Han Daring took the phone, and the other party was Mei Ruohong.

Mei Ruohong Road:

"The petals you sent are what you had guessed! This is indeed a poison, and some of the symptoms of poisoning are similar to arsenic poisoning! ”

Han Da'er called Mei Ruohong before, just to ask him if there was any poison, the poisoning symptoms were similar to arsenic poisoning, but no arsenide residue could be detected. Mei Ruohong didn't think of similar poisons for a while, only said that there might be some plant toxins and similar symptoms.

So when Han Daring found these petals in the tea can, he instinctively felt that this was the kind of poisonous plant he was looking for, and now his conjecture was confirmed.

According to Ms. Mei, the petals that Ms. Han sent Ms. Zhang to the laboratory in Bath were poisonous plants called meadow saffron, also known as colchi.

It is a whole poisonous plant. Commonly found in moist meadows, it grows in woodlands of England and Wales and parts of Scotland, where cultivation was not yet introduced domestically.

After poisoning, there will be symptoms such as burning sensation in the throat, extreme thirst, difficulty swallowing, diarrhea, abdominal pain, cardiovascular collapse, and even hallucinations and coma. And some of its symptoms are similar to those of arsenic poisoning.

Then, Han Da'er asked Mei Ruohong in detail about the characteristics of this poison, the poisoning mechanism, and the test method.

Putting down the phone, when Han Dada'er was thinking about it, the phone rang again, and this time the call was from the epidemic prevention hospital.

After Ni Zhongkun's body was sent to the epidemic prevention hospital, Lao Su put down his work and took the lead in conducting an autopsy on Ni Zhongkun's body. As Han Daring speculated, Ni Zhongkun did not die of allergic reactions, but of poisoning.

Lao Su found that Ni Zhongkun's throat and tongue were a little swollen, and the air hole temporarily cut on the clavicle under the throat was accurately positioned to unblock the airway, but it was not fatal, but the corpse had some symptoms, which were somewhat similar to arsenic poisoning.

It stands to reason that if arsenic poisoning occurs during a meal, there will be redness and swelling of the stomach and intestines, and residual arsenic substances will be found. Since arsenic cannot be eliminated through the kidneys, it should remain in the body, but no arsenic residues have been detected in the intestines and stomach, and there are no residual arsenic substances in the blood, kidneys and liver.

In the case of arsenic poisoning, due to the destruction of red blood cells in the arteries, the skin of the deceased will be slightly yellow, but it will only be a little pale, and there will be no obvious change in skin color. It's just that the deceased seems to have blood in the urine and a high amount of urine protein in the bladder.

According to Lao Su's speculation, Ni Zhongkun probably died of some unknown plant toxin, but Lao Su had never seen this toxin, and it was likely to be some overseas plant toxin.

After hearing this, Han Da'er told Lao Su the relevant information about the poisonous colchicum that Mei Ruohong had just told him on the phone, and told Lao Su his speculation.

“…… If this poison is the case, is it possible based on what I just speculated? ”

Han Daring asked.

Lao Su said categorically:

"Absolutely! Wait a minute, I'll check it in detail as you said......"

After that, Lao Su put down the earpiece and came to Ni Zhongkun's corpse again, fortunately, the knife edge of the dissection had not been stitched up at this time, otherwise it would have to be disassembled one by one.

Han Daring waited quietly with the telephone receiver, feeling a little nervous in his heart.

After a long while, Lao Su's happy voice came from the phone receiver again:

"Sure enough! Same as you speculated! ”

Han Daring breathed a long sigh of relief and said:

"Even if it is confirmed, those blood organ samples still need to be sent for testing, and it is good to have a clear test report!"

"Of course! I've already arranged for that gluttonous fat guy to send the samples away! ”

Before Lao Su called Han Daring, he had already taken samples of the deceased's blood and organs and asked Fan Tong to send them for testing, but the government's laboratory department was procrastinating, and it was estimated that the test results would not be available in ten days and a half months.

In fact, at this moment, Han Da'er already had a clear understanding in his heart, even if there was no poison test report, with the discovery of Lao Su's autopsy, he was completely aware of the truth of the series of incidents that happened in the Meng family.

At this time, Zhang Biao, who took Bai Chongwei's car to the Pasteur laboratory, has also returned. However, as soon as he came back, he asked Han Da'er to arrange for other investigations and evidence collection, and asked him to go back to the main hall first, mobilize some people, and then collect evidence together.

Before Zhang Biao left, Han Dada'er also instructed him that he must be extremely confidential, and that he must block the news when he arrives at the place where he needs to search for evidence and investigate, and he must not let people report to the suspect, so that the suspect can be prepared!

Although Zhang Biao is tall and strong, has a beard and beard, and looks quite bluffing, he is actually the same as Fan Tong, he is also a lazy and deserted person. If other leaders were allowed to support him back and forth like this, he would definitely find an excuse to desert, but Han Daring was his savior, and Han Daring's arrangement should be a matter of no exception.

What's more, in order to collect evidence as soon as possible, Bai Chongwei asked his driver to send Zhang Biao to the main hall. There is no need to have legs back and forth, and there is a car seat, Zhang Biao doesn't feel any hardship, but is a little happy, but Bai Chongwei's driver Lao Zheng is miserable, driving back and forth.

Han Daring has figured out the basic truth, but there are still some speculations that need to be confirmed. So he walked to the third floor again, the old man Meng's study!

