Become the city lord from today

At noon, the weather in Chang'an City was exceptionally hot, and there were fewer people walking on the streets outside.

All of them took shelter in the shade of the trees, and some even fanned with large leaves of leaves.

Anlie stood by the window and looked outside, "Your Majesty, it's really hot outside." "

Usually fox-eared women like to lie on the glass, but because of the weather, the glass is a little hot.

"Yes, summer is coming." Liu Feng looked out the window and sighed, thinking that last summer's ice was made.

Mina walked to the window with a small electric fan and said, "People outside will be very hot without fans." "

The small fan she was holding was brought by Liu Feng from the earth, and there were not many of them, only the women of the castle used them.

"On such a hot day, it would be nice if everyone had fans." Allie muttered.

She considers that if there is less traffic, the goods will be easy to be unsold.

"It's not difficult to get everyone to have a fan." Liu Feng chuckled, it is not an automatic fan, it is still not difficult to manufacture.

"Huh? Isn't this fan rare? Allie wondered.

"You can make some manual fans and sell them." Liu Feng felt that this was also a business opportunity.

Summer is coming, the heat is unbearable for many people, and there are no electric fans sold in the other world.

It is also unrealistic to bring a large number of small fans from the earth, what should I do if the battery is dead? Today's technology can't make batteries.

And if the battery is brought more, it will also pollute the other world, which he does not want to see.

"Manual fan? How to do this? Mina wondered.

When the women first got the small fan, they all thought it was magic, how to press the switch will have the wind out, it is quite cool.

"Just need a few gadgets, let's go back to the castle and do it later." Liu Feng said softly, what is on a whim, let's do it when you are free.

"Okay." Mina nodded softly, and immediately processed the documents,

“........."

Time passed slowly, the sun set in the west, and it was already past five o'clock in the afternoon.

"Let's go, let's go back to the castle." Liu Feng got up and stretched, he was busy with government affairs all day, and now was the time to relax.

"Today's document can be considered finished." Allie also stretched.

Liu Feng did not change back into the imperial uniform, but lightly loaded down the eleventh floor, and when he went back, he would have to make a manual fan.

The crowd descended the highest building and returned to the castle under Mira's escort.

Liu Feng took a few women to the restaurant, and he wanted to go to the laboratory after eating.

After more than an hour, everyone had a spicy meal, and today they ate spicy, while the women did not eat spicy at first, and slowly now they have become spicy and unhappy.

"Nicole, let people brew some cold for them to drink, eat too much spicy." Liu Feng said gently.

"Yes, Your Majesty." Nicole nodded in reply.

Liu Feng got up and straightened his clothes and said, "Let's go, let's go to the laboratory first." "

"Good." Allie got up and said cheerfully, she had long been thinking about making fans.

"Crunch..."

A few minutes later, the door to the laboratory was pushed open by the maid.

Liu Feng took the lead to the experimental table, which had scissors, knives, and some wooden boards and the like, which were left over from Nicole's previous experiment.

Now many things in the laboratory are very complete, and there is no need to prepare anything.

Tisi looked at it curiously and said, "Your Majesty, how do you make this fan?" "

Every time they come to the laboratory to make something, they refresh their three views, and this time they are also curious.

"You need two gears, a fan blade, a handle and a fan handle." Liu Feng briefly introduced.

"..." Tisi and Weiya were all blindfolded, and they sounded complicated.

"Just watch me operate it and you'll know how to do it." Liu Feng chuckled, feeling very cute when he saw the confused looks of several women.

It is not difficult to make a fan and hand it over to the scientific research department, but when he has free time, he is still willing to take a little time to accompany the women, after all, everyone is usually busy, and there is less time to play together.

"The first thing is to make the parts." Liu Feng took a knife and carved on the wooden board.

The pattern of large and small gears is drawn on the plank, so just use a wire saw to see it out according to the pattern.

Ten minutes later, Liu Feng sawed out the gears and cut out the fan blades with cardboard.

"First take out the handle, which is the main body of the manual fan, nail a small gear to it, and then install the fan blade on the gear."

Liu Feng explained while operating, the speed was relatively slow, that is, so that several women could keep up, and said, "Install a handle on the big gear, and then fix it on the main body, and then add some moisturizer and shake the handle, and the big gear will drive the fan blades on the pinion to start rotating." "

"Your Majesty, is this all right?" Allie was stunned.

"That's pretty much it, just put a wooden board on top to fix the whole for safety." Liu Feng explained.

"What is the principle of this?" Weiya was curious.

"The gear drives the gear, and one turn of the big gear is enough for the pinion to go several times, which saves a lot of effort." Liu Feng explained patiently.

"That's how it is." Wei Ya nodded understandingly.

"Your Majesty, this is so fun, there is really wind coming out." Allie fiddled with the finished fan.

"Allie, let me play." Tis took the fan and tinkered with it.

"Your Majesty, can this allow the workshop to produce in large quantities?" Allie wondered.

After thinking for a moment, Liu Feng said softly, "Almost, but this fan blade is not strong with cardboard, let the workshop develop some relatively hard and firm materials to make fan blades." "

"Okay." Allie replied.

"And the fan master can also do some articles, so that the workshop can do some carvings on it, so that you can sell those rich people, those merchants and nobles prefer to be gorgeous." Liu Feng said after thinking.

"Understood." Allie covered her mouth and smiled, those merchants and nobles have very good money, as long as they make something that is different from high and low, they will definitely buy expensive.

"The rest is not too much of a problem, and you can also add some paint to the workshop to make the whole look better." Liu Feng added.

"It'll sell faster." Allie said crisply.
