Lou Ning has always liked smart children.

Seeing Ma Yao and the others drawing inferences from one example and finding the core target so quickly, they immediately burst into laughter.

"Yes, I hope this item can be made for your eldest brother and the others to wear. If possible, it will be able to reduce the battle losses of our soldiers in the Oyue Kingdom, so that more families will not lose their main support."

Battle losses in ancient times were sometimes more terrifying than those in the interstellar world.

Because of the destructiveness of wounds and the lack of medical technology, many people often die because they cannot be treated, or they are infected after being injured, and they cannot get effective treatment, so they die in pain.

Lou Ning is limited by system settings and cannot change their development process too early.

But if we reduce their risk of injury from a defensive perspective, this is still within an acceptable range.

"It's so awesome..." Everyone always has a natural awe for powerful things.

Especially because the things Lianchun brought out were always the most useful, so the children not only did not doubt what their sister-in-law said, but they also excitedly passed around the 'metal cloth piece' that was no bigger than a palm.

"It doesn't feel very easy to make." Ma Wei was more stable and mature. After reading the thing, he turned around and asked seriously, "Besides, it must have cost a lot of money, right?"

Lou Ning is very open about this. Although as an adult, you have to take care of everything at home, the main thing is to let the children have a good quality of life.

But if they asked, she would never hide it.

"That's right, this thing costs about fifty taels of gold." Lou Ning also had a headache - because the smelting technology of Dayue Kingdom was not good enough, and the ability to refine metals and make alloys had not been developed either.

So from the beginning to now, she has been trying very hard. It took more than a year of hard work and a lot of waste of purchased materials to come up with something like this.

"Wow!" Ma Yao and Ma Pei still know that their weekly pocket money is five cents, especially if they save five cents before, they can also add meat for themselves every month...Looking at it

The entire Jingcun is extremely wealthy.

And fifty taels of gold?

How many should there be?

"This thing feels so difficult!" Ma Yao looked at the things in his sister-in-law's hands silently. He only felt that he had difficulty breathing and his heartbeat was strangely erratic. "Sister-in-law does it by herself... I won't feel it."

..."Can't you do it?

As if she could hear her own question, the expression on the sister-in-law's face was still gentle, but it also became serious.

"It's very difficult. If it weren't for reading so many books in your elder brother's study, I wouldn't have been able to achieve this result so quickly."

She looked at the dumbfounded child and knew not to make a simple truth too difficult.

"Because this piece is an experimental product, it must be made rigorously at the beginning. Therefore, in addition to the high cost, the sister-in-law also has to spend time learning forging, and learn from the blacksmith uncle how to forge, purify the metal, and make things become

It has to be durable.”

"In addition to making things durable, we also need to find ways to make things elastic, flexible and connected. Especially because we have to repeatedly make one piece of things, how do we make each piece look the same and become

Quite a crucial thing.”

Several children looked up at their sister-in-law stupidly.

They just think that every word should be understood.

But after putting it all together, it's all a bit foggy.

This shouldn't be the case.

"So, if we don't know enough, not only will we not be able to help my sister-in-law, but we may also be of no help." Ma Wei is indeed the one with the most solid response among the children, and the one who best emulates Lou Ning's true legacy.

"I will study hard. In addition to the homework assigned by the master, I will also read the books in my elder brother's study!" The child made a serious face, and then said very seriously, "It must be very hard for my elder sister-in-law to study alone. I want to

I wish I could help you sooner!"

"I, I want it too!" As an 'elder brother', Ma Yao has always been unwilling to let Ma Wei be the preeminent one.

When I heard what he said, although I didn't quite understand it yet, I was still very excited and said loudly, with my belly puffed out,

"I-I can learn!"

Wuwuwu... The homework assigned by the master is really too difficult. If you have to memorize those things, I might not even know what it feels like to play outside!

"Ma Pei wants to learn too!" Ma Pei saw that her two brothers were getting involved in the work of the sister-in-law. She knew that there was nothing in Ma's family that the girl's family could not learn together, so she immediately raised her hands and was quite enthusiastic.

Said, "Ma Pei also wants to help my sister-in-law!"

Lou Ning looked at the positive looks of the little carrot heads and felt greatly relieved.

"Okay!" I finally got a few kids to actively encourage me. Although it is really impossible for them to help in a short time, it can at least give them some motivation to learn, so as not to accidentally end up having fun.

Of course she didn't let the children play.

But since we have grown up slowly, we naturally have some corresponding responsibilities that we must bear.

"But it's very hard to learn this. You have to finish the homework assigned by the Master before you come back. You can't put the cart before the horse." She then said to the younger ones, "This thing is a gift for your eldest brother, so wait until we do it together.

Give it to him after you finish...Before this, we all agreed not to tell him, do you understand?"

Over the years, everyone has been influenced by Lian Chun's habits to some extent. They know that birthdays should be celebrated and gifts should be given, and it would be great if there are surprises.

So when the elder sister-in-law said this, no one was suspicious. Instead, they nodded happily and responded loudly.

"In that case, let's start memorizing the writing homework first." Lou Ning turned in such a big circle, naturally for this ultimate goal.

After reading for a few hours, Lou Ning left his study and walked outside.

"Sister-in-law?" Because of her age, Ma Fang is also studying, but she still has memories of the year before. In addition, the Ma family has made rumors that they will keep her for a few more years, so she is not married yet.

But her virtuousness and ability have indeed caught the attention of interested people. In addition, she is always taken by her sister-in-law when going out and going out. She has reached a level that is difficult for ordinary people to reach, so this year there are still people coming to her to ask for marriage.

The eldest brother and sister-in-law did not force her to get married, but they also said that she could take her time and see what she likes.

Especially my sister-in-law, she even suggested that she can slowly prepare her favorite wedding dress, etc., whether it is for practicing or something else, it is always a kind of leisure.

So she spent her free time learning how to embroider wedding dresses from her mother-in-law.

"Are you still used to it?" Lou Ning has no problem learning by himself, but it's really difficult to mend clothes or embroider. Every time he sees Ma Fang and Qian making female celebrities, he feels overwhelmed, "If there is anything missing,
