On a hidden forest road, three specially reinforced electric carriages were moving smoothly and quickly.

Due to limited construction capacity, the road is less than 10 meters wide, but the road surface is entirely made of tempered yellow clay.

The road surface structure is designed to drain water, prevent skidding, and prevent thermal expansion and contraction, and strict restrictions are placed on the road slope, which will never exceed 5 degrees.

In addition, roads are only one form of transportation in the mountains.

Alonso and his apprentices have already begun demonstrating the feasibility of mountain trams.

Rosen was sitting in the second carriage, carefully experiencing the riding experience of the electric carriage, and then drawing conclusions.

"It is faster than a horse-drawn carriage, so the noise is louder than a horse-drawn carriage, and the up and down bumps and turning tilts are much more serious than those of a horse-drawn carriage."

"The wheels are very noisy and have poor anti-skid capabilities, making them unsuitable for high-speed driving."

It has a lot of shortcomings and is far less comfortable than his previous carriage, but it is really powerful.

When I opened it sharply, I felt a noticeable push on my back.

"With more iterations, we should be able to create an electric rune tank, which can be used for sieges on plains in the future."

Just as I was thinking about it, there came another strong push on my back.

Rosen immediately said, "Alia, drive slower, aren't you feeling uncomfortable?"

Alia shook her head excitedly. "Is it bumpy? This is much more stable than riding a horse, and it's faster, and there's no strong wind in my face."

Well, since she likes it, Rosen lets her enjoy it.

The car drove along the winding mountain road for about ten minutes and arrived at a secret valley among the mountains.

"Woo~~~~"

The electric carriage slowed to a stop in front of a nondescript high wall of tempered clay.

There was a large iron gate on the high wall. The gate was already open and the guards beside the gate were saluting the convoy.

The convoy slowly drove into the iron gate.

Behind the door is a very spacious natural fan-shaped valley, and at the end of the valley is the blue sea.

This is the secret testing ground for the island’s flame weapons.

Three cars stopped in an open space at the edge of the venue.

Alia got off the car first, and after confirming with other guards that there was no problem around, she protected Rosen out of the car.

Rosen looked directly at the weapons test bench in front of him.

There was a row of tempered clay platforms, on which were fixed hollow round metal tubes.

This is the Flame and Thunder Artifact created by Master Goss, which is also the cannon from another world! Master Goss and his second son, Master Alshut, are already here.

In addition, there are more than fifty young wizard apprentices following them as assistants.

Seeing Rosen arrive, Master Goss came forward with high spirits.

"Lord, this is the first batch of flaming and thunder magic weapons we created."

"Hmm~ I think it's better to call it artillery as the lord said."

Especially the pronunciation of "炮". Although there is no corresponding word in the common language, it vividly describes the huge movement when the magic weapon is unleashed. It is also easy to read and very refreshing.

"Lord, you see, the barrels of these cannons are made of pure steel, using precision molds and Transfiguration to precisely deform them."

"The barrel is nine centimeters in diameter, and each shot is loaded with about three kilograms of explosives, which can eventually send this heavy iron ball 1.5 kilometers away."

"Here~ This is thunder medicine, its full name is Order Thunder Medicine, we call it yellow powder."

"It was developed by Master Bell. Although its power is less than the 'Soil of Fire' that Aaron discovered recently, it is far more stable and safer than the Soil of Fire."

He showed Rosen the Order Thunder Potion.

This is a yellowish-brown fine powder with a slightly fragrant aroma. Due to the needs of moisture-proof and anti-caking, it is specially made into small, smooth round particles.

At first glance, it doesn't seem to be anything special, and no one would even take a second look at it when it was thrown on the ground.

Rosen certainly knew about the existence of Order Thunder Drug. In fact, he knew the details of all the important new achievements in the territory.

But he has been very busy recently, so this was the first time he saw the real appearance of this thing.

"Master, can you show me its stability?"

Master Goss put a pinch of powder on the ground, took a hammer and smashed it down hard.

"Bang~~"

A small dent was smashed into the tempered yellow clay ground, and the order thunder charge was scattered everywhere, but there was no abnormal movement.

Immediately afterwards, Master Goss released a three-ring Breath of Flame at the powder from a distance.

After the high-temperature flames dissipate, the powder remains intact, and its flame retardancy is almost the same as that of soil.

Rosen was amazed. "It is indeed stable. I heard that only a special excitation spell can ignite it. Master, can you open my eyes?"

Goss immediately did as he was told. He pointed at the Order Potion from five or six meters away. He didn't see anything unusual, but the powder he brought with him suddenly started to burn violently.

The intensity and brightness of the burning are much stronger than the black powder in the previous life, but not as strong as TNT.

"Pah pah pah~~"

Rosen clapped his hands softly and praised sincerely: "What a good thunder medicine!"

He knew that the spell that activated the Order Thunder Potion was essentially a constant decryption spell.

During specific use, the activation spell can be adjusted at any time according to safety needs.

In other words, the order thunder invented by Bell is not only safe and stable, but also can prevent enemy spies, especially mage spies, from using magic to remotely destroy their own ammunition depots.

In the world of magic, this is especially important.

