Chapter 549

Seeing the dangerous glow in the muzzle of the magic cannon, Dean Carmen was visibly distracted.

Chen Daolin didn't pay attention to the dean, who was in a stupor, but carefully turned off the tidal magic engine, stopped the energy infusion, and the light on the magic cannon gradually faded and dissipated.

Immediately, Chen Daolin took out a fist-sized crystal stone from under the base of the magic guide cannon.

"Colored stones?" Carmen's eyes lit up again.

"Yes, it's the multicolored stone. ”

Carmen's expression was visibly surprised: "Where did you get this thing from?

Chen Daolin shrugged his shoulders and did not answer.

Shall I tell you that I dug this thing out of the wall outside that small space world on the Great Snow Mountain?

"Basically, this multicolored stone is only used for temporary energy storage. Chen Daolin pointed to the magic guide cannon: "This cannon is only used to show you, otherwise, it will be full of energy but will not be fired, for fear that it will cause an explosion." So I got a multicolored stone underneath, and if it wasn't fired, the energy would be stored in the multicolored stone. After a pause, Chen Daolin continued to explain: "But if it is in a real combat state, the multicolored stone is not a necessary thing, and there is no need for a transit energy reserve container, after charging, the magic guide cannon can be launched directly." ”

Carmen nodded, "You mean, if it's to push this magic cannon onto the battlefield......"

"You can launch it directly. Chen Daolin smiled and smiled very proudly: "I have calculated, this tidal magic engine I made, under normal circumstances, a unit can be connected to twenty magic cannons." ”

"Twenty ......" Carmen was shocked by the number.

It's not that there are no magic cannons in the magic academy. However, in the real room of the Academy of Magic, after years of research, there is a problem that cannot be overcome so far, which is the charging of the magic cannon.

You can't let every magic cannon be pushed onto the battlefield with a half-ton magic crystal, right?

Half-ton external batteries? That's just a joke. Do you keep it for someone to shoot on?

"Do you have so many magic cannons?" Carmen thought for a moment, "Your tidal magic engine is very good, and the idea of the magic cannon is also very good...... If you don't have enough here, there are still a few experimental magic cannons in the academy's real room, huh...... Two units were split in previous years, and they can also be assembled. ”

"Not for now. Chen Daolin smiled: "It's just a magic cannon...... I can get it myself. ”

Carmen stared at Chen Daolin, didn't say a word for a long time, and then nodded slowly: "If you have this kind of sharp weapon, you will have a lot more confidence in dealing with the orcs by holding the Northwest Fortress." Darling Chan ...... Where did you get this magic cannon, and how many do you have?"

"Uh...... Anyway, it's definitely enough. Chen Daolin smiled.

Can I sue you? These magic cannons were dug out from under the White Tower of the Imperial Palace?

It's better not to say it.

As for the quantity...... Considering Dean Carmen's psychological endurance, Chen Daolin only reported a conservative figure.

"More than fifty. ”

Just this number has already plunged the Academy of Carmen into silence for a long time!

Carmen stared at Chen Daolin for a long time before exhaling: "Okay...... You're really, really...... What a ......."

It's been a long time, and I haven't seen Dean Carmen say the following words.

"I don't care where you got this stuff - I won't ask if it's specific. Anyway, you guy always gets something out of the ordinary. It's just that...... With such a sharp weapon, I feel much more at ease. ”

Dean Carmen couldn't wait to walk over and inspect the magic cannon up and down several times. Then there was a sigh of relief.

It's not a copycat, it's a magic cannon with real value.

Dean Carmen even felt that this magic cannon was better and more complete than the ones stored in the real room of the Academy of Magic. Especially the magic patterns on the base of the magic cannon. It's all very complete.

"Can this tidal magic engine be transported to the city wall?"

"Yes, it's just a matter of building a few storage holes inside the walls, or a few convex pedestals. Well, it's like an arrow tower. Chen Daolin nodded.

"What about the cost?" asked Carmen the most critical question.

"This tidal magic engine you see is a prototype, huh...... Because it's something in the real yàn room. So the materials are more expensive, and the cost of this magic engine is close to 200,000 gold coins. Well, the main thing is that copper pipes are more expensive, and there are some magic gems. Chen Daolin said very bluntly: "Money is not the biggest problem, I can still afford to spend it." But ......"

