"Hmm!" Hearing Lu Chen's explanation, Li Yuan nodded, after all, there was nothing wrong with Lu Chen's words.

"What is the difference between this 'soap' and that 'soap'?" At this moment, Wan Guifei, who was sitting next to Li Yuan, asked with some curiosity.

"The biggest difference between these two things is that one has a fragrance and the other has no fragrance!" Lu Chen said with a grin.

"Wouldn't that be the same function?" Hearing Lu Chen's words, Li Yuan flashed his old waist, not only Li Yuan, but everyone else on the side was "flashed" by Lu Chen's words, and even looked at Lu Chen with surprised eyes.

Something that has the same function, just because one has a smell and the other doesn't, and then you divide it into two things?

"If it's in essence..."Lu Chen paused when he said this, Li Yuan and the others were all waiting for Lu Chen's next sentence attentively, and as a result, they heard Lu Chen's next sentence, "It's really about the same!" Even Lu Chen nodded solemnly in order to show that he was indeed really.

"Cut!" Hearing Lu Chen's words, Li Yuan didn't roll his eyes because of his face, as for Wan Guifei, she had a speechless expression, and the others rolled their eyes in unison.

"Your Majesty, although these two things have the effect of removing oil, their essence is still different!" Lu Chen and Li Yuan continued to explain.

"What's the difference?" Li Yuan looked at Lu Chen and continued to ask.

"This 'soap' was developed by the minister to replace the 'honey locust'!" Lu Chen saluted Li Yuan and said, "Governor Chang, please get another basin of clear water!" Lu Chen said, looking at Chang Bao on the side, Chang Bao did not answer Lu Chen, but turned his head to look at Li Yuan, after Li Yuan nodded in agreement, Chang Bao ordered someone to bring another basin of water.

"Your Majesty, please look!" Lu Chen was not polite, he directly cleaned the hand towel with oil stains just now with soap, and with the clean water became dirty, the cleaned hand towel was shown to Li Yuan by Lu Chen, and he saw that the oil stains on the hand towel had disappeared after being cleaned.

"It's really much better than honey locust!" Wan Guifei is not one of those ladies, don't look at it now, it is a concubine, at the earliest, she was a concubine of Li Yuan, so she knows a lot about these housework, so she has a very intuitive feeling about the effect of "soap".

"This soap is for washing clothes, and this soap is for bathing, so the minister separates them!" Lu Chen handed the handkerchief to the little waiter on the side, and the little waiter handed it to Chang Bao, Chang Bao presented the handkerchief to Li Yuan, and after Li Yuan took it, he looked at it with Wan Guifei, and they all nodded, and at the same time, Lu Chen's explanation was also heard by the two people.

"Since the effects are all about the same, why don't you just make soap?" Li Yuan looked at Lu Chen and asked with some confusion.

"Your Majesty, this soap is actually upgraded from soap, this soap can be used directly for bathing, but it will be damaging to the hair and skin, and this soap is the minister added some other materials to make it basically undamaging to the skin!" Lu Chen looked at Li Yuan and explained.

"Forget it! I don't understand what you're saying! Listening to what Lu Chen said, Li Yuan waved his hand directly, "In other words, this soap is for washing clothes, and this soap is for bathing, right?" Li Yuan looked at Lu Chen and asked.

"Your Majesty, exactly!" Lu Chen said to Li Yuan.

Li Yuan looked at the soap and soap in the box, pondered for a moment, and then looked at Lu Chen, just smiled and didn't say anything more, but that look made Lu Chen's heart tremble slightly.

"These two gifts are good!" At this moment, Wan Guifei on the side smiled directly and said, "Lu County Gong, I heard you say that there is another thing called perfume, is it the thing in the middle of your box, the glass bottle?" Wan Guifei looked at the bottles of perfume in the box and asked.

"Qi Yu Guifei, exactly!" Lu Chen said, directly picked up a bottle of perfume, opened the cork, gently dropped a few drops on the back of his hand, and then plugged the bottle, just a few drops of perfume, so that a rich fragrance wafted out of the hall, this aroma is much stronger than the smell of soap just now.

"This is also the fragrance of plum blossoms?" The fragrance wafted, Wan Guifei sniffed lightly, and then looked at Lu Chen with some surprise and asked.

"Qi Yu Guifei, this bottle is indeed a plum blossom flavored perfume!" Lu Chen replied with a smile.

"Lu Aiqing really has the means, they all say that the plum blossom fragrance is indifferent, I didn't expect you to be able to refine such a strong plum blossom fragrance!" Wan Guifei looked at Lu Chen, nodded and praised, but at the same time, her eyes shot a fiery gaze, staring at the perfume bottle in the box, because, until this time, Wan Guifei noticed that the appearance of each bottle was actually carved with a flower, and the bottle of plum blossom perfume was naturally carved with a plum blossom.

