Rebirth before the doomsday: I quietly emptied the city of supplies

After the iron in the iron ore melts, they will all stick together, but some of the sand and gravel in the iron ore will wrap around the surface of the iron block. And now the layer of red stuff they can see is actually not iron ore, but just sand and gravel wrapped around the iron block! Chen Yu gently pushed the burned iron block onto the stone slab with a bamboo stick. Then he found a half-meter-long wooden stick and kept hitting the iron block. Suddenly, the sand and gravel wrapped around the surface of the iron block were smashed off bit by bit...

The innermost layer of sand and gravel was difficult to remove, so Chen Yu could only use his ordnance shovel to knock it down slowly! However, even after removing the sand and gravel on the surface, Chen Yu still got a pure iron block the size of a bowl. If you make a machete or an axe, there should be some left... "Chen Yu, why is this iron black? Shouldn't iron be silver?" Looking at the black block, Ling Qing asked in confusion. "What we refined is pig iron, which is silver-white in color."

"The reason why the surface is black is because it is covered with a mixture of black ferric oxide and dark brown ferric oxide." "That's why it appears black. As long as we grind off its surface, the inside will be silver-white pig iron!" Chen Yu explained...

All this knowledge is part of the wilderness knowledge package rewarded by the system.

Although I am interested in wilderness survival, I would never study this kind of thing for nothing... "Oh, so that's how it is!" Ling Qing nodded, not quite understanding.

She didn't have much education, so she didn't know much about ferroferric oxide or ferric oxide! "Fuck, did Chen Yu really smelt pig iron from iron ore?" "Incredible, is there anything this guy can't do?"

"When he picked up the hematite, I thought he was just picking up a few rocks to put in his pen!" "This guy is simply the all-around king in the wilderness..."

"That's awesome. I have to admire you. Even if ordinary people find hematite, they don't have the patience to refine it into raw iron!!" "Chen Yu is so handsome. I want to give birth to a baby for you..."

"Please be reasonable above me. If you get together, you can only give birth to a pig, not a monkey!!" "Get lost, you idiot..."

"Brother Chen Yu 666..." Godkiller: "Reward the anchor * 666 shark balls..." Cute little rabbit: "Reward the anchor * 66 shark wings..."

As Chen Yu successfully refined iron, the comments and rewards in the live broadcast room became lively again. Many people in the wilderness basically think about how to fill their stomachs and how to survive!

Who would want to do something as boring and time-wasting as iron smelting? In a special live broadcast room...

"Teacher Xiao, what do you think of Chen Yu's refining of pure iron?" Lin Bin looked at the dark black object on the screen in surprise and asked Xiao Qiang. Xiao Qiang has experience in surviving in the wilderness, so he might be able to make a qualified comment on Chen Yu's approach.

"I'm sorry, Mr. Lin, I really can't comment on this. Although I'm an expert in wilderness survival, I don't know anything about smelting iron ore..."

Xiao Qiang shook his head and answered sincerely.

Because he didn’t understand, he couldn’t give any comments or opinions…

After hearing what Xiao Qiang said, Lin Bin stopped asking any more questions. Anyway, even if he continued to ask, he probably wouldn't get any hot topics!

...

In the wilderness, Chen Yu had almost removed all the impurities from the pig iron.

There are definitely some impurities left, but with my current conditions and technology, I can't completely remove all the impurities! "Chen Yu, what should we do now?" "It's hard to make such a big piece of iron into a machete, right?"

Ling Qing looked at the black piece of iron and asked with some confusion.

She had seen the process of blacksmiths forging iron tools, but they all used very large hammers to forge them. They didn't have those things now.

"Actually, it's not that difficult. I just need to melt this piece of iron into molten iron again and then pour it directly into the model I just made, and that'll be it!" Chen Yu said as he thought.

But now if I want to melt the iron block into molten iron, then the earthen kiln I just used must not be used! Because I need a container to melt the molten iron. Otherwise, even if I melt the iron block, it will become an irregular iron block.

Now at least I have made that big earthen kiln, which can be put to use...

As long as you put the iron block in the pottery you made, and then burn it at high temperature, the iron block will melt into molten iron in the bowl. Then you can pour the molten iron into the model! Thinking of this, Chen Yu immediately started to execute. Put the iron block in the pottery bowl that is at least thicker than the one that is qualified for firing, and then raise the temperature in the earthen kiln to 1538 degrees Celsius!

At this high temperature, when the core temperature of the pig iron reaches 1538 degrees Celsius, the whole piece of iron will melt. At that time, you can take out the bowl of molten iron with a wet hibiscus tree!

"Oh, then do we have enough firewood now? If not, I will go and pick up some more." Ling Qing asked.

Although I don't know how to do it, it will probably take a lot of firewood to melt the iron, right? "Well, go pick up some more, but don't go too far..." Chen Yu looked at the firewood on the ground and said. Although the current firewood should be able to melt the iron into molten iron, just in case, it is better to find a little more firewood. Firewood is very useful anyway, and there is no fear of not being able to use it up.

This time, melting the pig iron seemed to take longer than the last time. After six hours, Chen Yu finally saw the iron melted! After gently pushing the bowl in the earthen kiln with a branch, the molten iron inside was shaking. This means that the iron ore has now been forged into molten iron... and it can be made!

Chen Yu picked up the pliers he had just made from the wet hibiscus tree and clamped the edge of the ceramic bowl tightly. Instantly, the hibiscus tree made a sizzling sound, accompanied by thick white smoke and sparks. Chen Yu poured the molten iron into the finished model as quickly as possible. Sizzling... As soon as the molten iron, which was as high as a thousand degrees, touched the ground, it made a very terrifying sound. The molten iron was boiling and splashing everywhere.

"Get out of the way..."

Chen Yu pulled Ling Qing aside.

If you are hit by this kind of thing, it will definitely leave a deep mark! Then Chen Yu quickly poured the remaining molten iron into the axe model. It also made the same harsh magnetic sound. The red molten iron turned black little by little...

At this time, while the molten iron had not completely solidified, Chen Yu quickly used his knife to trim the uneven edges and corners. Then he poured water on them until the machete and axe were completely solidified. After they were completely cooled, Chen Yu used a military shovel to dig them out. Then he washed them in a basin!
