The fog and rain outside the window did not delay the flag, military hats, helmets and hats on duty in the Dongyang Military Government Office.

Rain will cool the weather, but to be honest, they don't expect it at all.

Standing guard is also a kind of training for them. Standing guard with your breastplate wrapped around your chest during the approaching summer is a torment.

It is even more amazing when it rains, because it is cooler. The generals will ask them to put on the cotton armor in their breastplate, tie their arms, cotton armor skirt, iron shin, and helmet without fully armed. They are more tiring than usual to stand guard and are not much cooler.

Wearing armor must also be adapted to local conditions. It is best to be fully armed. However, if heavy armor only has protection, it reduces the endurance of soldiers and causes non-combat reduction due to heatstroke, it is too much or too little.

After scientific considerations of the Military Office, during non-war defense duty, bird gun posts should be appropriately added to reduce armor protection; increasing armor in rainy and snowy weather and reducing firearms is a very suitable plan.

When garrisoned, their imaginary enemies were mainly rebels that might appear in the city. If the rebels lacked armor, even if they only had a minimum piece of breastplate, they could have an advantage in cold weapons fighting; if the rebels had sufficient armor, the firearm was the most effective force to deal with heavy armored troops.

On rainy days, the firing rate of the flintlock firearm will be significantly reduced from 80% to less than 50%. Even if a rebellion occurs, it will eventually be necessary to win by cold soldiers fighting. Fully armed heavy armored warriors will have an absolute advantage in defense.

Of course, for each unit, the specific training tasks of each thousand households are selected by the deputy thousand households from the practice.

Some deputy families like to train soldiers to wear armor and withstand heat, while others prefer the flag army that can skillfully fire bird guns on rainy days, so there are always abnormal actions.

The heat is the enemy of all the troops. In summer, how long can soldiers wearing twenty or thirty kilograms of armor fight?

Untrained men would destroy their bodies before they could even walk in front of the formation and could not even lift their swords.

There are only a few soldiers who have been well trained to fight for a quarter of an hour. Whether they are heavy cavalry or heavy steps, they will be exhausted. If they do not withdraw from the battlefield, they will stay on the battlefield forever.

How to solve this problem?

Usually everyone chooses not to fight.

But we can't just not train just because no one usually fights in the midsummer of busy farming. After all, their commander is a lunatic who always believes that he doesn't want to fight me at this time, and if I fight him, I have an advantage.

No one in the entire Eastern Military Palace suspected that Chen Mu would do anything that violated common sense.

The most uncomfortable thing to stand guard is naturally the flag army on guard in the Dongyang Military Government Office. They have the heaviest tasks and the officers’ requirements are naturally the strictest. Fortunately, they can still go to the Cangbingjiu in the Military Government Cafeteria to drink a cold drink, otherwise they will really not be able to live this life.

The ice cellar was built by Yang Tingxiang when he first came to be the governor. He first went to the cathedral and the armed square camp through the cellar of the Spanish Governor's Mansion to protect the Tibetan soldiers from the Spanish.

Later, he basically excluded the Spaniards in the city, and continued to dig downwards in the tunnel and the cellar, digging out three large ice cellars, using methods that have been passed down from ancient times in China.

The ice cellar is located deep underground, which is not affected by the temperature of the ground. There are five-foot-thick brick walls on the upper and lower sides. There are three natural insulation materials interlayers inside and outside the brick wall.

The outermost layer is filled with white ash, and then the cement brick wall is laid, and another layer of slag wall is added.

At the innermost layer, the insulation wall is built with sugarcane fibers. This layer is prone to moisture and decay and is not durable. The kiln must be demolished and rebuilt every year.

The ice cellars in the Ming Dynasty do not need to be made. In the winter of the north, ice can be cut directly from the lake and transported to the ice cellar to hide. The ice cellars in the official family are well maintained for complex insulation. The ice cellars built by the people themselves are simple and poorly maintained, but they can store ice for summer drinking.

