Tin cans are not afraid of light, have a long storage time, and are more convenient to transport than glass cans. The disadvantage is that it is expensive and easy to rust when wet.

As long as you pay attention to the rain and water during transportation or storage, the latter defect can be avoided, and the main thing is the cost.

When she was a peasant girl, there was no mine at home, so the first thing that came to mind was glass cans.

But at this moment, the Jinnan Wangfu behind her has a whole mine, and with the current iron ore reserves, there is no pressure to make iron cans in a few tons.

Such a simple question actually bothered her for months.

In this way, Qinbei, which is hilly in the hilly area, can get rid of poverty and become well-off by planting lychees.

She talked briefly to Yan Kejin, originally wanting him to come forward and contract several barren mountains in a radius and hire local villagers to grow lychees.

Unexpectedly, he bought it directly, and in an instant, a radius of hundreds of miles became the territory of the palace.

This master buys land and mountains at every turn, and Xu Yin is no longer able to complain.

Thinking about it, after the canned food project is completed, it shouldn't make him lose.

However, since you want to make canned food, it is better to have a richer variety, just a canned lychee, which will be monotonous after a long time.

She dragged Yan Kejin into the mountain to investigate.

After looking at it, I felt that the soil here is not only suitable for growing lychees, but also for growing tropical and subtropical fruits such as longan, oranges, and pineapples, and these fruits are also quite suitable for canning.

"Pineapple? What is it? ”

Xu Yin saw that he didn't know, so he drew the several tropical fruits mentioned with charcoal, and turned around to let people look for fruit saplings to have a reference.

Yan Kejin looked at the pineapple picture for a long time.

Xu Yin: "......"

Well, there are no pineapples in Lingnan at this time.

"Why don't you send someone to look for it on the other side of the continent? This kind of fruit tree prefers hot and humid environments, and there may be one over there. ”

"Hmm."

Yan Kejin took the picture she had drawn, ordered a guard and hurried to the outer continent of Vietnam.

However, I have to take a ferry to the outer continent of Vietnam, and I am afraid that it will take a month to come back even if there is no delay on the way.

Xu Yin told the guards that if there were these fruits she painted on the other side of the outer continent, there was no need to come back to return to them, and they would directly find a batch of high-quality fruit tree saplings and pull them back with a horse-drawn cart.

There are local mountain farmers who know more about planting than her, and all she can do is teach them the new method of manure.

When you're done with that, it's time to go back.

Don't want to explore the entire county at once.

At this rate, it would be good to be able to explore Baigui County within three years.

[Ding-Nanban's Baigui County has explored a quarter]

[Ding - Expand the outer continent to explore, activate a new map, and reward 2000 energy points]

Unexpectedly, on this day, the system sent two mission messages in a row, which made Xu Yin quite puzzled.

A quarter of the way to explore Baigui County? Didn't you?

Outside Vietnam has started to explore? But she didn't go to Vietnam, not even Qinxian.

What's going on? The system pumped?

Xu Yin was puzzled until Yan Kejin received a letter from the flying pigeon, telling her that Yan Jiu had bought the entire mountain forest where the rubber forest was located.

In the outer forests, rubber trees can be planted and rubber plantations can be built at any time.

There are many precious old trees in the deep forest that are hundreds or thousands of years old, which will not be moved for the time being, and will be kept for the marriage of children in the future.

Of course, if she likes it, cut down a few and let Yan Jiu bring them back.

There is also a flying pigeon from another guard, who has crossed the sea to the outer continent of Vietnam, and the fruits drawn by Xu Yin are indeed available in the outer continent of Vietnam, but the pineapple is wild.

According to the guards, the people there were insensitive to the pineapple, saying that it was poisonous, and that their mouths were numb, red and swollen after eating it.

Unless the hungry really have nothing to eat, most people don't want to touch it.

So I specially wrote to report: Do you want to bring it back to Qinbei?

Absolutely!

"There's something special about eating pineapple, but that's not a problem. You ask him to buy fruit seedlings, and if it's convenient, hire a few locals who are good at growing these kinds of fruit trees to go back to Qinbei and teach them how to plant them. ”

In this way, the progress of the task that suddenly appeared in the system made Xu Yin roughly clear: the exploration may not have to be carried out by her in person, and the people she sent are also counted.

As soon as the mind is opened, the mood is not to mention how happy.

"What good things have happened to the princess?"

Yan Kejin wrote a handwritten message, released the flying pigeon, and when she came back, she smiled at the corner of her mouth, and sometimes hummed a little song, and couldn't help but smile and ask.

"I won't tell you!" Xu Yin smiled playfully.

Yan Ke Jin stepped back and stepped forward to hug her: "Let this king guess, yes...... Pregnant? ”

As she spoke, her warm big hand, with his unique crisp aura, caressed her lower abdomen.

Xu Yin was stunned for a moment, and then smiled: "You think too much." ”

Yan Kejin just guessed, and when she refuted, she was not disappointed.

The accompanying imperial doctor called the princess to take the pulse, saying that she was in good shape.

There will always be heirs. It's okay if you don't come now, and you can enjoy the joy of Dunlun with her a few more times.

Thinking like this, my heart is a little moved.

Looking down, I saw that the person in my arms had an apricot face and peach cheeks, and her face was charming, and she didn't let the maid come in to hold the lamp, so I hugged her to the bed in the dark......

When I returned to Fucheng, it was already August when the cinnamon was fragrant.

The housekeeper led his subordinates to hang lanterns on the corridors and eaves of the house.

At night, candles were lit, and the faint red light illuminated the nine-song corridor in the house.

The kitchen also asked the carpenter workshop to make a batch of brand-new mooncake molds, large and small sets with dozens of patterns, to prepare for the autumn harvest festival.

Xu Yin's salty zongzi is very popular in the house, no, seeing the prince and the princess returning home, the imperial chef hurriedly came over to ask the princess what kind of salty mooncakes she likes to eat, and the kitchen prepared the fillings in advance.

When Yan Kejin heard this, she also looked at her expectantly.

Xu Yin: "......"

Salty mooncakes?

I haven't really studied this.

"Why don't you try the golden sand custard stuffing and the salted egg yolk ham filling? These two salty flavors should be okay. ”

The popular moon cakes in Yanhua here are similar to Cantonese style, but they are a little hard when cold, and they are not as soft as the Cantonese moon cakes of later generations.

Xu Yin estimated that the syrup was too thin and needed to add too much flour to adjust the softness and hardness of the dough, resulting in slow oil return after cooling or no oil return at all, so it tasted hard and the taste was not good.

Fortunately, there is no shortage of sugar in the house this year, Xu Yin asked the little girl to move the previously boiled sugar to the big kitchen for the cooks to make moon cakes.

In addition, she plans to bake a batch of Suzhou-style pickled vegetables and red bean paste mooncakes.

Then make the lychees brought back from Qinbei into canned lychees in sugar water, and give them to the prince as a Mid-Autumn Festival gift.

She asked people to build a baking kiln in the back garden of Xu's mansion.

The drawings of the baking kiln are asked to be redeemed by the system, which is much more elaborate than she thinks, and the lower open flame can be used for barbecue; The upper layer can be used to bake mooncakes and other snacks.

When the baking kiln is built, the Mid-Autumn Festival is also in sight.

Xu Yin led the grandmothers and maids and began to make Suzhou-style mooncakes.
