"Miss Suxin said so, and the official asked." Meng Yan said, "Of course, if there are some questions that the girl doesn't want to answer and can't answer, she can also not say it, this is the girl's freedom." ”

"Su Xin understands!" Bai Suxin nodded.

"Miss Suxin, what symptoms did Mr. Ling Zunbai have when he was ill, such as nausea, abdominal pain, vomiting, etc."

"Yes, when my dad was sick, he was nauseous and vomiting, and he said that his stomach hurt, and the things he spit out had a strong smell of swill!"

"Are you sure that the vomit that Old Man Bai spat out has a smell of swill?" Meng Yan asked.

"I'm sure, I remember this very clearly, it was the first time I found out that my father was sick, when he vomited all over his body, and the taste of swill is still fresh in my memory." Bai Su said in his heart.

"Also, what are the other symptoms besides the smell of swill in the vomit?" Meng Yan asked.

"There are other symptoms, let me think about ......"

"By the way, when my father was seriously ill, his limbs twitched, and there was blood in his stool." Bai Su said in his heart.

"Blood in the stool?" Meng Yan nodded, another important feature of chronic arsenic poisoning.

"Miss Suxin, tell the official in detail about every day when Ling Zun is seriously ill."

"Good!" Bai Suxin nodded solemnly.

……

As Bai Suxin narrated, Meng Yan learned more about Bai Xinyuan's situation when he was seriously ill, and he became more and more inclined to his own judgment that Bai Xinyuan did die of chronic arsenic poisoning.

But how the arsenic in his body got in, it's hard to say, after all, this man has been dead for three years.

"My lord, that's all Su Xin knows, do you have anything else to ask?"

"No, Miss Suxin has already said in great detail." Meng Yan Road. "But this official still has a question, that is, who is in charge of Ling Zun's diet at ordinary times?"

"Normally, it's Suxin, and sometimes I ask Xi'er to help, but my father's favorite thing is to cook by himself." Bai Su said in his heart.

"What about Bai Jiao's?"

"Dad rarely eats what she cooks, and she rarely cooks, even when she comes home to eat. That's all made by the cooks at home. ”

"Does your father have any special preferences?" Meng Yan asked.

"Smoke dry tobacco!"

"Smoking dry tobacco." Meng Yan frowned, the history of drought and tobacco is not long, and legend has it that South America passed through the Philippines to the coast of Fujian in Taiwan, and then spread.

It should be in the Wanli period of the Ming Dynasty, but it was more than a hundred years later, why is it now?

"Adults haven't seen it, it's just a long bamboo pole, hollowed out inside, and then a cigarette holder is installed. Place the sun-dried tobacco on top of it, then light it and smoke it on the other end! Bai Suxin explained metaphorically.

This thing is not popular, there are not many people in the capital who have this hobby, and this tobacco is not cheap, it is all imported from Nanyang.

"When did Ling Zun's hobby start?"

"After Shaoqing was born." Bai Su thought for a moment and said.

"How did you come here, does Miss Suxin still have an impression?"

"It seems to have something to do with that woman. For a while, my dad was in a bad mood and didn't have good spirits. The woman gave this thing to her father, and then taught him to smoke dry tobacco......" Bai Suxin said in surprise as if she remembered something.

"I need Ling Zun's dry tobacco stick, and is there any dry tobacco that Ling Zun smoked?"

"The cigarette stick was dirty with my father, the woman said. Dad liked to smoke dry tobacco before his death, and the cigarette stick was his beloved thing, so he simply buried it! Bai Suxin said.

"What about the dry tobacco?"

"I guess it's gone, it's been a few years, who still keeps that thing. It is estimated that it was also buried. ”

Meng Yan sighed slightly, the tobacco leaves may not be found, but the tobacco stick is still there, but now he doesn't know if he can detect the arsenic residue from the cigarette stick.

If the person who administers the drug is very small, there is very little residue, and even if the arsenic residue is detected on the cigarette stick by liquid soaking, it cannot be used as evidence.

Because the rotting corpse of the cigarette stick is soaked together, and there is arsenic residue in the rotting liquid of the corpse, how can the cigarette stick not have it?

Meng Yan quickly returned to the next room.

"Ge Tong, when you checked the coffin, did you find such a long pole, which is made of beads, and there is a head in front of it, which is made of copper?"

"There seems to be such a thing, my lord, what are you asking for?"

"Do you know what this thing does?" Meng Yan Road.

"I don't know, I've never seen it before, I guess it's some kind of plaything." Although Ge Tong has seen a lot, he has never seen this cigarette stick.

Meng Yan also knew that this thing had not yet become popular, and smoking dry tobacco was a later thing, but Bai Xinyuan's ability to play so well was probably related to the fact that he used to be an errand in the palace.

