Different people have completely different reactions and gains after seeing something or experiencing something.

Since the beginning of mankind, the number of people who have been hit by apples is not 10,000, but a thousand, right?

But only Newton thought of universal gravitation from this.

People walking on the sea can basically realize that the first thing they see of ships 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, thunder and lightning.

"Huaiying, I am very happy that you can see this. It just so happens that I have some ideas about this easy-to-use ignition mechanism. You can see how to put it into practice. After all, no matter how much you say, it will not matter.

It’s not convincing enough to show anything tangible.”

Although Di Renjie has shown enough wisdom and intelligence so far, he still doesn't have much to offer.

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

"Master, do you have any good ideas again?"

Di Renjie felt happy when he heard this.

In the past few years, he has finally discovered it.

As long as my master has some new ideas, something unprecedented will appear in this world.

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

"Whether it's good or not, you won't know until you make it. In this way, you can take this sketch as a consultant. The principles and other things have been written on it. It depends on how you implement it. When the time comes, after the lighter is made, the effect will be very good.

If it’s good, we will directly increase our publicity efforts and make it available to thousands of households in the shortest possible time.”

"Master, don't worry, I will be able to produce a mature sample in half a month at most, and I will not embarrass you by then."

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

Compared with the steam engine he is currently researching, making a lighter is basically as difficult as playing.

Based on the experience he accumulated in the Steam Engine Research Institute during this period, it is not difficult to make a lighter.

It's just that Li Kuan hopes that it can be used normally even in windy and rainy conditions, so he needs to carefully consider the structural design.

…

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

When it comes to fame, it cannot be compared with Guanshishan Academy of Gewu Academy.

However, the Changsun family and the Zheng family are both well-established families after all, and their families are involved in a wide range of industries.

In particular, the Changsun family's iron smelting and ironware making, with the exception of the Prince of Chu's Palace, which could surpass them, ranked 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 geophysics, there is still a lot they can do.

This time, "Datang Daily" and "Chang'an Evening News" both published a reward announcement from the Royal Military Academy of the Tang Dynasty. Changsun Chong even came to Weishui Academy in person, hoping to take this opportunity to let the Weishui Academy's Gwu Academy also

It can attract everyone's attention.

"Lang Jun, the reason why Datang Royal Military Academy is dissatisfied with the current Huozhezi is mainly because it is difficult to ignite the Huozhezi in the wild, especially when it is windy and rainy, and it is even easy to completely flame out. Our academy is ready to abandon it.

Huo Zhezi's idea is based on the more ancient principle of flint and steel to find good solutions."

Inside Weishui College, Chang Sun Chong listened carefully as Yu Wenshan explained their research direction to him.

As a master craftsman personally invited by Chang Sun Wuji, Yu Wenshan was a close disciple of Yu Wenkai, a great master craftsman of the Sui Dynasty. Although he only learned techniques from Yu Wenkai for less than ten years, he relied on his super understanding ability to

He learned a lot about Yu Wenkai's skills.

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

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

"Yuwen Jiaoyu, the reason why this flint and steel is not popular in Chang'an City is because it is difficult to make fire with it. Even if it can be used in windy and rainy conditions, the effect is very poor. This really works.

?"

Changsun Chong originally thought that Yu Wenshan would come up with a brilliant plan, but he didn't expect it to be so ordinary.

Isn't my idea of ​​taking advantage of the opportunity offered by the Royal Military Academy of the Tang Dynasty to establish the name of Weishui Academy's Gwu Academy in vain?

"Ordinary flint and steel will naturally not work. But if you can find a special flint and steel, and then use a special fire bar and use the fire bar as a consumable, it will be possible for the flint and steel to make fire.

Becomes much easier.

When I was doing research in the iron-making workshop, I found that sometimes the iron slag used in iron-making can easily produce sparks when collided. I went to the iron-making workshop yesterday to find various samples for testing.

After some attempts, it was basically confirmed that it is completely feasible to use this special iron slag to press into flint and then use it with a suitable fire rod."

As an authority in the Weishui Academy of Geosciences, Yu Wenshan naturally had a few technical skills.

Otherwise, there would be no need for Changsun Wuji to personally invite him to come to Weishui Academy to teach.

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

The flints of later generations were basically man-made alloys, with the main ingredients being iron, magnesium and rare metals.

This kind of flint can almost function like a match or lighter as long as the chemical ratio is set appropriately.

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

Even if it falls into the water, it will not be broken.

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

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

.”

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

In his opinion, if he could make a fire breaker that could be used normally when it rains or winds based on the fire breakers, that would be the safest solution.

"The Royal Military Academy of the Tang Dynasty is where His Majesty personally serves as the dean. The reward they issued is naturally of extraordinary significance. Lang Jun, don't worry, this time, our flintstone will become a blockbuster even if it doesn't make a sound!
