The people on the city wall received the gold medal and identification documents and quickly verified the identity of the visitors.

After confirming everything was correct, the city gate opened a passage large enough for one person to pass through, the token and identity documents were returned, and the gate was quickly closed again after allowing passage.

The man reined in his horse and galloped away, quickly disappearing from sight.

"Quickly, go and report to the county magistrate!"

The city gates were hastily closed, and the soldiers were in a hurry, so the atmosphere on the city wall suddenly became serious.

Flat mountains.

A carrier pigeon fluttered its wings and landed on Jia Yi's palm.

He took down the bamboo tube hanging from the pigeon's leg, and the four concise words made Jia's expression change instantly. He then knocked on Jiang Bai and the others' courtyard gate.

"My lord, the barbarians have invaded, and the border city has fallen."

"According to the news, a group of barbarian spies disappeared after entering the country."

Jiang Bai took the note, glanced at it, and narrowed his eyes dangerously.

"Is there any news of my mother?"

"return……"

Just as Jia was about to say no, a carrier pigeon flew hurriedly toward him.

"We have news."

After taking the message off the carrier pigeon's leg, Jia Yi's ordinary face suddenly lit up with joy, and he respectfully handed it to Jiang Bai.

Jiang Bai unfolded the letter, and three large characters appeared on the paper.

She felt a little relieved.

Her safety should be assured there.

If her safety is not a problem, why hasn't she come back?

In my memory, Mrs. Song loved her children very much. If she had nothing to do, she wouldn't have gone so long without contacting them.

Unless, something happened to her.

Jiang Bai's brows, which had just relaxed, furrowed again.

"Do you have any accurate information? Why was she there? And when did she appear there?"

“Carrier pigeons can only carry partial messages. Now that they have found the lady’s whereabouts, they must have already gathered all the information.”

"News will arrive soon."

"Okay, tell them to hurry up."

Jiang Bai nodded, knowing that transportation was inconvenient at this time, making it difficult to transmit messages.

But the situation of the Song family is indeed worrying.

"yes."

“Nan’an County borders the west, so let’s be vigilant. If we find any trace of barbarians, we should not show any mercy.”

"yes."

Jia Yi quickly withdrew to deliver the message.

With the border town breached, Xuchuan Prefecture, which is adjacent to the border town, went into a state of war preparedness.

After the border town comes Chongyu Pass. If Chongyu Pass is breached, then Xuchuan Prefecture will be next.

Of the three prefectures of Xuchuan Prefecture, Yingzhou is closest to Chongyu Pass, and among them, Nan'an County is even closer to Chongyu Pass.

As night fell, Prince An came to see Jiang Bai again, bringing with him the sheep wool that he had ordered his men to collect.

He had the space, and the sheep wool he brought at one time weighed a thousand pounds.

"Could these wools be woven into sweaters and supplied to the army first?"

When Mingyu first received the news, his first thought was that these sweaters could be used as military supplies.

Because of the shortage of cotton, many of the cotton-padded uniforms in the army are filled with cattail fluff. This is acceptable if the weather is not too cold, but now the weather is getting colder day by day.

If this continues, I fear that when the barbarians attack, the soldiers will be too weak to even hold their guns.

"Can."

“The sizes and weights used in the military should be the same. Give me the measurements, and I'll pick some skilled knitters from the surrounding villages to help me with the process.”

Sheep wool is much more difficult to process than other types of wool, and the procedures involved are far more complex than those for ordinary wool.

"Give."

Mingyu was prepared and handed Jiang Bai a piece of paper with the dimensions written on it.

Jiang Bai raised an eyebrow, realizing that the whole story about having a traveling merchant and a caravan among his advisors was a lie.

It's likely that a caravan was specifically formed to collect these sheep's wool.

"However, we can provide the sweater, but we'll have to discuss the price."

"I won't charge you much more; just 20% profit per sweater will do."

Mingyu gasped.

"Half a percent".

A 20% profit is practically robbery.

Besides, he still owes her a huge debt, and with an additional 20% interest, where would he get the money to buy it?

"Twenty percent is not much. Think about it, if the barbarians attack and Luzhou falls, the loss will be much greater than the gain of twenty percent."

"No, half a success, at most half a success."

Mingyu shook his head repeatedly.

He was so greedy that he wanted to stretch every penny in his hand in half. Although he didn't know how much the 20% Jiang Bai mentioned was, it was definitely not a small amount.

If we factor that into the expenses of tens of thousands of soldiers, it would certainly be a considerable expenditure.

The two struggled for a long time, neither willing to back down.

Ultimately, they reached an agreement on a 10% profit.

For each sweater, we'll give you a 10% profit.

After Mingyu left, Jiang Bai summoned Jia Yi and ordered him to pass on the message to the Xuanyi Guards to start building a sweater factory overnight.

Sheep wool requires processing, which involves complex procedures.

Without building a factory, it would be difficult for the villagers to complete the task on their own.

The Xuanyi Guard is full of talented people, including those in charge of construction, carpenters, bricklayers, and masons, with all kinds of craftsmen.

While factories in Pingshan were under construction, some villagers in Jiangjia Village at the foot of the mountain had successfully knitted a sweater.

After putting on the top, the village head's wife's eyes lit up.

"Honey, this sweater is warm, you should try it on too."

The sweater was knitted large enough for the whole family to wear.

The village head tried it on and a smile involuntarily appeared on his face.

"good."

Because it's loosely knitted, the wind can seep into your body through the hem.

He frowned.

"This sweater is different from others; it needs to fit well to be warmer."

He loosened his grip on the sweater, felt the wind slip in again, and frowned once more.

Every household used to make one garment too big so the whole family could wear it, but if a sweater was made too big, it wouldn't be warm enough.
