By the time we returned to the fortress, it was already midnight, most of the people had already fallen asleep, and only a few were still standing.

"Hmm, welcome back, how was the mission done?" Looking at the few people who staggered down from the cabin, Goode straightened up and asked.

"A bumper harvest, however, the situation is terrible." Karel patted the hard ore bags hanging on his waist and said with a gloomy face.

"What did you find?" Looking at Karel's expression, Goode also knew that things might be a little harsh.

"The Abyss Demon King, an Abyss Demon King in the Sin Capital, and most of the guards and workers there are reformers, a bit like Morgo's style." Karel briefly recounted what he had seen.

"The Burning Legion." Goode touched his chin and pondered, "These guys are really everywhere. ”

……

Tong! With a muffled thud, Karel collapsed straight onto the fluffy bed.

"What, are you so tired from going out for a few days?" Looking at Karel's appearance, Lulin asked, smearing an emerald green ointment on her face.

"Yes, I met an Abyss Demon King and fought one, but it wasn't a big deal, guess who I met later." Lying on the bed, Karel's voice was muffled.

"Who?" Lu Lin rubbed it lightly on her face, and the emerald green ointment was quickly absorbed by the skin, making Lu Lin's face look extraordinarily fair and supple.

"Salina." Karel said.

"Who?"

"Salina, and O'Lelar. and Estrid. "They have a lot of opinions about me. ”

"Did you mention me?" Lu Lin sat on the bed, pressed one hand on Karel's back, and asked with a little concern.

"Of course, they asked me what kind of psychic soup I poured on you and got you away, and then said that they miss you very much and want you to see you in the old place in a month and a half, but they didn't say what the specific activity was." Karel rolled over and said as she looked at Lulin's pretty face.

"A month and a half later, oh. All right. Would it be okay to go together then? Lulene thought for a moment, as if she remembered something, and then leaned down with her tail wagging and her soft palm groping over Karel's chest.

"Of course. Gladly so. Karel smiled and hugged Lulin.

……

This time out. Harvested 5 boxes of Hengjin. A total of 128 tons, 187 boxes of magic iron, a total of 1,870 tons. If a flying machine survives, it only needs two hundred to three hundred kilograms of magic iron, and all of them can be made into a flying brigade.

With the materials, the rest of the things are easy to do, make the magic iron ingot into the magic iron screw, the magic iron shell, plus the star wood used to make the propeller, and the elemental explosive powder used as fuel, these are the main materials used in a flying machine. In other words, the goblin product is such an IMBA, and even the fuel is so non-mainstream.

"Squeak! Boom Boom! ”

"Squeak! Boom Boom! ”

"Squeak! Boom Boom! The next day, in the open space outside the fortress, Karel was sitting in a freshly made flying machine, scrambling to light a fire, the problem was that the thing couldn't be lit, and the other onlookers around were already whispering.

"Nima!" Karel couldn't stand it anymore and smacked the engines on both sides, then ignited again.

"Whew! Boom Boom!! This time, the ignition was successful, and the rotor spun quickly.

"Well, pull up." Karel slowly stepped down with his left foot, the propeller getting faster and faster, and then gradually flew off the ground with the aircraft.

Looking at Karel in mid-air, the onlookers on the ground cheered, which means that they will also have a chance to soar in the sky in the future!

About this aircraft,It's actually very simple,The pedal of the left foot controls the lifting of the zhì,The joystick of the finger controls the direction of the flight,The rest is gone,The maximum flight altitude is 1000 meters,The maximum flight speed is 150 meters / s,Overall,The performance is okay,After all, it's a bargain。

After the successful test flight, the next step was to equip it with weapons, and drove the aircraft back to the engineering workshop, Karel gathered some mercenaries who had studied engineering, and everyone brainstormed how to make the most of this flying machine.

After a long discussion, the plan was finally finalized.

This kind of aircraft is not the same as a helicopter, the helicopter is powered by the main propeller, and the tail rotor is kept stable and cooperates with the action, but the aircraft does not have a tail rotor, instead of an engine on the left and right sides, which works at the same time to maintain the balance of the aircraft and the forward power, and has the function of turning.

In this way, the width of the aircraft is a bit large, about 2 meters, but you can also take advantage of this.

The 7.62mm caliber multi-barreled Gatling gun, which is Karel's latest support weapon, can reach a rate of fire of up to 6000 per minute, making up for the lack of power with a rate of fire.

The two machine guns are fixed on the outside of the engines on both sides of the aircraft, and the muzzle pointing can be adjusted vertically, if you want to strafe left and right, you can only let the aircraft turn left and right, and the aircraft equipped with multi-barreled machine guns has a width of 2.3 meters, but it is still worth it compared to the powerful firepower.

Under the plane, there is a pair of landing gear, in the middle of the two landing gears there is a large distance, in this regard, the result of the discussion is to lengthen the landing gear appropriately, increase the angle of the two landing gears, and then add a honeycomb rocket launcher in the middle of the landing gear, it is completely possible to bomb close to the ground, under the premise of ignoring accuracy, each aircraft has extremely strong firepower.

