However, with the skill book and scenario simulation function, she felt that it shouldn't be too difficult to tinker with a generator.

She combed through the materials she had and found that the only material she could replace was silicon, which is indispensable for making solar panels.

Fortunately, the energy point is still relatively rich, so I simply bought a batch of solar panels in the system mall and started to tinker with solar motors.

Seeing that the princess was busy, no one reminded her to go home, and it was the turn of King Jinnan to be sour.

But the princess is right, cement and magnetite are new things, she made them out and threw them at him, if he also walked away and left it alone, no one at the bottom understood.

While the princess was busy, she quickly promoted a few henchmen, and after cultivating them, let them lead their teams to pave cement roads and open iron mines, so that they would bother him less in the future.

Inevitably, the princess was too busy to think of him, so King Jinnan gave her gifts and brushed up on her sense of existence.

Sometimes it's a piece of fine jade seed, sometimes it's a box of saltwater pearls.

Xu Yin is busy, how can he have time to think about it, just think that the people below will honor him.

When I saw the pearls, I couldn't help but think of the Maritime Silk Road, and asked with great interest: "Is there any trade between merchant ships and the South Seas?" ”

Originally, there was no, but her mention of it gave Yan Kejin an idea.

That's right! Beidi can trade, but what about Nanyang?

"However, Viet Nam is a place of exile, and the conditions are more difficult than those of the Southern Barbarians, and further south, there are small countries, does the princess think it will be rich?" He frowned.

"Suppose we can trade with Beidi here, what do you think?" Xu Yin asked him rhetorically.

Beidi and Nanban are not as rich as the Central Plains.

However, Beidi is dominated by nomadic people, with herds of cattle and sheep, and the most important thing is meat, followed by dairy products, and cotton also grows very well.

Nanban is poor, but it also has its own special products, such as tea, pearls, and Shoushan stone.

With Xu Yin's contribution to the manure method, rice will not be barren if it is planted for three seasons a year. If the two places can trade, it will only make each other's lives better.

Seeing that he was thoughtful, Xu Yin continued: "It's just trade, and I don't want it to be rich or not. If you are not rich, you can change more things and come back. ”

Xu Yin drew a blueprint for him.

As a result, as soon as the man straightened out his thinking, he wanted to form a fleet to go to sea and trade in minutes, as if he would make a lot less money if he was slow down.

Xu Yin stopped him with a smile: "You forgot what I said earlier?" The current ship is too risky to go to sea, so you can't be prepared to sacrifice every time you go to sea, right? Since we want to go to the ocean, we must first build a ship suitable for the ocean, and sharpen the knife without mistakenly chopping firewood. ”

In addition to the ship itself having to withstand the wind and waves, the ship must also be equipped with some self-defense equipment, in case of pirates? Can't you beat it, isn't it still for nothing?

With a large reserve of iron ore in hand, cold weapons are not worried.

But if you go to the ocean, cold weapons alone may not have a deterrent effect.

If only you could find saltpeter mines, ask the system to get an upgraded gunpowder recipe and make the simplest musket and cannon.

If people don't offend me, I won't offend anyone, and if people offend me, I must at least have the means to fight back.

Just when Xu Yin's mind was turning "where to get saltpeter", the ventilation system "ding" the task of [Exploring the Land of the Southern Barbarians] again.

Xu Yin: "......"

Could it be that the system-rewarded map really marks the deposit?

Then she must complete this task!

"Lord Wang, where is the cement road paved?"

Yan Kejin saw that she finally remembered the trip, smiled, and marked the cement-hardened section of the road on the map:

"The cement road out of the city has been paved to Longcheng, but it takes ten days and half a month to maintain it depending on the weather conditions, so the passable road section is currently in Yongfu County."

Even so, Xu Yin was quite surprised: "It's all paved to Dragon City?" That's fast! ”

"The three teams are divided into three days and nights to rush to work, and every place they go, they will also hire some local strong laborers, and the speed of the more people will naturally be faster."

After a pause, Yan Kejin added with a smile: "Don't worry, it's not a forced labor, it's a payment of money." ”

Xu Yin believed what he said.

After this time of getting along, she saw the kind side of his cold skin.

"At this rate, we can leave for Yong County by this time next month."

At that time, the main road from Fucheng to Yongxian County can be said to be unimpeded, and the carriage will no longer be dusty.

In a happy mood, Xu Yin's rhythm of immersing herself in the motor is also much brighter.

Until Uncle Wang sent someone to say that the crops in the experimental field were partially ripe, and asked her if she wanted to go and see it.

After getting married, the palace and the Xu mansion ran at both ends, except for the test field, she would ask at the beginning, and then it was basically handed over to the grandmother to send people to take care of.

"Of course I want to check it out."

In the fifth month of the lunar calendar, the rape flowers in the fields bloom and bloom, and now they are full of rapeseed.

The corn is ripe.

Although each plant still bears only one corn stick, the corn stick is about twice the size of the original one, and the corn grains are golden and full, and the yield is definitely higher than in previous years.

Seeing Uncle Wang and the others grinning at the corners of their mouths and ears, Xu Yin was also sincerely happy.

Her five-acre experimental plot is the best growing of all the fertile fields.

Uncle Wang kept muttering at first.

Although he is just a tenant farmer in the palace, the master can do whatever he wants, so he can talk too much.

But in the end, it is five acres of fertile land, yes, after the palace planted the crops, he came to see it every day without worry, even if there were people in the field who were responsible for weeding and fertilizing, and he didn't need to be busy, he couldn't help it.

This is a look at the unusual:

The crops planted by the princess are the same every day, and they grow like the wind.

Especially for rice, before the harvest season, the ears of rice sink and bend the ears. And when I got closer, the rice seeds per acre of field were not the same.

Let's take a closer look, obediently! Six varieties were planted in the three acres of rice fields, some slender and long, and some green and green.

No wonder! How could the princess be willing to go to the field to farm, not for food, but to plant flowers for the sake of good looks!

Look at the two acres of land next to the rice field, one of which is planted with mulberry trees.

The mulberries have been ripening since last month, and they are picked and sent to the palace, where they are said to be used by the imperial chef to make jams and snacks, and they taste very good.

Each household in the Zhuangzi was given half a catty to give the children in the family a tooth sacrifice, but the children were happy, and after eating enough, they encouraged their parents to plant mulberry trees in front of and behind their houses.

When the princess heard about it, she encouraged everyone to plant mulberry trees, and the mulberry leaves were collected at the market price.

The silkworm babies who feed on mulberry leaves can be comfortable during this time, buried in the pile of fresh mulberry leaves, eating all the time, and eating themselves to be snow-white and fat.

The first silkworms began to form cocoons, and the people of the palace said that these would be spun into silk to make clothes in the future.

Silk brocade clothes are precious, and the tenant farmers who work in silkworm houses dare not be careless about it.

Fortunately, there is a silkworm raising manual drawn by the princess, as long as you raise silkworms according to the atlas, there is generally nothing wrong.
