After packing up the stones, Zhang Yang put some small white stones into the water, tested the water absorption of the stones, and put them in the cart after confirming that the water absorption was not bad.

Today's Chang'an City looks extremely busy, and after a while, another team of soldiers and horses will leave the city.

The soldiers and horses went out of the city and rolled up a piece of dust, which annoyed people, and the infrastructure in Guanzhong was backward, when could the road be repaired.

One by one, notices were posted at the gates of the city, and the contents of the notices were written to expel all the Tuyuhun people in the city, and the Tuyuhun people could no longer enter Chang'an City.

It looks like it's really going to war.

The city is still bustling.

What should you do or what you should do.

Zhang Yang pushed the cart all the way into the city, some people were chattering, some were bargaining with vendors, and some neighbors were swearing at each other.

What a scene of fireworks in the world.

The tension at the border does not affect everyone's life in the slightest.

This is because the strong military strength of the Tang Dynasty has given such a kind of confidence, which only came after General Li Jing's victory in the Northern Expedition to the Turks.

It's like Datang has a patron saint.

If it was placed before the previous Weishui Alliance, maybe there would have been chaos at this time.

Zhang Yang struggled to push the cart back home.

Li Yue was busy in the kitchen again, and she had a stubborn energy in her heart.

As long as she wants to do something, she can't stop anything.

She held a small cookbook in her hand as she watched the recipe clumsily stir-fry the dishes in the pot.

The craft of stir-frying is simple and simple.

However, most of Datang's dishes are mainly stews.

After frying for a while, Li Yue looked up and saw Zhang Yang standing aside and watching the excitement.

Zhang Yang glanced at the pot and shook his head, "Put so much oil in the pot, you don't know how to stir-fry, you plan to fry the vegetables and eat them." ”

The little face was full of frustration, Li Yue put the spatula aside, took his small notebook, and stood aside with a pout.

Fortunately, there is enough lard at home.

Otherwise, it will be all the disaster of the little daughter-in-law.

Pour the oil in the pot into a bowl, the oil can't be wasted, and the dishes are already charred and obviously inedible.

After adjusting the heat, put the washed vegetables in the pot.

Li Yue recorded something in the recipe of the small book.

Zhang Yang took a look at it.

Li Yue reacted quickly and covered the recipe.

Then the girl walked back to the courtyard with the minibus.

Is this girl's little notebook really written on the method of cooking? It's not for people to see yet.

Zhang Yang said to her back: "I just want to see if what you wrote is correct." ”

Li Yue said: "I can write and understand. ”

Meals are served.

Li Yue ate with a bowl and said, "How do you say you can remember the days you have passed every day." ”

Zhang Yang's chopsticks paused, looking at her suspiciously.

Li Yue grinned, "I really want to remember every day." ”

Slowly put a stir-fry in your mouth, this season's dish tastes a little bitter.

Li Yue waited for a reply.

Zhang Yang said in a low voice: "You can write a diary." ”

"What is a diary?"

"A diary is a record of the days you live every day."

Li Yue nodded vigorously and said, "Yes, so that you can record the days you have passed every day." ”

Her mood was much better, as if she had found a new goal to strive for, and her eyes were full of energy.

Zhang Yang put a piece of fried meat into Li Yue's bowl, "If you look at the days you have recorded before after a few years, it will be a very interesting day." ”

"Hmm."

Li Yue smiled and nodded.

After the meal, Zhang Yang cleaned up the raisins at home, which were already ready to eat.

Zhang Yang tasted the taste, and it seemed to be a little too sweet.

There is no sugar in the soaking, which is the sweetness of the grapes.

Li Yue didn't know when she was already standing behind her, she stretched out her little head and stared at the raisins.

"It's ready to eat." Zhang Yang handed her some.

picked up a raisin, Li Yue put it in her mouth and tasted it carefully, and after eating one she put it in her mouth.

She squinted and said, "Sweet and salty." ”

Zhang Yang said: "You can eat some on weekdays, which will help your illness." ”

Li Yue put another one in his mouth.

Zhang Yang said again: "I haven't eaten too much, don't look at the sweetness, I sprinkled salt when I was sucking, and the salt content of this raisin is still quite high." ”

"Hmm."

Li Yue ate one after another, and it seemed that this girl was getting better and better the more she ate.

After eating the raisins in her hand, she sat back on the spinning wheel and knitted cloth and said, "The aunt next door said that the Tang Dynasty is going to war against Tuyuhun." ”

Zhang Yang, who was drawing the design drawing, thought that according to the original historical trajectory, the Tang Dynasty should not be so soon to start a war with Tuyuhun.

