Intelligence is beyond the reach of ordinary people, to a certain extent, it is equivalent to one in hundreds of millions of miles, Zhang Fan, at this occasional situation, of course, saw some clues that are difficult for ordinary people to see. If you don't have the most basic cultural skills, it doesn't matter, when Zhang Fan at this time can be regarded as having some cultural skills, and when he thinks about it again, he seems to have quickly come up with some problems that are difficult for ordinary people to think about.

"I think maybe we should do some testing? let the crossbowmen try it! Lift the crossbow machine high, not too fast, use a heavier arrow, and see if everything is as I thought... ”

Zhang Fan, who also had some experience in the use of hidden weapons and even projection weapons, decided to conduct a series of tests at this time, preparing to summarize some rules that he seemed to be able to feel ignorantly. At this time, Zhang Fan seemed to be beginning to realize some problems: the unity of weights and measures, to be precise, a more precise unity. There is also a more accurate way of timing in a short period of time is very important...

At the beginning, Zhang Fan didn't have a good idea, but it didn't take too much time, and he still prepared a fast water leakage timer, a scale that can calculate the weight more accurately, and the best preserved line ruler. These are things that only some of the top craftsmen have.

Subsequently, Zhang Fan began to seriously carry out the research on the special large-scale crossbow arrow arrow under a certain power and speed standard. Moreover, Zhang Fan also gradually gave a set of methods for measuring recoil. In particular, Zhang Fan found that if the crossbow machine was hoisted up and shot. The entire crossbow swings backwards under the backseat at a height that appears to be roughly similar to that of a target object of the same weight. If the weight of the target object is significantly smaller, it will be higher, and in this way, some simpler techniques for measuring momentum will emerge. Under Zhang Fan's guidance, rich apprentices and even craftsmen who were gradually interested in these things and had some culture gradually summed up some more perfect rules.

"The path of a crossbow arrow after it is fired should be about the same as the speed at which it falls from a fixed height. The corresponding height on the aiming line is often the time it takes to fall to the height, at least not too far from the left and right. ”

In this way, many related things have become more and more clear, and the more intelligent Zhang Fan has seen a lot of things from the experience of those apprentices and craftsmen: the distance of the fall seems to be a multiplication of time and then multiplied by a certain constant?

There are very few arithmetic masters in this world who are good at calculating the art of reverse multiplication, at least at this time, there are no people around Zhang Fan at all. But when Zhang Fan decided to use his power to find it, he finally found an arithmetic master who was said to be quite famous. In this way, many seemingly difficult things will be solved.

After this round of archery innovation, which started with manufacturing and standard innovation, the mentality of many overly pessimistic veterans and even craftsmen has quietly changed. In the end, when the more mature actual combat tests began to be completed, many people could roughly see at this time: even a person who is proficient in this aspect of arithmetic cannot achieve the accuracy and quality of those veteran crossbowmen who have more than ten years of operation experience after a month of practical training, let alone the ability to react to battle. But there is no doubt that the difference is not worlds apart. If you have a year or two of relatively substantial training, or a few years of less substantial but basically qualified training, these people can become very good crossbowmen in terms of organizational skills.

Of course, in this process, Zhang Fan also found some problems: when operating a giant cylinder gas crossbow to aim at some targets that are likely to move quickly, it is still too difficult for these ordinary people. This must be reduced as much as possible, at least in operation...

Therefore, in the following period, some of the more outstanding apprentices and the "Core Breakthrough Academy" tried to improve the operation of the entire cylinder gas crossbow in various ways.

At first, people found that even if they used a perfect two-way wheel and gears to operate this cylinder air crossbow, it was still a bit clumsy, and it was not specially selected to have outstanding physical strength and even quick eyes, and it was still impossible to compare with those outstanding crossbow veterans. However, Zhang Fan, who was not stupid, quickly thought of another way: Can we also use cylinder gas power to complete some basic operations? Personnel are only responsible for the control of the entire steering braking? Of course, some people have proposed some methods from other angles: such as using special weights, like breeding trebuchets, using gravitational energy to accelerate the steering.

At the beginning, there were many problems in the trial production of the new cylinder gas crossbow steering device, but with the continuous trial and improvement later, it seems that a group of people who are not too skilled in operation can finally be allowed to have some very experienced crossbow veterans in effective operation practice. Especially against some of the close-range, it is clear that they still have the upper hand.

Of course, Zhang Fan himself is not worried about this kind of progress, after all, for himself now, he can already deal with a large area of opponents and targets at a distance of about three miles. At a distance of about two or three miles, even if the heavy arrows are as dense as flying locusts, there is not much danger to me now. Unless there are that kind of unique Distant Arrow Gu among the dense heavy arrows. However, unlike other Gu worms, the reproductive performance of the Yuanman Arrow Gu was very poor, and it was unique to some extent. If some people try to use that method against themselves, it should not be effective.

Of course, even so, even after a series of breakthroughs under his leadership, Zhang Fan still didn't have much confidence in these people who were completely incomparable in courage with the kind of army he encountered in Zhongzhou.

If one or two or a few second-rate people like themselves are just wearing armor and shields and not having their own level of long-range spells, it is still very dangerous to deal with 100,000 or tens of thousands of truly excellent heavy gas crossbowmen. But if it is a team of several first-class martial artists, plus a dozen second-rate masters, and more third-rate masters. The strength of tens of thousands to 100,000 excellent and sophisticated crossbowmen is also obvious, and it is a little insufficient. At that time, the Eastern Plains Kingdom was able to put pressure on the Xishan Jianghu Realm, and in addition to the million-level army, it was also possible to achieve this to a large extent with a lot of poisonous means. Relying only on "net arrows" will not pose much threat to some real masters.