If we simply copy the knowledge and experience from Earth without making any local adaptations, at best we will not be able to adapt to the local environment, and at worst we will end up dead.

After demonstrating the explosives, Goss began to demonstrate the artillery shells.

"This is a solid iron ball, weighing about 3 kilograms. Once activated, it can fly several miles away in a few seconds. Its power is more than ten times that of a master-level throwing technique."

According to this calculation, even if Rosen used ten rings of magic power to activate the fourth ring of throwing skills, the power of the iron ball finally thrown out would be far less than this shot.

In other words, even the most common and primitive small-caliber solid bullet artillery can still drive away all the monsters and demons when it arrives in another world.

The cannon roared, and all the gods and demons ascended to heaven! But Rosen certainly thought it was not powerful enough.

"Is there a way to make the launching iron ball hollow and load the order thunder inside?"

"Because I heard that Aaron's projectiles can be loaded with flaming soil, so the attack power is particularly strong."

Alshut on the side immediately shook his head: "No, it can't be installed."

"Order mines are too stable, so triggering them will be a problem. Also, although Aaron's projectiles are installed, I heard they haven't solved the problem of barrel explosion yet."

"Of course, putting magic potions in the projectiles can indeed greatly enhance the power of the attack, so we have been trying to find a solution to the problem of remote activation of the Order Thunder Potion."

Rosen nodded to show that he understood, and then asked, "Have you ever thought about making the shells into the shape of a pointed top?"

Alshut was stunned, a little confused: "Why is it made into such a complicated pointed gyroscope? A round ball can ensure the sealing of the barrel, right?"

Goss's expression changed and he asked, "Lord, do you want to aim the tip at the target so that you can penetrate the enemy's warship more sharply?"

Rosen nodded. "I've considered that. I also think that the sharp tip has a stronger impact force. If I put a nail behind the tip, it might be able to trigger the order thunder charge."

Alshut frowned after hearing this: "Perhaps it can be made into an arrow tip. No, it won't work. The shape is too complicated and it will be difficult to seal the barrel."

Rosen smiled and said, "That's why I said the pointed top looks like this. The tail of the round top is just enough to ensure the tightness."

Alshut's eyes lit up. "Yes. But that's not right. If that's the case, the shell may roll after it flies out of the barrel, and the tip may not be pointed at the target."

Before he finished speaking, he heard his father mutter, "No, it may not roll over. This spinning top is very special. As long as it starts spinning, it may not roll over!"

At this point, Rosen knew his hint had worked.

With this beginning, the two artillery experts will naturally follow the path ahead.

You have to eat one bite at a time and walk one step at a time. After all, Rosen is not the one who actually does the work, and he cannot do everything by himself.

He no longer wanted to nitpick and dampen their enthusiasm, and said, "Then let's demonstrate its power now."

Master Goss immediately waved to several apprentices.

The latter skillfully loaded the gunpowder, loaded the chamber, then hid behind a thick earthen bunker and used an activation spell to ignite the order thunder powder in the barrel from a distance.

"Boom~Boom~Boom~" There was a loud noise and a row of artillery fire exploded one after another.

The cannon body shook, a flash of fire appeared at the muzzle, and thick blue smoke spurted out. After a few seconds, more than a dozen tall water columns rose from the sea several miles away.

Rosen used a telescope to observe the sea surface, estimated the distance in his mind, and nodded with satisfaction.

"The performance is stable, the range is pretty good, and the power is also OK. If it can successfully hit the enemy warship, it should be able to cause considerable damage."

From an artillery perspective alone, this thing is already usable.

"But there is still a lot of potential for improvement. For example, the range should be as long as possible, the caliber should be as large as possible, and the rate of fire should be as fast as possible while being accurate."

Goss took notes and wrote them down one by one.

"Lord, these can all be improved one by one. The idea of ​​the pointed top you just mentioned is also very good, but it requires more manpower and material support."

Rosen smiled and said, "That's no problem. I will invest an additional 50,000 Oggs in your laboratory."

Goss immediately said, "That's fine with me, but my son Cavendish."

"Of course I won't forget Master Cavendish. I gave him an additional 30,000 yuan, which is enough to start the initial research."

After conquering the queen, he has become very rich recently.

Goss immediately became very motivated: "Just wait, Lord. I will definitely build a cannon that will shock you!"

Rosen laughed: "Then I'm looking forward to it now."

Now we have usable artillery, but the battleships are still not very powerful.

Although the shipbuilding skills of Master Belit have improved rapidly, the size of warships is greatly limited due to the strength of materials.

So, after leaving the weapons testing ground, Rosen immediately went to find his best potion master, Wei Ge.

He wanted a better Iron Potion now.

After hearing the request, Wei Ge tilted her head and thought for a moment, then said, "Lord, I have been thinking about this issue recently, and I have a very wonderful idea."

"The initial test has been successful, but due to the limitations of the theory of magic, it is difficult to move forward."

As she spoke, a potion bottle flew into her hands, and the bottle was filled with dark blue powder.

"I call it 'Frost Dust'."

At this point, she chuckled and asked, "Lord, have you guessed what I'm thinking?"