Li Yue said in a low voice: "However, we have General Li Jing in the Tang Dynasty, so don't be afraid of them." ”

Li Jing is really powerful.

Not to mention that Li Jing led his troops to the south to conquer a hundred battles, and now he has attacked the Turks in the north and captured Jieli Khan alive.

With such a splashing achievement, many people have seen the four very dazzling words in this feat, and the merit is high.

So much so that after returning to Chang'an after victory, Li Jing put down his military power and said that he was recuperating at home, living in a simple house, and he would not go to the court unless there was an absolute need, and he would not see any guests behind closed doors.

To the low is not really sick, who knows.

Li Shimin was also able to eat and drink with peace of mind in the Taiji Hall.

The Tang Dynasty monarchs and ministers are harmonious, which is reassuring.

In the quiet courtyard, Zhang Yang came to his stove again, put those small white stones into the stove, lit a fire and began to burn the stones.

Firing lime is a very time-consuming task.

Watching the flames burn, Zhang Yang covered the opening of the stove with a stone, trying to keep the temperature inside as high as possible.

Until night, Zhang Yang pulled out the burned stones from the stove.

Knock the burned stone open and put its powder into water, which is indeed a powder that is insoluble in water, and there are still a lot of impurities in it.

The heat is not enough, and the time to burn is not enough.

The next day, Zhang Yang was still decorating his house at home, repairing the walls of the house, and burning stones in the stove.

Li Yue didn't know why Zhang Yang burned these stones, but he just felt weird.

On the third day, Zhang Yang was still burning stones, and the progress of the decoration still could not be left behind, and the unstable bricks in the wall were replaced.

……

For more than ten days, Zhang Yang took the burned lime and put it into the water to look at the situation, and there were still impurities, but not much.

The burning temperature of the stove is not enough, and it is good to have this result.

Putting all the burned lime into a dry jar is also a very good building material.

Taking a bag of lime and a pot of soy sauce, Zhang Yang said to Li Yue, who was chatting with the two aunts, "I'll go out." ”

Li Yue said: "Well, I want to eat braised pork at night." ”

"Okay."

Zhang Yang walked out the door with his things.

Li Tai has been by the river for the past few days.

The moment he saw Zhang Yang, Li Tai had tears of excitement in his eyes, "After waiting for so many days, I thought you wouldn't come." ”

A wagon came with a large pile of things, piled with timber and some nails, and sand.

Li Tai said: "I have brought everything you want, can I make soap?" ”

Zhang Yang took out another roll of bamboo slips and said, "Your Royal Highness King Wei, this is the method and ingredients for making soap, and I have written it in detail." ”

Li Tai looked at the content on the bamboo slip and unconsciously read it, "Animal fat, plant ash, special stone powder......"

In fact, the method of soap is simple and simple, and the most important thing is the extraction of alkaline substances.

Zhang Yang handed him a bag of white powder and said, "This is a special stone powder." ”

Li Tai looked at the method written on it with a sad face, "Just looking at the manufacturing method on it, I don't know what kind of soap is made." ”

For the sake of Li Tai's face as the largest shareholder......

Zhang Yang still showed him how to make soap first.

In the past, when I lived alone, I also made soap, mainly to save money.

Things that can be solved with technology are a bit wasteful to spend more or less money.

Although in the previous life, he was said to be slamming the door every day.

Li Tai said to the two uncles behind him: "Two uncles, please take care of it, this is a business that can earn tens of thousands of dollars a year." ”

The two uncles nodded, staring at Zhang Yang's approach.

The main ingredient of soap is a mixture of alkali and oil, and the production of lime is not going to be handed over to Li Tai for the time being.

Everyone partners in business, in this era when the status class is not equal to everyone, if the prince pays the bills, he really has no good way as a commoner, he can only admit losses.

Be a good man.

Keep a hand in everything.

The most critical thing still can't be handed over to Li Tai.

The boiled and mixed grease is put into a wooden box mold and waited for it to cool and slowly solidify.

Li Tai looked at the whole process and said, "It doesn't seem to be very difficult. ”

After a while, Zhang Yang took the solidified soap out of the wooden box and handed it to Li Tai.

Li Tai took the jade-like soap, which was yellow, and sniffed it carefully.

Zhang Yang said: "His Royal Highness King Wei, not everything that has been cooked can be eaten. ”

“……”

Li Tai snorted coldly: "Eat this? Are you really stupid? ”

Observing the soap, Li Tai continued: "This thing is fragrant. ”

"Because I added mint."

