Liu Qingsong held his forehead, in case it was really poisoned, this matter would be unclear again!

"How can we determine what kind of poison 'drug' it is?" He Sizheng temporarily put aside distractions and devoted his attention to the case, for him, there was nothing more important than solving the case.

"Based on the state of the corpse, I suspect that the murderer killed with aconitum head. Because of the death caused by taking aconitum, there were no special signs in the autopsy, and the signs of suffocation were more obvious in general. It can't be found out at all, so Aconitum can be described as a necessary 'medicine' for killing. Ran Yan replied.

Liu Qingsong wiped the sweat from his sideburns, "Good 'medicine' is necessary...... Are you kidding? ”

Ran Yan said lightly, "What I said is the truth. ”

"So, as long as you are poisoned by aconite, you can't find out the cause of death?" He Sizheng asked unwillingly.

"Not really." Ran Yan stretched out his hand and gently pressed between the corpse's 'chest' and abdomen, "If you are lucky, if you cut open the abdominal cavity, you may find the aconitum 'medicine' residue in the stomach, and the mucous membrane and serous membrane may bleed a little." However, the residual toxic 'nature' of aconitum is very easy to be destroyed by putrefactive gas, and if it is not dissected in time, the poisonous 'nature' cannot be detected at all. ”

Under such conditions in Datang, even if the dissection may not be able to detect the toxic 'nature' of aconite, even if Ran Yan can 'get' anhydrous ethanol and all the things used to test the toxic 'nature', it is in vain for Datang to understand the test report. And the so-called use of silver needles to test for poison is not to detect all the poisons, itself depends on luck.

"He Sizheng might as well start with the clues on Dou Siniang's body, such as this handprint. Personally, I don't think it's possible that this size is a 'female' 'sex'. According to Dou Siniang's personal 'waiting' maid and 'medicine', she has been with Dou Siniang all the time, but only after Dou Siniang's face was a little strange, she went to the 'door' to call the little maid to ask for a bowl of summer soup. Half of Ran Yan's face was covered by a mask, and her voice was a little buzzing, and when she saw He Sizheng's head, she continued, "If you scrutinize her confession, she said, she got up and asked the little maid for a cup of soup to cool off, and when she returned, she saw that the lady's face was bleeding, He Sizheng might as well ask the little maid to confirm how long the period of time that Peony 'Medicine' left was enough for someone to break in and attack Dou Siniang." ”

"So, Mrs. Duanliang doesn't have any suspicions?" He Sizheng had just recovered from the shock of the autopsy and looked at Ran Yan inquiringly.

Ran Yan knew that it was impossible for Dali Temple to let her dissect Dou Siniang's body, so she took off her gloves and threw them into the box, and when she heard He Sizheng's words, she replied, "Can you allow me to ask He Sizheng a few questions?" ”

He Sizheng nodded and said, " Can. ”

"Solving the case lies in the motive, mastering the motive for the murder is equivalent to locking the murderer, I don't know what He Sizheng thinks Mrs. Duanliang's motive is for murder?" Ran Yan looked directly at him.

He Sizheng can also be regarded as holding the right to live and kill, and he has been beheaded many times, but at this moment, he feels a kind of pressure on Ran Yan, "This······ Further investigation is needed. ”

"What about the human and physical evidence?" Seeing that the official next to him was about to open his mouth to answer, Ran Yan chuckled, "The human witness can't be a peony 'medicine', right?" The physical evidence is the bag of cleansing flour? That peony 'medicine' is more suspicious than anyone else, wouldn't it be ridiculous and generous to let her be a witness? As for the cleansing flour, I still don't know what kind of poison is mixed in it, but Dou Siniang was suffocated to death, if it is not covered to death, it is the internal use of poison 'medicine', I don't know if the clean flour can cover people, or someone will take it internally? ”

A sharp remark made the three officials of Dali Temple speechless, if Ran Yan didn't say it at this time, they wouldn't have thought of it, but just a lady who figured out the clue in a short time, which really made them a little embarrassed.

