Lawson and Vincent signed a formal wand contract, and he returned to the Prancing Horse Mansion.

Along the way, his mind was full of thoughts, and the ideas that had popped up before were like catalysts, giving rise to a whole bunch of new ideas.

"What is a wand?" He asked himself.

For the ordinary people of this world, it is the magician's spell-casting weapon.

But if you think carefully and use scientific thinking to explain, then the essence of the wand should be a tool for energy conversion.

The key lies in the words 'energy conversion'.

"Energy Conversion...... The most common form of the Thunder Wand, the Flashing Technique, converts energy into electricity. The Fire Wand, the Breath of Fire or Fireball, is the conversion of energy into heat and light...... Whether it's a lightning wand or a fire wand, the attack magic it unleashes contains a huge amount of energy. ”

"Energy can't come out of nowhere, it's either provided by a magician or stored in a wand in the morning."

"A normal Thunderbolt Wand, which needs to be charged to use. Obviously, the energy when attacking is provided by the wand, and the mage is only responsible for activating and controlling the release of energy. In this way, using a wand can greatly reduce the burden on the mage and speed up the casting of spells. ”

Thinking of this, Rosen already knew the basic structure of the wand.

"To achieve this function, a standard magic wand must contain three parts, namely an energy storage, a controller, and an energy converter."

"I'm going to build a wand that ordinary people can use...... Neither the energy reservoir nor the energy converter need to be altered. The only change is the controller. What I want to do is lower the barrier to entry for the controller. ”

Rosen's thinking became clearer and clearer: "Hehe~ The magic wand that ordinary people can use, there is no price, let me make a price, now I am going to make a lot of money." ”

The carriage 'gurgling' drove to the Prancing Horse Mansion, and Lawson stayed in the carriage, quill in hand, and began to sketch his wand on parchment.

When the carriage arrived at its destination and stopped at the entrance of the mansion, Lawson opened the carriage and jumped down with a smile on his face.

The butler greeted him and saluted, "Sir." ”

The housekeeper's name is Ah Fu, he is over 50 years old, has no children and no daughters, and has been a housekeeper all his life, including 20 years of serving the Prancing Horse Mansion. Rosen saw that he was loyal and honest, and that he was getting older, so he continued to use it.

Rosen nodded back and asked, "Where's Lady Veronica?" ”

"In the studio on the second floor, I'm painting." Ah Fu replied.

"What about Miss Anne?"

"Training in the underground kennel field."

"Understood."

Rosen rolled the parchment in his hand in a circle, strode towards the studio on the second floor, and when he arrived at the door of the studio, he knocked lightly: "Veronica, are you free?" ”

"Come in." An answer came from the room.

Rosen pushed the door open and saw Veronica sitting in the corner of the house with a large drawing board in front of her. She holds a paint tray in one hand and a variety of brushes in the other, and paints various colors on the drawing board.

She is very skillful, and on the drawing board, the outline of the Prancing Horse Mansion is already faintly visible.

Rosen stood against the wall with his arms folded on his chest, and said with a smile: "I didn't expect you to have good painting skills." ”

"It's not good. I haven't done it for many years, and the technique is already very jerky. After speaking, she put the wooden paint tray on the table next to her, picked up a rag and wiped the paint on her hands: "Look at your appearance, do you have something to do with me?" ”

Rosen nodded: "I talked to the merchant, and we made a contract. From now on, I was in charge of making alchemical utensils, and he helped me sell them. In the end, the profit obtained is divided into 28 percent, and I am 8 and 2. ”

Veronica nodded, "You look very happy, but it's not enough to make you so gaffe, so, you still have something to say?" ”

Rosen smiled: "I can't hide anything from your eyes." There is one more thing, indeed. Vincent, uh, that's what the merchant told me that wands are very profitable, and a normal lightning wand can sell for 200 gold dragon coins. ”

"So what? The craft of making this offensive wand has always been monopolized by the Nilogaard Academy, and it has never been passed on. Could it be that you're still going to build a wand? Veronica pouted, disapproving.

Rosen shook his head repeatedly: "No, no, no, at the moment, I naturally won't make a thunderbolt wand." However, in my opinion, this is not difficult, with a little research, it is not difficult to create an ordinary thunderbolt wand. ”

When Veronica heard this, her expression suddenly froze, and she said, "Well, I believe you have this ability." However, this thing is a monopoly of Nilogaard Academy, if you sell the Thunder Wand in other cities, forget it, if you are in Nilogaard City, I'm afraid you will get into big trouble. ”

Rosen was slightly shocked in his heart: "Oh~ I really didn't expect this, thank you for reminding me." ”

But then he laughed again: "Of course I won't sell the Thunderbolt Wand. In fact, I'm going to build a wand that can be used by ordinary people. ”

Veronica was finally surprised: "A wand that can be used by ordinary people, are you sure you can do it?" If you can do it, you can sell it for a high price! ”

"Hahaha, in fact, I've already designed it, and now it's just missing the materials." Lawson waved the scroll in his hand.

Veronica understood: "You want me to find you materials again?" ”

"Don't you want to see my wand?" Lawson shook the scroll in his hand.

As a result, as soon as he finished speaking, he felt a fragrant wind blowing in front of him, and then, the scroll in his hand was gone, and when he looked up, Veronica was still standing in place, but there was an extra scroll in his hand.

She opened the scroll, looked at it closely, and whispered as she looked, "Glitter Wand." Two dry batteries, one incandescent electric bead, one push-button switch, and one wooden cylinder...... What are dry batteries and incandescent beads? I've never heard of it. ”

Rosen spread his hands: "That's the code I wrote." You just need to look at the list of materials at the bottom. ”

Anne jumped directly to the bottom and saw that it read: "wolframite, graphite, brass, limestone, quartz, ......"

Looking at it all the way, she frowned and said: "Except for wolframite ore, it is a commonly used material, and there are many of them in Nilogaard City, you can send a servant to find them for you." ”

Rosen smiled: "I just want you to help me find wolframite." I'll find the rest myself. ”

"Wolframite ..... It's hard to find...... Okay, I'll help you find it. In the city of Nilogaard, I happened to know a few special ore merchants. ”

"Thank you very much, thank you very much." Lawson bowed repeatedly.

He wanted wolframite ore because he wanted to extract tungsten metal, because tungsten has the highest melting point of all metals, more than 3000 degrees, and the evaporation rate is extremely slow, which is the best filament material for incandescent lamps.

Of course, it is not necessary to use tungsten filament, he can also use things like carbide bamboo fiber instead of tungsten filament, or simply make light-emitting diodes instead of incandescent beads.

However, the lifespan of the former is not ideal. In the case of the latter, the light-emitting diode is a good thing, several levels more advanced than an incandescent lamp, and he doesn't want to take out such a good thing so quickly.

"Alright, alright, I'll go find it for you. Don't be idle, the rest of the materials are easy to find, but there are so many kinds of materials that it will take a lot of time. ”

"Hehe, don't worry, it won't take much time."

After the negotiation, Rosen and Veronica began to go their separate ways.

While the two of them were looking around the city for materials to make a glitter wand, a large passenger ship with ornate exterior docked quietly at the docks of Nilogaard City.

After a while, a woman in her fifties stepped out of the boat. Along the way, she was carefully guarded by a dozen guards with shields, and eventually boarded a lavishly decorated carriage.

In the carriage, the magician Fleming. Ben was already waiting, and when he saw the old woman, he bowed slightly and said, "Master Niya, something strange has happened in the academy these days when you are away. ”
