Li Longji is still relatively cautious in urban reform, and he did not implement all the suggestions put forward by Li An at once, but carried out reform step by step, little by little, starting with opening up the east and west markets, and then gradually extending to more places.

Each extension is a huge social progress, and Li Longji will only carry out the next step of reform on the premise of affirming the achievements of the previous stage, so as to prevent the step from being too big and causing unpredictable risks.

After the walls of the East and West Cities were completely demolished, Li Longji observed for nearly a month, listened to reports from all aspects of the officials in the capital, and sent his henchmen to inspect the East and West Cities at night and the roads where the night ban was lifted.

This time, the action is still not very big, that is, the east and west sides of the east and west markets, such as Pingkang, Wuben and other 16 square walls are all demolished, and the night ban in this area is lifted, so that the east and west cities will be connected, and the development of commerce will become more prosperous.

Of course, the larger the area where the night ban is lifted, the higher the requirements for all aspects of the imperial court, at least, it is necessary to equip more night patrol personnel to ensure the order of night commercial activities, and the requirements for the lighting system are also relatively high, the larger the area of the open night curfew, the more lighting braziers are needed, and the nearby walls need to be painted white, which is also a big project.

Whether it is to increase the number of night patrol personnel, or to prepare braziers and paint the walls, it will cost money, which will increase the financial burden of the imperial court on the surface, but fortunately, the Tang Dynasty is not short of money now, especially the continuous prosperity of commerce, so that the tax revenue of the Tang Dynasty has become more and more abundant, that is to say, after the implementation of the night ban policy in the Tang Dynasty, it has actually not increased the financial burden, but increased the financial revenue, which makes Li Longji quite satisfied.

On the night of winter, Li Longji invited Li An and the ministers to go to the gate tower of the Vermilion Bird Gate of the imperial city, ready to enjoy the beautiful night view of Chang'an City together.

Of course, it was necessary to go back at night to enjoy the night view, but many ministers still arrived at Suzaku Gate early before it was dark to show their good attitude.

Li An did not go early, after he was busy with his work, he returned to the courtyard to reunite with his wife, and then after the sun had set, he got into his special carriage and hurried to the Suzaku Gate accompanied by the guards.

Although Li An has a token and can directly break into the night ban, Li An still chooses to enter the city from Jinguangmen in the west, and by the way to see what the road situation is like and whether there is still congestion, so as to urge Li Longji to further expand the intensity of reform.

When he arrived at Jinguangmen, Li An saw a scene that made him very happy, the road was very smooth, and there was not the slightest congestion and chaos, because the east and west markets were open for twelve consecutive hours, merchants and people naturally did not need to worry, and it was expected that the roads would no longer be congested.

After dark, the braziers on the roads and streets began to light one by one, and the streets instantly lit up a lot.

"Hey, why didn't Li Shilang come, didn't anyone inform him?"

Li Longji glanced at the ministers casually, but did not see Li An's figure.

"Everyone, the slave and maid sent someone to inform Li Shilang early in the morning, maybe something happened on the way to delay it."

A little eunuch explained.

Li Longji nodded, looked at the night scene in front of him, and felt a lot of emotion in his heart, this lively scene was all from the hands of Li An, if it weren't for Li An's enlightenment creation, step by step to promote the prosperity of commerce, and proposed to lift the night ban, the capital would not have such a beautiful scenery, and at this critical moment of appreciation, Li An did not appear, this is not the biggest regret.

"Everyone, Li Shilang has arrived, and the slave and maid recognize his carriage."

The little eunuch looked sideways at Li An's carriage and spoke.

"Huh! Li Shilang actually didn't ride a horse, but chose to take a car, this is not his style! ”

One of the ministers quipped.

"It's good to come, now we can enjoy the night view with confidence, hehe!"

Li Linfu opened his mouth and laughed.

"Your Majesty forgives your sins, Weichen is late."

