He Renlong garrisoned Guihua City and did not launch an offensive eastward.
Therefore, on the east side, there were naturally Datong, Xuanfu, Jizhen and other imperial border troops attacking.
What is a little different from the Hetao area is that in eastern Mongolia, Du Yinxi, the governor of Jiliao, sent Mongolian court soldiers back to lurk in advance. Therefore, he could get more accurate information and get responses, only for the upper echelons of each tribe.
action.
……………………
While there was a big movement on the grassland, the sons and grandsons of the Ryukyu envoy Zheng Zhou had arrived in the capital and presented their credentials. In response, Emperor Chongzhen personally received them and told them clearly that the imperial court was already setting up a Ryukyu expeditionary force to let them
They returned to Matsue Prefecture and reported to the Ryukyu Expeditionary Force.
Emperor Chongzhen also cordially received the Tagawa family and Zheng Zongming who were accompanying them and took photos as a souvenir. He also granted the title of First Grade Lady to the Tianchuan family. Zheng Zongming was sent to Denglai Navy to serve under his father.
The 19th year of Chongzhen was the first year of the Ming Dynasty's strategic offensive. Both the north and the south would launch offensives. However, within the pass, it had little impact and it was still peaceful and prosperous.
The Ryukyu envoy, Zheng Zongming and others, witnessed the prosperity of the capital before leaving the capital.
On this day, outside the capital city, there were huge crowds of people, all crowded on the edge of the endless farmland in the suburbs. Of course, ordinary people could only stand outside the line guarded by the soldiers of the Five Cities Soldiers and Horses Division.
Everyone was talking about it, and everyone was very excited.
"It is true that the imperial court attaches great importance to spring plowing, but why is there such a big scene in this year's spring plowing?"
"Don't you know? The emperor is coming to do the eye-dotting in person! Of course it will be grand!"
"The highlight? What's going on?"
"It's a good thing that you are still from the capital. There have been rumors two days ago that the branch of the Royal Academy of Sciences of the Ming Dynasty has been ordered to build an iron ox. Why don't you come here to see how rare it is!"
"Iron Ox? There are already steam trains. Isn't this Iron Ox rare?"
"That's what I say, but have you ever seen Tieniu? They're just here to watch the fun!"
"..."
The people here in the capital were already accustomed to seeing steam trains, so it was natural that they could no longer imagine the Iron Ox. However, they were somewhat surprised that steam engines could also be used in farming.
Those who are close and in a good position can see a huge object covered with red cloth in the farmland. That should be the Iron Ox, waiting for the emperor to put his eye on it.
Generally speaking, throughout the dynasties, no matter what emperor they were, they attached great importance to spring plowing. Even before the start of spring plowing, some emperors would worship the fields, then personally help the plow and plow the land symbolically to show that the court valued it.
Emperor Chongzhen was no exception. When Liu Weichao introduced it to him, he said that although there were few people in Liaodong, after the imperial court was restored, it could become a grain factory with mechanized production, which aroused his great interest.
After watching the video sent to him by Liu Weichao, Emperor Chongzhen immediately asked Liu Weichao to give him these mechanical design drawings, and he wanted to build them as soon as possible.
In fact, mechanized production is not difficult, the main thing is the power system. Other molds used for farming are unimaginable at best, but with the drawings of later generations, it is not difficult to create them.
Generally speaking, at least it must be an internal combustion engine.
Although the historical process from steam engine to internal combustion engine originally took a long time, with the help of Liu Weichao, various internal combustion engine drawings of various historical stages can be provided to the Ming Dynasty's skilled craftsmen who have experience in building steam engines. In fact,
It's not difficult. At most, it's impossible to mass-produce, the cost is too high, and it can't be promoted on a large scale.
However, the Ming Dynasty actually had zero foundation in the chemical industry. The experience gained from alchemy was basically useless, and it was only done by Taoist priests, and it was not popular.
Although chemistry has begun to be promoted, the highest level only has a basic university foundation, and only a small number of people are studying it. For petrochemicals and three acids and two bases, the court is actually still in the preparation stage, and the couple Xia Wanchun and Zhu Yuluo are the leaders.
.
This time Tieniu used a miniaturized steam engine. If you want to use an internal combustion engine, it will take at least one or two years. Because the first batch of physicists such as Xia Wanchun and Zhu Yuluo are too busy.
On the one hand, they must continue to teach themselves the most advanced knowledge of the Ming Dynasty. On the other hand, they must, as teachers, pass on their digested knowledge of the science of medicine to the second generation of talents.
Only by recruiting several more talents to study the science of science and technology in Ming Dynasty can Ming Dynasty have a stronger foundation in the science of science and technology, so that people can start to apply the science of science and technology on a large scale.
As for Emperor Chongzhen, he was still very young, only in his thirties. He had plenty of time, and he did not want to fish in the marsh and only catch a few talents who were good at studying things. What he wanted was not to say that everyone was a qualified person.
