With a clanging sound, the first human cannon was made, and Feige placed his hand on the brass cannon and slowly injected mana into it.

The connecting lines between the runes glowed slightly, and the magic fluctuations slowly increased. The runes are attracted to each other, making the human cannon itself a tighter and tighter whole. By the time the last rune had been successfully lit, Feige knew that the human cannon was at least no problem when it came to engineering and manufacturing.

"Find a place to try!"

With the fire dwarves dragging the cannon, Feige arrives on the battlefield, which is empty enough for experiments. There was no trace of the great battle that had taken place here some time ago, and the corpses had been cleaned up, and even if there were any remaining fragments, they had either been eaten by the maggots of hell or burned by fireballs that fell from the sky. Only a faint smell of blood lingered around, but most of the time it was suppressed by the scorching smell of hell.

The parchment scroll of the Frozen Core is stuffed into a slot on one side of the cannon, and the other side is filled with a fire elemental crystal. Despite the effect of creating ice, the core of Freezing is actually fire elemental magic. Kazmuk said he couldn't understand it at all, but as long as he didn't ask, Feige wouldn't take the initiative to explain it to him.

Feige hopes that Kazmuk will speak up so that he has more hope of turning the fire dwarves into subordinates and friends, not just soul contract slaves. This guy deserves to have survived in hell for more than a hundred years, and he is very cautious and careful everywhere. However, this kind of caution and caution, the other side of it is actually obeying the powerful order of hell, losing a part of its flexibility, why not be assimilated by the influence of hell?

"You come and manipulate and feel the mana drain. You don't need to aim, just shoot a shot. Fitch stood aside with his arms crossed, handing the opportunity to fire the Freezing Spell to the dwarves of the Fire Elemental Plane. Kazmuk was a little trembling, of course, his hands could touch the lava, but he still shivered in front of the ice.

Thankfully, there was nothing wrong with Feige's spell and rune design and cannon manufacturing, and a ball of blue energy flew out of the cannon's muzzle, freezing and aggravating as it froze, flying away in a parabolic trajectory. Because the launch angle was not calculated in advance and the duration of the environmental shell was endured, the "cannonball" did not explode until it hit the ground, and it became an ice hockey ball, which also gurgled and bounced on the ground for more than ten meters.

With the sound of "popping" and cracking, a white mist burst out, and it felt like more than a dozen dry powder fire extinguishers had exploded at once, and the area with a radius of ten meters was suddenly shrouded in the power of freezing cold. This white mist continued to spread and weaken rapidly, and when it disappeared, the area of the central core was covered with a layer of ice, and the temperature could still sting the skin of the demon, and even create a large number of bleeding spots, which showed that the power was enough.

Feige used his wings to create a current, and suddenly noticed that the temperature had plummeted, and hoarfrost instantly climbed up his wings. He sank down, hurriedly throwing himself out with his apparition. It turned out that the cryogenic air mass produced by the freezing core was still there, and it sank to the ground near the explosion point. The wind on the first level of Hell was small and didn't blow the thing away, and the wind created by Feige stirred up the invisible cold, and if he hadn't seen the opportunity quickly, he might have quickly lost his lift, and then fell down and frozen.

"The power of the core area is a bit big, if I can't bear it with a desire demon, the bone demon will have no effect, and even the horn demon will be hit hard. It's not going to work, it's definitely not going to work. Feige spiraled along the perimeter of the blast point towards the core, feeling the effects of the cannon's continued power while thinking about improvements. "The human cannon is a profitable product, not to update the devil's combat power, so this cannon must first be cheap, and then it must look good, so that it can be sold more expensive. But you must not dominate the crowd, and the devils are still needed as protagonists on the battlefield. ”

"So the spell in the Freezing Core needs to be further weakened, and in order to prevent the Devil from using other spells to deal excess damage, the power amplification spell of the cannon body needs to be manipulated. The best thing is to keep it for yourself, and the devil can use it if you have it. ”

Changing the Freezing Core and Power Amplification spells does not affect how the Human Cannon is fired, so this cannon can be used to collect parabolic data. In line with the design policy of "insufficient accuracy and no manual adjustment of the ruler", Feige hastily collected the parabolic range data forty times to end the work. A very rough data sheet was calculated in the Cat Tease, and the first cannon was cleaved to pieces by Feige with the Pit Excalibur, completely destroying it and burning the Freezing Core Scroll to ashes.