Li An had just arrived at the Suzaku Gate, but found that Li Longji was already standing here, and felt that something was wrong, so he hurriedly opened his mouth to plead guilty.

"It's not too late, it's not too late, it's not a moment in time? It's early for me, haha! ”

Li Longji was in a very good mood, and he didn't look angry at all, and caused all the ministers to laugh together.

Li An looked around casually, and found no trace of An Lushan, that is, the emperor did not invite him, which means that An Lushan has completely fallen out of favor, and there will not be much future in the future.

It is a great honor to enjoy the night view of the capital with the emperor, and at the same time, it can also prove that this person is valued by the emperor, after all, the emperor will not stand with the person he hates to enjoy the beautiful scenery.

After placing braziers at intervals and painting the walls on both sides of the road white, the whole street becomes very bright at night, at least, the visibility is about a mile, and you can see people and things in the distance very clearly, thus giving people a sense of security.

Of course, this brightness is much worse than the urban lighting of later generations, and it is not an order of magnitude at all, and this is also because there are still too few materials in this era, and the technology is still relatively backward and cannot be better.

"The street is still not bright enough, and we still need to continue to increase the number of braziers, especially on the road in front of us."

Li Longji admired it for a long time and gave a will.

"Yes, Your Majesty, Weichen will go and arrange it."

Jingzhao Yin Xiaojiong was very active, and when he heard that Li Longji asked for an increase in the number of lighting braziers, he hurriedly went to implement it immediately.

"Xiao Fuzun, wait a minute."

Li An opened his mouth to stop Xiao Jiong, and looked at the emperor, and said: "Your Majesty, blindly adding the number of braziers can't change much brightness, and it consumes very charcoal and firewood, Weichen is inventing a more energy-saving electric lamp, I believe it can be developed soon, and when the time comes, the streets will be ten times brighter than now, and this thing is not afraid of rain, which is more convenient and economical than using a brazier." ”

"Electric light? Can make the streets ten times brighter than they are now? ”

Li Longji's eyes were full of surprise, and all the ministers also cast complicated and curious glances at Li An.

It is inevitable that any item that has not appeared in this era will cause a great sensation if it is suddenly proposed.

However, Li Longji and the ministers were also even more curious, they couldn't figure out where Li An's good skills came from, and why did he have such great skills at such a young age? At least in the eyes of Li Longji and the ministers, Li An's current skills can be regarded as heavenly.

Li An did not hide it, and told Li Longji and the ministers about the development progress of the electric lamp, and said that he could come up with the product within half a month at most, and soon carry out mass production, and then further improve the design, so that the electric light can be used in various equipment such as steam trains and steam passenger wagons.

Through Ang Lee's detailed description, Li Longji and the ministers gradually understood the principle and function of electric lights, and looked forward to Ang Lee's research as soon as possible.

Li Longji had even planned that as long as the electric lamps mentioned by Li An were successfully developed, all the braziers on the streets would be replaced with electric lights immediately, and a large number of electric lights would be installed in the palace, so that in the future, when he walked around the palace at night, he would not need the palace maid to carry lanterns to open the way.

Moreover, when the palace becomes brighter, it will be much easier to keep it safe, after all, once the assassins and thieves infiltrate the palace, they will definitely use the cover of night to move around, and if a large number of electric lights are installed, these rooster and dog thieves will have nowhere to hide, thus greatly increasing the security of the palace.

"Li Shilang will go back and study it carefully, and after it is done, he must tell me as soon as possible, I really want to see what this electric light will look like after it is built, and whether it is really as good as Li Shilang said."

Li Longji asked very excitedly.

Li An smiled slightly: "Your Majesty, rest assured, Weichen will do his best, and after he is done, he will definitely inform His Majesty as soon as possible, so that His Majesty can see the effect of the electric light." ”

For the invention of electric light, Li An is full of confidence, now the technology of manufacturing iron wire and copper wire has been very mature, the process level of Yaoyu has also improved a lot, tungsten wire was successfully manufactured not long ago, so that the manufacture of electric light bulbs will not be much difficult, and the wire is not a problem, only need to make copper wire, in order to insulate the top of the cloth can be wrapped.

