The principle and structure of the DC generator are very simple, Roland as a child removed more than a dozen four-wheel drive motors, from ordinary whiteboard motors to the legendary gold super, but also their own hands around the rotor copper wire.These motors are typical DC motors.

There is no structural difference between the &&NB DC generators and DC motors, which are essentially the same thing and the functions are interchangeable.As long as other machines drive the motor rotor rotation, so that the wires continue to cut the magnetic induction wire, the energy source continuously generates induced current.

With the help of Enigma Moon and Anna, Roland spent only half a day to install a simple DC motor, the stator part is all made of wood, and then the mystery moon to give magnetism.The commutation of the end of the rotor is embedded in a cross-section of the log, and the center of the round wood has a hole, which can be connected to the steam engine shaft.Such a construction is convenient to make, but also to ensure that the commutation of the pieces are insulated from each other.

As for the new steam engine, it became he and the mystery moon watching Anna perform her skill-making skills.When it is necessary to make large parts, she will make the black fire open, like a cloth, a pile of iron ingots wrapped in it, after melting and then shrink the black fire, pressing into a plate to meet the size requirements, and finally cut and form.

The next day, as Roland was preparing to test the effects of the generator in the incubator’s backyard, the bodyguard brought some good news to him that the chief alchemist from the Redwater City Alchemist had arrived in the town of Border, and more than one person had come along.

& amp; nb************************************************************************************************************************************

&nb Kemo Squear walked very decisively, and that afternoon he took his family and more than a dozen disciples on a merchant ship to the border town.Unfortunately, Chames hesitated and repeatedly refused his invitation.

He did not disclose the contents of the letter to other alchemists, and the more people he knew, the later he would leave.Kemo was worried that the news of the successful firing of crystal glass would soon reach the Duke's ears, and that when he wanted to leave, it would not be so easy for this highly profitable luxury product, and the Duke must have wanted to firmly grasp it in his own hands.

&nb has written glass formulations and firing methods on parchment, stored in the formula cabinets of the refining room, and is a return to the Duke's investment of a large amount of money to build the alchemy workshop.But in the face of the truth of alchemy, whether it is crystal glass or the alchemy workshop, it is not worth mentioning.

Five days later, Kemo finally met Roland Wimbledon, the lord of the town of Borders, who had written the letter.

In the living room of the castle, he has just finished his service, and his ass has not yet sat firmly, he can't wait to say: "Your Highness, I want to talk to your alchemist."

& mp; nb "My alchemist?"The other person smiled, "Before you came, there was no alchemist in the border town."But now you are my alchemist."

& nnb “You mean ... those alchemy formulas you wrote yourself?”Kemo ignored the second half of his sentence directly, and his face became a little pale.He suddenly thought of another possibility, the other party is the prince, the knowledge received all comes from the teaching of the court teacher, if he can know these, will not the royal alchemy association has long mastered the essence of the change of alchemy?And they want to be above them, and it’s ridiculous to say it.

“Not exactly,” Roland said, “these formulas come from ancient books from more than four hundred years ago, and I discovered them by chance.”It seems that hundreds of years ago, they called alchemy a chemical.”

& mp;nb "learning"?Kemo heard that the formula did not come from the Royal Alchemy Association, and his heart was very good, but the answer given by the prince still surprised him.Books from over 400 years ago?You know, the Wangdu Alchemy Association is less than 200 years old, are future generations inferior to the predecessors?

"Yes, in the book, the scholars mention the hypothesis that material immortality is.The matter that makes up everything in the world does not disappear or increase, they just change from one form to another, such as this pastry, Roland refers to the cake on the long table, "after you eat the stomach, there is a part of you absorption, part of the body is excreted, if the absorbed part and the part excreted out of the body together, their mass should be equal."

"Wait ... your Highness," thought Camus, "if I burn a piece of wood into powder, no matter how we weigh it, the weight of the powder is lighter than wood."If matter is immortal, where is the missing part of it?”

“These are also explained in the book,” Roland laughs, “and they become gas and water.”And the water is baked in flames and evaporates, so in the end you can only see the residue that remains.”

& mb "gas"?Kemo felt that there was something in his heart to call out, “Does the air have weight?”

& mb “Of course, all substances have quality.”The prince nodded, "It is very simple to verify this, put a pile of wood chips into the bottle, cover the mouth of the bottle on the balance, and wait until the balance will light the wood chips."Eventually, you will find that the weight of the bottle does not change.Because the combustion of the gas cannot run out, it remains in the bottle.”

& mp;nb “Is this... written in ancient books?”Kemo asked eagerly, “Can I see that book?”

"If you can promise me a few terms," Roland said.

& mp;nb "Please say."

"First of all, you have to work for me, and the salary is calculated according to the remuneration you paid when you were in the Red Water City alchemy workshop.Second, once you accept the job, you must comply with confidentiality rules.In other words, the content of the work should not be disclosed to other alchemists.Third, if you agree, we will sign the contract.After five years, the contract will be free to stay, and the results of the alchemy will no longer be subject to confidentiality regulations and can be presented to other alchemists or alchemists.Correspondingly, if you accept these three conditions, the border town will provide housing and chemical laboratories.At the same time, I will also lend you the book "primary chemistry" to read, if you do not understand, you can ask me."

& NB doesn't sound like harsh conditions, and Kemo thought that although words such as secrecy regulations and chemical laboratories are really mouthful, they can still understand the meaning.The five-year contract was not too long, and he had expected the Lord to make a request to stay in the border town forever.

And ... even in harsher conditions, he wanted to see firsthand the book that chronicled the nature of alchemy.

When &nnb came to think of it, Kemo got up and bent down a little: “I would like to serve you, Your Royal Highness.”

"Very well, that's it," the prince didn't seem to care much about etiquette, "and your place of work is on the banks of the Redwater River, and after signing the contract, I'll take you to the laboratory and, by the way, introduce the use and operating regulations of the glassware."

& NB makes the chief alchemist feel that something is wrong with why His Royal Highness the Prince has talked about the alchemy so skilled that it even makes people feel good about it?Is he just an ordinary nobleman who accidentally came into contact with the ancient alchemy?But these are all minutiae, he pressed down to doubt, asked, "I don't know what your Highness needs me to refine?"

& mb “High concentrations of acid, the more the better.”The prince replied.(Not completed.If you like this work, you are welcome to start the project, and your support is my biggest motivation.Mobile phone users please read.)
