The castle's mechanical alchemy chamber.

Wren sat intently at the table, in his hand, a metal component was like a molten liquid constantly wriggling and deforming, after many attempts, finally stabilized, nodded with satisfaction, put it aside, and then picked up another piece of alloy to continue trying.

On the table, there are already hundreds of parts there.

Each part has different specifications and parameters, and the materials used are also different, such as brackets, springs, barrels, magazines, ...... Many of the parts are also carved with runes, flowing with a glow of energy.

Moments later, another part was completed.

"Hoo ......"

Wren exhaled a long breath and rubbed his forehead, the consumption of activated metal on the mind after a long time is still not small, and the finer the structure, the more difficult it is.

This was the longest time he had studied firearms, starting from his return from the Saine Plateau, for more than two months, almost every day he would soak in the mechanical alchemy room for half a day, sometimes even a whole day.

But the effort is worth it.

He has finally researched a unique firearm that combines a soul gun with a thermal weapon from his previous life.

Wren had planned to work with Bremet on the research, but after the dwarves introduced the craftsmen of the Lava Fortress to the canyon, he ran back without having time to invite them. When I asked the chief craftsman Brestein, he couldn't tell him clearly, as if there was something important related to archaeology.

So I had to do it, just because Bremet was always inquiring into the secrets of the machine gun.

Wren grabbed the parts on the table and quickly put them together.

Click......

A few minutes later, a complete soul gun was assembled.

If there are gun fans on the planet here, you can recognize it at a glance, the shape of this soul gun looks like AKS74U, that is, it is also a variant of AK47, a very classic short-barreled assault rifle, but the folded butt is removed, the wooden grip and barrel handguard have been replaced with metal, the whole body is dark, and the length of the whole gun is only fifty centimeters, which looks like a submachine gun at first glance.

The body of the gun, which does not seem to be long, weighs twenty pounds, and is made of a variety of magic alloys to depict runes and play a role in heat dissipation and stability.

Because there is no butt and handle, this gun can only be held with one hand.

It is definitely not good to give it to ordinary people, it is difficult to control when shooting, but it is just right in the hands of the gun-winged knight. The Spear Wing Knight is a transcendent being, and the bronze body gives them a lot of strength, and after fusing the first main soul, the strength increases again, and there is no problem with holding the soul gun alone.

Wren never thought of equipping the Spearwing Knight with Rambo's Spear.

If this is done, it is almost impossible to keep the secret of Rambo's gun, more than three hundred, and the bullets cannot be supplied at all, and the weight of Rambo's gun is more than two hundred pounds, plus the magazine box may be four or five hundred pounds, only a first-class spear winged knight can pick it up, but it can't shoot flexibly.

Even the Rambo guns of the extreme warriors, he is ready to eliminate them and replace them with the soul guns he has studied.

Wren loaded the arc magazine, aimed it at the wall of the mechanical alchemy room, and pulled the trigger.

Da Da Da ......

A rapid burst of gunfire rang out, and in less than ten seconds, the magazine of thirty rounds was emptied.

"The power is good, it's worse than Rambo's gun, and the rate of fire and range are only half of it, after all, it's a short-barreled gun, and it's good to be able to do this. ”

Wren's satisfied self-evaluation.

In his vision, the Spear Wing Knight's combat style needs to be flexible and not limited to being a gunner, so he made the soul gun to be held with one hand, so that the other hand can hold another long sword, and when it comes to melee combat, it will never be helpless.

The magazine that was just finished was a regular gunpowder bullet and did not trigger the rune effect.

Wren activated the activated metal, fusing the parts of the gun body that did not need to move into one, and even the window of the cartridge casing was completely sealed.

Suddenly, the runes on the soul spear were excited, and a chill emanated.

Wren switched to a different magazine and fired again.

Da Da, in a fierce gunshot, the runes of the soul gun lit up, and the rate of fire was faster, and it only took about eight seconds to shoot out thirty bullets, and the power of each bullet increased slightly.

And, no shells were thrown!

This is its biggest highlight, using a caseless projectile.

Wren devoted himself to research for more than two months, and the most important result was the creation of a caseless bomb.

In the previous life on Earth, the caseless bomb was born very early, the charge was made into a solid block, connected to the warhead, and the firing pin ignited the gunpowder to launch the warhead, leaving no ashes.

There are many advantages of caseless bullets, one is that the bullet is light and can carry more ammunition, and the other is that there is no need to throw the shell, which simplifies the structure of the firearm, can completely close the receiver, prevent dust or debris from entering the gun chamber, and prolong the service life of the firearm.