As for the generator, in fact, the principle is not complicated at all, it is some simple structure, you need to make magnets and copper wires, just add it, in addition, you also need to provide power for power generation, the steam engine can provide enough power, and there is no problem in lighting the electric lamp with the amount of electricity.

The type of generator that Li An is currently developing can drive thousands of bright electric lights, which is enough to meet the needs of a whole road, of course, in order to save the line, Li An is ready to prepare a generator for a workshop, so that the copper wire can be saved to the greatest extent.

The importance of each square is different, the first thing that needs to be satisfied, of course, is the east market and the west market, and secondly, the square near the imperial city, after these are satisfied, the southern square can be considered.

In addition, if Li Longji needs it, of course, it must be prioritized in Daming Palace, Xingqing Palace and Taiji Palace, in addition, there are R&D centers outside the city, as well as his own annexes, which need to be given priority.

The generators of each square, one is enough, the smaller ones, one generator can meet two or even four squares, and in the Daming Palace and Taiji Palace, as well as the research and development center outside the city, as well as the railway station, more than two generators are needed, one is because the area of these places is relatively large and more important, more electric lights are needed, and the other reason is just in case, once one generator fails, the other can continue to supply power, so as to ensure the beauty and brightness of these areas.

In these important areas, in order to ensure the reliability of lighting, the lighting lamps of each generator are staggered, so that after a generator fails, it will not have much impact on the whole area, that is, the brightness becomes weaker.

For the reliability of the generator developed by himself, Li An is absolutely full of confidence, as long as there are no special circumstances, the power generation device will not be damaged, and the steam engine that provides power for the power generation device is likely to be damaged, for this reason, in important areas, Li An will equip the power generation device with double steam power, after one breaks, the other can continue to work, in order to provide a more reliable guarantee.

Once all the inside and outside of Chang'an City are connected to electric lights, it will greatly enhance the international influence of the Tang Empire, and the envoys and businessmen of various countries, as well as students from all over the world who go to study in the Tang Dynasty, will be completely shocked by the advancement and prosperity of the Tang Dynasty, and will not hesitate to devote themselves to the nightlife of the Tang Empire, so that they will not be able to extricate themselves, and even never want to leave.

For this expectation, almost all the ministers saw it, and were proud that they were a member of the Tang Empire, and even admired Ang Lee's super skills, and regarded Ang Lee as a god.

A few days later, the generator and the incandescent light bulb that Ang Lee had been concentrating on were built successively, and when they were tested, they were very successful.

In order to verify the durability of the tungsten light bulb and the reliability of the entire generator set, Li An let them continue to run until an hour later, seeing that there was no problem with the light bulb and the generator set, he sent his subordinates to Daming Palace to tell Li Longji the news of the successful invention of the electric light.

"Li Shilang, this guy is amazing! Brighter than a torch, how did you come up with such an ingenious thing? ”

This is not the first time that the craftsmen have raised such questions, their culture is generally relatively low, and their vocabulary is slightly insufficient, and only by adopting this surprising question can they express their inner admiration and admiration for Ang Lee.

"Read more and learn more, and you will naturally be able to think about it."

Of course, Ang Lee won't tell the truth, this kind of thing can't be said at all, so he can only find a reason to perfunctory the past.

When Li Longji heard the news, he was greatly excited, and immediately asked the person who reported the basic situation of electric lights, and after learning that electric lights were indeed brighter than torches, he laughed happily.

Li Longji wanted to go to the R&D center immediately to see what the electric light looked like, but he was persuaded by Yang Yuhuan beside him, because it was still daylight, and it would be better to see the effect at night.
