Everyone is curious whether Zhu Yunwen can really make a lighter.
If he could really make a lighter, it would only prove one thing: Zhu Yunwen was incredibly talented.
After all, this was the first time anyone had ever seen a lighter from the Kingdom of Zhu Zi. The fact that Zhu Yunwen could name it showed that he was no ordinary person. The name was so direct and to the point that it seemed as if he knew a great deal about the thing.
The fact that he was still able to make it under these circumstances can only mean that he already knew how to make it.
Of course, another point is that everyone is paying close attention to this matter, for two reasons: firstly, it's something to watch and enjoy.
Secondly, if Zhu Yunwen can actually produce it and reduce the cost, it would be a good thing for all the countries present.
Just like the fire-starting tool shown by the prince of Zhu Zi Kingdom, it is indeed very convenient and has aroused great interest among everyone.
If this technology can be widely adopted, it will definitely be of great help to people's daily lives.
If something that is very likely to become a necessity is too expensive, then it is indeed not worth it.
In this situation, if Zhu Yunwen can control the costs and still produce the goods, then the problem of high cost can be solved.
This also allows them to buy lighters at a lower price, which is not necessarily a bad thing.
So for the princes and princesses present, this scene was something to watch as a spectacle.
If they fail, they will embarrass Zhu Yunwen. If they succeed, they can buy lighters at a cheaper price. It seems like they won't lose out; in fact, they will benefit. Why not?
The prince of Zhu Zi Kingdom was somewhat nervous, but despite his nervousness, he remained confident.
He felt that even if Zhu Yunwen could really make a lighter, it would not be as convenient as the one they had obtained after countless hardships and experiments.
They would never actually lower the cost further, but Zhu Yunwen, as a time traveler, is indeed very experienced in this area.
So in less than half an hour, the people he sent out had gathered everything he needed.
Zhu Yunwen looked at the materials on the table, and a smile unconsciously appeared on his face.
What he wanted was very simple: a small metal box made from a small piece of metal.
Then there was some cotton, and then a little bit of lamp wick.
These things are all very common.
What's less common is the flint. Although most people use flint, it's not common to see it being ground into a cylindrical shape as Zhu Yunwen requested.
In addition, Zhu Yunwen drew a small frame made of iron sheet on the previous drawing to fix the flint and steel and a small iron sheet at the bottom.
These things are almost like a lighter, made of some rather primitive materials.
Among these materials, one is of paramount importance: fuel.
Nowadays, the most common fuel is lamp oil. Initially, lamp oil was animal oil, but later it became vegetable oil because vegetable oil is relatively cheaper.
Later on, it became candles, and then kerosene.
Zhu Yunwen's lighter was made of vegetable oil, which could easily wet the wick and be ignited by a spark.
So Zhu Yunwen began making lighters. Although all the materials were laid out, no one could understand how the lighters were made.
Zhu Yunwen, have you thought about explaining this to everyone?
He quickly assembled the device, stuffed cotton into the small tin box, soaked the cotton in vegetable oil, put the lid on, and then assembled the small frame and flint.
Actually, this thing is really simple. Zhu Yuntong remembers that in the past, he and some of his friends often made lighters and similar things themselves.
Although the conditions are different now, it is by no means a problem to easily make these things.
After all, Zhu Yunwen had even managed to build guns and cannons, so a mere lighter would be a piece of cake for him, wouldn't it?
So, after assembling it, he would quickly make a lighter that was more exquisite, smaller, and looked better.
Zhu Yunwen held up the lighter in his hand, showed it to everyone present, and then said:
"Gentlemen, what do you think?"
At this point, the prince of Zhu Zi Kingdom was starting to panic.
After all, the lighter that Zhu Yunwen made was, at least in terms of appearance, clearly better than the one he was holding.
Moreover, judging from the parts and assembly of Zhu Yunwen's lighter, it was simpler and more effective than the lighter that the prince of Zhu Zi Kingdom had previously brought out.
But the prince of Zhu Zi Kingdom was clearly still a little unconvinced, and said:
"Although you have made it, it is still unknown whether it will be useful."
Zhu Yunwen smiled slightly and said:
"Try it and you'll see."
As he spoke, he placed his hand on the flint and steel, and then swung it sharply. The flint and steel was fixed on both sides, and as Zhu Yunwen swung it, it spun around and rubbed against the iron plate at the bottom, quickly producing sparks.
Next to it was a wick soaked in vegetable oil. When it came into contact with a spark, it ignited instantly. The flame flickered for a moment, then steadily rose on the lighter's wick.
