Ever since the discovery of hematite, he has been using coal that he brought from the Northlands to make iron.

But the quantity of this thing is limited, and seeing that the reserves are about to bottom out, if you continue, you can only ask the people to buy firewood.

But the firewood is too useless, no matter how much you buy, you can't burn a few furnaces, and the temperature can't reach the smelting of weapons.

I was worried about this, and I brought back such good news!

"Reward! Rewards! ”

"Thank you, Lord Wang!"

After appreciating her subordinates, Yan Kejin turned her head to meet Xu Yin's smiling eyes, and her gaze softened: "It's still the princess who thinks thoughtfully." ”

Xu Yin: "......"

This credit is a bit of a vain.

She was purely trying to complete the task of the system, and she wanted to find the coal mine crookedly.

However, it can be seen from this that the natural resources of Nanban are indeed quite abundant, but the people do not understand them and the officials do not do their best, resulting in them being like dust pearls and covering the ground for many years.

There is a good start in the coal mountain, and there is no need for Xu Yin to remind her, Yan Kejin is more motivated than her, and wants to continue to send people to various places for carpet inspections.

Xu Yin stopped him with a smile and a smile: "The New Year is going to be celebrated in less than a month, and if you send them out at this time, wouldn't you want them to stay in a foreign country for the New Year?" How lonely! ”

Only then did he dispel the idea of immediately sending people to explore other counties.

After that, as the guards who went to the west of the county, the north of the county, the southeast of the county and other places to investigate returned with more or less harvests, Xu Yin finally heard the system's dingle about the completion of the task of [Exploring Baigui County].

Get a map of Baigui County produced by the system, detailed to the aquatic products rich in each tributary, and the minerals covered by each mountain.

I really have a sense of control of "a picture in hand, I have the world".

Not to mention anything else, just mineral resources, energy mines, metal mines, non-metallic minerals, large and small, add up to hundreds.

It's just that some mineral reserves are small, and the current development technology is not advanced enough, and if the development is not sufficient, it will be wasted. But there are also some mineral deposits that are staggering.

For example, manganese ore, rare earths, and gypsum in the south of the county.

Silver mines, copper mines, granite, and marble in the eastern part of the county.

Iron ore, limestone, and kaolin in the county.

Aluminum, gold, and coal mines in the west of the county.

Silver, tin, and lead mines in the north of the county.

Gold, silver, copper and iron - the four kings of the metal world live together!

All kinds of metallurgical auxiliary materials and building materials are also available.

Sitting on thousands of mines, who is still rare to have the title of a prince?

Xu Yin couldn't help but complain in her heart.

After all, the current emperor has not yet reached the age of abdication in his seventies and eighties, and he has tasted the sweetness of power. In this way, I don't know how long it will take to wait for the crown prince to ascend the throne.

It is better to make your own fortune, refine your own weapons, and build your own powerful kingdom in a fiefdom in a corner of safety.

Speaking of weapons, Xu Yin couldn't help but think of saltpeter, which can make both ice and gunpowder.

Hurriedly looked for it carefully on the map.

Pregnant!

In the mountains at the junction of Baigui and Baipu counties.

The reserves are not large, compared to the rich reserves of coal, iron ore, kaolin and other minerals that stretch for hundreds of miles, this small saltpeter mine is not at all inconspicuous.

But fortunately, the use of saltpeter ore is not as extensive as iron ore, not to mention that even if the demand increases greatly in the future, there are not other counties.

She didn't believe that there was only this small saltpeter mine in the entire Nanban.

Xu Yin used the old-fashioned skills exchanged with the system in the small world in the 80s to make the Baigui County map into a parchment scroll with a history of several hundred years.

Of course, before that, those small reserves that do not have advanced technology and are not suitable for current development have been erased, and only one or two energy mines such as oil and natural gas have been left.

Rao is like this, and the content of this parchment scroll is enough to shock Yan Kejin.

