"You want me to set aside a piece of land for you in the Hibiscus Garden, and then you are going to build a academy on it?" Li Shimin took his eyes off the fold and looked up at Wu Yuanqing who was standing aside. Pen "Fun" Pavilion www.biquge.info

"It's not a academy, it's a school" Wu Yuanqing is not interested in the academy, and stubbornly calls it a school.

"Why?" Whether it is a college or a school, it doesn't matter what it's called, the key is that Li Shimin is very curious why his son-in-law would think of getting this.

Why, Wu Yuanqing pouted speechlessly, does this need to be asked, your family threw it at my house one by two, can you put it in such a big place in my house, the most important thing is that they are either princes or princesses, and they are running around, and my maids and servants can bend their waists just by saluting them, so that they have no strength to work one or two.

"The minister's family is small, and the environment is not as good as Furong Garden" Wu Yuanqing thought about the reason so casually.

Looking at Wu Yuanqing's perfunctory appearance, Li Shimin felt itchy and wanted to hit him with something.

"Okay, you want to make what you have learned useful, it's a good idea to pass on your knowledge, I can give you a piece of land for you to build a school, but what should be taught and what should not be taught, I think you should understand," Li Shimin said patiently.

"Understand," Wu Yuanqing smiled and nodded, "The ministers only teach them some basic things in arithmetic, and the important ones are definitely not taught, so Your Majesty can rest assured." ”

With the emperor's promise, Wu Yuanqing left the palace happily. When he got home, he called the housekeeper and asked him to prepare for the construction of the school.

"Husband, are you really going to run a school and teach in the future?" Wang Ziyu asked curiously.

"What do you think?" Wu Yuanqing asked rhetorically.

"I don't think that's like yours at all," Wang Ziyu pursed his lips and smiled.

"Hehe, my daughter-in-law still understands me. I built this school to drive those who come to the house every day to make noise, husband, I will go to school when I want to go to class, and if I don't want to go to class, I can hide at home" Wu Yuanqing smiled proudly.

"But this is not good, since the husband accepted them and promised to teach those students, he must teach them well, so half-heartedly I am afraid that it will cause His Majesty and the ministers who sent the children to be dissatisfied," Wang Ziyu said worriedly.

"What do they have to be dissatisfied with, husband, I didn't promise them all-weather classes, and their children don't have a choice to come or not. Like Li Tai and Li Ke, they don't have to learn from the gentlemen in the palace first, and then learn arithmetic in their spare time. Students can do this, do you want me, a gentleman, to accommodate students," Wu Yuanqing said angrily.

"Anyway, husband, I don't like to be a teacher to teach students, it's better if the students don't come one by one, so that the husband will have a lot of time to spend with you" Thinking of such an idle life, Wu Yuanqing laughed happily.

In order to let the students adapt to this situation of no teacher, when Li Tai and Li Ke came one by two the next day, Wu Yuanqing directly appointed Li Tai, who had learned mathematics very well, as the head of the study group, responsible for lecturing and teaching these numbers to the newcomers who had never learned Arabic numerals.

However, the name of Arabic numerals Wu Yuanqing was directly changed shamelessly, anyway, Arabic numerals were not invented by Arabs, and they had not been fully invented at this time, let alone systematic operation methods, so Wu Yuanqing directly named this kind of number Chinese numerals.

Li Tai liked this feeling of being a teacher, and accepted this glorious and not arduous task without saying a word.

By the time Li Chengqian took Changle to the martial arts, Li Tai had already officially taken up his post for half an hour.

"Hey, let Qingque teach you too, the teacher thinks you're too comfortable" Li Chengqian roared and squeezed before he entered Wu Yuanqing's courtyard.

"Comfortable fart, brother, I'm busy," Wu Yuanqing's voice came from inside.

"Oh, I'll go, what are you doing here" Li Chengqian jumped out as soon as he stepped into the house.

I saw that Wu Yuanqing was wearing two layers of thick masks in the house, squatting next to a large wooden barrel, and I didn't know what was put in the barrel, so that the water inside was boiling as if it was boiling, and there was a bad smell and smoke.

"I said, are you preparing to cultivate immortals?" Li Chengqian asked with a probing look in his head.

"Cultivating Immortals, have you ever seen an immortal cultivator in a bucket?" Wu Yuanqing said with a roll of his eyes.

"Then who knows, maybe your immortal cultivation technique is so perverted." Li Chengqian looked teasing.

"Get out" Wu Yuanqing scolded.

"Hahaha, no kidding, seriously, what the hell are you doing, why do you make the house smell so bad, you can't sleep at night?" Li Chengqian asked curiously.

"Get soap," Wu Yuanqing replied casually.

"Soap?"

"It's about the same as pancreas," Wu Yuanqing explained.

"Pancreas, what are you doing with that thing, it's dark, the palace maids in the palace only use it for washing clothes" Li Chengqian pouted.

"Take a bath" Wu Yuanqing popped out two words.

"You have a problem with your brain with pancreas for bathing, you see that rich and noble people use pancreas for bathing, and everyone uses honey locusts or bath beans." Li Chengqian said in surprise.

"You don't want to keep the pancreas good or not, I said that it is soap, but the effect is almost the same as that of pancreas," Wu Yuanqing said dissatisfied.

Li Chengqian said that the bath beans are the washing products that appeared in the Wei and Jin dynasties, that is, the dirty blood of the pig's pancreas is washed, the fat is torn off and ground into a paste, and then soybean flour, spices, etc., evenly mixed, and then naturally dried to become bath beans that can be used for washing purposes.

In the process of making bath beans, the pig pancreas is ground to enhance the exudation of digestive enzymes contained in the pancreas, and the mixed soybean flour contains saponins and lecithin, the latter has the effect of enhancing foaming power and emulsifying power, which not only strengthens the washing ability, but also moisturizes the skin. However, due to the difficulty of obtaining a large amount of raw materials such as pig pancreas, bath beans were only used by a few upper-class nobles.

As for the soaphorn, it is not a direct soaphorn fruit that ordinary people will use, but it is mashed and finely ground, added with spices and other things, and made into an orange-sized ball, which is specially used for washing the face and bathing the body, which is considered the soap of the Tang Dynasty at this time.

Spices are precious things at this time, and they can't be cheapened if they are related to spices, and naturally ordinary people can't afford to use them.

The pancreas that Li Chengqian disliked was a low-level version of the bath bean, not only using less pig pancreas, but also replacing the bean flour with plant ash and adding molten pig fat, so that the cost was reduced, but the pancreas also became black, the rich and noble people couldn't afford it, and ordinary people couldn't afford it, and only medium-level people would occasionally use it.

And the soap that Wu Yuanqing wants to make, in fact, strictly speaking, the production process is actually similar in terms of ingredients, but it is more improved, and the color is much better than the pancreas at this time.
