The grandfather and grandson chatted for a long time, and on the same day, many officials came to pay their respects to Zhu Yunwen.

After all, Zhu Yunwen had been gone for so long.

After finally dealing with everything and returning to the East Palace, Zhao Qingzhu took a fan and fanned herself continuously, saying to Zhu Yunwen:

"The weather is getting hotter and hotter. I wonder if there are any good ways to cool down."

Zhu Yunwen nodded:

"It's too hot. We not only need to cool down, but we also need to quiet down some people in the world."

Zhao Qingzhu didn't understand what he meant and asked Zhu Yunwen in confusion:

"Who should we reduce the noise for?"

Zhu Yunwen told Zhao Qingzhu about the increasing number of brothels.

Zhao Qingzhu said to Zhu Yuntong:

“That really should be addressed. I think if there are too many brothels, the wine and women will drain the bodies of many men in the Ming Dynasty.”

If the government and the imperial court do nothing, this trend will only grow stronger and stronger, and may even become a mainstream phenomenon. At that point, it will be very difficult to control.

Zhu Yunwen naturally understood this principle, nodded, and said to Zhao Qingzhu:

"Tomorrow morning I will issue some policies to curb these malpractices. As for the hot weather, don't worry, I will find a way to cool you down."

Hearing Zhu Yunwen's words, Zhao Qingzhu was filled with hope. It was too hot, a problem that people used to think was almost unsolvable unless they could find a cool place to hide.

But even if you hide in a cool place, how cool can it really be?

The solution Zhu Yunwen offered was actually to make ice cubes.

He had wanted to make it for a long time, but he never had the time or the right opportunity.

Things are different now. It's so hot that I can't stand it anymore, so I might as well spend some time making some ice.

Anyway, even if he returned to the Ming Dynasty, it seemed there was nothing particularly important for him to handle.

So the next morning, both Zhu Yuanzhang and Zhu Yunwen attended the court session. Zhu Yuanzhang sat on the throne, while Zhu Yunwen stood to the side.

He first explained some of the important details of this voyage to the officials.

He then expressed his opinion, demanding that trade and economic exchanges with various countries be strictly controlled, and that no random or shady things be brought in.

We also cannot easily transfer some of our important core technologies abroad.

For example, steam engines and cement formulas are things that must not be easily leaked in a short period of time.

We should wait until the Ming Dynasty has fully mastered these techniques, leaving them hundreds of years behind, before handing them over to them.

Besides, even if we don't hand it over to them, the countries overseas will probably have already figured it out by then.

The officials all carefully noted down Zhu Yunwen's words. After finishing discussing the important matters of the court, Zhu Yunwen continued:

"When I returned from overseas this time, I passed through some places and discovered some malpractices. Late at night, several women came to the inn and knocked on my door, offering to provide special services."

This kind of thing may not seem strange or serious to many people, but it is not.

These things must be resolutely cracked down on. We cannot allow wine, women, wealth, and power to drain the men of our Ming Dynasty and leave them without backbone.

We cannot condone women engaging in such activities, otherwise sooner or later many women will come to believe that such things or this profession is normal.

In conclusion, we must establish sound values ​​and cultivate good moral character. Just because the people of the Ming Dynasty are now living in better conditions does not mean we can indulge in unrestrained enjoyment.

Therefore, from this moment forward, I hereby order that the imperial court and local governments must severely crack down on transactions involving money and sex.

Local brothels offering special services will also have to be closed and restructured; they can only offer singing and dancing, and no illicit transactions are allowed.

Zhu Yunwen's words sometimes carried more weight than imperial edicts, and the officials, upon hearing this, naturally dared not be negligent.

Soon, the Ministry of Revenue, the Ministry of Rites, and the Ministry of Justice joined forces to earnestly implement the order issued by Zhu Yunwen.

The Ministry of Revenue was responsible for ensuring that such places were absolutely not allowed to exist in any region.

The Ministry of Justice, based on these facts, formulated a series of criminal laws to execute those who violated them.

The Ministry of Rites was responsible for supervising these matters of propriety, morality, integrity, and a sense of shame.

Of course, the local government was responsible for the specific implementation. At first, when this policy was announced, many men were very unhappy about it.

But there was nothing they could do. No matter how unhappy they were, could they really defy the policies of the Ming Dynasty's crown prince?

Moreover, even the most displeased person understands that the actions of the Ming Dynasty's crown prince are correct and quite reasonable.

After calming the men of the Ming Dynasty, Zhu Yunwen ordered his men to bring in a large quantity of saltpeter.

That's right, in this hot summer, he plans to make ice using saltpeter.

Making ice from saltpeter is no secret; it was actually discovered as early as the late Tang and early Song dynasties.

However, since it wasn't anything particularly impressive, and given the limited information available at the time, it didn't spread.

This means that people who need it are unaware of it and don't know how to make it.

Those who don't need it won't pay any attention to it if they accidentally discover it.

At this moment, Zhu Yunwen prepared to carry forward this technology.
