The results were only one page, and they simply stated the names of the chemicals in the powders and liquids in the bottles. Pen "Fun" Pavilion www.biquge.info

Full name of chemical: N-dimethylnitrosamine.

"Coated paper is a high-grade paper. This kind of paper can only be used by residents of cities with high inhabitant ranks. ”

"I think the criminal put two forms of chemicals in Yin Yingnan's bedroom, and he wants you to guess how Yin Yingnan was poisoned. ”

Di Qi's tone was low, and the result seemed even heavier.

Jiang Mumu has traveled through these modern urban planes, and has also learned some about the hierarchy of residents in this world.

The inhabitants of this world are hierarchically linked to all aspects. For example, everyday items.

There are a lot of things that can only be used by high-ranking residents.

For example, for example, the coated paper found by Jiang Mumu.

Coated paper only exists in cities above the marginal area, and cities below the marginal area will not sell this paper.

For example, obsolete miniature devices. This kind of stuff will only be dumped in the slums of city level 0.

And this kind of high-grade electronic products that have not been eliminated only exist in the Tang Kingdom - Park District City City of City Level 7.

It can only be used by residents who have Resident Level 7+.

Residents of Resident Level 7- can only use ordinary electronic products.

"Do you think the mastermind is a resident of a city in the marginal zone?"

Xiang Junqing suddenly inserted himself into the conversation between Jiang Mumu and the two.

"Hmm. ”

Di Qi replied lightly. The three suddenly fell silent.

Residents of cities in marginal areas have the right to administer only government agencies of the same or higher city level, and government agencies below the city level in marginal areas have no authority to administer arrests.

"So, from the very beginning, the mastermind targeted the residents of the low-level cities, just because they could escape the legal punishment of the low-level cities?!"

Xiang Junqing asked in surprise. At the moment he looked a little resentful.

He looked at Di Qi's gaze a little strangely, and there was a certain unwillingness in his eyes.

Di Qi glanced at Junqing.

"Did you find anything on the barrel that the appraisal team took last time?"

Di Qi asked Xiang Junqing. The three of them walked and left the identification team.

The three of them entered Xiang Junqing's office and discussed Yin Yingnan's case.

"The cylinder's report hasn't come out yet. ”

Xiang Junqing replied. Jiang Mumu suddenly recalled and said.

On the day of Yin Yingnan's death, Ben Baobao asked a classmate in his dormitory. ”

Yin Yingnan's classmate said that when the baby made a sharp scream, Yin Yingnan did not wake up. And his sleeping position did not change from the time he fell asleep to less than two hours. ”

"There is also a particularly strange place, that is, Yin Yingnan fell asleep as soon as he lay down, and immediately there was an even snoring sound. ”

"On that day, the baby woke up screaming because of a nightmare. This voice alarmed many people and attracted many insults. However, the five people in this baby's bedroom, like Yin Yingnan, did not wake up. ”

"In a half-dream, the baby vaguely saw the fluorescent lamp in the room. This makes this baby feel strange. The school's rule is to turn off the lights at 10 o'clock at night, and it is impossible to turn on fluorescent lights indoors. But Ben Baby was sure he was not mistaken. ”

Jiang Mumu stopped as she spoke, she didn't continue to tell Xiang Junqing about the shadow she saw last night.

Yin Yingnan's classmates once said that he had changed his dormitory five or six times. Every time I change bedrooms, the reason is because it is too noisy and leaky. I can understand that this is too noisy, after all, it is a dormitory where many people live, and it will definitely not be very quiet. But the water leaks, which I don't understand. ”
