In the third month of the lunar calendar, after the rainy season.

The wheat and rice in the fields have been settled, and various follow-up water conservancy facilities are also progressing steadily.

The agricultural matter was well solved, and after a few large landowners were settled, the rest of the people did not have much opinion on the redistribution of the land, anyway, as long as they could continue to farm.

As for the replacement of crops, under the majesty of the army and the king, the opposition gradually disappeared.

The iron factory that Wang Lanling was concerned about also made the first batch of iron nails.

Iron gold stood beside Wang Lanling, looked at the iron nails that were pressed out by the iron stone and said: "Now there are still some problems with this machine, if you do more every day, you can make two thousand iron nails, which is not much." ”

Wang Lanling picked up an iron nail, and after looking at it carefully, he found that the quality of these iron nails was not very good.

Wang Lanling said: "The price of iron nails can't be too expensive, if it's too expensive, no one will use it, and the selling price should be less than a penny, at least five cents to buy a big bag, a pack of two or three catties." ”

Tie Jinqi quickly calculated the cost and said: "Then our current output for this day can't be sold for ten yuan, but the coal money and iron money alone are dozens of yuan." ”

Wang Lanling looked at the iron gold, "That's why you want to continue to improve the machine, the current problem is still the problem of production technology, we don't have such a good mold, but this production speed can still be improved, and the equipment that is neatly pushed can also be changed to electricity." ”

"I don't understand why the electricity through the copper wires can push the wood around. ”

It's easier for everyone to understand the matter of generating electricity through motion, but they can't understand the fact that a wire is put on it, and another heavy copper and iron guy will turn it on its own.

Wang Lanling didn't explain what electromagnetic induction is, so even Gong Yueman was very confused about many things.

In fact, many things are like this, I don't understand the principle, but it doesn't hinder the application.

Wang Lanling doesn't particularly understand it, and he doesn't specialize in this.

"As long as it can be used, there is no problem with the production of iron nails at the moment, but how to mass produce and continue to improve, we must do it as soon as possible."

Iron gold said: "Except for nailing coffins, there are not many places where this is usually used, right?" ”

Wang Lanling said: "Nonsense, many places use this, don't just go to small places like Heishui County and Shanhai County to have this kind of wishful thinking, there are many places with iron nails outside!" ”

However, in fact, it was Lord Wang who remembered the mistake...... The people of Muzhou buy rivets, although they are called rivets, but they are actually big wooden nails that nail the rope of the tent, the kind wrapped in iron sheets.

In this era, all tenon structures were used, that is, carpenters who stuck to each other, and there was not a single iron nail to be found in a classical house.

Muzhou people who can't even afford to use iron pots, where do they have the money to use iron nails?

Lord Wang is always high, there are few places to be grounded, and he always has no practical experience of some things, so when he understood this fact, he found that the iron nail factory had invested a lot......

It's not that when iron nails are not used, the coffin board can be nailed, this is just needed.

Although Tie Jinqi is a cultural person, he really does not have the knowledge of Wang Lanling, and he has not been to a big place like Tongzhou, so at this time, he feels that he really has little knowledge.

"There are so many places outside where nails are used, and the nails must not be ground out one by one, what kind of technology do they use?"

Iron Jinqi looked at the crushing machine in front of him suspiciously, and he felt that the machine he had built to press iron wire into nails was too backward.

However, the iron nails outside are really ground out one by one, after all, the nails that press the coffin board for the princes and nobles are always finer.

Wang Lanling said: "Look at the two ends of this iron nail, one side is sharp, and the other side is flat, so if you want to cut and press a nail into this shape, there must be a rule. ”

Tie Jinqi looked at the iron nail and asked, "What law?" ”

This is the wrong question, Wang Lanling said directly: "You have to think about this yourself, where do you see where there can be improvement now?" ”

Tie Jinqi thought for a while and said: "I feel that it is not good to cut the wire, sometimes and constantly the wire, and then the wire is easy to break, these wires are too brittle. ”

Wang Lanling said: "Indeed, our iron-making technology has not risen much now, and there is still a gap compared to Heishui County, but this is also slowly improving, and we will build a steelmaking plant in the future." ”

Tie Jinqi asked, "My lord, isn't the coal mine still unsettled?" At the moment, we are still using the salaries distributed by the imperial court. ”

The imperial court gave many benefits to officials, including ice charcoal benefits, and the coal mine for heating was one of them.