Kazmuk looked at the scene with some incomprehension. This cannon can be sold for more than 100 spirit coins, so why did it be dismantled? Moreover, that Freezing Core Spell was the most magical fire elemental spell he had ever seen, and it was no problem to say that it was priceless. A fire dwarf can use fire mana to create freezing cold, which will completely change the state of the fire elemental plane in their hometown, and if the fire dwarves can master this kind of killing weapon, they will no longer have to fear the threat of fire elementals and fire djinns, and will have the power to defend themselves for the first time.

But Feige didn't hesitate to destroy the scroll.

Kazmuk didn't dare ask, but he had a feeling that he might never see the Freezing Core Spell again. Later that day, a new blueprint for the human cannon was handed to him, along with a copy of the "Freezing Core". He looked at the new handwriting on it, and although he couldn't read the spells and runes, he could still count. The new cannon uses 30% less runes, and the cost is expected to be reduced by this much - and the "Frozen Core" uses half the fewer runes.

"Engrave this freezing core directly into the cannon and remove the function of holding the scroll. On the other side, only fire elemental gems are accepted, and there is no need to make a common interface for each elemental gem - these two parts save a lot of rune costs. ”

Kazmuk could quickly understand these two improvements, but he noticed that the missing runes were not only on the sides of the cannon, but also on the cannon body. There is no change in the rotation adjustment range, and the runes belonging to the original Devil Cannon have been reduced again. He was amazed at Feige's ability to learn and modify spells, but even more surprised at the hidden mind behind Feige's actions.

A devil, instead of always thinking about enhancing the power of the weapon in his hand, is weakening it?"My lord......" Kazmuk hesitated for a moment, but decided to ask. "Is it possible to make money by weakening the power?"

"Is it weakening, why don't I know? Kazmuk, when are you going to be able to read the design?"

"My lord, I don't understand, but there are a lot fewer runes on it. ”

"What you said makes sense, there are too few runes to look advanced enough, I should add some more to it - anyway, there are no mid-level devils who use this cannon who like to study rune spells. Feige took the drawings back, and came back half an hour later with another copy. This time, there were a lot of runes on the blueprint, but how many of them were really useful? Kazmuk saw a lot of runes that represented glowing and sounding, and guessed that Feige had simply added a "special effect" when firing.

"My lord, what if...... I mean, if the camp treasury was attacked by a spell during a previous demon raid and some of the blueprints were damaged, what punishment would I have?"

"If it is damaged, it will be punished with ten lashes, and one hundred spirit coins will be deducted. ”

"What if the blueprint of the devil's cannon was found because it was used before, and it was left on the table without protection, and it was completely destroyed?" Kazmuk asked as he clenched his fists to cheer himself up.

"Then forget it, if it's gone, it's gone, everyone in the province is upset. Feige pointed at Kazmuk, "It's better to put your mind in the right place than anything else, you know?"

The fire dwarf hummed and let go of his fist. He knew he had made the right bet, and this demon named Feiqi really didn't want the devil to master stronger spell cannon skills. This "master" is not a typical devil, and his approach is different from other devils, or even the opposite, which makes the fire dwarves a little interested and hopeful: they may be about to change.

The real change came when the "first" human cannon was placed in front of Kurdan. It took the style and structure of the classic "Napoleonic cannon", with a bronze cast cannon body resting on two wheels, and two or three mid-tier devils with enough power to drag it around. Dense runes are engraved on the inside and outside of the barrel, the outer layer serves as a protective (in fact, it is an ornament), and the inner layer is used to increase the power of the spell, increase the range, and add environmental protection. The Freezing Core spell was at the bottom of the barrel, and Kazmuk added a "disassemble and destroy" trap, which was approved and praised by Feige.

"That's it? It looks so small, it's not powerful at all. Kurdan looked at the mess of runes on the cannon's body, and only felt dizzy. "But you won't be out of sight, so show me a demo!"

There are many captured demons in the Blood Dealers' Bazaar, sold as prisoners of war slaves to merchants and adventurers who have come to hell, and there is still a lot of surplus stock that can no longer be sold. Kurdan gave the order, and a group of ugly, weak, and unmanageable demons were dragged to the clearing in chains. "Just hit them," said the Deep Hell Purgatory.

"It's about four hundred meters away. Fei Qi was obviously adjusting according to the ruler table, but in fact secretly using the cat teaser stick to make more accurate calculations. "Shall I launch, or will you enjoy it for yourself?"

"Come on, I'll just watch. I don't need this little toy. ”

"Middle-level and high-level low-level devils are fine as long as they need them. Fei Qi connected his magic matrix to the human cannon, adding some power and precision out of thin air, and then injected mana.

In a dazzling flash of light and a roar full of will to fight, a blue crystal ball-like cannonball was fired, dragging a hellish crimson trail behind it—the effect of pulling the wind was not in vain the runes that Fei Qi had so painstakingly thought about wasting on the cannon.