What the common people have never seen, the royal family has not seen it, this Bai Jiao clan is also quite capable, and he can actually find such a way to make Bai Xinyuan addicted.

"What about things, take a look at it."

"Here, my lord, do you think this is it?"

Ge Tong handed over a long stick-like object, which was rusty, heavy at one end and light at the other, and Meng Yan took it.

It was a cigarette stick, Meng Yan took it in his hand and looked at it, and recognized that this was a cigarette stick.

"It's this thing, I'm afraid Old Man Bai's death is inseparable from this thing." Meng Yan sighed.

"My lord, are you saying that this thing killed Old Man Bai?" Ge Tong was surprised, such a long bamboo pole can kill people?

"To be exact, someone used this thing to poison Old Man Bai, but at present, this is just the official's speculation, whether it is the truth or not, this is unknown." Meng Yan Road.

"My lord, how do you prove it?"

"The easiest way to prove this is to find something that goes with it." Meng Yan Road.

"What's that?"

"This official will explain to you this, this thing is a tool used to smoke tobacco, this tobacco is not owned by my Ming Dynasty, but from overseas, it grows in the coastal area of Fujian, so this tobacco leaf is very valuable, it can also be regarded as a medicinal herb, it has a refreshing effect, and can also prevent pests, however, his toxicity is stronger than the medicinal properties, people who smoke for a long time are easy to be addicted, and it will be extremely dangerous to the body!" Meng Yan explained.

There are two sides to everything, it depends on how to use it, tobacco is not completely without benefits, it is a raw material for medicine and light industry, but it is one of the killers of human health.

Of course, the people who are dangerous to tobacco are still a long time after it became popular, and people now do not know how dangerous they are, because it is a kind of harm that accumulates over time, and it will not be discovered until a long time is discovered, but once it is discovered, it is already too late.

Although smoking is addictive, it is different from drugs, once the drug is infected, it is difficult to quit, tobacco is different, if you want to quit, it is still very easy.

"My lord, this smoking tobacco is similar to smoking Wushisan, right?" Ge Tong asked.

"There is still a difference, smoking tobacco will make people excited at most, but it will not produce hallucinations, unless you smoke a lot of tobacco, and Wushisan is a drug, smoking this kind of thing seems to be physically and mentally pleasurable, but it will form a strong dependence, and the end result is death!" Meng Yan said, "Smoking tobacco does not necessarily lead to death, but it will be dangerous to health, and how dangerous it will be depends on the individual's situation." ”

"I understand, then this tobacco is not a deadly poison, why is Old Man Bai poisoned?"

"The old man Bai is the poison of arsenic, this tobacco is not the poison of arsenic, but if someone quietly mixes arsenic into the tobacco, that person will be poisoned after inhaling!" Meng Yan explained, "Little by little, little at a time, it adds up, and after a certain amount, it will be poisoned to death, and the deceased does not know that he was poisoned, and even after being poisoned, it will be considered a violent illness and die!" ”

"My lord, this is such a powerful killing method!" Ge Tong exclaimed.

"This is just the official's inference, in fact, to kill people like this, and they are also good at calculating, once the amount of arsenic is hit, and the person who is killed suddenly dies, it is easy to be self-defeating." Meng Yan nodded.

"What your lord said is, so what now?" Ge Tong also heard that this matter was a bit tricky, although there was no case, but a natural death incident turned into a poisoning murder case, which was completely different in nature.

"Ge Tong, this matter is a favor from this official in private, and even if the real culprit is found, the bitter master will not pursue it, all he wants is a result."

"Why, beating people, doesn't the plain girl want to find the murderer for the old man?"

"The murderer is not difficult to find, but it is difficult to prove that she did it, in fact, everyone can count it in their hearts."

"What do you mean?"

"The official didn't say anything, don't guess, okay, it's not early, finish the work early, and the official invites everyone to eat roast whole sheep in the evening!" Meng Yan Road.

"Really, sir?"

"The training base of the Patrol Division is in my father's house, and we will all stay there tonight, and listen to the arrangements of the official." Meng Yan said with a smile.

"Great, I thought we were going to live in Yizhuang!"

"Yizhuang is a place where people live, not to mention girls, they are not bolder than our old men." Meng Yan said with a smile.

"My lord is really pitiful!"

"Ge Tong, remember what the official said, a good woman is used to hurt." Meng Yan was very serious about Ge Dao.

Ge Tong was stunned for a moment, and then a blushing and ashamed look appeared on his face, he knew that he beat his mother-in-law as soon as he was drunk and let Meng Yan know, he was persuading him how difficult it was to marry an obedient daughter-in-law.

What's more, she also gave birth to such a well-behaved, obedient and exciting son to him.

"My lord, remember the lowly position, and the lowly position will never beat the daughter-in-law again!"

"Hey, hey......" (To be continued......