Wang Lanling bought some things from the county guard, and basically used his own things to exchange for the county guard, and there was no shortage of coal from Lord Jiang, and there were coal mines in the territory under the jurisdiction of others.

It's just that outsiders didn't do business with people here before, and the county guard was bent on returning to his hometown, so he didn't take care of this industry.

The consumption level of Shanhai County is like that, everyone burns cow dung, sheep dung and straw branches, and whoever burns their brains to buy coal.

Everyone lives a small life, and no one pays attention to the county guard.

It is equivalent to a second-generation Beijing who was sent to a small ravine in the poor countryside, and he did a woolen business?

No one else plays with the county guard, only Wang Lanling goes to the county guard to buy things, and goes to get good things for some things that the county guard has, so the relationship between Wang Lanling and the county guard is still very good.

Shanhai County is still short of coal, but it is not so short of coal.

"The coal thing is not a big problem, the big problem is how to improve the production technology, at present, Gong Yueman has used electricity to decompose hydrogen and oxygen, and I also asked people to study this, physics and chemistry are best developed together."

Since Wang Lanling pointed out power technology, there is no reason not to use chemistry and physics.

Only with the development of various infrastructure can we truly enter the era of electricity.

Of course, communication technology is not daring to point out, and this is actually very easy to point, because the telegraph appeared much earlier than the electric light.

Faraday established the law of electromagnetic induction in 1831, but there were attempts to invent the telegraph before that, and it was not until 1837 that someone made a reliable telegraph, and in 1879 a reliable electric light appeared.

Therefore, the relationship between electricity and communication technology is really a matter of stepping in the door, and Wang Lanling does not dare to explain what electromagnetic induction is.

Once the communication technology is improved, then the empire will enter a new era.

Stronger control will lead to more intricate development, and Wang Lanling does not know whether it is a good thing or a bad thing for him, at least for now, he is unwilling to give that kick.

Although Wang Lanling did not provide any substantive advice, Tie Jinqi still thought about how to improve this nail pressing machine according to Wang Lanling's guidance.

Fortunately, this era is not really ancient, and the emergence of guns has led to the improvement of many industrial technologies.

Iron and gold objects have always been made of the kind of devices that do not require a large number of parts, and these parts are cut by large machines and then polished and repaired by workers.

At present, Wang Lanling's needs are very special, what he wants is the kind of technology that can quickly make a large number of things, but he doesn't care much about the quality of the product, and he doesn't need that particularly delicate thing.

It is obviously a delicate and high-end thing, but the feeling of iron and gold is that Wang Lanling replaced the demand for briquettes to make clothes.

Tie Jinqi kept thinking about improvement plans in the office, while Wang Lanling went to the textile factory to continue to beep with people.

"This, although it is almost the same, there is still room for improvement."

Although Wang Lanling does not know much about textile technology, he knows what kind of price and quality can impact the market.

"The windmills in Heishui County are already backward production capacity, and if we want to make a large number of textiles in Shanhai County as fast as possible, we need to use electricity and the most advanced electric textile machines!"

When he was in Heishui County, Wang Lanling did not exert his full strength in many places, but in this Shanhai County, Wang Lanling was the guide of all his strength.

At present, in addition to iron ore and copper mines and a few factories in Shanhai County, most of the rest have become electricians in the new era!

In the square of Shanhai County, there are five or six thousand electricians providing electricity intermittently every day, and the work efficiency of these people is much higher than that of wind and hydropower!

If Wang Lanling can become the county magistrate of Heishui County after graduating from the official school, then it is the electrician of Heishui County who provides kinetic energy for the textile mill now.
