Seven days later, in Zhongnan Academy, Li Wanping came from Chang'an to look for Bai Fan.

"Husband, didn't you just make pranks against them once? As for you so worried and hiding in the academy and never going out again, what are you doing?"

As he said that, Li Wanping took out his handkerchief and came forward to wipe the dirt on Bai Fan's face. At this time, Bai Fan's face was covered with sweat and black ash, and his hair was messy. It was obvious that he had not been cleaned up for several days.

Bai Fan took a handkerchief and wiped his sweat and said with a smile: "Why do you really want to hide from them? I'm not going to plant fairy grains? I'm about to plant food? I'm about to get the farming time in the field. I need to make an urgent tool, otherwise the breeding matter will be difficult to deal with."

"What kind of magical artifact is it? Isn't it enough to find someone to come and leave it to them for planting? What? Do you have special requirements for fairy grain?" Li Wanping was puzzled.

Bai Fan smiled and said, "How many people should I find to farm in Chang'an County with a hundred thousand acres? Once there are more people, there is no guarantee that there are any spies in the enemy country. So in order to solve this problem, I can only find a way to reduce labor.

Farmers only find three thousand reliable people to farm, but if we want to make three thousand people successfully cultivate 100,000 acres of land, we have to rely on our magical artifact."

"Oh? What kind of magic weapon is so powerful? Can three thousand people cultivate 100,000 acres?"

"Haha, in fact, with this thing, let alone three thousand people, each person can take care of at least a hundred acres of land. Three thousand people are for maintaining intensive cultivation, after all, it is breeding of fairy grains."

ah???

Li Wanping was frightened and wanted to go and see what treasure it was, but was told that the blacksmith workshop was dirty and messy, and the artifact had not been prepared yet, and it would take three days.

It is not surprising that Li Wanping was surprised. Although farmers were careful to serve the fields during the Tang Dynasty, due to backward equipment and limited manpower, a strong worker could be responsible for five to ten acres of fertile land. For example, Bai Fan's father Bai Da said it was 200 acres of fertile land, but how much could he plant? Many fields were plowed shallowly, sow seeds, and wait for the next year to make do with the cost. Only a few acres of land are actually made for food.

This was rewarded by Bai Da. Most ordinary people in the Tang Dynasty had little land and were not rich. Many of the land were still in the hands of various nobles. Although the people could open up land, the newly reclaimed land had not been harvested for three years, and there was no wasteland a few acres a year. Therefore, the overall life of the people in the Tang Dynasty was relatively difficult.

"Madam, why are you free to come to the academy? How many children in the family are pointing at you to discipline them."

Thinking of the four naughty boys in the family, Bai Fan and his wife laughed at the same time. The four children are only three years old and are already lawless in the Bai Mansion. But Bai Fan dares not discipline them severely. The four boys are really the flesh of Bai Fan’s seventh uncle. When they see their father Bai Fan’s bad expression, they hide from Zhang Qi. Every time Bai Fan is scolded. If this continues, the children actually enjoy pranking their father.

"It's the children's turn to discipline my sister Ying'er, and I can't stand it even if I come, so we both took turns to take care of it.

Actually, it’s nothing to do when I come to you, but my father always comes to you, but you are not here. I heard it’s for the peppers.”

Bai Fan was speechless, "Tell me, you're so scrupulous. Didn't I just mess with him once? As for complaining to you every day?"

Li Wanping smiled and said, "It's not because of this, so are you. The son-in-law punishing his father-in-law. Now this matter has been spread throughout Chang'an, and the father has no shame to go out.

He came to you, and I heard that my mother learned the deliciousness of peppers from my second aunt, and she pestered her father to ask you to make a meal. I just happened to want to have another meal of oil splashed noodles..."

"Didai, don't know you yet? Actually, my father-in-law is greedy and wants to take the opportunity to call me to take revenge. Go back and tell him that when I finish breeding fairy grains, I will serve him well for a few days and be a chef for a month. Don't hold on all day."

Bai Fan didn't know what Li Wanping said when she returned to her parents' home. Anyway, the next day, Emperor Li Er and King Jin Li Jiancheng came together and plunged into the secret casting workshop of Zhongnan Academy.

