Hg, also known as mercury, is an accumulating persistent poison that is often found in electronics.

It is used in many experimental projects.

Among them, mercury oxide, mercuric arsenide, mercury benzoate, mercury phosphate, mercury salicylate and red mercury have a wide range of medical applications.

Moreover, in ancient China, mercury was also a kind of surgical medicine.

In 1973, the "Fifty-two Prescriptions" in the silk book unearthed from the Mawangdui Han Tomb in Changsha had four prescriptions that used mercury.

When Qi Huan was buried in Linzi, there was also a saying in his tomb that "pouring mercury into a pool".

In the pre-Qin period, the ancient Chinese people obtained mercury by heating cinnabar, that is, mercury sulfide powder.

It is no exaggeration to say that the history of mercury and its compounds has spanned almost the entire history of Eastern and Western civilizations.

As a hazardous chemical.

If a private person buys more than 5,000 grams at a time, he or she needs to file with the local public security organ.

Units or production departments need to hold relevant permission certificates for hazardous chemicals when purchasing.

But it doesn't matter if it's a small batch for individuals, it's easy to buy it at chemical reagent stores everywhere.

Chen Xuan had already known about this, so his goal was clear.

The mobile navigation app quickly retrieved more than a dozen reagent stores.

He made a selection, mainly considering the distance factor, and chose a chemical reagent store called: Taixingan Medical Equipment Co., Ltd. as the destination.

A variety of chemical reagents are sold there, including nucleotide reagents, sodium iodide reagents, glutastein biochemical reagents, and gold basidiosin A chemical reagents.

The variety is relatively complete, and basically the biochemical and chemical reagents that are allowed to be sold in small quantities on the market can be bought.

After determining the location, Chen Xuan stepped out of the house after getting dressed neatly.

The time has come to 7:43 in the morning, which is the morning rush hour to get to work.

As soon as he pushed open and locked the door, a shadow hurried down from the upper floor.

The high-top boots stamped on the stairs with an exceptionally crisp sound.

Chen Xuan turned around and looked at the staircase.

Coming downstairs in a hurry was one of his "neighbors" who nodded his head.

Qianying's owner is named Lin Qiang, who is two years older than him, and works in Tianhai's local Lianjia and is a real estate agent.

When he looked up, he just saw the long black silk legs.

She wears a black chain uniform, and every step can outline a full curve.

This age is the time for women to show their beauty and marvel at time.

Chen Xuan glanced at it, his gaze paused, and he calmly showed an expression of appreciation.

In the past, he didn't dare to think about it, in Tianhai City, beautiful women are also a scarce commodity, not something that ordinary people can touch.

Previously, he had seen Lin Qiang's back in and out of luxury cars at the gate of the community more than once after working overtime.

This is an ambitious, intelligent woman who is searching for her prey in this big city.

When the two of them passed shoulders, she raised her head and looked at Chen Xuan, her eyebrows and eyes were curved like the moon, she smiled and said hello.

"Good morning! I'm running late! ”

When Chen Xuan heard this, he also smiled and nodded.

"Morning, pay attention to the steps."

Lin Qiang's long, smooth black hair was tied into a high ponytail, and her pretty face was slightly covered with light makeup, and her thin lips were slightly raised.

I wonder if she's a hunter or a prey?

The two didn't communicate anymore, she strode downstairs to her post, and Chen Xuan also put away her admiring gaze.

Now he doesn't need to look up to this kind of woman.

He has a whole otherworld to develop and claim.

There are also cute and petite cat girls and pure and beautiful half-elf misses.

This vulgar blue star, after all, failed to tie his fate.

Chen Xuan smiled as if he was emotional, and calmly went downstairs.

……

Half an hour later, Chen Xuan walked out of the chemical reagent store.

He carried a plastic box in his hand.

Inside the box are six plastic cans made of PP with a weight of 350 grams.

Each jar contains mercury of 99% purity.

It is worth mentioning that 1 milliliter of mercury is equal to 13.6 grams, so the nominal unit of measurement is usually grams.

It's not cheap, the purity the more expensive.

There is also mercury with a purity of 80%~85% and a small amount of sulfide as a stabilizer.

Chen Xuan directly filled it up and arranged a high allocation.

According to the market price of 925 yuan per 1000 grams on the same day, it is converted into 0.925 yuan per gram.

This price is much more expensive than the international mercury price, and is equivalent to the difference between the international gold price and the actual commodity gold price.

He bought a total of 2,100 grams and paid 1,942.5 yuan for it.

This investment needs to be recouped through the Naroa Continent.

At present, he can only get through the otherworldly link first, so that he can continue to feed back to Blue Star.

He also has an eyebrow for Naroa to sell Blue Star's items, and he needs a certain amount of capital and foundation to be able to play, and he also has requirements for his personal strength.

But as long as the stall is spread, Blue Star's side can definitely be described as making money every day.

At that time, the commercial cycle between the two worlds will be initially formed.

Chen Xuan will become the only meeting point and enjoy the most dividends!

……

Travel through the vast city.

Over the next six or seven hours, he completed all the procurement projects one after another.

Include:

Ten permanent brand 28-inch weighted bicycles, because they are purchased from physical stores, the unit price of each has reached 680 yuan, and the cost is 6,800 yuan.

If it can be purchased in large quantities, or through the procurement network, the unit price cost can be reduced by more than 15%.

But it doesn't matter, anyway, this batch was brought to the other world to test the water first.

In addition, there are two fully automatic cola commercial machines.

The price of a single unit is 3700 yuan, and two gas cylinders are included.

He also purchased 20 10L carbon dioxide cylinders for 280 yuan each

50 boxes of 20L concentrated cola syrup, 155 yuan per box.

This thing is mixed 1:5 with clean water, and then filled with carbon dioxide, and it becomes a cola drink.

The inflation will be done by the machine, a fool to install and operate.

Just to solve the power supply problem, Chen Xuan spent more than 4,000 yuan to buy a set of 15 kilowatt split diesel generators, the same type of diesel head and tractor.

Then I went to the gas station and bought a few barrels of diesel, which is more convenient than gasoline that needs to be certified to be bulk loaded.

After buying all these things, he took them all to the secret place and put them in the storage compartment.

Finally, I went to the suburban aluminum factory and purchased 50 high-purity die-casting aluminum ingots with a standard weight of 10KG and 99.99%.

The price of aluminum is 18,630 yuan/ton, and the casting material is more expensive.

Chen Xuan's half-ton aluminum ingot also cost more than 10,000 yuan.

In fact, half a ton of aluminum is not enough for the daily consumption of those township-level aluminum alloy factories.

This level of apheresis can be described as a small order like a cow's hair.

The handover process is very convenient.

Chen Xuan also gave money neatly, and the warehouse was single, and as soon as the invoice was opened, the warehouse shipped on demand.

It's just that the factory doesn't package delivery, Chen Xuan called a micro-cargo and pulled it to the designated secluded place and it was over.

All in all, this round of procurement went relatively smoothly.

It's just that the money is really not spent.

In just one morning, Xiao 40,000 was smashed out.

This further shrank his remaining savings.

But it's all worth it!
