As soon as Bai Qiurui looked up, she saw Shen Yuan sitting on a chair. A pair of dark eyes stared directly at the unfinished refreshments in his hand, looking like he suddenly realized.

"My lord? But what comes to mind? ”

Bai Hong looked at Shen Yuan and saw that he had been looking at the bean paste dumplings made by Bai Qiurui, and then seemed to think of something, and suddenly had an epiphany.

"Lord Shen, could it be ......"

Bai Qiurui saw that the two of them had the same expression, and couldn't help but secretly hook the corners of her mouth.

It seems that both my father and Shen Yuan have thought of the key to the matter.

"There are some things that we have to wait for the scene to decide."

Shen Yuan Huo Ran got up and walked towards the door as he spoke. Seeing this, Bai Hong immediately followed, and opened his mouth with a happy face.

"My lord, the lower official will go with you."

Shen Yuan nodded, the two of them were about to cross the door, how could Bai Qiurui let go of this opportunity, and immediately spoke.

"Daddy, Lord Shen, slow down."

Seeing the two of them turn around, Bai Qiurui begged: "Daddy, my daughter wants to ask her father's permission to go together." ”

Bai Qiurui has her own plans, if she wants to change her tragic end, she must come out of a new plot, and she must not always follow the plot trend in the book.

However, Bai Qiurui, as the daughter of Shaoqing of Dali Temple, is a beautiful girl, how can she go out at will if she wants to?

After Bai Hong's initial surprise, he naturally refused without thinking about it.

"No, how can you go out and show your face when you have a daughter's family?"

Bai Hong looked at this daughter that he had neglected for a long time, and when he remembered his ignorance for so many years, he unconsciously felt some pity in his heart.

He glanced at Shen Yuan beside him, and then said, "What's more, Daddy and Lord Shen have business to do, not to go out to play." This is the scene of the murder, and it is inconvenient for you to watch from the sidelines. ”

Bai Qiurui knew that her father would talk about her identity as a woman, but she was also prepared.

"Daddy also said earlier that it was a dish made by his daughter that made you figure out the key to the case."

Bai Qiurui looked at Bai Hong, and glanced at the refreshments on the table next to her: "Fang Cai, Daddy and Lord Shen, didn't it also because of that refreshment that they thought of the key point of the case?" ”

Bai Hong paused, and Shen Yuan on the side glanced at the snacks sent by Bai Qiurui, and looked at her without a trace.

In the end, before Bai Hong was about to speak, he unexpectedly agreed: "If the white girl wants to go, it's okay." ”

As soon as these words came out, Bai Qiurui was a little surprised, and even more surprised was Bai Hong.

In addition to the fact that Bai Qiurui is a young daughter, it is inconvenient for her family to go to this murder scene, but Bai Hong is indeed because Shen Yuan is by her side.

is also an official in the court, but Shen Yuan became the secretary of the criminal department at a young age, and in terms of position, he is still above himself.

Now that Shen Yuan has spoken, Bai Hong can't say anything more. He glanced at Bai Qiurui a little helplessly, and finally had to warn him repeatedly.

"Well, don't make a loud noise when you get to the place. If you're afraid, just stand on the sidelines, don't run around. ”

Bai Qiurui saw that her father was already chattering before he set off, knowing that he was for his own good, so he could only nod his head like pounding garlic and respond with his mouth.

Seeing this, Bai Hong was a little relieved, and smiled apologetically at Shen Yuan. In the end, the three of them left the house together.

Liu Yuanwai's mansion was not far from the mansion of Bai Hong, Shaoqing of Dali Temple, and after some discussion, the three decided to go on foot.

Bai Qiurui had never seen an ancient market, so she looked left and right curiously when she went out. The streets of ancient times are a different scene, but they are just as prosperous and lively. Rouge gouache, jewelry hairpins, pinched candy people, sugar gourds are all available.

Bai Qiurui, who was enjoying it, didn't pay attention to the look of her father beside her, she was only curious when she saw the ancient market for the first time. However, in the eyes of his father Bai Hong, he couldn't help but think that he had neglected him for so many years, and he had mixed feelings in his heart.

It wasn't until Bai Qiurui's rarity had passed, and when she came back to her senses, she found that her father and the abyss beside her didn't say a word, and their eyes fell on her intentionally or unintentionally.

Bai Qiurui was a little embarrassed at this time, and she coughed dryly twice: "Daddy, my daughter still doesn't know what case you and Lord Shen are working on." ”

In order not to let the two misinterpret the purpose of their trip, Bai Qiurui had no choice but to open her mouth to break the silent atmosphere.

This case was explained in the original book, and she was already familiar with this case in her heart, but on the surface, she still had to pretend that she didn't know.

Bai Hong was the first to glance at Shen Yuan, who was traveling with him, after all, when it came to business, he didn't dare to make his own decisions. Shen Yuan's official position is above him, and it is not his turn to make a decision whether to say it or not.

"This matter has long been rumored in the community, and it doesn't hurt to say that it is a white girl."

Shen Yuan glanced at Bai Qiurui, and then briefly explained the process of the case: "Three days ago, Liu Yuanwai reported the case in the county office, saying that his only son Liu Yaozong suddenly disappeared. There is no one in life, and no corpse in death. ”

After searching, he was finally found in a dry well in his house. When he was found, Liu Yaozong was already in a different place. ”

Bai Qiurui listened to Shen Yuan very carefully as she walked. At the same time, she was thinking back to the detailed description of the case in the original book.

