Hand rubbing nuclear fusion live in the wilderness

Chapter 61 The Assumption of Forging Iron Saw
The sun was setting, and by the bonfire, Han Yuan gnawed on the heart of a banana tree as a fruit, while looking at the personal information panel.

"System, how did this technology point come from?"

He is still quite curious about the two new things that came out of this update, as well as the so-called completion task.

"Technology points come from various technologies made by the host, such as stone hammers, stone axes, iron hammers, and iron axes."

"The more difficult the manufactured item is, the higher the number of technology points obtained, and each technology item can only obtain technology points once."

"The civilization technology mastered by the host can also get technology points for upgrading and leapfrogging."

"So it is."

Han Yuan nodded. He has polished stone axes, stone hammers, iron axes, and hammers these days, and the level of civilization and technology before has changed from nothing to 'Stone Age+'.

Technology points have always been obtained from these places.

After thinking for a while, he then asked, "System, apart from increasing the number of times the metal detector can be used, are there any other uses for these technology points?"

"The current authority of the host is not enough, please work hard to develop technology and improve the level of civilization."

Han Yuan was speechless. He used to see this kind of thing when he was reading novels, but he didn't expect it to fall on him now. It's cheating, this is.

Sighing, he closed the personal information panel, and fell into deep thought.

The casting of ironware opened a branch in the supplementary task. As long as three different pieces of ironware were cast, he would be able to harvest a metal detector.

Although it can only be used in this simulation space, it makes up a lot of things.

We must know that the higher the technological civilization climbs, the greater the dependence on various raw materials.

Especially various metals and alloy materials.

If there is no metal, it is impossible for human civilization to embark on the road of scientific and technological development.

In other words, it is impossible for human civilization to appear at all. Even if it did appear, it may still be stuck in the Stone Age and unable to move and progress.

Just like today's gorillas, although they can use stone tools like ancient humans, it is impossible for them to evolve into another human being.

Unless all human beings disappear, it may be possible in a few million years.

Of course, that's not what he was thinking about.

If forging metal tools can make the completion task branch, and harvest the metal detector.

So is it possible for other modules in the completion task to have this kind of branch task?

Thinking of this, he opened the mission information panel again, which also displayed the completion mission and completion mission branch.

He has actually done all the conditions in the four completion tasks.

Needless to say pottery, this is the first one to make it, and he still has a clay basin and a clay bowl in his hand.And he plans to burn a few more in the next two days.

Needless to say, stone tools, stone hammers, stone axes, and stone knives are all there.

Not to mention ironware, iron is being smelted all day today.

As for the weaving of clothes, in a sense, weaving hemp rope shoes is also one of the clothes.

The only difference between these few things is that the ironware is made after the completion task is triggered.

If the branch task can only be triggered after the completion task appears, then the remaining three may also trigger this branch task.

After thinking about it, he decided to try tomorrow and make one of three different types of things to see if he could trigger a branch task.

Although I don't know what the remaining three will give, but mosquitoes are no longer meat, and he wants everything that can help him.

The bright moon is in the sky, and there are no clouds in the sky.

After dinner, Han Yuan sat and rested by the bonfire, holding the piece of iron that failed to refine this afternoon and looked at it carefully.

It's not discouragement, it's just a failure, it's nothing.

He is not someone who gives up so easily, he is just thinking about how to deal with this piece of iron.

To be honest, he no longer had any hope of turning this piece of pig iron into one, forging it into a knife.

Because he didn't have borax as a flux in his hand, and the hammer was too small and not heavy enough to beat the two pieces of iron until they fused.

In the light of the fire, he examined the piece of pig iron.

Although the two iron sheets are closely connected, there is still a gap visible to the naked eye in the middle.

The potholes and depressions on the top have been forged and flattened a lot compared to when they were just out of the furnace, but the holes are still there, and there are two on the edge of the iron sheet.

Although after the iron sheet is disassembled, a short dagger can be made from the relatively complete side.

But he wanted a better way to deal with it.

Suddenly, looking at the hole on the edge of the iron sheet, he suddenly remembered something, and held the iron sheet in front of his eyes.

He has a bold idea!

If a part of this piece of iron that is full of holes is removed, and then forged and elongated, a hacksaw can be produced.

From an idea point of view, it is entirely possible.

Although there are holes in the iron sheet, and some places are still very thin, these parts can be removed without affecting 0 too much.

The most important thing is that this piece of iron is heavy enough.

Even if one-third of the iron is removed, the remaining part is enough to be forged, stretched and thinned, and then a thin and long iron bar can be produced.

Although pig iron has a high carbon content and is brittle in nature, he can forge it several times, and it can always be formed.

As for how to cut the saw for the hacksaw, the iron ax in his hand can do it.

Pig iron is much harder than wrought iron that has been forged many times, and an iron ax can cut out the saw kerf bit by bit.

If you have a hacksaw, then you can save a lot of trouble when cutting and trimming trees to make a wooden house.

And the removed iron does not need to be wasted, it can be collected and returned to the furnace to be remade to make iron nails one by one.

With this thought, Han Yuan's eyes brightened instantly, wishing to forge it now.

Playing with the iron piece in his hand, he put it back into the bamboo basket, went back to the cave to sleep, and prepared to forge the hacksaw when he got up tomorrow.
