Seeing Wei Ba silent, Wei Feng explained angrily again: "Yang Yi, this young man, thought he was a great surname in Xiangyang, and he always despised my Wei family as a military man, and he had many complaints about his father. He is now a military officer in the Prime Minister's Office, responsible for the raising of food and grass, and deliberately made things difficult for his father with the grounds of military and national affairs. If his father refused to do it, he would obstruct the great cause of the Northern Expedition, and the Prime Minister would definitely not be happy at that time. But how could he produce so much food in anger? His father was so angry about this..."

After hearing what Wei Feng said, Wei Ba understood a little bit. The conflict between Yang Yi and Wei Yan had a long history. Although they were both from Jingxiang, the Yang family was a big surname in Xiangyang and had a deep foundation. The Wei family was just a small powerful man in Yiyang. His knowledge was blank and he started his business purely by military achievements. The two families were not on the same level at all.

If Wei Yan admits his defeat, that's fine. Wei Yan is a dissatisfied lord and does not take Yang Yi seriously at all. He has had many conflicts and his relationship is very stiff. After Liu Bei passed away and Zhuge Liang was in power, Yang Yi became the Prime Minister's Office to join the army. In the battle of Zhuge Liang's southern expedition to Hanzhong the previous year, he prepared food and grass and made great contributions. Now he is a celebrity around Prime Minister Zhuge Liang. In addition to the banner of the Northern Expedition, it is not easy for him to give Wei Yan some difficult problems.

There are only four counties in Hanzhong now, with less than 20,000 households. Even if the elderly and children are all in the process, they cannot solve the food problem of more than 100,000 troops. Of course, it is inevitable to transport grain, but if you have to transport grain from the Chengdu Plain to Hanzhong, the nearly thousand-mile mountain road is a big problem, so solving as much as possible in Hanzhong will become the best solution. The amount of this is in Yang Yi's hands. As long as he moves his pen, it will be useless to work harder, 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 spent, he could not complete the task.

Of course, Wei Ba cannot. He is not a god and cannot become inaction. But he is not useless at all. He is learning agricultural machinery and believes that the progress of tools is the symbol of the progress of human civilization. He is more clear about the impact of some improvements in tools.

Since ancient times, China has established a country with agriculture. The development of agriculture has always been a major event that rulers must take care of. The development of agricultural machinery is the top priority, and there have been many impressive achievements in this regard. However, aside from those complex machinery, the simplest tools such as shovels and hoes were restricted by smelting technology and developed slowly. Until the middle of the Tang Dynasty, with the maturity of steelmaking, agricultural tools were transformed from casting to forging, hoes, shovels, and shovels to make them big and light, and truly play a role. There were iron farm tools in the Han Dynasty, but they were either very small and not applicable at all. For example, the commonly used trunks could only be made with wood as the main body, with only an iron blade on the top, or they were only made as a palm-sized, similar to a spatula, otherwise they would not be able to hold them, or they would be large and heavy, and they could only use animal power. The plows in the Han Dynasty were pulled by double cattle because the plow was too heavy and the structure was not reasonable, and it was not good to break the ground.

To give the simplest example, shovels must be more convenient than wooden bods. Two shovels as big as palms must be more efficient than shovels that are only the size of one palms. However, if a cast shovel is used, two iron palms as big as palms can only be swung for a whole day. Ordinary people cannot play a role at all, but are not as practical as wooden bods with iron mouths. In the past few days, Wei Ba was running outside the city, and almost without exception, the farmers he saw used wooden bods to turn over the fields. He originally thought there was a bit of an ancient style, not an antique product in later generations who wore ancient clothes on top but had leather shoes exposed below. Now, when Wei Feng complained, he suddenly thought of an opportunity to improve.

Not to mention, if the wooden trunk in the current farmer's hand can be changed to a shovel used in later generations, a farmer can play the role of at least two farmers, let alone increase it by 50%, even if it doubles, it will not be a matter of day and night.

Wei Ba suddenly realized that the major he studied had a place to use for the first time. He laughed.

Wei Feng was scolding Yang Yi, but suddenly he saw Wei Ba laughing, and he couldn't help but feel a little confused. He stopped talking and looked at Wei Ba in confusion: "Aba, why are you laughing at?"

"Nothing, I just thought of a way, maybe I can help my father complete this task."

Wei Feng frowned even more, staring at Wei Ba for a while: "Really?"

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

"Blacksmith?" Wei Feng was confused, but Wei Ba kept it in a silence, picked up the bowl and swallowed it voraciously, and the wind swept the clouds. Wei Feng looked at it, smiled and shook his head: "Aba, the first time I saw you eating like this, I really feel a little uncomfortable."

Wei Ba smiled twice in concealment, quickly swept the food in front of him, and then he burped his mouth. Wei Feng had something to do in his mind, and when he saw that Wei Ba had finished eating, he put down the bowl and pulled Wei Ba away. When Wei Wu saw it, he hurriedly followed, following behind like a follower.

Wei Ba followed Wei Feng out of the county temple gate and came to Tiezuo. Wei Feng found a dark-faced master and pointed at Wei Ba: "You listen to him, you can do whatever he teaches you, do whatever he teaches you, have you heard?"

