After talking to Coin Coin 559, Muying felt a lot more relieved.

The female vampire is not so strong that she can never be dealt with, and her strength will be weakened by sunlight. Although her potential is high, her upgrade speed is not that fast, so she is not a big threat for the time being.

Don't worry about the next generation yet. After issuing the repellent potion, no newborns have been born in the territory, so just keep it in mind.

I planned to go back and continue practicing spells, but suddenly I received a call from Professor Han, asking her to visit the iron smelting camp.

Professor Han is the materials scientist recommended by Professor Su before. His ability is indeed very good. He is now the person in charge of the iron smelting camp. Mu Ying has also left many other candidates with expertise in this field, all led by Professor Han.

Studying iron and steel making and equipment refining!

After receiving the call, Muying teleported to the iron smelting camp.

The iron smelting camp and the quarrying camp are relatively close, but the area is not very large. The stone mountains have been flattened and replaced by a tall stone factory building.

The employee dormitories, ironmaking area, iron ore storage area, fuel storage area and output warehouse are all here.

Muying teleported to the iron-making area and saw that all the iron-making workers were gray-haired and their clothes and hair looked like they hadn't been washed for weeks, including Professor Han.

"Lord, we have failed to trust you. The steelmaking failed." Professor Han told her the bad news as soon as she arrived.

Muying was a little surprised when she heard this.

Professor Han is an expert in materials. Even if the conditions are not as good as before the end of the world, there should be no problem in making iron and steel using the most primitive methods. How could it fail?

But looking at their looks, you can tell that it's not that they didn't work hard, so there should be other unexpected situations.

Muying asked calmly: "Have you found the reason?"

"As you know, we originally wanted to make steel, use iron as the back of the knife, and just make the blade. The weapon made in this way has a tough edge and is hard and sharp, and is no worse than a white quality weapon.

Before the end of the world, we had thoroughly studied the properties of steel. Steel is an iron alloy with a carbon content between 0.02% and 2%. Anything outside this range is iron, and pig iron has a higher carbon content.

Hard and brittle, with low carbon content, wrought iron is soft and has good plasticity.

But now the properties of iron are different. What we smelted strictly according to the method of making iron and steel before the end of the world is very different from our goal. We investigated all the reasons and finally came up with an incredible answer: the properties of the material itself have changed.

Already."

Professor Han sighed and continued: "And I suspect this may not be an isolated case. The burning duration and temperature of coal have increased compared with before the end of the world. Maybe the properties of many materials have changed. In this case, I

The knowledge I have learned for most of my life may no longer be applicable. If I betray your trust, it may be difficult for me to be qualified for this position!"

It can be seen that Professor Han's self-confidence has been deeply affected.

The properties of the materials had changed, which indeed caused the knowledge he learned to have no practical significance, but Muying did not think that his previous knowledge was worthless.

"Don't worry, so what if the properties of the material change? If you continue to study it, you definitely don't have only a brain of knowledge about the properties of the material. Just treat the current iron as a brand new material and study it. Don't you before the end of the world?

Have you been working on new materials? As for the benefits of the iron-making camp, you don’t have to worry. The temporary territory can still support it. We don’t use the iron ore ourselves. In the end, it will be sold as raw materials or directly converted into energy, which is very uneconomical.

."

Muying comforted him and said: "And the properties of materials have changed, which is not a bad thing. Take coal, you said that its burning temperature is higher and its durability is longer. This change is good, iron

The same may be true for mines. As long as we find out its properties and characteristics, it might be even better than the iron before the end of the world!"

The original intention of building the iron smelting camp was to refine the iron ore produced in the iron mining camp and earn more profits by selling it. It was just an investment.

Therefore, she can accept the lack of output for the time being. Even if she starts researching the properties of materials from scratch, the territory can still support it. At most, she will only need to invest a little labor cost, and the iron ore is self-produced.

Even though she was a little concerned about the change in material properties, she was mostly optimistic.

Iron ore and coal mines appear to have no difference in appearance before the end of the world, but their properties have changed, but this change still does not deviate too much from their own properties. Iron ore is still hard and can be used as weapons and tools, and coal is still combustible and can be used as fuel.

Think about it again, isn’t the purpose of the doomsday game to promote the evolution of the entire planet and even the creatures on it?

Humans, plants, and animals have all ushered in evolution, and generally they are developing in a good direction. It is normal for inanimate material materials to have evolutionary mutations, and there is a high probability that they will be good.

The only drawback is that many of the experiences gained before the end of the world are discounted or completely unusable now.

But what you learn before the end of the world is not only knowledge, but also methods. If you never change from the original principles, if the methods are still there, you can master the knowledge again.

"I'm making you laugh. I'm old, and it's not as easy as you young people think. It's a blessing in disguise. It's my fault." Professor Han sighed, "But thank you for your trust. I promise to do my best."

He has worked hard all his life to research new materials for his territory and meet challenges!"

"Okay, research is not for a while. Don't wear out your body. Look at the dark circles under your eyes. Stop working today. Take a day off and go back to have a good rest. You can start working again when you are full of energy!" Muying said.

She is not a shady boss. Let's not forget about the apocalypse. Her subjects were not injured or killed in the battle, but died suddenly at work. That would be a sin.

A holiday was given to the workers in the iron smelting camp. Seeing that everyone had gone back to rest, Muying said to Professor Han: "You don't need to be too stressed. I will go and inquire about the iron for you and see if I can give it to you."

Ask an instructor to come back."

Professor Han rolled his eyes, "You mean Old Lu Bo?"

Muying nodded, "The current Deep Blue Star is no longer the former Deep Blue Star. After becoming a part of the multiverse, it is an overall evolutionary improvement. Although he is not as good as his two sons, he is just a person who can make inferior tools.

An ordinary blacksmith, but he has been working with iron for a lifetime, so he should still know the properties of iron."
