Different people's reactions and gains after seeing something or experiencing something are completely different.

Since the beginning of human beings, there have been 10,000 people who have been hit by apples, but 1,000, right?

But only Newton thought of gravity from this.

Anyone who walks on the sea can basically realize that the first thing they see in the distance is the mast, but who would associate this with the fact that the earth is round?

Not to mention the interpretation behind natural phenomena such as rain, wind, and lightning.

"Huaiying, you can see this, I'm very happy for the teacher. It just so happens that I have some ideas for this useful ignition mechanism, and you can see how to put it into practice. After all, no matter how much you say, it is not as convincing as it is to come up with something real. ”

Although Di Renjie has shown enough wisdom and ingenuity so far, there are not many things that can be used.

Li Kuan can now be regarded as adding some chips to him.

"Master, do you have a good idea again?"

When Di Renjie heard this, his heart was happy.

In the past few years, he has found out.

As long as my master has any new ideas, there will be something in this world that has never existed before.

Now this new ignition mechanism, Di Renjie is full of expectations for it.

"Whether it's good or not, you won't know until you make it. In this way, you can take this sketch to the staff for a look, and the principles and everything have already been written on it, and it depends on how you implement it. When the time comes, after this ignition mechanism is made, if the effect is very good, we will directly increase the publicity efforts and let it enter thousands of households in the shortest possible time. ”

"Master, don't worry, at most, I will be able to take out mature samples in half a month, and I will not be ashamed of you when the time comes."

Di Renjie quickly looked at the sketch in Li Kuan's hand and had a preliminary idea of this thing called a lighter.

Compared to the steam engine he is currently studying, the lighter is basically as difficult to make as playing.

With the experience he had accumulated during this time in the Steam Engine Research Institute, it was not difficult to make a lighter.

It's just that Li Kuan hopes that it can be used normally in the case of wind and rain, so it is necessary to consider the structural design carefully.

……

The Gewu College of Weishui Academy was newly established last year.

If you want to talk about fame, there is naturally no way to compare it with the Gewu College of Guanshishan Academy.

However, after all, the eldest grandson family and the Zheng family are both old families, and the industries involved in the family are also very extensive.

In particular, the iron smelting and ironware building of the eldest grandson's family, except for the Chu Wangfu, which can overwhelm him, ranks second in the entire Tang Dynasty and even in the entire world.

With these accumulations, as long as they truly change their concepts and support the development of Gewuxue, there are still a lot of things that can be done.

This time, "Datang Daily" and "Chang'an Evening News" both published the announcement of the reward of the Datang Royal Military Academy, and Changsun Chong came to Weishui Academy in person, wanting to take this opportunity to let the Gewu Academy of Weishui Academy also attract everyone's attention.

"Lang Jun, the reason why the Datang Royal Military Academy is not satisfied with the current fire fold is mainly because when it is in the field, especially when it is windy and rainy, it is difficult to ignite the fire fold, and it is even easy to completely extinguish the fire. Our academy is ready to abandon the idea of fire folds and find good solutions based on the more ancient principles of flint and steel. ”

In Weishui Academy, Changsun Chong listened carefully to Yu Wenshan explaining their research direction to himself.

As a master craftsman personally invited by the eldest grandson Wuji, Yu Wenshan, as a close disciple of Yu Wenkai, a master craftsman of the Sui Dynasty, although he has only learned the technology of Yu Wenkai for less than ten years, but relying on his super comprehension ability, he has learned Yu Wenkai's technology.

Moreover, unlike Yu Wenkai, who is proficient in city design, Yu Wenshan is more interested in specific process improvements.

Now in his forties, he is at the peak of his craft.

"Yuwen Teaching, the reason why this flint is not popular in Chang'an City is because it is more difficult to use it for fire. Even if it can be used in windy and rainy conditions, the effect is very poor. Will this really work? ”

Eldest Sun Chong originally thought that Yu Wenshan would come up with a plan for his eyes, but he didn't expect it to be so mediocre.

Wouldn't the idea of taking the opportunity of the reward offered by the Tang Royal Military Academy to start the name of the Gewu Academy of Weishui Academy be ruined?

"Ordinary flint and steel, naturally, will not work. However, if you can find a special flint and steel, and then use the lighter bar as a consumable with the help of a special lighter, it may be much easier to make the flint and steel fire.

When I was doing research in an ironmaking workshop before, I found that sometimes the iron slag that was scrapped from ironmaking was prone to sparks when it collided. Yesterday I went to the iron-making workshop again, found various samples and tried it, and basically confirmed that the solution of using this special iron slag to press into flint and steel, and then match it with a suitable lighter, is completely feasible. ”

Yu Wenshan, as an authority in the Gewu Academy of Weishui Academy, naturally has a few brushes in terms of technology.

Otherwise, there would be no need for the eldest grandson Wuji to personally come forward and invite him to come to Weishui Academy as a teacher.

In fact, Yu Wenshan's plan is a little similar to the flint and steel in the outdoor equipment of later generations.

The flint and steel of later generations are basically man-made alloys, and the main components are iron, magnesium and rare metals.

This kind of flint, as long as the chemical ratio is set reasonably, can almost play the same role as a match or a lighter.

Moreover, compared to matches and lighters, the storage conditions of this flint and steel are much lower.

Even if it falls into the water, it won't break.

Even if you fall on a stone, you don't have to worry about it breaking.

"I heard that many craftsmen in Chang'an City are very interested in this reward, and even some workshops have set up special staff to work hard for this reward. Although the amount of this reward is not large, everyone understands the meaning behind it. ”

Although Changsun Chong understood what Yu Wenshan said, he obviously didn't have much confidence in whether he could make such an ideal flint and steel.

In his opinion, if you can make a fire fold that can be used normally when it is raining and windy, such a plan is the safest.

"The Tang Royal Military Academy, that is where His Majesty personally serves as the dean, and the reward they gave out is naturally extraordinary. Lang Jun, don't worry, this time, this flint and steel of ours is already a blockbuster! ”

Yu Wenshan is obviously very confident in his new discovery in the ironmaking workshop.
