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

“It’s just as I expected!”

Hearing this, Li Xiangnan raised his head from the mass spectrometer. The instrument in front of him was still working, making a slight roar. The mass spectrum was pulling a long line outward, and the two-dimensional chart on it was slowly becoming clearer and more specific.

Qin Ruobai and Xu Qiluo looked at each other, their faces showing curiosity and a strong desire for the truth.

"Xiangnan, what did you find?"

Li Xiangnan did not answer her first, but smiled at Ye Buping who was standing by the door and said, "Director Ye, please close the door, thank you!"

Ye Buping closed the door and walked over quickly. He was also very curious about what valuable information Li Xiangnan could find from a mass spectrometer.

However, he was still somewhat in awe of the police handling the case, and asked cautiously: "Two police comrades, can I...can I listen? Otherwise, I'll go out for a while?"

Qin Ruobai shook his head. "Just follow the rules and keep it confidential! Don't leak the contents of this laboratory!"

"That won't happen, absolutely not!" Ye Buping quickly promised.

After nodding, Qin Ruobai turned his gaze to Li Xiangnan.

"Pen'er, Xiao Xu!" Li Xiangnan waved to Xu Qiluo on the side.

"Okay!" Xu Qiluo was very attentive. At this time, he had a great understanding of Li Xiangnan's abilities.

He found a small knife nearby and gently scraped the substance on the side of the enamel basin. Li Xiangnan held up the tip of the knife and explained:

"This is a substance produced by industrial liquor and the rust on the bottom of the basin. When the basin fell to the ground, a chemical substance was produced during the agitation process. It is a chemical of methanol and iron!"

"This proves that one of the substances in this basin is indeed methanol!"

Qin Ruobai nodded slightly, "You mentioned earlier that there are also acidic and alkaline solutions?"

"That's right!" Li Xiangnan scraped the middle of the basin again, held it a little further away, and explained: "This is the methyl ether formed by the combination of light sulfuric acid and methanol and the moisture from tears!"

Both police officers were a little confused and didn't understand the meaning of this term.

Seeing that neither of them understood, Li Xiangnan paused and said, "You don't need to understand what these are. Just know that they have a corrosive effect on human eyeballs!"

At this time, he got the mass spectrum, pointed at the molecular analysis chart on it, looked at it carefully, and suddenly realized it. He said solemnly: "In fact, in addition to these two substances, there is another thing that I overlooked before!"

"What is it?" Xu Qiluo blurted out this time. He was obviously shocked by Li Xiangnan's profound knowledge and couldn't wait to know the truth.

"White oil!" Li Xiangnan said without thinking.

"What is that?" Ye Buping on the side was also very curious.

"A highly refined product, colorless, odorless, non-toxic industrial white oil! Mainly used for chemical fiber products and their injection molding packaging!" Li Xiangnan told everyone using future experience.

Qin Ruobai was even more puzzled, "Xiangnan, what is the purpose of this thing appearing in the washbasin?"

"I ignored the smell of mild sulfuric acid and industrial liquor before. If these two things were put together, any normal person would know that there was something wrong with the water in the basin from a few meters away! But Senior Brother Zhang washed his face without thinking. He is not a fool. Why would he do this?"

Qin Ruobai and Xu Qiluo looked at each other, exclaimed, and both felt like they realized something too late.

"So, the person who wanted to harm Senior Brother Jingyang and Zhisheng put this white oil in this basin. The density of white oil is lighter than liquor and sulfuric acid, so it will float on these two substances. Because of its colorless and odorless properties, it covers up the smell of liquor and sulfuric acid! Senior Brother Zhisheng mistook it for water. He was in such a hurry to attend the art exhibition that day that he wanted to take care of himself and rush to the Imperial College! That's why this happened!"

"Hiss!" Qin Ruobai suddenly realized and couldn't help but admire Li Xiangnan. "Xiangnan, what you said is just like recreating the crime scene at that time!"

"Yes, Dr. Li, what you said makes a lot of sense. It feels like you are there!" Xu Qiluo was full of admiration.

But after listening to Li Xiangnan's words, Qin Ruobai still had some thoughts of his own.

"So this person is very familiar with Zhang Zhisheng and Zhang Jingyang's whereabouts. He is probably someone very close to them! He even knew that they were in a hurry to go to the exhibition, so he took advantage of the opportunity!"

"That's right!" Li Xiangnan also narrowed his eyes and asserted, "So, the direction of your investigation is now more precise. First, this person is very close to the Zhang family. Second, this person is very familiar with chemical products! It is very likely that he is someone who can come into contact with white oil and can set up such a sophisticated trap to harm Senior Brother Zhang, or he is a worker in the chemical plant!"

"Hiss! Master, let's go catch the bad guys! Oh my god, Doctor Li is so awesome, he's simply a master at investigating cases!" Xu Qiluo immediately became excited, his face full of the urge to try.

"Xiangnan!" Qin Ruobai's eyes lit up when he finally got a clue. He looked up at Li Xiangnan with eyes full of gratitude, "I... I don't know how to thank you!"

"When you solve the case, treat me to a meal!" Li Xiangnan also realized another career path from this incident, "I will show you a way to help the police solve the case!"

After hearing what he said, Qin Ruobai's eyes were as bright as the stars, and she immediately became happy and couldn't wait. She even wanted to pull Li Xiangnan's hand, but because there were several people here, she had to hide the excitement in her heart, "You... just tell me a little bit, okay?"

Li Xiangnan smiled slightly and said, "Forensic Identification Department!"

"Hiss!" Qin Ruobai's hair stood up when he heard this. After experiencing what happened today, the role of this specialized department in criminal investigation is self-evident.

"Don't worry, I'll help you later! Go to the bureau and report back!" Li Xiangnan cut out the data from the mass spectrometer and handed it to her, emphasizing, "Industrial white oil is still in short supply. The chance of it appearing is not high, and the range is easy to locate! I'll wait for your good news, go and catch the guy!"

"Yeah!" Qin Ruobai nodded. The gratitude and admiration in his heart were overflowing. He really wanted to chat with Li Xiangnan here more, but he couldn't relax on his work tasks. He could only smile knowingly at him and hurried away with Xu Qiluo.

"Wow, Xiao Li! You're really something! You even know how to use a mass spectrometer!" Ye Buping had been watching from the side for a long time, and the more he watched, the more amazed he became.

"Besides, your knowledge of biology and chemistry far exceeds mine. Are you a freshman?"

Seeing Ye Buping's surprised and shocked expression, Li Xiangnan smiled slightly, hiding his achievements and fame, "Old Ye, I'm just lucky. I know a little bit, and it just happens to be what those two friends need!"

"Just talk to me! I finally understand why President Yan spent so much effort to recruit you into Yan University. You are a real talent!" Ye Buping suddenly figured it out.

It would have been fine if he didn't mention Yan Song. As soon as he mentioned this, Li Xiangnan smiled and said, "Old Ye, the work here is done. Come with me to find Old Yan!"

"I do need to visit Principal Yan, but...what do you want?" Ye Buping asked puzzledly.

"You went to hand in your work-study report, right? I heard from Lu Chen that you talked to him and the department stamped your report, right?"

Ye Buping grinned and said, "I can't hide anything from you, kid!"

Li Xiangnan smiled when he heard this, "After all, I am also a participant in the work-study program! I really need to talk to him about this matter! There is one more thing, which is more important!"

"What's the matter? Do you need my help?"

"CT Scanner!"

"What chicken?"
