Queen Mother is a Scientist

Hua Qingxue's dorayaki and crispy egg rolls were a great success.

With popcorn as a signboard, regular customers are very concerned about her newly-made dim sum. Although the price is more expensive than popcorn, but every year during the holiday, everyone does not care about this article and two articles.

The nearby stall owner persuaded Hua Qingxue that since it was easy to sell, he would make more to sell tomorrow.

Hua Qingxue just smiled, but did not plan to do much.

The current amount is calculated by her and is within the tolerance range.

Although she is anxious to make money, she doesn't want to make herself too tired. At present, it is already very hard to make dim sum early every day. If the amount is increased, she will be really tired.

If the body is exhausted, it is worthless.

When it was time to close the booth, He Wu came, and the tall man stood in front of the tea stall in a hurry, and said bluntly, "My mother said, afraid that the Li family would come to trouble you, let me come and take the hand."

Hua Qingxue suddenly realized, then nodded, "Ah... Then, thank you, Brother He."

Hearing her calling him Brother He, He Wu's face gradually became red again.

He sullenly picked up the bench table and chairs, and helped Hua Qingxue pile up the odds and ends on the scooter. Before Hua Qingxue said more, he pulled the scooter and left.

A good-sounding laughter came from the stall next to him, He Wu's steps could not help but hurry, the cricket was turned upside down, and even the wooden barrel and wooden bench above were shaken violently. Objects.

The two of them walked back and forth one after the other, and there was really an embarrassment for both husband and wife to return home...

Hua Qingxue walked and thought, the house here can't be rented anymore, although Aunt He is very good to her... But staying there, inexplicably has a sense of both his daughter-in-law's sense, it is too embarrassing.

This feels really not wonderful.

Wait a few years...

I will make a few more months of money after the year, and I will be able to rent a house in a separate house if I have enough money.

When I got home, I watched Aunt He from the distance standing at the gate of the courtyard, beckoning at them, and pulling a chicken in the other hand.

"Wu Zi! Help me kill the chicken. I'll make you your favorite sauce-roasted chicken today... Oh, by the way, chopping the pork stick bones in the kitchen to make soup."

He Wu pulled the rickshaw into the house without a break, and took the chicken from his mother's hand and sharpened it.

Aunt He helped Hua Qingxue unload the things on the scooter and waved to catch her, "Go and rest, drink some hot water to warm your body, it's freezing this day... Come out to eat later, try aunt Craftsmanship."

Hua Qingxue smiled a little embarrassed, because she came back late every time, so she would rub the food of Auntie He's home from time to time.

In fact, she knew it was not good, but she couldn't withstand the enthusiasm of others every time...

It’s always bad to eat white rice, and Hua Qingxue also wants to do some work, saying, “I’ll help Brother He chops ribs.”

Although she won't kill the chicken, it's OK to chop the ribs.

"Why can't you do this with Jiao Didi? This kind of energy will work for Wuzi!" Aunt He refused, and turned to the kitchen to cook.

Auntie He's cooking style is quite chef-like, which makes Hua Qingxue think that the auntie Yan once knew in Renqiu, a large iron pan can be beaten for ten times with one hand, and he must continue to stir fry.

She can't hold a pot so heavy with one hand, let alone pick it up.

Hua Qingxue had nothing to do with it, so he boiled the water in another pot. He Wu could kill the chicken after he killed it.

As soon as the water was ready, I heard the sound of ping pong in the courtyard.

Hua Qingxue was shocked and hurried to the yard. He saw that He Wu had already killed the chicken. Now he was wielding a knife at a pile of pig bat bones!

"Brother Ho, don't you..."

It's too late.

He Wu stopped his hand, raised his long knife, and found that a gap had been broken, as if it was missing an incisor. It was ugly, and the other places where the blade was cut were also crooked.

Hua Qingxue discovered that He Wu used his sword in the barracks.

He Wu looked at the broken knife in his hand and frowned.

"Ah... this knife is broken, doesn't it matter? Will it not be dealt with by military regulations?" Hua Qingxue asked him worriedly.

He Wu looked a little shy in front of Hua Qingxue, he grinned: "It's okay, the barracks of the barracks are often broken. I've been used to it for a long time, and I can use it after repairing it."

Hua Qingxue glanced at the still strong pig bones on the chopping board, a bit embarrassed, and whispered: "I re-cut a new set of knives from Liu Tiesmith, there are special tools for cutting bones... I will get it for you use."

He Wu nodded.

When Hua Qingxue came back, he really had a brand new knife in his hand.

He Wu looked at the knife and felt that the streamer across the edge of the blade was very eye-catching. He held it in his hand and felt very good.

"This kitchen knife is really good." He Wu couldn't help but praise.

Hua Qingxue smiled and said, "It's not a kitchen knife, it's a bone chopping knife. The original knife is not easy to use... I have a new set of slicing knife, bone chopping knife, boning knife, peeling knife, vegetable knife. ..."

Don't look at her cooking skills, but these tools are very proficient.

