"Master Chen, what the hell is this, explain it to this king!"

Li Er was excited, and immediately grabbed Chen Xu's collar, and his face turned red with excitement.

No wonder he wasn't excited, but it was so much that after he went back that day, he dreamed of the kind of light that could completely illuminate the night.

It's too bright, too dazzling, too convenient, where can Datang's current lights be compared, and there is no comparison at all.

For him, a connoisseur of marching and fighting, he was deeply troubled by the problem of the lights at night, and he really felt that the lights were too dim.

If it's a normal life, the lanterns hanging around you, the lit stone lamps, the candles or something are just that, it's good to illuminate the surrounding environment, and there's nothing harsh.

But both armies carried torches on the march and in battle, and to be honest, both sides were no different from blind men, and the illumination of the torches was limited, not to mention the daily march, exploration, and encampment.

When the two sides are glued together, each waving a torch, in the chaos can not see anything clearly, the torch is a little far away is like being blind, often hurting his own people.

If there is this bright light, there is a special person in charge of lighting, and everywhere it shines, the battlefield is white, and it is clear who is fighting and who is fighting at a glance, it is definitely much better than the previous experience.

Not to mention anything else, even if he usually walks at night, the light shines far away and illuminates him for dozens of steps, which is not much cooler than using a dim candle lamp.

Several other people also reacted similarly, or a few civil officials hurriedly shouted for everyone to refrain and asked His Highness to put Master Chen down first.

Chen Xu was speechless and was put down by Li Er, who came back to his senses, looking at the excited appearance of the room of people, he was very depressed.

He shared this flashlight with Aaron after he got it, and he really didn't show it to you, but don't be so excited.

Of course, he also understands everyone's feelings, after all, he was the one who was deeply troubled by the night before, otherwise how could he beg the system to come up with this thing.

There is no flashlight production line, and after he completes all the tasks, it will be open for exchange, but it is enough, he can't let too many people have this kind of thing.

After all, the flashlight will be very convenient to act at night, if it falls into the hands of the prince's gang, or some kind of opponent, killing people and escaping at night, wiping the neck and stealing or something are too powerful to prevent.

"Don't get excited, this thing is precious, I still have a few in my hand, you can take it and play slowly."

Chen Xu exchanged four flashlights in one breath, a total of two thousand civilization values, which was nothing compared to the civilization values obtained by the city wall.

"It's turning this thing on during the day, absorbing the sun's rays as an energy source, converting the heat energy of the light into something called electricity, and then turning it on again, you can start consuming electricity and making it convert it back into light."

Chen Xu said, it is much simpler than explaining to Aaron, and it is also to prevent trouble, otherwise he will have to explain more and have a headache when he is asked.

"It's amazing, it's incredible!"

Li Er turned on the flashlight with a snap, and the light shone out, making half of the wall snow-white, he shook it with his hand, and found that as long as his fingers blocked the place where the light came from, he could cast a shadow behind him, and it was indeed from this port that the light was shining straight out.

He shone into the distance, and it was illuminated more than ten meters away, and even farther away, it could leave a faint light.

"With this thing, we will have a powerful war artifact in the field of our army! The guards also have a sharp weapon at night, which can better perform protection tasks! ”

The eldest grandson Wuji was also playing with it, and it was hard to hide his excitement, they both saw the preciousness of this thing and understood its preciousness.

The scientific and technological content and complex mechanism contained in this are no longer clear that can be explained by humans and ghosts, and they have a further understanding of Master Chen's talent and mystery.

Chen Xu's status in their hearts is getting higher and higher.

"Okay, these four are for you, remember not to be stolen, if this thing falls into the hands of the prince, it is not a joke."

"When the time comes, the prince's master will come to the starry night with this thing, and if you don't do it, you will be able to kill all the way to Your Highness's bedroom." Chen Xu scared Li Er.

Li Er said that he had already considered the situation that Chen Xu said, and would naturally protect it.

"Can I send one from my father?" Li Er asked.

Chen Xu said in his heart that when he went to see him today, he was going to give it to him, because the other party was too enthusiastic and forgot, you said could you send it.

After receiving a positive reply, Li Er had already thought about the ownership of the four flashlights, keeping one for himself, one for the princess, one for his father, and the remaining one for Wuji, if they wanted to play, they would go to Wuji.

Chen Xu said with a smile: "This thing is very troublesome to make, time-consuming and labor-intensive, and it is difficult to have more in a short period of time. ”

Everyone nodded their heads, looking forward to it, really looking forward to it, without a trace of fraud.

In fact, if Chen Xu wants this thing, it is simple, and he can change dozens of them in one go now, but there is no need, it is indeed very expensive, and it also plays a very big role in Datang, so it is better to flow out less.

Tonight was simply a carnival for Li Er and the others, and when Chen Xu finally said that he planned to get two for the city wall to patrol the city wall to prevent it from being destroyed, he was even happier.

When the matter of the wall is over, will it not be his possession again?

For a character like Master Chen, it's impossible to take back what he sent out, right?

Charge during the day and use it at night, and according to Master Chen's clear statement, it only takes less than two hours to complete the charge, as long as it is not too rainy weather, as long as it is not used all night at night, it can be used for several days.

This is equivalent to saying that it can be used unlimitedly, which is great, and he will never have to worry about hurting his eyes because the candle flame is too dim when he is immersed in reading at night in the future.

By fixing this thing and shining with light, he can read and write all the time, and the light is bright and does not hurt his eyes, and he can carry it with a pleasant experience.

When I'm done, turn off the lights and stuff them into my sleeves, in my clothes, sleep in my clothes, and protect myself closely, just like the dagger by my side, is there anything better in this world than it?

If there is, it must be another flashlight.

The carpenter was still very good at his work, and by the time the night market opened, four simple folding tables had been built, and although the chairs had not yet been built, they provided enough convenience.

It wasn't until the curfew was about to be curfew that Li Er and the others left with a smile, said goodbye to Master Chen, and went back to their respective homes.

As soon as Li Eryi arrived home, he went straight to the back house, found a few sons, handed them a flashlight to play, and by the way, called Guanyin and Concubine Yang's wives.

"Father, is this something that Master Chen has researched, it's amazing, it can capture light!"

Li Tai and Li Chengqian were all crazy with joy, and their favorite daughter Li Lizhi and several girls were also crazy together, chasing and playing in the backyard, and the light shone everywhere, shining everywhere.

The light shot out, like a white pillar, shining into some of the dust floating in the air, which looked very obvious from a distance, really as if the light was released alive.