As for the supply of ammunition, each aircraft can be loaded with 3 engineering boxes, each of which has a volume of 32 compartments, enough to hold more than 60,000 rounds of ammunition and more than 300 rockets, and can also stuff the aircraft with fuel into the engineering box, and its endurance will no longer be a problem.

And each aircraft is equipped with a pair of engineering eyes, the effect of this glasses is to measure the current altitude, speed. And auxiliary aiming, although Gatling does not pursue accuracy, but it also needs to hit the target.

After the design was finalized, production began, but it was not enough to have an airplane without people, so everyone was surveyed in the fortress.

As a result, all the physical professions showed great fanaticism, while the French professions were of mediocre interest, which is not difficult to understand, and the French profession itself was equivalent to a large-caliber artillery with unlimited ammunition. Once you have mastered the elemental resonance, you can fly in the air. As long as the shield can withstand it, it is still possible to fly one or two hundred meters per second, but the attitude of the mixed class towards flying machines is a bit wavering.

For example, Paladin, Paladins have ranged attacks. But the main thing is hand-to-hand combat. Can fly after mastering Vengeful Wrath. But it can only be a sprint flight, and they can't fly far at all wearing heavy plate armor, otherwise they will be exhausted to death. All they were struggling with. Whether you want to use this kind of thing or not.

There is also a strange druid, the druid is the earliest profession that can fly, if you specialize in transfiguration, you can turn into a flying eagle very early, soaring in the sky, but the druid's long-range attack form is a beast, also known as a goo, quail, when Karel investigated those elven druids, one of them performed a druid's air combat method for Karel.

First of all, first turn into a flying eagle and fly to the sky, then turn into a beast, attack with a spell, and after the attack is completed, it will become a flying eagle and continue to fly forward, so the two forms switch back and forth.

Although it seems to be quite effective, Karel always feels a little painful, and I wonder if it is because she played too much with Lulin last night.

After the investigation, Karel discussed with Goode and set the internal price of the aircraft at 40,000 gold coins, which was just enough to empty the pockets of most of the mercenaries in the fortress.

After all, the mercenary captain is not a philanthropist, and this price is basically given away for nothing, and those mercenaries also know this, and they have no complaints when they pay for it, but they just watch the money bag full of gold coins disappear into their hands with tears in their eyes.

For this flying machine, the elves also showed great interest, in Imis, most of the air forces of various countries are composed of various flying monsters, such as dwarves and human griffins, flying eagles, elven chimera, orcs bipedal wyverns, and humans, the growth cycle of these animals is very long, each from the cub to maturity at least 5 years or more, and in the process of growing up, it needs to go through a lot of training, because of the harshness of training, Not every cub can grow into a qualified air combat beast, besides, this kind of creature is usually very powerful, and strong means that it is difficult to give birth, and a litter is only 2-3 litters at most, which causes the air knights of each country to be unusually rare, so the air knights are usually the best and most elite troops in each country.

And this mechanical creature in front of him, even from the most demanding point of view, is the most suitable main force for air combat, and there is no one.

The cost is low, the manufacturing speed is fast, the operation is simple and convenient, the attack lasts for a long time, the power is large, and the flight time is also very long, in addition to the slightly inferior flexibility, it can completely explode most of the current flying arms in the world, after all, no matter how strong the Chimera knight is, it is only flesh and blood, and the armor assembled is only light armor, even if there is the blessing of magic, it is simply unable to withstand 12,000 beats per minute, comparable to the rapid attack of a giant crossbow.

Buy, buy, buy! At this moment, those elf buyers turned into Tao. Unable to suppress the desire to buy, the treasure chopper went to ask Karel about the price of the flying machine.

"You want to buy flying machines, too? Aren't the Elven Chimera forces very famous throughout the continent? Karel, who worked in the real workshop, turned his head and looked at the price buyer in surprise.

"It only takes 7 years to raise a Chimera thing, which is too long, and the care conditions for the cubs are extremely harsh, and the mortality rate is very high, the Elven Empire invests a huge amount of resources in the Chimera army every year, but more than ninety percent of the funds are wasted, in fact, we have long wanted to replace it." A couple of elf buyers said.

After some negotiations, Karel and the group of buyers had a dispute over the price, and Karel quoted 1 million gold coins for a flying machine, and the purchase should not be less than 100 at a time.

But for this price, the original buyers were unwilling to agree, they were too expensive.

"Too expensive? Okay, if a flying machine needs to use 260 kilograms of magic iron, elemental explosive powder and star wood, we will do without it, just look at the magic iron, then we will calculate it according to the market price, and we don't even need processing fees, what do you think? If you provide a processing fee of magic iron plus 1,000 gold coins per rack, we can also help with the OEM. To these guys, Karel said. In fact, it was originally stolen materials, and Karel originally planned to sell them to the elves cheaply, but these guys had to drill into the sleeve, and they were simply here to give money.

Hearing Karel say this, those guys were originally very happy, and signed the contract very happily, until the next day they found out that something was wrong, a magic iron, that is, 10 kilograms is worth 60,000 gold coins, and 260 kilograms is 1.56 million gold coins, which is 560,000 more than the price quoted by Karel. They scolded themselves for having a pig brain. (To be continued......)
