Of course, Li An will not object to Li Longji's request to put a set of power generation test devices that he has just invented in Daming Palace, after all, the emperor and the concubine are very fond of it, and the craftsmen are already very proficient in the whole set of technology, and they do not need to refer to the test device at any time, and they can be mass-produced immediately.

"Since Your Majesty and the concubine like it so much, then this test device will be temporarily placed in Daming Palace, but the room in the courtyard next door needs to be better isolated, and the noise of the power generation device is still louder, just like a train."

Ang Lee immediately agreed, and in order to prevent noise from disturbing the tranquility of the palace, he proposed to improve the power generation room to make it more difficult for noise to escape.

Li Longji was very happy, and handed over all the things to Li An to do, so that in the future, Li An could enter and leave the palace freely without anyone's permission.

In fact, when Li An didn't mention the noise next door just now, Li Longji and Yang Yuhuan were attracted by the beautiful scenery in front of them, and they didn't realize that there was noise around.

"San Lang, there is still some distance from the dormitory, wouldn't it be better if these electric lights were moved to the dormitory, by the way, there is also a back garden, the back garden is much bigger than here, if it is arranged like this, it must be even more beautiful."

Yang Yuhuan admired the beautiful lanterns around him with an intoxicated face, and put forward his own suggestion, which can also be said to be going.

Li Longji looked at Li An as if asking for help, and motioned for Li An to answer.

Li An understood and said: "The concubine Niangniang doesn't have to be anxious, the electric light system has just been invented, and it has not yet entered the mass production stage, and it is not yet able to meet your requirements, however, if you want to move the electric light here to the dormitory, it is not difficult, you only need to use a copper wire to lead to the dormitory, and then you can arrange the electric light, however, it is late today, and the arrangement will start early tomorrow morning, and it will definitely be able to let Your Majesty and the concubine see the dormitory as bright and beautiful as here before tomorrow night." ”

When Li Longji heard this, he hurriedly responded: "Li Shilang is right, it's getting late in a few days, let's start arranging it early tomorrow morning!" Besides, my dormitory still needs to be prepared, Aman, we'll be staying somewhere else tonight. ”

After all, the emperor's bedroom is a very private place, not everyone can enter casually, if you want to arrange the lighting system, you must go in and out of the emperor's bedroom, so many craftsmen in and out, in case you touch the emperor's bedding, or damage the valuables in the room, the consequences are not generally serious.

Therefore, Li Longji must prepare for a long time in advance, move all the important daily necessities of the dormitory, and move them back after the lighting system is installed.

Of course, Yang Yuhuan has no opinions, she is generally more reasonable, of course, it is only relative, she also has times when she is rude and willful, for this reason, in history, she was driven home twice by Li Longji.

"Li Shilang, this palace lamp is much brighter than before, is it also an electric light inside?"

Yang Yuhuan looked at the palace lamp curiously and asked.

"What the concubine said is that all the candles in the palace lamp have been replaced with electric lights, which is brighter and more beautiful."

Li An hurriedly explained, and asked people to take away the lampshade of the palace lamp, so that Yang Yuhuan and Li Longji could see it clearly.

"Wow! This is the light bulb, and it turns out that the light bulb inside looks like this. ”

Yang Yuhuan and Li Longji were amazed, looking at this inconspicuous little thing that could shine.

"Li Shilang, can you take this thing down and take a look?"

Yang Yuhuan said.

"Don't, concubine Niangniang, this electric light is very hot when it is lit, and it will burn your hands, and the medicine jade is very thin, and when you encounter a cold palm, it may explode and hurt your hands, so you must wait for the bulb to be turned off for a period of time before you can take it down."

Li An hurriedly stopped and explained.

"Oh, you need to turn it off first, so how do you turn it off? The candles are blown out directly, and this electric light should not be blown out, it has no fire. ”

Yang Yuhuan looked at the light bulb in front of him and asked curiously.

