Magic Ballista and Magic Cannon are two different firing devices, and the firing tube of the Magic Ballista is mainly used to add attributes to the Magic Ballista and provide initial power. The magic bolt itself increases speed, adjusts direction, and strikes with precision. The magic cannon has to preset the coordinates, lock it and fire the projectile, and the power is all provided by the magic cannon.

The projectiles fired by the magic cannon can only be easily corrected to the lower trajectory.

Finally, there is the primitive magic cannon, which is no longer built on the Xia River side, and it is an elemental ball that is fired, which is huge, but the consumption is also large, the cost is high, and it is not cost-effective to put it on the battleship, and it is even more serious if it is placed on the flying device.

The magic cannon that fires the elemental orb is okay to install in the stronghold. But the empire has fortress cannons, and expensive magic cannons are a bit embarrassing.

Xia He asked the magicians to develop magic crossbow arrows, with a range of more than one hundred and eighty miles, and a speed that exceeds that of most magic.

As for the power, it is also quite impressive, at least much more powerful than the huge weapons that Xia He has seen in the technological world. After the magic crossbow bolt is completed, the weapon on the flying equipment can be regarded as a supreme power strike.

The disadvantage of this weapon is that the cost is still higher than that of magic artillery.

With the same power, in addition to the original magic cannon, the magic crossbow bolt is the most expensive, followed by the magic cannon, and the fortress cannon is the cheapest.

Mainly in the magic crossbow arrows, the portrayal and refining of some magic arrays require special materials. The cost is all in the material, and the difficulty in manufacturing is not high. There is a high-end alchemy factory. Now Xia He is not short of materials, and the Starry Sky Worm provides a large amount of materials, as long as he does not plan to conquer the universe, he only tosses in this world, which is enough for the time being.

In another laboratory, a group of young mages also shouted excitedly.

"Success!

Above the magic circle, a rectangular metal box floated. The width is less than one meter, silver-gray, the upper part is densely covered with magic patterns, and the magic pattern on the bottom surface is hollow, and the center is blank.

This is the task assigned by Xia He, the reel sequence launcher, which requires it to be able to be mounted on the aircraft.

This reel sequence launcher can only fire dragon scale scrolls, and the volume is easy to control. The trouble is the launch method, Xia He's request is to use teleportation to activate the dragon scale scroll to a predetermined location. For example, the caster of a magician is made to be the size of a ring or bracelet, and naturally it cannot be expanded to such a function.

The magicians' solution is to prepare for magic.

The dragon scale scroll is delivered in the original way in the dispenser, and at a distance of 500 meters from the target, it will activate a pre-released magic to read, and then a 500-meter teleportation spell will activate the scroll after sending it to a precise location.

This thing doesn't shoot far in a flat shot, but it can attack from a height of 10,000 meters. The dragon scale scroll can be dropped at an angle, and the self-control ability is extremely strong.

"It's a pity that you can only fire the dragon scale scroll. The magician in charge of the project sighed at the finished product.

"That's what the Duke asked, let's do it, and the Lord will definitely be satisfied. ”

"Yes, teacher. Look, this thing is a work of art!"

The magicians gossiped and didn't care at all about the shortcomings of the teacher. What's wrong with the dragon scale scrolls, there are a lot of dragon scale scrolls in the duke, mainly the artificial dragon scale production is okay. Looking at the meaning of the duke, there is no need to make other scrolls in the future, and all of them are produced in the form of dragon scale scrolls.

Of course, Xia He didn't care about this kind of restriction, because the scrolls thrown down from the flying machine would definitely not be low-level.

At least epic-level scrolls are required to be worth supporting. From a height of tens of thousands of meters, release a master-level magic, is there a must?

Xia He's five-person team was designed to be able to deal with level 20 professionals.

When air support is needed, epic magic is the bottom line.

If you want to create a legendary level, it is not easy to create a dragon scale scroll, but it is only a matter of increasing the cost of creating an epic level.

In the future, the cost of flying battleships and hexagram airships will increase, improve survivability, and provide stronger strikes than before. The last time I went to sea, the flying equipment had a good effect on the demon battleship. However, these demon warships on the sea are also patchwork cannon fodder.

Xia He found a lot of information in the starry sky battleship of the demon clan, and knew that the demon clan had better warships.

There is no way to update his weapons. This is the enemy forcing you to improve, otherwise the next time you encounter it, it will not be so easy to deal with the demon warship. The final result is that if you want to solve the demons, you have to stick to hand-to-hand combat.

Xia He has always advocated crippling the enemy and then going to hand-to-hand combat.

Otherwise, the magician's hand-to-hand combat ability is just as good, so why lose the magic first in the fight?

Each laboratory is completing the tasks assigned by Xia He step by step, and these drawings have to be finalized in the end, and Freya has to make a decision. But as long as the completion is reached, these mages will be rewarded.