But caseless shells also have a fatal drawback, that is, spontaneous combustion.

The heat from the shot remains in the chamber of the gun, and as soon as a new bullet enters, it may be ignited. On Earth, shellless shells have not become widespread precisely because they cannot solve the problem of spontaneous combustion, as well as the shortcomings of waterproof, high temperature resistance, and difficult storage.

Wren didn't want to make a caseless bomb in the first place.

However, in the process of researching the soul gun, he discovered that the propellant of the soul gun's bullet, also known as "phlogiston", turned out to be a solid mixed with magical metal, which can control deformation with activated metal.

Moreover, the ignition point of phlogiston is very high, so it requires soul power to ignite through the runes on the soul gun.

These two characteristics immediately made Wren think of a caseless bullet.

After hundreds of attempts, he finally made phlogiston into a shell, which was then loaded with a projectile from Earth, creating a unique caseless projectile.

When the gun is fired, the phlogiston shell is excited with runes, creating a high temperature, igniting the propellant inside, generating a huge thrust and shooting out the warhead, leaving only a small amount of gas in the chamber. The next bullet goes into the chamber, because the phlogiston cartridge case has a high ignition point, and it is not afraid of spontaneous combustion.

The most important thing is that the phlogiston used by the caseless bullet is only one-twentieth of the bullet of a normal soul gun.

The power of a normal phlogiston bullet depends on the amount of soul power invested.

And the gunner's soul power is very limited, and the first-level gunner, even if he uses the least powerful phlogiston bullet, can only fire a dozen shots at most before it is discharged, and the staying power is very bad.

Essentially, the Gunslinger is also a spellcaster.

The soul gun is the gunner's staff, an indispensable medium for spell casting, but the vast majority of gunners have a low degree of soul transformation, limited qualifications, cannot master the meditation method, and do not have the strong soul power of the spellcaster, resulting in a restraint when firing a gun.

This is also the main reason why the Gunslinger is at the bottom of the supernatural class.

Even if the gunner's cultivation reaches the middle level, or even the high level, the soul power has increased significantly, but the soul power required for phlogistin bullets has also skyrocketed, and the more powerful the gun skills, the more they dare not use them indiscriminately, and the problem of combat endurance has only been slightly alleviated.

Alenus has never developed an automatic rifle or machine gun, and it is also because of the limitation of soul power, a shuttle of phlogiston bullets can be fired out quickly, and the enemy is not dead, and the gunner himself falls first.

And the caseless bullet solves this problem very well.

The phlogistin shell no longer determines the power of the bullet, but only serves as an introduction to ignite the propellant, which can greatly save soul power, and the number of bullets that can be excited has increased dozens of times!

Da Da Da ......

Wren fired continuously, draining a dozen magazines.

He only used one hand-held gun, the body of which was as steady as Mount Tai, but the recoil was not small in his hand, but it was as if it did not exist, and hundreds of bullets were in a hole the size of a fist. With so many bullets constantly firing out, the soul gun heated up slightly, and multiple ice runes dissipated heat at the same time, emitting a faint mist.

When a thousand rounds were fired, the Soul Gun was still working steadily.

Wren stopped satisfied.

"That's it. ”

He didn't try again, and glanced at the interface of his phone, where a thousand rounds of ammunition consumed three bars of power. He is an eighth-level wizard, and his soul power is much higher than that of a gunman, even a wizard of the same level is beyond his reach, and it is normal to consume only three bars of power.

If you change to a first-class spear wing knight, you should only be able to shoot 300 to 400 rounds of shellless bullets.

Wren picked up a caseless bullet, which was very different in shape from a normal bullet, with a rectangular case that wrapped around the warhead and exposed only a small tip.

If such bullets are popularized, the combat effectiveness of gunners around the world will skyrocket, and they may become the most sought-after extraordinary professions.

But it can't be used for ordinary people, and its impact on the world is much less than that of pure gunpowder firearms.

"It's better to be cautious and not spread it for the time being. ”

Wren learned that many well-known powerful soul guns use dimensional technology, a magazine can be loaded with tens of thousands of bullets, not only does there be no need to change magazines, but the bullets are hidden in dimensional space, even if the magazine is lost, without the corresponding unlocking method, the bullets cannot be retrieved.

He now lacks materials and knowledge to make them for the time being.

When you master the dimensional magazine in the future, you don't have to worry about bullets leaking.

Putting down the soul gun, Wren decided to give it a name.

"It's called a submachine gun, it's easy to remember, and it looks like a submachine gun, but it's just as powerful as an assault rifle. ”

Having decided on the design and name, he immediately began to mass-produce submachine guns.

