Bo Ruoyou looked at the cook, "How often do you pour your water into it? How did it pour it?"

When the cook heard Bo Ruoyou's questioning, he felt uneasy on his face. "Often, there will be people who collect water every morning, so we will go out through the back door and fall down. However, we are not many people, and sometimes we will forget it in the morning."

"How many times have you turned upside down in the past two days?" Bo Ruoyou asked while looking at the bucket. At this moment, the bucket was filled with half a bucket of kitchen waste. The water was mixed, and the sour smell was even more pungent.

"It's been reversed three or five times these days, but it's only reversed yesterday morning."

The cook answered carefully, and Bo Ruoyou couldn't help but frown. These wild cats ran in to find food, but the bucket here was turned upside down several times. Why would the cat die?

She asked the servant to come over torch, and went to see the cat's body without feeling the stinking. The cat's corpse had been frozen for a long time, but there was no obvious sensation. It seemed that it was dead within today. The two cats' fur were dirty, there were no obvious blood on their mouths and noses, and there were no obvious scars on their bodies. It was difficult to judge how they died for a while.

But at this time, Bo Ruoyou saw a pile of broken porcelain pieces piled up next to the bucket illuminated by the torch. The pile of broken porcelain pieces could be vaguely seen from cups, bowls, plates, etc. Because it had been piled up for a long time, not only did mold spots and mosses grow, but also many food and sewage spilled from the buckets condense on it. It was quite disgusting when you look closely.

But Bo Ruoyou's eyes were fixed on it, because she found that the top of the pile of broken porcelain pieces was slightly far from the bucket, and the white porcelain was pressed. The white porcelain was exactly the same as the cups she used to drink tea in the lobby just now. She was almost sure that this was the same model.

Although there are many stains on the broken porcelain under the pile of porcelain, the top few white porcelains are very new. Apart from some dust, there are almost no mold spots and water dirt. Thanks to the excellent weather these days, in addition to the porcelain pieces of the teacup, there is also a broken porcelain bowl that seems to have just been thrown here in the past few days.

Bo Ruoyou asked the cook, "Don't you clean up these broken porcelain pieces?"

The cook hurriedly said, "Although these things are broken, they are reluctant to throw them away casually. These piles have been piled up for more than half a year."

Ceramics are rare and expensive for poor and poor families, and all the tea shops here can be considered high-quality, so it is reasonable to be reluctant to throw them away. Bo Ruoyou picked up a piece of white porcelain from the ground and asked the servant who had been following him: "Look, are you using this cup specially for Biluochun?"

The servant stepped forward and looked carefully, nodded, "Miss has such a good eye, it is used to make Biluochun."

"Then think about it carefully. When Lord Song came that day, he used the same cup? Did that cup break that day?"

Bo Ruoyou's voice was gentle, and there was no such force as the servants. The servant said without thinking: "I do use the same cup. What kind of tea in our tea shop has a fixed number, and it will not be changed casually. Lord Song ordered tea that day, and drank it alone for a while before he went to the backyard. When he left, we went to the private room to collect his tea set. It was also sent by the villain to the kitchen. But the villain did not know how to break it. When the villain brought it, the teapot and tea cup were still in good condition." After he said that, he turned around and asked the chef, "Aunt Zhang, do you know when this cup was broken?"

The cook came forward and looked carefully for a while, then his eyes lit up slightly, "It was Agui broken, it seemed to be broken seven days ago. She was deducted half a month's salary for this." She was neat and said, and turned around and walked towards the front yard. Soon, she brought a little girl over.

The girl was fifteen or sixteen years old, with a pale face and thin skin, especially her hands had many wrinkles. It was caused by long-term soaking water. The cook said, "It was her who broke it. She was the one who washed dishes here. She also cleaned the ordinary teacup. This teacup was expensive. She broke one that day and cried for a long time after being scolded."

A Gui was quite nervous and looked at Bo Ruoyou carefully, as if he was afraid of being scolded again. Bo Ruoyou's voice slowed down a little, so she approached and asked, "Look at this cup that you broke? If so, do you remember the situation that day?"