The magicians don't care about the reward for a long time, and this mission has made everyone gain a lot.

Freya has collected a large number of drawings, and I feel that these magicians, Xia He's expectations are still reasonable. Every task is completed, and no matter how it is completed, it is absolutely achievable. All the objectives set by Xia He were solved, and the level did not limit the imagination of these magicians.

"Austin, come out and do something!" Freya said loudly.

The goblin towering crawled into the room, prostrate at Freya's feet. Freya kicked it over, and the goblin dodged nimbly, but there was a thud in her chest.

Freya said proudly, "Can you get out of the way?"

"Can't hide. Austin said with a smile.

"You're still so happy, I'm still kicking lightly?"

"No, no, no, there's something to do, I'm happy. ”

"All the drawings, you summarize it, what the adults want, complete it as soon as possible, this has already dragged on the schedule, and we will go on the expedition next month, at least some of them must be produced first, and some of the troops will be redressed. ”

"Yes, yes, I'll do it. ”

Austin smiled. The alchemy factory in Sun City does have production capacity, but after Austin finally finalized these equipment, it was not the kind designed by the magicians, and all of them had to be integrated and optimized, so there was a value in secrecy.

Some key parts, such as a puzzle lock, have the ability to self-destruct, and are fully enclosed, artificially creating magic black boxes.

You can only use it, but you don't understand what's inside.

Critical parts, not repairable, can only be replaced.

These parts can be made by other people, but if you don't know the design, the cost will be very high. There are many things that magicians can produce if they don't put in the effort, but they don't mean much.

On the Cape of Storm, the four seasons are not as distinct as Rhode Island.

It's already snowing in Rhode Island, and it's a little cold in the south. In the area close to the mainland, there is thin ice on the sea, there is no freezing in the east, and the port is still operating normally. Not so in the north, where mining work was temporarily suspended. However, the Xia River side is well coordinated, and the coal mines on the seabed are mainly mined in summer.

In winter, manpower is concentrated on processing and making raw coal crystals.

After treatment, the raw coal crystals are of high quality and inexpensive, and the storage energy is not as good as the magic rough stones, but from the price considerations, the raw coal crystals are more cost-effective.

All the equipment in Xiahe is mainly crystallized with raw coal, and only the magic rough stones are used for advanced purposes. As for the direct use of raw coal, it only preserves this ability to avoid that sometimes the energy is not processed and the equipment at hand becomes a pile of garbage.

Long trains run from the north to the south, along the tracks on the east bank. This train has more than 40 carriages, filled with raw coal crystals. Escorting the carriages were two field squadrons, plus a ten-man mage regiment.

When the train circled to the northeast corner of Rhode Island, it passed through a forest, and suddenly a magic alarm sounded in front of it, and the train was driven by two intelligent mechanical beings, and immediately took emergency braking.

The train taxied for more than a hundred meters and stopped, and immediately a soldier went down to check, and on the track in front of it, there was a demonic beast, more than four meters long, similar in appearance to a crocodile.

This demonic beast has been transformed, its scales have increased, and its body exudes a faint demonic aura.

Check the soldier changes color, which is contaminated by monsters!

Rhode Island, how could such a thing happen!

"Go back!" The armored soldiers didn't attack the monster, they immediately retreated, he didn't know what was happening, but the training content made it very clear, if you encounter something unknown, if you can't judge the degree of danger, you will immediately defend and pass the information back to Sun City.

The accurate shooter immediately retreated, all three men followed him, and the armor slowly retreated.

The beast lay on its stomach on the railroad tracks, not looking back.

The five soldiers returned to the car and reported the matter to the mage regiment. The mage group was also taken aback, and immediately activated the emergency magic array on the train to contact Sun City, explaining that there was something about the demonic beast being polluted by demonic qi and having been demonized.

Sun City replied almost within ten seconds, asking them to deal with the monster first, as close to the direction of Sun City as possible. Sun City will send flying battleships and six-pointed star airships, plus magic airships to transport troops, and directly come to support.

On the train, the mechanical soldiers were awakened, and a whole squadron came down from the train and came to the front, not far from the monster.

The five magicians of the spellcaster team judged the level of the monster from a distance, and finally decided to attack.

The monster should only be level 20, after the demonization, the attack power increases, the defense power decreases, and the speed becomes faster, but it loses its wisdom or instinct.

"Are you ready?" said the leader of the spellcaster's team, contacting the intelligent mechanical beings on the train.

The intelligent mechanical life has installed the weapons on the front of the car, a small magic cannon, plus a new long-range magic musket. Flying robots were also released, ten in all, two hovering above the train, and the other eight were flying into the distance for remote vigilance.

"Let's do it. The leader of the spellcaster team, with a solemn expression, gave the order to attack.
