In Chang'an, the convergence of the emperor's spirit has made Li Shimin obviously younger.

"Your Majesty, the national teacher has been found, and the national teacher is rushing back."

Yuan Tiangang was reporting Chen Nuo's news to Li Shimin, who had reviewed the recital.

"How much longer?"

Li Shimin put down the fold in his hand and asked about the situation.

"It's going to take about an hour and a half."

Yuan Tiangang pinched his fingers and calculated, giving a relatively accurate time.

"An hour and a half ......"

Li Shimin nodded, put down the fold in his hand, and walked off the desk and walked outside.

"Prepare the car, I want to go to the West City Gate, let the hundred officials prepare, and I will personally welcome the national teacher back."

"Yes, Your Majesty!"

A few quarters of an hour later, a convoy of nine steam cars with the Tang royal flag on the front of the car drove out of the city.

Li Shimin sat in a steam car in the center, blowing the air conditioner, watching everything that was booming outside.

"Electric fans, sell electric fans! 130 Wen an electric fan, let you get rid of the scorching heat of summer, enjoy the cool and beautiful summer! ”

"Electric fan, buy an electric fan! 130 Wen a ......"

Suddenly, a newly opened shop attracted Li Shimin's attention, and the electric fan sold by the store made him look like his eyes.

"Stop, let's go down and have a look."

When the convoy stopped, simple radio waves had already been applied, which was one of the reasons why Datang had been able to unite up and down and the army like an arm in the past few years.

"Your Majesty!"

"Your Majesty!"

Seeing the convoy stop, Li Shimin got out of the car with two attendants, and the surrounding people and shopkeepers hurriedly put down the things in their hands and bowed, from the reverence and excitement on their expressions, it can be seen that this salute is from the heart.

"You don't have to salute, you don't have to salute."

Li Shimin stepped forward to look at a fan that was spinning the wind at the door of the store, and stretched out his hand to turn a Fengshan that was not connected to electricity.

The fan blades are made of bent metal sheets, and the edges are passivated without cutting the hand.

"How did you invent this electric fan?"

Li Shimin asked curiously.

When Chen Nuo left, the restrictions of heaven and earth had not yet been unlocked, although electricity appeared through a small number of formation steam engines with generators, but because the formation steam engine could not be promoted on a large scale, the steam engine was generally used to drive production tools, and many convenient light industry products were not manufactured, among which the electric fan was one of them.

Of course, Chen Nuo played a relatively high-end game, and he directly passed the fan session and played with air conditioning.

Although the air conditioner also has a fan, or a more advanced silent fan, don't expect a group of people who still worship ghosts and gods and regard the steam engine as the power of the immortals to dare to disassemble and study it.

"Your Majesty, this is what I came up with on my own, I saw that there is a thing called an electric motor in the technical manual sold by the government, and it can be rotated when connected to the rotor of an electric motor.

Now that the weather is hot, I just thought of this fan blade structure, which can be driven by an electric motor to blow the wind.

I bought a batch of motors, asked a craftsman to customize these blades and bases, and finally assembled such fans. ”

In the face of Li Shimin's inquiry, the store that invented the electric fan simply said his invention skills.

Li Shimin nodded, and the eyes of some people in the surrounding crowd couldn't help but light up.

"Electricity can hurt people, how do you avoid electric fans from hurting people?"

Li Shimin raised a question, for him, the interests of electric fans are not important, the important thing is not to hurt people and cause safety incidents.

"Electricity travels through the metal and wet wood, so I wrap the motor and the wiring with a layer of dry wood, and the wood is covered with several layers of oiled paper to protect it, so that the electricity is not available to people."

The shopkeeper took an electric fan and pointed to the gap where the processing accuracy was not enough, and dry wood and oiled paper could be faintly seen in the gap.

"It's very good, install this fan in an Internet café, so that children will not be hurt if they accidentally touch it."

Li Shimin nodded approvingly, and pointed to the fan blades that were exposed without a trace of protection, and motioned to add a net.

Although the fan blades are passivated, there is still a possibility of cutting when running at high speeds.

"Your Majesty is wise!"

The shopkeeper was stunned, and then reacted and thanked him gratefully.

If something sold really hurts people, even if I am afraid that the family will go bankrupt, it will not be enough to compensate.

"In addition, if you report this electric fan invention to the Datang Technology Management Office, in the next two years, others will produce electric fans, unless the technology is completely different, otherwise you will have to pay a certain amount of money as an invention reward."

Li Shimin remembered that Chen Nuo once said that in order to ensure the rights and interests of inventors and to stimulate the people's enthusiasm for invention and research to the greatest extent, he put forward an opinion to this shopkeeper.

As an emperor, observing other people's emotions and psychology is the basic skill, just now when the store saw the specific manufacturing and invention process of the electric fan, the changes in the eyes of the people around him did not hide from him.

"This ...... Look at my memory, thank you Your Majesty, thank Your Majesty for reminding me! ”

The shopkeeper suddenly slapped himself, and his expression was full of gratitude.