"But what?"

"You see, this magic engine was built by me alone, and every magic array, every magic symbol, and magic pattern carved on it was done by hand by me, and I carved it one symbol after another. In terms of time, the time cost invested is too great. That's all I've got so far. ”

Speaking of this, Chen Daolin smiled slightly: "If you hadn't come to the northwest, I wouldn't have dared to take out this thing and put it into actual combat." Because I am the only qualified magician here, McQueen and Sasha are too young, I need more powerful magicians, especially magicians with solid basic knowledge, and they must be skilled enough to study the magic array to reach a certain level. At this point...... Sasha is an alchemist, although she is a little younger and more frizzy, but she can barely give me a hand, and McQueen is a student of necromancy, so he can't help at all, so ......"

"I'll help you solve the manpower matter!"

Carmen waved his hand and said in a firm and crisp tone: "I have brought so many magicians this time, and among the more than sixty people, I can always pick out seven or eight that meet your requirements...... It's really not good, I'll help you make zuò with my own hands!"

"Of course that's good. You are the leading figure in the wizarding world of the Empire. Chen Daolin smiled.

"One magic engine can be connected to twenty magic cannons, that is, if you have fifty magic cannons in your hand, you need at least three magic engines. One costs 200,000 gold coins, that's 600,000 gold coins!" Carmen frowned.

Although the Academy of Magic was originally a place of extreme money-burning, and the amount of money invested in magic research and magic practice every year was also huge, it was ...... 600,000 gold coins is still a huge number!

The entire Academy of Magic. The entire cost of a year is more than one million gold coins.

The total annual financial income of the entire Roland Empire is only tens of millions of gold coins.

In other words, the Roland Empire is willing to use about three percent of its financial income every year to support an academy, which is actually extremely generous.

"600,000 is definitely not enough. Chen Daolin smiled bitterly: "Although it is said that a magic engine can be connected to a maximum of twenty magic cannons, it is not such a simple calculation when it is actually put into actual combat. ”

"Oh?"

Chen Daolin sighed, quickly walked to the table on the side, took out a pen and paper, wrote and drew on it.

"You see, this line is like the main fortress wall of the Northwest Fortress. If you want to achieve the best firing of the magic guide cannon, and achieve the best coverage and damage effect, if you only have three firing points on the city wall, it is definitely not enough! It is necessary to form an area coverage to achieve the best results. So, the distribution of artillery points must be spread out, I have calculated, according to the length of the city walls, and the estimated distribution of enemy attack points, we need to place at least six or eight firing points on the walls, well, preferably eight!

Eight distribution points, that is, eight of these magic engines are needed. You can't have too many magic cannons with one engine link. Keep it at five to ten doors optimally. This maximizes the maximum power and ...... If there are too many external plug-ins, more magic cannons will have to be placed farther away when the decorations are arranged...... I can't find a better conductor for energy channeling. Therefore, there will be a loss of energy in the process of channeling, that is, theoretically, the farther away the magic cannon is from the magic engine. Then the greater the loss of mana. ”

Chen Daolin's words, Dean Carmen probably only understood five or six percent, but this did not affect her understanding of the meaning of Chen Daolin's words.

"Six engines...... Other words. Need...... One and two million gold coins?"

"It's better to have eight stations! Eight distribution points, the lethality is even greater. Chen Daolin looked at Carmen's brows and frowned, and hurriedly smiled: "But...... The cost of this 200,000 gold coin unit is the cost of the real yàn room, and when it is actually put into production, because it can achieve the help of more skilled magicians in production, and in addition to the many unnecessary failures and losses in the real yàn manufacturing, I have calculated that if it is mass-produced according to eight units, the cost of each unit can be compressed to about 150,000 gold coins. ”

“...... Eight units, each with 150,000 ......" Carmen smiled bitterly: "This is not 1.2 million gold coins. That's all the money for a year at the Academy of Magic...... Moreover, it will only be used up by several academies, and it will have to support the research costs that can maintain so many magic laboratories. ”

"One and two hundred thousand is a bit much. Chen Daolin smiled bitterly.

In fact, Chen Daolin himself was also a little struggling.

He's very rich though, yes. But...... His money isn't endless either.

