Iron Dynasty

When the fish's belly turned white in the east, the Suwon Bridge Camp blew the bugle to get up.

In the ten-mile-long camp, the soldiers of the Great Yu Kingdom and Goryeo all got up and started cooking.

In such a quiet and beautiful scene, Ye Qingyun and Qu Dong came out of the camp almost at the same time.

In the camp, a bugle is a military order, and both generals and soldiers must obey it. This is the iron-like discipline of the army of the Great Yu Kingdom, and no one can specialize it.

In Suwon Castle, Edo Yiming didn't sleep all night, and his red and swollen eyes looked at the dense smoke from the kitchen in the distance. It won't be long before the mixed army of Dayu Kingdom and Goryeo will arrive at Suwon Castle.

Here, they will have a formal confrontation with the army of the Great Yu Kingdom.

Junichi Koizumi was also on the city wall, and behind him were the Goryeo people tied up with ropes. After the war started, these people would be pushed down in front to resist the bullets of the soldiers of the Great Yu Kingdom.

At the same time, the Japanese soldiers in the city were wiping their muskets. Most of the soldiers were holding arquebuses, and a few were holding flintlock guns.

Compared with the simple structure of the matchlock gun, the flintlock gun is more complicated in the manufacturing process, and only 8,000 flintlock guns have been produced so far.

Five thousand of these flintlocks were given to Edo Izumi's army to show how much Yamada held him.

Because of this, Edo Yiming dared not imagine the consequences of defeat, because the defeat of the war would bring great pressure to Yamada Daimyo.

The other daimyo took advantage of this opportunity to oppose him.

The sun gradually rose, and the atmosphere of war became more and more intense. Japanese soldiers lit the torches and stood in front of the artillery, ready to fight at any time.

The elite five thousand flintlock soldiers were arranged by Edo Yiming on the east city wall. There was an empty rice field directly opposite here. He believed that the Dayu Congress would launch an attack here.

Time passed, and soon the Japanese soldiers on the wall saw the Goryeo army coming towards them.

These soldiers did not rush to attack the city, but walked around the city in an orderly manner, besieging Suwon Castle.

This scene surprised Edo Yiming on the castle wall.

Ye Qingyun and Qu Dong led the army of the Great Yu Kingdom and settled in front of the official road in the south of Suwon City.

Qu Dong picked up the binoculars and looked at the heavily guarded Japanese soldiers on the city wall.

In the military course of the Son of Heaven Academy, he once asked the emperor about the situation of the Japanese army, and Xiao Ming told him about it at that time.

He believes that Japan is a very short-sighted country. It never considers the consequences of doing things. Its foreign strategy is not thoughtful, but like a gambler.

Once they've decided on a plan, they'll all bet on it until they've been beaten to death, and when they're strong again, they'll have enough gambling capital to do it again.

The reason why the Japanese state has such characteristics is due to the fact that one side of the country has water and soil to support the other side. The Japanese country has a small territory and lacks resources.

Ye Qingyun was noncommittal, he said: It's really a fool, their supplies have been cut off, why should we attack the city, just starve them to death is enough, not to mention that we can surround and help here.

Qu Dong nodded, this was their plan, they would spread the news of the siege of Suwon City, and wait for the army of Japanese pirates to come to help.

At that time, the Japanese army who came here can be easily defeated.

...

Qingzhou.

Lin Wentao smiled as he looked at the industrial master machine with silk-meter-level precision in front of him. The so-called industrial master machine is a machine that manufactures machines and machinery.

It can be said that the mother machine is the cornerstone and cradle of the entire industrial system, and determines the foundation of a country's industrial level.

In the past seven years, the accuracy of the Great Yuguo industrial machine has remained at the millimeter level, which is enough for the first generation of steam engines, flintlock guns, artillery, production machinery and other rough machinery.

But in the face of breech guns, second- and even third-generation steam engines, and various precision machinery in the workshop, it is far from enough.

It is for this reason that the emperor will upgrade the schedule of the industrial mother machine with silk-meter-level precision.

Now, with the accumulation of technology and the assiduous experiment overnight, they have finally produced the first batch of measuring tools at the silk meter level, some of which are installed on it as part of the lathe.

Craftsmen who produce spare parts can make more precise parts directly through measuring tools.

Through the emperor's explanation that day, Lin Wentao basically understood the principle of precision machine tools. At that time, the emperor even played a very interesting example. He said: There is a dog in the palace, and this dog can chew noodles and pancakes like a dog. It's round, but if I take the cake and slowly grind it on his teeth, I can grind it out to a perfect circle.

In this example, the dog is the machine tool, representing the machining accuracy of the machine tool itself. The emperor likened himself to a machine tool craftsman, representing the measurement accuracy.

Simply speaking, improving the accuracy of the machine tool includes two aspects. The first is the precision machining of the machine tool itself, and the second part is that the craftsman uses a precision measuring tool to measure and correct the deviation. Both of them are indispensable.

A millimeter-level lathe can only produce parts with a millimeter-level error, and a silk-meter-level lathe can only produce parts with a silk-meter level error, and then manual grinding is required.

This incident made him understand that the manufacture of more accurate industrial machine tools can only rely on manual grinding. Because of this, the current lathes have more precise accessories. Through manual correction, the accuracy of the lathes has been further improved. improve.

Coupled with the emergence of silk-meter-level measuring tools, he believes that these batches of machine tools have reached the standard required by the emperor. With these batches of lathes, the industrial level of Dayu will also enter a new era.

When he was happy, suddenly a hearty laughter came, this familiar voice made him turn around immediately.

Your Majesty! Lin Wentao bowed and said.

Xiao Ming waved his hand to let Lin Wentao excuse himself. During this time, he had been paying attention to the lathes, so he rushed over after Lin Wentao had made all kinds of lathes.

Looking at the screw lathes, gear lathes, drilling machines, boring machines, etc., Xiao Ming smiled with satisfaction.

In the past, although he attached great importance to lathes, he never formalized the production of lathes. After all, the industry at that time was still in the stage of barbaric growth.

Now that the precision concept of the industrial mother machine is proposed, the lathe itself should also be paid attention to. He said to Lin Wentao: It's done well, but you can't be idle now, you must immediately build a lathe workshop and select a group of old craftsmen. , specializing in the manufacture of high-precision lathes.”

Lin Wentao looked excited. The appearance of high-precision lathes meant that he could manufacture more machines, which was a fatal temptation for him who was a machine fanatic.
