Traveling through history leaving a name

Chapter 24 Gifts (additions for book friends who voted for recommendation)
For the next few days, Xun Yu didn't go anywhere, just watched how Zhang Qingfeng made gifts for him.

He saw Zhang Qingfeng cut out pieces of copper and iron with a machine, and then processed them into individual parts with a milling machine.

While Zhang Qingfeng was working, Xun Yu was talking to him.

As a modern person after 2000, Zhang Qingfeng is very arrogant in his bones.

Although he may not be as good as the geniuses of this era in terms of strategy, no one can match him in terms of breadth and depth of vision and knowledge.

On this day, Xun Yu asked Zhang Qingfeng, "Brother Ruixiang, if you are allowed to serve as an official in the court, what can you do?"

Regarding Xun Yu's question, Zhang Qingfeng said very arrogantly: "If I am allowed to take charge of agriculture, I can double the food for the people under the imperial court. If I am allowed to take charge of business, I can make the imperial court's wealth multiply exponentially." Increase, even if I let me manage one side, I can still manage the local area into a fertile land."

"What if you are allowed to join the army?" Xun Yu asked.

"If I were to join the army, I would choose a few people who can serve as soldiers and fight, and I would be responsible for making their combat effectiveness stronger."

"How to make the army more powerful?" Xun Yu asked again.

"Just imagine, if an army is equipped with indestructible weapons and armor that can't be hurt by swords, can they still lose?" Zhang Qingfeng asked.

"You're talking about heavy armored soldiers, right? But heavy armored infantry is too expensive. If there are too many, the court can't afford to support them. If there are too few, they won't be of much use in the battle." Xun Yu said.

"You are wrong. Since I said it, I can do it." Zhang Qingfeng said: "Whether it is heavy armored infantry or cavalry, the most important thing is weapons and armor. It may take a year or so for a few craftsmen to create a set of armor. Well, it seems that making armor is really difficult and expensive. But if I make it with machines, as long as there are enough machines and hands, I can make thousands of them in a day, and the cost is very cheap."

Finally, he asked Xun Yu: "If you can do this, do you still think it is difficult to raise heavy armor soldiers?"

Hearing Zhang Qingfeng's words, Xun Yu was slightly absent-minded. After he realized it, he said: "If you can really do what Brother Ruixiang said, then it is really not difficult to equip a powerful heavy armor."

He obviously didn't believe what Zhang Qingfeng said.Why make thousands of armors a day, how is this possible?

"Actually, heavy armor soldiers look powerful and advanced, but they will eventually be eliminated by history."

Zhang Qingfeng said: "I know that there is a weapon that can shoot farther than a bow and arrow, and can shoot through heavy armor from a hundred steps away. If this weapon is equipped in large numbers, no amount of heavy armor will be enough to kill it."

In ancient times, two steps counted as one step, about 1.3 meters to 1.5 meters, and more than 100 steps were at least 50 meters.

"Brother Ruixiang, what kind of weapon are you talking about? It's so powerful." Hearing Zhang Qingfeng's words, Xun Yu asked in surprise.

If weapons that can break through heavy armor at more than 100 steps are equipped in large numbers, who else can win?
"I can make this kind of weapon. If you can stay here for half a month, I can find a way to make it for you." Zhang Qingfeng said.

The weapon he was talking about was naturally the flintlock gun of later generations.

In the view of Zhang Qingfeng, a science graduate, the structure of the flintlock gun should not be too simple. What restricts him from making flintlock guns is nothing more than the processing of the barrel.

However, he now has a relatively precise machine tool, and if he grinds it slowly, he can always grind out a flintlock gun in ten days and half a month.

Of course, he can also use copper pipes to make flintlock guns, so that the processing difficulty will be geometrically reduced.

However, the copper tube can withstand the pressure too low. If copper is used as the barrel, the wall of the tube must be thickened. This will make the flintlock too bulky and not suitable for him to use as a force.

"Of course I have time. I still have a lot of puzzles and I want to ask brother Ruixiang for advice."

Hearing that Zhang Qingfeng made the weapon he said, Xun Yu immediately regained his spirits.

As long as he really has this kind of weapon, let alone half a month, even if he stays in Erdaogou Village for a year, Xun Yu will not hesitate at all.

------

A few days later, under Zhang Qingfeng's making, the gift he threatened to give Xun Yu was finally made.

This is a pendulum clock the size of a washbasin. There are three kinds of hands on the pendulum clock: hour hand, minute hand and second hand.

On the clock plate, there are twelve hours such as Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai, etc. Each time the hour hand moves is an hour (an hour in ancient times is equal to a modern hour). two hours).

Each hour is divided into five divisions, a total of 1 divisions, and each division of the minute hand is [-] minute.One step of the second hand is one second.

Zhang Qingfeng's design not only takes into account the time-keeping habits of the ancients, but also takes into account the time-keeping methods of later generations.

"It's just amazing."

After seeing the pendulum clock assembled and manufactured by Zhang Qingfeng, Xun Yu was shocked for a moment.

"Wen Ruoke is still satisfied with this gift?" Zhang Qingfeng asked with a smile.

"Satisfied, very satisfied." Xun Yu looked at the pendulum clock hanging on the wall of his room with joy on his face.

Zhang Qingfeng could also tell that Xun Yu really liked this pendulum clock.

After making the pendulum clock, Zhang Qingfeng will make the flintlock gun next.

What he wants to make is of course not the kind of short-barreled flintlock, but a powerful long-barreled flintlock.

The most difficult part of making a flintlock gun is the processing of the barrel.

The most primitive muskets are rolled up with iron sheets. The barrel of this kind of gun is not pressurized enough, and it is easy to explode.

What he wants to make is a gun barrel drilled out of solid steel pipe.

In order to manufacture this gun barrel, Zhang Qingfeng spent a lot of time, mainly improving the milling machine and temporarily changing the milling machine into a drilling machine.

Of course, the most important thing is the drill bit. In order to use limited materials to manufacture a drill bit that can process low-carbon steel pipes, Zhang Qingfeng used all the knowledge he had learned.

For this reason, he also sent people to collect raw materials outside, and it took more than a month to make it.

After the drill bit is made, it is much easier to process the steel pipe.

After a few days of work, Zhang Qingfeng got out a good barrel.

It is much easier to make a bolt than a barrel.

What Zhang Qingfeng made was a percussion flintlock gun. He hit the anvil with a hammer sandwiched with gravel, ignited the gunpowder in the powder pool, ignited the gunpowder in the powder pool, and then ignited the gunpowder in the gun barrel, and finally achieved The purpose of firing bullets.

The structure of the percussion flintlock gun is very simple. With the barrel, Zhang Qingfeng only spent a few days to assemble a flintlock gun.

As for the propellant for the flintlock, Zhang Qingfeng had already prepared a lot in this more than a month, and it was the best ratio of granular black powder.

The day after the flintlock gun was manufactured, Zhang Qingfeng invited Xun Yu to test the gun.

"Brother Ruixiang, are you sure this thing can shoot through heavy armor from a hundred steps away?"

Xun Yu looked at the strange weapon in Zhang Qingfeng's hands, still in disbelief.

"Try it and you'll know." Zhang Qingfeng said.
