After thinking it over, Zhu Yunwen realized that making money in ancient times was actually not easy.

Many things are impractical to make.

Just as he was at his wit's end, Zhao Qingzhu, who had come with him to learn about the wedding arrangements, said with a worried look:

"The weather is getting hotter and hotter. When the wedding is held, I will have to wear a thick phoenix coronet and embroidered robe. I'm afraid I'll be drenched in sweat. I might even smell of sweat. I'll definitely be the Crown Prince's wife who completes the ceremony with the smell of sweat."

Zhu Yunwen smiled:

"How could that be? I smelled it, and your sweat even smells sweet."

Upon hearing Zhu Yunwen's words, Zhao Qingzhu rolled her eyes and said:

"Then I'll have to wear a lot of sachets!"

However, Zhu Yunwen paused for a moment, then said to Zhao Qingzhu:

"Wait... a sachet? Perfume?"

Zhao Qingzhu asked in confusion, "What perfume?"

Zhu Yunwen looked at Zhao Qingzhu and said:

"By the way, the thing you usually carry around to cover up body odor, is it a sachet?"

"We all habitually carry a sachet with us, but the fragrance of the sachet is relatively faint. It is just a little fragrance left after some fragrant flowers have been dried, and it cannot last for very long."

After Zhao Qingzhu finished speaking, something came to Zhu Yuntong's mind.

That's perfume!

However, the production of this perfume would probably be much more complicated, and it would have been almost impossible to produce it under the conditions of ancient times.

However, there was one thing that Zhu Yunwen thought was acceptable: floral water, which was frequently encountered in later generations.

It's not entirely true that this stuff smells amazing, but its unique fragrance certainly outshines many perfumes, especially in ancient times.

Its fragrance is long-lasting and it keeps you feeling fresh in the summer, making it a truly excellent product.

Most importantly, even in ancient times, it was very simple to make.

The process is simply to find some common ingredients such as mint, honeysuckle, and musk.

Then soak it in alcohol, and after soaking, add distilled water to get the best ratio of fragrant, refreshing, and cool floral water.

Moreover, this item would have been an absolute bestseller in ancient times.

Because it also has another function: repelling mosquitoes.

Just think about it, this is a product that is simple to make and can be mass-produced. As long as it is sold at a slightly higher price than those sachets on the market, it will definitely become a hot-selling product.

Just spray some from this small bottle on your body, and you'll be protected from mosquitoes all day long.

It also helps keep you feeling cool and refreshed during the hot summer.

It can also emit a fragrance and mask body odor.

With these three functions combined in one, it has become exactly the kind of product that most people need in this hot summer.

Let's do it!

Zhu Yunwen took Zhao Qingzhu with him to the East Palace, took out all of his silver, and handed it to several Jinyiwei guards under his command, instructing them to prepare the necessary ingredients as quickly as possible according to the recipe he had written down.

Soon the Embroidered Uniform Guard bought everything Zhu Yunwen wanted, and then Zhu Yunwen began to make some distilled spirits and distilled water.

Add honeysuckle, mint, musk, and other ingredients to distilled alcohol and soak them.

Zhu Yunwen made dozens of vats of them.

Five or six days later, Zhu Yunwen opened a jar, glanced at it, and instantly a refreshing fragrance wafted out, filling the entire room with that scent.

Zhao Qingzhu, who had also come closer to look with a sense of doubt, exclaimed in surprise:

"What is this? It smells so good and refreshing. Just one sniff makes me feel so much cooler, and the whole room feels so much cooler."

Zhu Yunwen said with a smile:

"This is a good thing. I'll get you some to wear later, and you'll see how useful it is."

As Zhu Yunwen spoke, he used a small spoon to scoop out a spoonful of the original floral water solution and then mixed it into a large bottle of distilled water.

Distilled water is also purified water extracted through distillation technology. A spoonful of the original liquid was mixed with a large bottle of distilled water and shaken evenly. The original dark green liquid turned into a light green.

However, the fragrance of the diluted floral water did not diminish at all. On the contrary, due to the perfect balance of proportions, it was able to release the fragrance even more.

Zhu Yunwen poured some of the large bottle of floral water onto Zhao Qingzhu's body, then said to her:

How are you feeling?

Zhao Qingzhu said excitedly:

"It's so refreshing and smells so good. If I sprinkle this on myself, won't the whole place be filled with a refreshing scent?"

Zhu Yuntong nodded and said, "Of course, this thing is called floral water. It is used on the body in summer. The fragrance can keep mosquitoes away and relieve the heat, leaving a pleasant scent on the body."

On your wedding day, sprinkle some of this on yourself. Even if you're wearing a phoenix coronet and embroidered robe, won't you feel much cooler?

Zhao Qingzhu spoke up excitedly:

"That's true. This way, we don't have to worry about this problem anymore. I didn't expect you to go to such lengths to solve this small problem I mentioned."

Zhu Yunwen was immediately embarrassed, coughed, and said:

"It's not just to solve your problem; I actually have other uses as well."
