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

The truth came so suddenly and so violently that everyone was involuntarily put into Shen Yujing's cell by Li Xiangnan's words.

It seems that the people who fell down due to poisoning were themselves!

The dark, damp, and cramped cell, the feeling of losing freedom and the inability to relieve the melancholy in one's heart, seemed to envelope each of them, making them tremble and shudder with fear due to the pouring rain, the dark clouds, and the darkness of the cell.

Outside the window, as if it were an omen, thick dark clouds were blown from the mountainside to the sky above the prison by the strong wind, covering the entire space.

The dark, dull, serious and dignified atmosphere suddenly made it hard for everyone to breathe.

But if the truth is indeed as Li Xiangnan said, then it naturally brings about countless problems that need to be solved urgently!

"That's not right, Consultant Li!"

The first person to ask the question was Prison Warden He Yong.

His words were like thunder from the sky, bringing everyone back to their senses.

"What's wrong? He Jian!"

The person who asked him was Wang Hebing.

Li Xiangnan also recovered from his previous excitement and looked at him calmly. His cold eyes met his and he asked, "He Jian, what's wrong? What's wrong?"

"After hearing the loud noise coming from Shen Yujing's cell, our prison guards immediately went over to check. After discovering him collapsed, several guards quickly opened the door and rushed in to see what was going on..."

Li Xiangnan nodded and continued, "In other words, you went in to rescue them immediately?"

"That's right!" He Yong wiped the sweat off his face and said affirmatively: "When Shen Yujing got into trouble, the prison guards were more nervous than anyone else. They saved lives and reported to the leaders. We also entered Shen Yujing's cell as soon as possible!"

Li Xiangnan looked at Guo Qian.

"Superintendent He is right," Guo Qian nodded and reminded, "We asked several prison guards on duty yesterday, and they did enter the cell immediately after Shen Yujing got into trouble!"

"That's right!" Wang Hebing nodded in agreement. "After receiving the news, Supervisor He and Supervisor Wei rushed to the scene as soon as possible even before leaving the office!"

He Yong said excitedly: "So, Consultant Li, you just said that Shen Yujing's cell was full of poison gas, then we prison guards, even the three of us, should have been poisoned as well, why are we not hurt at all!"

Hearing this, everyone once again fixed their eyes on Li Xiangnan.

Obviously, there are loopholes in what Li Xiangnan said.

Yes, Shen Yujing was poisoned. After he fell to the ground, the prison guards went in, He Yongweiting and Wang Hebing also went in, and even the comrades on duty from the Discipline Inspection Commission and the Procuratorate went in to rescue him. Three prison doctors also rushed over at the first time. If the poisonous gas filled the entire room at that time, then everyone who went in should have been poisoned, not just Shen Yujing lying on the ground!

It should be a large area lying there, neatly arranged!

Everyone had the same doubts, and even their gazes were highly consistent at this moment. They looked at Li Xiangnan, expecting him to answer everyone's doubts.

"He Jian, you overlooked a detail I just mentioned!" Li Xiangnan looked at him with a smile.

"What details?" He Yong swallowed nervously.

"Didn't I mention that Shen Yujing's cell faced the mountains to the west? Under the strong atmospheric pressure, the rain and the mountains exerted pressure on the cell, and the air flow poured from the high-pressure area to the low-pressure area, pushing all the poison gas into the cell through the exhaust window! And when Shen Yujing was poisoned, the heavy rain outside had not stopped yet!"

"Yes, yes, you did say that!" He Yong nodded in admission.

"But after Shen Yujing fell to the ground, did you open the door?"

"Of course, how can we get in if we don't open the door..." He Yong subconsciously retorted, then stopped talking mid-sentence. He also realized the point Li Xiangnan wanted to make and said in surprise, "Are you saying that after we opened the door, the poison gas escaped?"

"what?"

"If he lets him go, won't the entire corridor be filled with poisonous gas?"

"But why didn't anyone in the other cells get poisoned?"

A series of exclamations suddenly rang out at the scene.

Li Xiangnan wasn't surprised by the discussions. He looked at the stunned crowd and said calmly, "After the cell door was opened, the low-pressure area was connected to the corridor outside. The strong mountain wind pushed the poison through the air vent into the cell. When the door was opened, the airflow was pushed into the corridor. However, the corridor was not airtight, so the airflow had formed a loop and was dissipating in all directions. The concentration of the poison gas was no longer enough to poison people!"