Hua Qingxue has always believed that no matter what you do, preparing a set of tools can improve efficiency and delight your body and mind.

For example, she feels that, since she had this set of knives, her cooking skills have grown substantially like in Renqiucheng.

"The Chinese girl is so delicate, even the kitchen knife is so finely divided."

He Wu hey smiled, began to cut bones with the knife-

Snapped!

The bone on the chopping board broke into two sections at once.

He Wu couldn't help but stunned, he was very surprised!

This sense of heavy blow, this sharpness, is better than any knife he has ever used in a military camp!

He Wu couldn't help but pick up the knife again, and looked carefully.

But no matter what he thinks, it is just an ordinary kitchen knife, why?

"Liu Tiejiang's craftsmanship is getting better and better!" He Wu naturally does not think of Hua Qingxue. He praised again, and began to crack his bones in his hand.

He was originally worried that he would cut the new kitchen knife, but the more the kitchen knife was used, the more smooth it was!Until the bones were completely chopped, He Wu still had some intentions, so he took the chicken that he just killed to pluck and rinse it, and then cut it into pieces!

After the chicken was cut, He Wu simply took a knife and made a majestic gesture in the yard—

When Aunt He came out, he saw his son practicing in the yard, mumbling two words: "What is this crazy, waving with a kitchen knife, carefully splitting the clothes rail in my yard..."

Hua Qingxue stood aside and snickered, and she knew vaguely why He Wu did this.

This is also very strange to say. Although the Daqi Dynasty was similar to the Song Dynasty, the metal smelting technology was very backward, far less developed than in the ancient Song Dynasty.

And many metals that are well-known in modern times are actually not mined here or even unknown.

Hua Qingxue discovered on the first day of cooking that the kitchen knife was very difficult to use. Even if it was sharply sharpened, he could only cut some vegetables and meat, but the harder one would not work. There will be redness everywhere.

-This is because the carbon content in the knife is too high.

Originally, iron was a very soft metal that could neither be made into a knife nor cast into a pot, but when the iron contained a certain amount of carbon, it became the iron commonly used in daily life, so-called Steel.

The higher the carbon content, the higher the hardness of iron. Conversely, the lower the carbon content, the lower the hardness of iron.

However, the iron is not the higher the hardness, the better, pure hardness, but the easier it is to chip and break.Just like He Wuyong's military sword just now, although it is sharp, it will be damaged once it encounters hard objects.

Therefore, the carbon ratio is very delicate, but for Hua Qingxue, it is very familiar.

Her major is in the direction of new thermal weapons. She once studied courses on the history of ancient cold weapons. The metal forging process is just as familiar as the old one.

In ancient times, the best way was to use folding forging, striking steel and wrought iron closely layer by layer, and using the carburizing method. The resulting knife was not only sharp, but also had a certain toughness. It can be called a fine product in the knife, and other blades are in contact with it, and few are not damaged!

Hua Qingxue also forged in her classwork exercises, but at that time there were various modern advanced instruments, and she only needed to check all the values.

In ancient times, this kind of forging work required a lot of effort, so this set of kitchen knives was forged by Liu Tiejiang under the guidance of Hua Qingxue.

Although there is still some distance from the ideal state in Hua Qingxue's mind, it is certainly a matter of course to cut a rib or something.

Hua Qingxue saw that He Wu was doing everything in the yard. He thought, since he likes it so much, he might as well give him a hand. Anyway, his military sword can't be used for the time being.

But this kitchen knife dances a little bit...

Hua Qingxue turned and entered the kitchen again, and took out a sharp pig-killing knife.

The shape of the pig-killing knife is very similar to He Wu's military saber, but it is shorter.

"Brother Ho, you use this."

He Wu heard Hua Qingxue's voice, stopped, and saw the pig-killing knife in her hand, his face immediately filled with joy.

Although he knew that it was inappropriate for him to take things, he really liked the knife so much, and immediately said nothing about holding the knife in his hand.

The knife handle is in a streamlined arc, which fits exactly with the palm of the hand. The blade is light-weight and not tired for a long time. The blade is sharp and sharp, and there is a long groove on the back of the knife.

"Why did Liu Tiejiang make a groove in this place?" He Wu asked strangely.

Hua Qingxue explained: "This is called a blood trough, which can increase the strength of the knife, reduce the weight of the knife, and also increase the injured area."

He Wudanghua Qingxue was heard from Liu Tiejiang. Without much thought, he held the pig-killing knife in his hand and played a few times. He smiled and said, "Well, it's really lighter."

There is a saying that it is hard to buy a lot of money. He Wu took Hua Qingxue's knife, took out a purse from his arms, and handed it to Hua Qingxue. "Hua girl, I don't know how to thank you, these money You take it..."

Hua Qingxue was taken aback and waved his hand again and again, "I live here and rubbing and eating and drinking has been very disappointing, this knife is not worth a few dollars, you don't have to worry about it!"

She finished, afraid that He Wu would charge her money again, and fled into the kitchen.

He Wu stood in the courtyard, holding a pig-killing knife in his hand, and felt sweet in his heart...