"Where did the princess get this treasure map?"

“……”

Xu Yin thought about his reaction, but he didn't expect that he would characterize the map as a treasure map.

But if you think about it, it's right! What is the difference between a map with various types of large mines and a treasure map?

A gold mine is equivalent to countless treasures.

What's more, there is more than one gold and silver mine marked on it.

"No matter where you get it, give it to the prince at this moment! I hope that the prince will make good use of it. ”

Let's go big and develop it!

Strive to build Nanban into a safe city that cannot be attacked by foreign enemies in the shortest possible time!

I don't have the money to open a gold mine, a silver mine or something.

When the money is abundant, they will build ships, make artillery, and train troops.

The cement road is paved to all parts of the Nanban, and the high-yield grain is all over the corner of the Nanban, and the big ships that are not afraid of wind and waves and pirates can go to the ends of the earth.

Food, clothing, housing and transportation, no need for court relief, no need to rely on people's snorts, and even more well-fed, warmer-clothed, and better than the people of the Central Plains!

Go ahead!

With your ideals and ambitions, let's create a prosperous paradise and prosperity.

Xu Yin thought a lot.

gave the sheepskin scroll to Yan Kejin, and she didn't ask anymore, mining these things are really not what she is good at.

And she is also very busy: making soy sauce, making tofu, and building a textile workshop.

It is also planned to improve the original spinning and loom into a water spinning machine and a loom on the basis of the original spinning machine.

In addition, the sugar mill will soon be put into operation.

As the year draws to a close, the sugarcane is finally ripe.

In addition to Wangfu Zhuangzi, Chenjiazhuang at the foot of the strange mountain also brought tons of green-skinned sugarcane.

On the day the sugar mill opened, Yan Kejin came with Xu Yin.

The guys in the workshop, in addition to the subordinates of the palace who pinched the deed of sale, there are also many civilians who came out to look for short-term jobs in winter.

Short-term workers are responsible for transporting sugarcane, extracting sugarcane, and processing bagasse.

The work of boiling sugar, decolorization, sugar making and other technical content is pinched in their own hands.

This is the first Nanban special product to enter the Central Plains, and it can't be overstated.

The wooden giant juicer has been assembled, and the first batch of sugar cane is brought to the workshop, where the head and tail are removed, washed, peeled, cut into small pieces, and placed in the juicer's large vessels.

The solar motor runs up, making a buzzing motor sound, and the sugarcane section enters the mixing barrel, and the sharp iron blade is like mud, stirring the sugarcane naturally.

Soon, the sugar cane juice pooled into the wooden sink below and flowed down the slope into a large iron pot.

When it is full of seven or eight minutes, put down the plug board and cut off the juice, and the juice continues to flow forward to the second large iron pot...... And so on.

The workers have an orderly division of labor, some are responsible for burning the fire and controlling the temperature, and some are responsible for stirring.

The stirred syrup, if it is brown sugar, is transferred to the brown sugar pressing mold workshop for cooling, and the cooled sugar cubes are crushed and ground into brown sugar powder, and the mold is molded into beautiful small pieces of brown sugar.

If it is made of white sugar, it is transferred to the sugar workshop at the step of syrup, and after decolorization with activated carbon, the white sugar that is as clear as snow is precipitated at high temperature.

The first batch of sugar was produced, but the workers in the workshop were so excited.

Sugar!

Sugar, which is classified as a luxury like soy sauce, is actually from their hands!

Before applying for a job at the sugar mill, I never thought that the sugar mill was actually a sugar maker, and I thought that it was made of honey, caramel and other sugar cubes to make snacks and candies.

Xu Yin tasted the freshly baked brown sugar and white sugar, and nodded approvingly: "Not bad!" It seems that they have mastered it, and the Fucheng Sugar Mill will be handed over to the two of you in the future. ”

Qiushuang and Cailian glanced at each other happily and nodded vigorously: "I will definitely live up to the princess's trust!" ”
