Playing intrigue is worse than engaging in infrastructure

"Did Mobei Wang and his party come to Huijing from Wangcheng?" Song Qingyuan thought of a new possibility.

"Return to Your Highness, it is not." Jiang Duo said. "The scout reported that the king of Mobei had just quelled the rebellion of the Hunke tribe a while ago. If the troops were sent back to the royal court first, and then from the royal court to the Southern Zhou Dynasty, the distance would be greatly increased."

On weekdays, the scouting reports were first sent to Qin Zizhen by a special person, and after being sorted by Jiang Duo, they were sent to Song Qingyuan.Therefore, it is not surprising that Jiang Duo knew about Mobei.

Song Qingyuan nodded, motioning for him to continue.

"A small guess, the king of Mobei should have directly led some people to pass Xiaoqingshan and come from Wumeng in the Southern Zhou Dynasty." Jiang Duo thought for a while, "The road around Xiaoqingshan is difficult and dangerous, but Wumeng left Huijing. But the distance is only four or five days. Therefore, although this road is a bit difficult, it is the most time-saving one."

Hunke tribe... Song Qingyuan quickly recalled the map of the six states in his mind.

He knew this route. Mobei and Nanzhou were separated by a small green mountain. To the west of the mountain was the Hunke tribe, and to the east was the land of Wumeng.

Song Qingyuan recalled the information about the terrain of Mobei in his mind, and slowly said: "The terrain of Mobei is complicated, and the area where the Hunke tribe is located is at a high altitude. If you come directly to Huijing from Hunke, the horses may be drunk." oxygen."

The road in Xiaoqingshan is remote and rugged, and there are few people on weekdays, so naturally there is no post station for changing horses.But this section of the road is also the place where the horses lose the most.

Therefore, the horses needed for carrying people and carrying goods on the way for King Mobei and his party should have been prepared directly in the Hunke tribe.

"Your Highness, what is this "drunken oxygen"? "Jiang Duo asked with some doubts.

He can understand the word altitude, and His Highness explained it to him before.But drunk oxygen was unheard of for him.

Only then did Song Qingyuan realize that people in ancient times lacked sufficient understanding of altitude sickness.

Since the Han Dynasty, some people have been aware of the existence of altitude sickness, but the cause of altitude sickness has always been limited to "miasma".There have been no breakthroughs in prevention and treatment.

This cannot be blamed on them. After all, research on the composition of air did not progress until the 18th century.

Obviously, the current level of science and technology has not yet reached the stage of discovering "oxygen" in the air.

Song Qingyuan spoke carefully, trying to explain to Jiang Duo, who knew nothing about air, what drunken oxygen was.

"We have been living in an invisible and intangible air. The process of breathing is that the body is absorbing certain substances in the air. Some people call this substance oxygen."

Song Qingyuan paused, giving Jiang Duo time to understand.

"Different regions have different amounts of oxygen in the air. In areas with high altitudes, the oxygen content is low; in areas with low altitudes, the oxygen content is high."

He tried his best to explain to Jiang Duo in a language that people of this era could understand.

"If a person first comes to a place where the oxygen content is different, there is a high probability of getting sick. This is true for humans, and it is also true for animals."

Song Qingyuan didn't know if Jiang Duo could understand, so he could only try his best to explain.

If he can't understand this way, he will do it himself and do a few small experiments for Jiang Duo.

Jiang Duo thought about it for a while, then tentatively said: "I heard from the caravans in Yunzhou that some merchants from the Central Plains would feel dizzy and short of breath when they first went north. Could it be related to the oxygen content His Highness said?"

Song Qingyuan smiled and said, "Jiang Duo, you are so smart!"

When ordinary people hear something they have never heard of for the first time, whether they want to believe it or not, they always have to think for a long time.

But Jiang Duo not only quickly understood the principle, but also drew inferences from one instance, and thought of the phenomenon that had occurred before.

Instead, Jiang Duo can be trained in the direction of scientific research... Song Qingyuan thought.

Jiang Duo was also amused, obviously still not aware of the development direction His Highness planned for him, "Then does His Highness have a way to deal with it?"

King Mobei and his party should all be riding strong horses.After a few days, there is no relief, which shows that the symptoms have become more serious.

But such things as drunken oxygen can be treated through hyperbaric oxygen chambers in modern times.In ancient times, there was really no good way except to eat some antioxidant fruits.

"Maybe it's okay to feed some apples." Song Qingyuan said uncertainly.

In the original world, crisp and sweet apples were not grown until American missionaries came to China.But now in the Southern Zhou Dynasty, there are already large-scale planted apples.

Song Qingyuan sighed silently, and gradually accepted the fact that he had traveled to a completely strange world.

The only good news is that there are many similarities between this place and the world I know.Otherwise he will really collapse.

"Then do you want to send someone to remind the people in Sifang Pavilion?" Jiang Duo asked.

