"More than 55% methamphetamine..."

"More than 77% of K fans..."

...

In the laboratory, when they touched it casually or smelled it through their noses, the three of them accurately explained the general purity of the drug.

Maslow inserted his hand into the heroin and gently rubbed it with his hands, "No. 3 heroin, purity of more than 55%..."

"No. 4 heroin, this one, 99.99% purity..."

No. 3 heroin is also known as "Hong Kong Stone", "brown sugar" and "white dragon ball". It is a granular drug, sometimes in powder form, with colors ranging from light gray to dark gray.

Pure or high-purity No. 4 heroin is a white, odorless, transparent powder that is so delicate that it will disappear when applied to the skin.

Qin Guanlan looked at the three young police officers with satisfaction, each of them made rapid progress. Maslow had already mastered the skill of inspecting goods. He rubbed it with his hands and could generally judge the purity of heroin based on his feel.

"Okay, now you don't need to hold the wall and put it in your mouth." Qin Guanlan smiled and looked at Jiang Xiaobai, and Jiang Xiaobai's face couldn't help but turn red.

Qin Guanlan ignored him, "Let's go, come with me."

Where to go?

Facing this crazy old man, this unconventional old man, this skilled old man, the three of them couldn't tell what they thought of him.

Police Superintendents? Academicians? It seems that in their twenty years of life, they have never imagined seeing such police supervisors and academicians.

The three of them followed Qin Guanlan downstairs and got into an ordinary car, but Qin Guanlan did not get into the car. The car slowly drove out of the courtyard. When he turned onto the overpass, Maslow looked at the street sign and knew that the car was driving towards the city center.

Jiang Xiaobai and Ju Hongfei also noticed the direction of the car. The three of them looked at each other, wondering what the old man was selling in the gourd.

Cars came and went in the city center, and soon the car pulled them to stop in front of an overpass.

"Down." Opposite is the famous commercial area, with people coming and going, bustling, and very prosperous.

Could it be that I brought us to shop?

But this thought just flashed by. People can never imagine the other person as being too kind at any time.

"At the overpass, everyone stared at the people below." The people who brought them looked serious, as if they were born to be unable to smile.

"Leader, what do we want to see?" There were people under the overpass. Ju Hongfei wondered, what were he looking at, was he staring at these people?

In the middle of winter, there are thick cotton coats wrapped around, what's the point? This is not summer, nor the famous art district!

"Look at these people and think about them."

The visitor said a word and left. In the cold wind, only three school police officers were left with big eyes and staring, scattered in the cold wind.

"This is also the content of the laboratory?" Jiang Xiaobai finally couldn't help it and took the lead in saying it.

This place is very familiar to him who has been in college here for four years. What are the good things about this place?

"Don't you understand? There are four more words to think about them." Ju Hongfei seemed to have reminisced about it, "Think about it, look, Maslow has been thinking about it."

Looking down from the high overpass, you will feel aloof. For some reason, Maslow suddenly remembered the first case he handled this summer, Li Yan'er, who was willing to stand on the top of the building and look down at the crowd!

Everyone lives wearing masks. Looking at the crowds of people who are in a hurry and the men and women with no joy, anger, sorrow and happiness on their faces, Maslow's eyes narrowed.

"Hey, Slow, what did you find?" Ju Hongfei came over.

"What did you find?" Maslow rubbed his eyes, "squinted."

cut!

However, just when he opened his eyes again, he found that everyone walked differently, some walked, some trotted, some raised their heads and chests, and some looked down at their phones...

Everyone’s clothes are different, including coats, down jackets, short and long styles…

Shoes, bags, mobile phones, and even makeup...

Everyone is different and is an independent existence!

"Okay, I was stunned for this day." Ju Hongfei sighed when he got in the car and drove back to the courtyard.

But this was not over. The next day, they went to the sky bridge to work on time, and continued to observe the expressions, facial features, and behavior of various people for a long time to judge who these people were...

I don’t know how many days have passed, but when the three of them went downstairs to prepare to go to work at the overpass again, Old Man Qin appeared. Looking at the three people who were practicing in the cold wind these days, the old man smiled.

"Okay, I don't have to go out today," the old man smiled, "Let's go, follow me to the fourth floor."

The three of them looked at each other, but they didn't know what the old man was selling, but they had to follow him upstairs.

This is a conference room. When the four of them walked in, the projector started working without the old man's instructions.

Photos after photo appear on the big screen.

"Stop." The old man looked at them, "What are the characteristics of these people?"

"The skin is darker, which is different from normal people." Ju Hongfei said.

"The eyes seemed dull," Maslow said.

"The skin is black and yellow, and the expression seems to be relatively dull." Jiang Xiaobai added.

"Well, it seems that these days have not been practiced in vain. You have also seen who these are!" The old man smiled, "There are many ulcers in feet, legs or arms without obvious reasons. This is usually the sucking of heroin, methamphetamine, etc., and the teeth rot or fall off without cause. This is a common situation of cough water addiction."

"Single-free, yawning or drowsy, these are heroin symptoms. People who are addicted to methamphetamine look more excited. People who eat ketamine have yellow skin and black skin..."

"If you are a person who often uses K or sucks K powder, because you often use nasal suction, you may have nasal mucosa congestion, nasal septum ulcers and even perforation caused by mucosal infection..."

"The most important thing is," people who have been taking drugs for a long time will gradually collapse the body's functions, such as poisonous sores, teeth falling off, nose collapse, and pale faces. At the same time, they will show mental dementia, slow reactions, and sometimes logical confusion. Especially, addicts with new drugs often have psychological problems such as inferiority complex, phobia, and other psychological problems. When you look directly at him, he will avoid your eyes and even be afraid."

The old man was very talkative, and the few people were terrified when they heard it. Qin Guanlan looked at them proudly, "Okay, you've finished this day in your studies. Here's the assessment."

Assessment? The three were stunned.

"Yes, it will be decided whether you will stay here through the assessment." Qin Guanlan smiled, "How is it, are you confident?"
