What Lin Bei, Lord Dragon God, wants, Wanghai City will do as a top priority, but before that, what Lin Bei needs to solve is the problem of light bulbs.

The generator invented by Huang Yueying let Lin Bei know that bulbs that don't need a vacuum can also emit light, and they don't need tungsten wire, but the wire is definitely not good, the resistance of the wire is not large, and the heat resistance and wear resistance are extremely poor.

So what can be used instead of iron wire to become a luminous body?

Later generations were an era of knowledge explosion, although Lin Bei did not pay attention to the production of electric lights, but sometimes he could vaguely remember something, he remembered that there was a kind of incandescent lamp, which was as bright as daylight, and the brightness was amazing.

"What is it used as a wick in it? This kind of wick must be cheap, and it is easier to find, it should not be a metal, except for tungsten, other metals have small resistance, so it will only be other materials, so what materials are resistant, will glow? ”

"Loyalty? What shines? Lin Bei asked casually.

"Candlesticks, charcoals, coal, methane, flint, these will shine." An Zhongzhi also came casually.

Sometimes it's really a flash of inspiration, and when he heard the charcoal fire, Lin Bei's aura suddenly came, "Charcoal charcoal charcoal stick, uh, it seems to be really this kind of thing, right?" Charcoal rod, charcoal rod, rub, I'm so smart, loyal, call the blind Li quickly. ”

The blind man Li is in the craftsman's workshop, and he will arrive soon.

Lin Bei asked directly: "Master Li, charcoal was used to melt molten iron in the past, so can you make charcoal into a charcoal rod?" ”

"Charcoal rods? Adult, do you mean charcoal? ”

Lin Bei really wanted to slap his face. Yes, there is also charcoal, which has been improved several times and turned into ink, and charcoal is the main raw material, "So you can make this?" ”

"Wood will definitely do. The villain is not very proficient, but if the adult needs it, the villain can try it. "Blind Li doesn't dare to guarantee too much, the charcoal is still the best made by the carpenter, and the charcoal that Lord Ryujin wants definitely needs the best.

"Then Zhongzhi, call me the wood."

Lin Beixin said that fortunately, he was the Lord of the Dragon God, and he had everyone under him, which was also the advantage of those in power. If you change someone else, it is very difficult to gather these craftsmen, no wonder it will take a huge amount of money to do research in later generations, because they don't have anyone and nothing, so they have to buy it, but Lin Bei doesn't need it.

The wood soon came, Lin Bei asked him to make a charcoal pencil, and the wood asked, "My lord." The best charcoal? ”

"Well, the best. Are there any requirements for wood? ”

"Yes, my lord, the best charcoal needs to be made of sandalwood, and added to rosin, so that the words written are suitable for both shades and have a clear fragrance."

"Then use sandalwood."

"Okay, the little man went."

"How long does it take?"

"An hour at most."

"Speed it up a little more. Charcoal is made tightly and firmly. ”

"Adults can rest assured, villains can be saved."

Lin Bei was looking for a replacement material for the light bulb, and Huang Yueying was not idle, she asked the blacksmith to make a thin steel wire again, and the specifications all needed to be the same. Subsequently, Huang Yueying took matters into her own hands and carefully tied the steel wire on the iron cylinder, because Lin Bei said that there is a difference between the fineness of the iron ring and the size of the current that will be formed in the future.

Subsequently, Huang Yueying and Lin Bei went to the City Lord's Mansion and asked Lin Bei to tell her where she needed to install the generator.

"That's it, right? How is it? ”

"At the door? Adults, you need to build a table on top, and you need two for the placement of the bracket. ”

"Machine?"

"yes, do you want the sergeant to push the magnet all the time? Since there is no need for manpower, it must be replaced by machine. ”

"Oh, yes, then you can watch it, let the craftsman build the table."

"Okay."

Since Lin Bei didn't mind, Huang Yueying took full authority to deal with it and summoned the craftsman to start building the platform she needed.

Huang Yueying is quite resolute in doing things, and after the evening, Lin Bei came to the door again to take a look, good guy, there are already two Trojan horses on the two platforms above the door, these two Trojan horses stand opposite each other, the horse's head moves one after the other, and when the time comes, the magnet will be hung in the middle, and the two heads of the Trojan horse will hold the magnet one after the other, so that the magnet can always swing back and forth.

"Yueying, is this your flowing horse?"

"My lord, this Trojan horse is not comparable to a flowing horse, it's just some gadgets, the belly of the Trojan horse is bracketed, and the switchboard is also under the abdomen, and when the time comes, the Trojan horse will move for two days."

Subsequently, Huang Yueying first asked the Trojan horse to stop, and then asked the sergeant to hang the magnet and the iron ring up, Huang Yueying took out the charcoal rod made of wood, and the wood had been made at first, but the charcoal rod was too small, so then another one was made, this charcoal rod was about the thickness of an arm, and the two ends of the charcoal rod were tightly wound with a steel wire.

