But anti-aircraft machine guns are also only a solution to the problem of whether there is a problem, and the most effective means of dealing with an air enemy will always be another air weapon.

In the era of the Federation, this was usually done by witches.

The few capable of soaring into the sky, plus the few extraordinary witches who wear flying magic stones, are the most elite fighting force in the Federation. Although this unit is part of the Holy Blessing Army, it has a higher status than the other battle witches, and according to Pasha, the three successive seats of the Federation have come out of this unit.

For humans with mediocre talents, who are neither capable nor able to use magic stones, the only thing they can rely on is their brains and hands - replacing wings with equipment, getting rid of the shackles of gravity, and lifting their heavy bodies into the blue sky is the right way forward.

In order to gain air supremacy, Neverwinter must assemble its own flying forces.

He needed to make real airplanes.

However, Roland also knew that he still had several difficulties to solve to this goal, and even the ancient World War I biplane was a complicated thing for him - no more than the simple power take-off and braking system of the train, and the several movable rudder faces of the plane alone were enough headaches. Crucially, he had absolutely no experience in maneuvering aircraft, so he was not sure if the mechanics would work.

Fortunately, the glider program can fill this gap to some extent.

Wendy, who can accurately sense the direction and force of the wind, is undoubtedly the best test pilot, and with the protection of Lightning and Maisie, he at least does not have to fill out a set of control manuals with human lives.

"Your Majesty," the Diffuse Star Scholar's reply pulled him out of his thoughts, "I have received your will, and this observation instrument arithmetic academy will make it for you as soon as possible." ”

"Good. Roland nodded in satisfaction, thinking that it would be the right choice to pack up the entire astrological association and pull it to the west. As long as he explains the principle, the other person will be able to figure out what exactly he wants.

What's even more reassuring is that the astrologers are no less hands-on than they are math-solvy, after all, blacksmiths don't know how to make a perfect stargazing scope, and most of the equipment is ordered and assembled by themselves. It seems that as a science of sages, the astrological society is not much more disgraced than the alchemy society.

Just as he was about to leave, the Diffuse Star Master seemed to be a little speechless.

"Anything else?" asked Roland.

"That's so, Your Majesty," the maester coughed twice, "and I've always had a little bit of an idea...... Why is the word intermediate on the cover of this book of analytic geometry, and on the math books you gave me?"

He couldn't help but chuckle, "Just want to ask this?"

"Please forgive me for being abrupt if it is inconvenient to disclose. "Unlike Kemo Stell, the Diffuse Star, who has been in the capital since birth and has served several kings, is obviously much more disciplined. Just from the look in his eyes, it could be seen that he was not much less curious about this matter than the chief alchemist.

Roland couldn't help but laugh at the thought that he had tied Kaimo to the carriage of Neverwinter with a copy of "Medium Chemistry", that he had been an apprentice, and that he had been the Minister of Chemicals. However, a person as polite as the star of the Mass naturally did not need to hang him.

"Because on top of that, there's another subject called Advanced Mathematics. It is not pure geometry or arithmetic, but a collective name for all advanced mathematical theories. If you were to take the elementary and intermediate books I gave you as the trunk of a tree, advanced mathematics would be the branches and leaves stretching out above, but this subject is too difficult...... So it has another name. ”

"Yes...... What?"

"From getting started to giving up. Roland said.

Diffuse Star's eyes widened, obviously unable to understand the laughter of these words, "Your Majesty, Your Majesty...... I'm not going to give up! Even if I dedicate the rest of my life, can you give me a look......?"

For some reason, seeing the other party's appearance, Roland suddenly felt a little weak because he had dozed off in high math class in the past, and he cleared his throat, "Of course, when you finish this work, come to the castle to get the books." ”

"Yes, Your Majesty!" said Diffuse Star, kneeling down excitedly.

......

Leaving the arithmetic courtyard, Roland turned around and went to the backyard of the North Slope Mountain.

In addition to the anti-aircraft machine gun, he plans to set up the equipment of the Witch of Divine Punishment as well.

After months of getting along, he had determined how vengeful the remnants of Tachira were against the Devil, and if Neverfell was determined to fight the Devil because they would die if they did not resist, then their obsession was beyond survival. In the minds of ancient witches, the devil is the source of their centuries-old suffering, the enemy of their loved ones and friends, and the nightmare of their best wishes.

And it would be a waste to let such a group of warriors with strange powers use swords and spears to fight the devil - for weapons that are difficult for ordinary soldiers to carry, they can carry them with them, which means that the combat efficiency of the Divine Punishment Witch is also several times that of ordinary people, which can be described as the most ideal individual heavy fire support unit.

Roland's original idea was to design a portable Mark 1 heavy machine gun, with a knapsack magazine, so that the Witch of Punishment could be turned into a free-moving turret, no matter what kind of devil it encountered, and sweep hundreds of rounds first.

But now he has changed his mind.

Nowadays, some heavy machine guns need to be diverted for anti-aircraft machine guns, and with the newly produced Mark 1, it is foreseeable that the rate of consumption of bullets in the future will definitely be like running water. With Neverwinter's current production capacity, he simply couldn't handle bullets as if they were something he didn't need money for. If you prepare another 300 for the Witch of Divine Punishment, it is estimated that it will be difficult to replenish the corresponding ammunition, and if you have to stop and save bullets after firing a few shots, it is equivalent to losing the meaning of moving the battery.

Therefore, it is best to use a new weapon as a large firearm with high power, low consumption, and at the same time simple structure and easy maintenance.

Roland quickly drew its prototype on paper.

An automatic shotgun with a caliber of 40 mm and an air recoil.

The advantages of the shotgun are very distinct, no need for accurate shooting, wide killing range, caliber can effectively improve the shooting distance, automatic firing is to strengthen the characteristics of fierce fire, not only can be used as a revolver, bolt-action rifle supplement, quickly eliminate those who break through the artillery blockade of the enemy, but also can be used in surprise warfare, actively approaching the target to ambush.

At least during the Second War of the Divine Will, hand-to-hand combat was still the Devil's primary method of warfare. Even in encounters, there is a high probability that the mad demon will not choose to throw a bone spear, but will rely on hand-to-hand combat to determine the winner.

At that point, the Witch of Punishment, armed with an automatic shotgun, is sure to make her opponents suffer.

......

Five days later, Sylvie spotted the dinosaur again.

And this time, the number of enemies doubled. Twelve dinosaurs struck like a cloud, heading in the direction of Neverwinter.