Liu Yuanwai in Beijing has always been kind and charitable, and has no enemies. Liu Yaozong, an only son in middle age, has been in love since he was a child. Due to years of doting, the adult Liu Yaozong did not learn or know, drank flower wine, and soaked in the green building.

Even so, Liu Yuanwai is still spoiled. Until two years ago, Liu Yaozong married his wife He, and the couple had been arguing.

He didn't like Liu Yaozong to go out and fool around, but Liu Yaozong refused to change his teachings, and finally even beat He Shi. Going out to spend all day and drinking is getting more and more powerful, and there is no one for ten days and a half months.

This ultimately led to Liu Yaozong's wife He being unbearable. When Liu Yuan went out, he poisoned her husband, and then cut off his head and threw it into a dry well.

The three of them said as they walked that they had arrived at Liu Yuanwai's house. On both sides of the door are the guards of the Criminal Department, who are responsible for guarding the scene.

Shen Yuan said: "Liu Yaozong has no enemies on weekdays, he is generous when he goes out, and he has a group of friends who drink and meat. The only person who could have poisoned him was his wife, Ho. ”

Bai Qiurui said with a suddenly realized expression: "So, now Daddy and Lord Shen are investigating the method of poisoning the He family?" ”

"On that day, I asked all the people in the house, and searched all over the house, but found nothing. If it weren't for the refreshments you sent, we might have had to work a little harder. Bai Hong said with a smile.

The three of them entered the mansion, and did not find the dry well where Liu Yaozong's body was, but went straight to a pool specially opened up in the mansion for raising fish.

Ask the guards to fish out a fish and cut open the belly of the fish, which contains a large amount of golden grass. Needless to say, Bai Qiurui also knew that this was the golden silk grass that his father and Shen Yuan were talking about in the study.

It's just that this kind of grass white autumn stamen is the first time I have seen it. But she knew that this seemingly non-poisonous golden silk grass was the method He used to poison Liu Yaozong.

Golden silk grass is golden in color and non-toxic. It is a common aquatic plant that can be used to feed fish. However, He added mercury to the golden silk grass used to feed the fish, and when Liu Yuan went out and Liu Yaozong was rarely at home, he had people cook fish containing mercury.

Liu Yaozong has a habit of eating, he likes to drink warm wine, and the hotter the wine, the better. Mercury is catalyzed by hot wine, and the consequences can be imagined.

"Let the fish and the golden grass in the belly of the fish be examined."

Shen Yuan's gaze stared at the pool for a moment, and then asked the dissected fish to be examined.

Bai Qiurui looked at Shen Yuan's expression, as if she was pondering something. The dark eyes stared at the water, and the depth was unfathomable.

I don't know what's wrong, Bai Qiurui suddenly asked boldly, "What is Lord Shen thinking?" ”

This question can scare Bai Hong beside him a lot. When he saw that his daughter interrupted Shangshu's train of thought without knowing the severity of the matter, his brows jumped fiercely, and he was afraid that Shen Yuan would be displeased.

However, in fact he was overly concerned. Shen Yuan looked at the rejection of people for thousands of miles, but in fact, there were not many shelves.

Facing Bai Qiurui's inquiry, he said lightly: "Liu Yaozong's wife He is just a weak woman, if there is really something wrong with this fish, how can she come up with such an ingenious poisoning technique?" ”

Bai Qiurui answered: "What does Lord Shen mean, is she someone else to help?" ”

Shen Yuan didn't seem to expect Bai Qiurui's thinking to be extremely agile, and glanced at her with some surprise: "I don't rule out this possibility." ”

As he was talking, the guard who had left with the fish before walked briskly: "My lord, there is a new discovery. ”

Shen Yuan and Bai Hong were shocked, and the group immediately followed the guards to the side courtyard of Liu's Mansion.

The overall layout of Liu's Mansion is elegant, whether it is a pool for fish farming or a partial courtyard at the moment, it is a step by step, pleasing to the eye.

Bai Qiurui stood in the side courtyard, and saw a young man in a gray robe holding a silver needle in his hand, studying a fish on the stone table in front of him, which was the one that had been disemboweled.

"How?"

It was Shen Yuan who spoke, and Bai Qiurui saw that he seemed to know the man in gray, and the two spoke very naturally.

The man in gray raised his head and glanced over, his gaze stayed on Bai Qiurui for a moment, and then asked rhetorically, "How do you know that there is something wrong with the golden silk grass in the belly of this fish?" ”

Without waiting for Shen Yuan to speak, Bai Hong couldn't help but speak: "Please ask Gu Gongzi to say clearly, what's the problem with the golden silk grass in the belly of the fish?" ”

Bai Qiurui saw that Shen Yuan had not answered, and the man in gray was bored with himself, touched his nose and said, "The golden silk grass in the belly of this fish is mercury that cannot be measured by a silver needle. After the fish is eaten, the fish itself will also carry the poison of mercury. ”

Shen Yuan listened to Gu Gongzi's words and immediately began to deduce: "Fish with mercury, Liu Yaozong likes to drink hot wine the most......"

Bai Qiurui answered: Drinking alcohol can invigorate blood, and mercury accelerates catalysis in the body when it encounters heat, not to mention hot wine, which made Liu Gongzi poison to death. ”

"Not bad! This girl is exactly what she said! ”

The man in gray looked at Bai Qiurui appreciatively, with a smile on his handsome face: "If it was just the mercury in the fish itself, it wouldn't have caused Liu Yaozong to die immediately." It was the pot of hot wine that catalyzed the mercury. ”