Walking to the door of the study, he stood quietly at the door for a while, listening carefully to the voices in the room. There was only the sound of the pages gently turning in the study, and there was no other sound.

The surroundings were very quiet, but if it weren't for Han Da'er's own deaf and clear-sighted eyes, he would not have heard any sound at all if he had changed to someone else, and through the door.

Han Daring knocked on the door politely, and heard Pei Run inside say:

"Come in!"

Then he pushed the door and walked into the study.

In the study, there are dishes on a small table after the meal. Pei Run is still sitting behind the desk drinking tea and reading. Han Daring looked around and saw that although the furniture and books in the room were still the same, he always felt that something was different.

"Old Man Meng! You must already know what happened at lunchtime! ”

Han Dadao said.

Pei Run still looked at the pages of the book, didn't even lift his eyelids, just nodded slightly.

Han Daring said:

"Old man Meng, please mourn!"

Pei Run sighed and said in an old voice:

"Hey! Maybe it's a good thing! In the past few years, Xiaoqiu has been obsessed, but now it is clean! ”

"Old Man Meng doesn't seem to like this second aunt!"

"Originally, Xiaoqiu liked it, so it was up to her.

…… It doesn't matter if you eat soft rice, but this kid is not the same, so I wanted to persuade Xiaoqiu to separate from him, but this kid was stunned by Ni Zhongkun's kid and couldn't listen to other people's words! ”

Between the words, it seems that Pei Run also knows Ni Zhongkun's character outside.

Regardless of the truth or falsity of Guang Peirun's identity, just the warmth of his old father who cherishes his daughter, and a trace of sadness about his daughter's marrying the wrong man, is not something that an ordinary child can pretend.

Han Daring said:

"I want to ask Old Man Meng, since you claim to be borrowing a corpse to resurrect your soul, do you remember the day you died? This is a bit abrupt, please forgive me! ”

Pei Run raised his head at this time, looked at Han Da'er, and said:

"What? Don't believe that I'm Meng Bangyan, and you still want to test me? It was the last night of my last life, and I certainly remember! ”

Han Da'er didn't care about his question, but asked again:

"How did you feel when you were sick? I mean the feeling of being unwell! ”

Pei Run had suspicion in his eyes and said:

"I suddenly felt sick at that time...... Later, my consciousness was more blurred, and I had diarrhea and stomach cramps...... Why do you suddenly ask about this? ”

Han Daring took two steps closer, looked into Pei Run's eyes and said:

"What if you weren't sick but poisoned?"

Pei Run's eyes widened and said:

"Of course I know what's going on with my body, who's gossiping?"

Han Daring said:

"This is not a random rumor, Old Man Meng was indeed poisoned and died that night, so I want to know how you felt when you were unwell that night?"

"Impossible! My family is full of my children, and I usually treat people very well, and besides, the official face has been confirmed......"

"What if it's Ni Zhongkun who poisoned it?"

Han Dadao said.

Pei Run's brows furrowed slightly, as if he was hesitating.

Han Da'er continued:

"You have been separating your second daughter from him, and you are not willing to pay for these two people again, what if he holds a grudge?"

"This ...... He should ...... Don't have the guts! ”

Pei Run's voice was a little hesitant, and he paused and said:

"Forget it, he's all dead now...... There's no point in worrying about it, and I'm back! I don't want to talk about these things anymore! ”

Han Daring said:

"Well, since you don't want to mention it again, then I'll ask something else! I would like to ask, did anything special happen to the Meng family eight years ago? ”

"Eight years ago...... Eight years ago it was all trivial, I don't remember exactly...... Oh! By the way, in the summer of eight years ago, my eldest daughter came home to borrow money from me, but I didn't borrow it, so I had a fight with my eldest daughter, and then I didn't move around for a long time, and it wasn't until the last few years that the relationship eased a bit! ”

Pei Run recalled.

Han Daring said:

"Nothing else?"

"What else do you think will happen?"

Han Daring said:

"Please forgive me for saying this, but now the brothers and sisters of the Meng family are actually still suspicious of your identity, to prove your identity and convince them, it is necessary to confirm a lot of past details, I hope you don't have to hide it, I am doing this to help you confirm your identity as soon as possible!"

And as you said, those were all things from your last life, and there is no need to hide them now! ”

Pei Rundao:

"Believe them or not, I have nothing to hide!"

Han Daring nodded and asked again:

"On the night you died, did your eldest daughter Meng Huaiyi come to bring you ginseng soup?"

Pei Run nodded and said:

"Not bad!"

Han Daring said:

"And what did you two talk about?"

"It's nothing, Huaiyi still wants to borrow money from me, I didn't want to borrow it, because he borrowed money to help the two little uncles fill the gambling bills. To tell the truth, Wen Qing has a good character, but he is a little doting on his two younger brothers, if the money is given to Huaiyi and Wen Qing, of course it is okay, but to pay off the gambling debts of Wen Qing's two younger brothers, of course I can't borrow money from this bottomless pit.

But in the end, Huaiyi cried and begged me, and my heart softened, so I could only promise to lend him a sum of money! ”

Han Daring listened, pondered slightly, and then asked some more about the past, and then said goodbye and left the study. This is already in his chest, just waiting for Zhang Biao to collect some of the last supporting evidence.

Just as Han Daring walked out of the study, his eyes swept over the bookcase, and he suddenly understood why he felt that the items in the study were still the same, but they seemed to be a little different......
