Mechanical alchemy room of the castle.

Renn sat at the table intently. In his hand, a metal component was creeping and deforming like a melting liquid. After countless attempts, it finally stabilized. He nodded with satisfaction, put it aside, and then picked up another piece of alloy to continue trying.

There are already hundreds of parts on the desktop.

Each part has different specifications and parameters, and the materials used are also different, including machines, springs, barrels, magazines... Many parts are also carved with runes, flowing with the light of energy.

After a moment, another part was completed.

"call……"

Renne exhaled a long breath and rubbed his forehead. After using the activated metal for a long time, it consumed a lot of energy. The more refined the structure, the more difficult it was.

This was the longest time he had studied guns. He started back from the Sain Plateau. For more than two months, he had to stay in the mechanical alchemy room for half a day almost every day, sometimes even for a whole day.

But the effort is worth it.

He finally developed a unique gun that combines a soul gun with a thermal weapon in his previous life.

Rennes originally planned to work with Blemit to study, but after the dwarf introduced the craftsmen of the Lava Fort to the canyon, he ran back and didn't have time to invite him. He asked the chief craftsman Brestine, but he couldn't explain clearly. It seemed that there was something important, which was related to archaeology.

So I had to give up, just so I could not help Bremitt always inquire about the secrets of the machine gun.

Renn grabbed the parts on the table and quickly assembled them.

Kakka...

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

If there are gun fans on Earth here, you can recognize it at a glance that the appearance of this soul gun resembles aks74u, which is also a variant of ak47. It is a very classic short-barrel assault rifle, but the folded stock is removed. The wooden handle and barrel guard are replaced with metal, and the whole body is dark. The length of the entire gun is only fifty centimeters. At first glance, it looks like a submachine gun.

The seemingly short gun body weighs 20 pounds, and is made of various magical alloys to carve runes, which can dissipate heat and stabilize.

Because there is no stock and grip, the gun can only be held with one hand.

It is definitely not possible to give it to ordinary people to use. It is difficult to control when firing, but it is just right in the hands of the Gun Wing Knight. Gun Wing Knight is an extraordinary person. The bronze body gives them outstanding power. After fusing the first main soul, their power will increase again. There is no problem with holding a soul gun alone.

Renne never thought of getting the Gun Wing Knight to equip the Rambo's Gun.

If you do this, the secret of the Rambo Gun is almost impossible to hold. There are more than 300 people and bullets cannot be supplied at all. Moreover, the Rambo Gun weighs more than 200 pounds, and the bullet box may have four or five hundred pounds. Only a level 1 gun-winged knight can pick it up, but it cannot shoot flexibly.

Even the Rambo guns of the extreme warriors were ready to be eliminated and replaced with the soul guns he had studied.

Rennes installed an arc magazine, aimed at the wall of the mechanical alchemy chamber, and pulled the trigger.

Dada dada...

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

"It's good, it's worse than the Rambo Spear, and its firing rate and range are only half. After all, it's a short-barrel gun, so it's already great to be able to do this."

Renne's satisfied self-evaluation.

In his vision, the fighting style of the Gun Wing Knight needs to be flexible and cannot be limited to being a gunman, so the soul gun is made into one hand and hold it with one hand so that the other hand can hold another long sword. When it is necessary to fight in close combat, you will never be helpless.

The magazine I just finished shooting uses conventional gunpowder bullets and has no rune effect.

Rennes activated the metal and fused the parts that did not need to move the gun body into one, and even the window of the bullet shell was completely sealed.

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

Rennes replaced it with another different magazine and fired again.

Dada, amid the violent gunshot, the runes of the soul gun lit up, and the firing rate was faster. Thirty bullets were fired in just about eight seconds, and the power of each bullet was slightly increased.

And, no shell was thrown out!

This is its biggest highlight, using shellless bullets.

Rennes devoted himself to researching for more than two months, and the most important result was the production of shellless bullets.

In my previous life, shellless bullets were born on Earth very early. The charge was made into a solid block and connected to the warhead. The striker ignites gunpowder and fires the warhead without leaving any ashes.

There are many advantages of shellless bullets. First, the bullet is light and can carry more ammunition; second, it does not need to throw the shell, which simplifies the structure of the gun and completely closes the receiver, prevents sand and dust or debris from entering the gun chamber, and extends the service life of the gun.

But shellless bullets also have a fatal disadvantage, that is, spontaneous combustion.

The heat residue generated by the shooting is in the chamber of the gun, and the new bullet may be ignited as soon as it enters. On the earth, shellless bullets have not become popular because they cannot solve the problem of spontaneous combustion, as well as the shortcomings such as waterproofing, high temperature resistance, and difficulty in storage.

Renne didn't want to create shellless bullets.

However, while studying the soul gun, he found that the launching medicine of the soul gun bullet, also known as "phlogistin", was actually a solid mixed with magic metal, which could control deformation with activated metal.

Moreover, the ignition point of phlogistin is very high, so soul power is required to be ignited through runes on the soul gun.

