Wearing a mask, fall into pure love

It was night that Chi Yi sneaked into the factory office.

He first connected WiFi, copied the computers of a group of factory managers, including manager Chang, one by one, and then transmitted them to musk fir villa thousands of miles away through countless network springboards. Then, open the data cabinet and look for the data one by one.

Although he didn't hold much hope for this office, he had to do all the screening work.

However, Cha guicha, what he was thinking was the blue plastic buckets he saw in the afternoon.

Since it is highly toxic industrial waste, how can it be transported casually by an ordinary truck? Also stacked in an area accessible to everyone?

Moreover, it is reasonable to say that the waste from the production of chemical agents in this chemical plant should be liquid. Why are there powder residues on those plastic barrels?

These are very suspicious.

Just as he was almost finished with the work at hand, the sound of the truck starting came out of the window.

He went to the window and saw a truck driving towards the back door of the factory.

Delivery so late?

A feeling crossed his mind: could it be those blue plastic buckets?

Chi Yi restored everything in the office and walked out of the office building.

First, he hid in the place where the street lights in the factory could not shine, and turned on the infrared detection function of his glasses.

After making sure there was no one around, he followed the shadow of the building, avoided the camera and came near the warehouse.

During the day, he found that cameras were installed around the warehouse.

Chi Yi opened the Signal Jammer built in his watch, waited for a while, determined that there was nothing moving around, quickly ran to the door of the warehouse, opened the chain and door lock, and went in.

The warehouse was dark, but it didn't affect Chi Yi's eyesight at all.

He went to the place where the plastic buckets were stacked during the day. At the moment, it was empty.

Chi Yi thought to himself: it seems that they let the driver take them away.

He squatted down and looked at the ground carefully. He found that the ground was cleaned very clean. It seemed that he had just dragged it with a mop. It was still wet and smelled of rot.

Finally, he found a little residual white powder at the foot of the wall.

He took out the key from his pocket, took out the pocket soft brush and evidence bag hidden in the key chain, and carefully collected the white powder. Then he left the warehouse and came to the factory laboratory.

Because the amount of powder extracted was very small, and Chi Yi had guessed what it was according to the physical properties of the powder, he directly skipped the stage of filtering impurities and started the identification experiment.

As expected, the laboratory has all the materials needed for the identification experiment.

Watching the solution in the test tube change from the original blue purple to purplish red and blue stratification, Chi Yi strengthened his judgment: this white powder is ephedrine hydrochloride!

remarks:

1. You can change your own physical location through the network springboard.

2. Ephedrine hydrochloride is a white acicular crystal or crystalline powder. It is an important raw material for the manufacture of methamphetamine and has been included in the management of precursor chemicals. Ephedrine hydrochloride can be detected by biuret reaction. The specific method is to take about 10mg of this product, dissolve it with 1ml of water, add 2 drops of copper sulfate test solution and 1ml of 20% sodium hydroxide solution, which will show blue purple; Add 1ml of ether, shake it and place it. The ether layer will turn purple red and the water layer will turn blue.
