Some strange thoughts came to her heart, but they only ignited two or three small flames slightly, and they were suddenly blown out by the cold wind.

The weather in the north is not as good as that of Jinmancheng, the sky is gloomy and cold, and it is estimated that there will be seven or eight days before heavy snowfall.

When Fang had just run all the way, Yao Yun had already written down the route and terrain in detail.

She loosened her stiff neck and wrists, took out her pencil and ink cartridge again, and deliberately marked the location and approximate area of each water source mentioned by the farmer.

She ordered Xue Huai and Fourteen to use bamboo tubes to dig up soil from different water sources and mark the soil characteristics of different water sources. Depending on the fineness and humidity of the soil in different parts of the water source, the crops that can be grown will vary. It is the best policy to pursue advantages and avoid disadvantages, adapt measures to local conditions, and minimize the waste of manpower and material resources.

Crops like quinoa and sorghum are of high quality and inexpensive, and it is probably not a problem to grow them in such arid wasteland. However, due to the endless wars in the past, this place is sparsely populated and the roads are remote, and the people in the city are reluctant to drag their families to settle down here. Now with the additional subsidy, it shouldn't be a problem.

Yao Yun was still thinking hard about how to grow more expensive and valuable crops in this barren wasteland, if he could get twice the result with half the effort, it would be excellent.

"Liu Gong, what do you think of planting peppercorns in this large area of soil?"

Lao Liu, who has lived in the north for a long time, was born in a family of farmers for generations, and has a lot of insights into the affairs of farmland.

"Yao Niangzi, the villain has heard that the pepper tree is cold and drought tolerant before, and it can indeed be considered. However, the pepper seeds are precious, and the pepper is a precious tribute sent to Chang'an, the villain has not, has not seen what the pepper seeds look like, and our locals have not tried to plant the experience here. The villain can't give you a word. ”

"It's okay, at the beginning of spring next year, I'll come here to try it myself, and I don't know if I can succeed. Although pepper is a precious thing, if it can be planted smoothly, flowering and fruiting, greatly increasing the yield, it will definitely be able to sell at a good price. And this precious spice may still be able to fall into the homes of ordinary people. ”

The group continued to walk to the next place, and the books in Yao Yun's hands were already densely packed with several pages.

"Yao Niangzi, although the water sources in these places are scarce, some medicinal herbs can also survive and grow in such an arid and water-scarce environment. However, the villains, these poor peasants, can't get the seeds of these precious medicinal materials. If you have the support of the Beiting Metropolitan Protectorate, you may be able to achieve results. For example......

Yao Yun smiled, turned the book to a new page, and continued to bury his head in writing down a few medicinal materials that Liu Gong said were suitable for planting.

Astragalus, Skullcap, Licorice, Mao Zhimu, Parsnip, Shayuanzi, Salvia, Codonopsis. When she was doing her homework before, several of these herbs were also recorded in the booklet.

In this dry and rainless northern land, medicinal herbs are the most suitable for harvesting and preservation. If the profits go up, it can also greatly alleviate the pressure on medicinal materials in the northwest region and benefit the local people, which is actually a good thing to kill two birds with one stone.

The sky was getting dark, the sky was dark, and the wind was cold.

The group decided to settle down at a small inn in the northwest of the Northland, and return to the city at dawn tomorrow.

After a brief dinner, Xue Huai quickly brought a brazier for everyone to roast. Fourteen, as always, stood guard outside the door.

Yao Yun had just eaten half a naan cake and drank a few mouthfuls of hot mutton soup, and now he was roasting a fire in the house, and his body finally warmed up, and soon his sleepiness gradually rose.

Knock-knock-knock.

It was an extremely subtle and rapid tapping sound, as if someone was desperately slapping a wooden board or something.

Yao Yun has always been a light sleeper, and he woke up suddenly for some reason.

Bai Lu, who was sleeping on the side of the couch, rubbed her eyes in a daze, and said softly: "Lady, are you having nightmares again?" Slave go pour you a glass......"

Yao Yun grabbed her sleeve and asked in a suppressed voice, "Bai Lu, did you hear anything, what knock sound?" ”

Bai Lu listened patiently for a while, except for the neighing of fierce beasts and wild insects from time to time, there was no other sound, and she shook her head inexplicably.

"Forget it, maybe I'm stunned. Go to sleep. ”

Yao Yun lay back on the bed and listened carefully, but unfortunately the strange voice never sounded again.

The sky is slightly spit fish white, and the morning glow shines brightly, as if someone has skillfully knocked over half a jar of Dan pigment, and the blue and white edges are fascinated and appropriate.

"Xue Huai, Fourteen, you can bring a few more pieces of naan, we won't rest halfway later, it's better to rush back to the city as soon as possible."

Yao Yun softly told them and helped them fill an extra bowl of hot rice cereal.

"Go, go, don't grind ......"

"If you haven't eaten enough, take two steps faster......"

The man's rude and loud urging came from his back, and everyone couldn't help but turn their heads sideways to look.

Three or four coarse linen country grooms surrounded the dozen or so beautiful ladies in the middle, baring their teeth and grinning, and the whips in their hands waved wildly at their white arms and thin backs without pity, as if they were frivolously teasing the foals under their mounts.

The ladies in the middle are all hanging their heads and supporting each other, their clothes are ragged and their faces are haggard, but it is a pity that even such messy and dirty cannot hide their fair and translucent skin and slender waists. The blonde hair was stained with a lot of dirt, but it was still beautiful.

They are a group of Hu women!

In this era, orchids with high foreheads, deep eyes, eagle noses, plump and beautiful appearances were extremely sought-after and expensive slave goods. These slave girls were three to five times more profitable than silk and were one of the important commodities of the Silk Road trade. Slave trafficking was not easy to obtain.

Yao Yun couldn't help but glance at the lady a few more times, and suddenly her expression was overwhelming.

Although one of the ladies was also blonde, fair-skinned, and wearing a shabby bearded skirt, Yao Yun could see the oddity at a glance.

Her eyes are the black pine eyes of ordinary Han people, although her face is covered by heavy makeup, but her cheek bones are long and flat, but they are bright Han outlines, and this lady's eyes seem to have some déjà vu.

Yao Yun took a sip of hot soup, replaced his face with a gentle and flattering smile, and pulled the handkerchief to stop these rough grooms.

"Hello uncles!"

Several rough horsemen were stunned for a moment, staring at her with wary eyes.

An elderly groom in the lead stroked his beard and said in a cold voice: "Hmm, the little lady doesn't know what to do, what do you mean?" ”