Everyone's eyes widened, and they realized the change in the environment after the door was opened. It was precisely because of this reason that the poison gas was not so strong.

Many people looked at Li Xiangnan with a changed look in their eyes. At this moment, they really felt that this guy was omnipotent and had even thought of this so thoughtfully.

"And I just mentioned a piece of information, please pay attention!"

Wang Hebing said urgently, "Advisor Li, please speak!"

His tone was full of admiration and a greater desire for the truth.

"I told you, phosphine gas is heavier than air. After it's produced, it will keep moving downwards. When the entire room is filled, up to the height of the air vent, it will then escape out of the air vent! Have you noticed the height of the air vent? It's two and a half meters above the ground. Before the door is opened, it will envelop Shen Yujing, but once the door is opened..."

"Once the door is opened!"

At this time, Li Xiangnan's brilliant reasoning and analysis made Guo Qian, who had been investigating the case for twenty years, feel like he had found a confidant. He couldn't help but take over the conversation and said excitedly:

"When Shen Yujing first entered the room, the poison gas dropped a little, but the amount was small. It still enveloped him, causing him to continue inhaling the poison until the poison took effect! When the door opened, the air began to dissipate toward the corridor, and the poison gas's level also dropped rapidly. This level passed through everyone's mouths and noses, so when I asked the prison guards and the comrades from the Discipline Inspection Commission yesterday, they did smell a certain garlic smell, mistakenly thinking it was the smell of today's food. Then, with the door open, the poison gas quickly dissipated outside. The content and volume of the poison gas in the cell quickly decreased, below the breathing height of the mouth and nose. Even though everyone squatted on the ground to rescue him, the escaping poison gas was also rapidly decreasing. The concentration of the poison gas at that height was no longer enough to poison people - so no one was poisoned except Shen Yujing!"

"Ouch!"

When Guo Qian revealed everything that Li Xiangnan had not yet said, everyone exclaimed in surprise and suddenly realized what was going on.

"So that's it!" Wang Hebing's eyes flickered in disbelief.

Li Xiangnan smiled and nodded. "Yes, Captain Guo's reasoning is perfect! This is the risk-avoidance benefit of human height. Because poison gas is heavier than air, once the environment begins to change and the altitude continues to decrease, people can no longer smell the poison gas! And they won't be poisoned!"

"Brilliant! Absolutely brilliant! Xiao Li, your reasoning logic is truly flawless. I'm in awe! I've never participated in a case investigation before, but today I had the honor of participating. To be honest, I never expected it to be so satisfying!"

Even Mr. Wang Dong couldn't help but applaud.

The applause suddenly became intense.

As the applause gradually died down, Wang Hebing, He Yongweiting and others couldn't help but feel a sense of fear.

Li Xiangnan naturally knew what the relief on their faces meant.

When the room began to quiet down, he knew that everyone's last doubt began to take hold in their minds one by one.

Wen Xianping was the calmest person at the scene.

He squatted on the ground for a while, observing the phosphine gas completely dissipating into nothingness. Then he turned and asked, "Advisor Li, this reasoning is perfect, but what I want to ask is, who is the murderer?"

"Wow!"

As soon as this question came out, the scene immediately fell silent, even the sound of breathing could not be heard, and everyone looked at Li Xiangnan with bated breath.

Li Xiangnan smiled slightly and pointed to the blackboard.

"Weren't you all wondering just now why only Shen Yujing was poisoned while everyone else was fine?"

"If I told you that this murderer was not only familiar with all aspects of our prison and the structure of the cells, but was also proficient in subjects like physics and chemistry, had a sufficient understanding of meteorology and astronomy, and possessed extremely strong logic and a superb IQ, what would you think?"

"Because of him, even killing Shen Yujing alone was perfectly accomplished! The cell door opened, the poison gas descended, dissipated, and poured in. He even anticipated and planned it!"

"Then please tell me, Warden He, who is this murderer in prison?"

As soon as these words came out, the whole place was silent.

Everyone's hearts skipped a beat in shock, and they subconsciously covered their mouths, because if they didn't hold their hearts in, they would jump out of their throats...