"Xie Guifei praises! This fragrance is specially prepared for Her Royal Highness the Princess! Lu Chen said very directly, and as soon as Lu Chen said this, the others directly widened their eyes, obviously surprised by Lu Chen's courage in saying this.

"As far as the minister knows, whether it is the petals for bathing or the fragrant clothes, the fragrance does not last, but the minister's perfume can be kept for a long time!" Lu Chen ignored these people's gazes and continued.

In fact, what Lu Chen didn't say in his heart was that the things in this box were all poured out of the base by Lu Chen, and it was a bit too difficult for Lu Chen to make these things in such a short time, just take the simplest soap as an example, the most basic ingredient of soap is oil, and the best source of fat is lard.

Although Zhuangzi has let Niu Deshun and Niu Xingye father and son open a pig farm, in such a short period of time, although the black pig has also begun to grow fat, it is just a pig used for testing, how can Lu Chen be willing to start directly!

Moreover, these gifts sent today are Lu Chen's preparations for Li Yanjun's entry into Lujiazhuang, in this world, the best money to make is women's money, not to mention, Li Yanjun is ready to sit in Lujiazhuang when Lu Chen goes to Gyeongju and conquers Liang Shidu, Lu Chen has already learned from Su Chang's mouth, and Lu Chen naturally wants to find something to do for his daughter-in-law.

What's more, on the same day, Lu Chen promised Li Yanjun that he would give her perfume, Lu Chen left Lujiazhuang, Li Yanjun sat in Lujiazhuang, and Li Yanjun probably didn't understand what he was doing in the workshop, but about "cosmetics", Li Yanjun definitely understood better than himself, a rough man.

Besides, Lu Chen thinks that what is the meaning of the money of those men of the family, and the money of the ladies of the family cannot be let go, this is called "rain and dew are evenly wet", and the most suitable person is naturally his own princess wife.

As for the current "perfume", it was made by Lu Chen with the flower water in the base, and the production of this flower water is much simpler than perfume, although Lu Chen is now a little guilty about using flower water to fool his future daughter-in-law, but Lu Chen has already made up his mind that when he finishes cleaning up Liang Shidu, he must compensate his princess daughter-in-law when he comes back.

"Your Majesty, this Lu County Duke is really a caring person!" Wan Guifei smiled and whispered to Li Yuan, but the tone of her speech was somewhat sour.

"This kid has a lot of ghost ideas every day!" Listening to Wan Guifei's somewhat sour whisper, Li Yuan glared at Lu Chen directly.

Li Yuan's eyes, as well as the way Concubine Wan looked at the things in the box just now, how could Lu Chen not see it, and directly saluted the two of them and said: "Your Majesty, concubine, today the minister brought two carts of things, one cart is a gift for Nacai, and the other is for filial piety to His Majesty and Concubine Niangniang, and the things on the two carts are basically the same!" ”

"Hmm!" Hearing Lu Chen say this, Li Yuan suddenly felt a lot better, after all, Wan Guifei sitting next to him is like this, today this matter will definitely spread throughout the harem, when the time comes, for the sake of Lu Chen's gift, those concubines in the harem will make trouble with themselves together, and it is estimated that they will have to be as big as a fight, and when they heard Lu Chen say that there is a car specially prepared for the harem, Li Yuan is naturally in a much better mood.

Next, Li Yuan picked up the things on the gift list and looked at a few gifts, including small vanity mirrors and the like, which made Li Yuan very satisfied.

By the time Lu Chen and Kong Yingda left the palace at the end of the ceremony, it was already noon.

"There is Lao Kong's old master, and I will prepare a little wine in Changyuan Building to thank Mr. Kong! I hope the old master can appreciate the light! Standing at the gate of the imperial city, Lu Chen said to Kong Yingda.

"Lu County has a heart, but the old man still has something to do, I'm afraid I will disappoint Grandpa Lu!" Kong Yingda looked at Lu Chen and politely rejected Lu Chen's invitation.

"Since the old master has something important to do, then he won't bother him!" Lu Chen nodded, and did not invite again.

"By the way, when I saw Lu County's gift today, the old man has something to ask for!" Kong Yingda was about to leave, but suddenly as if he remembered something, he stopped and looked at Lu Chen.

"Oh? I don't know what the old master commanded? Lu Chen looked at Kong Yingda and asked with some curiosity.

"The old man's second son, Zhiyue, has always been interested in medicine, I heard that Doctor Sun is now in the grandfather's mansion, and the old man intends to let Zhiyue go to Doctor Sun to listen to Doctor Sun's teachings, can the grandfather agree to this matter?" Kong Yingda looked at Lu Chen and asked very politely.

Hearing Kong Yingda's question, Lu Chen was slightly stunned, Lu Chen didn't expect that Kong Yingda would actually make this request to him.

"That's a good thing!" Lu Chen's heart moved slightly.

"Since Ling Lang is interested in this, how can he stop it! It's just..."Lu Chen said this, and groaned slightly.
