Li Bao'er asked, "What kind of treasure is it?" ”

Cui Geng stretched out three fingers and said, "The first treasure, called perfume, is made from the essence of a hundred flowers, sprinkled on people, expelling mosquitoes and insects, and is fragrant. The second treasure, called soap, is used for bathing, which is not only far better than the pancreas and bath beans we commonly use, but also fragrant. The third treasure is called the bra. That's it, it's ......"

"What?"

"It's something that has to do with it."

As he spoke, Cui Geng had already stretched out the claws of Lushan, touched the snow-white piece on Bao'er's chest, and said, "The wonder of this thing is far better than Xiaoyi." ”

"Husband~~"

Li Bao'er was rubbed by him quite emotionally, and said in a greasy voice: "Erlang, why do you always have the idea of beating a woman's body with these three treasures?" Do you want the concubine to be tight and start talking nonsense. Let's still ...... Let's go to the couch. ”

"Gotta order!"

Cui Geng was like Feng Lunyin, picked up Li Bao'er by the waist, and walked to the bedside, and the room was full of spring.

……

……

In the following days, Cui Geng gave Li Bao'er a few big surprises, proving that the three treasures he said were not on the brains of the sperm, but they were indeed certain.

He proposed soap, of course, inspired by the indelible handwriting in front of the door today. It's not that hard to do.

In today's society, soap is made with grease and caustic soda, supplemented by spices. In ancient times, there was no caustic soda, and it could be replaced by ash water. The essence of plant ash water is sodium carbonate, and when combined with oil, it is enough to make the most primitive soap. If the effect is not good, you can also add some lime to get some not very pure caustic soda, which is enough to cope.

Perfume is simpler, just use alcohol to extract flowers. In fact, after Cui Geng made Mulan Spring Wine, there was no insurmountable technical difficulty in making perfume. The only thing that needs to be constantly studied is whether the thing produced is a flower water or a perfume, and what the fragrance is. This requires water grinding and constantly adjusting the proportions of various flowers.

When Cui Geng went to Fangzhou to welcome Li Xian back to Beijing, he asked to see Li Bao'er in the name of offering the three treasures. Among the three treasures is perfume, but she has never been told how to make it.

As for bras, this thing is simpler than perfume. I think that at the beginning, Cui Geng gave her the most primitive bra "Hezi" in order to chase Lu Ruolan, but now it is only a slight change in shape.

Lu Ruolan is a five-surnamed seven-wang girl, with a strict family education and pay attention to etiquette, so it is okay for her to wear "Hezi", let her promote it, but it will be difficult.

Princess Datang has always been known for being "bold", and Li Bao'er has no scruples in this regard at all. After she gave all kinds of bras to Princess Taiping, Shangguan Wan'er and even Empress Wei and others, the bras quickly spread in the upper class society of the Tang Dynasty.

What is good at the top will be very bad at the bottom. What's more, this bra is indeed both beautiful and good for crisp breasts? It didn't take long for the bra to spread quickly from high society to ordinary people's homes.

Of course, this thing really doesn't have any technical content, and there are many counterfeiters. However, Li Baoer mainly takes the high-end route. First, she has established a good reputation, and secondly, no one dares to snatch food from Princess Anle's mouth, and Li Bao'er has made a lot of money.

After opening the channel with a bra, as soon as soap appeared, it quickly swept the entire Chang'an City, and then won Yangzhou, Luoyang, Chengdu and other big cities.

The cost of soap is low, the profit is not low, but the price is not high, and the sales volume is huge. It's a lot better than a bra.

Of course, the best thing to earn is perfume. At Cui Geng's suggestion, Li Bao'er wrapped this thing in expensive packaging, and even gave it a nice name, called "Nine Heavens Jade Dew". The profit of perfume is dozens of times the cost, and it is really like making money like grabbing money. The most important thing is that this thing is not only liked by the people of the Tang Dynasty, but also by Hu Shang, who ordered it in large quantities and sold it overseas.

Li Bao'er made money, was in a very good mood, and went to see Cao Yuechan with Cui Geng, what she meant on the surface was to thank Cao Yuechan for her generosity in Dingkunchi, as for secretly pushing Cui Geng out, muttering for a long time, what exactly was being talked about, Cui Geng didn't know.

All in all, after this deep talk, Li Bao'er was very happy to look forward to it, and Cao Yuechan's face showed a long-lost smile, and there was no longer half of depression.

With sufficient money, the demolition work of Dingkun Pond is also going very smoothly.

Cui Geng's recent small life can be said to have been very smooth. The only thing that he was not satisfied with was that he mobilized the power of the secret hall, the Freemasonry and even the North Gate Society to track down the person who left the words on the door of the princess's mansion, but he found nothing.

Time is like an arrow, and in the blink of an eye, another three months have passed.

On this day, Cui Geng's mansion came to a distinguished guest, King Li Chongfu. It turned out that his title was the king of Tangchang County, and after Li Xian ascended the throne, he was promoted to one level and named the king of Chen.

That's it, there are still some people who are upset about Li Chongfu, saying that Li Xian's sister-in-law Li Chongrun is dead, and the three sons of the concubine are Li Chongfu, the eldest, and should be made the prince. Li Xian was noncommittal about these exhortations, and no one knew what was going on in his heart.

Outside the Jingzhao Yin Yamen.

Cui Geng bowed and saluted, "See King Chitose!" ”

Li Chongfu couldn't really let him bow down, so he hurriedly hugged each other with his hands and said, "Cui Xiang really tormented Xiao Wang!" Slowly, you are my brother-in-law and the prime minister of the dynasty, just because you saved Xian'er's life, I have to worship you first, right? To tell you the truth, Xiao Wang came here today to thank you. ”

"What's "you, you", you're too polite. Belch...... This place is not a place to speak, and the prince also invites him to serve tea. ”

"Cui Xiang, please."

The two entered the flower hall of the inner house together, and the guests and hosts sat down.

After a few words of greeting, Li Chongfu gave a gift list, and Cui Geng opened it, which was worth less than 1,000 yuan.

Of course, this wealth cannot be considered small, but if it is said that it is a thank you gift from the prince to the prime minister, it is really a bit shabby.

Cui Geng was puzzled, and secretly thought: Li Chongfu, don't be a big-tailed wolf if you don't have money, is my brother the one who lacks these two jujubes? Even if you want to express a light courtesy, you have to give something chic. These things in front of you are obviously all road goods.

Li Chongfu seemed to see what he was thinking, glanced slightly, and said: "Although these gifts are not very precious, they have a deep meaning, Xiao Wang has something to say to you slowly." ”

Cui Geng immediately understood, and said to the maids and servants who were waiting, "You all go down." ”

"Yes."

After a while, only Cui Geng and Li Chongfu were left in the house.

Cui Geng took a sip of tea soup and said, "It seems that King Qian came to see me, not so simple as thanks." What the hell is going on, let's talk about it. ”

Poof!

Li Chongfu knelt down cleanly and said, "Cui Xiang, ah, no, brother-in-law!" My dear brother-in-law, save me! If you don't stretch out your hand, I won't survive! ”

Cui Geng hurriedly jumped away and said, "Lord Wang, please get up quickly, in the end...... What's wrong? ”
