Chapter 389 The City That Never Sleeps (Please vote and subscribe)

Besides power machinery, another key factor that has always restricted human productivity is time. In the long dark night, being unable to do anything is simply a waste of life. If the night time can be used reasonably, productivity can at least increase by 20%.

And there is nothing else that can solve this problem except lamps. Although the Han tribe now has oil lamps, the weak flames are of no use at all. If it is cloudy and there is no moon, the whole city will still be pitch dark at night, not to mention finding things to do at night.

So Luo Chong decided to make a new lighting device to replace the current oil lamps. Uh, but the new device seems to be an oil lamp. However,

unlike the previous lamps that directly inserted a piece of wool into the oil, the lamp that Luo Chong wanted to make this time is a glass-covered kerosene lamp that was very popular in the early days of the founding of our country. Compared with candles and ordinary oil lamps, this kind of lamp called "horse lantern" is not only rainproof and windproof, but also easy to carry and bright enough. It is definitely a major device worth developing.

This is by no means a fantasy. The Han tribe is now absolutely capable of processing such artifacts. The materials have been gathered. Crystal can be used as pure silica to burn glass, and the oil pot and lamp holder can be directly welded with copper plates. This may not be easy to do before, but it will no longer be a problem with lead.

Mixing tin with a melting point of more than 200 degrees and lead with a melting point of more than 300 degrees into an alloy is the best solder at present. The melting point of this lead-tin alloy is not higher than 300 degrees, and it takes into account the adhesion of lead and the hardness of tin. The ductility is also very good, and it can be processed into very thin welding rods. When working, just put a soldering iron in the furnace and heat it directly to more than 400 degrees, and you don’t even need to burn it red. Then take the welding rod and soldering iron and push it directly on the seam. It is no different from modern electronic soldering, but the way the soldering iron is heated is more primitive.

This welding technique is very simple, but very practical. It is a piece of cake to use it to make a sealed oil pot. Of course, the container made by this welding method is not resistant to high temperatures, but the oil pot at the bottom of the kerosene lamp does not need high temperatures. After all, the flame is above the lamp mouth, not directly burning in the oil pot below. It doesn't matter whether it is resistant to high temperatures or not, as long as it does not affect normal use.

Finally, there is kerosene. Although the Han tribe cannot get it at present, it is the same to use tung oil. It is just for lighting, and it doesn't matter what you use.

In this way, the three most important parts of the "horse lantern" are all solved, and it is only a matter of time before it is manufactured.

However, since he thought of the lamp, Luo Chong suddenly remembered a more environmentally friendly lighting method, that is, the luminous plants unique to this world. Except for the trip to Rumeng Water Valley two years ago, Luo Chong has not been there for a long time.

The dreamlike scenery has made him particularly addicted to it. Since he has no time to go, he might as well move Rumeng Water Valley here.

Imagine if all the streets in Hanyang City were lined with luminous plants, how beautiful it would be at night. The tall willow trees would flutter in the wind like LED light strips, emitting pink and white fluorescence. If some flowers and plants that glow at night were made into green belts, even street lights could be saved. It would be truly energy-saving and environmentally friendly.

Not only that, compared to the hot daytime, many people like to enjoy the cool at night, but due to the pitch-black darkness, they would rather stay in the stuffy house. Luo Chong guessed that these primitive people might have just changed, and they still haven't forgotten the fear of darkness in their bones, just like they had to go back to the cave when it got dark.

But now they are in a safe city, without any beasts or enemies. If they can "light up" the entire Hanyang City, there will definitely be tribesmen who come out to enjoy the cool in the cool evening. As for the rich nightlife, even if Luo Chong does not deliberately develop it, the tribesmen will develop their own entertainment methods, which is definitely a very good way to relax for the tribesmen who have been tired all day.

The more Luo Chong thought about it, the more he felt that this method was feasible. He even developed more uses for luminous plants, such as luminous potted plants, which could be placed in the house as a night light that was always on. Although it was not very bright, it was absolutely no problem for people to see things in the house clearly at night. The most important thing was that once this method was successful, it could save a lot of candles and tung oil.

It was simply invincible. Moreover, these luminous plants could not only facilitate people's lives, but also greatly improve the happiness of the tribesmen. It was like one person lived in a mountain bungalow without water and electricity, and the other lived in a beautiful scenic park. Of course, the people living in the scenic area were in a better mood!

If possible, Luo Chong also wanted to live in Rumeng Water Valley every day, but the environment there was not suitable for growing crops, unless all the luminous plants were destroyed and turned into farmland, but that would be too wasteful, so he had never set Rumeng Water Valley as a place to live.

But now it is the same. If this plan can really succeed, it would be equivalent to artificially building a Rumeng Water Valley, which would be too beautiful.

In addition, the planning of night-light street lamps should also be spread to the new city as soon as possible. In the future, all the territories of the Han tribe should say goodbye to darkness and live a wonderful night life from now on.

Luo Chong put down the drawing of the "horse lantern" and excitedly came to the main house to tell Xiaodie about his idea. Xiaodie was immediately excited. They both went to Rumeng Water Valley at the same time, and then they never had the opportunity to go there again. Now they heard that Luo Chong was going to plant a large number of those luminous plants in the city, and happily hugged Luo Chong and turned around

.

After the two of them made a fuss for a while, Luo Chong was also ready to go out to find someone to complete his plan. However, after thinking about it, only the Snake Clan was suitable for this task among the residents of Hanyang City.

Whether it was the leader of the Snake Tribe or the elders of the Snake Tribe, they had been to Rumeng Water Valley more than once, and they were very familiar with the route and terrain. Another point was that the Snake Tribe was good at digging and making various herbs. In other words, they had a lot of research on flowers and plants. Now asking them to dig those luminous plants was just the right professional match.

However, before Luo Chong went to the chief of the Snake Clan to arrange this task, a letter was delivered to him by a flying eagle sent by You Fu.

"Chief, You Fu sent a letter, and with the letter there is also this bamboo tube, which feels quite heavy. It may contain something." Ying Rui personally brought the letter and the bamboo tube to Luo Chong.

Luo Chong immediately opened the bamboo tube, and the contents inside immediately made his eyes widen. He didn't expect that they were all seeds of crops, and there was actually such a thing?!
