As time went on, the weather got colder and colder, and so far there have been a few snowfalls, and everything seems to be getting better.

Time is about to enter the fourth year of Zhenguan!

Du Ruhui's body is not as good as day by day, Li Shimin is worried about this, the messenger sent can even see the back of the previous envoy, countless precious medicinal materials are sent to Du Mansion one after another, but these medicines are almost useless for Du Ruhui.

Even a set of cotton clothes sent by Li Yuanjing made Li Shimin send to Du Mansion, and it was warm, but Du Ruhui's condition still did not improve.

Li Shimin's mood also became gloomy, and in addition, all affairs were carried out in an orderly manner.

At the end of October, the price of cloth in the Wanmin cloth shop was about to reach 100 yuan, and the store in charge of sales in the Guanzhong area was also about to reach 100 yuan, and the profits were no longer as rich as before.

But then came the closure of other cloth shops in the entire Guanzhong area, and they couldn't afford such a price, so they could only watch the weaving workshops rush out to transport the cloth, and it was said that the warehouse had no effect there, and just after weaving a piece of cloth would be immediately loaded and transported away.

Even so, the production capacity of the weaving workshop could not keep up with the huge market demand.

"Driving~~~"

The cold wind was fierce, the snow was falling, and the snow-white ground left chaotic horseshoe prints.

More than ten people, nearly fifty war horses, one by one wrapped themselves tightly, their mouths and noses hung with bursts of white ice, although they were very tired, but these more than ten people never stopped advancing.

Every quarter of an hour they would dismount and trot for a while, and when they were warm, they would continue their journey on another horse, and at night they would be repaired at the military station, and the next day they would return to their journey before dawn.

"The horse owner is thin, and it will be almost half an hour away!" One of the sergeants looked wearily ahead, his nervousness relieved slightly.

"Well, you guys hold on a little longer, and when you get to the camp, you can rest for a few days!" Ma Zhou also dragged his tired body and encouraged everyone around him.

Originally, Ma Zhou didn't have to go on this trip, but because the things in his hands were explained too quickly, he had nothing to do when he was idle, and it was just Li Yuanjing who hid in the palace Maodong at this time, which made Ma Zhou the most idle person in the entire palace.

Once people are busy, they will collapse when they are suddenly idle.

So Ma Zhou found Li Yuanjing, wanting to find something to do before the plan began, so as not to get sick.

So they were thrown here by Li Yuanjing, it was not easy for them to go north this way, or through the eldest grandson Wuji got a handwritten message from the confused Li Shimin, which was unimpeded and could rest and replenish at the military station.

The group continued to hurry, it was two days ago since the last correction in the post station, and it was a terrible thing to rush in this weather, if they didn't lack clothes and quilts, I am afraid that there would be attrition before they arrived at the place.

Nearly an hour later, Ma Zhou and Pedestrians faintly saw the shadow of the camp, and hurriedly rode over.

"Stop! Who are you? The captain on duty above the camp gate shouted loudly from a long distance.

"Bo Ma Zhou, the lord of King Zhao's mansion, is ordered to come!" Ma Zhou stepped forward and responded loudly, and at the same time put the oracle and the identity token into the hanging basket.

After about half an hour, several figures appeared above the camp gate, and Ma Zhou and others took off the hat on their heads and the cotton cloth covering their faces as required, and their identities were confirmed, and then they opened the camp gate to let them in.

"Master Ma, why did you get here?" Entering the camp gate, a smiling face was waiting for Ma Zhou over there.

"Sun Li? It's you! Seeing his old acquaintance, Ma Zhou's fatigue on the way instantly dissipated, and the smile on his face became a little more.

"The student came here directly after returning to the military mansion, and now he has been stationed in this place where birds don't poop for nearly two months!" Sun Li said with a smile.

Sun Li was one of the 100 medical officers who were summoned by Li Yuanjing for training a few months ago, but because they did not get the final shortlist, they were released ahead of schedule under pressure from all sides.

At that time, Sun Li's class was in charge of Ma Zhou.

These people know very well how much King Zhao attaches importance to Ma Zhou, and it is not easy to have this opportunity now, so they have always been commensurate with Ma Zhou, although Ma Zhou has not taught them any knowledge about medicine.

But a few months of training has helped them a lot, at least now these ninety-two people have all been turned into medical officers, and they don't have to go to the battlefield anymore.

Ma Zhou keenly grasped the key point in Sun Li's words, and couldn't help frowning, but the weather was too cold, and his forehead was numb from the cold after he had been on the road for so long.

"The army hasn't moved in two months?"

"No, but a lot of rangers are sent out every day, some come back, some don't come back, and the students don't know the specific situation." Sun Li nodded.

The immobility of the army is also a kind of consumption, and the daily need for grain and grass is innumerable, which requires countless labors to be transported from the rear one after another.

But Ma Zhou did not question Li Jing's decision in vain, Li Jing has experienced a hundred battles, and naturally has his own judgment on the battle situation, and there must be a reason not to move if he does not move.

But if Li Jing doesn't move, what should he do?

He is here to complete the task, and with the time on the way back and forth, His Royal Highness King Zhao gave himself a total of two months, that is to say, before the middle of the first month, he must return to Chang'an with these people.

"Are there any wounded in the battalion?" Ma Zhou hurriedly asked.

"Yes, but it's frostbite and headaches and fevers." Sun Li nodded and said.

Ma Zhou was a little entangled in an instant, it's not easy to do now!

I thought that this was the front line, where hundreds of thousands of people were stationed, and the war was imminent, and there would inevitably be enough wounded here to do the final experiment.

But after all calculations, even if it is not calculated that there is no war at all now, no matter how anxious Ma Zhou is at this time, it is impossible to urge Li Jing to get some wounded people to come out for him to experiment.

There are ten death row prisoners on the Chang'an side, but they were experimented as early as a month ago, six died within a month, and the remaining four survived smoothly, but the situation is not too good, although they are death row prisoners, Li Yuanjing doesn't want to squeeze them too much.

The reason why the front line was chosen is entirely because the wounded soldiers who need to use these are basically not alive, and the dead horse is used as a live horse doctor, in case of good luck and cured, it can be regarded as a creation, by the way, provide some experimental data, even if it is not cured, there is no need to have too much psychological burden, after all, if you enter the wounded barracks, about nine out of ten people can't get out.

"The horse owner is thin, the general is invited!"
