Chapter 875

The equipment of ancient weapons is basically iron.

Although iron is considered to be a very hard metal, but when the two countries are fighting, the weapons of other countries are also iron. At this time, it is necessary to see who makes the weapons with more exquisite craftsmanship.

The way Zhao Yuner thought of was to change the material used for the weapon, and change the material for making the weapon from iron to steel.

As a person in the 21st century, Zhao Yuner was considered half a scholar when she was in school. She was good at chemistry, and she just knew about steelmaking.

The method is not difficult. Add some lime to the original refined iron, and after a series of chemical reactions, the oxygen in the iron is removed, and it becomes steel after continued forging.

Zhao Yuner only knows how to do it in theory. She is not sure whether it will work or not. She is not sure if she can forge steel, so she just tries and experiments.

Of course, it would be better if it was successful.

The hardness of steel is definitely much harder than that of iron, and the weapons made are definitely harder.

When they got to the mountain, Mu Lianfeng didn't expect Zhao Yuner to come over suddenly, so he asked, "Yuner, what's the matter with you?"

Zhao Yun'er looked into Mu Lianfeng's eyes, because she didn't rest well in the past two days, she had bloodshots.

If you don't find a solution this day, you can't rest for a day.

Zhao Yuner smiled and said, "I'm here to help you."

Mu Lianfeng was very puzzled, "Help us?"

"Yeah." Zhao Yuner nodded, "Didn't you say you want to improve the quality of weapons? I have a way to try."

After Zhao Yuner finished speaking, Mu Lianfeng was silent for a while, and looked at Zhao Yuner in disbelief.

"Why, you don't believe me?"

Mu Lianfeng shook his head, "No, Yun'er, you are very tired every day, you have to worry about me, I'm really useless..."

Mu Lianfeng's tone showed a bit of self-blame, Zhao Yun comforted, "I didn't worry about it, I just heard you and Mo Yan discussing this matter yesterday, and I just thought of a way to try it first, it would be better if it worked. ,alright, that's fine."

Mu Lianfeng nodded heavily, but there was a little more expectation in his heart.

If it really does, then he can relax and accompany Zhao Yuner and Doudou. In addition, there is an explanation for the emperor, the emperor is happy and satisfied, and it is better to put forward any requirements.

"Okay, Yun'er, let's try it first."

"Yeah." Zhao Yuner nodded.

Mu Lianfeng did as Zhao Yuner asked, and called Mo Yan to join him.

Mo Yan was also overjoyed when she heard that Zhao Yuner had a solution.

Like Mu Lianfeng, he has been worrying about this matter for the past few days, but he still can't find a way.

Seeing that the time limit set by the emperor is about to come, if there is no way to think of it, it will be over.

"Madam, why are you so powerful? My master and I have been thinking about it for several days, but I can't figure out what to do. I didn't expect you to think of a way after hearing it last night. If I knew it earlier, I would have told you earlier."

Zhao Yuner was amused by Mo Yan, and this flattery was not bad.

However, Zhao Yuner still took a precaution in advance, "Just try, it may not be successful, so don't have such high expectations."

"It's okay, ma'am, it's better than anything my master and I can't think of."

"haha, okay."

Soon, Mo Yan did as Zhao Yun said.
