Tang Zheng feels that he is now trapped in Luke's paradox.

The so-called Luke paradox is a copy of the original world's popular online games, Luke Tuan Ben.

In this group book, you can get a set of the most awesome suit, named hebolen.

So the paradox was born.

Player: "Captain! Let me in and fight the regiment! (loud)"

Commander: "you have to have hebolun before I can let you in to fight! Otherwise you won't hurt! (disdain)"

Player: "I have to fight in groups first, and then get the materials to make hebolun! (loud)"

Captain: "I told him very clearly. You have to have hebolun before you can fight the regiment! So you can hurt!! (anger)"

Player: "I want to play in a fucking group, so I can make hebolun and hurt!! (roaring)"

……

Tang Zheng looked at the production materials of the furnace needed by the synthesis platform and couldn't help falling into meditation.

[stone * 20] + [iron block * 5] + [clay * 10] = furnace

He had to have a furnace before he could make iron.

But the system told him that he had to have iron before he could make a furnace.

Of course, there is more than one solution to everything in the world.

It is as difficult as Luke's paradox, and it is not completely without a solution.

No, hebolen can enter the regiment by head py or drive the Mammy.

But some nannies put the cross on the ground when they entered the picture.

The intelligent human ancestors, without a furnace, still extracted the first batch of metal iron.

The ancients also had the wisdom of the ancients.

That is, the most primitive boiling water purification method.

Don't ask how Tang Zheng knows.

Tang Zheng turned off the atlas of all things.

……

To make iron, you first need to take iron from iron ore.

The purity of the iron ore mined by Tang Zheng is not very high. It contains many other minerals such as sand and stone.

If the iron is refined together, the purity is very low and the durability is very poor.

Its internal stability is also very poor, and it is easy to crack.

Therefore, it is necessary to polish and purify before using the most primitive boiling water purification method.

After thinking about it, Tang Zheng chose to start the graphic live broadcast.

Don't miss any chance to raise the level of the forum.

This method of ironmaking is only one-off. After the subsequent furnace is manufactured, he does not need to make iron manually.

So even if this primitive ancient method is learned by others, it doesn't matter.

In terms of efficiency, they are always one step behind me!

Low key sneak Walker: "all in, old fellow blacksmith free online to teach you ancient iron making!"

The post has just been sent out, and many players who pay attention to him click in instantly.

[old fellow sauce?]

[front row! Low-key giant, acting hot again!]

[tongs, Liu Ming!]

[I know! Ironmaking? Low-key giant. How can this civilization develop at the same speed as a ghost!]

[brothers, I'm in a bad mood! I've just polished my first stone axe. Before I could be happy, I turned around and saw that the low-key giant was making iron... Is this how to play the game?]

[today is the sixth day of survival. According to this posture, you can make iron on the seventh day?]

[seven days from zero row to iron age? WTF? This NIMA can't even catch up with Luban?]

[the one in front, don't watch the dust?]

[Mo what?]

The number of post replies surged. I have accumulated a lot of experience since yesterday's graphic live broadcast dinner.

Today, as soon as I opened the post, I directly broke through the forum level of level 15.

The bright red ID has changed slightly at this time, and a trace of orange can be vaguely seen.

"It seems that the forum level of level 10 can change the ID color once. It's about level 20. You can get the orange name." Tang Zheng thought to himself.

Orange name can produce 4 virtual coins per day and increase all attributes by 3%.

Since the prophet's post, the value of virtual currency has begun to rise.

If his prediction is true, the forum store can only buy props with virtual currency after it is opened.

Its value is self-evident. Tang Zheng is glad that he has hoarded more than 500 virtual coins.

The 3% of orange names seems rare, but the value lies in all attributes.

Took a picture of iron ore with words.

[in the original environment, iron refining needs to be carried out first.]

Tang Zheng took a big stone, put the iron ore on the hard ground, picked up the big stone and began to smash it.

The purpose of this step is to smash the iron ore into particles, separate the iron from other minerals, and then extract iron particles from them.

This is much easier than mining iron ore.

Because the mined iron ore is small and angular, it can be started from the edges and corners.

From early morning to near noon, and then update the latest progress in the forum from time to time.

Many people witnessed Tang Zheng smashing a large iron ore into countless small particles.

After a full meal at noon, work will continue in the afternoon.

Finally, near the evening, a large iron block was completely smashed into countless particles the size of gravel.

The forum level has also been raised from level 15 to level 16, and the color is orange.

Taking advantage of the last light in the sky, Tang Zheng held a pile of gravel on the ground and spread it on a board.

Touch out a stone stick in the shape of a rolling pin and grind the already crushed iron ore into fine powder.

Of course, because it is a hard mineral, it is naturally not as delicate as edible flour.

Then, I went to the water point (water vine) and brought back half a bucket of water, lit a bonfire again, put it on the bonfire and began to boil water.

[if you don't understand, don't you want to make iron? Why is it boiling water?]

[tired all day, take a hot bath, what's the matter! / dog head]

Tang Zheng glanced at the comments and took time to type back.

[prepare water for ironmaking.]

Suddenly, there were hundreds of question marks.

[boiling water and making iron? Are you teasing me?]

[I've lived for more than 20 years. I first heard of the idea of boiling water to make iron]

[let me tell you what the operation is.]

[old fellow blacksmith, uninvited. Low key should just want to extract iron metal, not iron smelting in real sense... But I really see the first time when I use water to extract metal. I don't know how he works.

[it's said that it's true that a low-key giant is a survival expert, but this wave is a little suspected of cheating the recovery experience?]

[is there a brother who opened the market? I bet a virtual coin. If I keep a low profile, I will overturn!]

Hundreds of floor replies, say anything.

Tang Zheng swept by without saying much.

In fact, he secretly learned this trick, and I don't know where the atlas of all things turned out in the historical documents.

It has been lost for a long time and belongs to the metal refining method invented by ancient primitive ancestors.

Not to mention that modern people have never heard of it, even ancient people may not have heard of it.

After taking a look at the boiling water, Tang Zheng began to prepare for the first metallurgy of primitive civilization!