"Well, the lights have special switches, as long as you press them lightly, you can switch them on and off at will, because of time constraints, there is no separate switch for each bulb, this row of five lanterns, only one switch is installed, right here."

Li An walked to the switch and pressed it gently, and suddenly, all the five palace lights were extinguished, and the surroundings were a lot darker.

"Guifei Niangniang, this is the switch, you can turn it on and off at will with just one press, you try it yourself."

Li An guided softly, and asked Yang Yuhuan to try to use the switch.

"That's how you can just press it?"

Yang Yuhuan opened his mouth to confirm it, and after getting an affirmative answer from Li An, he reached out and gently pressed the switch.

"It's lit, it's really all lit."

At the moment when Yang Yuhuan pressed the switch, all five palace lamps were lit up, and the surrounding area returned to bright colors this time.

"It's so easy to control the lights, come, let me try it too."

Li Longji thought it was interesting, walked over gently, and pressed it many times, so that the palace lights would be on for a while and off for a while, and provoked Yang Yuhuan to follow suit, pressing back and forth.

"Your Majesty, Concubine Niangniang, such frequent switching back and forth will cause great loss to the light bulb and will reduce the service life of the light bulb."

Li An opened his mouth to remind.

Li Longji was stunned for a moment, nodded and said: "Li Shilang reminds that everything has a lifespan, and of course this light bulb will also have a lifespan, I don't know how long this light bulb can last?" ”

Li An touched his head, shook his head and said: "Your Majesty, the light bulb has just been invented, as for how long it can be used, Weichen has no bottom in his heart, however, the life of the bulb is definitely much higher than that of a candle, and it will not be bad if it is used for a month, Weichen can guarantee it, in addition, the service life of each light bulb is different, even if it is used at the same time, it is impossible to damage it at the same time, so it is okay to replace one if it is broken." ”

"A month, you can use it for so long, it's really a good thing!"

Li Longji was very satisfied, and asked a lot of common sense about electric lights, as well as precautions for use, Yang Yuhuan asked that all light bulbs installed in the dormitory should have separate switches, so that it is most convenient, and Li An agreed one by one, saying that he would meet her requirements.

In addition, when Yang Yuhuan went to enjoy the garden lights, Li An talked with Li Longji about the first batch of power generation devices manufactured to meet the needs of the east and west markets or the palace first, and Li Longji replied without hesitation that it was necessary to meet the needs of the palace first, and then to meet the needs of the capital, and then gradually spread to other industries.

Li Longji does not have the slightest disgust for Li Longji to take care of his own enjoyment and occupy the best and best resources, after all, he himself is like this, everyone is the same kind of people, just understand each other.

Because a medium-sized power generation device can meet the needs of thousands of light bulbs, and in the courtyard in front of you, there are only a few hundred light bulbs that are on, and there is still a large balance of power, so even if a large number of electric lights are arranged in Li Longji's dormitory, it can fully meet the demand for full power, and there is no need to remove the light bulbs in the courtyard in front of you.

In the process of invention, Ang Lee has manufactured a lot of related equipment and a lot of materials, and after the first bulb was lit, it took an hour to produce hundreds of bulbs and arrange them in the Daming Palace, so when the second day began to be arranged, Ang Lee would let the craftsmen produce a sufficient number of bulbs, which could definitely meet the needs of the palace.

In addition, because there is still a lot of power left, Li An suggested that Li Longji install electric bulbs in a large area of the courtyard where the generator set is located in front of the dormitory, so that the entire area will be lit up.

In addition, the entire Daming Palace only needs three generator sets, which is enough to make the entire palace bright, and it is many times brighter than before.

In addition, the Taiji Palace, including the Imperial City, is relatively large, and in order to maintain sufficient night lighting needs, five generator sets are needed, and as for Xingqing Palace, only two are enough.

