Super Chief

　　 Shi Xiong discovered that he had really underestimated the North American Indians of this era before.

　　 Before, in the eyes of Stone Bear, whether it is the Gaoshu tribe or other North American Indians, they are similar to the nomads of the ancient North China, backward and ignorant. But just now, what happened under Shi Xiong's eyelids made Shi Xiong fully realize that he was wrong before, and it was quite wrong.

It turns out that although the North American Indians of this era are ignorant and backward, they are actually very smart. They are very good at summing up various experiences in life, and they use lithographs or tether knots to record this experience. Let future generations avoid detours.

　　 The trunk of this big oak tree that has just been stripped completely weighs absolutely more than 10,000 catties. If the stone bear is allowed to transport the wood down the mountain, he will really be blinded.

　　 But it took less than two hours for a group of people headed by Old Wood. This big log that made Stone Bear a little helpless was transported to the bottom of the mountain.

　　The method is very simple, it is the most primitive rolling wood...

　　While Shi Xiong touched his chin and wondered how to transport this large log down the mountain, a group of tribesmen led by the old wood made a lot of two to three meters long and thin thigh thick logs. Some of these rolling logs were just picked from the branches of this big oak tree, and some were carried by the tribe from the tribe when they returned to the tribe.

　　 These guys first tied one end of the tree trunk with a rope, and then adjusted the direction of the big tree trunk together, and then put a log underneath and started to push it. Push a little distance and place the second and third logs.

　　 Even if this heavy trunk presses some of the log into the soft soil, the log still exerts its due effect.

　　 Just like this, when the big tree trunk rolls faster and faster, it will use inertia to rush down the mountain for a long distance. After the tree trunk was blocked by the soil, a group of tribesmen began to repeat the previous work under the command of Old Wood.

　　 In this way, using rolling logs section by section, this big tree trunk weighing tens of thousands of catties was forced to the bottom of the mountain by these tribesmen in a way similar to a relay...

　　 It’s not enough to get to the bottom of the mountain. There is still a little distance from the tribe here. At this time, you can’t use the rolling method. After all, there is no gap between here and the tribe.

　　 But these people still can't help it. More than twenty tribesmen quickly returned to the tribe. When they came back, one of them was holding a tamed bison...

　　 If this big tree trunk is dragged by humans, it is estimated that at least it can be dragged by dozens of holes. But changing to a tamed bison is different. These tall and strong guys are really powerful. Twenty bison’s towing kits are tied with long ropes, and the back is connected to the big tree trunk, and then twenty cows move forward together. The root of the big tree trunk was easily pulled.

　　 And the advancing speed of the bison was just as fast as the speed at which the tribes could replace the rolling logs. In this way, in just tens of minutes, the big log was transported to the clearing in the middle of the tribe.

　　 Then there was Shi Xiong who was ashamed of the backwardness and ignorance of these people.

　　 Through this incident, if anyone dares to say that his people are stupid in the future, Shi Xiong promises a big ear scraper to instigate it...

　　 The big trunk is shipped here, everything is easy to say.

　　 Build a shed, this is the first thing.

　　 The location of this tree trunk will be the oil press in the tribe from now on, so a shed or wooden house with a large enough area must be built here. At least it can accommodate this big tree trunk and the surrounding cooking equipment.

　　 Building a shed or a wooden house does not require Shixiong to worry about it, nor does the old wood and the family worry about it. The old wood can grab a junior at random and can lead the tribe to build the shed or wooden house.

　　 The old wood family will be under the guidance of Shixiong during this period of time to do a good "plastic surgery" on this big tree trunk...

The stone bear uses this big tree trunk as an oil press, so it takes such a lot of effort to cast a double-handed saw, cut the tree, and get this big wood weighing ten thousand kilograms here. .

　　 Yes, without a modern oil press, Shixiong can only use the old-fashioned wedge oil press that the Chinese ancestors have used for thousands of years to press oil.

　　Past life Shixiong was born in his hometown in 1983. He has been living in his hometown when he was a child and when he was in middle school. In the 1990s, the only oil press in that small mountain village was still using the oldest wedge oil press to extract oil for the villagers and the surrounding villagers.

　　 And the owner of this oil mill is Shi Xiong's fourth grandfather.

　　 So when I was young, Shi Xiong played in the oil mill or helped. When I was a child, I played there because there are countless leftovers. A group of children can dig holes in it. The most important thing is that the smell in the oil mill is very good, and the stone bear especially likes it.

　　 After going to middle school, Shi Xiong would come to the oil press at the Fourth Grandpa’s house to help every summer and winter vacation. If you helped a day at that time, Grandpa Four would give you two yuan, and he would also take care of a meal at noon. This is not a small income for the Shixiong family, whose family conditions are not very good...

　　 So ~www.readwn.com~ For the wedge oil press in Grandpa Fourth's house, Shixiong couldn't be more familiar with it.

　　 The wedge oil press of the fourth grandfather of Shixiong is made of an old locust tree trunk with a length of four meters and a diameter of a little over one meter.

The trunk that 　　 Shixiong got is a bit shorter, but it's not a big problem. However, this trunk is much thicker than the trunk used in Grandpa Fourth's oil press, so the oil cake compartment can be made bigger by then.

The structure of this wedge oil press is actually very, very simple. The press body of the entire oil press is this large wooden column; on the side of the press body, a two-and-a-half-meter-long rectangular wooden trough will be excavated. This rectangular wooden trough is the press. Bed; a circular groove is cut in the middle of the press bed with a diameter of about 70 cm or larger. This circular groove is the oil cake compartment, and there will be several small holes under the oil cake compartment, which are the oil leak holes.

　　 The entire press is composed of a rectangular squeeze chamber and a circular oil cake chamber.

　　 When using this original oil press to press oil, first fill the oil cake compartment with crushed oil cakes, and then stuff wood blocks from the squeeze compartment on the right side of the oil cake compartment, which is also full. When the wood blocks and oil cakes are all stuffed up and squeeze it up, then smash the triangular wooden wedges from the gaps in the wood blocks.

　　As the wooden wedges continue to smash in, the wooden pieces will become tighter and tighter, and by the way, the oil cake in the oil cake compartment will become tighter and tighter.

　　 If one wooden wedge is not enough, use two wooden wedges.

　　 When the wooden wedges are smashed in more and more, under the huge pressure brought by the wood, those oil cakes will begin to seep out.

　　This is the working principle of the wedge oil press. And because the wooden wedge plays a key role in the entire oil pressing process, this very primitive oil press is named the wedge oil press...
