The moon gradually set behind Mount Else, and Murphy returned to the castle through the side door.

Removing the gun from his back, Murphy didn't even change his clothes, and ran towards the study in his workman's clothes, without even eating.

"Let me see which genius engineer is the work of a genius engineer who can make such a weapon with just a small quota from the arsenal?" Murphy thought to himself, then took out a screwdriver and slowly disassembled the entire gun.

In fact, when the bolt was first removed, Murphy had already seen through the design principle of the gun.

The use of a firearm to fire a bullet is a part of the high-pressure gas behind the bullet to provide the force to push the bolt back, thereby pushing the bolt, which is one of the most classic semi-automatic principles of air-conductive rifles.

Just like the AR-15, there is a small hole in the barrel for gas conduction. After the bullet flies through the air hole, some of the high-pressure gas that appears after the gunpowder is burned will enter the air hole, while most of the other high-pressure gas will continue to propel the bullet forward.

When the pressure is higher than the pressure of the re-entry spring, the gas pushes the air duct seat on the bolt frame into the bolt frame, so as to advance the bolt forward, push the bolt frame backwards, and then use the inertia of the entire gun unit to load the gun like pulling the bolt with a hand.

There is another semi-automatic method, which uses the recoil of the firearm to act directly on the bolt frame, thereby pushing the gun crew backwards.

For example, the famous Barrett, MP5, etc. are all used in this semi-automatic way.

"Interesting, it's also a talent to think of the air-conductive semi-automatic method, and I thought that the first semi-automatic method to appear would be the recoil or even the otherworldly magic method!" Murphy couldn't help but laugh after checking the barrel.

"Very well, more talents like this, more people can contribute to our development and construction!" Murphy said with satisfaction.

He decided not to bully people personally, but to let these innovative people innovate on their own, get rich by their own innovation and hard work, and then get rich first to lead the latter to get rich, and take the most historically proven and correct path.

"However, although semi-automatic rifles and automatic rifles can now be made, they still cannot be installed on a large scale, otherwise it will cause great waste, because a large number of bolt-action rifles produced by the Weapons Reform Act have been retired before they are in service, and the more than 20,000 gold nuts are equivalent to a waste of money. Murphy muttered to himself.

And there is another reason, that is, the production capacity is still insufficient, at least dozens of bullet production lines must be added to meet the bullet consumption of semi-automatic rifles and automatic rifles.

"Although it is not possible to produce large quantities of automatic rifles, it is still possible to produce small quantities of some to arm the Leviathan and the Castle Guard. Murphy nodded, muttering to himself.

With that, Murphy picked up his pen again, which had changed the military, economics, and politics of Remloth Castle, and wrote and drew between the papyrus, and it took a long time to draw a standard plan.

"It's done! The famous AKM! Simple can't be simpler, as long as the steel is qualified, you can build as much as you want!" Murphy spread out the design drawings in front of him, breathing a sigh of relief.

"But in this world, you can't call it anymore, and people here don't know what it means. Murphy looked at the "unintelligible" Russian letters on the left side of the drawing, and was a little confused.

"Why don't you just call it the Sorens III Type 26 rifle?" Murphy shook his head, "No, it's not imposing, and it's easy to be put on the line in this era." ”

"Or can you call it the 'Holy Light God' rifle, which means to bring people to the Holy Light Heaven?" Murphy raised his eyebrows, "This is okay!

Murphy picked up the pen, crossed out a few Russian letters of the AKM, and wrote the "Holy Light God" rifle in Wallyne script, which was a little more merciful than the unforgiving nature of the "Vulcan" revolver, and the uprightness of the "Justice" cannon that adhered to justice.

"Alright! You can go to sleep! Tomorrow I will hand over the manuscript to the Arsenal, and then produce a small number of 300 pieces, and the caliber will be according to the NATO standard of 7.62*51mm, and strive to put them on the 'Leviathan' before Crescent City is rebuilt. Murphy stretched.

"Although they are both air-conductive rifles, the AR series rifles have a direct gas conduction method, while the AK series has a long-stroke piston gas conduction type, which I can just consider adding some diversity to the development of weapons. Murphy said, then casually opened the drawer under the desk, intending to put the manuscript in the drawer.

"Wait!What's going on??,' Someone touched my drawer?"

"I left the study office at about seven or eight o'clock in the evening, and when I left, I forgot to close the window, and asked an attendant to help close the study. Although Murphy was a little angry, he didn't show it, but thought calmly.

"It's two o'clock in the morning, but we have to check it out right away, otherwise something might happen. Murphy said lightly.

"Philip!" Murphy walked out of the study and called out to Philip the butler.

"Your Highness, I'm here!, what's wrong?" shouted for a minute, and a well-dressed Philip came out of his room to report to Murphy's side.

"It's not a small matter, I suspect that there are spies among our squires, as for who it is, I have an answer in my heart, but I'm not sure yet. Murphy said with a gloomy face.

"Why don't I gather all my attendants and let your Highness interrogate them?" said Philip.

"Yes, be quick, don't miss anyone, and I'll compensate them for their breaks afterwards. Murphy nodded and said.

Seeing Murphy's nod in agreement, Philip went to the squire's quarters and knocked on the door from room to room.

After about ten minutes, almost all of the attendants were standing in front of Murphy, but not including the one who had helped him close the window.

"Where's Blake, why didn't he come?" asked Murphy aloud, there were only ten squires in the castle, so every Murphy could remember and say the name of the squire.

"Blake said at twelve o'clock in the evening that he was going out to buy supplies, because the supermarket is mostly closed at this time, and we usually go to the supermarket to buy supplies wholesale at this time, so it stands to reason that he should have come back at this time. Blake's roommate shook his head and said.

"Do you want to abscond, declare it, list Blake as a fugitive, give the portrait to all the sheriffs, and the whole city wants him!" Murphy sneered, then ordered.