"No, just remind those Mobei people when you find an inconspicuous place later."

Song Qingyuan didn't have a good impression of the Sifang Pavilion, where he tried to figure out what Emperor Hongde was thinking when he first came to Huijing, and frequently picked on him.

How urgent is it for him to save the Sifang Pavilion?Let's talk about it in the next life.

"Calcinating limestone on the upwind of the stables may also be useful. If they want to, they can try it." Song Qingyuan added.

Since drunkenness is due to high oxygen content, calcined limestone can produce carbon dioxide.If it is calcined at the upper tuyere, it may have some effect.

"Okay, I'll make arrangements for the younger one." Jiang Duo turned around and was about to leave.

Song Qingyuan stopped Jiang Duo and asked, "Why don't you ask me why I did this?"

After all, Song Qingyuan intends to train Jiang Duo in scientific and technological talents, so of course he cannot let go of this ready-made teaching opportunity.

Although Jiang Duo thought in his heart that he only had to follow His Highness's instructions.

But since His Highness had already spoken, he still stood there obediently and listened to "what is carbon dioxide" and "the origin of calcium oxide" for a long time.My mind was numb when I left.

"Your Highness, the small matter of the horse has been taken care of. They have a good attitude. I followed your instructions and told them that this method may not work. But they still gave a dozen silver coins as a thank you."

Jiang Duo was quick to handle the affairs, Song Qingyuan's orders in the morning, he had completed them just after noon and returned to his orders.

"It's generous." Song Qingyuan saw that Jiang Duo was taking out those silver coins and was about to hand them over to him, so he quickly waved his hand to let him put them away, "Am I still short of those silver coins?"

Just as Jiang Duo was about to speak, he saw that the ice in the ice cauldron inside the house had almost melted, so he hurriedly asked the servant to replace it with new ice.

"Although Your Highness does not lack these ten or so silver coins, the small ones must not be deceived a little." Jiang Duo said while taking out the iced fruit from the ice cauldron and putting them on the table.

"Your Highness, do you still remember the Zhuangzi we bought in the early summer of this year? This ice was sent by the Zhuang. The price of ice this year is very high, thanks to the fact that the Zhuangzi prepared a lot last winter, otherwise the ice alone would have cost a lot Money," Jiang Duo said casually.

"This summer seems to be extraordinarily long." Song Qingyuan said tentatively.

Originally, he thought that the seasonal changes in this world were different from those in his previous life.Didn't expect it to be abnormal weather?

"Yes, Your Highness." Jiang Duo sighed, "It's going to be hot everywhere soon. Logically speaking, it should cool down slowly these few days, but it's still very hot today."

This kind of weather fully reflects the wisdom of Emperor Hongde.

I don't know how he found such a mansion that is cool in winter and warm in summer and given to Song Qingyuan in this place where every inch of land is expensive and full of royal mansions.

"In such a hot weather, I am afraid that the people's life will not be easy. You go and tell the shopkeepers of a few shops to set up some sheds around and cook mung bean soup for the people around to drink to cool off the heat. The cost is from my private treasury. Just take it."

Song Qingyuan continued to instruct Jiang Duo, "By the way, see if there is any suitable place to dig a well near the houses we have. If there is, after reporting to the Sub-district Department, we will ask someone to dig a well for the traffickers and the surrounding people. Get some water."

"There should be a few places that are suitable. The small ones will immediately arrange for someone to look at them." Jiang Duo quickly responded.

Now, as a proton, he is restricted everywhere.Even if it is to buy a shop and a house, it is necessary to use Zhuangzi's identity as the manager of a distant relative as a cover, and this matter should not be publicized.

Fortunately, Jiang Duo was extremely prudent and considerate in his work, and Song Qingyuan was very relieved to entrust these matters to him.

After arranging these things, Song Qingyuan nestled in the soft couch, searching in his mind about the methods he had read about the ancients' methods of escaping the heat.

A row of pillows was placed on the soft couch, which Song Qingyuan asked the surrounding farmers to collect a lot of duck and goose down.

Goose down pillows are extremely troublesome to make.First, clean the collected fine fleece with soapy water, and then dry it by drying.

Not only that, but also find a way to solve the problem of running hair.

In order to solve the problem of hair loss, Song Qingyuan asked some embroiderers in the house who were good at needlework to use a lot of silk to sew a pocket with several layers of fabric superimposed.After stuffing the duck down inside, let the embroiderers sew it tightly.

The outermost layer should be covered with a layer of dark silk as a pillowcase, otherwise if it gets dirty, it will have to be taken apart for cleaning.

These few pillows alone took him more than half a month.But the half-month wait was well worth it.

Smooth silk is wrapped in soft and fluffy goose down for a comfortable fit.

The only flaw is that this pillow takes tens of feet of silk cloth.The cost is too high, it can only serve the nobles, and cannot be promoted on a large scale.

Otherwise, he really wanted everyone to feel the softness of the goose down pillow.