The master grinned, revealing the few yellow teeth left, and his face was filled with wrinkles like a knife, squeezed even more densely. He hunched his waist and said respectfully to Wei Feng: "No, Major General, I must take my heart."

Wei Ba was a little uncomfortable. Although he was not a red flower boy who loved five talks, four beauties and three loves, he still had the habit of respecting the elderly and loving the young. He smiled and bowed in a little unfamiliar way: "Master, I want to ask you to help me create something, and I also ask the master to help me."

When the master saw Wei Ba saluting him, he was startled. He didn't ask if the ground was dirty or not. He knelt on the ground with a thump, which scared Wei Ba instead. Wei Feng raised his eyebrows and felt a little unhappy: "Aba, he is just an official slave. You are so polite to him that he can't stand it."

Wei Ba was a little embarrassed, and then he realized that craftsmen were a cheap business these days, not to mention that they were official slaves who did not even have personal freedom. He coughed, did not make more polite etiquette, and told the old man concisely about his intentions.

The old man looked respectful at first, but was a little indifferent and almost dull. Later, when he heard Wei Ba talk about the steelmaking technique of mixing pig iron and cooked iron, his eyebrows and eyes began to become vivid, and he couldn't wait. His eyes looked at Wei Ba with a little awe.

In fact, Wei Ba didn't say anything, but just told him some steel filling method. The steel filling method was probably invented in the late Han Dynasty and early Jin Dynasty. During the Southern and Northern Dynasties, it was generally made by the steel filling method to build agricultural tools. There was no technical difficulty. It was just a little improvement in the current repeated folding and forging method. The most exquisite weapons in the late Han Dynasty were used to remove impurities in pig iron into cooked iron, and then quenched to increase the hardness of the blade to achieve the effect of overall flexibility and sharpness of the blade. However, this method is very labor-intensive and is only used to build weapons, but has not been used to build agricultural tools. The characteristic of the steel filling method is to use the addition of cooked iron to improve the iron quality of pig iron, make the so-called iron, reduce working hours, and improve efficiency.

The master had been fighting iron all his life and could easily understand the essence of it. Wei Ba drew a picture for him at any time. 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 battle is about to be, and the iron is very nervous. If you use too much, it won't work."

Wei Ba said with a smile: "Why are you in a hurry? So soon tomorrow morning, then tomorrow night, you can see things. Wouldn't you know how much iron you'll use?"

Wei Feng glared at Wei Ba for a while, and smiled helplessly: "Strange virtue is kept secret from me. Well, I won't ask you anymore. Let's see if you do well. If you do well, of course there is no need to say. I'll tell my father and let him reward you. If you do not do well, hehe, I'll tell my father, see if he won't beat you up."

Wei Ba rolled his eyes. Wei Wu said during the day that his father Wei Yan would beat him up and make his butt blossom. Now his brother Wei Feng said this again. Could it be that his butt blossomed in the past? This father is a bit violent. No wonder he felt a little scared when he saw him. It turned out that this fear had infringed on his bone marrow and became an instinct.

Alas, why did I get a wolf dad?

...

When he woke up the next morning, Wei Ba used his incomparable perseverance to get up from the warm and soft bed, and once again started a self-abuse morning exercise. Since he started exercising, his sleep has become very good. He basically just touched his pillow, and petty bourgeois problems such as insomnia have completely disappeared. Of course, it has become more difficult to get up in the morning. He always has to put more effort into pulling himself out of the bed.

When Wei Ba and Wei Wu ran around the mountain, the sun was already high. Because there was something in mind, Wei Ba did not stop on the mountain for more time and went straight back to the city. As soon as he entered the door, he saw Wei Feng laughing with a newly built shovel, smiling with a spring breeze on his face. The master bent down and stood in front of him, full of pride and expectation for rewards.

Seeing Wei Ba come in, Wei Feng waved his hand repeatedly: "Come on, come on, look, follow your method to create the iron mattress."

Wei Ba walked over, took it and weighed it, and felt it was still a bit heavy. It seemed that this master was not very skilled in the first time he was working on it, and some parts were still too thick.

"It's too heavy." Wei Ba frowned slightly, "Master, can you beat it lighter?"

"No problem, no problem." The master grinned with his toothless mouth and nodded repeatedly: "This is the first move. I am not very skilled yet. I guess I can reduce it a lot when I hit it again. Well, I dare not say that if I have too much, it is always OK to reduce it by 20% or 30%."

Wei Ba turned his head and said to Wei Feng, "Brother, you see... can it be used?"

Wei Feng thought Wei Ba was making him happy and didn't care. He laughed loudly and said, "You guy, you're pretty stingy. No problem, don't say you'll lose another 20% or 30%. Even if it's like this, there's no big problem. Well, I want to hit a hundred first and let someone try it out to see if it's practical. If it's really useful, I'll hit more, which is somewhat helpful."

Wei Ba smiled without saying a word. Something helps? You don’t know that although this thing is small and not complicated, it may be an epoch-making beginning.

At least, it was the beginning of my time.———