The shell landed five meters off Feich's calculations, but it looked good enough. The effect of the explosion of the dry chemical fire extinguisher was repeated, and a thick white mist violently expanded and then slowly spread. Kurdan frowned, "Isn't that so you can't see anything?"

"As long as it doesn't affect the effect. Fei Qi pinched his nose and said, "Theoretically, we can continue to improve and create an explosion to blow away the cold." But that adds a lot of cost and doesn't make it more powerful. ”

"You don't understand, clouds are a very nasty thing on the battlefield, and it is dangerous not to see the conditions on the front line. Courdan always had to find a way to show his wisdom, and Feige understood this, so he made a qualified "Party B" and said yes again and again. Afterward, the Lust Demon and the Hellpurgatory Demon flew towards the explosion point.

More than thirty closely aligned low-level demons had completely frozen to death. The fluid in their bodies swelled outward from the freeze, so that their skin and flesh were covered with frost. As the main force of the Blood War Demon, the Babu Demon has a survival rate of forty percent, but even if he is alive, he is already frozen, and he is completely incapacitated, so he can only wait for help or wait for a mending knife.

The Eagle Demon and the Soul Eater, two flying demons that are about the same level as the Lust Demon, are placed a little farther away to simulate the effect of being close to the ground. Feige played a little crookedly, so the Vulture was closer to the Freezing Core than expected, already freezing to death and frozen. The Soul Eater is slightly better, but there are a lot of breaks on the bat-like wings, and the overall stiffness has become greater, and the ability to fly is definitely greatly reduced. Although we didn't find stronger demons to experiment with, judging by the current situation, the killing effect might be discounted, but the frozen battlefield would definitely limit their activities.

Courdan's heart was full of shock. It's seen a lot of spells more powerful than this, but it's the first time I've seen a spell item that can be fired so easily. Some mages are able to summon meteors from the sky to smash down and smash a city to the ground. But how much can a person with that kind of spell withstand in a day? The consumption of mana and the long casting time are still bearable, but how long do you have to wait to cultivate a person with that kind of casting power? How many people can there be?

Now, this cannon can be used as long as there is a mid-level devil mana, and the time to train the caster has become the time to find a craftsman to make it according to the drawings, which is a world of difference. If the mid-level devils all possess the ability of freezing spells no less than that of the ice demons, and can continue to attack at a long distance, then the balance of the bloody battle will definitely be broken.

"Did you come up with this?" asked Fitch, pointing to the fist Xiaoice frozen core in the center of the explosion.

Feige nodded, but shook his head again: "I've just made a little improvement, and the real foundation is still the devil's ......"

"Needless to say, I see!" Courdan interrupted Feige's words and hurriedly said, "The whole of Hell obeys the orders of the Devil's Grand Commander, and I am one of the most loyal of them. Don't worry, no matter how much you produce, I can sell it! This war zone, the war zone next door, and even the war zones! Next time, the demon will definitely meet and break the blood!"

Feiqi nodded vigorously, and he finally swallowed the last word "cannon" of "devil's cannon". Since Courdan thinks it's Asmodeirs' will, it's its own ingenuity, and Feige doesn't need to be a fool to wake it up, right?

The main reason for this misunderstanding is that Courdan underestimated Feige and always thought that he was not capable of completing such a design and manufacturing. The abilities of the demons in hell are basically fixed, and they have even become rigid, and the "stereotype" has become ingrained and become a mistake.

"I think this cannon is suitable, and it can even be said to be perfect!" Kuldan never skimps on words in praising the Great Demon King, "In order to commemorate the birth of this meaningful weapon, to show its power, and to remind everyone to carry out the will of the Devil King, it is better to name it the Demon Piercing Light Killing Cannon!" I will give you 666 spirit coins for a cannon, what do you think?"

"Is that good? Until production is fully expanded and costs are reduced, you can already give me 600 spirit coins. Wouldn't 666 make more sense when you go for takeout?"

"Then I'm just upside down and it's 66 spirit coins?

"No, your tasks and roles are important, very important! If it weren't for the fact that the cost is really high, I'd like to give you a little more profit. But ......"

"Don't say it, it's disgusting like an angel to push it down. We're the devil, so let's just do it! Hurry up and produce, I'll test fire a few shots here. I'm happy now, you know!

I don't know if you're really happy, but you can't imagine my happiness anyway - Feige tried to suppress his heartbeat and hurried away before he was laughing. A cannon with a manufacturing cost of 66 spirit coins sells for 600? Fei Qi is only thinking about working as soon as possible now, who will delay making money!
