Taoism has not yet risen, Buddhism has not yet been introduced, and there is no custom of the Shangyuan Festival at this time, but everyone still delayed for a few days before rushing to Lingyang again, because Yu Zhou was busy making all kinds of utensils, and everyone's requirements were different. Pen % fun % Pavilion www.biquge.info

If you like to dance knives and sticks, you need knives, guns, swords, halberds, more practical requirements for pots and pans, and there is a shameless one, so he actually asked Yu Zhou to give him a bronze tripod, saying that he would pass it on as an heirloom from generation to generation......

In addition to all the unreasonable requirements, more than ten days of busyness tired him half to death, no one equipped with a bronze dagger, originally with Chen Ying's plan, since there are already people in the crowd who have ghosts, it is better not to give the blade again.

Yu Zhou rejected this request in front of everyone with a pleasant face, saying that it was better to have a self-defense weapon when he was out of the house, but he turned his face and handed the Changjun Sword into Zhong Liyi's hand again.

Zhongli, who had long known the inside story, did not show weakness, the dark long sword danced with a sneer, and the thick tree with the mouth of the bowl was cut off, which shocked everyone.

When everyone set off again, Yu Zhou gave Zhongli Han and Chen Ying a pair of leather armor respectively, different from the previous leather plate armor, the three pairs of inner armor are woven with leather ropes, and even mixed with some bronze filaments, and the chest is strengthened by heart guards, which looks cumbersome but light and abnormal.

has been getting along day and night for several months, and it is impossible for the strange thoughts of the people around him to hide from Lao Han, and the old guy said dissatisfiedly: "Baby, you just have too much thought, why is this." ”

"What did the father-in-law say, now that the Qin soldiers are pressing the border, maybe when the big war will come, with more protection, the child can rest assured in the mountains."

"Father-in-law, when you go out, you can't hurt people and have the heart to prevent people, if something goes wrong, destroy the mine, as long as people can come back, you can stay in the green mountains without worrying about no firewood."

After listening to Yu Zhou's words, Old Man Han didn't say anything, waved his hand and led everyone away.

After everyone left, the lively small village returned to calm, Yu Zhou's heart seemed to have been taken out, and he wanted to see what the mine was like in person, this year was also the node of Da Chu's rapid turn, compared with the thoughts of individual thieves, he was more worried about the Qin army that would immediately set foot in Chu.

I hope that my father-in-law will not be reluctant to mine the cave, forget it, there is still some time, Zhongli can come back from time to time, and then I will talk about it.

When the malt emerges, the eyes are full of emerald green is very gratifying, after a cold winter, many places in the house are creaking, the four houses are very easy to move, after a simple repair, Yu Zhou led the two sisters to live in Wei Zhe's room.

Zhongli was out of the house, Old Man Wei came back infrequently, he took the opportunity to wipe his nest with tung oil, and it was spring soon, and the beasts were afraid of the beast king's urine and did not dare to come, but all kinds of snakes, insects, rats and ants also came to the activity time.

These pervasive creatures are a nightmare of primitive life, and the pillars under the house can also be brushed with lime mortar, but the wooden hut can't do that, and the bright tung oil with a little rosin is both beautiful and insect-proof, but it doesn't smell good just after brushing.

said that he didn't move the copper ingot, Yu Zhouyan had a letter, because he had long been fed up with the soft copper, and the cast iron had accumulated a lot, he planned to start practicing, and the reason why everyone was staring at the copper was because this thing could not only cast utensils and weapons, but also an important circulation resource.

In other words, copper can be used as money regardless of whether it looks like money or not, and the copper ingots stored in the cave are tantamount to a mountain of gold and silver in the eyes of everyone, and iron will not be valued in this way.

But in Yu Zhou's eyes, the value of cast iron is much higher than that of soft copper, born in troubled times, wealth is only the source of disaster, hunger can not eat, thirst can not drink, everything you want to rely on your hands to create is true, as for how to defend their own achievements, of course, strength is respected.

Throughout the Cold Weapon Era, the development of iron tools has always been pivotal, because it is directly related to the strength of the country and the military. The entire history of human development is inseparable from this most common metal.

Although iron tools have begun to be applied, most of them are daily necessities, and the armaments are still mainly bronze, and the real large-scale popularization of iron tools is still after the Western Han Dynasty, and it is Yu Zhou's plan to be one step ahead.

It doesn't matter when he makes bronze, once he starts to strike iron, he doesn't allow anyone to come to the shack, first, the process is cumbersome and takes too long, the high temperature in the shack is not easy to bear, and secondly, this craft can be regarded as a secret art.

There are a lot of things to prepare, lime toner powder horse urine, etc., etc., and even in order to confuse the ears and eyes, Yu Zhou deliberately got some useless beast blood and animal bones.

Speaking of which, whether it is steel, pig iron or wrought iron, it is the same thing, the main component is iron, but because of the difference in carbon content, hardness and toughness are very different, and there is already a soft iron technique in the Warring States Period, which is often called wrought iron.

It's just that the ancients who did not have the support of chemical theory, the means of making steel were all based on the experience of skilled craftsmen, which was full of accidents and scarce production, and the carbon powder carburizing that they did not know was clear to Yu Zhou, and the quenching and tempering that they did not know was also understood.

It's easy to say, but it is explored step by step in China's long history, and once it is discovered, it will be treasured as a secret art, and it will never be passed on lightly until the moment of death.

The smelting of iron in the Warring States period was very simple, a furnace of molten iron was solidified, it was too soft, don't use it for anything else, it was too hard, then smash it! The hard smashing is suitable, and it becomes a weapon, the smashing is too soft, and then don't do anything else, and the process of smashing can be described as time-consuming and laborious, not to mention the thousands of hammers, there are very few craftsmen who can master it skillfully with experience.

Therefore, the output of steel is very small, and the softer soft iron is applied to weapons again, and it has to wait until the emergence of the steel filling method, of course, the great Chinese sons and daughters also have other means, such as the carburizing method and phosphorus powder smelting retrieved by Emperor Wu of the Han Dynasty from the Western Regions, which also made the iron forging more extensive.

In order to make the weapon more solid and tough, the iron structure is more complex, and the quenching and tempering annealing at different temperatures are more cumbersome, which is far from being clear in one or two sentences.

Our ancestors were industrious and intelligent, although compared with many ancient civilizations, China entered the Iron Age relatively late, but it was the fastest and most rapidly developing country, for example, China's block of iron originated in the sixth century B.C., 900 years later than the West, and the technology of smelting cast iron was 2,000 years ahead of Europe.

We only need a century of transition, and the West takes 3,000 long journeys.

There is so much nonsense, just for a sentence, every technological progress is standing on the shoulders of predecessors step by step, and some theories that later generations feel familiar with are tantamount to the existence of cheats in the eyes of the ancients.

Yu Zhou, who escaped from the gap between life and death, was the one who held the key, the key to alcohol was used by him to heal, and the key to the pulley was hit by him, and now in order to survive, he plans to open the secret of the iron weapon......
