In the evening, Tianjing began to seal off the city and roads.

People entering the city only need to go through a simple screening, and those who carry guns need to register their gun information.

Those who leave the city need to provide household registration information and have their weapons checked.

Anyone with Cenyang citizenship or who carries a new type of pistol manufactured in the Cenyang area within four years will be advised to return and will not be allowed to leave the city.

After recording, there will be more rigorous investigation and interrogation.

But all this has nothing to do with Chu Tianshu.

People like him are simply not within the scope of the Dayun court's thinking and pursuit of criminals.

——The girl next to Chu Tianshu who stayed with him in the hotel last night has a really special status.

Chu Tianshu hugged the girl's lap and embraced the brightest future. Unless he was sick, otherwise, he would not have any motive to assassinate King Chen.

Of course, the people handling the case were all normal people, even the smarter ones among normal people, so no one among them had ever considered that Chu Tianshu's brain might really be a little sick.

But in any case, it is a good thing for Chu Tianshu today that they do not include Chu Tianshu among the suspects.

In this way, he can save a lot of time for his own investigation work.

In the morning, I went to order some new clothes with Xie Ningzi.

In the afternoon, I went to see flowers and the sea with her.

In the evening, the two of them had a meal together.

Then Chu Tianshu sent Xie Ningzi back to the palace.

When we went to the Chiyang Iron and Steel Plant, the plant had been temporarily sealed off.

——His Royal Highness King Chen died, although from the known information, these people in Tianjing City have no suspicion.

But it was different from the way the late emperor died.

The late emperor died in an accident.

Although the imperial court determined that the cause of his death was assassination, and wanted to start a war with other countries.

But in the final analysis, there is no one directly responsible for the death of the late emperor.

But His Highness King Chen is not like that.

The death of His Highness King Chen was obviously an assassination attempt.

And he was shot.

This makes the nobles very worried.

Gun, this thing was originally Dayunchao's flagship product for external sales.

This thing has always been a weapon used by Yun people to deal with outsiders, and by gentlemen to deal with unruly people.

This time, a Yunren, a noble man died because of this.

This is very different.

Everyone needs to reconsider the positioning of "guns".

Therefore, these factories responsible for manufacturing guns may also need to suspend operations for a period of time, waiting for the princes of the court to discuss and reflect on this.

Therefore, before the results of the consultation are reached, all factories related to firearms and ammunition must suspend production.

However, the shutdown of work and production actually has little impact.

These factories that manufacture guns and cannons mostly receive orders from the imperial court.

And because the deadline set by the imperial court for the start of the war existed, in fact, the quantity of guns required by the order had already been manufactured.

Even if there are some gaps, it doesn't matter - there are plenty of defective products in the warehouse.

The fact that Dayun's court rushed to customize these guns was not because Dayun's army itself needed supplementary guns and ammunition.

These guns and ammunition are prepared for sale as goods.

Since they are not used by their own people, the court actually doesn't care whether the defective rate is high or low.

The actual customers of these guns and ammunition have no choice.

Those customers themselves need to purchase Dayun's guns and ammunition to fight against Dayun because they cannot defeat Dayun.

For now, this business is a forced buying and selling business monopolized by Dayun.

The actual quality of the goods is not important.

Chu Tianshu called someone to inquire about the closure of the factory, and then he felt relieved.

It's just a temporary suspension of production at factories related to firearms and ammunition.

Other factories are still operating.

With this thought in mind, he began to redraw the drawings.

This time, the drawing he drew was a basic model of an electric fan.

Electric fans are generally classified into many categories such as ceiling fans, table fans, ventilation fans, air conditioning fans, etc.

But overall, it works the same way.

It uses electricity to drive an AC motor to generate kinetic energy, drive the rotor, and drive the fan blades to rotate to form air flow.

So no matter what the category is, at most it only has a different appearance. As long as the core AC motor is formed, the rest are just simple appearances.

It didn't take Chu Tianshu long to draw the drawing of the AC motor.

After that, you should start making a physical motor.

This step requires the help of some workers and some coppersmiths.

Chu Tianshu then approached Old Liu, the janitor of Chiyang Iron and Steel Plant, and asked him to call several workers to come to the factory to help.

To be on the safe side, Chu Tianshu went to the palace again to inform Gu Feixue and Xie Ningzi that he wanted to make an electric fan.

Gu Feixue has never paid attention to gadgets like "electric fans" that are super redundant and have no application scenarios.

She is actually more inclined to treat this thing as a new technology and sell it to King Li.

"Miss Gu, I have always had a question."

"What's the question?" Gu Feixue asked.

"Dayun...as far as I can see, the degree of industrialization is not very deep."

"In industry, although three acids and two bases are already available, practical alloys can also be mass-produced."

"But industrialization has not actually reduced the cost of manufacturing many common daily necessities."

"When selling general industrial products, it seems that their manufacturing costs are not much lower than those of handicraft manufacturing."

"So why does Dayun still persist in fighting foreign countries and plundering dumping grounds for industrial products?"

"This?" Gu Feixue was stunned: "This... I don't know. Why do you ask?"

"Curious." Chu Tianshu smiled: "Miss Gu doesn't know, but it's actually nothing."

"It won't affect our work." Chu Tianshu thought for a while: "Miss Gu, is there a shortage of people in Dayun Dynasty?"

"It seems so." Gu Feixue nodded: "I remember it is like this, so every year we have to buy people from outside... But is this related to what you said before?"

"It doesn't matter." Chu Tianshu smiled: "Let's bring the topic back to the electric fan."

"Oh." Gu Feixue looked at Chu Tianshu suspiciously, wondering if he had gotten some secret information that he didn't know.

But then I thought about it, even if he got it, what would it matter?

If he wants to make money, he can't get around himself.

Thinking of this, Gu Feixue felt at ease again: "By the way, it's not very safe in Tianjing City recently."

"I'll ask someone to get some guns later, and you can bring them for self-defense."

"Can you use a gun?" Gu Feixue asked.

Chu Tianshu paused and looked at Xie Ningzi.

Xie Ningzi shook her head: "He has seen my pistol before, but he has never used it."

"Then you teach him how to use a gun." Gu Feixue waved his little hand: "Once you learn how to use a gun, it is always safer."
