Rebirth 78, the beginning of the marriage was broken off by the female educated youth

At this moment, Li Xiangnan's heart was slightly shaken.

Shen Yujing was rescued, but in his heart, he always suspected that there was something wrong with the dose of poison!

The content of zinc phosphide powder in the food residue from his gastric lavage was extremely low, and it was almost impossible for it to reach the level that caused Shen Yujing to be severely poisoned.

Therefore, Li Xiangnan had doubts about how Shen Yujing was poisoned.

Although based on reasoning, it was initially inclined to believe that Shen Yujing was suffering from food poisoning.

But now it seems that this is not the case at all!

Shen Yujing was most likely poisoned by inhaling gases containing zinc phosphide!

As for the fact that the inhaled ingredients are not in the lungs but in the stomach, Li Xiangnan has not figured it out yet!

But now that we have a direction, it's a major breakthrough.

Without saying a word, Li Xiangnan returned from the door to the bottom of the air vent and looked up.

This is an air vent only the size of an A4 paper. It is completely blocked by iron bars as thick as a thumb. There is no glass. It is about meters from the ground and is located in the upper area of the entire prison. It is about half a meter away from the top.

Shen Yujing's bed is right under this air vent.

Li Xiangnan lifted the quilt and jumped onto the bed. His height was just enough to see outside through the air vent.

But at the moment he was not in the mood to appreciate the scenery outside, because he immediately realized that something was wrong.

One could actually smell a faint, familiar "garlic smell" here, which was more obvious than in other places in the cell.

The smell was masked by the musty smell and disinfectant smell of the cell itself, and it was difficult to detect unless you smelled it specifically.

There is a way!

Li Xiangnan's eyes lit up and he sniffed hard again.

Besides a hint of garlic, he also smelled a hint of dampness.

Moisture?

what happened?

He frowned and thought for a moment, then looked outside. Even with the flashlight, it was still pitch black and he couldn't see clearly. He couldn't figure out where he was outside.

However, the more confused he was, the more motivated he became.

Without saying a word, he took out a glove from his pocket and put it on his right hand, and with his left hand, he shone the flashlight around the thick iron fence to observe.

Li Xiangnan stood on tiptoe and used the flashlight to carefully illuminate the iron railings and the edge of the cement window sill on the inside of the window sill.

He searched the area almost inch by inch, and soon his eyes lit up. Sure enough, at the base of several iron railings and in the cracks of the rough cement window sills, he found a very small amount of almost unrecognizable gray-black powdery substance!

“So it’s really here!”

Li Xiangnan lifted up his shirt, shook out the bag of gold needles, took out a gold needle from the bag, and took out a tiny bit of the powdery substance to look at it carefully.

Under the light of the flashlight, it was discovered that the powder was almost identical to the contents of Shen Yujing's stomach in color, properties, gloss, and hardness.

He jumped out of bed, took the toilet paper and climbed back up, carefully using a gold needle and paper to collect all the suspicious things near the iron railings of the windowsill.

After he finished his work, he lit a cigarette in the cell, took a puff while standing under the air vent, and slowly exhaled toward the air vent.

Soon, the smoke that came out of his mouth was blown away by the fresh cool wind coming in from outside in front of the air vent, and it immediately dissipated and escaped forward.

Li Xiangnan frowned and looked in the direction where the smoke was blowing away, then his whole body suddenly trembled.

The direction in which the smoke dissipated was where Shen Yujing's plate was overturned.

Soon, a hypothesis appeared in Li Xiangnan's mind.

"Is it possible that the zinc phosphide gas was blown in through the air vent and then spread into the cell, directly enveloping Shen Yujing as he sat there eating? Because the gas was so strong and toxic, he didn't even have time to eat before he fell to the ground, went into shock from the poison, and knocked over his plate..."

As soon as this idea came up, Li Xiangnan himself was amazed at his own imagination.

Moreover, this seems to be the entire process of poisoning Shen Yujing!

Finally figured out how Shen Yujing was poisoned!

This made Li Xiangnan instantly excited.

But I immediately broke out in a cold sweat.

You should know that zinc phosphide is a highly toxic substance. The most common items it appears in are rat poison and certain pesticides.

Its common form is a gray-black powdery solid!

But it was obvious that what poisoned Shen Yujing this time was the gas it produced!

