Da Ming started to ascend the throne

Zhu Youjian walked to a drilling machine. This is a very primitive drilling machine, but it is much more efficient than manual drilling.

Several craftsmen were making gun barrels. They worked very carefully and seriously, and they didn't even notice when two people walked up to him.

"Spiral rifling?"

Zhu Youjian was surprised to find that one of the craftsmen among them was actually doing spiral rifling.

Although the Royal Guard is equipped with rifled guns, the barrels are straight.

Zhu Youjian didn't expect Zhao Shizhen to have figured out the rifled gun.

If the development is successful, this is no small matter, a great invention.

However, it is best to use Minie bullets for this kind of gun. Only with Minie bullets can its power be maximized.

Although Zhu Youjian gave all these production drawings and craftsmanship to Zhao Shizhen.

However, it should be difficult to develop it with the current technology, and Zhu Youjian has no hope.

He patted the craftsman and asked:

"Has this gun ever been made?"

The craftsman was suddenly photographed. He was startled and looked back.

I saw a very imposing middle-aged man and a beautiful girl standing beside him.

Knowing that ordinary people cannot enter the workshop, he should be inspected by the Ministry of Industry, so he hurriedly replied:

"Yes, there may be more than a dozen of them, all of which were taken by Mr. Zhao."

"Oh, very good, how much is your monthly salary, and is it paid on time?"

"Reporting to my lord, the small salary is six taels of silver a month, and it will be paid in full and on time!"

Zhu Youjian nodded in satisfaction, and then walked to the office not far away.

When the two came to the office, they opened the door and walked in.

Zhao Shizhen was playing with a rifled gun, and when he heard someone coming in, he pointed the gun directly at the person coming:

"There are no rules, next time you enter my office, you have to knock on the door, otherwise..."

Chapter 323

Zhao Shizhen just wanted to say:

"boom"

Suddenly seeing that the person who came was Zhu Youjian, the emperor of the Ming Dynasty, he trembled all over at that time, and hurriedly got up to salute:

"I see your majesty, I don't know your majesty coming, please forgive me!"

Just kidding, in front of the emperor, you can't bring any weapons, but he actually pointed a gun at the emperor. Even though he didn't know it was the emperor, if the emperor pursued him, it would still be an unforgivable crime.

Of course, for his beloved general, Zhu Youjian knew that he was unintentional, so he didn't care at all.

Zhu Youjian looked at the panicked Zhao Shizhen and smiled:

"Is there any bullet in the gun?"

"No...no, it's completely empty, and the bullets haven't come in yet."

Zhu Youjian laughed loudly, and reached out to support Zhao Shizhen:

"I know you didn't do it on purpose, hurry up and flatten yourself!"

"Thank you, Your Majesty, oh yes, I am about to report to you that the ironclad battleship has been launched for sea trials, and this bullet has also been developed by me."

As Zhao Shizhen said, he showed Zhu Youjian a bullet in his hand. Zhu Youjian's eyes lit up, and he reached out to take the cone-shaped bullet and looked up and down.

"Fuck, isn't this the Minnie bomb? It was actually developed by you. If you can actually fight, I will reward two beauties from different races, plus a thousand taels of silver."

The diameter of the tapered bullet is slightly smaller than the diameter of the barrel, which is very convenient for loading.

There is a conical cavity at the bottom of the bullet, and a cork blocks the bottom of the hole. When firing, the gas presses the cork into the cavity, forcing the bottom of the bullet to expand, close to the rifling, and close the gap between the bullet and the chamber, allowing the gas to It cannot be leaked out, and the warhead can be rotated at high speed under the pressure of the rifling.

Minie bullets solved the problem of difficulty in loading rifled guns and the low range accuracy of smoothbore guns, making the rifle a decisive weapon on the battlefield.

But the Minie bullet has some unsolvable problems. It can only be made of a very soft alloy such as lead, so that the bullet is easy to expand.

The warhead is soft and deforms immediately after hitting the target. The stopping effect is good, but the penetrating power is too weak.First release.. @@@..

Similarly, in order to quickly expand the warhead to lock the chamber, the propellant can only use fast-burning gunpowder, and the development trend of propellant is slow burning, so that the warhead can be accelerated uniformly in the chamber for a long time to increase the initial velocity.

A rifled gun has rifling inside the barrel; when a bullet is fired, the bullet is forced to rotate and fly by the thread engraved in the barrel.

Therefore, it has the precise pointing and long-term stability in high-speed movement that smoothbore bullets do not have, making long-distance sniping possible.

However, the rifle gun has the disadvantages of difficulty in loading ammunition and low firing efficiency, which is compensated to a certain extent by the invention of the "Mini bullet".

The caliber of the Minie bullet is a circle smaller than the diameter of the barrel of the front-loading rifle gun, which solves the problem of difficulty in filling the bullet; a small hole is dug at the bottom of the bullet.

When fired, the bullet is ignited to expand and cling to the barrel of the gun. Under the pressure of the rifling, the bullet can rotate out at high speed, and the hit accuracy is greatly improved.

The Mini Bullet is a revolutionary invention in the history of bullets, with a range of 500 meters and an effective range of 300 meters, with improved accuracy.

How did Zhao Shizhen know that this thing has been ahead of the world for nearly a hundred years. When he heard the emperor's reward, he scratched his head in embarrassment:

"Your Majesty, I don't want beauties, but I need silver. This arsenal and shipyard are gold-swallowing behemoths!"

"Snapped……"

Zhu Youjian happily slapped Zhao Shizhen on the shoulder, and Zhao Shizhen was shocked when he slapped him.

"Gold-swallowing giant beast? Then tell me, how much silver do you need?"

Zhao Shizhen said without the slightest hesitation:

"If you want to equip this kind of rifled gun with the Ming army, you need at least 300 million taels of silver a year, not counting battleships."

"Well, there is no problem. The 1000 million taels of warships have already been given to the commander of the navy, and Zheng Chenggong will give it to your Ministry of Industry."

"Of order, thank you, Your Majesty."

Zhao Shizhen was immediately overjoyed. If there is enough financial support, the battleship guns are not a big problem, but it will take a little longer.

"Zhao Aiqing, how many of these guns are out now?"