, at least when he wants to use it, there will not be so much shortage, so that the Ming Dynasty will have a hundred flowers blooming, and all walks of life can flourish with the addition of talents who study physics.
That is to say, according to Liu Weichao, productivity will be greatly improved.
No, under the gaze of everyone, Emperor Chongzhen led hundreds of civil and military officials to the ground. After worshiping the divine farmer of heaven and earth, he finally had the red cloth removed, revealing the figure of Iron Bull.
This revelation made many people a little disappointed. Although it was called Iron Niu, it really didn't look like Iron Niu. It looked weird and awkward.
Under the attention of everyone, Emperor Chongzhen stepped forward and clicked twice with a red pen on one of them, which looked like a head, probably a steam engine, completing the eye-dotting ceremony.
Afterwards, everyone watched the next action.
The steam engine started to ignite, and thick smoke came out of the chimney. After a while, the operator turned on the light, and the power of the steam engine piston was transmitted to Tieniu's feet.
Among them, the iron bull's front feet are holding a layer of iron and can rotate, dragging the iron bull forward, but it will not let the iron bull sink into the ground and become unable to move.
In addition, Tieniu's hind legs are somewhat similar to a horizontal mace, with curved sharp knives all over them. As Tieniu moves forward, the row of sharp knives rolls up, inserts into the soil and then brings it out again, completing the turning of the soil.
The iron bull rolled forward, and the iron bull's hind legs completed the renovation of the soil in the grain field, so that wherever the long mace passed, it was filled with renovated soil.
If this were changed in the past, farmers would have to use hoes to renovate the fields one by one. Those with more money would have to use oxen to plow the fields.
Just such an iron cow can actually complete the work of at least four or five cows at the same time.
Looking at this scene, everyone was a little dumbfounded: This efficiency is too high, right?
The person responsible for building this iron bull was Fang Yizhi from the Ming Dynasty Royal Academy of Sciences, a top student with perfect scores in physics. At this time, he was beside Emperor Chongzhen and introduced with a little regret: "The steam engine is still too heavy, so this
Planting iron bulls requires hardness of the land to be renovated. If it is too soft, the iron bulls will sink in and be unable to move."
The steam engine currently used by Tieniu has been miniaturized and reduced in weight as much as possible, but the restrictions are still relatively high.
After hearing this, Emperor Chongzhen looked at the iron cow that was smoking away, but he smiled and said: "It's already good. You first think about how to mass-produce the iron cow, or try to mass-produce the iron cow. When the chemical industry matures, there will be more
After using easy-to-use fuel and using internal combustion engines, these will no longer be problems!”
Having said this, he turned to look at Fang Yizhi and encouraged: "Work hard, even if it's just step by step, our Ming Dynasty's technology will make rapid progress!"
The iron ox powered by the steam engine in front of us is also what the Ming Dynasty currently needs. The North China Plain, the Central Plains, and the newly conquered Hetao Plain all need this kind of iron ox to supplement the lack of manpower.
Or according to what Liu Weichao said, mechanization should be used to liberate more farmers and free them from the shackles of farmland. In addition, reading and literacy are being promoted nationwide. When the Ming Dynasty transforms from an agricultural country to an industrialized country, it will
Have a good talent base.
And in today's world, the Ming Dynasty is the most powerful country, and the government controls the entire world, so the entire world will be a tilted place for goods produced by the Ming Dynasty's industrialization.
This is Daming’s future plan!
Thinking of this, Emperor Chongzhen focused his attention on the iron ox in the distance. A farmer nearby was adding coking coal and water to the iron ox, and then continued to drive the iron ox to plow the ground.
Under normal circumstances, there will be a group of people waiting on the side. If the iron ox plows the field and reaches an area that is too soft, it will need to be pulled out by manpower or animal power, and then continue plowing after bypassing the field that is too soft.
In other words, there are specialized prospectors who evaluate the grain fields in advance to see if they can bear the weight of iron oxen, so as to decide whether to plow the land with iron oxen or with animal power.
Ultimately speaking, Tieniu still has its inconveniences.
However, Emperor Chongzhen, who knew the future direction, was not dissatisfied at all when looking at Tieniu in the distance. Just as Fang Yizhi said, this was just the first step. Ming Dynasty was already on the right path.
All that needs to be done is to solve the problems that arise and then move forward.
………………
Just when the capital of the Ming Dynasty was about to start busy with spring plowing, the port of Busan in the far south of North Korea was also crowded and very lively.
The Japanese side was no exception. Before spring plowing, as many Japanese farmers as possible were moved to North Korea.
No, these days, there is an endless stream of ships traveling between North Korea and Japan.
The farmers who arrived first are still here waiting for distribution; the farmers who arrived later are crowded at the port. The population is probably the largest in the history of Busan.
However, they did not know that in the mountains in the distance, someone was watching the situation at the Busan port with the help of telescopes.
