Listening to Gao Xianda's words, Nan Huairen fell into thought. Pen & Fun & Pavilion www.biquge.info

He's just a scientist himself, and he doesn't really understand the things of war. The cannons he saw when he was in Europe fired this kind of iron lumps, so when he came here, he still thought of using iron balls as cannonballs.

I didn't know that this cannon was originally a naval gun, and the iron ball was used to deal with the hard planks of the ship. If the main focus is on anti-personnel forces, it is necessary to replace them with scattered shells such as grapeshot shells.

"However, if you use explosives as shells, they can blow up and it will be difficult to ......control ignition," Mr. Nan said.

"You can make an exact lump of iron, hollow out the inside, fill it with explosives, and leave a long lead on the outside. The two wires are ignited together, so that when the shell hits the opposite side, it will explode just right. Gao Xianda said.

Nan Huairen originally wanted to refute it, but he suddenly found that Gao Xianda actually made a lot of sense. Seems to work.

In addition, if you replace the solid shell with an explosive shell, the mass becomes lighter, and the same cannon can be projected at a longer distance, and at the same time, the power can be increased.

Gao Xianda saw that Nan Huairen was silent, and felt that he was right, so he added, "And I think your way of putting the gunpowder first and then putting the bomb after compacting is also very unscientific, why don't you pre-prepare and compress the gunpowder and put it in a container with the shells?" When the time comes, put this whole in and ignite it directly, can't it be launched? ”

"Don't you feel tired that your shells have to be installed from the front every time? Now the barrel is only one meter, which is fine. If the barrel is lengthened in the future, will it not be possible to reload from the front? ”

"Also, there is a problem with the design of your wheels and bearings, which can neither weaken the recoil when firing the gun, nor is it convenient to move. Why not design a gun mount that grabs the ground underneath and has shock absorbers on top? As long as the barrel is attached to the gun rack and fixed, the gun can be fired directly. ”

Gao Xianda asked several questions one after another. He didn't really know much about artillery design, but he had seen the models made by Berkeley and Akatsuki, as well as the cannons in modern armies. He knew what a modern cannon should look like. What he said was basically common-sense questions. But his common sense is more than 300 years ahead of this era!

Therefore, a few of his ideas stunned Nan Huairen at once!

Kangxi also felt that what Gao Xianda said was very reasonable, and he knew that with the current level of technology, there were many designs that could not be realized. But this undoubtedly opens a new path for these designers.

He smiled and said, "Teacher Nan, what do you think?" ”

Nan Huairen said: "What Mr. Rui said is extremely true, there are many problems that I have not thought about before. I'm a little anxious to go back and look into it. ”

"That's not a hurry. These cannons are also extremely powerful, let's finish the test firing of them first" Kangxi nodded and said, "Chief Rui is a military attaché, and he is definitely inferior to you in terms of technology." He just made his point of view from the perspective of the battlefield. ”

Kangxi is comforting Nan Huairen, the subtext is: I am a **** big country with many talents, if you are not serious, you have to be careful!

"Yes, yes!" Nan Huairen couldn't hear it, and hurriedly agreed.

Then he prepared the two cannons, lit the cannons, and bombarded the mounds in the distance. The hit rate was still good, a total of ten shots were fired, seven of which hit the target, and a cloud of black smoke rose. And if it misses the target, it hits the land, and it can only stir up some loess and turf.

Although there was a hiccup, the power of this cannon was still amazing in this era. It can be regarded as a siege weapon. And Nan Huairen's math is good, so the calculation angle is very accurate, which can ensure a certain hit rate, and Gao Xianda can't help but applaud.

Kangxi felt very satisfied after reading it. But he was now out on patrol in casual clothes, so he didn't say much, so he asked Nan Huairen to prepare the carriage and go home.

At this time, a person came over from the direction of the target and said: "Your fireworks are good, but if you want to call this thing a cannon, I Zhao Ritian is not convinced!" ”

He was dressed in a modern Matt-killing costume, and his hair was not reduced, it was completely a Matt-killing hairstyle, which was incompatible with this dynasty at first glance. Of course, his look is out of place with any era.

Since he does not belong to this dynasty, then he must be a contractor. Gao Xianda didn't believe that his honor would be in the same camp as himself, so he whispered to Kangxi: "Run, there are assassins!" Then he stepped forward and met him.

"This is not the place for you to go wild, get out of here!" Gao Dao first, and then drew the Wind Blade.

"Guards? Your level is not enough to see! The man said as he drew closer.

Gao Xianda suddenly felt a tingling pain in his head, and then he was a little confused. He even felt like his brain was a mess.

"This must be his skill!" Gao Xianda thought. There was nothing polite to deal with the contractors of the opposing camp, and Gao Xianda slashed at him with a single sword.

But Gao Xianda felt a sense of powerlessness in his body, both in strength and speed, which was much lower than usual.

He slashed at it with a swift sword, and the man dodged with a slight flash.

Gao Xianda slashed out two more knives in succession, and even he himself was quite dissatisfied. Naturally, the man flashed over with ease.

"Yo! You're pretty good! There is still the power to fight. The man said to Gao Xianda, "After you die, you can proudly say to others that it was Lao Tzu who killed you: Zhao Ritian!" ”

"Fuck you!" Gao Xianda put the knife back, changed to the attack method he was best at, and swung his iron palm at the opponent.

But Zhao Ritian didn't care, and directly raised a punch and greeted Gao Xianda's iron palm. A fist and a palm collided together, and there was no earth-shattering time when the usual palms were opposed. There was only a "bang" sound, and Gao Xianda was sent flying!

Yes, it was Gao Xianda who was sent flying!

Gao Xianda's strength was as high as 49 points, and his full-level iron palm was unexpectedly knocked away by the opponent's understatement!

Coxenda couldn't believe it was true.

But he flew back a few meters, and he felt as if his strength had returned. With his agility, he flipped lightly and landed on the ground.

Zhao Ritian's fist was actually not very powerful, and it did not cause much damage to Gao Xianda. Gao Xianda's life was only half lost, but Gao Xianda's feeling just now was that the punch seemed to be fatal.

Gao Xianda hurriedly used his strength and recovered his life. Then he rushed at the man again. (To be continued.) )
