Chen Xu said that he doesn't need any slipper production line, and he still has a bunch of tasks to complete.

However, the task was issued, and he had to work hard to complete it.

So how should the night lighting situation be improved, and how can the night market be changed to make people satisfied?

Is it possible to invent the electric light? No, the invention of electricity is very troublesome, and to make the lights in the restaurant not only need a generator but also a light bulb, how can he be given such an excessive task at once.

Therefore, is it to improve the lighting situation with the help of the current situation of Datang?

Because of the help of people, Alun has nothing to do for the time being, she is mainly responsible for Chen Xu's daily life, at this time she is sitting in her room, holding a bronze mirror in her hand to shine on her face, and is carefully smearing something on her face.

After admiring Aaron's beauty for a while through the unclosed door of the room, Chen Xu suddenly realized, yes, the mirror.

Anything that can reflect light can make the light brighter visually.

Put a lantern in a room, and if there are mirrors around it, then each mirror will reflect the light of the lantern, so that the house will be very bright.

That's why a white room is much brighter than a dark room with the same light.

Many of the buildings in the imperial city are resplendent in gold, and this is also the principle.

Under the reflection of the light, the large-scale festival can become a roaring and spectacular light, not only visually clearer and farther, but also has a shocking effect.

In this way, you can buy some bronze mirrors, and consider using more reflective utensils, and even the table top can be replaced with a smoother wood material, and apply a layer of reflective paint on it, which is all old furniture anyway.

was so happily decided, so Chen Xu began to go out again.

After learning that there was someone around him to protect him, Chen Xu was also very satisfied, the security in this ancient place was not very good, and it was safer to bring bodyguards, so he took Arun with confidence on this trip.

Alun didn't want to stay in the restaurant every day, and she was in a good mood, so the two first walked around Xinghuafang, and finally came to the West Market.

After purchasing a large number of bronze mirrors, lanterns and candles, and finding a large cannibal shop, I found lacquered wood with good reflective conditions, which can be used to make tabletops.

In the afternoon, after the number of guests decreased slightly, he began to let everyone be busy with the placement, first the first floor, then the second floor, and the amount of work was not small.

Fortunately, everyone was ordered to forbid, and it was not too troublesome, and at dusk, it was quickly installed.

"Okay, when the time is up, you can light the candles, and I'll go out first, and see the lighting when I come back in the evening."

Chen Xu said, the night market is temporarily impossible, although the curfew in Chang'an City at night is still late, and people still have some time to come out to play after dark, but there is no energy to arrange it today, so they can only wait for tomorrow.

He still rushed to the Qin Palace, he was more concerned about the multiplication table of 10,000 people, and by the way, he wanted to teach the three of them.

In fact, the basic things, poems, songs, etc. are taught by Kong Yingda, Chen Xu is a modern person after all, and he has a lot of knowledge, and he can tell the three of them anything he wants.

And the custody made the three of them listen to it with relish.

For example, what Chen Xu said about the African savannah today, there are too many things that can be said in that place, which can open up the three of them's knowledge and imagination.

After the business, he came to Li Er, only to see Li Er and the others frowning again, obviously encountering something troublesome.

"What's going on here? Is the prince in trouble? Chen Xu asked subconsciously.

Li Er smiled bitterly: "Master Chen is really like a god, isn't it, we have stolen a few bags of cement that we placed on the edge of the city today, and no one dares to steal things guarded by sergeants inexplicably, unless it is him." ”

"We were worried that he would find a weakness in the cement and use water to destroy all the cement in our warehouse."

The eldest grandson Wuji sighed, thieves can't be guarded against, let alone the prince with great energy.

"There's no need to rush this matter, by the way, have you told Your Majesty about the stir-frying, you have improved the cooking skills of Guanglu Temple, and the satisfaction of the stomach is easy to make people feel happy."

Chen Xu asked.

Li Er shook his head: "I forgot about this matter, since Master Chen said so, then we will report it tomorrow." ”

Chen Xu nodded: "In this way, we often give Your Majesty a little surprise, and we can slowly move his partiality towards the prince back, and then King Qin can continue to please his father, but the prince can't do anything, only say some flattering words, and take some treasures to counterclaim." ”

"It doesn't matter who is better or worse."

Chen Xu is a bit suspicious of talking about the crown prince, but this is nothing at all in the Qin Palace, let alone his identity at this time.

Everyone nodded, so this matter still has to fall on Master Chen.

The eldest grandson Wuji and the others know the truth of killing people with a slow knife, and speaking of Li Yuan's bias towards the two, isn't it because the King of Qin has been fighting abroad all the year round and has allowed the crown prince of Qi to say some slander in front of him from time to time?

As long as King Qin's side can really please him from time to time, with Li Yuan's character, it is almost inevitable that he will slowly lean towards King Qin.

As long as King Qin ensures that his position is not chaotic, the situation of the crown prince will slowly become dangerous, and he may jump over the wall in a hurry......

Everyone looked at each other and smiled meaningfully.

Their gazes at Chen Xu also became more respectful.

If it weren't for Master Chen, I'm afraid they would have already launched a mutiny and stained the imperial city with blood, maybe His Royal Highness King Qin would have been at his fingertips for the world at this time, but the loss of people's hearts, thinking about it now, still makes them shudder.

And Master Chen couldn't lift his shoulders or carry his hands, and he didn't understand the Four Books and Five Classics that the Tang people learned, but he was able to use a seemingly bloodless method to bring back King Qin's disadvantages little by little.

Thanks to the skin care soap sent to the palace again, Li Yuan is still a dragon face and a great joy today, and he said a lot of good things about King Qin in the early dynasty.

Even the few concubines they occasionally met on the road had greatly changed their lukewarm attitude from usual, and their attitude towards King Qin was much more eagerly flattering......

Thinking of the depressed and ugly appearance of the crown prince and his faction at the court, they felt happy in their hearts.

"By the way, I have something for you."

Chen Xu asked: "Do you have a way to promote this ninety-nine multiplication table on a large scale?" I need a lot of people who know and know how to use this stuff. ”

Popularize? Master Chen's request was very strange, but everyone didn't think much about it, after all, people thought that Master Chen was a person who did learning, and it was normal for him to want to promote his knowledge.

And this ninety-nine multiplication table is really not difficult, if it is promoted among some people with a foundation of knowledge, it is easy to learn.
