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

Qincheng Prison, next to the infirmary.

Everyone involved in the poisoning case rushed here upon hearing the news.

The prison warden He Yong, deputy warden Wei Ting, political commissar Wang Hebing, chief of the inspection section of the Discipline Inspection Commission Wen Xianping, president of the procuratorate Fei Yiqing, captain of the criminal investigation brigade of the municipal bureau Guo Qian, as well as the three doctors Lu Dingkun, Wang Dong and Liu Yishou who stayed here, Wang Defa, vice president of Nianwei Hospital, and relevant case handlers from several units.

Everyone gathered together. Although they were required to wear thick masks, one could still see the nervousness and anxiety on their faces, and their eyes were all focused on one place - looking at Li Xiangnan, who was in the eye of the storm.

Li Xiangnan, who was being stared at by countless pairs of eyes, was now standing among a pile of prepared glassware.

"This is normal dust powder on the prison windowsill!"

Li Xiangnan held up a piece of glass with a handful of dust on it. After he lowered it, he walked in front of everyone so that everyone could see clearly the experiment he was going to prepare.

But just as he was about to pour in the acid solution, he suddenly lifted the glass upright, and the whole pile of dust fell into the trash can.

"Hey?"

Some public security comrades who were confused stood up and expressed their confusion about his behavior.

"The sample I collected is not common enough!" Li Xiangnan shook his head, smiled at the person who asked the question, and then walked to the window, scraped the powder on the windowsill with moist filter paper, and put it into a small glass bottle.

"The environment of the entire prison is the same, so the dust marks on this windowsill are no different from those inside and outside Shen Yujing's cell!"

After he said this, many people who had just left their benches sat back down.

"Everyone, please look!"

As Li Xiangnan spoke, he used a dropper to take out a dilute hydrochloric acid solution from a bottle beside him.

"This is dilute hydrochloric acid!"

He dropped the dropper into the glass bottle until the entire test tube was empty, but there was no chemical reaction in the bottle.

He handed the glass bottle to Wang Defa, "Defa, let everyone see the situation!"

"Yes!" Wang Defa held the glass bottle curiously and looked at it for a long time. He passed it around to the people around him and confirmed, "Your experiment was in vain!"

Li Xiangnan smiled and said, "It was just for reference!"

"Oh?" Hearing this, Wang Defa suddenly realized.

Then, Li Xiangnan did the same thing, scraping the gray-black powder he had collected into another glass bottle and signaled, "Everyone, put on your masks!"

His reminder drew all eyes over again.

While staring, Li Xiangnan took a dropper of acidic solution and dripped it into the glass bottle.

Chi!

Just one drop, and the glass bottle clamped on the iron rack immediately made a sound, and a violent chemical change occurred inside.

Chi!

Chi Chi!

"what?"

Accompanied by screams, the test paper covered with powder in the entire glass bottle turned black in an instant, and then a thick gray mist rose up and lingered in the bottle for a long time.

Everyone stood up.

Li Xiangnan stood three steps away, frowning as he looked at his experimental results, with the corners of his mouth slightly raised.

It’s just as I expected!

This thing undergoes a chemical change when it comes into contact with acid!

"Advisor Li, are those the toxic gases you mentioned?"

"Could this be the culprit that caused Shen Yujing to suffer from the poison?"

"The black powder is gone, it's gone!"

There were exclamations one after another in the room, and many people stood up with excited expressions.

"Don't worry, everyone!"

The experiment was not yet complete, so Li Xiangnan reached out and pressed down. His eyes were not on his own experimental equipment, but on the people around him.

"Everyone sit down!" Guo Qian shouted to everyone around.

Among the people present, only Wen Xianping and Fei Yiqing remained seated without moving.

The most excited people were the two prison wardens, He Yong and Wei Ting.

On the other hand, Wang Hebing's expression contained a complicated sense of relief, as if he was relieved that Li Xiangnan had found the truth?

After taking in the reactions of everyone present, Li Xiangnan withdrew his gaze.

Then, he put down the glass bottle of dilute hydrochloric acid, took a glass of water from the side, and said, "Everyone should be familiar with this, right? This is water, drinking water!"

"Eh? Don't..."

As soon as Wang Hebing shouted this, Li Xiangnan pursed his lips and took a sip.

He then handed out the enamel pot and showed it to everyone.

Amidst the exclamations, everyone once again fixed their eyes on Li Xiangnan.

"This is just ordinary water! It can be well water, river water, or even rainwater!"

Li Xiangnan said these words softly, his words full of hints.

But everyone just listened and did not have any unnecessary associations at this time.

Then, he moved the entire glass of water to another glass bottle, which still contained a lot of gray-black powder he had collected.

He raised his hand and saw that everyone had slightly moved their buttocks away from the bench. He smiled slightly and poured some clean water into the bottle.

"Hey!"

The chemical reaction was even more intense than before. A thick smoke suddenly escaped from the small glass bottle and flowed under the table like water.

This amazing scene left everyone who saw it speechless, with their mouths wide open in amazement.

Amidst everyone's shocked gazes, Li Xiangnan picked up the glass bottle with tweezers and turned it upside down on the table.

All the gray fog poured over the table like a stream of water, and then flowed towards the low ground.

Everyone subconsciously took a step back.

"Advisor Li, please be careful!" Guo Qian reminded him with concern.

"Don't worry!" Li Xiangnan waved his hand and reminded him: "Captain Guo, step back!"

"Give it to me!" Wang Defa on the side took the enamel pot from his hand.

"You step back too!" Li Xiangnan knew that he was also worried about being poisoned.

Wang Defa nodded and did as he was told, but he only stepped back slightly and did not walk far.

Da da da!

Then, there was the sound of a glass bottle hitting the table, which instantly shifted everyone's attention from the ground to the surface.

Soon, some thin, white scale came out of the bottle, standing out on the maroon table.

"This is the crystal formed after zinc phosphide reacts with water!"

Li Xiangnan pointed at the table and reminded everyone. After everyone looked over, he picked up the collection on the side and reminded them, "Are you familiar with this? The product of this experiment is consistent with what I looted outside Shen Yujing's window!"

Everyone looked at it intently, their eyes widened for a moment, and soon many people began to nod.

Guo Qian, the most investigative person, was more concerned about the logic behind this. He stepped forward, took a closer look, and asked with a puzzled look, "Advisor Li, are you saying that someone is conducting experiments outside Shen Yujing's ventilation window?"

"what?"

There was a cry of surprise in the house.

He Yong, who was sitting in the middle, suddenly had a pale expression. He slapped his thigh and yelled, "You're so familiar with the experimental procedures... I think... Prison guards, arrest Dr. Hao and the other two doctors! They're serious suspects!"

"???"

The three doctors standing outside the window watching the "performance" looked at each other in bewilderment.

Hurala!

Almost in an instant, the three were surrounded.

"He Jian, this is unfair! How could we poison you?!"

"He Jian, we are good people. This is none of our business. We don't know what's going on!"

"Superintendent He, Supervisor He, we've made a mistake... Advisor Li, we're innocent, we're not murderers!"

Li Xiangnan, who was about to explain, now looked at Warden He speechlessly and shouted, "Warden He, I haven't finished speaking yet. If you want to arrest someone, don't be so anxious!"

He Yong's face was covered in sweat. He swallowed several times before asking, "Advisor Li, are you saying the murderer is someone else?"

Wang Hebing, however, was more concerned with the truth of the matter. He frowned and asked, "Advisor Li, what exactly are you trying to tell us by doing this? How did all this happen?"