"Art? Where is the artifact?" Before entering the door, Li Er started shouting.

Everyone inside was busy making irons, who had the ability to deal with him?

The Li brothers saw that the casting workshop was filled with various iron tools of all sizes, and were surprised to pick them up and examine them one by one.

"This is Qianliang Stainless Steel? All are Qianliang Stainless Steel?"

"This thing is a farming artifact?"

The Li brothers exclaimed, causing everyone in the foundry to burst into laughter.

Qin Qiong, who was in charge of pulling the bellows, smiled and said, "That's just various parts. Jian Zhi said that he would form a huge mechanical beast in the end, and he would have the strength of at least fifty horses. The advantage is that he doesn't have to stop and rest."

"real?"

"There is really such a thing. How many acres of land can be cultivated on that day? Son-in-law, seeing that you are so confident, you must do more, which can greatly alleviate the problem of insufficient oxen in the Tang Dynasty. I am very happy, very happy!" Li Jiancheng also nodded.

No wonder the Li brothers rushed over excitedly. You should know that in ancient times, there were limited numbers of oxen and horses to cultivate, and war horses were not used for farming. The fields were all oxen, horses, mules, and donkeys, and these were also very expensive. In the current economic situation of the Tang Dynasty, although there were cattle imported from Shiwei, it still could not be popularized to the extent of each household and oxen.

Even if a cow is a family, it is a great achievement to plow two acres of land a day, because the cattle are livestock and they have to rest and eat grass. When two acres of land a day, the people who command the plowing land cannot stand it, so this matter greatly restricts the development of agriculture.

It is conceivable how many people are needed to cultivate 100,000 acres of land? How many cattle are needed? How much investment is needed to solve the problem of turning over and breeding fairy grain?

Bai Fan's requirements are higher. When breeding fairy grains, the fields must be deeply cultivated, which should be doubled than the farming depth of ordinary people. Because the people of the Tang Dynasty now plow the soil and eat the soil too shallow, it is only five fingers deep, but how can you double the depth of eating the soil? Wouldn't you be exhausted? So in the end, Bai Fan can only find a way to solve it himself.

Bai Fan explained while keeping hammers in his hand, "Father-in-law, please spare me. This thing has thousands of parts of size. I originally planned to use the mass production of the Datang blast furnace when it was built and could produce stainless steel. However, it was obvious that 30% of the blast furnace was not completed, and it would take at least three months.

So I had no choice but to use the ancient casting method to temporarily create a set by hand. If an ordinary blacksmith makes it, although the parts are the same shape, the texture will be much worse. I am afraid it will be broken as soon as I use it. I made this Ouye casting technique, and the strength of each part can match the legendary magic weapons.

It takes ten days to build it. On average, a few of us need to make hundreds of parts day and night every day, and it still needs to be done. This task, unless I have the eyesight, no one else can do it."

Bai Fan didn't talk nonsense about this because he had the ability to have the ability to make the ruler and rule. Whether these parts can be used in accordance with the specifications, can you tell at a glance that it is absolutely impossible to change someone.

For this thing, Bai Fan found a lot of helpers, all of whom were masters, including Ziyang Zhenren, Li Yuanji, Qin Qiong, Li Yuanba, and Yuchi Baolin. Among them, only Bai Fan and Li Yuanba were proficient in hammering techniques, while Yuchi Baolin threatened to inherit his ancestral property (Yuchi Gong was a blacksmith), and wanted to learn casting with his master Bai Fan. Seeing that he was born with great strength, Bai Fan simply passed on his Ou Ye casting technique. As for the others, they were all helpful. After all, ten days of hard work are not something that ordinary people can withstand.

Li Er nodded in admiration and asked, "Well, the magical artifact is naturally not so easy to create. By the way, what is the name of this thing?"

Bai Fan smiled and said, "He has a simple name, called 'tractor', which means a machine specially used for dragging, and its nickname is Tie Niu."

Yes, you read that right, it’s just a tractor. The times are developing and the country is progressing. The Tang Dynasty is about to start a black-hailing technology era. Don’t say that the starting point is too high. It has nothing to do with a steam engine. Tractors are nothing. There is a complete manpower, material resources and technology. With a library in hand, what’s wrong with building a high place? So stay tuned~