A Gui looked a little relaxed, "I broke it, just seven days ago, after noon, I was dozing off and reacted a little slower. As soon as it was delivered to my hand, an unstable cup slid to the ground. The white porcelain was thinner and it broke in response."

It was the afternoon seven days ago when Song Yu came to the tea shop.

The answer seemed to be getting closer and closer to her suspiciously, and she asked again: "In addition to this teacup, is there a teapot?"

Agui said: "Yes, there is still half a pot of tea soup in the teapot. I was scolded at that time and felt very uncomfortable. I was too lazy to go far, so I poured the tea soup into the flowerbed next to the well behind and washed the teapot clean."

Bo Ruoyou frowned and asked her to lead the way to the well. Agui led her around for a while. Bo Ruoyou suddenly saw a low well on the well platform. The ground next to the well was paved with bluestone slabs. At this moment, a large wooden barrel was placed aside.

Agui said: "The cups, bowls and plates on weekdays are cleaned by the well. I poured tea soup on that day, and it was poured there-"

She pointed to a small flower bed under the backyard wall not far away. It was a gardenia. Now the branches and leaves are green, the buds are swaying, and the sweet fragrance of flowers floated quietly. She walked up to her and went to see it. Sure enough, she saw the tea that had already dried up in one place. She pointed to that place, "Did you splash the tea here earlier?"

Agui nodded quickly, "It's there. I am abiding by the rules on weekdays and I don't dare to mess around with tea and kitchen waste by the well. But I regretted it that day, so I poured it nearby."

The whole tea shop needs to be used in this well, and it is indeed quite advisable on weekdays, but Bo Ruoyou is very glad that Agui poured the tea soup here. She never expected that after these seven days, she could still find the leftover tea that Song Yu drank that day.

She asked the servant to help find the utensils, put the already shriveled tea leaves together with the next piece of soil, and looked at the tea leaves carefully. Although the tea smell was no longer fragrant and the color changed drastically, she could still tell that it was the shape of Biluochun. When she returned, she asked the servant again, "When Lord Song came, did anyone else order Biluochun in your tea shop?"

The servant shook his head quickly, "It was not long after noon. There were not many people coming to have tea and have fun. Except for Lord Song, there seemed to be only one or two tables of tea guests, and no one ordered the best Biluochun."

Bo Ruoyou was sure in his heart. In this way, he could be sure that the remaining tea poured into the flower garden and the broken white porcelain on the ground were exactly what Song Yu used that day!

When he arrived next to the water bucket, Bo Ruoyou carefully picked out the pieces of the teacup and the pieces of the porcelain bowl, and then looked at the yard with some difficulty.

After a moment Bo Ruoyou asked the cook, "Does there be mice in your kitchen?"

The servant said that there were rats and cotton bugs in the warehouse, and when the cook heard this, he immediately nodded, "Yes, we are trying to catch mice every day!"

Bo Ruoyou's lips curled slightly, "Then please help me, catch a few mice, and I'm going to live." She looked at the attendants of the Marquis's mansion and asked them to help together.

Although everyone was puzzled, her status was extraordinary at first glance. The attendants of the Marquis' Mansion did not dare to disobey them, so the cooks naturally agreed. Several attendants followed the cooks to the front yard to catch mice. Bo Ruoyou asked Agui to help him get a few big bowls and get water.

She put the porcelain pieces in two bowls, then filled the dry tea and soil in the flowerbed with one bowl, and poured water into them. The porcelain pieces were also covered with a lot of dust and dirt. When the water poured in, it quickly became turbid. Bo Ruoyou didn't mind, and then carefully cleaned his hands. Just as she was busy, a group of people came over at the entrance of the kitchen yard. Bo Ruoyou raised his eyes and saw that Huo Weilou was bringing people.

Huo Weilou waited for her to disappear in the lobby for a long time, and then asked someone to come back to check it out. When he learned that a cat corpse was found in the yard, he came over immediately.

“What is this doing?”

Huo Weilou walked to Bo Ruoyou and saw two large bowls in front of her containing turbid water. He subconsciously wanted to reach out, but Bo Ruoyou stopped him anxiously, "Don't move, it may be poisonous."

