Following Jiang Feng, the two returned to Fielding's temporary workshop again.

Sulfur, saltpeter, charcoal, these things can be found in Fielding's makeshift workshop. After Jiang Feng removed these items from the display shelf, he laid them out side by side and placed them on the wooden table that Fielding had used to study the puppets earlier.

Looking at the materials on the table, Fielding was slightly stunned.

In the alchemical recipe he was familiar with, he had never seen sulfur and saltpeter put together. Both of them are more toxic herbs, and only when some potions are prepared, a small amount of them will be put into them, but the two ingredients are rarely added to the same cauldron.

And charcoal.

He didn't know why charcoal was here too.

Even to heat things, he usually uses candles with a stable flame output that makes it easy to control the temperature, rather than charcoal, which takes a lot of effort to ignite.

Jiang Feng turned to look at Fielding.

For his part, Fielding did not intend to train him to become a craftsman. With his potential, he has every chance to become the founder of the world's natural science, create a general theory of inscription technology, and become the founder of a school or theory similar to Lao Tzu, Archimedes, and Turing in the history of the Federation.

If you want to solve the threat of chaos at the root, one of the best ways is to use materialism. The means of the righteous eliminate ignorance, and the other is to eliminate the advantages of mystical forces in primitive civilized society. Just imagine, when a cheap bullet has the same power as the spell of an inferior wizard apprentice, will the position of a wizard apprentice in Boulder City be so transcendent?

The answer, of course, is yes.

But certainly not as detached as it is now.

Jiang Feng thought for a moment before he spoke, "Fielding, I know you must be curious why just these three ordinary things are so powerful. ”

"Yes, sir." "In alchemy, sulfur and saltpeter are cheap and common alchemical materials, but we rarely put them together. And charcoal, which we rarely even use, except for poor alchemy apprentices. ”

"It's a prejudice that anything that seems small, if used in the right way, can unleash power beyond our imagination. The root of this power does not have to come from the magic of the mystical side, but it can also come from the power that can be found everywhere in our lives. After a pause, Jiang Feng continued, "Compared to witchcraft, I prefer to separate it into a separate category and call it a natural science. ”

"Nature...... Science? ”

"That's right." Jiang Feng nodded, "There are many branches in natural science, and what I want to tell you about is chemistry. ”

This statement is inaccurate in federal textbooks, but it is the most intuitive expression for the aborigines, because there are many things that cannot be seen at all with their vision, and when they can see it, they will naturally refine their theories. Instilling advanced things in them too early will only mislead people's children.

"Take gunpowder, for example, in the perception of wizards, the root of all witchcraft is the permutation and combination of magical elements. And I, extending this theory, after countless experiments, can learn that not only witchcraft, but also everything in the world, you and I standing here are made of tiny elemental particles. ”

"How is this possible!" Fielding exclaimed,

"Everything is possible," Jiang Feng was expressionless and continued to ask rhetorically, "What is blood?" ”

“…… Water? ”

"What is meat?"

"Is this ......," Fielding was asked.

Meat? Isn't it just meat?

"What happens after the meat is burned?" Jiang Feng prompted.

A flash of inspiration flashed through Fielding's mind, and he blurted out.

"Carbon!"

"That's right," Jiang Feng nodded, "Then let me ask you again, what are you?" ”

“…… Water and carbon? Fielding's pupils dilated.

In his mind, it was as if a door had opened.

Behind this door was a world he had never seen or imagined.

Man is made up of water and carbon.

Water and carbon ......

"Water and carbon are just basic substances, and if we break it down step by step, we will find that in addition to water and carbon, there are many other subtle elements that make up our body. For example, the blood smells of iron because it contains iron, and phosphorus fires float on the graves sprinkled with ashes, because phosphorus is also a component of the human body. Each element can be represented by a single symbol, such as in the three cheap alchemy materials in front of you......"