In this way, the three palaces in the capital need ten generator sets, and the roads and streets in the city, as well as hotels, and even the homes of the people, the demand for generator sets is even greater, however, this generator set, it is not difficult to manufacture, after mass production, it can quickly meet the needs of the capital, and can quickly manufacture more generator sets, to provide various important facilities outside the city, as well as trains and steam ships.

Of course, all this takes time, and it takes production step by step to gradually meet the needs of Datang, Li Longji has promised Li An that as long as Chang'an City is an area with electric lights, the night ban will be lifted, and as long as all places in the capital are connected to electric lights, the night ban will be completely lifted in the whole city, and even all the walls will be demolished step by step, so that Datang's transportation will become more convenient and business will be more prosperous.

The entire power generation system has a cost, manufacturing, use, and maintenance all cost money, for the use of the palace and roads, it is naturally the financial burden of the imperial court, and for the merchants in the east and west markets, as well as the use of electric lights in the homes of the people in the future, they must pay out of their own pockets.

How much is the most suitable for the user, of course, it is necessary to use the electricity meter to calculate, and the project that Ang Lee is tackling is the electricity meter, which can clearly show how much electricity is used, so that it is very convenient to collect the usage fees of the people.

After talking to Li Longji for a long time, Li An took the craftsmen and surveyed the neighborhood to find out the best wiring scheme.

For Ang Lee, the best wiring solution is to let people not see the wires, which is the best and best wiring method, and if it is not easy for people to see, either buried in the ground, or along the corner of the inconspicuous place of the wire, so as not to destroy the overall environment, will not make people feel eyesore.

In addition, the color of the wires should also be coordinated with the environment as much as possible, when passing through the wall, the color of the wires should be the same color or close to the wall, and when entering the corridor wood, it is required to be consistent with the color of the wood, so that it is not easy to be found.

After determining a few routes, Li Ang discussed with the eunuchs in the palace, asking them to see if these areas could be dug and whether they would violate a certain taboo in the palace, and Li An asked if there were any points to pay attention to in these routes he proposed, such as a certain place that could not be moved, a certain piece of land could not be dug indiscriminately, and so on.

The eunuchs in the palace were also very cooperative with Li An, and answered Li An's questions one by one, and also said that they would give detailed guidance to the craftsmen when they were carrying out construction, and there would be no accidents.

After determining the route, Ang Lee assigned the task to a number of craftsmen, so that they were responsible for the general wiring work, as for the detailed wiring work, after entering the palace on the second day, Ang Lee would personally guide the craftsmen to make specific arrangements.

When Li An left the Daming Palace, the craftsmen were still making preparations, and they had to discuss how to distribute the specific work, what tools to prepare, when to enter the palace to start working, and which eunuch to ask for help in the situation.

That night, Li Longji and Yang Yuhuan thought about it for a long time, and then stayed in the courtyard full of lights, because this place is the brightest, not only the outside is bright, but the inside of the room is also bright, and people will feel very comfortable living in such a room.

Early in the morning of the second day, the craftsmen began to enter the palace one after another, to confirm the work assigned last night, and then began to work officially, because the palace is not an ordinary place, all the craftsmen who work are all in order, no one dares to make a loud noise, and there are many eunuchs watching next to them, so as to prevent these craftsmen from running around and breaking the rules of the palace.

After the main line was almost arranged, Li An arrived at Daming Palace, and in accordance with the aesthetic theory, combined with the actual situation of each palace, designed different layout styles, and asked the craftsmen to do it in strict accordance with their requirements.

After entering Li Longji's dormitory, Li An found that it was basically empty, the bedding and daily necessities had been moved, and only the large furniture was left in place because it was difficult to move.

More than a dozen craftsmen stood inside and worked, and several little eunuchs stood by to watch to prevent these craftsmen from damaging the emperor's things.

The emperor's bedroom must be the best arrangement, the more light bulbs of all kinds the better, not necessarily fully open, but each color of the bulb, or a certain array of light bulbs, can form a completely different lighting atmosphere, will make the people who live in it, have a completely different real feeling.
