For a moment, Jiang Yucheng almost suspected that his attack had not worked—a black shadow swooped up, filling his field of vision, and he was almost slumped on the ground in fright. Pen Fun Pavilion wWw. ｂiquge。 infoBut this guy only endured it for less than a second, and then he began to lose his balance and howl: After all, chemicals are not bullets, and it is impossible to stop anything, but as soon as the irritation of the skin and cornea begins to occur, the pain and redness will become more and more intense, and eventually the person will lose the ability to move...

"Whew!!!!!!!"

It was a little late, but the "chemical weapons" finally worked—the guy covered his eyes and let out a pig-killing howl. The berserker-like style that he continued to advance under my "fire suppression" just now was just an illusion of the inertia of his body moving forward - after "being blinded", this guy quickly lost his balance and fell to the ground.

"Whew, hit?"

Jiang Yucheng glanced at the red spout wash bottle with the word "dichloride" on it in his hand - now Jiang Yucheng was wearing rubber gloves, but he knew that the sweat inside the gloves should have been flooded long ago. Just now, he knocked out most of the bottles of "ammunition" in one go, and now the air around him is filled with a smell that is far more pungent than the anti-wolf spray...

Bottle washing is a kind of equipment used in the laboratory, is a kind of container commonly used to fill water or other liquids, and the top of the bottle washing is equipped with a water pipe type water outlet device. The most commonly used bottle washing is the extrusion type, which consists of a plastic bottle washing device consisting of a water outlet pipe - this is the kind that Lao Xu's laboratory is equipped with.

The container made of plastic, which has a capacity of 500 mL, is also very airtight - if squeezed hard, it can form a column of water with considerable water pressure - hence the name "bottle wash", because the experimenter often uses the water pressure of this column of water to clean the stubborn stains in the container. To put it simply, with this kind of thing, you can shoot out the water column like a child's water gun.

As mentioned earlier, one of the most important uses of the bottle is to clean the reaction vessel – and in Lao Xu's laboratory, in addition to emulsifiers such as laundry detergent, other organic solvents are used for cleaning. The most commonly used solvent is ethanol, but usually, in addition to physical cleaning with a test tube brush, a more powerful liquid called "dichloride" is used to deal with stubborn stains, which is the "ammunition" used by Jiang Yucheng.

The so-called "dichloro" is actually the abbreviation of dichloromethane - dichloromethane, DiChloroMethane, commonly known as DCM. The molecular formula is CH2Cl2, which is a disubstituted alkane with a very simple structure. As a non-flammable organic solvent with a low boiling point, it is often used to replace petroleum ether and Acetone as solvents. Compared to mild, harmless solvents such as ethanol, this thing is really hard to serve...

When it comes to the medicines that can be taken out of the chemical laboratory and can be used as weapons, the first thing that comes to many people's minds is definitely hydrochloric acid, sulfuric acid, and nitric acid, which are the three major inorganic strong acids -- especially the concentrated sulfuric acid that has been broken by countless phases, and "even a bear can be broken to show you!".

However, although these weapons of mass destruction look fierce, they are not so easy to use in reality - on the one hand, these things are extremely dangerous one by one, and they must be carefully served, and they are not suitable for use as weapons - because they are not robust enough, if you kill a thousand enemies and lose eight hundred, it will be really a cup. On the other hand, an important characteristic of the discipline of chemistry is that "interlacing is like separating mountains" -- more than 95% of different research directions, from theoretical systems to experimental equipment and medicines, are different. In other words, the above famous killers, organic laboratories actually do not have...

In the organic laboratory, the most capable anti-wolf weapon is actually the one used by Jiang Yucheng, CH2Cl2, dichloromethane DCM.

As for this kind of thing, there is nothing particularly corrosive, and it is not very toxic, and it is harmless to humans and animals compared to the above-mentioned large-scale killing weapons - but on the other hand, this thing must be used with caution, because it has a strong irritation. Jiang Yucheng remembered that when he first entered the laboratory, he didn't take his senior sister's reminder seriously, and was touched by this thing on the back of his hand (he was wearing rubber gloves at the time). In the blink of an eye, the back of his hand turned red and ached hotly - of course, with no serious consequences, and the redness subsided that night.

The anti-wolf spray used by the girl didn't work - Jiang Yucheng estimated that the guy was wearing a hood, and the anti-wolf spray didn't hit the eye with a single blow. But the weapon in Jiang Yucheng's hand is different - the penetration ability of DCM is very strong, according to national regulations, in the high-risk environment that needs to be protected, it is necessary to wear special anti-penetration overalls to defend DCM. When Jiang Yucheng first touched it, he wore protective gloves made of rubber on his hands, but the back of his hands were still burned red. Now this guy is only wearing a hood that is full of loopholes in Jiang Yucheng's opinion, how can he resist the weapon in his hand?

