Regarding His Royal Highness King Xin's question about the speed of the march, Zhang Yunyi thought carefully for a moment before he cautiously spoke: "Your Highness, our Ming army generally marches about 20-30 miles a day, and the elite soldiers can walk 50-60 miles. The horse team can travel about 80-90 miles a day.

There are more horses in the Houjin Tartars, and most of their elite foot soldiers also have horses. The distance they walk in a day is about the same as our horse team, which is also about 8 or 90 miles. ”

Zhang Yunyi seemed to remember something, his face darkened, and his voice paused for a moment before he solemnly emphasized: "Your Highness, the speed that the humble position said is the speed at which you can go to the place and take a short rest to enter the battle. If you don't consider the battle, the speed can be increased by about 5% by simply marching, right? ”

Hearing Zhang Yunyi's analysis of the old team, the pride in Zhu Youzhen's heart was extinguished at once. The youth team's daily travel of 100 miles is only the level of the elite soldiers of the Ming Dynasty, and this marching speed is completely at a disadvantage compared to the Houjin Tartar with horses.

Although the speed of the march does not directly represent the combat effectiveness, the speed of the march can quickly gather superior forces to launch a surprise attack on the opponent's weak points. Isn't Salhu the representative work of the Houjin Tartar? If you want to deal with the Houjin Tartars, you still have to think about limiting their mobility. Zhu Youzhen was a little distracted.

Forget it, Houjin is still far away, so let's look at the present, right?

"Yunyi, you prepare, Gu prepares the supplies, and you lead the team to send them to Xifengkou." Zhu Youzhen groaned for a moment and continued: "Tell Niu Jinxing to take a team of 200 people to escort the supplies together. ”

"Yunyi, you said those scattered soldiers of the grassland, can we hire them?" A thought suddenly popped into Zhu Youzhen's mind.

The archery skills of the steppe nomads are good, and if they can hire archers from the steppe, it will easily solve the shortcomings of the junior team's lack of long-range strike power.

Listening to His Royal Highness Wang's question, Zhang Yunyi didn't speak for a long time, and he was taken aback by King Xin's thoughts.

Can the Mongols also be hired?

But if you think about it, hiring Mongolian archers is a good move. But the problem is .......

"If you are not of my race, your heart will be different!" Zhang Yunyi dragged a rare sentence.

Hey, even a martial artist like Zhang Yunyi knows this sentence, and the Ming people's wariness of foreign races is still very strong? Zhu Youzhen was a little speechless. Maybe this is also one of the reasons why the Ming Dynasty has never been able to conquer the grasslands, right?

"Yunyi, you go down." Zhu Youzhen was a little interested, if he wanted to hire grassland archers, it seemed that he had to think about it.

However, no matter what strategy is adopted, one's own strength comes first. If you are not strong enough, you will rashly hire foreign aid, which is definitely the way to die. Zhu Youzhen has not forgotten this truth.

On the second day, Zhu Youzhen threw the preparation of materials to Wang Chengen to prepare, and he couldn't wait to inspect the Ming Dynasty's bird gun workshop.

The bird guns in the capital of the Ming Dynasty are all manufactured in the Wang Gong Factory Firearms Factory.

As soon as he entered Wang Gong's factory, Zhu Youzhen frowned.

The noisy Wang Gongchang Weapons Workshop made a very bad first impression on Zhu Youzhen.

How can there be so many people here?

When is this a bazaar?

It's a little too chaotic, isn't it?

This is also a place where firearms are made?

Zhu Youzhen was quite confused.

If this is an ordinary weapon workshop, it would be fine, but what kind of workshop is this?

Thinking that this workshop was a thermal weapon workshop that mainly made muskets and gunpowder, Zhu Youzhen couldn't help but feel a little frightened.

Gunpowder is no small matter.

The workshop of Wang Gongchang is mainly used for firearms and gunpowder, and there must be a large amount of gunpowder stored here. In such a chaotic order, once the gunpowder is ignited if it is not properly managed, it is not like a large explosives bag, which is destroyed in an instant.

Thinking of this, Zhu Youzhen couldn't help but tremble.

It's horrible.

The chamberlain who led the way was still boasting to Zhu Youzhen smugly: "Your Royal Highness King Xin, our workshop is the largest firearms workshop in the whole capital. Even all kinds of firearms and ammunition needed by the Shenji Battalion must be taken from us. ”

The more he praised himself, the more Zhu Youzhen felt terrible.

Listen, the largest workshop in the capital; The Shenji Battalion also needs to withdraw gunpowder from here, so how much gunpowder must be stored here?

Even if you estimate it conservatively, there are always tens of thousands of catties of gunpowder, right?

Tens of thousands of catties of gunpowder, even if the explosive power of black powder is weaker. But once something goes wrong, it will inevitably end up being shattered!

couldn't help but shudder again, Zhu Youzhen couldn't wait to stomp on the face of this waiter.

With such chaotic and dangerous management, you dare to boast to me?

However, it's not worth it to be angry with such a little person. It's all here, hurry up and read it, and leave as soon as possible. Zhu Youzhen silently comforted himself.

Wang Gong's musket making workshop is composed of more than a dozen separate courtyards.

Seeing the red fireworks in the courtyard, Zhu Youzhen was trembling.

Is there any mistake that there is an open flame here? There was an open flame near the powder magazine? I really don't know how to write death!

Forcibly suppressing the uneasiness in his heart, and hastily visiting the manufacturing process of the bird, Zhu Youzhen regained his self-confidence.

The production of muskets in the Ming Dynasty is not an assembly line operation, they are just the most basic division of labor and cooperation.

The barrel of the musket was made by 2 or 30 blacksmiths, and the process was very complicated. Zhu Youxiao said that he built a gun in 2 days, and I am afraid that time will be wasted here.

The workshop requires at least 3 blacksmiths to build a barrel.

First, the blacksmith would heat the wrought iron in the furnace fire, forge it into sheets, and then rotate it around a steel pillar.

In order to prevent the steel column from overheating and sticking, the assistant also has to frequently pump the steel column into the water to cool down.

After several times of heating and forging, the barrel is roughly formed, and then it takes 3 people to forge with all their strength to make the barrel fit tightly with the steel column; At the same time as forging, copper solder powder is added to weld the seams. A barrel is made.

Of course, this is only a half-finished product of the barrel.

According to different uses, the barrel also needs to be reprocessed, such as the long-barreled bird gun, and the barrel must be lengthened.

The semi-finished barrel for good use also uses a drill bit to smooth the inside of the barrel, and then it enters the most troublesome stage: barrel engraving.

The rear end of the barrel needs to be carved out of the thread, and then the end of the barrel is screwed with an iron plug similar to a screw, and then the iron plug is welded to the barrel. In this way, the tail end of the barrel can withstand the deflagration of gunpowder and will not leak.

After such tedious steps, the barrel of a musket was completed.

Zhu Youzhen noticed that the barrel of the bird gun was not the same thickness as the front and back. It is slightly larger at the end of the gun, slightly smaller at the muzzle, and distributed in a gall-shaped shape, and its appearance is not round but 8 stunned.

Wang Gongchang is worthy of the name of his arsenal. The blacksmiths in the factory are highly skilled, and the rhythm of the forging is like a flowing cloud, revealing a unique beauty.

At their rate, a group can produce about two barrels a day (barrels without bore bore). This speed is indeed the highest blacksmith level in the Ming Dynasty.

Curiosity about the craft made Zhu Youzhen forget the threat of the powder magazine for a while, and he followed the process to carefully visit the past.
