"Pap" ...... "Papa"......

"Hurry up, you dog minion, do you think you were still a master? Now you are just a lowly minion, if you dare to be disobedient, Lao Tzu will not be able to beat you to death. ”

Early in the morning, the soldiers of the logistics department drove the slaves to build the ice wall, and one of the soldiers used a leather whip to beat a middle-aged Han man wearing a foreign costume who was slow-moving, and shouted.

The soldiers of the Black Armor Army are all bandits, not very civilized, and have a rough temper, and these former masters have been offended.

There are now more than 15,000 slaves on Changsheng Island, as far as the eye can see, like herding sheep, all over the mountains, far and near there are slow-moving slaves eating whips from time to time, and they are often some former old ladies and wives, the real Aha is very clever, they are used to being slaves, and they can't stand the whip.

This is called the cycle of cause and effect, retribution is unpleasant, and things in the world are so amazing that you never know when disaster will come.

As the saying goes, the superior has a word, the subordinates run and break their feet, Li Huaixuan was originally distributing the slaves' property, Yang Wenli's order, he immediately realized that building an ice wall is a major matter of life and death on Changsheng Island, so he immediately stopped the statistical work, and ordered his subordinates to drive the slaves to build the ice wall early the next morning.

Because the project is too vast, Yang Wenli simplified the scale of the ice wall, and built it as a jagged ice wall with a width of one meter and a height of three meters, and the length changes according to the terrain.

The troops were actively preparing for defense, and Yang Wenli was not idle, he led Wang Rucheng and several traitor scholars under Wang Rucheng to start developing explosives.

There are five of these scholars, they are selected by Wang Rucheng from more than 100 traitor scholars, they are proficient in arithmetic, and they like miscellaneous studies, and they are exactly the assistants that Wang Rucheng needs.

In the past, they were just the bookkeepers of the Tartar government and the officials' families, they didn't do much evil, and they had the qualifications to be reformed, and they could be promoted to commoners or people with their own ingenuity.

When he arrived at the workshop, Yang Wenli said to a few traitor scholars who followed him: "Listen, the task of several of you is to purify the gunpowder materials, potassium nitrate is enough for the time being, don't worry about it for now, the main thing is the purification of sulfur, as well as the burning of high-quality wood charcoal."

The charcoal must use good willow charcoal, which requires careful and meticulous protection of the purity of the charcoal and the absence of a trace of impurities.

Sulfur is insoluble in water, so it can only be distilled, and the yellow smoke produced by sulfur distillation is highly toxic, you have to find a way to make the distillation equipment not leak, and do not see water, because sulfur gas is soluble in water, it will become liquid acid, it is highly corrosive, and the jar that cools sulfur gas is cooled by ice and snow outside, and the specific structure is like this. ”

As he spoke, Yang Wenli squatted on the ground and drew a simple diagram of the equipment of the dry distillation cooling tower, explaining it to several of Wang Rucheng's assistants.

"In fact, our workers will do the work of burning wood charcoal, dry distillation and purification, but they don't understand the principle, the task of the few of you is to lead them to do this, and ensure the quality, responsible for purifying all the sulfur purchased from Dongying, and at the same time burning enough willow charcoal, burning it a thousand catties first, understand?" Yang Wenli got up and said again.

"Please rest assured, the minion understands." Several traitor scholars hurriedly knelt down and snorted in response. They used to do things for those Tartar masters, and they also had to talk back, and they called themselves slaves when they exited, but they were used to it.

"Hmmm! Go ahead! Yang Wenli nodded in response, and raised his hand again to let a few people do things.

After a few people left, Yang Wenli said to his scientific research assistant Wang Rucheng: "Rucheng, next I will take you to conduct a more dangerous chemical experiment, we will develop several very important chemical substances.

First of all, the most basic three acids and two alkalis, which are the basis of all chemistry, and the reason why I only arrange for them to purify the material is because I want to develop a new smokeless high explosive ......"

Wang Rucheng hurriedly took out a pen and paper to prepare a record and asked, "Great Commander, what are three acids and two alkalis?" ”

"The three acids are nitric acid, sulfuric acid, and hydrochloric acid, and the two alkalis are soda ash and caustic soda. These chemicals are the basis of all chemicals, and we use soda ash in firing glass, and glass is also a chemical substance, not a single element substance like gold, silver, copper, and iron. ”

Yang Wenli patiently explained to him that Wang Rucheng recorded these new nouns with a pen and used the word chemistry as a general outline, and he, a native of the late Ming Dynasty, began to come into contact with systematic modern chemical theories.

"Due to time constraints, we will only develop nitric acid and sulfuric acid for the time being, and you will first help me prepare the basic materials for experiments.

There are potassium nitrate, sulfur, dansha, cotton, alcohol, animal fat, and diatomaceous earth that I prepared earlier.

I'm going to assemble the glassware I fired some time ago. Yang Wenli began to work and casually ordered.

Because these chemical experiments are very dangerous, Yang Wenli only uses glassware for a small number of experiments to minimize the risk of explosion, and at the same time, he is only responsible for teaching Wang Rucheng these chemical theories, and he will not participate in the mass production in the future, which is too dangerous.

These experimental materials have been used by him before, so they are all prepared, for example, Dansha was purchased in small quantities when he developed the silver plating of telescopes before, and diatomaceous earth was specially dug by the sea after he came to Changsheng Island, and he had already considered that he might develop safety explosives in the future.

When Yang Wenli assembled the experimental table, Wang Rucheng also happened to bring all kinds of materials, only a little of each, and he brought it with both hands at one time.

Yang Wenli picked up a glass and filled the sulfur Wang Rucheng had brought, put it into a series of equipment that just happened to fit the glass, lit an alcohol lamp and heated it under the glass, and at the other end of the glass tube, he used a glass to hold half a glass of water, and the glass tube was inserted into the water.

After doing all this, he explained to Wang Rucheng: "We first try to make sulfuric acid, which is similar to the steps of purifying sulfur, but at the other end, I am inserting the pipe directly into the water to make sulfuric acid, remember, this water must be pure distilled water, not ordinary river water or spring water, because natural water always contains trace metal elements and other substances, which will react with sulfuric acid and make sulfuric acid impure." ”

Wang Rucheng hurriedly used a pen to record this key point of Yang Wenli's speech.

As Yang Wenli spoke, due to the heating of the alcohol lamp, yellow smoke was formed in the glass containing sulfur in a short time, and the smoke rose and entered the water of another glass through the glass tube on the integrated lid, producing a large number of bubbles and emitting a thick and pungent smell.