Moreover, this wash bottle has a capacity of up to 500mL, and if you miss a hit, you can continue to attack, and you can even shoot continuously for a long time. If the anti-wolf spray in the girl's hand is a pistol, then the wash bottle in Jiang Yucheng's hand is a real assault rifle - the penetration and fire durability are far stronger than the pistol.

I saw this guy fall to the ground, covering his eyes with his hands and howling and rolling - this guy was wearing a hood, and he couldn't see the appearance of his face clearly, but the back of his hand was swollen and shiny. Out of caution, Jiang Yucheng still decided, now is not the time to relax, go up and make up for the knife.

"Hiss~~~~"

Jiang Yucheng was just about to take a step, but his injured right foot suddenly lost his strength, and the whole person was about to fall forward - fortunately, he grasped the center of gravity in time and did not fall and eat. However, he also knelt on one knee, and it hurt to knock, and the weapon in his hand was not held steady, and he almost slipped over.

Just when Jiang Yucheng fell, the victim girl looked at him with strange eyes, and made a sound of "Woo~~~~" - It seems that because her eyes have adapted to the darkness, Jiang Yucheng finally saw her appearance clearly by the light of the street lamp: it was a girl who was less than one meter five tall and petite like a primary school student, wearing a white T-shirt with a blue short tie on her upper body, a blue miniskirt on her lower body, and black and white striped stockings wrapped around her slender legs. Although it is a good pair of legs, it is still a little worse than Xiao Qi - Jiang Yucheng gave such an evaluation in his heart...

By the way, the girl's hands have been behind her back - probably shackled by restraint devices such as erotic handcuffs, and the delicate and small mouth is forcibly stretched open by a white plastic gag ball larger than the baby's fist, and obvious reflections can be seen at the corners of the mouth under the street lamp - it should be saliva forced to flow out, and it looks like shame - the girl's upper body is torn apart, the corset is torn, and the large white skin exposed on the chest has turned bright red for some reason. Nine times out of ten, it was sprinkled by the DCM that Jiang Yucheng "strafed" just now. As for the boobs...

This guy is not only a scumbag, but also a pervert out of ten... But now Jiang Yucheng doesn't have the leisure to appreciate the spring of little Lori - his ankle injury is not healed, but he was hit by an arrow in his knee, and it seems that his road to righteousness and courage is also full of ups and downs... However, now that the victory is in hand, these small pains do not affect his confidence - seeing that the other party is still rolling there, Jiang Yucheng has more room for ridicule:

"♂ Aha, ♂ Yi Jianlian, ♂ Yi Jianlian, ♂ Yi Jianlian?!" ♂

Somehow, what popped out of his head were the lines of these philosophical ♂ videos, seeing that the guy was still calling and ignoring himself, Jiang Yucheng decided to let him taste it-

Jiang Yucheng once again lifted the wash bottle and aimed at the white briefs from which he had taken off his outer pants - more precisely, the banana ♂ under his crotch...

♂ "Take♂it♂boy!"

"呲・・・・・" Let you taste our improved true god の救♂ ji!

"♂ Ah ♂!!!!!h

If the cry just now was miserable, then this time it was already a non-human scream - Jiang Yucheng knew that he must be eager to swing his knife from the palace now, cut off the words, and be a man without weaknesses ♂...

Note 1: Regarding concentrated sulfuric acid, several black bears in the Wudaokou ** Silk Bear Incident were splashed with sulfuric acid, and the other few were splashed with caustic soda...

Regarding hydrofluoric acid, although this thing is a weak acid, the harm should not be underestimated - you can Baidu Baidu "Langxi Middle School Student Hydrofluoric Acid Poisoning Incident" by yourself, hoping that no one of the victimized students needs to have their limbs amputated...

Triethyl aluminum is an initiator used in polymer chemistry laboratories. At the same time, it is also an incendiary agent used by the US military M202A1 incendiary rockets. The substance is often used to enforce the law of divine judgment when the FFF group tries suspects - rest assured, if you do keep your virginity and do not betray the organization, even such a strong incendiary will not have any effect on the innocent members...

PS: According to the results of my physical experiments, the lethality of DCM is actually not as exaggerated as written in the article, of course, it's okay to have a paste... By the way, the protection standard for DCM comes from Du Niang Encyclopedia, and the rubber glove protection is broken down is my own real experience.

PS2: Seemingly ordinary rubber gloves can't resist organic solvents...
