The weather gradually got hotter, and Li Shimin's qi illness flared up again.

The imperial physician in the palace was helpless about it.

Because Li Shimin knew that Li Su had excellent medical skills, he then brought Li Su over.

This disease of qi is tracheitis or bronchitis in later generations, in short, it is divided into many kinds.

Some can be cured, and some can't be cured at all.

And Li Shimin's kind is a stubborn disease, and there is no way to cure it at all.

Li Su could only take out some anti-inflammatory drugs and give them to Li Shimin.

However, in fact, the reason why Li Shimin's qi disease is so serious is mainly because of the environment.

The palace where Li Shimin lives is very old, but because of lack of money, it has not been repaired.

The palace was damp, coupled with the hot weather, and the disease of qi was even more serious.

And now, because Li Shimin has Li Su with him, he has finally made a little money, and he has the confidence to repair the palace.

Therefore, it was decided to return to the palace.

And Li Shimin decided to take advantage of the efforts to repair the palace and go out to escape the summer.

After making this decision, Li Shimin left a few old and serious ministers, leaving the crown prince in charge of the country.

I took the eldest grandson queen and Concubine Yang to escape the summer.

(In the fourth year of Zhenguan, Li Shimin escaped the summer due to gas illness and ordered the prince to supervise the country, which is a historical fact, not a fabrication of smoke and rain.) ）

Although he is the crown prince in charge of the country, Li Shimin has his own old ministers who stay behind.

After the crown prince Li Chengqian took charge of the country, whenever he encountered a major event, he would ask the eldest grandson Wuji, Li Jing, Fang Xuanling, Du Ruhui and other old ministers for advice.

The utmost respect for them also made the ministers very satisfied.

After the crown prince was in charge of the country, he was very diligent.

After Li Shimin's departure, the operation of the entire Datang institution did not come to a standstill because of his departure, but became more fluid.

And Li Shimin seems to have left, but in fact, every day's affairs, no matter how big or small, are passed on to Li Shimin.

Therefore, Li Shimin seems to be on a leisurely vacation, but in fact, he knows what happened in the Tang Dynasty and even in the court, and he has not escaped his control.

The departure of Tang Taizong has almost negligible impact on the people.

……

At this time, the weather is getting hotter and hotter.

On the streets, more and more people use folding fans.

As early as half a month ago, someone successfully imitated a folding fan.

Although it cannot be compared with the folding fan produced by the first hospital in the world in terms of quality, it is cheaper.

The folding fans produced by the first courtyard in the world cost 50 yuan each.

And other people's folding fans, the price of a piece is only five cents, more than that, and there are discounts.

With the advent of imitation folding fans, the folding fan business of the first courtyard in the world has been greatly affected.

Fortunately, Li Su had already expected this situation, so he did not rush to make folding fans in the later period, and at this time, their inventory was already very small.

Li Su simply disposed of the remaining folding fans at one time and stopped the folding fan business.

This kind of business, in Li Su's view, is just a fun and petty thing, and it can't be on the table at all.

For some reason, this summer came exceptionally early and was exceptionally hot.

Even if you hold a folding fan in your hand, all that comes out of the fan is bursts of hot air, and the hot sweat on your body can't stop at all.

At this time, on Chang'an Street, a small shop called Qingliang Yixia quietly opened.

This store has a couplet that reads: Come into my store to cool off the heat, and give you a cool summer.

Those gentlemen in Chang'an City, when they saw this couplet, their hearts were not smooth.

Huo, this tone is arrogant enough!

If you enter your store, you can beat the heat? Can you give me a cool summer?

What if you can't pay it back? Can you accompany me?

And the two sons and brothers who passed by recently are still famous gentlemen in Chang'an City, and they are Chai Lingwu and Fang Yiai.

The two men looked at each other, and then walked towards the store in understanding.

Hum!

If you can't cool off in your store, and you can't give me a cool summer, see if we don't smash your store today.

This shop is a little interesting, when I walked into the door, there was a curtain first, and when I opened the curtain, I found that there was actually a curtain inside.

When the two pushed the curtain, they found that the curtain was actually very heavy, and it seemed to be cotton flowers inside.

Well, it's cotton instead of cotton.

In the Tang Dynasty, the cotton used in later generations did not come out.

At this time, it is often used to come, it is cotton flowers.

Pushing open the curtain and walking in, the two of them suddenly felt a trace of coolness coming to them.

Hey? It's pretty cool in this store, even if it's their house, there are two ice cubes, and they don't feel so cool.

Entering my store to cool off, the co-author is really not deceiving.

However, they wanted to see how they could cool us down for the summer.

Chai Lingwu suddenly plucked his nostrils and asked, "Shopkeeper, how did you guys return me to a cool summer?" ”

After a while, a young man stepped forward, bowed down and said, "Two boys, in our store, there are only two kinds of food, popsicles and ice cream, which are made of ice. Once you've eaten it, it's going to be cool. ”

Oh?

It's actually a food made with ice?

This popsicle and ice cream, they really haven't heard of it.

When they are at home, they eat chilled sour plum soup at most.

Fang Yiai couldn't help but ask curiously, "How do you sell these popsicles and ice cream?" ”

The young man immediately introduced: "What about the popsicles, one hundred yuan for one piece, and five hundred yuan for ice cream." ”

Well, the price of a popsicle is equivalent to 200 yuan now.

Ice cream, it's a thousand dollars.

This price, I have to say, is too dark!

But the cost of ice making in Datang is really high.

The production cost of a popsicle, although it can be reduced in batches, but the cost price is about ten cents.

In Li Su's view, this is only ten times the profit, which is really a conscience price.

As for ice cream, in fact, there are more milk and white sugar, etc., and the cost is less than 20 yuan, which is the real profiteering.

Hearing this price, Fang Yiai couldn't help but be furious, and couldn't help but point to the young man's nose and scolded: "It's just food made of ice, which is essentially water, and you dare to ask for 100 yuan and 500 yuan?" Why don't you grab it? What the hell, you dare to blackmail your son, believe it or not, my son demolished your store? ”

As a result, before Fang Yiai's words were finished, an extremely arrogant voice was heard in the back room.

"Who? Who dares to make trouble in the king's shop? Someone, go and break his leg for this king, and throw it out! ”

As soon as the words fell, a few wolf-like guards rushed out from behind, and without saying a word, they stepped forward to set up the house and put it on the ground.

These guards are all masters in the army, and they have broken people's legs many times with Li Su, and they have already gained experience.