Fortunately, Li Shimin reminded him that otherwise, a big business, an opportunity to make himself prosperous and rich would fly because of his own negligence.

"You deserve it."

Li Shimin nodded, turned his head to look at the people around him, and shouted: "Datang is developing and progressing all the time, technology and technology are changing with each passing day, in this era of Datang industrial explosion, everyone can give full play to their ingenuity, to explore and study more technologies, and invent more products."

Your technology and your invention can be reported to the Datang Technology Management Office.

As long as you are the first inventor, Datang guarantees your rights and interests, and anyone who uses your technology needs to pay a fee to you, and Datang will never let the inventor's efforts go to waste! ”

"This ......"

"Long live Your Majesty!"

"Thank you, Your Majesty!"

"Thank you, Your Majesty!"

The people and merchants around were stunned, and then shouted repeatedly.

After business and invention, they all understand that when they have an idea, an invention of their own, they have been thinking hard for a few years to perfect it and before they can make any money, the streets and alleys are already frantically imitating and copycating the despair.

Datang's decision is undoubtedly the biggest good news for businessmen like them.

"No thanks, this is what you deserve, this is the reward you deserve for your efforts."

Li Shimin waved his hand, and took a few guards to not get into the car again, but watched the development of the people along the street.

Heaven and earth are no longer limited, and when the right stage is used, the people will always burst out with amazing intelligence.

Electric fans, steel plates to the people to the supply of iron woks, sharper iron ploughs, iron hoes, and even simple bicycles, manpower tricycles, new looms, and so on can improve people's livelihood, improve people's clothing, food, housing, and improve production conditions of the products have begun to appear in the market.

Every time he walks in front of an invention that has not appeared before, Li Shimin will stop and ask, ask if he doesn't understand, and help put forward improvements if he understands that he has better opinions.

"Your Majesty, the national teacher is about to return."

Li Shimin was walking slowly, and Yuan Tiangang, who had been paying attention to the hour, walked to his side and reminded softly.

"I know, Playing Music, I'm going to go out of the city in person to welcome the return of the national teacher!"

Li Shimin's expression was solemn, and he ordered the left and right attendants to follow him.

"Yes, Your Majesty."

The attendant gestured.

Woo!

The loudspeaker standing in the center of Chang'an City made a different long sound, and a guard of honor holding flags appeared along both sides of the west city gate.

The sudden whistle and honor guard made the people of Chang'an City stunned.

This kind of whistle rhythm seems to be a joy in the management regulations of Chang'an City...... Could it be that the queen mother gave birth again?

No, the last time the queen was born, there was no such a big battle, is this time to report two?

"Xicheng! Let's go to Xicheng! The national teacher is back, the national teacher is coming back! ”

Before everyone could be confused for long, a group of people who came from Xicheng were preaching and explaining the situation.

The national teacher is back.

That mysterious anomaly is said to be the national teacher Chen Xianshi, who has lived for hundreds of years, and who guided Datang to become the first country of the human race and guided Datang on the road of industry.

Rumble!

The crowd roared, and the people gathered in Xicheng, wanting to get a glimpse of the national teacher who guided the Tang Dynasty to take off.

Time is too long, and everyone's memories are a little blurred, but the heirloom retained by some families in Chang'an is the formation steam engine that was once purchased from Chen Xianshi.

The greeting procession had stretched for several miles, and Li Shimin stood in front of the crowd with hundreds of civil and military officials, looking at the shining golden light in the sky.

"Your Majesty, there is less than half an hour left."

Yuan Tiangang thought lightly, and the golden light on the horizon was getting more and more abundant, and it seemed that it was about to appear in front of him.

Airplanes!

There was no wind around, and the space seemed to ripple, and the roar of a steam engine appeared, and a steam car roared from a distant official road.

"Ready!"

Li Shimin shouted, and the surrounding civil and military officials and soldiers of the honor guard were silent for a moment.

"Sir, shall we go over?"

In the car, the driver Bajie saw Li Shimin and a group of people from a distance, and after recovering most of his strength, he sensed the emperor's aura on Li Shimin, and asked Chen Nuo with a little fear.

Mom, this human emperor doesn't sit in the imperial city, why did he run out.

"Drive over."

Chen Nuo was a little surprised, and his face calmly motioned for Bajie to drive over.

This is to greet him.

Chen Nuo didn't expect that he had become the current first emperor of the human race, and Li Shimin would not forget his original intention and be a few miles away from the city to greet him.

Crunch.

The car stopped in front of the crowd, Chen Nuo took the little fox and got out of the car, and the monkey and Jiang Liu'er, who were sleeping on the roof of the car and disguised as humans, also got out of the car.

Li Shimin stood in front of the crowd, looked at Chen Nuo who stepped forward, and suddenly bowed down with the soldiers of the honor guard and the hundreds of civil and military officials of the Tang Dynasty.

"Shimin, welcome the return of the national teacher!"

"Datang, welcome back the national teacher!"

The voice was loud and resounded for miles.
