Four days later, in the small courtyard of Bong'en Street

Compared with the small courtyard that was clean and tidy four days ago, with all kinds of exotic flowers and plants, the small courtyard now is more of a factory than a yard.

I saw that in this small courtyard, all the courtyard walls and shadow walls were pushed to the ground, and the flowers, vegetables and fruits planted were also pulled clean, and there were strange or transparent or brown glass products on the ground, some of which existed independently of each other, and some of them were integrated, and the most eye-catching thing was the two copper discs with a diameter of two meters placed on the side of the courtyard, and two huge black pieces were tied to both sides At this time, two copper wires wrapped in red paint were connected to it, and they extended to the bottom of a strange glass instrument.

At the same time, the courtyard was also filled with a large amount of spirits, wrapped sulfur, and a large pile of salt, of course, some coke and other auxiliary products Tang Jin had already prepared a large pile.

"Shizi, we have collected everything we can collect here, take a look...... Is it enough? Qin Hai took a list with the total number of items recorded and handed it to Tang Jin. Tang Jin didn't look at it, and pushed away the list in the other party's hand. It didn't matter how many things they collected, even if the amount was not enough, Tang Jin wouldn't give them more time.

Moreover, he does not know the exact number of the enemy, but has a vague concept of "thousands of people", and these thousands of people can be three or four thousand, or eight or nine thousand, and there is a huge difference in the middle. There is a good saying, "All weapon calculations that do not know the number of enemies are hooligans." ”

Now if he wants to deal with this situation, the only thing Tang Jin can do is to make as much as possible, rather than have more than less, which is also the reason why he let Qin Hai and the others frantically collect materials at the beginning.

As for what he's going to do...... It's easy to say, it's hard to say it's difficult, of course, more people describe it as "terrifying" and "cruel", which is mustard gas.

Mustard gas, mustard gas, scientific name dichlorodiethyl sulfide, also known as mustard gas, is a liquid poison that emits harmful gases, and is an erosive agent in chemical weapons. It was a military weapon invented and used by Germany during World War II, and of course its most famous and frenzied user was...... An island nation.

On the one hand, it is because it is highly toxic and has no effective treatment, and on the other hand, the raw materials are easy to obtain and easy to make, compared to other weapons of mass destruction, its preparation process is much simpler, and it can be obtained in a short period of time even in the current era.

Its three main raw materials, sulfur, green gas, ethylene. Of the three, sulfur is the most readily available, and the ready-made sulfur is; Green gas is a little more troublesome, but it can also be obtained by electrolysis of sodium chloride, which is also known as salt; As for ethylene, it is the most difficult of the three, although fruits and seeds will emit a small amount of ethylene, but the amount is too small, and it cannot meet Tang Jin's needs at all, but fortunately, he thought of another way, concentrated sulfuric acid can be added to alcohol to get ethylene, as for where does the alcohol come from...... Isn't there wine? Distillation is it. If there is concentrated sulfuric acid, there is sulfur, make a sulfuric acid out, and then slowly purify it.

After thinking about it, I made some changes based on the actual situation, and basically formed the current situation.

Closed his eyes and thought about the whole process, and the next moment Tang Jin opened his eyes suddenly, staring at the people who had already prepared below, as well as a large number of hired people, and commanded.

"Qin Hai, you take someone to take all the liquor to me to distill, I will personally check the progress later, when I say stop before stopping; Feng Gu will take someone to light the fire first, I will personally direct you to burn the sulfur later, and the rest of Fang Xiaoer, you will command someone to fill the jar with water, pour the salt into it and melt it all, Su Mochun, you two sisters go and instruct the craftsman to check the core instrument again to make sure that there is no air leakage, otherwise once there is a trace of leakage later, all of us will definitely die. ”

One order after another was issued, and everyone in the courtyard immediately got busy, moving wine and turning salt, and among all the people, the Su Mochun sisters and the craftsmen they led were the most serious, and they checked inch by inch around the pile of so-called "core instruments", not letting go of any point, after all, Tang Jin had already said just now, but anyone who leaked a little bit of it would have to die...... No one wants to joke with their lives.

However, the busiest of all of them was not any of them, but Tang Jin, the master who gave orders. Not for anything else, just because all the processes of everyone present need him to supervise, one will have to check the progress of alcohol distillation, one will have to guide the combustion of sulfur, one will have to confirm whether the defects found on the instrument have any impact, piggyback and study the progress of each group, tell them when to open the valve, when to carry out the next step, and even Tang Jin has even used the body method, which barely caught up with all the progress.

"Feng Gu! Open the intake valve and use the bellows to send air inside. Tang Jin turned his head and glanced at the sulfur that Feng Gu and the others had already made, and asked him to open the intake valve in a timely manner, add air, and the sulfur burns to generate sulfur dioxide, and the sulfur dioxide is introduced into water to produce sulfurous acid, and the sulfurous acid is oxidized to produce sulfuric acid, and then the sulfuric acid is purified into concentrated sulfuric acid, and then ...... You need the alcohol from Qin Hai's side.

"Qin Hai, the progress on the alcohol side is slower, and it's not good here." Glancing at the progress of sulfuric acid, Tang Jin immediately frowned, and immediately slowed down the production of alcohol. The sulfurous acid has just been prepared, and the sulfuric acid has not yet been obtained, let alone purified concentrated sulfuric acid, and the alcohol side has some finished products because the process is relatively simple. This is not good, you must know that this thing is flammable, explosive and volatile, don't wait until the concentrated sulfuric acid on your side is not done well, and the alcohol over there will explode or volatilize first, and then it will be troublesome.

While slowing down the progress on Qin Hai's side, the salt water on Fang Xiaoer's side was almost melted, because Tang Jin directly showed his identity, the salt merchant almost emptied his family, Tang Jin's salt was not worried, and compared to other congratulations, there was really no technical content in turning a salt water, so Fang Xiaoer's side became the first to complete.

But Tang Jin just asked him to wait first, and did not rush to start the self-made generator to make green gas, firstly, the green gas is a toxic gas, and it is difficult for several people present to have to explain, and secondly, he did not have a container to store green gas, according to Tang Jin's original idea, green gas would be directly produced and directly entered the final stage, eliminating the intermediate storage stage.

In this way, under Tang Jin's crazy busyness, everything went according to plan. In the past four days, Tang Jin has rehearsed all the processes countless times in his mind, taking into account almost all possible problems, even if the situation on the scene is a little different from his original idea, but there is no problem overall.

For a while, this small courtyard was full of people, the fire was rising, and countless figures were busy shuttling through it, or moving wine, or adding firewood, or throwing pieces of sulfur into the fire, at first glance, it was extremely chaotic, but if you look closely, it feels orderly, like a factory, in fact, according to Tang Jin's conception, this is a factory, an otherworldly version of the factory, but compared to the glass factories, soap factories, or gun factories that the protagonist engaged in other crossings, Tang Jin not only has a large technological span, On a larger moral span.

After all, those soaps, glass, or something, at most, disrupt the market order, even if it is a musket, it only slightly increases the severity of the war, but Tang Jin is ...... It's simply a weapon for slaughter, to put it mildly, as long as Tang Jin is willing to produce it on a large scale, he can rely on this thing to conquer the whole world.

Of course, he wouldn't dare to do that, after all, this thing is an indiscriminate attack, if you are not careful, the enemy is not killed, and you will be happy if you play yourself to death first, not to mention that this thing is extremely toxic, and the whole world can basically be declared extinct after it is used up.
