Arthur was looking forward to Rambo's Tristi roaring with a six-barreled large-caliber Gatling, but Rambo was a little curious, he was still a little skeptical about the effect of Arthur's proposed design of this rotating barrel, and he couldn't imagine that Arthur might fire thousands of rounds a minute, even a dragon, under such a terrifying stormy blow.

It's unimaginable.

He realized that the future potential of the magic guide of the "gun" was likely to exceed his expectations.

Now his senior brother is really going to become a tycoon, and with such financial support, he also has a hunch that the day when Arthur will become an alchemist may not be far off.

Unbeknownst to him, his mentor had actually prepared Arthur for an exceptional promotion ceremony.

Arthur didn't choose to tell Rambo the news, because he was afraid of irritating his little friend, he knew that his little friend was harmless on the outside, but he was still very proud and sensitive inside.

Arthur left the energetic Rambo himself in the laboratory, walked into his room, and turned on the wind of silence in the room, which is a very good second-level auxiliary magic in the spell list of the Loran Mage Association, the effect is equivalent to mute, and in some rooms of the magic hut, this spell effect is solidified to provide a quiet environment for the owner.

Arthur took out his Arcane Card and checked the information left on the Arcane Card, there were many messages from strange alchemists from all over the world, and he needed to reply to them one by one, most of these were asking him for a license to make a gun, according to convention, depending on the rating of the magic guide, the cost of each license ranged from 50 to 500 Arcane Points.

And Arthur's gun, rated AA in the Alchemy Association, is the degree of innovation, power and the commercial potential of the magic guide itself are very optimistic about those alchemy masters, and the value of such a license for alchemy invention will naturally not be low, according to this rating, each license should be 200 arcane points.

In other words, each alchemist needs to pay 200 arcane points to Arthur to obtain this license to produce this alchemy product, which is not low, but the alchemists are not stupid, and this is only a drop in the bucket compared to the possible benefits from producing and selling this magic guide in the future. In just over half a month, including the time when he was not in the Loran world, his Arcane Card already had more than 500 alchemists' permission application information.

Arthur was startled at the sight of this number.

What is the concept of 500 alchemists, I am afraid that in the south of the entire continent, as far as Arthur knows, the total number of alchemists near the Principality of Roses is not 50, and 500 alchemists This is probably the whole continent is here, Arthur was shocked, from this point of view, the world shrouded by this magic net is probably far beyond what he originally thought was just the continent in front of him.

But even the total number of these five hundred was very surprising to Arthur, and, the point was that these five hundred licenses were obviously not the total, and even now, he saw with his own eyes, that number was still growing.

500 licenses, that's 100,000 arcane points, and this multiplication is simple.

One hundred thousand arcane points is equal to one hundred high-grade crystals, one thousand medium-level crystals, and ten thousand low-level crystals.

And before, just to get the thunder-based high-grade magic crystal used to build the electromagnetic gun, he used almost all of his savings and owed a lot of debt, which can be imagined, what a lot of money this is.

This wealth is truly staggering.

This was the first pot of gold he, the master alchemist Arthur, had earned in this world.

Just a small goal, Arthur thought happily.

But the pleasure didn't last long, and Arthur remembered that Mentor Victor had a huge debt, and that debt might even include a dragon, and the joy of this wealth piling up soon faded a little.

He angrily replied to the alchemists who applied for permission on the arcane card, thinking that for each reply, two hundred arcane points would come in, so his mood became happy.

…… Four-five, four-six......

Replying to letters while secretly counting.

In these letters, different alchemists have different opinions about the gun he invented, for example, one letter discusses with him whether the angular velocity of the bullet in the chamber of the gun rotates at high speed, which enhances the stability and accuracy of flight, and whether this principle can also be used in the design of other weapons, such as the arrow of arrows. Huh, this is a rocket?

In another letter, he praised the principle of the propulsion force of a firearm, arguing that the tightness of the chamber determines the power of the bullet, but also increases the need for the metallic strength of the firearm. So if this power continues to grow indefinitely, what will be the final result?

What is the result?

Arthur thought, it's Boom! Explosion, earth-shattering explosion, man, your idea is dangerous, I support you, if you continue like this, you will become the Nobel of the other world.

Others want to give certain properties to the bullets of the gun, such as giving it the attribute of light energy element, so that it has the function of destroying evil, which is obviously the idea of a certain priest of the Chenguang Church.

Others want to give it the attribute of frost energy, so that the bullets of the gun have effects such as long-range freezing and slowing. This is the same principle as the Elven Magic Arrow.

I have to say that the alchemy civilization is a civilization with a hundred flowers, and almost every alchemist has his own unique system, and many brain-opening ideas have benefited him a lot from it.

And one more letter:

"Dear Arthur's apprentice, I would say that you have really made an amazing invention. Your invention is surprising, I personally think that its importance is not in its power as a weapon, I personally am not very interested in all weapons, of course this is only a personal opinion, not universal.

What I want to say is that from your invention, we can see a new science, a knowledge that looks at our world from a whole new perspective.

This is also what I personally think is the most vivid display of your genius thinking in this invention of yours. This is related to one of my recent research topics, this topic is called Hextech Core, I don't know if you've heard of it, maybe you've heard of it, maybe you haven't, oh yes, your mentor is Victor, then you must not have heard of it.

That bastard mentor of yours will definitely not mention my name to his proud disciple.

Oh, look, the subject is far away again, and looking at my brain, I often wonder now if the gods have withdrawn their favor from me and made me a nasty old man, so let's turn the conversation back to the original place.

If I'm not mistaken, the technology used in the bullets used in your invention of a firearm is the essence of your whole invention, yes, that's it.

In addition to this, although there are many interesting things about your little things, but in a scientific sense, IMHO, it is not an innovation, and the real essence of your invention should be on the principle of the explosives of this bullet, which is about the understanding of the outstanding material properties of the world, and if you look at the world from a new perspective, you will find new powers, and that's what I want to say.

There is probably a new science hidden in the principle of this explosive that you have invented, and I hope that we can continue to extend it in this direction, and I have a hunch that we will gain a lot......"