Zhang Fan is also worried about this to a large extent. Especially in the process of confronting certain forces, many poisons and even Gu things have been eliminated by themselves. And another concern is that Zhang Fan himself is not good at this, and it is difficult to guarantee that if he plays this set, he will not bring danger to himself.

Therefore, at this time, Zhang Fan also launched a "reward order" after he was busy with a round of innovation climax about cylinder gas crossbows, soliciting ways to improve his combat effectiveness. Of course, Zhang Fan understands that only when ordinary people themselves can master the force that is at least capable of confronting those Jianghu people through some unique method, perhaps a real change in the social structure can occur.

There are not a few smart people selected by Zhang Fan, and under enough pressure and motivation, there are also many people who have proposed some methods that seem to be like that.

For example, it has been suggested that a unique bellows-like spray canister can be pushed by means of heavy energy or cylinder gas, so that the nozzle can violently spray the oil far enough. If there is a burning flame igniting the oil, it is an effective flamethrower.

At the beginning, Zhang Fan also thought that this idea was very good, and only urgently solved the problem of "what to do in case of melee combat". It was only not long before another possible hidden danger was raised from a hostile point of view: what if the other side used smoke for cover? If you take this into account, it seems that the "firepower" is still not very sufficient?

Others put forward more ideas: for example, in order to maximize convenience and flexibility, cylinder gas crossbows could be less large and deploy some single- or double-shot disposable crossbows that can be operated flexibly and conveniently, but this is largely clear that it does not solve the fundamental problem.

After obtaining a lot of combat effectiveness methods, Zhang Fan felt somewhat disappointed, because although some of these methods did have the potential to increase some combat effectiveness, they could not fundamentally improve the combat effectiveness pattern.

Of course, Zhang Fan at this time is not a rare genius, after many days of meditation and meditation, he suddenly thought that he had accidentally seen a different kind of artist snack when he was wandering in the rivers and lakes, which seemed to be called popcorn. Guess how popcorn works, is this possible? A more sturdy container is filled with a liquid like water, which is heated continuously, or some kind of cylinder gas. If you blow up the chamber under calcination, you can make one of them weaker. In the case of reaching a certain critical state, as long as it is suppressed by some external force, it is easy to break and explode, so that the violent gas and liquid will form a more effective driving force?

Zhang Fan's initial idea was of course extremely simple, and he didn't know what kind of details he could really use it efficiently. It's just that when these things really became a kind of subject with a lot of rewards, they were quickly overcome with the help of brainstorming. A person who has learned a lot from the blacksmith and has a more flexible mind asked: If one end of a cylinder container that has been subjected to high heat pressure suddenly comes into contact with something relatively cold, such as cold water or cold liquid, will it be damaged due to the sudden reduction of its bearing capacity?

Some people have put forward some other different ways of thinking: some inflatable devices can be designed according to the principle of cylinder air crossbows, which do not necessarily require hot pressing, and heat will reduce the strength to a large extent, and even at this time, some more prominent geniuses also proposed the principle of air cannons.

Zhang Fan was not completely sure which directions were feasible, so he gave a lot of "project teams" a few months of time and even a certain scale of manpower and material resources to explore and trial production.

The people with hot bottles soon ran into more and more trouble, and in several accidents there were more than a dozen deaths and injuries, which greatly dampened people's emotions. However, the people who studied the air cannon finally relied on the abundant skilled craftsmen inherited from the Dongyuan Kingdom by Pingyang New Town at this time, and it seemed that they were becoming more and more reliable, and Zhang Fan also had a feeling that he had found the right direction.

In order to produce results in a relatively fast time, Zhang Fan quickly concentrated the best talents and material resources that he could gather in his hands to invest in this direction after figuring out the roughly reliable direction, and then in the following half a year or so, after many tests, the performance of the new air cannon also began to stabilize to some extent.

Compared with the best bed crossbows, the muzzle velocity of this air cannon is increased by about 50% at the same weight, the power is more than doubled, and the overall effectiveness is increased by as much as three times. If you take into account that this kind of thing is much better in terms of relative difficulty reduction in manufacturing and service performance, the real efficiency increase may be about five times.

In this way, if such weapons are truly large-scale and army-oriented, bringing about a multi-fold increase in combat effectiveness, then many things that were not certain in the past will gradually become certain. Perhaps tens of thousands to 100,000 elite air artillery soldiers will still not be able to defend against the Jianghu people of a certain size that they have conceived, but what if more troops and labor force are mobilized? What if more chariots, horses, and even spare cylinders and tools are prepared? If we look at it this way, the potential for improving combat effectiveness will be ten times greater than several times. In this way, many things begin to see the light of day rather than not seeing the light of day.

Not only Zhang Fan himself, but also many smart craftsmen have begun to realize this. The gloomy mood of the past was finally swept away at this time, and after more and more people understood the direction of progress, the negativity of many people in the past gradually disappeared, and the progress of combat preparedness also developed at a speed beyond Zhang Fan's imagination.

Moreover, Zhang Fan soon discovered that when this air cannon is used as a means of projection, there is a lot more room for choice in the projection weapon itself. Many people have even put forward some new ideas for sub-mother arrows, although this kind of thing cannot fundamentally increase the projection ability, but it can obviously interfere with the fundamental judgment of some masters, and can make people unguardable. In this way, what was only a defensive chance in the previous estimate has become a real confidence and chance. The impossible victory has gradually become possible in the real sense under the preparation and exploration led by Zhang Fan.
