In the middle of the night, it snowed heavily, and the next morning, Zhu Wentian came out to pinch a handful of snow first, rub it, and shake his head.

"What's wrong?" Seeing that there was no one around, the chief asked in a low voice.

"I also want to cool down, the sudden cold air directly pushes away the transitional warm air, snow, can't have a snowball fight, and it doesn't form a group."

Zhu Wentian grabbed a handful of snow and pinched it, it didn't feel good, it was hard, it was similar to the feeling of cotton sugar and granulated sugar, and now it was granulated sugar, and it couldn't be pinched together.

If the weather is warm, it is the warm and humid air flow that rushes over, and the snow will form a ball when pinched, like a marshmallow.

This kind of snow is thicker, and if you pounce on it, people will fall.

Now it's thicker, and as soon as people pounce, they will shoot it, but it's uncomfortable.

Feel the temperature again, the wind is blowing, the northwest wind.

As such, tomorrow will be colder, and dry.

The lieutenant took out both the mercury thermometer and the alcohol thermometer and compared: "There is still a little gap, a difference of 0.5 degrees." ”

"Because our technology is not good, the alcohol is relatively accurate, and the village laboratory has worked hard to get the magnesium out to purify the alcohol, and the ferrosilicon will be fired normally like porcelain."

Zhu Wentian took a look at the two thermometers, there was a deviation, there was no way.

Alcohol he had worked hard to purify, including quicklime and magnesium.

The atmospheric pressure is then calculated using a pressure gauge that is raised from the depth of the water again and again, and in similar cases, the boiling of the water is compared with the ice-water mixture, and a numerical scale of zero and 100 degrees is given.

Now we actually need an extremely cold temperature, which is to reach a temperature of minus 40 degrees.

Because an alcohol thermometer can contain this temperature, while mercury cannot.

Then when the mercury thermometer reaches the limit, you can know how much error there is by comparing it with the alcohol thermometer.

This is in Celsius, and it's especially easy to extrapolate backwards after some data is known.

Of course, he can also make up another temperature unit and rules by himself, so that everyone else will listen to him.

But no, it will disrupt his knowledge structure, he is learning such a system, after changing, he has to change according to the change, for what?

"Hanhan, it is the most effective way to hatch eggs of chickens, ducks and geese, and it is also useful to see if people are hot.

When we get back to the north, it's best to get below 40 degrees Celsius in winter, so that the mercury thermometer can't measure it.

In this way, we can produce a lot of thermometers normally and use them in key places in Daming. ”

The lieutenant took out a few more thermometers and compared them with each other, all of which hovered between 0.5 degrees of error.

"On the way, try to purify the kerosene, and then get out the kerosene thermometer, and it can reach minus 30 degrees."

Zhu Wentian wanted to make some kerosene thermometers to use as a comparison, but kerosene was actually not allowed.

"We can't let the crown prince and King Qin get sick from the cold, let's come and test some things, but also to ensure the stability of others.

Anyway, I'm not used to it now, I haven't been so cold when I was in Nanjing, no wonder they all say that northerners don't want to take a bath, what kind of bath is this? ”

The lieutenant said and sent the thermometer back, he hadn't taken a bath for several days, and he used to be in Xiaqiu Village, and poverty had nothing to do with bathing.

Next to the river! Everyone knows how to swim, go down and swim in a lap, and then it's time to take a bath.

Now there is also a river next to it, jump in...... It is estimated that it will be too cold to get up.

"When you enter the desert, there is no shelter around, and when the cold wind blows, you can really feel what it means to be cold."

Zhu Wentian rubbed his hands on his body, and then the two sleeves of the military coat were closed, and his forearms were inserted together.

"Without a cold bone, how can you get the fragrance of plum blossoms?" The long one followed a sentence.

"There are no plum blossoms in the desert! Once you go in, you will know that the strength of taking a step will be unloaded by the sand, which is different from walking on the hard road of flat ground.

The logistics have to keep up, Zhu Biao and Zhu Fan have to get down and go, and if they can't take the car, they will store the car before they enter the desert.

Our village wants to buy camels, buy them separately, and use them for our village's car, the prince's car can be without, and our village's can't do without.

As long as you give more money, there are people who are willing to sell camels, and we put skateboards under the cars in our village, and drag them without turning. ”

Zhu Wentian got serious, Zhu Biao and Zhu Zhang's cars and chariots would be thrown down, and the others were the same, they could only rely on horses and people's backs.

If there are no cars in the desert, there should be no cars.

Xiaqiu had to buy more livestock, especially camels, and then add skateboards under the wheels and drag them along.

The car cannot be thrown away, and with the car in Xiaqiu Village, it can ensure the chance of survival in extreme conditions.

It has a set of laboratory equipment and a lot of state-of-the-art technical equipment that should never be thrown away.

"The people around the desert have less livestock, especially camels." The governor considers the problems of the people.

"What's the use of winter? Sell it to us first, oops! I'm about to meet the team coming over there, just right, change with them. ”

Zhu Wentian said that he thought of the 100,000 troops who came back, escorting the prisoners! It's almost time for the position.

On this route, there must be a large number of camels in the team that returns, and the cattle will be given to the other party in exchange for the other party's camels.

……

Two days later, the team finally met someone from the other side.

As soon as everyone arrives, whether it is cold or not, drink water first, including the captives.

"His Royal Highness the Crown Prince and His Royal Highness the King of Qin, it's better to take a detour!" Liu was scared.

Seeing the appearance of 100,000 soldiers and a large group of prisoners, I felt that this road was dead and alive in the past.

Because of the dead people, more than 100 of the Ming sergeants died on the way back, and more than 400 prisoners died.

Now that everyone knows about the coal mines, even the farthest people come to dig up the coal and bring it back.

Later, the people of the surrounding states and counties got the news and rushed over, and they didn't need to pay a penny for the coal here, so they could take it away if they were selected, and they could come and install it whenever they wanted.

"The cattle and some horses that can't go into the desert are already well raised, give them to them, and we'll take over their camels and stay for another three days."

Zhu Biao disagreed, how did General Xu Da rush?

I can also adjust, the Chinese army at that time did not adjust the time, just fought all the way forward, hard over the desert, and engaged the enemy just after the past.

Three days is the time for the camels to recover after crossing the desert continuously, and all the peaks have lost weight, but it doesn't matter, as long as they are given enough forage, water, and salt, they will soon gain weight again.

Now a lot of camels have been bought and fed as well as camels returning from distant places.

Soybean cake, bran, puffed barley and barley.

The camel is happy, what camel thorns and sand willows, stand aside, let's eat well today.

Yes, camels can actually eat camel thorns and other foods that normal people find difficult to swallow.

But it doesn't mean that camels can only eat these, give them better feed, and they won't eat camel thorns!

Feed the camel cactus and sugar gourd, as long as the camel has tasted a sugar gourd once, it will not touch the cactus.

At the moment, if you want to rush time, you will give the camels good food to eat, plus puffed food.

There is wheat bran in the water to be fed, and there is a separate trough with salt next to it.

The camels that came over ate like crazy, let's put it this way! They have never eaten such a good meal in their lives.
