Super Chief

　　 Kabulu's prestige is so high in the high tree tribe that even the tribe leader can't compare with it.

　　 Therefore, Hong Yun easily took three iron pots from the tribe.

　　Iron pan is the most common kind of cast iron pan, which makes Shi Xiong somewhat disappointed, but if you want to turn pig iron into steel, some preparations need to be done.

　　In this era, there are several best ways to turn a small amount of pig iron into steel, and the best way is to use the steel fry method or the crucible steelmaking method.

　　 The former was mastered by Chinese blacksmiths as early as the late Western Han Dynasty when it was 2000 years old. Europeans did not master this steelmaking method until the middle of the eighteenth century. As for the latter, it was only invented by the British not long ago, and it is estimated that it has not been promoted yet.

　　 However, no matter which method is used, a high-temperature crucible is needed to melt the pig iron. The crucible is easy to say, the southeast of Tennessee and the northwest of Georgia in the past are the largest kaolin producing areas in the United States.

　　With kaolin, a simple high-temperature-resistant clay crucible can be made, which can be used to melt pig iron.

　　 But if you want to melt pig iron with a melting point of more than 1,500 Baidu, you need the necessary fuel. It is obviously not feasible to use wood as fuel, and the temperature generated by the burning of wood cannot even soften the pig iron. Therefore, to melt these iron pots, Shi Xiong must find coal.

　　 However, the stone bear stayed in Knoxville for a few days before the soul passed. He knew that there were many small coal mines near Knoxville. Although the reserves were not large, they were all good anthracite.

　　 One of the coal mines is at the foot of a small hill about fifteen kilometers away from the Gaoshu tribe. When Shixiong went to the Great Smoky Mountains to play, he had seen this open-pit coal mine that had been closed for a long time. However, although the coal mine has been closed, the mine can still be seen.

　　 So Shi Xiong found a horse from the tribe, then took a bow and arrow and a bone spear, and then took the Kuaima to the open coal mine in memory.

The Appalachian Mountains that run through eastern North America are extremely rich in mineral resources. In this seemingly fragmented mountain range, there is a large amount of coal and iron ore. The reason why the United States was able to become The country with the highest output value in the world is basically the rich mineral resources contained in this huge mountain range.

　　 Although most of the coal and iron resources in the Appalachian Mountains are located in those areas in the north of Tennessee, there are also many mineral resources at the foot of the Great Smoky Mountains, but these resources are not as abundant as in the north, and large-scale mining is of little value.

　　 But for the Stone Bear and the little Gaoshu tribe, these resources are extremely abundant. Even if you look at the entire Cherokee family, these scattered resources are enough.

　　Walking eastward along the flat land in the valley, after walking out about fifteen kilometers, Shi Xiong saw the somewhat familiar hill.

　　 Just at the foot of this small hill with an altitude of no more than 300 meters, there is a high-quality anthracite open-pit mine. At the time, the **** of the Appalachian Frontier Museum said that this anthracite coal mine had been mined for decades. Before the 1950s, this coal mine was the largest open-pit coal mine near Knoxville. Most of the winter heating in Knoxville comes from this open-pit coal mine.

　　 Even though Kuaima didn't understand why Silly Head took him out in this season, he was still very happy. Being able to come out alone is a great thing for people of their age, even if Kuaima has already married, but he is only sixteen years old this year. In later generations, this is the age when you just entered high school.

"Stupid head, why are we here?" Although we respect the stupid head that has undergone tremendous changes, Kuaima still can't change her name to Shixiong. After all, the two of them are really the kind of being naked from childhood. When you grow up and grow up, the relationship is not ordinary closeness.

　　 Shixiong was not angry with this name of friend.

"I'm looking for a fuel that can not only keep warm, but also melt iron." As he said, Shi Xiong got off his horse, and after wandering around for a few laps, he stooped and picked up a piece of black hair. Bright stone.

　　 "I don't see it, what I need to find is this black stone." Shi Xiong raised the coal in his hand.

Hurry up and looked at the coal in Shixiong's hand, and said in surprise: "I have seen this kind of black stone several times. It can burn, but it produces poisonous gas and can kill people. My mother told me that this kind of stone is a devil. The excrement contains powerful evil."

　　 Shixiong rolled his eyes. This is the first time he heard that coal is actually the excrement of the devil. Isn't it a bit too big?

　　 But it is inevitable, let alone Indians, even the ancestors of China used coal as a real fuel after they discovered coal for thousands of years. Although the ancestors of China used coal to smelt iron as early as the Western Han Dynasty, heating was not used until a long time later.

　　 The carbon monoxide produced when coal is burned is indeed a toxic gas for the ancients who could not get rid of the smoke.

　　 It is inevitable for the Indians to treat coal as the excrement of the devil.

　　The ancients always named some unsolvable things or things in the name of gods or demons...

"Don't worry, UU reading www.uukanshu.com fast horse, this is a good thing. With this thing, we can smelt ironware by ourselves in the future, and it will be the moon of the long night (December) and the moon of the wolf (1 It’s best to use this to keep warm during the month).”

　　 In order to completely dispel Kuaima’s doubts and worries, Shi Xiong added: "This is what the supreme sun **** told me."

　　 This sentence is more effective than any explanation, and the worry on Kuaima's face is immediately gone.

　　 This area will become an open pit coal mine in 150 years, so the coal seam here is extremely shallow, and some coal blocks are simply exposed on the surface.

　　 Shi Xiong and Kuai Ma picked up for a long time before they picked up hundreds of catties of coal. After packing them with animal skin bags and tying them to the horse's back, the two men led the horses on the way back.

　　The horse is the most valuable property among the North American Indian tribes. At this time, no Indian was willing to ride a horse with more than a hundred catties on its back.

It is also a very tragic thing. North America originally lived with a large number of horses tens of thousands of years ago, but I don’t know how these horses disappeared in a short period of time. As a result, the Mongols passed the Bering Strait land bridge. After coming to America, I have not seen a horse.

　　 However, when European colonists carried a large number of horses to the other side of the Atlantic Ocean by ship, the horses became the most precious wealth and most loyal partner of the Indians.

　　 There are only more than 20 horses in the Gaoshu tribe, all of which are exchanged for the whites with various furs. The Cherokee people have not yet fully mastered their ability to train horses, so horses are very precious and precious treasures.

　　 If it weren't for Stone Bear to be the guardian of the Kabru Sacrifice, he would also not come to horses.