"Good!" Liu Qingsong stroked his palm and found that everyone's eyes were focused on him, so he immediately changed his words, "Good analysis!" ”

Ran Yan packed up the toolbox, and He Sizheng immediately waved his hand to the jailer to help carry it.

"Thank you." Ran Yan Chong He Temple is bowing slightly. She knew that in fact, He Sizheng had already seen her identity, but she didn't know for what reason, she didn't even debunk it, and she was not angry at her sharp words, she should be thanked.

He Sizheng smiled faintly, "You're welcome." After that, Liu Qingsong and Ran Yan were led out of the morgue.

He Sizheng came out later, stood on the porch of the "door" of the "door" of the outer song, looked at the carriage in the distance, sighed, and complained that he could not control the sorrow of the angry Chang'an, but he was a strange "girl".

"He Sizheng, I have to report this matter immediately, one step ahead." Behind He Sizheng, a middle-aged man in a green 'colored' official uniform arched his hand.

"Zhang Yushi, please." He Temple is arching his hand.

Zhang Yushi's official position is actually to supervise the imperial history, not the person of Dali Temple.

The Imperial History Observatory is divided into three courts, one is the Taiwan Academy, which is mainly in charge of correcting hundreds of bureaucrats and pushing the prison; the second is the palace, with neat hands and guards; The third is the procuratorate, which is in charge of inspecting hundreds of bureaucrats, patrolling counties and counties, correcting prisons, purging the court, supervising prisoners, and so on.

The official rank of the imperial history of the Taiwan Academy is the highest, followed by the palace, and the lowest grade of the procuratorate, but the management of things is complicated and extensive, and there is also the right to impeach hundreds of officials, so even if Zhang Yushi's official position is lower than He Sizheng, He Sizheng is not willing to slack off.

Zhang Yushi turned over and got on his horse and galloped all the way to Suzaku Street in the scorching sun.

At that time, Liu Qingsong opened the curtain and looked outward, and he felt that one person and one rode on the hot air seat, "Huh? Liu Qingsong leaned out of the small window and stared at the dust for a long time.

Ran Yan 'fiddled' the ice cubes in the copper bowl, looked up at Liu Qingsong's posture, and there was a rare undisguised surprise on his face. The window was so small that it couldn't even compare to the size of an ordinary basin, and he was able to get out and retract it easily.

"You, what kind of expression is this!" Liu Qingsong turned his head and was startled by her, and immediately shrank into the corner of the carriage, "I said Forensic Doctor Ran, I'm used to seeing you with facial paralysis, and occasionally my expression makes me a little cautious." ”

Ran Yan's face darkened, she always knew that Liu Qingsong was thin and could shake in the fourth-level wind, but she didn't expect it to be a bamboo pole, "I think this window is twice as big as it is opened, and Xiao Yuezhi may not be able to pass through easily." ”

Liu Qingsong glanced at her with hanging eyes, and did not continue the topic, "Let's not talk about this first, I finally remembered who that person was!" ”

"The one who rode by?" Ran Yan said.

Liu Qingsong nodded, "I saw him in the morgue just now, he was one of the two officials beside He Sizheng, I only thought he was familiar at the time, but I was much more familiar with the officials of the Manchu Dynasty, so I didn't care." I just saw him riding a horse, and I suddenly remembered that I had seen him before, and that person was not an official of Dali Temple, but a person from Yushitai. ”

"Goshidai?" Ran Yan frowned.

The duty of impeaching a hundred officials made the court officials and their families have no good impression of them. The imperial history of these three courts is an important official of the Qing Dynasty, although the rank is not high, but the authority is very heavy, so the officials hired must be honest and upright. But Ran Yan 'privately' thinks that under such a appearance, the most important thing as a royal historian is to have a moment of love for gossip.