Huo Weilou frowned immediately, and Bo Ruoyou pointed to the corner of the wall in the distance, "The corpse of a wild cat was found there, not far from the kitchen bucket. Their buckets were turned upside down several times, but I found white porcelain fragments on the pile of porcelain pieces next to the bucket. When I asked, it turned out to be the cup used by Lord Song on the day he came. The teapot used by Lord Song was cleaned, but the remaining tea soup that day was splashed into the flowerbed by the person in charge of washing dishes, and I dug up the soil together."

Huo Weilou looked at her and listened to her very seriously. She continued: "In addition to the porcelain pieces of the cup and the soil that has been soaked in tea, there is also a big bowl here that is broken. Judging from the dirty appearance, it seems that it has been thrown over the past two days. I also picked up the porcelain pieces and poured them into water. No matter which one is poisonous, you can try it out. Ordinary cats steal food and like to sniff and lick it. If you lick the poisonous porcelain pieces, it will be not uncommon to die of poisonousness."

As she said that, she pointed to the buckets and the backyard wall. "It may be that the buckets are poisonous, or they were poisoned after eating some poison from outside, but the possibility is not high. Try my guess first."

Huo Weilou frowned, "How to try?"

After asking this, he found that there were a lot fewer attendants. Bo Ruoyou blinked and said, "Try it with a mouse."

Huo Weilou raised his eyebrows. At this time, several servants walked out with a bamboo cage, "Mr. Marquis, girl, have you caught five, is it enough?"

Bo Ruoyou nodded and looked into the bamboo cage. Sure enough, she saw a few big rats three or five inches long. Although she was not afraid of the corpse, she still felt a little creepy when she looked at these filthy living things. Huo Weilou saw it and stood beside her and asked, "Feed the rats water?"

Bo Ruoyou felt it was difficult to feed water, so he turned around and said to the cook, "Can there be porridge here?"

The cook should have it, turned around and found half a bowl. Bo Ruoyou mixed with water to eat rice, and found many cages to separate the mice, and then put the mixed and divided meals into them. The mice immediately started eating as they smelled the smell.

Huo Weilou stood in front of the cage, Bo Ruoyou couldn't help getting closer to him and said softly: "Although it has not rained these days, I don't know that there are poisons left on it. If I can't try it out, then this method will not help."

She looked up at Huo Weilou again, "What did the Marquis say when he saw Master Wei San?"

Huo Weilou had a lot of solemn eyes, "He said that Song Yu did come to the teahouse that day. They went to the backyard, but he just wanted to send some good tea to Song Yu and asked him to choose, but later there was no one Song Yu liked, so Song Yu left."

It's so simple? Bo Ruoyou frowned and then fell into the bamboo cage containing mice. "There was no other evidence that day, and now there is no way to prove whether what he said is true or false."

Huo Weilou frowned, "That's true, but I have asked him to take him back to the prison."

Bo Ruoyou was a little surprised, and turned around and saw a bit of cold and solemn look between Huo Weilou's eyebrows and eyes. She knew that Huo Weilou was calm when he came, but she had already thought about leaving no room for anything. However, this third master Wei was the brother of Wei Shu. Wei Shu would probably be reluctant this time. If there was a golden ointment here, it was related to Song Yu's death, what role did Wei Shu play in it?

She thought for a while but didn't ask. She was sure that Huo Weilou had a plan in her mind.

"If you can find out that the cup is poisonous, it will be considered a proof."

Bo Ruo's voice was filled with hope, and he stared at the bamboo cage again. However, the rats were almost finished eating after the meal. He didn't see any abnormalities in the mouse. She frowned, "The mouse is small and should die more easily than the wild cat. Am I guessing it wrong? Especially the soil in these flowerbeds, which has not rained, and the poison should be on the soil."

She muttered to herself that because Huo Weilou was coming, the others had already pushed it even further, and she didn't dare to interfere easily at this time. Waiting was always harsh. The night was dark and the surrounding bustling lights seemed to be dimmed by two points. She looked at Huo Weilou with worries, "Marty, I'm afraid I guessed it wrong."