At the beginning, in the underground treasure house of the castle of the Rollin family, he got a fortune left by Du Wei.

But even gold and silver always have a time to run out.

He engaged in construction and production in the northwest enclosure, to feed more than 10,000 people to eat, drink and lazar every day, to feed the army, and to devote himself to his own magic and research......

People ask for money for eating, drinking, and Lazar, right?

It costs money to dress and build a house, right?

War horses ask for money, right?

Weapons and equipment cost money, right?

Especially with more than a thousand troops in the military group, this is a huge gold-swallowing beast!

With Chen Daolin's wealth, he is also a little frightened when he spends it.

Even now, although it can still be supported, it is really a little scary to continue to spend like this.

"If you really want to put it into actual combat, 1.2 million gold coins is just the cost of the magic engine. Chen Daolin smiled bitterly: "If you want this thing to sound...... There are also those that cost. The coals used to burn the furnaces, the living elements, and ...... I need to build a few windmills behind the city to draw the wind element...... Well, there are other seven-seven-eight-eight inputs. I calculated it, because I had to consider the cost of blast furnaces, coal fires, the loss of magic arrays, the loss of magic materials, and so on, so ...... In addition to the cost of 1.2 million magic engines, each magic cannon, firing a cannon, costs more than 500 gold coins. ”

500 gold coins in one shot...... Fifty magic cannons, one salvo, it will cost 25,000 gold coins!!

Where is this war? It's like throwing gold out and killing people!!

“...... It's already a lot better. Although Carmen frowned, she also had to sigh: "This is already a huge breakthrough for you, according to the current research of the Academy of Magic, it will cost half a ton of magic crystals to fire a magic cannon." The transduction of energy is too expensive. ”

Compared with half a ton of magic crystals and five hundred gold coins, the latter is naturally cheaper.

Chen Daolin thought to himself, I'm talking about fifty doors...... In fact, there are 100 cannons in total.

A salvo of a hundred magic cannons is 50,000 gold coins......

Fifty thousand gold coins!

A small local aristocrat like Baron Pierre could not earn so much money in a few lifetimes.

As soon as the cannon sounded, there were ten thousand taels of gold. That's all right.

Carmen closed her eyes and pondered, and after thinking for a long time, the dean suddenly walked over to the table and summoned a piece of parchment from her own storage ring.

I picked up the pen and wrote a few lines on it, and then I printed my ring on it with fire paint.

solemnly handed over this piece of paper to Chen Daolin.

"This is the maximum financial support I can give you within my authority. Carmen sighed: "Although I am the chief member of the committee of the Academy of Magic, after all, ...... I'm not really a dean, I'm just a branch dean. So...... That's all I can have access to for the Academy's funds. ”

Chen Daolin picked it up and took a look, saw a few lines of words on it, and saw the bottom line:

"Call ...... 400,000 gold coins......" Chen Daolin raised his head and looked at Carmen.

"That's all there is to it, this year, I'm afraid all the research in the Hogwarts branch will have to stop, and the cafeteria of the house can only eat vegetable leaves!" Carmen smiled bitterly.

400,000 gold coins, it seems that the number is already huge.

But in fact, it calculates......

Based on the calculation of the 100 magic guide cannons owned by Chen Daolin, a salvo of 100 cannons is 50,000 gold coins!

400,000, which is enough for eight salvos. Each magic cannon can only be fired eight times!!If you encounter a fierce battle situation, I am afraid that after a battle, 400,000 gold coins will be gone!

What is this concept?

With a more straightforward contrast, it is obvious.

At least Chen Daolin, who was originally in the real world, knows a common sense, based on the calculation of modern artillery units in the real world, taking the US army as an example, a large-caliber artillery company is generally equipped with eight artillery pieces.

A base number of ammunition is...... 400 rounds!!

The average ammunition for each gun is 50 rounds! Theoretically, each gun can fire 50 shots!

But Chen Daolin is here, 400,000 gold coins...... That's enough for eight shots per cannon......

Eight shells...... When there is a war, it will be a minute away.

"Playing with hot weapons in the era of cold weapons, the price is not ordinarily high......" Chen Daolin silently shed tears in his heart: "If Lao Tzu wants to build a Gundam, I'm afraid that if I throw all the total income of the Roland Empire in a year, I won't be able to smash it."