These two characteristics suddenly reminded Renne of shellless bullets.

After hundreds of attempts, he finally made the phlogist into a shell, and then the launching medicine contained inside the earth formed a unique shellless shell.

When firing, runes are used to stimulate the phlogist shell, creating high temperatures, ignite the internal launching medicine, generate huge thrust, and shoot out the bullet. There is only a very small amount of gas residue in the gun chamber. The next bullet enters the chamber because the pyrotin shell has a high ignition point, so it is not afraid of spontaneous combustion.

The most important thing is that the phlogistin used for shellless bullets is only one-twentieth of that of normal soul gun bullets.

The power of a general phlogistics bullet depends on the amount of soul power it has been put into.

The gunman's soul power is very limited. A first-level gunman, even if he uses the least powerful phlogistics bullet, can only fire more than a dozen shots at most, and his endurance is very bad.

In essence, the gunman is actually a spellcaster.

The soul gun is the gunman's staff and an indispensable casting medium. However, most gunmen have low soul transformation and limited qualifications, and cannot master meditation methods. They do not have the strong soul power as much as the caster, which leads to restraining their hands and feet when shooting.

This is also the main reason why the Gunners are at the bottom of the extraordinary profession.

Even if the gunman has practiced to the middle level or even higher level, his soul power has increased significantly, but the soul power required by the pyrcin bullet also increases dramatically. The stronger the gun skills, the less he dares to use them indiscriminately. The problem of combat endurance is only slightly alleviated.

Alan Ershi has never developed an automatic rifle or machine gun. It is also because of the limitation of soul power that a shuttle pyrogen bullets quickly fired out. Before the enemy died, the gunman fell down first.

The shellless bullet solves this problem very well.

The phlogiston shell no longer determines the power of the bullet, but only serves as a primer to ignite the launching medicine. This can greatly save soul power, and the number of bullets that can be activated has increased by dozens of times!

Dada dada...

Rennes fired continuously and fired more than a dozen magazines.

He only held the gun with one hand, and the gun body was as stable as Mount Tai. In fact, the recoil was not small in his hand, but it seemed to be non-existent. Hundreds of bullets were shot in a hole that was only the size of a fist. So many bullets kept firing out, the soul gun heated up slightly, and multiple ice runes dissipated heat at the same time, and a faint mist appeared.

When one thousand bullets were fired, the soul gun was still working steadily.

Renn stopped satisfied.

"That's all."

He didn't try again, and glanced at the mobile phone interface. One thousand bullets consumed three grids of power. He was a level 8 wizard, and his soul power was far higher than that of a gunman. Even wizards of the same level were beyond the reach. It was normal to consume only three grids of power.

If it were a first-level gun-winged knight, it would be impossible to shoot 300 to 400 shellless bullets.

Renn picked up a shellless bullet, which was completely different from an ordinary bullet. The shell was rectangular, wrapping the bullet head, revealing only a small tip of the bullet.

If such bullets are promoted, the combat effectiveness of gunmen around the world will increase dramatically, transforming themselves into the most popular extraordinary profession.

But it cannot be used to give it to ordinary people, and its impact on the world is much smaller than that of pure gunpowder and guns.

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

Renn learned that many well-known powerful soul guns use dimensional technology, and can load tens of thousands of bullets in one magazine. Not only does it require changing the magazine, but the bullets are also hidden in the dimensional space. Even if the magazine is lost, the bullets cannot be removed without the corresponding unlocking method.

He lacks materials and does not have corresponding knowledge, so he cannot produce them for the time being.

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

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

"It's called a submachine gun, it's simple and easy to remember, and it looks like a submachine gun, but its power is equivalent to an assault rifle."

After confirming the design and name, he immediately began to mass-made submachine guns.

The magic metal that had been prepared was brought over, and the activation metal was running with all its strength. In just two or three hours, fifty brand new submachine guns were created.

With the grasp of the metal touch, the performance and size of each submachine gun are not bad at all.

Rennes knew that the quality was fine without testing the gun.

An extreme warrior knocked out of the door, his face full of joy, and said, "Boss, the dwarfs in the canyon have notified that Fort King Kong is completed."

"So fast?"

Rennes couldn't help but be surprised. He was busy studying submachine guns and had not passed for several days.

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

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

The scene in front of me changed, and a wide hall appeared. This was originally a cave that Rennes smashed on the rock wall. After being expanded by dwarf craftsmen, it was completely different.

The teleportation array is located in the middle of the hall, with a height of more than fifteen meters above the top. The entire hall is a huge hexagon with a diameter of more than a hundred meters, and is magnificent. Each flat stone wall has a spacious passage leading to different rooms.

The chief stonemason of Lava Fort Brestine, with more than 200 dwarves, stood outside the teleportation array and waited.

"Lord!"

Brestine said in a very loud voice: "Fort King Kong has been built. Please accept it. If there is no problem, we will leave after paying."

"Okay." Ren nodded happily.
To be continued...
