In order to make the outside world think that he was seriously injured, Yingxuan did not go out for a whole month. Pen "Fun" Pavilion www.biquge.info

In fact, at this time, he had recovered ninety, but the hot weather allowed him to enjoy it simply and reasonably for a month.

And in the two months of recuperation, it was the hottest time. The dog days are coming, the heat is coming, and Yingxuan, who has always been too lazy to think, also began to think about enjoying the coolness.

At that time, there were no air conditioners and electric fans, and hiding ice was the best way to escape the heat, and this method was often used in aristocratic homes, and ordinary families could not afford to use it.

Those who can afford it can build a separate ice cellar, such as the royal palaces in Chang'an, and the homes of some princes and ministers.

Yingxuan originally wanted to build one, but then when he thought about it, after it was completed, I was afraid that the summer would pass, and the gains outweighed the losses, the key was that he hadn't enjoyed it yet.

So Yingxuan asked people to fill wooden boxes with ice cubes every day and put them in the hall to cool off.

The effect is still there, but the ice cubes are consumed too quickly, and the supply is a bit out of supply when you use them.

Ying Xuan then processed the wooden box, and he ordered someone to make a small square cabinet, deliberately leaving a double lid, and then the cabinet was all wrapped with lead skin, and a small hole was left in the middle of the top.

Because lead conducts heat very weakly, this maximizes the use time of the ice cubes.

Small cabinets can not only cool down, but also refrigerate food and even lower the temperature of alcohol.

This is how the ancient "refrigerator" was created.

Ying Xuan still felt dissatisfied, although there were still some maids who would fan next to him, but the effect was not obvious.

So under the guidance and supervision of Yingxuan, the "mechanical fan" came into being.

The structure of the fan is very simple, just a few fan blades, a runner, a handle, and a base.

Of course, there are no generators.

Ying Xuan asked the family members to be the power, let them grasp the handle, like a hand-cranked projector, evenly and forcefully shake the "fan", and the fan blades can rotate whirring, producing a cool breeze.

But after a few days of trial, Ying Xuan is indeed much cooler when sitting in front of the fan blades, but the fans often sweat in a short time.

It was accompanied by a strong smell of sweat, which made Ying Xuan miserable.

In the end, Inspire improved the fan.

The wheel is removed and replaced with an axis, and then the fan blades are installed on the shaft, and the ropes are tied to the shaft, and the fan blades can rotate by pulling the ropes on the shaft.

In this way, the family can "fan themselves" from a long distance.

However, the above two types of fans have their own advantages, the former is windy, but you have to endure the smell of sweat; The latter has little wind, but the nose does not suffer.

As for which one to use, it depends on the specific situation.

On this day, Luo Wanshan came to report to Ying Xuan on the business situation of the day, and happened to bump into Ying Xuan lying comfortably on the soft couch.

There was a wooden box in front of him, and when I approached it, I felt a chill.

There was something like a screen behind him, but it was smaller than a screen, and it could be rotated, and a cool breeze would blow when it was close to it.

He was originally sweating, hot and depressed, but suddenly had a feeling of entering autumn. And since entering the hall, he never wanted to go out again.

Luo Wanshan saw that Yingxuan was sleeping soundly and didn't dare to wake up, so he looked around the two things and looked at them carefully with his hands behind his back.

The more I look at it, the more I praise it, and the people who can make these things are really amazing. If you have them earlier, can you be afraid of the scorching summer?

As soon as Yingxuan woke up, Luo Wanshan began to ask about the origin of "refrigerator" and "fan".

After learning that it was Ying Xuan's invention, Luo Wanshan's eyes widened in surprise, admiring Ying Xuan at the same time, he firmly believed that he had not followed the wrong master.

Immediately afterwards, he proposed mass production to Yingxuan, and the most outrageous thing was that he also suggested that these two things should be named after the word "Xuan".

Ying Xuan shook his head and rejected the proposal to name it.

Those are the crystallization of the wisdom of the ancient working people, and I only learned about them in my previous life, so I made them according to the gourd painting scoop.

However, it is possible to make money with these, and it is also a livelihood project, which is excellent for the people to prevent heat and avoid the heat.

Ying Xuan soon disagreed.

First of all, the production of the above things requires very tedious steps, in short, under the conditions of the Han Dynasty, large-scale production was impossible.

Secondly, since the process is cumbersome, the manpower spent is relatively large, so the price is relatively expensive, which is unaffordable for ordinary families.

Even if they are barely affordable, are they human-driven?

Apparently not, they were already exhausted by a busy day. Warm it up, it's hot, and rest is more tangible for them than anything else.

In the end, it was concluded that the so-called people's livelihood project is bullshit, and fans and refrigerators can only be "luxuries" that can only be owned by nobles.

So Yingxuan decided to produce only 100 units each, because the summer is about to pass, and it is unknown whether it can be produced in such a short period of time.

And things are scarce and expensive, too many of them don't show their value.

Ying Xuan also left a back hand in it, once a hundred units came out, it would definitely be robbed, and the aristocratic ministers who did not buy it at that time were bound to come to beg themselves.

At that time, according to their powerful position, it is determined whether to give them a separate creation, which is also a shortcut to quickly establish a relationship with the Chang'an magnates.

Snobbery?

I'm a real villain, why can't I be snobbish!

After Ying Xuan and Luo Wanshan discussed some specific details, they asked Luo Wanshan to do it.

He also instructed Luo Wanshan to send someone to Lu Lu's mansion immediately after producing the first batch, which was an attitude of loyalty to Lu Lu.

At the same time, it is also a signal that the next step is to deal with Lu Lu.

Before dealing with a person, it is better to let him down his guard completely, and then kill him with one blow.

For Liu Zi and Mrs. Chen, Ying Xuan did not plan to give them away, but only secretly sent someone to inform them and come to buy them in advance.

Before Lu Lu lost power, he had to be careful in everything, and try to avoid having too much contact with other people on the surface, especially Liu Zi, who had a hostile relationship with Lu Lu.

As expected, after the demonstration on the street, the first batch of fans and refrigerators were sold out in the blink of an eye.

And the people who made an appointment to buy it had already lined up in front of the store.

Time passed day by day, Ying Xuan's injury had healed, and he planned to go out for a walk and bask himself who had already been "moldy".

This is the first time since the injury that Ying Xuan has gone out, and the location was chosen in Luoyufang.

Cai Niang sent people to invite her three times before, but he politely declined.

This time it was different, Cai Niang came in person not to say, but also brought him a reason that he couldn't refuse.