Seeing her a little annoyed, Huo Weilou's eyes were trembling, "It's okay to not find the poison. After all, after so many days, I carefully looked up the other servants in the tea shop and confirmed that Song Yu arrived in the store after half of noon. In this way, he walked here from Sanqing Temple and happened to meet him. In addition, what you have obtained in the restaurant opposite is enough to prove that this is where he was poisoned."

It is enough to capture people based on this point alone. As for whether some evidence can be found, it is a direct method of entrustment.

Bo Ruoyou sighed in his heart and looked into the bamboo cage again, but saw the rats inside it still ran around in the cage. She was completely disappointed. Huo Weilou glanced at the sky, "It's too late, I'll send you home first, you don't have to worry about other things."

Wei Quan was taken away, and that's all she could do. She nodded in dismay, thinking to herself that if the tea that Song Yu drank outside was not poisonous, then it must have been poisoned after Song Yu and Wei Quan entered the backyard. However, no one was present at that time, and it was impossible to know if Song Yu had eaten and drunk anything after entering the backyard.

Bo Ruoyou followed Huo Weilou out of the yard. Seeing her lowering her eyes and silent, Huo Weilou couldn't help holding her hand. Bo Ruoyou felt that this was inappropriate, but Huo Weilou just held her palm and let go. He said, "Even if there is no iron evidence, it's a lot to interrogate Wei Quan. At most, you can get it clearly in just three or two days."

Bo Ruoyou couldn't help looking at him, "What if Master Wei San was a person with a particularly firm will?"

Huo Weilou looked at her puzzled look and felt that her understanding of Zhirusi was not accurate enough, but he was unwilling to tell her about this, but said, "If you are a person, you have weaknesses. No matter how strong a person is, you have weaknesses. Just prescribe the right medicine."

Bo Ruoyou looked at Huo Weilou with thoughts. In her eyes, Huo Weilou was a person with no weaknesses, and a person with strong will and unshakable. She pressed this thought in her heart and did not say it out loud. Just as the two were about to enter the lobby, someone suddenly chased her on the path behind her.

"Marty, girl, a mouse has fallen to the ground with poisonous hair!"

The two stopped at the same time and turned back to see the attendant of the Marquis's Mansion who was left behind to chase him out. Bo Ruoyou hurriedly asked, "Is there a rat poisonous hair?"

The attendant nodded, and the light of Bo Ruoyou's eyes suddenly shone brightly. She turned her eyes to Huo Weilou, "Marquis—"

Huo Weilou raised his lips, "You guessed it is right, go back and take a look."

Bo Ruoyou responded and almost trotted back the same way. She was so happy that she could not do anything like this!

When she returned to the kitchen yard, she saw several cooks gathered next to the cage and looked at it. She didn't expect that Bo Ruoyou's strange behavior would be really poisoned by her. Bo Ruoyou marked each cage. She thought that this time, it must be two mice that were poisoned together, and the big bowl must be non-toxic.

She saw the cage that was trying the big bowl at the first glance. Sure enough, she felt sure of the mouse inside, and looked back. When she saw that the light in her eyes was dim and her eyebrows were frowning.

In the other two cages, only one mouse was tilted on the ground and the other mouse was also rustling. Not only that, Bo Ruoyou fell into hesitation after seeing the marks above clearly.

Huo Weilou had wide shoulders and long legs, and he was not behind her. So he watched her face change a few times and couldn't help but step forward and ask, "What's wrong?"

Bo Ruoyou looked carefully for a few moments, straightened up and said, "It's a little different from what I guess. It's OK to be non-toxic on the big bowl, but if it's poisoned, these two other mice should be poisoned, or, one is seriously poisoned and the other is slightly poisoned, but now it's the opposite of what I think."

Huo Weilou stared at him, and he understood Bo Ruoyou's meaning, "You guessed that the mouse who had tried to pour tea soup and soil was poisoned the fastest, but now the one who was poisoned was the one who had tried tea cup?"

