Approaching the end of the year, although there was no need to hold a banquet, Shen Qiutan still couldn't go easily.

She has to take accounts, she doesn't run many shops by herself, but then Li Jingsai gave her a lot of them, it turned out that she was able to get by, and after getting married, she became more and more less motivated to make money, and she felt that she could spend enough, but now her husband wants to raise soldiers, her son grows up to marry a daughter-in-law, and her daughter wants a dowry. Everything costs money.

After calculating it one by one, she felt that how much money was not much!

As a result, she is full of energy every day, and has rediscovered the joy of making money.

Li Chen's busyness is different from her, he is busy improving weapons with craftsmen, and busy calculating time and labor costs. From pig iron to 100 steel, there are many processes, and not everyone has the technology to meet the standard, but weapons are in short supply.

This is a technical problem, Li Qian finally got the iron ore, but he is still a little at a loss.

Shen Qiutan turned over and found that her husband was not asleep, she muttered: "Don't think about it, sleep, I'll talk about it tomorrow." ”

"Hmm." Li Qian patted Shen Qiutan's shoulder, still unable to sleep.

It's the year soon, and it's also the first birthday of chubby and strong.

Li Qi felt that it didn't matter if it was the year or not, whether there was a banquet or not, he himself had been pressed for more than 20 years, and the only thing he didn't mind was that he had wronged his two children.

There is only one time when he is a year old, but Jingzhong is so closely watched, it is impossible to do it with great fanfare.

Shen Qiutan is okay, she thinks that being together as a family is more important than anything else, and there is nothing wrong with being bland.

After arranging the things for the year and the things for the two children in advance, Shen Qiutan found that Li Qian was still a little worried.

"What the hell is going on? Say it and let's figure it out together? Shen Qiutan has been studying baby food recently, and she often puts a lot of things into a manual blender to stir them, the colors are strange, and the children don't like to eat them, but she eats them with relish.

At this moment, she was holding a plate of light turquoise ...... The steamed cake like a caterpillar, seeing that Li Qian should not, directly picked up a caterpillar and bit off the head of the worm.

Li Xuan: "......"

Red bean paste was exposed inside the insects, and Li Qi was helpless: "Qiu Tan, what are you eating?" ”

"Ah, it's not that your son is a picky eater, he finally squeezed the endive juice, he doesn't like it, I think it's not good to waste it, so I have to make bean paste buns with noodles." Don't look strong and fat, but there are requirements for eating, but Shen Qiutan thinks that he can't eat caterpillar bread, and it's not bad to eat a caterpillar red bean bun.

Thinking of this, she said, "Let's make an oven!" I draw drawings. ”

Nowadays, there are ovens and ovens, but most of them are grilled meat, so it is not suitable to bake some bread or something.

Li Xuan suddenly said: "Qiu Tan, where did you learn this drawing ability?" The distillation machine you got before and the drawings that came to me later......"

"Yes, of course...... I saw it in miscellaneous books. For some reason, Shen Qiutan can even tell Li Qian about her transformation, but when it comes to crossing things, she always feels a little difficult to talk about, and she subconsciously wants to hide a little secret.

"Where did the miscellaneous books come from? Can you lend me a look? "Maybe there is something unexpected in the miscellaneous books that my wife reads.

However, Shen Qiutan shook his head: "On my father's bookcase, all the fires were burned back then. ”

Li Qian was silent and said for a long time: "Well, it's all over." ”

"However, you can tell me, I don't understand your big things, but maybe I can really give some advice on small things." Shen Qiutan was reluctant to let Li Xuan be distressed.

The fairy in purple said she couldn't change it, but she had changed many things unconsciously.

And the words of the fairy in purple may mean something else, not that she is not allowed to change the current era with what she has learned in modern times, but that she is not allowed to abuse pepper to change the physique of others.

The times are always progressive, and even if there is a change of dynasties, it always follows the trajectory of history, but changing people's physique is another matter entirely.

So thinking about it should be fine.

Li Xuan told Shen Qiutan about the steelmaking method that had been troubled for a long time, and he actually threw out the question of how to increase the efficiency of forging weapons.

Shen Qiutan thought about it, didn't speak for a long time, and after thinking about it, he finished eating a plate of green bean paste buns.

She wiped her mouth: "Have you heard of the steel filling method?" ”

Li Qian frowned.

Shen Qiutan said: "The hundred refining steel we use now is handed down from the Wei and Jin dynasties, although after thousands of tempering, the effect of forging weapons is quite prestigious, but after a hundred tempering, it has to be repeatedly heated and forged, and the manpower and material resources consumed by thousands of tempers are huge. ”

Li Qian listened solemnly, and Shen Qiutan said slowly: "The reason why it has been tempered is to remove impurities, and at the same time to enhance its steel hardness, so that it can become the standard for weapons or other utensils. I've read in a book before that if you use the steel filling method, you can almost omit the step of tempering and removing impurities. ”

To put it bluntly, the steel filling process is to pour molten pig iron with high carbon content into red-hot wrought iron with low carbon content, melt and mix with each other, and directly obtain rigid steel, that is, the so-called high-carbon steel in modern steel technology.

Li Qi's eyes lit up when he heard this: "Qiu Tan, you wait, you go to the study with me, and I'll pull a few more people!" ”

After a while, there were five or six people in the study who Shen Qiutan didn't know.

Li Qi introduced: "This is the princess of this king, the Shen family. He said to Shen Qiutan again: "These are all experts in forging weapons that I invited. ”

Everyone saw each other, and was very surprised that King Qi brought the princess over, and heard that this lady had just entered the door and gave birth to a pair of pleasing dragon and phoenix fetuses, which was very favored by King Qi.

Although they are all born in iron, they are not high, but they still have a bit of status.

Shen Qiutan didn't know where Li Qian found such a group of people, and she didn't pay attention to their contempt, she was for Li Qi and not for these people.

"I heard that the princess has a method of improving the forging of 100 steels?" One of them, a middle-aged man with a dark face, asked.

Shen Qiutan nodded, and calmly explained the process of the steel filling method to everyone present.

"Niangniang is true, can she still do this?"

Shen Qiutan smiled: "Why can't you do this?" Besides, whether it can be achieved or not depends on the truth in practice. What do you think? ”

Li Qi was next to Shen Qiutan, looking at Shen Qiutan with a smile and talking eloquently.

The middle-aged man who asked at the beginning couldn't help but say: "Your Highness, please allow your subordinates to enter the mountain after the New Year, your subordinates can't wait to try new methods." ”

"The subordinates will go too."

Here's a chorus of echoes.

King Qi is heavy on fortifications, which is the reason why they follow King Qi, but also because they are a little obsessed with various skills and crafts.

Li Qian nodded in agreement and exchanged glances with Shen Qiutan.
