It was a scorching summer, and the empress's sudden move made all the people in the entire Tang Dynasty stunned!

Especially the residents of Chang'an, everyone had been curious about why the mansions of the adults were so cool, and it was not until the guards posted notices all over the city that people understood.

On the morning of this day, the soldiers in Chang'an City began to post notices all over the city, and in the east of the city, a group of people who went out for a walk in the morning were pointing around the notices.

"Ice, we can make ice in the middle of summer in the Tang Dynasty?"

"Saltpeter makes ice, what is saltpeter, and how is it made?"

"Illiterate, let you read more books, you don't believe it, and now you don't know a word. Isn't it written on the notice? saltpeter is a kind of ...... The way to make minerals is to add saltpeter to water......"

"Oh my God!"

"Hiss......"

Suddenly, there was a burst of exclamations, which made some illiterate people who were watching the excitement here look confused: "What are you doing? Why are you so shocked?"

"Isn't it ice? Your Majesty has always been open-minded, and you won't be so surprised to tell me how to make ice, right?"

However, the literate people scattered in a hurry, and ran away into the distance, leaving many 'illiterate' people with bewildered faces.

The Datang family is not wealthy, in fact, most of them are illiterate. Chang'an is an imperial city, and at the foot of the imperial city, there are more literate people, about one-third......

But the remaining two-thirds are really illiterate, and they don't know the characters in front of them, and they can't even write their own names.

At this moment, the literate people have all run away, leaving a bunch of illiterate people to catch the blind.

Half an hour later, an old man passed by, and because of his bad eyes, he watched and read on the sidelines, so that these 'illiterates' could understand what was happening.

"Everywhere in the city, there will be summer pavilions, and from now on, every summer, the pavilions will be opened. ”

"During the opening hours of the Summer Pavilion, all the people of the Tang Dynasty can go and receive a bucket of saltpeter for free with their ID names......"

Rumble!

Before Lao Suo finished reading, all the illiterates around him ran away in an instant, and similar scenes were constantly staged everywhere in Chang'an City.

Li Shangshu once suggested that the empress sell saltpeter in a royal capacity, and it is conceivable that saltpeter will inevitably become the best-selling item in the summer, so that the empty treasury can be filled just around the corner.

But after thinking about it, the empress shook her head and denied Li Shangshu's idea.

The entire Tang Dynasty, from the treasury to the ordinary peasants, is not rich. Except for a very small number of people, most of them are still stuck at the point of barely being fed and clothed.

If saltpeter is sold, even if the price is not high, it will inevitably cause a lot of burdens to the people of the Tang Dynasty.

After thinking about it, the empress put her heart on the horizon and simply gave it for free! Of course, this free supply is not an unlimited supply, but it is distributed to each household according to the capitation, and each person can receive a bucket.

Datang's bucket, according to Lin Zifan's estimate, is about six catties, if it is used all the time, it is naturally not enough for them to use it for a whole summer, but if you save a little use, plus it can be recycled, it will not be too bad.

At least two pieces of ice can be made every day to cool off.

And Lin Zifan also said that if every household in Chang'an City makes ice, there is no need to make much, and the temperature of the entire Chang'an will drop.

In this way, the empress was even more determined to give out saltpeter for free.

Of course, saltpeter is strictly forbidden to be sold privately, and if the private transaction is discovered, it will be arrested and put in prison!

In fact, before this, Lin Zifan had the idea of selling shaved ice in Chang'an.

In the hellish hot summer of Datang, selling some shaved ice or something, the business is definitely good. But after thinking about it again, Lin Zifan still gave up.

First, the method of saltpeter ice making will definitely not be hidden for long, and when the time comes, everyone will be able to make ice, and if you want to eat shaved ice, won't you make it yourself?

worked hard to invest in opening a store, but business turned out to be yellow in a few days...... What about playing?

Second, Lin Zifan has no money to invest, and his salary was deducted last month......

Just one day later, the temperature in Chang'an City plummeted! Although it was far from being cool and pleasant, as long as it was within Chang'an, the temperature in any place had dropped significantly compared to a day ago!

According to Lin Zifan's estimates, the average temperature in Chang'an is about 378 degrees, and the temperature in the palace and the 'first ring' where the adults are located is even lower, mostly below 35 degrees.

In other places, the temperature is not high, especially the slums, which used to kill the most people every year due to the heat, but now the temperature is close to the palace!

Without him, just because the slum is not a big place, but there are many people, everyone brought saltpeter back, and made some ice at will, and when the ice melted, the temperature naturally decreased......

On this day and night, Chang'an City, which was supposed to be hot and difficult for people to sleep, was exceptionally quiet.

The people slept very soundly, and for many years, there had never been a summer when they could sleep so peacefully and sweetly.

"I have never seen such a quiet night view of Chang'an in summer, I have never seen ......"

The empress wore a red dress, stood on top of the palace, looking at the entire Chang'an from afar, and was in a good mood.

"Officer Lin is indeed a strange person. On the empress's side, the national teacher Yan Ruyu sighed faintly: "I always thought that the person who could solve the scorching heat of my Tang Dynasty must be a strange woman through the ages, but I didn't expect that it was a man who solved this big problem!"

In fact, the two of them, and even the Manchu civil and military forces, are still a little incredulous.

Since the founding of the Tang Dynasty, the big problems that have plagued the civil and military forces of the Manchu Dynasty and all the people have been solved in this way......

"Perhaps, Officer Lin Logistics is an exception, right?" Ziyi on the side tilted his head and thought for a while, and said a word.

After hearing this, the empress and the national teacher both nodded lightly in agreement.

Over the years, they have definitely seen a lot of men, but someone as outstanding as Lin Zifan is unheard of.

"Officer Lin is a strange person, Your Majesty needs to pay more attention to it, don't underestimate him because he is a man. ”

The national teacher said: "Although the status of men has been low since ancient times, Your Majesty is a Ming monarch, so you should be wise." ”

"Throughout this period of time, the logistics officer of the forest first took out sanitary pads, which became one of the most important strategic materials of the army, almost second only to weapons, armor and grain and grass, and made great contributions. ”

"Now, it has solved the eternal problem of my Datang, with such merits, I am afraid that the sealing of a four-grade master is considered low. ”

"Not to mention him, he ......"

Halfway through speaking, the national teacher suddenly paused, looked at his 'proud' twin peaks, and coughed dryly: "I also invented underwear, which is really the gospel of our women!"
