An ordinary sheepskin jacket, one without embroidery, and the other without precious stones, was actually exchanged for two catties of fine sugar as white as snow!

Two sticks of cistanche were exchanged for two bottles of hoisin sauce and a handful of stewed soup called kelp, which is very delicious!

It can make a few spies happy.

How can you care about spying on the military, take out everything you have on hand and exchange it for sugar, soy sauce, and seafood...... Then he hurriedly slipped back to the gate to report.

Such a thing in exchange for so many condiments, and seafood that is not common outside, what kind of city and what kind of battle to fight! Wouldn't it be nice to get something in exchange? There are no casualties yet.

When the Tatar king heard the spies' report, his first reaction was disbelief.

These things, the spies who sneaked into Beijing last year also said that they had seen them, but the prices in Beijing were not so low, only the princes and nobles could afford to eat them, how could Yanguan sell them so cheaply?

Keep exploring!

A second wave of spies sneaked in again.

This time, they brought a lot of leather jackets and wild medicinal materials that were not worth much in their eyes.

Wang said, if you can't spy on the military, it's better to change some oil, salt, sauce, vinegar, and canned fruits that are scarce outside the customs.

The spies mingled in the ranks of the people of Yanguan, coaxing them to exchange for a bunch of things.

Once again, it is verified: these snowflake white sugar, ruby brown sugar, and canned fruits, which are sold at sky-high prices in Beijing, are indeed very cheap in Yanguan.

The Tatar king came in interest.

"Find a way to keep mixing in and changing! This king wants to see how many such good things there are in Yanguan! ”

At the same time, after the Mid-Autumn Festival, the Jinnan Wang convoy that set off immediately, in addition to hurrying, also purchased a batch of farmland Zhuangzi along the way as a spare granary, so that when they arrived at Yanguan, it was already the spring of March when the ice and snow gradually melted, and the New Year was spent on the road.

Mama Feng, who arrived first with the dart car, had already taken the maids to get up and down the mansion and clean it up like a new house.

Originally, Xu Yinnian was old, and when she passed by Furong County, it was Mama Feng who insisted on coming to Yanguan who wanted her to go back to Xu's Mansion to reunite with her family.

"The old slave is old, but his hands and feet are still nimble. After Yanguan settles down, it is time for the princess to have a child, the old slave is not proficient, but when it comes to taking children, the old slave is still a little sure. Besides, it's not safe to hand it over to other people's old slaves, Chunlan is a few, and she is still a child. ”

Xu Yin was speechless.

If Mama Feng didn't mention it, she didn't think about the child at all.

In fact, the past two years have been too fulfilling, and there is almost no time to think about pregnancy and children.

That night, she asked Yan Kejin anxiously, she had been married for two years, why didn't she see him give birth? Doesn't he want a child of his own?

The dog man smiled meaningfully: "This king asked the imperial doctor, the princess seems to be weak and weak, but her body is still strong, and she is not pregnant because her fate with the child has not arrived, so there is no need to worry." ”

“……”

Who's in a hurry!

Yan Kejin lay on her shoulder socket, and the hot breath she exhaled sprayed directly on the tips of her ears:

"Does the princess also want to say that it is good not to have children to disturb? Is the 'world of two' that the princess is talking about like this? ”

"......" You think too much.

She was wrong!

She shouldn't have stirred up the topic.

After provoking...... Anyway, from the topic of "children", I jumped to the unspeakable "battlefield".

When she woke up the next day, Xu Yin felt like she had been run over by a big truck all night, and her body was sour.

It was the dog man, with a refreshed face, who accompanied the princess to breakfast and went to the barracks.

When I first arrived, I had a lot to do. The most important firearms battalion should be settled as soon as possible so that regular training can begin.

Xu Yin went back to the room to make up for sleep, and woke up again, it was already noon.

Mama came in and said that the lady of the Captain's family came to visit her and asked her if she wanted to see her.

"See you."

Just learn about the current situation of life in Yanguan.

There are ten captains under Yan Kejin's management, but there are only four female dependents who came this time.

The other six captains were either not married, or left their wives at home to serve their in-laws, and did not accompany the army.

Fortunately, the daughters of these four people have been in the army for many years, and they know Yan Guan well, but Xu Yin can answer a few words when she asks, which is enough for her to understand.

"Madame doesn't know that there are very few fields in Yanguan that can produce grain, most of them are sandy loam, and everything is sparsely planted, and the grain has to be transported from the inner county. Sometimes the shipment comes late, and the days of three meals and no clear soup and water are really tormenting. ”

"Madame would be frightened if she saw the house where the locals lived. Many of them don't build houses, they just find a hill to dig a stone cave, and they say that it is warm in winter and cool in summer. Most of the houses in Yanguan City are either military dependents like us, or the inner county comes here to do business. ”

"Madam, the concubine has followed her husband to Yanguan, and the most unaccustomed thing is that water is too scarce. There is little rain here, and the local people have experienced the drought of previous years, and they have palpitations, even if it is not the dry season, it is very economical to use water. ”

Before Xu Yin came, she was fully mentally prepared for the scarce materials in Yanguan, but she didn't expect the reality to be even more difficult than she expected. Especially water, which can't be transported from Nanban or Zhuangzi along the way!

She desperately recalled, how did the future generations solve the problem of water use in the northwest?

South-to-North Water Diversion?

Long-term planning is okay, but to alleviate the immediate predicament, far water can't quench the thirst of the near.

After all, with the economic strength and scientific and technological level of later generations, it took more than ten years and hundreds of billions of dollars to realize the water supply.

[Ding - Explore the northwest region of Yanhua and complete a reward for the region's map.] 】

At this time, the system issued a task to her again.

Exploring Yanhua Northwest China?

This is much more than Nanban, a large expanse of the world, the difficulty of the task is not small, but fortunately, the corresponding energy point rewards are also a lot after completion.

After Xu Yin sent away several female dependents, she began to arrange for people to investigate.

Unexpectedly, during this investigation, I accidentally found a group of Tartars dressed in disguise and infiltrated the pass.

At first, Xu Yin also thought it was a meticulous work, but she didn't expect that the interrogation revealed a ridiculous truth.

"What? Are they here to trade? ”

"Hmm."

Yan Kejin was also a little crying and laughing, leaning on the back of the chair and twisting his sore eyebrows, he personally interrogated all night, but he didn't want such an answer.

It stands to reason that entering the customs is to be civilized, and the generals guarding the customs have neglected their duties and have been dealt with by him, most of them are Yan Keheng's people. He took this opportunity to rectify the appearance and discipline of the army.

“…… At first, he refused to say whether he was alive or dead, but then a pregnant woman waiting for brown sugar at home couldn't help crying, so he recruited them. In addition, this time, two groups of people have disguised themselves as ordinary people in the customs and mixed into the bazaar, and exchanged sheepskin jackets, wool felt, ghee and other items for sugar, soy sauce, canned food, and muslin cloth that were scarce outside the customs ......."

Xu Yin's eyes lit up as she listened:

"Lord Wang, I know how to stop fighting!"
