Seeing that Wei Ba was silent, Wei Feng explained angrily: "Yang Yi, this fisher, thinks that he is a big surname in Xiangyang, and has always despised my Wei family as a martial artist, and has a lot of complaints about my father. He is now in the army in the Prime Minister's Mansion, responsible for the collection of grain and grass, and deliberately makes things difficult for his father with the origin of military affairs. If my father refuses to do it, it will be to obstruct the great cause of the Northern Expedition, and the prime minister will definitely not like it at that time. But how can we produce so much food in a hurry? That's why my father was angry about this......"

After listening to Wei Feng's words, Wei Ba understood a little bit that the contradiction between Yang Yi and Wei Yan had been going on for a long time. Although they are all from Jingxiang, the Yang family is a big surname in Xiangyang and has a profound heritage, while the Wei family is just a small strong man in Yiyang, and there is a blank in knowledge, and they started purely by military exploits, and the two families are not at the same level at all.

If Wei Yan admits intimidation, then that's fine, but Wei Yan is a master who is not convinced, and he doesn't take Yang Yi in his eyes at all, and there have been many conflicts, and the relationship is very stiff. Liu Bei died, and after Zhuge Liang came to power, Yang Yi joined the army as the prime minister's mansion. In the battle of Zhuge Liang's southern expedition to Hanzhong the year before last, he made great contributions to the transportation of grain and grass, and now he is the celebrity next to Prime Minister Zhuge Liang. Coupled with the banner of the Northern Expedition, it was not easy for him to give Wei Yan some problems.

There are now only four counties in Hanzhong, with less than 20,000 households, and even if the elderly and children are on it, it will not be able to solve the problem of food rations for more than 100,000 troops. Of course, transporting grain is unavoidable, but to transport grain from the Chengdu Plain to Hanzhong, the nearly thousands of miles of mountain roads are a big problem, so it is the best solution to solve as much as possible in Hanzhong, and the amount of this is in the hands of Yang Yi, as long as he moves, it is useless for Wei Yan to try, because you will definitely not be able to meet his requirements.

In other words, the initiative in this matter is all in Yang Yi's hands, and no matter how much effort Wei Yan spends, he can't complete the task.

Of course, Wei Ba can't, he is not an immortal, and it is impossible to become nothing. But he is not useless, he is learning agricultural machinery, firmly believe that the progress of tools is the sign of the progress of human civilization, he knows better what kind of impact a little improvement in tools may bring.

China has been a country with agriculture since ancient times, the development of agriculture has always been a major matter that the rulers must keep in mind, the development of agricultural machinery is the top priority, and there are many proud achievements in this regard. However, apart from those complex machinery, the simplest tools such as shovels and hoes were subject to smelting jishu and developed slowly. Until the middle of the Tang Dynasty, with the maturity of steelmaking, agricultural tools were changed from casting to forging, and tools such as hoes, shovels, and shovels could be made large and light, and really play a role. In the Han Dynasty, there were iron farming tools, but they were either very small and not applicable at all, such as the commonly used digging tools, which could only be made of wood as the main body, and only a piece of iron blade was inlaid on the top, or only one was the size of a palm, which was about the same as a spatula, otherwise it could not be moved, or it was large and heavy, and it could only be used with animal power. The ploughs of the Han Dynasty were pulled by two oxen, because the plough was too heavy, and the structure was not reasonable, and it was not good to break the ground.

To make the simplest analogy, a shovel is definitely more convenient than a wooden shovel, and two palm-sized shovels are definitely more efficient than a spade with only one palm-sized shovel, but if you use a cast shovel, two palm-sized iron palms can only be waved all day long if they are born with divine power, and ordinary people can't play a role at all, but it is not as practical as a wooden shovel with an iron mouth. In the past few days, Wei Ba has been running outside the city, and almost all the farmers he saw were turning the fields with wooden pads. He originally thought that there was some ancient style, not those antique goods in later generations who wore ancient clothes on the top and leather shoes were exposed underneath, but now when he heard Wei Feng complain, he suddenly thought of an opportunity to improve.

In addition to that, if the wooden shovel in the hands of the current farmer can be changed to a shovel for future generations, a farmer can play the role of at least two farmers, not to mention an increase of fifty percent, even if it is doubled, it is not a fantasy.

Wei Ba suddenly found that his major was useful for the first time. He laughed.

Wei Feng was scolding Yang Yi, and suddenly saw Wei Ba laughing, and he couldn't help but be a little inexplicable. He stopped talking and looked at Wei Ba puzzled: "Aba, what are you laughing at?" ”

"It's nothing, I just thought of a way to maybe help my father with this task."

Wei Feng's brows furrowed even tighter, and he stared at Wei Ba for a long time: "Really? ”

"Can I still lie to you?" Wei Ba grinned, and his mood suddenly improved. He patted Wei Feng on the shoulder: "Eat quickly, take me to a few blacksmiths after eating." ”

"Blacksmith?" Wei Feng was confused, but Wei Ba sold the guanzi, picked up the bowl and gobbled it up, and the wind swept away. Wei Feng saw it, smiled and shook his head: "Aba, it's the first time I've seen you eat like this, I'm really not used to it." ”

Wei Ba laughed twice in disguise, and quickly swept away the food in front of him, only then did he wipe his mouth and burp. Wei Feng had something in his heart, and when he saw that Wei Ba had eaten well, he also put down the bowl and pulled Wei Ba away. When Wei Wu saw this, he hurriedly followed, following behind like a fart.

