Super Chief

　　 Shixiong ignored the tribesmen beside him. He picked up the arrow and looked at the wiped out place, with a smile on his face involuntarily.

　　 Without him, the silvery-white light revealed from the part where the oxide was erased is a very strong proof of the material identity of this arrow-I am a piece of steel! Real steel!

　　 Many people in later generations know that by distinguishing the color of metals, they can easily distinguish the difference between iron and steel.

　　Whether it is pig iron or wrought iron, it shows a gray color, while steel shows a silvery white color.

Although I don’t know if the arrow in front of me is low-carbon steel, medium-carbon steel, or high-carbon steel, there is no doubt that the color of the arrow has definitely confirmed that I didn’t have a white hair yesterday, and I came out by myself. The thing is really steel!

　　 The stone bear laughed loudly, and then under the horrified gaze of a group of people, he raised the stone hammer again, and slammed it down at the arrow.

　　 Li Lei and Kabru Sacrifice have all seen the process of Stone Bear smashing the three iron pots with this stone hammer, and they are very aware of the power of this stone hammer.

　　 An iron pan that is so big can't stand two hammers, such a small arrow, won't it have to be shattered with one hammer?

　　 This is an iron arrow. There has never been an iron arrow in the tribe. Arrows made of animal bones and stones in the past are powerful, but where are the iron arrows? Iron tools are much harder than bone tools and stone tools. This is the common sense of everyone in the tribe.

However, the stone hammer that smashed down with the exclamation of a crowd did not smash the arrow. The arrow was only slightly deformed, but whether it was the big rock underneath or the stone A small hole burst out of the hammer's surface.

　　This situation made a high-level member of the tribe exclaimed again—they had never seen such a hard iron tool.

　　 Ishikuma is completely satisfied now.

　　Everyone knows in later generations that whether it is pig iron, wrought iron, or steel, they actually have a common name, that is, iron-carbon alloy. It's just that the difference in carbon content results in huge differences in physical properties.

　　 Generally speaking, the higher the carbon content, the harder the iron-carbon alloy, but at the same time the lower the toughness. The carbon content of pig iron is more than 2%, so pig iron is very hard, much harder than steel, but similarly, pig iron is also very brittle, and some pig iron can even be broken when dropped.

　　Wrought iron is an iron-carbon alloy with a carbon content of less than 0.02%. Wrought iron has a soft texture, good plasticity, and good ductility. It can be drawn into wire, has low strength and hardness, and is easy to forge and weld.

　　 As for steel, it is a general term for iron-carbon alloys with carbon content between 0.02% and 2.11% by mass.

　　In other words, the hardness of steel is lower than that of pig iron, but higher than that of wrought iron. Similarly, the toughness of steel is lower than that of wrought iron, but higher than that of pig iron. In other words, steel is a metal with both toughness and hardness, so the use of steel is far greater than that of pig iron and wrought iron.

　　 If the carbon content of the arrow just now is too high, the arrow will inevitably be smashed when the hammer goes down. In the same way, if the carbon content is too small, this hammer will not break, but it will definitely flatten the arrow!

　　 But this arrow is not a big deal. It can almost prove that the molten steel produced by Shixiong yesterday is a medium-carbon steel.

　　 Although it is impossible to determine what type of medium carbon steel this is, Shixiong knows that with this thing, whether it is to build weapons or build civilian products, it is enough.

　　 "The great sun **** is here, the great sun **** bless us, we have succeeded!" Shixiong turned around, holding the half-black and half-silver-white arrow in his hand and smiled and said to several tribal leaders.

Then, he jumped on the big rock that was used as iron felt, raised the arrow in his hand high, and shouted at all the people around him: "My people, we We succeeded! We successfully smelted a material that is better than iron. This is steel! With steel, our people will no longer worry about not having iron pots, and our soldiers will no longer worry about not having iron. Quality weapons are available! My people, please remember this day, this day is a day worth remembering for our tribe, because from this day, our tribe will enter a new level, our Life will get better and better!"

Although the people of the tribe didn’t know what was going on, they couldn’t stand the big pot of chicken soup from Shixiong. It was too fierce. All the people of the tribe were excited by his pot of chicken soup. The breakfast full of meaty aroma and full of dancing came naturally.

　　The stone bear in a good mood ate a lot of meat. Of course, when he was eating, the people sitting next to him were all high-ranking tribes like Li Lei and Kabulu.

It’s really amazing what this mighty and robust guardian has done in the past two days. Although they don’t know how these cast iron tools are, they can turn three large iron pots into so many shapes. The different ironware, just this, is enough for the people of the whole tribe to regard the stone bear as an idol.

　　 Although there is no idol at this time, the people think so.

The 　　 meat is stewed by a mixture of bison and venison. Unfortunately, there is no spice, and it has a little salty taste. This is really hard for the stone bears who are used to eating food for later generations. The most important thing is that there is no wine here!

　　 If you drink wine again, UU reading www.uukanshu.com can’t really think of themselves as the sons of gods?

　　 But Shixiong knows very well that in the current situation where there is not enough food to eat, if he re-brewed, it would be a bit too unreasonable.

　　 But if you wait until the potatoes and sweet potatoes are harvested next year, you can make some "sweet potatoes". Anyway, whether it's sweet potatoes or potatoes, they are both high-yielding crops. Just a few thousand catties per mu of land is just like playing.

　　 After breakfast, Shi Xiong smashed all the remaining molds and took out the cast ironware.

　　 "Is this a knife?" Gao Niu asked excitedly, holding the short knife.

"Yes, this is a knife, but it hasn't been cut yet. As long as the knife is cut, this knife will definitely be a good knife." Said with a faint smile.

　　 Gao Niu is a person who likes weapons, even a silly head knows this. Now he saw a steel knife, it would be strange if he didn't like it.

　　 But obviously this knife can't be given to him. After this knife is cut, if there is no accident, it should belong to Leader Li Lei.

　　He is the leader of this tribe, so he naturally wants to have the best things, including weapons.

　　 But it doesn’t matter. This first successful smelting has given both Shixiong and the wood planer experience. If you start smelting with iron ore in the future, more steel will be produced. At that time, if Gao Niu likes delicate, then create a slender blood drink for him, and if he likes domineering, then create him a dragon slaying like a door plank!

　　 It’s really not good, and it’s okay to get him an eight-sided ruling rod!
