Li Dejian pointed to the first picture.

"This is a sketch of the shape of the machine, according to the regulations of the original ghost labor valley, the working principle of the machine, the internal structure and everything else is top secret, and it is not allowed to be passed on without a holy order."

"This machine has only one purpose, and that is to provide power. Tremendous momentum. ”

After Li Dejian's explanation, Yao Silian, the secretary of the Ministry of Industry, asked: "How to explain the power at one time?" ”

The word power has been around for a long time, but Yao Silian wants to hear about whether the power provided by this machine is the same as the power he understands.

"The wind blows the sails, and the boat with a drive is the power. People pull the car, and people bring power to the car. Horse-drawn carts, water-driven waterwheels, all this is called power. ”

Yao Silian looked at the other important ministers, and after everyone nodded, Yao Silian said, "Please continue." ”

"The machines provide power, and everything that needs power can be done. For example, in the past, the yarn mill used a waterwheel, and in winter, the water mill would increase the animal power to drive the turntable, and this machine is now divided into several different sizes, one type is equivalent to the strength of twenty horses, small size, light weight. ”

It seems that there are many different kinds of things, and the courtiers are interested.

Li Dejian quickly drew a strange picture.

"This is a willow horse design, and there is already a finished machine, and there are many problems, and there are hundreds of things that need to be improved. There are hundreds of parts that need to be adjusted. This thing is called the Iron Ox, and the willow horse must be able to be used within one year and complete mass production within two years. ”

"What's the use of the Iron Bull?" Li Shimin was also aroused.

Li Dejian turned around and bowed slightly: "Sage, Liu Juma has established thousands of hectares of huge farm areas in the Huashan area. Two people and one cow, can cultivate four acres of land a day is already the limit, to borrow the words of the willow horse, if you cultivate five acres, people are not tired of cattle are also tired. ”

Li Shimin and the ministers all laughed, and the high-ranking officials of the Tang Dynasty also understood agriculture to some extent.

In fact, three acres a day is already a high work efficiency.

"It doesn't matter how much charcoal an iron ox eats every day, the important thing is that it is estimated that a type of twenty horsepower iron oxen can plough about fifty times more fields per day than two people and one ox. However, small plots of land cannot be cultivated, and large areas of fields on the plains that are joined together are required. ”

"Right now, the Ghost Worker Valley has mobilized two ghost workers and sixteen skilled craftsmen. as well as six farmers and four well-educated people. After checking many ancient books, I hope to build a columbus that works with the iron ox within a year. ”

This thing existed as early as the Eastern Han Dynasty.

Among them, six people, two oxen and six feet cocooned, reaching the record of sowing 25 acres in one day.

The courtiers present, especially the civil ministers, if they have not heard of this, can basically be dismissed.

Therefore, Li Dejian did not explain the cocoon again, but said: "According to the design of the willow horse, an iron ox should be able to make a deep plow and bottom fertilizer at the same time, and sowing seeds can be completed at one time. The first type of iron ox can complete at least 200 acres of work per day, and the second type of 60 horsepower iron cattle should reach the volume of 1,000 acres. ”

It's powerful.

Even Li Shimin was moved.

Li Dejian continued: "Liu Juma instructed that the first type of iron ox must be finalized within a year this year, and formal production can begin. Tomorrow, when spring begins, four formed iron oxen will be prepared for spring ploughing. Next year, 30 iron oxen will be manufactured to be used in Luoyang's millions of acres of cultivated land. ”

Luoyang's million-acre granary plan, Datang has not yet officially established the project.

The difference is in the poor manpower.

There were too many dead people in the war in Luoyang, and it was a large plain area, the land was vast and sparsely populated, and the countless fields under it were barren.

"Minister, support the Luoyang granary plan." The Ministry of Household and the Ministry of Industry expressed their support at the same time.

If it can really be 100 acres a day, then the fertile fields in Luoyang that are barren because of the lack of people can be used again.

Li Dejian said: "Iron Ox Type 1 is also divided into three categories: Iron Ox Type A, Iron Ox Type B, and Iron Ox Type C. ”

"We tried it in Huayuan, and although it only took less than a mile of digging to break down, the design direction was not wrong. You can dig half a foot at a time, or shovel the soil by manpower, or you can use the iron ox type C to push the soil aside. It only takes ten days to dig a canal that is one mile long, one zhang wide and four feet deep. Next, send someone to repair the embankment. ”

Powerful, too powerful.

Li Shimin only thought about one thing in his head, if his cousin had this machine, it was estimated that what he would have to build would not be the 4,000-mile canal, but the 10,000-mile canal.

However, Li Dejian didn't mention the steam engine at all, only the machine.

Li Shimin understands that the steam engine is estimated to expose the core technology of this machine, so he is also thinking about what kind of name is better.

Li Dejian quickly erased the handwriting on the blackboard.

He wasn't going to say that Iron Bull Type 2, Type 3 and the like were things that he couldn't do in a few years.

After reaching the Iron Bull III and becoming proficient, it is possible to build a real train.

At the moment, there can be a train, and the Iron Ox can be pulled, but there is no point in pulling one or two carriages and slowing down. So Li Dejian will not mention half a sentence.

Li Dejian drew another picture: "This one is more bulky, but it is easier to make than the Iron Bull." The Iron Bull is very difficult because it has to take into account the size, weight, and sturdy. I don't care about this. ”

"This is a fifty-horsepower iron donkey placed on the ground."

Because most of the animal power in the workshop is donkeys, Li Dejian called this thing an iron donkey.

"A type of iron donkey, can drive more than 100 16-axis yarn machines, is improving the transmission part, is expected to be this time next year, can bring 200 yarn machines to work together."

"Okay, what an iron donkey." Yao Silian of the Ministry of Industry shouted hello.

You must know that at present, Datang has reached a small bottleneck, that is, the amount of spinning cannot meet the weaving industry, and the demand for cloth is forty times that of Wude's seven years.

This is not counting the fabrics that need to be sold to Wajima, Funan and other places.

When the steam engine was first invented in history, it was used by the textile industry. Bulky, silly, but much less technical than the steam engine used in trains.

Compared with the tracked light steam tractor of willow, the technical content is not known how many times.

The tracked steam tractor of willow wood is the iron ox. At the moment, there is no one that can be cultivated for a day in a row, basically there will be problems in most of the day, all kinds of small problems, Ghost Gonggu is excited on the one hand, and sad on the other, and even young people like Li Dejian have white hair.

Li Dejian drew a third picture.

"It's a marine firefish, and it's a stupid ordinary cargo. The real refined high-quality fire fish should not occupy much space on the ship after being installed on the ship, and the operation is stable. ”