Wei Ba followed Wei Feng out of the county temple gate and came to Tiezuo, Wei Feng found a dark-faced old master and pointed at Wei Ba: "You listen to him, what he teaches you to do, you do it, do you hear?" ”

The old master grinned, revealing the few yellow teeth left, and the wrinkles on his face were crowded even more densely. He bent his waist and said respectfully to Wei Feng: "No, young general, the old man must be attentive." ”

Wei Ba is a little unaccustomed, although he is not a safflower boy who loves five stresses, four beauties and three loves, but he still has the habit of respecting the old and loving the young. He smiled and arched his hand a little rustily: "Master, I want to ask you to help me build a thing, and I also ask the master to help." ”

When the old master saw Wei Ba saluting him, he was startled, and he didn't ask if the ground was dirty or not, and knelt on the ground with a plop, which startled Wei Ba. Wei Feng raised his eyebrows, a little displeased: "Aba, he is an official slave, you are so polite to him, he can't stand it." ”

Wei Ba was a little embarrassed, and then he realized that craftsmen in these years were lowly workers, not the working class of later generations, not to mention that they were official slaves who did not even have personal freedom. He coughed, didn't make much fuss about etiquette, and told the old man his intentions succinctly.

The old man looked respectful at first, but he was a little indifferent, almost sluggish, and then when he heard Wei Ba talk about the steelmaking technique of pig iron and wrought iron mixing, his eyebrows and eyes began to become vivid, and he was a little impatient, and his eyes looked at Wei Ba with a little more awe.

In fact, Wei Ba didn't say anything, just told him some steel filling methods. The irrigation method was probably invented in the late Han Dynasty and the early Jin Dynasty, and the Northern and Southern Dynasties had already used the steel filling method to create agricultural tools, and there was no difficulty in jishu, but some improvements were made in the current repeated folding and forging method. The most sophisticated weapons in the late Han Dynasty were made by folding and forging multiple times, removing the impurities in the pig iron and turning it into mature iron, and then quenching it to increase the hardness of the blade, so as to achieve the overall flexibility and sharp edge. It's just that this method is very labor-intensive, and it is only used to build weapons, and it has not been used to build agricultural tools. The characteristic of the steel filling method is that the iron quality of pig iron is improved by adding wrought iron, and the so-called suzuku iron is made, which reduces man-hours and improves efficiency.

The master has been fighting iron all his life, and it is easy to understand the essence of it. Wei Ba drew another picture for him at any time, and the master took the drawing and left happily. Wei Feng frowned and pulled Wei Ba aside: "Aba, do you need to use a lot of iron for this object you made?" The big war is coming, the iron is very nervous, and if it is used too much, it will not work. ”

Wei Ba said with a smile: "What are you in a hurry, tomorrow morning, tomorrow night, you can see things, and then you will know how much iron you will use?" ”

Wei Feng glared at Wei Ba for a long time, and smiled helplessly: "Stinky virtue, keep it secret from me." Okay, I won't ask, I'll see when the time comes, if you do a good job, then of course, of course, I will tell my father and let him reward you. If you don't do it well, hehe, I'll tell my father too, see if he doesn't beat your ass and bloom. ”

Wei Ba rolled his eyes, Wei Wu said during the day that Daddy Wei Yan would beat his ass to bloom, and now Brother Wei Feng said so again, could it be that his ass used to bloom often? This dad is a bit violent, no wonder he looks at him, his heart is furious, it turns out that this fear has invaded the bone marrow and has become instinct.

Alas, how can I have a wolf father.

……

When he got up the next morning, Wei Ba got up from the hot, soft bed with great perseverance and began his masochistic morning exercise again. Since he started exercising, his sleep has become very good, basically a pillow, insomnia and other petty bourgeois problems are completely gone, of course, getting up in the morning has become more difficult, and it always takes more effort to pull himself out of bed.

When Wei Ba and Wei Wu ran a lap from the mountain, the sun had already risen high. Because of something in his heart, Wei Ba didn't stay on the mountain for more, and went straight back to the city, and as soon as he entered the door, he saw Wei Feng holding a freshly made haode shovel and smiling, smiling with a spring breeze on his face. The old master stood in front of him with his waist bowed, his face full of pride and anticipation of the reward.

Seeing Wei Ba coming in, Wei Feng beckoned again and again: "Come on, come on, look, according to your method, you just built Haode Tieji." ”

Wei Ba walked over, took it and checked it, and felt that it was still a little heavy, it seems that this master is playing for the first time, and his skills are not very proficient, and some places are still too thick.

"It's too heavy." Wei Ba frowned slightly, "Master, can you fight softer?" ”

"No problem, no problem." The old master grinned toothlessly and nodded again and again: "This is the first one, the old man is not very proficient, and it is estimated that he can lose a lot when he fights again." Well, I don't dare to say more, it's always okay to subtract two or three percent. ”

Wei Ba turned his head to Wei Feng and said, "Brother, look...... Does it work? ”

Wei Feng thought that Wei Ba was making him happy, so he didn't care, and laughed loudly: "Stinky boy, his heart is quite small." No problem, let alone another two or three percent, even if it is now, it is not a big problem. Well, I want to hit a hundred first, let people try it, see if it's practical, if it's really good, I'll play some more, it will help somewhat. ”

Wei Ba smiled but said nothing. How much helps? Don't you know, although this thing is small and jishu is not complicated, it may be an epoch-making beginning.

At least, it's a start for me in this era. ————