Mocheng is different. People here have never seen snow. It is even more nonsense to transport ice from Majiagang in the north. They can only rely on the low temperature of the underground ice cellar to make ice.

Fortunately, the underground temperature is not high, so the consumption of nitrate does not require too much to create ice.

Therefore, the several ice cellars that have been repaired in the first year cannot be used. The ice cellars under the Governor's Mansion are best kept warm. The ice that has been left throughout the year is just enough to drink a glass of ice raspberry juice.

Ice production continued in the second year, and the room temperature of the ice cellar had become lower. During the ice storage process, some ice cubes melted and absorbed heat, making ice production less difficult.

In this way, by the third year, make five portions of ice, and by the second year, one portion can be left, so that the ice can be divided into other places and more ice cellars can be created.

When you make three portions of ice, you can leave one portion for opening the cellar the next year, and the ice cellar will be officially used. This is basically close to the maximum efficiency of the ice production of the cellar, and it will not take a few years to come.

Over the years, the temperature of the land a few meters outside the wall of the ice cellar will eventually drop below zero.

As for the generals, there are more ways to enjoy it.

In the lobby on the second floor of the Military Office, the inspector Pei Xiao and the short-tailed Leopard went upstairs together, crossed the threshold and saluted Chen Mu first. The short-tailed Leopard stood aside, and Pei Xiao stepped forward and said, "Master, I have brought the things."

"Take it in."

Following Chen Mu's words, several flag soldiers on duty brought in with a few wooden boxes, which led Chen Mu to get up and leave the seat, and went forward to open the wooden box.

He knew what Changsheng sent this time, it was cloisonné.

After Changsheng Official Kiln used Changsheng white clay to make porcelain, it once again made cloisonné enamel of excellent quality. This time, Changsheng Official Kiln sent samples, or they were not samples.

It is a prop to harvest Europa's wealth.

How beautiful is cloisonné? It is so beautiful that everyone can fascinate it. Even when porcelain enters the Ming Dynasty, where ordinary people enter the homes of ordinary people, cloisonné is still a symbol of wealth.

For Europe, which had just learned to eat with a fork for only two hundred years, porcelain can fascinate the nobles. If porcelain is compared to luxury goods for wealth, cloisonné undoubtedly has the status of diamonds in later generations and nuclear weapons in the war of economic plunder.

Changsheng sent not many cloisonné samples, a set of exquisite three-person cup bowls, basins and plates, and a four-legged lion-headed urn.

Chen Mu raised his hand and lifted the lion-head urn cover, looked inward, and asked Pei Xiao suspiciously: "Refrigerator?"

There is obviously a layer of insulation material added to the jar. If you put water and add salt to the smooth belly, you can use it as a refrigerator. Put a few cups of juice and drinks in it, cover it and drink it as a cold drink for a while.

Of course, this is only the eyes of the Ming people to discover its real purpose. Pei Xiao shook his head and looked at the short-tailed leopard teasingly, saying, "Go to Dashang, it's a refrigerator, but the short-tailed leopard said it was a jar for pickling meat. I guess Euroi felt the same."

"What's more, I heard that they didn't even have enough gunpowder to fight. Even if they knew the use, they wouldn't use it for iced water. It was used by Magistrate Zou for the Grand Marshal and would not be sold to the Europeans."

"No, this is done well, I want to sell."

Chen Mu's expression was very pious: "The Ming Dynasty was committed to improving the quality of life of Europeans. Our textile factory allowed European people to wear cotton clothes; our porcelain factory allowed European nobles to use porcelain tableware; now it is the official kiln that let their kings use refrigerators."

"Those nobles are willing to buy a printed plate for ten taels of silver. How much do you think our bald Spanish king is willing to pay for this?"

Chen Mu chuckled softly, walked around the hall, raised his hand and said, "I'll write a letter to Fei Laoer, telling him that I have something that can be used as a national treasure for him. I want to replace him with two thousand-quality ships in this set."