Jiang Feng stretched out his hand and pointed to the table and continued,

“…… Sulfur and charcoal, there is a single element in them, and I use C and S to represent them. ”

"What about saltpeter?" Fielding asked hesitantly.

"It's the product of an element and a combination of elements, and there are three elements in it: K, N, and O." As he spoke, Jiang Feng wrote down the three symbols, and finally wrote down the basic molecular formula of saltpeter, "Then, this is their combination, and the number in the lower right corner is the ratio between them." ”

“…… This, this is just amazing. ”

Fielding's eyes widened in disbelief as he stared at the three things on the table.

"So, now that you have a preliminary understanding of the elements I'm talking about, you should be able to understand what I'm going to say next." Jiang Feng said.

Fielding swallowed and nodded, waiting for Jiang Feng to continue speaking.

Jiang Feng nodded when he heard this, and then said, "Any reaction will release or absorb energy, some violently, and some are not easy to detect. Black powder, on the other hand, uses this principle to complete the reaction in an instant and release a huge amount of energy at the same time. Again, this reaction can be expressed by a formula, like this......"

As he spoke, Jiang Feng picked up the charcoal, wrote a formula on the board, and around this formula, he explained the recipe for making black powder, the precautions during production, and the utensils that need to be used.

Because this thing is still dangerous to synthesize, he spoke in great detail, and Fielding listened very carefully.

After saying the last point, he threw the charcoal on the table, and Jiang Feng clapped his hands.

“…… Do you understand? ”

Fielding didn't really understand it, after all, it was a completely new thing, but he already understood the making and principle of black powder, and it was not difficult for him to make black powder.

"I understand a little, a lot of it still needs to be digested, but it won't be too difficult to make." Fielding said truthfully, then hesitated for a moment and continued: "My lord, I have an idea for you, according to your theory, since the three elements can condense a saltpeter, can the inscriptions be combined. ”

Jiang Feng was a little surprised when he heard this, even he didn't expect Fielding to think of this question from saltpeter.

But it's an interesting idea.

"It's up to you to figure it out. The only thing I can tell you is that experimentation is the only criterion for testing truth. ”

Touched in his heart, Fielding's eyes lit up with a fiery light, he took a deep breath and bowed his head.

"Thank you for your teachings."

"That's all I have to teach you," Jiang Feng nodded with satisfaction, and then said: "In addition, I want you to focus on your own research, as for the problem of gunpowder, you can find other people to help, this is not too tedious work, but you need to ensure the quality of gunpowder, which is related to the lives of many people." ”

Fielding was slightly stunned when he heard this, Jiang Feng didn't need to say anything about the quality, he would also strictly control it, and he was more concerned about another thing.

"My lord, are you going to build an alchemy workshop?"

Jiang Feng nodded, he did have this plan, whether it was now or in the future, the alchemy workshop was indispensable, of course, some confidential things were still done in the research institute, but this alchemy workshop could help the research institute share some things that were not particularly important. The relationship between the two is like that between vocational schools and universities, one cultivates applied talents, and the other cultivates research talents. The former uses technology, and the latter digests the techniques taught by Jiang Feng.

"That's right, we'll be here for a while, and I'll leave this matter to you. Apprentices could be selected from among the common people, preferably those from poor families, young age, and easy to control. The technology of gunpowder is not yet suitable for disclosure, and I need you to assure you that these secrets stop at the alchemy workshop. Jiang Feng said to Fielding.

"Guaranteed to complete the mission!" Fielding said solemnly.

Jiang Feng didn't need to say much about these at all, he had seen the earth-shaking power, and he naturally knew that this thing had to be strictly kept secret.

"If you want to budget, you can go to the town hall's account, and you can go to Rembert in a while, and I'll say hello to him."

"Yes, sir."

Fielding nodded when he heard this, and then left the city hall, the establishment of the alchemy workshop must have a large enough place, and this location is also a troublesome matter, but fortunately, Jiang Feng has enough funds to support him to dispose of.
