Looking at the more than two dozen cannonballs tied, Ding Bu's eyes lit up: "Dean, will you finish all these cannonballs in a while?" ”

Yuan Fang smiled and said, "Of course, let you fight enough today." ”

Ding Bu said excitedly: "Great, we have to have a good time today, Yuan Fang, will we go to the high seas in a while?" ”

Yuan Fang was surprised and said, "What are you doing on the high seas?" ”

Of course, Dingbu said, "Fighting." ”

Yuan Fang rolled his eyes: "If you don't go to the high seas, just try it in the annex." ”

Seeing the disappointment on Ding Bu's face, Yuan Fang comforted and said: "Don't worry, artillery is our secret weapon, and we can't let the enemy know it now, otherwise we won't be able to achieve the unexpected effect. ”

Ding Bu sighed, "Oh, I see. The airship took off, and Yuan Fang and the others did not take the airship, but were driven by the red clothes to follow Ding Bu's fighter jet in a small boat.

After leaving the Long Roundabout Island for about ten miles, Ding Bu received the order and began to test the artillery, while making various difficult flight maneuvers, jumping up and down in the air.

With the sound of cannons, or a large scatter projectile is shot into the sea, exploding in the air not far from the sea, or a black dot falls into the sea and explodes, setting off a huge wave.

After more than a dozen shots, Ding Bu's fighter suddenly fell silent, and after inquiry, what Yuan Fang was worried about happened, the strong upward recoil caused the ground of the fire compartment to be damaged and cocked, and it was impossible to continue firing.

Ordering to return, Yuan Fang looked at the situation on the ground of the fire cabin, and was afraid for a while, fortunately, the ground damage was not too serious, otherwise several artillery soldiers would have to fall.

Leaving Ding Bu and them to repair the fighter, Yuan Fang pulled the cannon back and came to the blacksmith furnace again to redesign the mold.

I didn't close my eyes all night, and the next day when it was almost noon, the second-generation artillery was freshly baked, the second-generation artillery was slightly thinner than the first, but it was more slender, the barrel was a foot longer than the previous one, and the caliber and shells were also relatively smaller, from the previous football size to the size of an ostrich egg, and the volume was almost halved, but the shell shell was much thinner than the previous one, and the explosives contained in it were not much different, and if it succeeded, the power of the shell would not be too bad.

At the same time, the shell shell has also been improved, and the irregular lines are outlined on the mold of casting, so that the shell that is poured has a texture, and the shell is divided into pieces the size of a fingernail, such a design is to improve the lethality of the explosion of the shell, the previous shell is a little too thick, and the shrapnel after the explosion is almost half an egg size, and now once this shell is exploded, it will explode into a thin iron sheet the size of a fingernail, which is stronger in terms of quantity coverage and density and lethality.

Similarly, Yuan Fang pulled the second-generation artillery to the beach for test firing, more than 20 shells were lighted, the effect was not bad, although the caliber was small, but the range basically did not have much impact, Yuan Fang analyzed, this may be related to the length of the barrel, but he can't be sure if the truth is so, and it needs to be verified later. There was no time to have dinner, Yuan Fang and the others pushed the second-generation artillery to the airport again, today it was more lively than yesterday, the doors of the hangar were open, and the pilots and ground crews were maintaining their airships.

As soon as Yuan Fang arrived, Xueqin greeted him: "Brother-in-law, you came just in time, I was about to look for you." ”

Yuan Fang's heart tightened: "What's wrong?" ”

Xueqin smiled and shook her head: "No, it's not that you said that you have to give you a battle report after every time you leave the station, I just sorted it out." As he spoke, he handed a file to Yuan Fang.

Yuan Fang breathed a sigh of relief, opened it and looked at it, and said with satisfaction: "Not bad, three to eleven." ”

The so-called three to eleven means that the other side loses three boats and the other party loses eleven boats, and Yuan Fang is quite satisfied with this ratio: "By the way, how about the casualties?" ”

Xueqin restrained her smile: "This time I lost two pilots and one gunner, and the others were not in danger of life, but only slightly injured." Yuan Fang nodded slightly, such casualties were still bearable.

Xueqin remembered something, and said with some amusement: "By the way, brother-in-law, the Liusang Empire is also studying parachutes, but they have just started, and the parachutes they have come out of are nondescript, I have seen with my own eyes that many airships jumped out after they were destroyed, but their parachutes either couldn't be opened or half opened, only one or two succeeded, and the rest fell directly to death." ”

Yuan Fang smiled and said proudly: "Not everything can be imitated, without the correct storage method and umbrella opener, they will fall to death more people." ”

Xueqin glanced at the artillery behind Yuan Fang: "Brother-in-law, do you want to test fire again?" ”

Yuan Fang nodded: "Ding Bu is not there?" ”

Xueqin shook her head: "He has a patrol mission today, not here, brother-in-law, I'll come." ”

Yuan Fang hesitated for a moment and said, "Okay, be careful." ”

The second-generation artillery was installed on the fighter, and the butt and gunpowder were all moved to the fire cabin, and Xueqin personally piloted the fighter into the air, and Yuan Fang and the others were still dressed in red, driving a dinghy to follow. The test firing went very smoothly, and all the 30 shells carried were all exhausted without any problems, and when he returned to the airport, Yuan Fang carefully and carefully inspected the fire capsule, and then asked the gunner some questions, and Yuan Fang was very satisfied with the answers.

The caliber of the second-generation artillery has been reduced, and the recoil has also decreased, so that the fire compartment of the fighter can withstand it now, and according to the artillerymen, this kind of artillery is more accurate than the previous one, this statement Yuan Fang could not verify, he did not know whether the so-called accuracy was due to the results of the artillery training or the improvement of the accuracy of the artillery itself.

The next day, the blacksmiths made two new cannons, both of which were loaded by Yuan Fang on the fighter planes, and tried for a whole day, until all the shells were exhausted in the evening.

After a day's testing, the basic safety and practicability of the artillery were determined, and Yuan Fang no longer hesitated, and immediately sorted out detailed drawings, indicating the dimensions and materials of each part, and then spent a night redesigning the structure of the fighter according to the opinions of Ding Bu and Xueqin.

Yuan Fang also asked someone to bring a letter to Yan Xiong, telling him to make every effort to manufacture the second-generation artillery and the supporting various artillery shells, as well as the cartridge butts and bomb shells, as for the first-generation artillery, twenty guns were temporarily customized, Yuan Fang thought so, first arm the air force, and then consider the issue of the navy after the air force is equipped with artillery.

As for the fighter, of course, it can't be delayed, Yuan Fang's latest design only slightly adjusts the fire capsule, removing the previous left and right direction firing ports, and only retaining the front and rear directions.
