Although the grain purchased by Li Zhi was higher than the initial selling price, it was only two or three wen higher than the shipping fee.

This amount of money is not a matter at all in Li Zhi's eyes.

Not only that, but his approach also directly reminded Li Shimin.

Previously, for the sake of convenience, the imperial court directly handed over the task of collecting grain to the local influential clans.

Although this saves manpower, it also indirectly supports a group of middlemen.

The people did not get much benefit before, but gave most of the profits to the middlemen.

Li Zhi's method completely eliminated the exploitation of middlemen and directly benefited the common people.

Li Shimin thought of more than that.

If the local government collects grain directly from the people, it will be able to grasp the grain production more accurately.

This in turn facilitates the state's control of grain prices.

The imperial court could regulate the amount of grain supplied through the granaries built in various places.

It will not make grain prices too high because of insufficient supply, and it will also avoid excessive supply and causing grain cheapness and hurting farmers.

When Li Shimin took out his idea and discussed it with everyone, everyone once again sighed at Li Zhi's flexible mind.

At the beginning, everyone discussed the problem that had not been solved for a long time, and it seemed that there was no difficulty at all when Li Zhi came here.

Li Shimin and the ministers of the DPRK and China were overjoyed.

But those clans who were waiting to make a fortune hated Li Zhi again.

However, none of them impulsively wanted to assassinate Li Zhi this time.

Instead, he thought of a method that was exactly the same as Li Tai.

That is to make Li Zhi suffocate hard in literature.

Then seize this point and directly drive Li Zhi out of the court.

They firmly believed that at such a young age, it would be impossible for Li Zhi to achieve anything in literature.

Otherwise, he would not just be a demon, but a god directly.

As a result, a trend of public opinion on whether Li Zhi devoted all his energy to the left side of the door because he was not good at literature spread among the majority of literati.

And the purpose of the people who organized this public opinion was to force Li Zhi to participate in a literary event in the near future.

Li Zhi didn't pay any attention to all this.

He is now busy promoting honeycomb stoves and honeycomb coal.

With the onset of winter, households in the resettlement sites have begun to install honeycomb stoves.

Everyone assembled the honeycomb stove according to the method taught by Li Zhi and tried to use it.

Li Zhi himself came to a house, and he instructed the man of the house to light a piece of honeycomb coal and put it in the hearth.

The heat emitted by a piece of coal was not large, and Li Zhi tried to boil a pot of water, which took nearly an hour to boil.

However, by this time, the first piece of coal had begun to burn completely, and Li Zhi immediately asked the man to add a second piece of honeycomb coal.

Soon the heat emitted by the stove began to rise, and Li Zhi immediately asked him to boil a second pot of water.

This time it didn't even take half an hour, and by the time the pot of water had completely boiled, the second piece of coal had only burned a small half.

At this time, the temperature in the room has begun to increase significantly through the heat dissipation of the stove and chimney.

Everyone also moved away from the stove in search of a cooler place.

It was another half hour or so, and Li Zhi asked for the last piece of honeycomb coal.

So far, only a small flame has been left of the first coal.

Li Zhi silently calculated, and asked Li Zhe: "A piece of coal can burn for an hour and a half, which is not bad compared to charcoal, right?" ”

Li Zhe said: "Your Highness said that although the two are about the same, the price of coal is only 20% of charcoal, and the use of coal is completely incomparable with charcoal." ”

Li Zhe's analysis is very pertinent, at present, the high-grade charcoal is about 20 wen per catty, and the medium charcoal is also 10 wen.

However, the calorific value of honeycomb coal is about the same as that of high-quality charcoal, and the selling price is only five cents a piece.

In addition, honeycomb coal can be directly used to boil water for cooking, so there is no need to worry about the waste of heat.

Charcoal is absolutely not able to do that.

The only difficulty at the moment is the promotion of stoves.

Because at present, Datang's pig iron production has just increased.

The price that can be sold to the people is relatively expensive, about ten wen per catty.

And a honeycomb stove uses about ten catties of pig iron.

Combined with other costs, each stove will sell for 200 yuan.

The price of the chimney is not cheap, so in order to ensure lightness, the chimney uses wrought iron.

Although the process has been improved, the price of wrought iron is still about twice that of pig iron.

And each chimney must weigh two catties, and each household must use at least three or four knots.

Coupled with the elbow and other connectors, each set of chimneys also has to start from ten pounds.

In this way, the chimney will cost nearly 300 wen.

Each set of stoves costs 500 yuan, which ordinary people can never afford.

So Li Zhi thought of the way to pay in installments after a little thought.

He set the installment time as five years, and he only needed to pay 100 wen a year to easily use the honeycomb stove.

In addition to this, he also gave preferential treatment on the sale of honeycomb coal.

That's to buy 100 more and get 10 free.

In this way, most ordinary people can afford to spend it.

The problem of sales volume can be solved smoothly.

These are just commodities to be sold to ordinary people, and Li Zhi's main focus is small profits but quick turnover.

With a sales strategy, Li Zhi immediately asked Pei Mingli to organize people to sell in the market.

At the same time, he also asked Pei Mingli to contact agents in large numbers.

With the help of these people, he wants to sell the honeycomb stoves all over the country.

At the same time, he arranged for the manufacture of boilers and heaters.

These things are going to be faced by the rich and rich.

Therefore, the price of each set was set by him to start at 5,000 yuan.

As soon as this thing came out, it immediately attracted Li Shimin's attention.

He has long wanted to intervene in Li Zhi's career, but he has always been embarrassed to mention it to Li Zhi.

Now seeing such a lucrative project, Li Shimin can no longer care about his face, and directly calls Li Zhi to the Taiji Palace.

He said to Li Zhi in a gentle tone that he had never felt before: "Pheasant slave! Seeing that you have invested in so many industries, my father thinks that you don't have much money left in your hand, right? The father still has some in his hand, why don't you let the father participate in it? ”

As soon as Li Zhi heard this, he knew that he was envious of making money.

Thinking about it, as the lord of a country, he is stunned to let his harem be frugal, and this emperor is indeed poor enough.

Li Zhi will not give up this big thick leg sent to the door.

So he immediately patted his little chest and said without hesitation: "What is the father talking about?" Since the father took a fancy to the property of the son, the son gave half of the shares to the father, how could he let the father break the bank? ”

Li Shimin waved his hand and said: "No, it's not easy for you to do business, how can my father take advantage of you in vain." ”