The person who poisoned Shen Yujing not only knew how to circumvent regulatory review and avoid surveillance by the Discipline Inspection Commission, the Procuratorate and the prison, and was so familiar with the prison situation, but he was also so familiar with chemistry that he understood the physical and chemical forms and properties of poisons. He almost killed Shen Yujing invisibly and arranged a closed-room murder case that was almost impossible to detect.

Even Li Xiangnan was confused and mistakenly thought it was food poisoning, which led the investigation astray.

This meticulously planned poisoning case was flawless and comparable to a work of art. It was definitely not something a simple prison guard or a cook could do!

The other party must be a person with high IQ, meticulous logical thinking, and even amazing courage and boldness!

Could such a person be a prison inmate?

But if it wasn't someone from the prison, who could it be?

Li Xiangnan finished smoking a cigarette, stomped it out with his foot, and instead of throwing it into the squat toilet, he stood up again and reached out to put the cigarette butt outside the iron fence of the air vent.

A strong incandescent light swept across the iron fence, exposing the entire cigarette butt in front of the air vent, and then the surroundings fell into complete darkness.

In addition, Li Xiangnan saw grass growing outside and water droplets hanging on the grass branches!

Is there a river or a ditch outside?

No wonder this cell is so humid!

But thinking back, Li Xiangnan was not so sure.

He still knew the approximate location of Qincheng Prison. The nearby river was some distance away from here!

Could it be that some ditch was built here?

No matter what, we must check the environment outside the air vent tomorrow morning!

Because this may directly point to the culprit of the poisoning.

He turned back and sat down beside the iron gate, leaning against the large iron gate covered with soft leather, looking at the air vent that flickered, and fell into a deep sleep.

He didn't know when, but in a daze he suddenly saw a face appear in front of the air vent, leaning over and smiling sinisterly at him.

The face was vicious, cold, cunning, and cruel. Streams of ink-like black air spurted out of his mouth, and his laughter was loud and cold.

In the end, the face was bleeding from all seven orifices, and suddenly it turned into Shen Yujing's face!

"Shen Yujing!"

Li Xiangnan roared and suddenly sat up. Only then did he realize that it was bright outside and everything that had just happened was a dream.

He turned his head to look at the air vent, and as if possessed, he ran over and jumped onto the bed. The cigarette butt he had placed there last night was gone!

"Advisor Li!"

Someone suddenly opened the iron gate and asked with concern, "Are you okay?"

Li Xiangnan turned around and saw the person coming. He jumped off the bed calmly and shook his head, "I'm fine, Dean Fei!"

He subconsciously raised his wrist. It was just past six o'clock. When he walked out the door, everyone in the corridor looked at him in horror.

Guo Qian and Rudenko were probably on duty all night and were sleeping soundly.

The director of the procuratorate, Fei Yiqing, seemed to be hesitant to speak, and several times he cut himself off from the words that were on the tip of his tongue, his mouth corners constantly controlling the trembling muscles.

Last night, Wei Ting, He Yong and Wen Xianping came one after another with different purposes, but only Fei Yiqing from the Municipal Procuratorate did not show up. He is really patient.

Li Xiangnan knew he had something to say to him, so he smiled and said, "Dean Fei, are you familiar with the area behind Shen Yujing's cell? Could you take me there?"

"Behind the cell?" Fei Yiqing was stunned, then his face lit up with joy. "I'll take you there, Consultant Li!"

Li Xiangnan nodded, then followed him step by step out of the prison area. When they passed through one iron gate after another and finally saw the rising sunlight outside, he asked, "Dean Fei, why do you think Shen Yujing was poisoned?"

Li Xiangnan stood inside the door and looked outside.

What I saw was a bright sunshine.

Fei Yiqing stood in the sun and looked inside the door.

All I saw was chaos and darkness.

Light and shadow change at this moment, and consciousness is intertwined at this moment.

Fei Yiqing said calmly but meaningfully, "I think Shen Yujing committed suicide."

He Yong believed that Shen Yujing died due to torture by the Discipline Inspection Commission and the Procuratorate.

Wen Xianping believes that Shen Yujing was killed to silence her by the prison or some other force.

However, Fei Yiqing, the president of the procuratorate, believed that Shen Yujing committed suicide.

interesting!

Li Xiangnan took out a cigarette, handed it over, and asked, "President Fei, why do you make such a judgment?"
