I'm Still Too Weak with Sss Talent at the Start

Substances that are denser than water will sink.

Those with a density lower than water will float upwards.

Using this principle, at the beginning, human ancestors used floating water to extract iron particles.

Throw the ground iron minerals into the water together, and skim off the floating ones with a slotted spoon. After the bottom is dried, it is naturally iron metal, which is used for forging.

But soon, people found that this method was not as easy to use as expected.

Forged iron still has a lot of impurities, and its lifespan is not long. It is a little easier to use than stone tools.

Forging iron tools is a hassle, and if it's only a little better than stone tools, why bother?

So human ancestors pondered.

What the hell is going on here?

After thinking about it for a while, he finally saw through the essence and found the reason.

Because there are always some minerals, it may be denser than water, but less dense than iron.

What if we sink together?

Wouldn't that be thick iron doped with various impurities?

So the human ancestors changed another way.

Still using the buoyancy of water, but this time using boiling water.

When water is heated to the boiling point, it will keep tumbling, and this common sense is known to everyone.

The rolling force can drive some relatively light and fine particles to roll together.

Using this, it is possible to further exclude those substances that are heavier than water and lighter than iron.

There is also the first relatively complete method of refining iron particles in history, the boiling water refining method.

Even compared to the current shaft furnace refining, magnetic refining and other high-tech methods of refining iron metals, the ancient and cumbersome method of boiling water refining has long been eliminated.

But the birth of this method has made a huge contribution to the advancement of human civilization.

Tang Zheng plans to use this method now to extract higher-purity iron and send it to the synthesis table.

Watching the boiling water keep tumbling, Tang Zheng poured all the iron ore particles ground on the wooden board into the tumbling boiling water.

Visible to the naked eye, the originally clear water instantly turned earthy gray, with a lot of impurities rolling on it.

Due to insufficient technology at this stage, it is impossible to make a colander. After Tang Zheng waited for the boiling water to tumble for a while, he wetted his hands with cold water, and quickly raised the bonfire with both sides of the bucket.

Then slowly pour out the sewage in the bucket, and some impurities floating on it are also discharged.

The water was turbid, a bit like being scooped out of a stinky ditch.

At the end of the pour, there was still some water and iron particles left in the bucket, so Tang Zheng stopped in time.

He turned back to the wooden house and took out the linen that he had exchanged yesterday.

Tear off a small piece and lay it flat on the board.

Taking the edge of his pocket, he poured the remaining water and sediment in the bucket onto the cloth.

The water penetrated through the pores of the cloth, and some iron crystals with a dull gray-black luster were left behind and accumulated on the cloth.

Tang Zheng stretched out his fingers and shoved a handful of iron particles, rubbing them on the belly of his fingers.

Good iron will not fade unless rusted.

Fingers are still rosy.

It seems that in this primitive ecological world, the minerals that have been silent for tens of thousands of years or even hundreds of thousands of years are all the best raw materials, never mined or polluted, and have a high purity.

I took a photo of the result and posted it on the forum, ending this ironmaking post.

Instantly shut up a group of questioning voices, while harvesting a large wave of 666

The forum level exploded again like a rocket, soaring to level 17.

【Ding!Congratulations on completing 'Metallurgy'! 】

[Because you are the first 'metallurgical' player in the world, you will get a random item reward: the coordinates of the forest relics (excellent level) 1! 】

[Bronze Age Progress: (3/8)! 】

Looking at the first reward that followed, Tang Zheng's expression froze, and then he was overjoyed.

It seems that the version update predicted by the prophet is true!

I actually got a random coordinate reward of a forest relic!It's just that the version has not been updated, and the relic has not yet been implemented.

If he remembered correctly, the prophet had said that there were a lot of rich treasures in the ruins.

As long as the treasure is obtained, the difficulty of survival is almost qualitatively changed!

Although Tang Zheng now has no shortage of the most basic survival resources, there are still many obstacles to his further development.

He has been developing his civilization crazily in recent days, and his stats have stagnated.

I am afraid that it has long been surpassed by some people with attribute talents.
