"How do you know? Did you eavesdrop? Yan Lao Er asked nervously.

Yan Yu is speechless, is she the kind of person who has no taste.

Can there be more basic trust between dad and daughter?

She pointed to her little head.

"It's all here, I saw Second Uncle Hu helping to mix a white powder just now, and I remembered it immediately."

The formula of soil cement, which has only a few raw materials, is really easy to remember.

Of course, it's not enough to remember the ingredients, the most important thing is the proportions.

Yan Yu didn't know how good Master Lu's recipe was, but what she knew was the result of countless people's improvements and summaries.

It is also the common choice of many web authors.

"Master Lu should use clay, quicklime and gypsum."

She secretly motioned for her father to look.

Yan Lao Er pretended to look at it inadvertently.

There should be no doubt about the clay, or the boys in their village helped pull it back.

The lime could also be seen, only the plaster, which he couldn't distinguish.

"How do you know it's plaster?" Yan Lao Er asked curiously.

Yan Yu smiled like a little fox, "I don't know, Cui Langzhong knows, gypsum is also a kind of medicinal material, I rubbed it in the past and asked him to help me identify it." ”

Yan Lao Er was convinced.

"It's as simple as that? Then why is Master Lu still so strict and practical, don't you know if you pay more attention to it? ”

Yan Yu said: "My father, of course it's not that simple, the proportion is very important, and I suspect that Master Lu will add something." ”

"Tim what?"

Yan Yu thought for a while and said: "I have seen people say that the strength of this kind of soil cement is still very sufficient, but the frost resistance is poor, and the solidification is slow. ”

A flash of inspiration flashed in her mind, and she said: "Dad, this is Guanzhou, a border city, the stucco recipe for building the city wall is the best, I remember that in ancient times, glutinous rice was used to boil and stir sand, which was very strong, etc., let me think about it, brown sugar, elm bark, camphor camphor sap, hahaha, yes, that's it!" ”

Yan Yu is not proud of himself, look at our memory, and ask, who else!

If it weren't for the wrong occasion, Yan Lao Er would have wanted to lift his daughter high.

That's awesome!

Better than the Three Treasures!

He thought of the geothermal project that had been devastated by Waterloo.

asked his daughter: "Dabao, you say, is our geothermal energy spectrum?" ”

Yan Yu looked at her father indescribably.

"Daddy! Let's be realistic, geothermal heat should not appear in the homes of small people like us, you inquire, the prince of the fiefdom of Guanzhou, the British royal family may not be able to enjoy this blessing. ”

She wrinkled her little face and said bitterly: "How can we be Dad!" ”

Yan Lao Er:

"The wall of fire is very good, and even the fire kang is beautiful." Yan Yu thought that he was about to roll on the fire, and he didn't look forward to frying on both sides.

"Is your recipe better or Master Lu's recipe?" Yan Lao Er asked.

"Of course it's me." Yan Yu replied.

"Then what are we going to do and replace his plaster?" There are good ones, of course, I want to use them in my own house.

Yan Yu only said one sentence and dispelled Yan Laoer's thoughts.

"Glutinous rice boiling, brown sugar daddy, that's not a binder, it's all money!"

Yan Lao Er thought so, and the happy decision of the father and daughter remained the same.

"If you don't get rid of these two, we can try the rest." Yan Yu was ready to do a big job.

"Soil cement, the use is too big, if it can be restored, no, enough for us to use, the house is built, we still have the courtyard wall, the house has a stone floor, and the yard can be plastered with cement leveling.

Oh, and toilets! Dad, let's not worry about the heat, the toilet is the point! ”

The importance of squatting in the pit was realized as soon as they walked through.

As soon as he mentioned the toilet, Yan Yu said again: "There is also our self-produced fertilizer to build a cement pool for them, Dad, the soil pit you dug is too shallow, let's learn from experience and dig it deeper next time." ”

Yan Lao Er:

also said that he was entangled, at least the things he was entangled in didn't stink, and his daughter actually pondered these stinky things.

Yan Yu knocked on his skull in frustration.

It's a pity that this brain is not completely useful, and I can't remember a lot of things.

For example, glass, winemaking is a miracle skill to make a fortune!

Yan Lao Er didn't have time to pull his daughter down anymore, so he rushed to the field by the river.

When I got to the ground, I couldn't help but sigh: Mama Rong is really a top two!

The weeds are all neatly piled up.

All he had to do was light the fire.

The matter of burning grass must be treated carefully, especially in places where grass and trees are luxuriant.

Yan Lao Er called a few aunts of the Song family for help nearby.

The old Song family is also prosperous, but it is the opposite of the Luo village chief's family, Wang daughter.

The old man Song and the old lady Song have the ability, the girl is good-looking and capable, and the son-in-law is unique, let's not talk about getting rich, but after the young couple got married, they got our old Song family to live, if they agreed, they didn't want any bride price.

Just not wanting a bride price makes people in ten miles and eight villages rush to it.

If you don't change your surname, you still eat the rice and grain of the old Song family, and there are too many people who are willing.

No, the three daughters earned back the three aunts.

The fourth boy of the Song family was originally a lone seedling with a weak body, but since welcoming the three brothers-in-law, not to mention the hard bones, he also brought an old child to the Song family.

The fifth child of the Song family is one year younger than his daughter.

What is it called? It's called wisdom!

Collected the three aunts, what is the difference between it and Bai Xuan's son!

Yan Lao Er felt that he had to learn from others.

Enrich your own experience.

Light a small fire first, and then rake and rake the grass up, and you can't be in a hurry.

The fire raged quickly, and the flames flew high.

There is no wind today, and it is really a good weather to burn grass.

The four men kept the fire under control at all times.

The grass hadn't dried yet, and smoke was billowing in.

Yan Lao Er ran away a little longer to catch his breath, and quickly ran back.

Masks, masks!

Oh my God, he's missing the mask so much right now!

He didn't know how to cherish it when he wore it every day, and he didn't regret it until he didn't have it.

The pain of being choked, who chokes who knows.

If he is given another chance to re-burn the grass.

He'll definitely make a mask first!

The Song family's aunt burned the gray face and went home for lunch.

Yan Lao Er thanked him.

The third aunt of the Song family is quite happy.

"Second Brother Yan, you burn grass again to greet me."

Yan Lao Er:

It's also fun.

Back at his homestead, Master Lu was leading people to sift clay.

Sifted several clay into a fine surface, and stirred with quicklime and gypsum in a certain proportion.

Pour water and mud.

And then

Master Lu really poured water from two bamboo tubes into it as his daughter said.

Yan Lao Er approached curiously and moved his nose.

Sweet and silky taste.

It's brown sugar.

At this moment, Yan Lao Er felt relieved.

Master Lu's craftsmanship, his construction team, bless the cost of brown sugar.

There was a feeling of great value for money.
