"You're welcome, just sit down. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

As soon as he entered the door, in the living room, the old man casually pointed to the chairs that were placed.

"Thank you. "You're welcome. He nodded, "So, what's the problem?"

"A question that has been bothering me for a long time. ”

In his hand, a book opened, and Albert pointed to a diagram, a complete structural diagram, and asked the question that had been bothering him for a long time: "I wonder why, when I reach the sixteenth node of this third area of magic, it produces a shock, such a phenomenon has the potential to destroy its overall integrity, is there any solution?"

"Is this the case, I've had such a problem before. The old man named Oshas pondered, and gave his answer, "This is normal, you should connect the fifth and nineteenth points directly, so that you can directly omit this link." ”

"Thank you, this problem has been bothering me for a long time, and now it has finally been solved. "Sometimes, there are mistakes in books that you can't fully trust. ”

Speaking of which. Cecilia looked around, "It's very well furnished." ”

"Haha, that's nothing. Oshas stroked his beard and laughed, "It's just that there's nothing to do, it's free." ”

"I've heard you're an inventor. "I did build something. He pointed to a locked door, "That's my studio, do you want to see it?" "Is that okay?" "Of course, it's all useless." ”

Following the old man, they walked into the room, which was unenchanted and ordinary.

Inside the door is where the old man works.

Bright and tidy, that's the first impression here.

The floor was spotless, the light was discerning, all the items were neatly displayed on the shelves according to their efficacy, function, size, all the books, sorted, look up at the ceiling, and you could see a lamp, a magic lamp, which completely illuminated the place, his work desk was in the center, and the tools were ready, ready to start his work.

"What a nice place. They were amazed.

This is the first time the two have seen a wizarding studio owned by themselves, and everything is full of novelty.

"Thanks, you can take a look, the shelves over there are all small things I made myself. ”

"What is this?" she said, holding a crystal ball in her hand. "The [self-detector] I built myself, it will be uncomfortable to use on the market, and the data obtained with it is just as accurate, but the discomfort is much less, but the cost of making it is a bit large. ”

"What about this?" "The enchanted product of the [Self-Blessing Technique] can make people think faster when worn on the body. ”

"What about this?" "With the [Magic Energy Shield], it consumes much less mana when defending. ”

There are many things here, with different effects, and they are used for fighting, and they are necessary for life.

Finally, Albert saw something that looked familiar to him.

"What is this?" His hand shook violently.

Electric lamps are artificial lighting appliances that use electricity as an energy source, and electric lights convert electrical energy into light energy to illuminate humans at night or in a dark room. Since the invention of the electric light, it has given a great impetus to the development of mankind.

Before the advent of electric light, the common lighting tool used by people was kerosene lamps or gas lamps. Because it burns kerosene or gas, it has a strong black smoke and a pungent odor, and it is very inconvenient to add fuel and scrub the lampshade frequently. What's more, this kind of lamp can easily cause fires and cause serious disasters. For many years, many scientists have tried their best to invent a safe and convenient electric light.

At the beginning of the 19th century, a British chemist used 2,000 batteries and two charcoal rods to make the world's first arc lamp. But this light is too strong to be installed on streets or squares, and cannot be used by ordinary households.

Finally, on October 21, 1879, an American inventor finally lit the world's first practical electric light through a long period of trial and error. Since then, the name of this inventor, like the electric light he invented, has entered thousands of households. He is Edison, who was praised as the "King of Invention" by later generations.

That's what the book says, and Albert doesn't remember a word.

All he knew was that the person who invented it was Edison.

The old man didn't notice the excitement that rose up for a moment, and suppressed for a moment, and said to himself.

"The inspiration for making it came from lightning, and electricity can emit light, so I wanted to use a carrier that could replace the magic lamp. ”

"I don't think it's very useful, people don't need too much light source, and it doesn't matter much if there is light at night, so its only purpose is to illuminate my laboratory, but many people want to decorate their rooms with lights after hearing about it. ”

"Other than that, it's not very useful. ”

"In order to make it, I experimented with a total of 1,382 materials before I found the best carrier. ”

"Because it didn't work, I kept it in that corner. ”

"I've been wondering if electricity can replace magic energy and become an energy source that can be used by the public, and this light bulb is just a test in the process, and the process of generating electricity is much simpler than magic energy, and the consumption of production is very small. ”

"It would be nice if one day, electricity really replaced magic energy. ”

"That means that everyone will be able to use magic items as they like the rich, and it will be massively popular. ”

"It's a pity that all the current attempts have failed, what a fool I'm ... ”

"Sorry, I'm talking nonsense again. Oshas shook his head and sighed slightly, "I made all of these things, but none of them have much effect, anyway, thank you for visiting." ”

"You are such a great inventor. Albert gently put down the light in his hand, "Very great, inventor." ”

"Is it great... The old man laughed, "I can't say it, but I like the title of [inventor] very much, thank you, my wish since childhood is to make something useful so that future generations will know my name." ”

"So I've been trying to get results one day. ”

"It's going to come to fruition, it's going to happen. He nodded affirmatively, "You will definitely achieve great results." ”

"Haha, then, take your good word, little one. ”