The magic metal that had been prepared for a long time was brought over, and the activated metal was running at full capacity, and in only two or three hours, fifty brand-new submachine guns were built.

With the metallic touch in hand, each submachine gun is no worse in performance and size.

Wren didn't have to test the gun to know that the quality was fine.

An ultramariner knocked on the door and came out, his face full of joy, and said, "Boss, the dwarves on the other side of the canyon have informed you that Kongo Fort is finished." ”

"So fast?"

Wren couldn't help but be surprised, he was busy working on the submachine gun, and it had not been a few days.

After careful calculation, it has been less than 70 days since the start of construction, which is a full 20 days shorter than the three-month construction period agreed in the contract.

Wren put away all his submachine guns and stepped into the teleportation array.

The vision changed, and a wide hall appeared, which was originally a cave that Wren had smashed into the rock wall, but after the expansion of the dwarven craftsmen, it was completely different.

The teleportation array is located in the middle of the hall, with a ceiling height of more than fifteen meters, and the entire hall is a huge hexagonal, with a diameter of more than a hundred meters, magnificent and atmospheric, and there is a wide passage on each flat stone wall that leads to different rooms.

The chief stonemason of the Lava Castle, Brestein, with more than two hundred dwarves, stood outside the teleportation array and waited.

"Your Lord!"

Brestein said in a very loud voice: "The King Kong Fort has been built, please accept it, if it is all right, we will leave after paying." ”

"Good. Wren nodded happily.

The alchemy room, the armory, the prayer and meditation room, the mechanical workshop, and the warehouse, these five areas surround the teleportation hall, which he designed himself, and there is no need to check it again.

Of the six passages in the teleportation hall, the largest leads to the canyon.

Wren walked through the passage with a width and height of more than eight meters, the walls were equipped with crystal lamps, the light was very bright, and after a hundred meters, he officially entered the fortress.

The entire fortress is made of diamond rock, built against the mountain, covering the passage into the teleportation hall. The fortress has three floors, each with an area of tens of thousands of square meters, a canteen, a martial arts training ground, a dormitory, and all kinds of functions should be complete.

Walking out of the fortress, outside the main gate is a wide open space, surrounded by a tall half-arc wall.

Three entrances and exits were opened on the city wall more than ten meters high.

From the left is a huge shooting range, the farthest target is a kilometer away, reaching the end of the canyon, the building of the shooting range is arranged with a soundproof magic circle, and the sound of gunfire inside will not be heard again.

The exit on the right leads to a large playground large enough to accommodate thousands of people to train together, and on the side of the playground at the foot of the canyon wall rock, a long stable has been built, which currently only holds 2,000 bronze galloping horses, and will need to be expanded later.

The rock face above the canyon has also excavated dozens of sprawling caverns that allow the fire dragon to inhabit them.

There are also several watchtowers hidden high above.

All the buildings are made of diamond stone, which is sturdy and beautiful, and all show the craftsmanship of the dwarves.

Wren couldn't have been more satisfied.

It only took seventy days for the things I drew on the blueprints to become real objects, which not only exceeded my expectations, but also completed them with a high degree of speed, fast and good, and no one could do it better than the dwarves.

"Lord, how's that?" Brestein asked confidently.

"Very good!" Wren exclaimed heartily, "I am very satisfied that the dwarves are indeed the best master builders in the world." ”

Hearing this compliment, all the dwarves had pride on their faces.

Wren happily paid his other half of his wages and wanted to invite the dwarves to the feast, but he refused. It's been more than two months since the dwarves left Lava Keep, and most of them have families and are very homesick, and Wren can only say goodbye with regret.

"Master Brestein, I look forward to the opportunity to cooperate in the future. Standing on the edge of the teleportation array, Wren said sincerely.

"Then I'll wait for your news. The strong dwarf squeezed out a rare smile, "Welcome Lord to the Lava Citadel at any time." ”

With that, he entered the portal.

After Wren closed the portal, he immediately cut off the coordinate connection with the dwarven teleportation array, and then walked out of the fortress and stood on top of the city wall under the eyes of the ultramarines.

Ten minutes later, a large group of bronze galloping horses stepped into the air.

More than 300 majestic bronze galloping horses, shining with blue and gold, climbed over the rock wall above the canyon, swooped down, and ran happily on the playground, the ground shook, the air rushed, and the scene was spectacular.

Wren turned back to the teleportation hall and ordered: "Brothers, bring all the things prepared in the castle, as well as the spear-winged knights, inform them to gather, open the portal in an hour, and the real training will begin." ”
