asleep in a daze.

Let’s talk about Mrs. Dou’s sleep for half a night after returning to the house. She kept turning over like a pancake on the bed, which made Dou Lie unable to sleep well.

He sighed and hugged his wife in his arms: "You are too heavy, don't worry, the murderer will definitely not be able to escape from Echeng."

In the darkness, Dou Lie's eyes surged a little cold.

"I'm afraid." Mrs. Dou put her head in Dou Lie's arms and rubbed it softly, "As soon as Madam Wen dies, I'm afraid someone will attack Yun Xi."

"Don't worry, I've ordered the secret guards to surround her yard... And Lu Qingfan, his personal guard who is good at using swords, is also hiding in the dark."

Not to mention the murderer, even a fly is hard to fly in!

Mrs. Dou was surprised when she heard this, Lu Qingfan sent someone too?

"He is willing."

"Well, his future wife, isn't it supposed to be careful?" Dou Lie groaned and muttered in a low voice: "Can you sleep peacefully now?"

Mrs. Dou's lips finally had a smile, and she slapped her husband with a angrily sound, and finally got to sleep with peace of mind.

Lu Qingfan and Leng Hai are not that relaxed.

Lu Qingfan gave the prescription to the secret guards to investigate and came to the towering city lord's mansion archive.

Leng Hai looked up at so many archive bookcases, and couldn't help but smack his lips: "Tsk tsk, sir, should we just check this generation, or look up for three generations?"

If we check who has the Northern Mang bloodline in the third generation, hey, I guess we can't finish it in my life. We can live in Echeng and not leave.

"Talking too much, working."

Lu Qingfan's dark eyes were calm, and he began to sift through the corruption case of Jiangnan School Government and the time when Madam Wen entered the City Lord's Mansion in the past year, he had been to the Beimang people who came to the City Lord's Mansion in the past year.

The next day, the sky was bright and Yun Xi and his son woke up from their dream.

Qingguo, who was originally playing with a small heart, was startled by her own lady and looked at her in horror.

The master and servant looked at each other, and Yun Xi said excitedly: "I understand."

"Miss, do you know who the murderer is?" Qingguo immediately lost all sleepiness, and her black eyes were very bright.

"I know how to detect poison!" Yun Xi said, then immediately put on his clothes and ran out of the door with his shoes.

Qingguo didn't care about being hungry and shouted anxiously: "Miss, wait for Qingguo!"

Master Yunxi asked where Madam Wen’s kitchen where she usually eats, and then went there.

At this moment, Mrs. Dou, who had only woken up after only two hours of sleep, wanted to come to Yunxi's yard early in the morning and wait for her to get up for dinner.

Unexpectedly, before Mrs. Dou and her personal maid Xiang Ning could reach the gate of the yard, she saw Yun Xi's long hair scattered with waterfalls and heading towards the kitchen with her little maid.

Mrs. Dou pursed her lips and did not call anyone, but chose to keep up with Xiang Ning quietly.

"Madam, don't we call Miss Yun?" Xiang Ning looked at her wife with a worried look: "Miss Yun is in a hurry. What are you going to do?"
