The cannon fodder daughter was exiled, she has a system to earn gold

"Sure.

They are all freshly soaked and eaten.”

At this time, Qin Zhongyue made a bowl of instant noodles and brought it out.

"Third brother, you've been busy all morning and haven't eaten yet. Have a bite to fill your stomach."

"Okay, thank you, sister."

Qin Sanshou actually picked up a big chopstick and started eating noodles in front of the middle-aged man.

"Dad, buy it for me!"

The little boy was the first one who couldn't hold back his saliva and shouted to his dad to buy it quickly.

"What flavor are you eating? Give me six packs."

Before the middle-aged man could say anything, a man dressed as a student behind him spoke up and took out a dime.

The price of instant noodles is written on the counter. People who can read will know it at a glance, and those who can’t read will also ask.

The waiter Wuyoumang cleverly brought the instant noodles, counted and packed them in front of the customer, collected the money and handed it over with both hands.

Because the advertisement at the door was good, Qin Sanshou was also advertising inside the shop, and instantly people who loved to eat it couldn't resist it anymore, and they all took out their wallets and bought at least two packs.

"Daddy!!"

The little boy was so anxious that he was afraid that the instant noodles would be sold out. The middle-aged man didn't hesitate any longer and shouted, "One pack of each!"

Chengpi, the new servant beside Qin Erlu, found Qin Zhongyue and reported in a low voice.

"Miss, the Second Master said that if you are free, please come home. He has something urgent to tell you."

This orange peel was picked out by Qin Erlu, a servant who ran errands for many of them, a few days ago. He was quite smart.

"Did the second brother go home or to the palace?"

"The Second Master is in the Qin Mansion."

"Sister, please go back soon. We are busy here."

When Qin Sanshou saw that it was Chengpi who came, he knew that his second brother must have something to do with his sister.

Qin Zhongyue nodded and walked out of the back door as there were too many people in the shop in front.

When I arrived at Qin's house, I found Xiao Jingyi was also there.

"Come and sit here, sister."

"What do you want from me, brother?"

It must be something important that the second brother asked Chengpi to find her.

"I just want to ask who made this thermos bottle for you, and if you can introduce that person to me.

This kettle is very useful. I want all the soldiers to use it.

If you bring a few packs of instant noodles and a bottle of water when you are on a mission outside, you can solve the problem of food and grass, which is very useful in many cases. "

Xiao Jingyi nodded and agreed with Qin Erlu's point of view.

He didn't know the use of this thermos bottle at first and was reluctant to use it. It was Qin Erlu who found him and told him the reason, and then they went to find Qin Zhongyue together.

Qin Zhongyue felt that this matter was a bit difficult to handle.

Because this is not made by the people here, and I don’t know if the people here can make it.

Speaking of this thermos, it was a ceramic thermos that she asked Niu Su to find specifically for her fourth brother who would take an exam in nine days.

It was for emergency use. In case it rained and we encountered bad luck and couldn't make a fire ourselves and had no hot water, we asked Niu Su to get it.

Niu Su always responded to requests. She only asked for two, but Niu Su gave her ten directly, all of which were made of ceramic, which was very thoughtful.

And because it was a bit cold these days, I just gave one to my brothers and parents, and Xiao Jingyi also gave one.

At first, the whole family didn't believe her when she said that the hot water inside could stay hot all the time without being warmed over the fire. It was not until the whole family gathered together to experiment for most of the day that they believed it.

When Qin Zhongyue took out the kettle, she really didn't expect that her second brother and Xiao Jingyi's brains would work so quickly.

"After that person finished this for me, he left Beijing, saying that he had something else to do and he didn't know when he would be back."

When Xiao Jingyi and Qin Erlu heard that the person who made the thermos had left, they immediately showed anxious looks on their faces.

"But I think this isn't difficult. Let's study it ourselves and see how it's done. Maybe we can make it ourselves."

Qin Zhongyue really thought so. The principle of the thermos cup is quite simple. In fact, it is to isolate the inner liner and the outer layer, prevent air circulation and conduction to dissipate heat, so as to play the role of heat preservation.

Of course, the materials are also somewhat particular, and the material with the best thermal insulation effect is definitely steel.

Forget about steel here, at most we can get some iron or copper.

"Sister, if you can really do it, you will have done a great deed.

I would like to thank you on behalf of the frontier soldiers."

Xiao Jingyi also nodded. He did not interrupt his uncle and sat aside very obediently.

Qin Erlu's mood turned from gloomy to bright, and he was very excited. As long as his sister said she could try it, then he would definitely be able to do it.

Ever since my sister stopped being so foolish as to associate with the Shen family, Engen has been able to accomplish whatever she wants to do.

Moreover, this matter must be reported to General Bae, who must support him.

It would definitely cost money for his sister to do all these things, and he would not let his sister do a business at a loss. He wanted to be a good general, but not at the expense of his own family's interests.

He still remembers the original reason why he chose to go for it.

Of course, if he has the ability, he would still like to make life better for his soldiers. This is also his duty as the General of the Central Army.

Not to mention Xiao Jingyi. Before his beauty was Qin Zhongyue, most of the money he earned was spent on his army every year.

If this thermos can really be mass-produced and provided to the soldiers, not to mention one for each person, even if two, three, or even four or five people share one, even if it can only keep heat for half a day, it is better than having nothing.

Moreover, this is also military supplies. As long as it is not too expensive, the army will probably be willing to buy it.

Even if it is a bit expensive, it is his princess who should earn the money. If not, there is still the emperor.

"Sister, how much does this thermos cost?"

Qin Erlu never thought about asking about the cost. His sister had to make some profit and couldn’t lose money.

"We don't know yet. It will definitely be cheaper if we do it ourselves. We won't know the cost until we do it."

It is to be used for the soldiers who defend the country, not to make dirty money.

She felt uneasy holding that kind of money.

She admits that she is rather snobbish and selfish, but she still knows clearly what can and cannot be done.

"If ordinary people want to use it, they can afford it, but the materials may not be as good and the effect may not be as good, but it is good enough.

Soldiers must use something better, made of better materials, preferably copper or iron, which is not easily broken."

Qin Zhongyue said this and looked at Xiao Jingyi who had been silent.

Xiao Jingyi understood immediately, "I will tell the emperor, this is a good thing, he will definitely agree."

"Your Majesty, I will talk to General Pei later. If General Pei goes with us, we will have a better chance of winning."

Xiao Jingyi nodded. Even if he didn't tell General Pei, he would still go find General Pei.

Qin Erlu wanted to run to Pei's house right now and talk to General Pei about the benefits of thermos bottles, but he held himself back.

Let’s wait until my sister figures out what she’s doing before we talk about it.

If I say something first but fail to do it, then doesn't that mean my sister is lying and disappointing me?

Since Qin Zhongyue agreed, he started to do it.

I mentioned this matter when I connected with Niu Su the next day.

Niu Su felt that this was a meaningful thing and was willing to help Qin Zhongyue. The materials Qin Zhongyue wanted were not very good and could be obtained here.