After a while, the charcoal rod suddenly lit up, then went out, and then lit up again, and as the amplitude of the magnet began to swing faster, the charcoal rod flashed and flashed, and it was already dark at this time, so it was very bright.

Lin Bei blinked, his heart hurt a little, he only remembered one thing now, that is, the electricity from this kind of generator is not continuous, it will be bright, but it is still countless short of the electric light that Lin Bei wants.

"My lord, it's lit up, it's too bright." Huang Yueying was so excited that she almost jumped up.

The people on the side also looked at the charcoal rod a little stupidly, and couldn't figure out why it was shining, but then, everyone felt very uncomfortable in their eyes and had to squint.

"My lord, is this an electric light? Too glaring, right? An Zhong squinted and said.

"This is also an electric light, but unfortunately it is not the kind of electric light that continues to shine all the time" Lin Bei was speechless, it seemed that he had to make a battery.

The first demonstration of the generator ended in failure, because almost everyone could not stand this flashing bright light, and their eyes hurt after a few glances, but although it failed. Huang Yueying is still very interested, she has already started to study batteries under the guidance of Lin Bei.

As for Lin Bei, although he really wants to use the electric light immediately, his current identity determines that he has a lot of things to deal with, so it is impossible to engage in the research and development of electricity all the time, and there is one thing in front of him that needs to be decided.

"Your Excellency. Guo Da asked to see him. ”

"Let him in."

Guo Da is the person in charge of the Chamber of Commerce, and now the commercial tax in Wanghai City is 35 percent, and this commercial tax is to throw away the cost, that is to say, it is 35 percent of the profits, if it is in modern times, this kind of commercial tax is very heavy, but in this era, this commercial tax is already quite low, and it is precisely because of this. The number of Wanghai people who wanted to do business increased, because it was obvious that Lord Ryujin did not disdain merchants, Shinong businessmen and merchants, and there was no rank in Wanghai City.

Guo Da entered the house, knelt down to Lin Bei first, and Lin Bei asked, "Guo Da, what's the matter this time?" ”

Guo Da didn't dare to get along with Lin Bei casually like An Zhongzhi. So he said directly: "My lord, now I want more and more people to do business in Haicheng. The previous time the steam engine was not allowed to be opened, now some merchants have asked me to ask if I can rent the Dawei Dragon King ship? ”

"Lease the Great Dragon King ship? Are those merchants ready to go by sea? ”

"Exactly."

"But you should know that if the Great Dragon King ship is removed from the steam engine, the speed will not be very fast, so the merchants also want to lease it?"

"Exactly. However, those merchants hoped that the adults would add sailing ships to the Great Dragon King to facilitate sailing on the sea. ”

"This is natural, so let's count the number of merchants who need to lease the Great Dragon King ship, and take hundreds of people as a ship. Report to Ansinon, and then I will ask the craftsman workshop to wait for you to prepare a few Great Dragon King ships, and let you go to sea by boat, but only two, if you have more, you will have to wait. ”

"My lord, can I buy it?" Guo Da then asked.

Lin Bei smiled, this Guo Da has to inch in, but he should help the merchant to ask, compared to leasing, the purchase is obviously more cost-effective, the businessman, you have to have this keen business sense.

"It's not impossible, but do you think that with the financial resources of the people of Wanghai now, who has the money to buy a Great Dragon King ship?"

The Dawei Dragon King Ship is the largest ship in Wanghai City, with a total length of eighteen lengths, which is higher than the big ship in the Central Plains, and it is definitely the largest ship in this era.

"Oh, that's it, besides, my lord, if I go by sea and trade with a foreign country by the sea, what should I do to sell the goods I bring back? Can an adult tell a villain? Merchants are quite concerned about this matter. ”

Lin Bei thought about it, but he was negligent in this aspect, so he immediately asked the sergeant to call An Zhong and tell him about it.

An Zhongzhi groaned and said, "My lord, it depends on what kind of goods it is." ”

Lin Bei said with a smile: "Since the merchant will bring it back from a foreign country, it must be something that I don't have in Wanghai City, the sea is far away, and there are many dangers, this lord thinks that he should accept it at a high price, so as not to chill the merchant." ”

Guo Da hurriedly said: "My lord is wise. ”

"Then it needs to be useful to me in Wanghai City, right?"

Lin Bei nodded: "Since the merchants have this concern, so let's be loyal, you will draft a regulation to refine this aspect, so that the merchants can have a target and everyone is enthusiastic." ”

"No."

The regulations on shipping were soon issued, which stipulated at what price Wanghai City would buy the things brought back by shipping, jewelry and jade are all valuable, and the price is the same as that of Wanghai City, in addition to jewelry and jade, foreign specialties, such as exotic food crops, cash crops, etc., are extremely high-priced, in addition, this regulation also added a very special kind of goods - slaves.
