As soon as the words fell, the landline on Jiang Yuanhao's desk rang, and he immediately picked it up. "Hey, little junior sister~ Yes, Team Tang, they are all here with me, you say ......"

Tang Yunzhen also hung up the phone first, and looked at Jiang Yuanhao with Da Wei, but saw that his brows were getting tighter and tighter.

"Okay, I see, I'll pass it on. Jiang Yuanhao put down the phone and took a deep breath before speaking again. "The poison test in Yi Xun has come out, it's Siren. ”

"His uncle's ......" Tang Yunzhen felt that his head hurt even more, he knew that Yi Xun was Siren's person, and he also knew that there were other conspiracies behind this, but he didn't expect that he wouldn't even leave anyone with time to catch his breath. "Is there any end to it?"

"Apparently it was Siren who came to kill the mouth, and took the body away and didn't want us to continue the investigation. Da Wei also felt that the water was getting deeper and deeper in this matter. "I searched my body yesterday, and Yi Xun really didn't have anything on him, where did he come from, Siren! How did they find the opportunity to poison him?"

"It wasn't necessarily Siren's poison, it could have been eaten by Yi Xun himself. After Jiang Yuanhao's brainless words came out, Tang Yunzhen and Da Wei both looked at him in surprise.

"Regardless of Siren's origin, why did Yi Xun take the poison himself? His ghostly virtue didn't look like he would commit suicide in fear of sin. Da Wei was confused. "And yesterday, Sister Feifei said that if Siren is taken orally, the effect will be greatly reduced. Should...... Poison doesn't kill people?"

"Siren is different from the poison in the traditional cognition, in the cases we have come into contact with before, such as Zhang Meina and Ouyang Chen, they all have Siren residues in their bodies, but they are not dead from Siren's toxic reactions, so it can't actually be regarded as a poison, it can be classified as a hallucinogen, or a xingxing. Personally, I think it's more like a credit card, use it in small amounts and pay it back in time, there will be no problems, but if you use it in large quantities, overdraft, overdraft, and can't afford it, it will be life-threatening. Jiang Yuanhao said in popular science. "Fei Fei said yesterday is not wrong, if you take it orally, it will go through the digestive system, and the effect of Siren will be very weak, and what I said about 'eating it' is indeed putting the medicine in the mouth, but it is not taken orally, but under the tongue. ”

When Tang Yunzhen heard this, he probably understood. "Like taking a quick-acting heart-saving pill?"

"Yes, the oral mucosa absorbs the drug faster, and the drug absorption speed of the sublingual drug is second only to the aerosol, faster than the intramuscular or subcutaneous injection, and the drug is directly absorbed through the sublingual capillaries, without the gastric acid, which will greatly retain the efficacy. Although Jiang Yuanhao was very happy to see that Yi Xun could not die well, he felt that he would go so suddenly, and he would die too easily and too cheaply. "Siren is probably hiding in one of Yi Xun's teeth, or he may have a 'trap' in his mouth, as long as he bites into the corresponding place, the potion will pierce the gums and directly enter the blood circulation. I was careless, I should have pulled out every one of his teeth yesterday and had it checked. ”

"All pull...... Pull it out?" "Da Wei Tian is not afraid of the ground, but he is afraid of going to the dentist, some time ago he just extracted a wisdom tooth, he doesn't care if he gets bloody, how can the front-line criminal police be afraid of blood? A series of tools such as the bone hammer were inevitably beating and beating in front of his eyes, making it like construction on the construction site, and the feeling of being able to hear the echo of the skull every time he moved was really terrible, so as soon as he heard Jiang Yuanhao say that he wanted to extract his teeth, although he was not pulling him, Da Wei still subconsciously raised his hand to support his cheeks. "But Director Jiang, even if it's really like what you said, Siren's source can be explained, but it can't be regarded as poison, then Yi Xun will definitely not commit suicide in fear of guilt, so what does he want to do?"

"In fact, the purpose of Siren's original development was to strengthen the killer's combat effectiveness, but there was a little problem with the formula, so it was used as a poison by mistake, and it also needs a large dose to be fatal as a poison. Jiang Yuanhao is very disgusted with Siren, but he is also very curious. "In Siren's initial training, there were still people who not only resisted its toxicity after taking a large dose, but also used the stimulation it brought to the body, pushing the physical performance beyond the limit and completing the impossible task. If this Yi Xun is one of Siren's professional killers, maybe he has this special physique. ”

"Director Jiang, how do you know so much?" Da Wei looked at Jiang Yuanhao in surprise, his memory was not bad, he remembered very well the information about Siren as a potion in the Intelligence Department, only two short sentences, and there was no key information.

