The equipment of ancient weapons was basically made of iron.
Although iron is considered a very hard metal, when the two countries go to war, the weapons of other countries are also made of iron. At this time, we have to see who makes the weapons with more exquisite craftsmanship.
The way Zhao Yun'er thought of was to change the material used in the weapon, from iron to just steel.
As a person of the 21st century, Zhao Yun'er was considered to be a semi-academic master when she was in school. She was good at chemistry, and she happened to know about steelmaking.
The method is not difficult. Add some lime to the original refined iron. After a series of chemical reactions, the oxygen in the iron is removed. After continuing to forge, it becomes steel.
Zhao Yun'er only knew how to do it theoretically, but she was not sure whether it would actually work or whether she could forge steel, so she just tried and experimented, and if it really didn't work, then there was nothing she could do.
Of course, if it succeeds, that would be even better.
The hardness of steel is definitely much harder than iron, and the weapons made are definitely harder.
When they arrived at the mountain, Mu Lianfeng didn't expect Zhao Yun'er to come suddenly, so he asked, "Yun'er, what's the matter with you coming?"
Zhao Yun'er looked at Mu Lianfeng's eyes, which were bloodshot because she hadn't had a good rest in the past two days.
If I don't find a solution this day, I can't rest for a day.
Zhao Yun'er smiled and said, "I'm here to help you."
Mu Lianfeng was very confused, "Help us?"
"Yes." Zhao Yun'er nodded, "Didn't you say that you want to improve the quality of weapons? I have a way to try."
After Zhao Yun'er finished speaking, Mu Lianfeng was silent for a moment and looked at Zhao Yun'er in disbelief.
"What, you don't believe me?"
Mu Lianfeng shook his head, "No, Yun'er, you are very tired every day. You still have to worry about me about my affairs. I am really useless..."
There was a bit of self-blame in Mu Lianfeng's tone, and Zhao Yun comforted her, "I'm not worried, I just heard you and Mo Yan discussing this matter yesterday, and I just thought of a way, try it first, it will be better if it works ,alright, that's fine."
Mu Lianfeng nodded heavily, but his heart felt a little more hopeful.
If it really happened, then he could have some leisure time and spend time with Zhao Yun'er and Doudou. In addition, I have something to explain to the emperor. Once the emperor is happy and satisfied, it will be easier to make any requests.
"Okay, then Yun'er, let's try it first."
"Yeah." Zhao Yun'er nodded.
Mu Lianfeng followed Zhao Yun'er's request and called Mo Yan over to join him.
Mo Yan was equally happy when she heard that Zhao Yun'er had a solution.
In the past few days, he, like Mu Lianfeng, had been worried about this matter, but he still couldn't find a way.
Seeing that the deadline set by the emperor is coming soon, if I can't think of any way, it will be over.
"Madam, why are you so powerful? Master and I have been thinking about what to do for several days. I didn't expect that you would come up with a solution after listening to it last night. If I had known better, I would have told you earlier."
Zhao Yun'er was amused by Mo Yan, and the flattery was quite good.
However, Zhao Yun'er still took a preventive shot in advance, "It's just a try, it may not work, so don't have such high expectations."
"It's okay, madam. It's better than whatever the master and I can't think of."
"haha, okay."
Soon, Mo Yan finished the work according to Zhao Yun's instructions.