"Mint?"

"If His Royal Highness King Wei wants other flavors, you can add some other things to the soap, such as chrysanthemums or something, and there will be a chrysanthemum smell when you make it, and after taking a bath with this, there will still be a lingering fragrance on your body."

"In this regard, His Royal Highness King Wei can give full play to your imagination when it comes to adding things to soap."

Li Tai washed his hands with soap, and after washing, there was a faint mint smell on his hands, and he liked soap more and more.

After putting away the soap again, Li Tai looked back at his two uncles and said, "Have you written down the two uncles?" ”

"Got it."

Hearing the response of the two, Li Tai said again: "If this secret recipe is leaked......

The two of them bowed down and said, "Raise your head and see you." ”

Li Tai smiled and said, "How much silver do you think this thing sells for?" ”

Zhang Yang said: "Why don't you pay ten pennies a piece?" The cost is also not very high. ”

Li Tai's chubby face was a little more sinister, "Ten cents? This king wants to sell it for a piece of money, and the magnates of Chang'an City are rich. ”

Zhang Yang pulled Li Tai and whispered, "His Royal Highness King Wei, shouldn't we discuss it and divide the dirt...... No, the matter of dividing money? ”

Li Tai smiled and said: "That's nature, how to divide this money?" ”

Zhang Yang said: "Without me, His Royal Highness King Wei would not know what soap is, nor will he know the use of soap, nor will he know how to make soap, yes or no?" ”

Li Tai nodded.

"And the special stone powder is only available to me, which is also the core formula of our business, yes or no?"

Li Tai still nodded.

Zhang Yang said again: "Originally, I planned to open seventy-three, I took seventy percent, and His Royal Highness the King of Wei took thirty percent, but in the future, the construction and operation of the workshop will be done by His Royal Highness the King of Wei, I can take a step back, how about June Fourth?" I take sixty percent, and His Royal Highness King Wei forty percent. ”

Looking at Zhang Yang's expression, Li Tai said: "This king understands that this special stone powder is only available to you?" ”

Zhang Yang nodded, "For the time being, only I have it." ”

Li Tai said again: "You can't make soap without this stone powder, okay, your surname is Zhang, have you already calculated it, and without the secret recipe, there is no room for negotiation at all, right?" ”

"His Royal Highness King Wei, I can't say that, I'm not taking a step back and letting Yicheng profit you."

Seeing that the little fat man looked reluctant, Zhang Yang said again: "If the business is good enough in the future, we can talk about it again in the future, and the opening of June Fourth is just an expedient measure, and I will give all the secret recipes to His Royal Highness King Wei at that time." ”

Li Tai's frowning brows relaxed a little, "In that case, let's do this for now." ”

Zhang Yang clapped his hands and said, "Very good, make a note!" ”

Li Tai was surprised: "What kind of note?" ”

Zhang Yang said: "Of course, you have to set up a written note, otherwise what should I do if I repay the debt?" ”

"Will this king pay his debts?"

"White and black characters, the words are based on the drawing, and whoever defaults on the account will see you in court."

……

The two finally made a note by the river under the witness of their two uncles.

The moment Li Tai signed the signature, he felt an inexplicable humiliation.

I am the dignified King of Wei, and I actually want to make a note with someone.

As the king, will he still be able to repay his debts?

After the painting was finished, Li Tai had the urge to tear up the note, which was too humiliating.

The contract is to be made in duplicate, and one copy is taken after the drawing.

Zhang Yang took the contract and said, "If there is nothing to do, I will go back first." In the future, we should try to move around as little as possible. ”

"Why?"

"Because every time I see His Royal Highness King Wei at such a young age full of calculations, I want to strangle you."

“……”

Li Tai pointed to the things on the carriage and said, "Aren't these woods, iron nails, and stones used for soap?" ”

"Of course not."

"And you're going to..."

Zhang Yang got into the carriage and said, "When did I say that these things are used to make soap." ”

"You ......"

Li Tai stood in place, watching Zhang Yang drive the carriage away and drift away......

Zhang Yang drove the carriage to the door of the store outside Lantian County, and there were still some customers eating in the store.

Ding Yu saw Zhang Yang coming, and hurriedly greeted: "Brother Zhang, you have finally come to the store." ”

Zhang Yang handed him a pot of soy sauce and said, "The soy sauce in the store is running out." ”

"As Brother Zhang expected, it is indeed running out." Ding Yu's face was full of smiles, since the store made money, he fell asleep with a smile, and after being poor for so many years, he could finally earn enough money to marry his daughter-in-law.
