The rock explosion experiment was soon over.

Although Cassie's hands were shaking a little due to excitement, with the assistance of Floros, his experiment did not have any problems. Facts have proved that he has indeed invented a new type of black powder with a relatively more reasonable ratio and stronger explosive performance. This kind of gunpowder is not only used as a propellant or explosive material for grenades, but can even be used to dig mountains... Of course, it is also more dangerous. If it is transported and used in a safe environment, this relatively more potent black powder can more efficiently drill rocks and extract rocks, and mine metal ore and open-pit coal mines at high speed, making up for the lack of steam engines. Charles immediately gave Casse a title of knighthood, and gave him a piece of manor and a hundred gold coins as a prize, promising to promote him to a university student in the selection at the end of the year. For An Dang and An Dang's teachers, Charles also gave them a reward of 80 gold and a salary increase. "Has black powder been developed so quickly? This also made Charles a little emotional. Because Charles does not have any particularly good metal sealing technology, it would take too long for him to develop guns from scratch. In other words, That is to say, the development of cast iron technology has hindered the application prospects of the new gunpowder. Therefore, the gunpowder made by Charles is easier to store. The explosive performance is relatively not so strong. The formula he gave is four parts of saltpeter, one part of sulfur, A portion of carbon, that is, nitrate with a ratio of 66%, has just exceeded the detonation line. From this ratio, until the ratio of 71.4%, the explosive performance will gradually increase.

Seventy-six of China's standard "one nitrate, two sulfonate and three charcoal" formulas are very close to the optimal ratio of 15:2:3. And Kasai's mistake is actually very simple. In fact, this is very similar to the formula given by Mao Yuanyi, a Confucian general in the Ming Dynasty who was a "scholar under the banner and a general on horseback". It is already a well-formed blasting gunpowder.

But the danger of this kind of gunpowder will also increase exponentially in the process of preparation, transportation and use. However, it is also a good thing. Charles took a deep breath. This would allow him to add an extra chapter to his book—to the alchemy work he planned to add Kasser's name and inventions. He then opened his mission and took a look.

[Mission Task 5: Leave the handed down signed works on alchemy, breeding, mathematics, astronomy, optics, navigation, and the art of kings (6/7)]

Now. What he has not yet written is only the book on alchemy. After he conquered Persia, he wrote four books on mathematics, breeding, astronomy and the art of kings in less than half a year. This is the knowledge he has learned and mastered in the first place, and it only takes a little effort to organize it into a system. Among them, the breeding studies used some detailed data obtained by breeding "Solomon Horse" when he was King Solomon. He had already recorded it on the papyrus at that time, and there was a backup of the corresponding data at Baimeng, so he only needed to call it. And astronomy is the knowledge he mastered when he first came into contact with Raziel's book. It can be said that astronomy is the subject with the most written records besides history. After these two were also written, Charles came to gothic folk. Learn from several famous captains, combining his knowledge of astronomy and engineering. Wrote a book covering everything from material selection to shipbuilding to ship specifications and key points of navigation. As for optics, Charles used the work of Hassan, Uldi, and Roger. Just as he wrote Morris's name and his research in the mathematics paper. He also recorded the names of several of his optical masters in this book. The last remaining book is Alchemy. It was also the one that bothered Charles the most. It’s not because it’s so difficult for him to write—on the contrary, in this age before chemistry was born, it’s really easy for him to fool the ancients. Even if supernatural powers do exist in this world, the demon gods around him are the most authoritative masters in this regard. It can be said. For the subject of alchemy. No one in this world understands better than Charles.

But it was also because of this that Charles hesitated.

He wondered what the people of the world would think of this discipline. For pharmaceuticals, smelting, extraction, replacement and other projects, as well as all operations related to spiritual energy, how will people integrate it into their lives.

He can be said to be the person who knows alchemy the most in this world, and he can also be said to be the person who doesn't understand it the least. For his view of alchemy is not one, but completely separate. Many of his views are anachronistic, unsubstantiated, and counterintuitive. He directly pulls out a complete and perfect system, and people will inevitably rely on this system immediately, thus losing most of their abilities of self-questioning, self-reflection, and self-evolution. This can indeed form a better scientific and technological system in a short period of time... but it cannot cultivate a scientific spirit that can be passed down from generation to generation. After hesitating for a long time, Charles still decided that the three books, "Alchemy", "Astronomy", and "The Art of Kings", only expounded, not proved; they only wrote scriptures. Do not raise. As for how future generations treat this material and how to analyze and classify it in light of social reality, that is the business of future generations. He has already decided...From the next life onwards, he will no longer rule a certain country on the earth as a king, and let them conquer each other on the earth. With the development of the times, the increasing shortage of resources and the development of science and technology, he can no longer do so many "regardless of nationalities" common interests.

If he is a king, his position and strong sense of responsibility must require him to take a stand and work for the welfare of the people. And this position will start to be premised on harming the interests of other countries, which contradicts his ultimate goal of turning human beings into "golden species". So Charles decided that it is better to let the demon **** influence the rulers who control the kingdoms, and try to control the scale of the war as much as possible. He will have the freedom and abundant resources to concentrate on studying knowledge.

Casser is not the only academic he has personally approached. In the book "Alchemy", he recorded 31 inventions of a total of 17 scholars, as well as detailed formulas, design drawings and various data of finished products, leaving only a few discussions on ideas . For example, "experiment is the only criterion for testing truth" and the definitions of variables and constants, etc.

He is in the book The Art of Kings. Hidden a sentence in his heart: "Socrates once said, using a ridiculous metaphor, I am like a gadfly, stinging you all day long, trying to wake you up, persuade you, and accuse you."

This is actually the biggest feeling of Charles. Charles was starting to feel a little tired.

But he knows that he can't be tired yet—he doesn't have the power and leisure to be tired.