Bo Ruoyou nodded, "Half of the tea pot is in the soil, which is most toxic. However, there is only a thin layer of tea pot on the tea cup. After it is broken, it is thrown in the corner. Even if it is toxic, there should be only some residue."

After she said that, she went to see the mouse cage again, but saw the one that was tilted on the ground seemed to have died, while the other two were also jumping around.

Bo Ruo's eyes were slightly dark, "The person who poisoned him is poisoned in the cup."

This is the only explanation, but Bo Ruoyou looked at Huo Weilou, "But arsenic is white powder. Although the tea cup is white porcelain, it is too obvious to put poison into the cup. Song Yu cannot not find it. Could it be that the servant did the trick when pouring tea?"

Huo Weilou's narrow eyes, "When Song Yu was still drinking tea, he said he wanted to see Wei Quan. Wei Quan came out to see him first, and then the two left to the backyard together. The situation was unknown at that time, but in addition to the servant, there was Wei Quan also with Song Yu!"

The ordinary servant and Song Yu have no grudges and no grudges, and it is impossible to kill people casually. The only suspicion is Wei Quan. Bo Ruoyou thought about it and felt that it made sense, "Indeed, if the poison is put into the teapot, the servants will be afraid of something wrong when picking it up. But if it is just in the teacup, the teacup will be cleaned, and it can be considered silent to everyone in the store."

She felt that this made sense, and she made a certain decision in her heart, so she made this inference. After all, she found the poison. Bo Ruoyou was no longer as heavy as a moment ago, and there was a sense of relaxation and pleasure between her eyebrows and eyes. She was afraid that something might happen, so she waited for a while. In the end, she was sure that only the teacup was poisonous. When it was almost time to come, Huo Weilou took her to the front yard.

Because of the discovery of poisonous substances, although Wei Quan was the most suspected, the others were somewhat unable to remove them. The shopkeeper who was waiting outside first saw Huo Weilou arresting Wei Quan without saying a word, and then heard that a highly poisonous substance was found in the backyard, and immediately shouted for justice.

"Mr. Marquis, how could we poison the imperial officials? No matter whether it is the boss or the servants, we dare not. This is the place where we rely on for our living. Even if we want to harm anyone, we will not be able to harm here."

The shopkeeper knelt down and begged hard. Huo Weilou ordered others to continue searching and taking the people, and he wanted to send Bo Ruoyou home first. He ignored the shopkeeper. When the two of them left the door, he saw the shopkeeper chasing him again. As soon as he walked to the door, he was stopped. So he said bitterly: "Mr. Marquis Mingjian, we really did not poison. The poison must have been brought to frame us by someone else!"

On the carriage, Bo Ruoyou was moved when he heard the shopkeeper's crying roar, and frowned and remembered. Huo Weilou saw her expression and said, "Don't think about what he said, the poison has been detected, and any quibbling is futile."

The carriage moved, but the shopkeeper's roar was still endless. Bo Ruoyou asked, "Are they all going to the prison?"

Huo Weilou nodded, "When entering the Jingzhao Yin Yamen, everyone must prove it and then pass the court. It is not ruled out that if someone knows it, or if he is an accomplice, he must interrogate it carefully."

The dead person was a fourth-rank court official, and he was very involved. Of course, no one would let Huo Weilou go casually, but for some reason, the shopkeeper's crying lingered in Bo Ruoyou's mind, "Marty, I'm also thinking now, why do they want to poison Lord Song in a tea shop? Lord Song is a nobleman, and is familiar with the Wei family. In the public eye, how dare they attack him in their own place..."

"Don't follow his words." Huo Weilou held her hand and stopped her from thinking. "What is the truth? Just let the officer continue to ask. You don't have to think that they won't do this. The stupidity and arrogance of the powerful will sometimes exceed your imagination. And no one knows what Song Yu came here for that day. What did the two of them say? Perhaps it was Song Yu doing something that caused Wei Quan to take action. Isn't it more convenient to be in his own place when he was anxious? The poison did not occur on the spot. He only had to argue to the end, and there was no way he could do it."