"I'm afraid that my autopsy will be 'revealed'." Ran Yan lowered his eyes. This matter may affect Xiao Song, but it is not too serious, after all, she was passively involved in this matter and did some cover-up, just to clear her grievances.

The two were silent, the roof of the car sank slightly, and from the gap in the curtain that had just been rolled up by Liu Qingsong, a note folded into a goose shape was thrown in.

Liu Qingsong leaned out of the car again.

Ran Yan picked up the note, only to hear Liu Qingsong sigh, "Wow, hero, you are wearing such black and hot......

Then there was a "uh" and there was no follow-up.

"What's wrong?" Ran Yan's heart tightened slightly, thinking that Liu Qingsong had been slashed on the neck, so he hurriedly dragged him in.

Liu Qingsong 'rubbed' his brain 'door' in a daze, and after a while, a large bag was raised, and he could vaguely see that it was a long shape, similar to the hilt or scabbard of a sword.

"I think you and Sang Chen are really ......" Ran Yan couldn't think of any adjectives for a while. Listening to the meaning of Liu Qingsong's words, he may have seen the secret guard, since people are 'masked', they naturally don't want to 'reveal' their identity, Liu Qingsong actually shouted loudly on the street, no wonder he was knocked with a stick.

Ran Yan also ignored him anymore and opened the note in his hand.

Qingjun's fluttering handwriting came into view, and the more Ran Yan looked at it, the more his brows wrinkled tighter, and after reading it, he dipped the note in the bowl of ice, and the black 'colored' ink bloomed in the melting ice water.

"What was written?" Liu Qingsong hurriedly picked it up with his hand, and the handwriting on it was already blurred.

"Someone's going to do something to me." Ran Yan's voice was heavy, and he immediately raised his voice and said to the coachman, "Speed up and go home." ”

The coachman answered, and sped up a little.

"Li Tai?" Liu Qingsong asked with a lip shape.

Ran Yan's jaw head.

Liu Qingsong's expression also became serious, he had been chasing Su Fu with Xiao Song for more than half a year, so he was naturally very familiar with Su Fu's figure, and there was a chance that the person was him.

"You and Su 'Yao' Master really have a 'leg'?" Liu Qingsong whispered with a gossip on his face, "Otherwise, how could he betray the Lord and come to inform you of this in person." ”

Ran Yan stared at him expressionlessly, until Liu Qingsong was numb and shrunk his neck, "It's okay for me to have a 'leg' with him!" ”

"Yes." Ran Yan crushed the soaked paper with his fingers, then took out a handkerchief and calmly tried his hand, adding, "It is too embarrassing for Master Su to practice himself like this. ”

"I deeply feel that the Holy Lord is really wise, so he should send Jiulang out." Liu Qingsong said.

It's a joke, but Liu Qingsong is not at ease in his heart.

It wasn't until the carriage drove into the house that he breathed a sigh of relief.

After Ran Yan bathed, he cooled down in the 'medicine' room in the house. This is the room that Xiao Song specially prepared for Ran Yan, warm in winter and cool in summer, very comfortable, two ice basins are placed in the corner, the indoor temperature is cool and pleasant, and there is no feeling of heat in the summer.

"I don't know if Suzhou is hot." Ran Yan touched the medical book, but muttered in his mouth.

After sitting for a long time, Ran Yan got up and opened the window. The heat rushed in, and was 'forced' back a little by the coldness, and Ran Yan only felt warm.

Here you can overlook half of Chang'an, under the scorching white light, the houses seem to be steaming hot, there are very few pedestrians, it looks lonely.

In Yankang Fang, which is separated by a few streets and alleys, Li Tai's mansion is full of singing and dancing.

Li Tai spends more than the prince every month, and the house does not know the elegant charm, but it is worth a lot of money everywhere, and there are sixteen ice cages in the house, exuding a trace of coolness, and all the fruits on the table are placed on the crushed ice, which is refreshing.
