"Is that what they're doing? What are they? Li Shimin recalled the work of the farmers he had just seen, and asked with some curiosity.

Here is another quite deep impression left by the villagers, that is, compared with the other Zhuangzi villagers, these people in Linjiazhuang have a particularly high-spirited spirit.

Maybe compared to their previous life, their situation has changed a lot, and there are good crops, and there are so many promising industries in the future, not to mention that they are busy with these, just the lively oil mill on Zhuangzi can bring them a lot of benefits, that kind of soybean oil is now in demand in Chang'an City, it seems that the oil mill also has their share, and it is understandable that they are always jubilant.

Of course, if you let Lin Sen say it, Li Shimin is obviously undercounting, that is, the children of the farmers now have books to read, which is tantamount to a big shot of heart booster for them, so that they can find more and better heads, and they are naturally extra motivated.

When Li Shimin and the others returned to the tulou, they would probably be able to see this, and the louder and louder sound of reading aloud was easy to remind them.

Even those old farmers who go out to work hard must have left their children at home, and most of their wives are at home, and the children of the new farmers have inevitably opened a new class, and Lin Sen can't favor one over the other in this regard.

If it weren't for the unexpected discovery of two literate people among the newcomers, Lin Sen was not only temporarily liberated, but also took on the content of the cultural class, how could Lin Sen have that leisure and leisure, and he had nothing to do with Cheng Huaiyu to mix new perfumes.

"It's mainly two things." Lin Sen felt that these were all potential customers of his own, and they could also be used as gimmicks for external publicity, so of course he wanted to arouse their interest as much as possible.

"Needless to say, the raw materials are mainly the flowers and plants that I just saw that can repel mosquitoes, but the things made are very different.

I call this kind of circle by circle 'mosquito coil', as the name suggests, it is used to repel mosquitoes.

Compared with the original burning rope, this mosquito coil continues to burn for a much longer time, almost four hours, and it is enough to order such a plate in one night. Moreover, the mosquito repellent effect of this mosquito coil is much better than that of ordinary medicinal incense or burning ropes, and there will be basically no mosquitoes to disturb it. Lin Sen confidently introduced.

In fact, in ancient times, there were indeed things similar to mosquito coils, which may be related to the hygiene customs of the Dragon Boat Festival and the customs of burning incense and sacrifices.

Some insecticides such as realgar are added to ordinary incense sticks, which is one of the many medicinal fragrances, and some are dried with wormwood or artemisia grass and other herbs that have a certain mosquito repellent effect, and then woven into a straw rope and put it in the house to burn, that is, to burn the fire rope.

Realgar is actually the original arsenic, it is one of the most important insecticides in ancient times, drinking realgar wine, soaking in medicinal baths will use it, in order to remove insects inside and outside the body.

However, if it is used to make mosquito coils, it is also slightly harmful to the human body, and Lin Sen has replaced the main active ingredient of this mosquito coil with pyrethrum, which is relatively safer. Of course, in order to ensure the mosquito repellent effect, a reinforced version with the addition of realgar is also available.

In addition, such as mint and wormwood, willow bark and so on are also put some, in addition to their own certain insect repellent effect, can also be used as a binder, easy to make them shaped. In addition, in order to facilitate drying into the shape of large rings and small rings, a special grid is also indispensable.

"There is another thing I call 'flower water', which can be used to repel mosquitoes, but also apply to mosquito bites to help relieve itching, and can also be used to improve the awakening of the brain.

But I think women will prefer to carry this thing with them. Lin Sen smiled and took out another vial, poured out a little bit on the back of his hand, and then handed his hand to Li Shimin and let him smell it.

The aromatic ingredients here are naturally derived from the hydrosols left over from the distillation of plant essential oils, and then increase the dose of some peppermint, add a few anti-itching drugs, realgar is not necessary, pyrethrum is indispensable, to be precise, it should be called "mosquito repellent flower water".

"If it's really as good as you say, then you can prepare more mosquito coils, and you can send a hair to all the officials when you turn around. As for the flower water, you kid should also prepare some more and send it to the palace. ”

Under Lin Sen's signal, Li Shimin got some flower water and applied it to the temples, and immediately felt refreshed, and then considering the group of women in the palace, it was not good to be too favoritous, so he set a batch first.

With Lin Sen's consistent urine nature, the price of the mosquito coil should not be too expensive, but this flower water, if you want to send all the officials there, it will definitely be a lot of expenses.

"It's buying, not letting you contribute, look at your strength." When Li Shimin saw Lin Sen's painful expression, he answered with some unhappiness.

"That's good, the kid thanked Your Majesty first. What, after all, are they all the fruits of the farmers' labor, the kid has to think about them. Lin Sen immediately answered, and defended himself.

"Sure enough, it's not a family, and I don't enter a family." Li Shimin pointed at Lin Sen and shook his head helplessly, and nodded at Cheng Biting Jin again, which means that Lin Sen is about to become the same two-skinned face as Cheng Biting Jin, and he is still a dead man asking for money.

"You also know that the boy is poor, Your Majesty, this is the time to give a dowry, and the kid is really not generous." Lin Sen did not forget to appeal for himself with a look of grievance.

"Okay, you kid has grabbed all the money on my head, it's useless to talk about it. Let's go, it's time to go back to your tulou to see if it's really as solid as rumored, and let me see what a private fortress should look like. Li Shimin waved his hand to stop Lin Sen's words, and walked towards the tulou first.

"The boy is just a mud house with thick walls, but it is not a fortress, it can protect the villagers, not only thanks to His Majesty's care, but also thanks to the stupidity of the gang of bandits, if he met a general like the Duke of Yiguo, the boy would have fled with all the villagers."

Lin Sen hurriedly presented the sycophants, and by the way, he also expressed his loyalty, he didn't want to be detained as a private fortress, and he didn't have the heart to fight against Li Shimin, it was better to be a simple fierce general honestly, just his little heart, and he just expected to play with the real people present, it was better to be sincere.

Obviously, Li Shimin also understood Lin Sen's thoughts, and nodded lightly, which can be regarded as recognition in disguise.

"Well, this gate does take a lot of work, and it's a good place to defend and difficult to attack." After carefully looking at the various mechanisms of the gate, as well as the somewhat narrow corridor behind it, Li Shimin, who was already a master of the art of war, also praised Lin Sen's ingenuity.

"I just don't know what other good things you have in this building." Li Shimin rubbed his beard and said with some expectation.
