Chapter 161 Alchemy and Chemistry

The principle and structure of the DC generator are very simple. When Roland was a child, he dismantled the motors of more than a dozen four-wheel drive vehicles, from ordinary whiteboard motors to the legendary Jin Chaoba, and even wound the rotor copper wires by himself. These motors are typical DC motors.

There is no difference in structure between a DC generator and a DC motor. In essence, they are the same thing, and their functions can be interchanged. As long as other machines drive the motor rotor to rotate and the wires cut the magnetic induction line continuously, the induced current will be continuously generated.

With the help of Mystery Moon and Anna, it only took half a day for Roland to assemble a simple DC motor. The stator part was all made of wood, and then handed over to Mystery Moon to impart magnetism. The commutator at the end of the rotor is embedded in a log with a hole in the center of the log, which can be connected to the shaft of the steam engine. Such a structure not only facilitates manufacture, but also ensures mutual insulation between the commutator segments.

As for the new steam engine, it became him and Mystery Moon watching Anna perform amazing processing skills. When large-scale parts need to be made, she spreads the black fire, wraps a pile of iron ingots like cloth, melts it and then shrinks the black fire, presses it into a plate that meets the size requirements, and finally cuts it into shape.

The next day, when Roland was about to go to the backyard of the calcination room to test the effect of the generator, the guards brought him great news that made him extremely happy. The chief alchemist from the Alchemy Workshop in Chishui City had arrived in Border Town and accompanied him. There is more than one person.

*******************

Kymer Struer walked very resolutely. That afternoon, he took his family and more than a dozen disciples on a merchant ship bound for Border Town. Unfortunately, Chames declined his invitation after much hesitation.

He did not disclose the contents of this letter to other alchemists. The more people who knew, the later the departure time would be. Kaimo was worried that the news of the successful firing of the crystal glass would soon reach the ears of the Duke, and it would be difficult for him to leave at that time. For such a lucrative luxury product, the Duke must want to firmly grasp it in his own hands.

He has already written the glass formula and firing method on parchment and stored it in the formula cabinet in the refining room, which can be regarded as a return for the Duke investing a lot of money in the construction of the alchemy workshop. It's just that in front of the truth of alchemy, neither crystal glass nor alchemy workshops are worth mentioning.

Five days later, Kymer finally met the Lord of Border Town who wrote the letter, Roland Wimbledon.

In the reception room of the castle, he had just finished his salute, and before he could sit still, he couldn't wait to say: "Your Highness, I want to have a good talk with your alchemist."

"My alchemist?" The other party smiled, "Before you came, there was no alchemist in Border Town. But now, you are my alchemist."

"You mean...you wrote those alchemy formulas yourself?" Kaimo directly ignored the second half of his sentence, and his face became a little pale. He suddenly thought of another possibility. The other party was a prince, and all the knowledge he received came from the teaching of the court tutor. If he could know all this, wouldn't it be that the King Capital Alchemy Association had already grasped the essence of alchemy changes? And he still wants to be above them, it's ridiculous to say it.

"Not exactly," Roland said, "These formulas come from ancient books more than 400 years ago, and I only discovered them by accident. It seems that hundreds of years ago, they called alchemy "chemistry." "

"Chemistry?" Kaimo felt a lot better when he heard that the formula did not come from the Royal Alchemy Association, but he was still surprised by the answer given by the prince. Alchemy books more than four hundred years ago? One must know that the Wangdu Alchemy Association has a history of less than two hundred years. Could it be that the future generations are not as good as the predecessors?

"Yes, in the book, those scholars mentioned a hypothesis, that is, the theory of immortality of matter. The matter that makes up everything in the world will not disappear or increase. They just change from one form to another. For example, this A piece of pastry." Roland pointed to the cake on the long table, "After you eat your stomach, part of it is absorbed by you, and part of it is excreted from your body. If you add the absorbed part and the part excreted from your body, their mass should be equal."

"Wait...Your Highness," Kaimo thought, "if I burn a piece of wood into powder, no matter how I weigh it, the weight of the powder will be lighter than the wood. If matter is indestructible, what is missing Where did that part of the material go?"

"These are also explained in the book," Roland laughed. "They turned into gas and water. And the water is baked and evaporated by the flame, so in the end you can only see the residue left behind."

"Gas?" Kaimo felt something in his heart ready to come out, "Does air have weight?"

"Of course, all matter has mass." The prince nodded, "It's also very simple to verify this. Put a pile of wood chips into the bottle, cover the bottle mouth and put it on the balance. After the balance, ignite the wood chips. Eventually you will find , the weight of the bottle will not change. Because the gas released by combustion cannot escape, it remains in the bottle.”

"This...was also written in an ancient book?" Kaimo asked eagerly, "Can you let me read that book?"

"If you can promise me a few conditions," Roland spread his hands.

"Please tell me."

"First of all, you have to work for me, and your salary will be calculated according to your remuneration at the alchemy workshop in Chishui City. Second, once you accept this job, you must abide by the confidentiality regulations. That is to say, you must not disclose the content of your work. To other alchemists. Third, if you agree, we will sign a contract. This contract is for a period of five years. After five years, you can freely choose to stay or stay. Correspondingly, if you accept these three conditions, Border Town will provide housing and a chemical laboratory. At the same time, I will also lend you the book "Elementary Chemistry" to read. You can come and ask me."

It doesn't sound like a harsh condition, Kaymer thought to himself, although words like confidentiality regulations and chemical laboratories are a mouthful, but he can still understand the general meaning. The five-year contract is not too long. He originally thought that the lord would ask him to stay in Border Town forever.

And...even if the conditions are harsher, he wants to witness that book with his own eyes, which records the essence of alchemy.

Thinking of this, Kaimo stood up and bent slightly: "I am willing to serve you, Your Highness."

"Very well, then it's settled." The prince didn't seem to care much about etiquette, "Your workplace is by the Chishui River. After signing the contract, I will take you to familiarize yourself with the laboratory. By the way, let me introduce you The purpose and operating regulations of those glassware."

What makes the chief alchemist feel a little bit wrong is why His Royal Highness is so proficient when it comes to alchemy, and even makes people feel confident? He is just an ordinary nobleman who came into contact with ancient alchemy books by chance? But these are trivial details, he suppressed his doubts, and asked, "I don't know what His Highness needs me to refine?"

"A high concentration of acid, the more the better," replied the prince. (To be continued. If you like this work, you are welcome to come to Qidian to vote, your support is my biggest motivation. Mobile phone users, please go to read.)
