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

Perhaps if you want to know the answer, you can only ask the system yourself. Only the person who grants this ability knows the origin of these abilities. The next day after the energy was replenished, Chen Yu got up early in the morning.

First, he went to the distant Yu Yuzhong to cut some tender grass to feed the livestock, and then went to the smokehouse to turn the smoked meat over to make it easier to roast thoroughly. After doing all this, it was already bright. After dinner, Chen Yu prepared to set off again to the freshwater lake to build a shelter. But before building the shelter, Chen Yu wanted to do one thing.

That is to recast a big knife and update all the ironware in the house.

Because his sword had been completely destroyed in the last battle, it had become a pile of fragments and could not be salvaged. However, due to the support of materials and conditions, Chen Yu was able to rebuild a better iron weapon this time.

Chen Yu took the meteorite he picked up from the sea, and then found some iron ore with a very high iron content from the hematite vein and carried it back to the freshwater lake.

There is a ready-made earthen kiln and a large pile of coal. The materials are fully prepared and all we need to do is start the work!

Chen Yu quickly started the earth kiln to burn. Because he added some random mineral stones into the earth kiln, the fire was very strong.

However, this temperature is far from enough to quickly dissolve hematite into iron blocks.

Therefore, in order to ensure that the temperature continues to rise, Chen Yu even customized a huge bellows with wood next to the earthen kiln. This bellows is used for blowing air, and the strong wind will promote the increase of the fire and increase the temperature of the fire. The higher the temperature, the faster the hematite melts. The temperature of the modified earthen kiln rose to a terrifying level. As the temperature rises, the hematite inside the earthen kiln also melts into molten iron and lime. Although the amount that can be harvested at one time is not large, the efficiency has been greatly improved now. Therefore, it didn't take long for the first batch of pig iron, which was quite a considerable amount, to be forged. Now Chen Yu has produced enough pig iron, enough for him to create various necessities of life. If you want to improve the quality of pig iron, the first thing is to remove all the superfluous elements in the pig iron.

Especially the carbon element in the iron block, which must be hammered repeatedly to knock out all the carbon elements with a hammer. Only when the iron block becomes harder and more resilient, an iron close to wrought iron and steel is completed. Following the steps step by step, Chen Yu quickly melted the iron ore into molten iron. After a series of steps, Chen Yu finally began to forge pig iron. There was a huge stone slab at the door, and the stove was burning.

Chen Yu hammered the iron block again and again, and the chickens that were originally hidden in the iron block were being hammered out. Finally, with a crisp sound, Chen Yu knew that the fine iron was ready! Sharpening the knife does not delay the chopping of wood. Chen Yu directly made the iron into a hammer, and then used the remaining iron to make an anvil.

This way, he can more conveniently use the advanced tools in his hands to create stronger knives and ironware!

As the sound of the anvil hammering sounded, Chen Yu's sword took shape in his hands.

The first thing Chen Yu made was the hammer, and then with the hammer, he gradually made kitchen knives, axes, shovels, hoes and other tools. By the time he had made these things one by one, two days had passed!

It took Chen Yu two whole days to make these pieces of farm furniture. The next thing he had to do was to make his big knife. There were already seven or eight iron blocks next to the stove, each weighing at least one or two pounds.

These are the iron blocks that have been forged for the first time. Next, they need to be melted into molten iron again with a high fire. Soon, under the high temperature burning, the iron ingots have been completely melted into molten iron.

The molten iron was poured into a specially prepared mold and waited for solidification. Not long after, a rectangular iron bar appeared in Chen Yu's hand. This was the iron bar he used to make the machete, but the quality was not up to standard. Chen Yu put the iron bar into the furnace to burn, and when it was red hot, he took it out and hammered it.

This knife was made very meticulously. Every part of it had been hammered by his hammer, and he knew every part of the iron body very well. Soon, the iron bar gradually became much smaller from the thickness of an arm, because the impurities in it had been beaten out. Then, the iron bar was hammered and shaped by a special method, and then quenched and sharpened!

Chen Yu ensured that every step was performed by himself, and the knife he created was most suitable for Chen Yu in terms of weight and shape.

Among them, the quenching process is the most important, because it is related to the quality of the knife!

Therefore, Chen Yu mixed many liquids with different densities, and used different liquids in each quenching. The last step was sharpening, which was not a complicated process. After a whole day of repeated forging, Chen Yu's knife was ready! It took more than a day and almost two days, and a big knife was completed!

Now his sword looks very sharp. Although its craftsmanship and quality may not be as good as those of Longquan swords from other places, it is definitely not bad!

This knife weighs more than five kilograms, which may be a bit heavy for most people.

But for Chen Yu, it was just right, not too heavy or too light, and he could easily control it. Chen Yu picked up the machete and came to a tree trunk as thick as a bowl, aiming at the trunk and chopped it hard!

"Bang! Boom!"

With a loud noise, the tree fell to the ground, and the cut was smooth and neat. This was the sharpness of the fine iron sword. With this sword, who would he be afraid of in the future?

When he released the machete to chop the big snake, if the machete was not of poor quality, and it was replaced with this one, then it would not be as simple as letting the black python run away.

If it was this knife that chopped it, the black python would have been bleeding, not Chen Yu's knife. Chen Yu held the big knife in his hand, and felt like he couldn't let it go. He simply found a piece of iron wood to make a scabbard for him to carry. After making the big knife, Chen Yu always wanted to melt the meteorite from the seabed and make a big knife. But what made Chen Yu feel helpless was that no matter how he burned the meteorite, the stone didn't change at all! Chen Yu didn't believe in evil and burned it with fire for three consecutive days, but there was still no reaction!.
