Huo Bingyan and Yu Jingqiu's thoughts coincided with Yuan Fang's thinking, which strengthened Yuan Fang's determination, and what he didn't expect before, that is, to increase the range of long-range weapons, this is also crucial, just imagine, if your own air force can carry out effective strikes outside the range of the opponent, then, the enemy will be shot down if they can't get close at all, if you add armor, two-pronged, wouldn't it be invincible.

Xia Yi asked inexplicably: "Brother-in-law, Sister Jingqiu, Bing Yan, what are you talking about?" Yu Jingqiuyun lightly explained Yuan Fang's previous ideas and air combat concepts to everyone in detail, and then talked about his and Huo Bingyan's thoughts, and finally looked at Yuan Fang, waiting for his evaluation.

Yuan Fang pondered for a moment and slapped his thigh fiercely: "Why didn't I expect it, you guys are so smart, this method is good, it's so decided, I'll study it later, and we'll start making armor tomorrow." ”

Yu Jingqiu was pleasantly surprised: "Really? Can we really do it? ”

Yuan Fang nodded heavily and said firmly: "Absolutely." Yu Jingqiu and Huo Bingyan were overjoyed when they heard this, not because of the praise, but because they were the happiest to be able to help Yuan Fang.

Yuan Fang's words gave all the credit to Yu Jingqiu and them, firstly, to encourage everyone to actively use their brains, and secondly, they don't care about the credit or anything, but for Sang Rou, it is different, there is a reward for merit, it is difficult for them to be promoted by their side, so they can only accumulate meritorious service from other ways, this is a good opportunity. Yuan Fang's affirmation is the best encouragement.

Next, everyone joined the discussion of armor, through Yuan Fang's secret guidance and fueling, and finally decided to use multi-layer composite armor, this armor has five layers, the inside and outside two layers are the thinnest iron sheets, and then there are two layers of rubber plates, and the middle is a layer of basha wood with a thin iron bar frame, and the five-layer buffer structure should be able to greatly slow down the impact kinetic energy of the arrows, of course, it is only theoretically feasible, and the specific effect has to be determined by actual verification.

Next, we will discuss the range of weapons, this cold weapon world, there is no musket, the long-range attack means is mainly the bow and crossbow, the range of the bow and arrow is limited, and there are not many archer with strong arm strength, then, the only thing that can meet the requirements is the strong crossbow of the mechanical winch, this kind of weapon is available in every country, Yuan Fang They are not experts in the development of weapons, and there is no better improvement suggestion, so they retreat to the second best thing and make a fuss about the crossbow arrow.

The discussion soon had a result, based on Sang Rou's experience analysis, the metal arrow body of the crossbow can be changed to an ordinary heavy arrow, which is the kind of ordinary arrow with a slightly larger arrow, the advantage of this heavy arrow is that the range is longer, the penetration is stronger, the stability is better, of course, the requirements for the archer are also higher, but there is no problem if it is launched through the strong crossbow.

Yuan Fang also made some adjustments in the arrow, changed to a cross heavy arrow, this kind of arrow has limited penetration of the human body, but if you shoot an airbag with weak defense, the cross-shaped arrow will cause huge destructive power, tearing a big hole in the airbag, which is definitely the nemesis and big killer of the aircraft.

Early the next morning, the soldiers divided into two routes, Yuan Fang and Sang Rou stayed at the base to make synthetic armor, Guan Xiaoyun, Ouyang Xianxue and Xia Yi went down the mountain to the defenders to get various types of strong bows and crossbows.

The materials of the base are complete, thin iron sheets, rubber sheets and basha wooden boards are ready-made, as long as the interlayer is smeared with glue and fixed with rivets.

Yuan Fang made a two-meter square deck, measured the weight, it was still done, it was not very heavy, and the buoyancy of the fog should be able to move.

Guan Xiaoyun's side was also quite smooth, and he soon came back with more than a dozen crossbow carts and bows and crossbows, along with matching arrows, and several carriages were loaded.

Looking at Guan Xiaoyun, who was returning with a full load, Yuan Fang was stunned for a while and said, "I said, how did you kid get so much?" ”

Guan Xiaoyun shrugged: "I'll go find Ren Chang, he heard that you want to borrow a heavy crossbow and threw these to me in one go, and I can't help it, so I pulled them back." ”

Xia Yi snickered and said: "It's still my brother-in-law's big face, and people gave so many heavy crossbows without asking, this thing is a good thing, and it is generally not given away." ”

Yuan Fang rolled his eyes: "It's useless for me to ask for these, just borrow them to study them, and I have to return them when I run out, otherwise if those old immortals know about it, they won't suspect me of rebellion." ”

Yu Jingqiu covered her mouth and smiled: "Rebellion? Just these things? ”

Lin Mengsheng came over and said in surprise: "Boss Yuan, you want to rebel?" Everyone was speechless, and gave the thing a middle finger to roll as far as he could.

In a blink of an eye, more than ten days have passed, Yuan Fang and his entourage packed their luggage and prepared to meet the imperial capital, this time, Lin Mengsheng went back together, this kid has not been home for half a year, and he should be allowed to go back to see, as for the other craftsmen, the empire with family members sent people to take their families to the base, so that everyone can have a reunion year, of course, these people will always live here for a period of time in the future, do what they can.

Yuan Fang and Lin Mengsheng are gone, the work of the base continues, after this period of efforts, the design of the small boat has basically matured, and it is in the fifth test flight stage, if there are no problems in the future test flight, then it can be determined that the structure is mass-produced.

The dinghy is an air combat unit designed by Yuan Fang, it has a petite stature, similar in appearance to an airship, but it looks a little bloated, this bloated is not to say that the volume is huge, but the structure is very compact, in addition to the airbag and the lower cabin, a deck is also installed on the airbag, on which four ballistas of the latest design are placed, plus two on both sides of the cabin, a small boat is equipped with six ballistas, and the firepower is absolutely amazing.

The ballista is a new generation of heavy crossbow named by Yuan Fang, and its essence is still a heavy crossbow, but some adjustments have been made, removing some unnecessary objects, or replacing some heavy metal parts with hardwood to reduce weight, and the same is true for the crossbow body, only the crossbow groove is wrapped in iron sheets, which increases the wear resistance and reduces the friction when the crossbow arrows come out of the hall.

The ballista bolt is seventy-five centimeters long, the arrow body is made of hard mahogany, the arrow cross shape, made of alloy, the destructive power of the airbag is extremely strong, as long as this crossbow arrow is shot is a cross-shaped big breath, the fog will pour out quickly through the gap in large quantities, causing the aircraft to lose buoyancy and power to drop rapidly, if the damage is large enough, the aircraft will immediately lose control and fall.

In terms of range, because the weight of the arrow is reduced, the initial velocity is increased, and the range has also been improved, but not very much, because the weight is reduced, the stability of the arrow is greatly reduced, which limits the accuracy, resulting in a sharp reduction in the effective range, but Yuan Fang is already very satisfied.