"What I just said is written in my master's notes, and I once dissected a corpse, which is similar to the situation you just described to Yi Xun, because he was poisoned by Siren and died, but I found that the temperature of his internal organs and the temperature of his outer skin cooled down at different rates, and there were signs of second-degree death, the first time it may be suspended animation. At that time, medical equipment could not detect too small signs of life on the surface of the body, so the doctor confirmed that he was dead and gave up treatment, but in fact, his internal organs were still fighting the toxins for the body, but unfortunately his own immune system could not save his life. Jiang Yuanhao shook his head regretfully. "There's only so much I can say, don't tell Yu Chu, I didn't allow her to read those notes, but I read them myself, and she knew that she was going to pester me again...... Well, and Feifei, the curiosity is too heavy, don't tell her, or ......"

"Otherwise, what?" Zhou Yanfei pushed open the door and walked in, she was still so vigorous and resolute, walking with the wind, but her posture was a little awkward, as if she had injured her leg, Yuan Xiangning followed behind and anxiously wanted to help her. "Senior brother, it seems that you still have some notes hidden?"

"Didn't you let you rest at home?" Jiang Yuanhao was arrested for 'doing bad things', a little embarrassed and embarrassed, he glanced at Yuan Xiangning next to him, and the other party looked innocent.

"Ah Hao, don't make your eyes look at you, it's useless. Yuan Xiangning said honestly. "We've been here for a long time, and Feifei heard what you just said...... The notes belong to the Master, and you brothers and sisters have the right to read them, so you shouldn't keep them private. ”

Jiang Yuanhao was almost helpless, he had less and less status at home, and now he didn't even have his daughter-in-law on his side.

Tang Yunzhen had already consciously walked to Zhou Yanfei's side, and naturally hugged her waist so that she could rely on him.

If it weren't for Zhou Yanfei's flat lower abdomen, the two of them would be in a position like a husband holding his pregnant wife at this time.

Tang Yunzhen behaved lightly on weekdays, and Zhou Yanfei seemed to be uncomfortable today, so he treated her so half-hugging and half-supporting, Jiang Yuanhao and Da Wei didn't think it was strange, but Yuan Xiangning didn't seem to be very happy, and glared at him viciously before giving up his position to Tang Yunzhen.

Yuan Xiangning used to be very polite to Tang Yunzhen, especially after Han Chuyan's accident, she even comforted him in different ways these days, cared for him when she saw him, and helped him cook, sent him fruits, and piled small snacks on his desk.

So she suddenly glared at her fiercely, although there was no lethality, but it still made Tang Yunzhen inexplicable for a while, I don't know where to offend her, and what reaction to make in response.

"Old Tang, if it is really said by my senior brother, then this Yi Xun is even more dangerous than before. Zhou Yanfei patted Tang Yunzhen's hand on her waist. "I have to inform my colleagues at the hospital so that they can be prepared. ”

"Yes. Tang Yunzhen hurriedly called Cheng Tingshen, who was still in the hospital. "Ting, Yi Xun may not be dead, let the brothers divide into groups of two to find it, don't be alone. If you find the target, follow it first, don't act rashly, and I'll bring reinforcements right away. ”

As soon as Da Wei heard Tang Yunzhen say this, he immediately ran out and went back to the task force to call someone.

"I'll go with you. After Zhou Yanfei finished speaking, seeing that although Tang Yunzhen hesitated, he still nodded, so he smiled, and then turned his head to look at Jiang Yuanhao and Yuan Xiangning. "Those notes from my brother's private collection, my sister-in-law will help me make a copy~"

"Okay! I'll copy it and send it to your office!" After Yuan Xiangning was called 'sister-in-law', she was a little embarrassed, and she felt beautiful, so she 'detained' Jiang Yuanhao to get the notes.

Tang Yunzhen and Zhou Yanfei didn't wait for the big Wei and the team they assembled, they went directly to the parking lot, and the two of them drove to the hospital first.

Although Tang Yunzhen believed in Jiang Yuanhao's professionalism and understood that what the other party said was a well-founded and reasonable inference, he always felt that this speculation was too mysterious, and the probability of encountering it in real life was too low.

He still felt that Yi Xun was dead, but the body was taken away by Siren's people, and they didn't pose much danger to Cheng Tingshen, who was still in the hospital, so he wasn't too anxious, and he didn't even have a police light on the road, so he honestly waited for the traffic light to change, and touched Zhou Yanfei's hand while he was in the middle of the day. "Where did I provoke Xiangning? Why did she keep glaring at me just now? Yesterday she was fine, and she stuffed two packets of spicy strips into my pocket. ”

"It's just staring at you, it's already the result of my persuasion, when she was at home just now, she wanted to cut you with a scalpel. Zhou Yanfei blushed a little and said slightly embarrassed. "I ...... I went home yesterday and took a pregnancy pill, and the rest was thrown on the table, she came to accompany me today, and when I saw it, I thought I was really Yi Xun yesterday. ”
