Seeing the strangely shaped weapon that Master Einstein took out, let's call it a gun? At least the shape is similar, although he hasn't started to introduce it, but just from the appearance, Derek has roughly guessed what this thing is, and he was immediately stunned, this TM can also ?!

The whole gun is almost a rectangular square, much longer than a normal gun, especially the barrel part, which is slightly longer than most rifles, and through the transparent ampheina gum covering it, you can clearly see the circle of copper wire wrapped around the barrel, as well as the cylindrical capacitors distributed under the barrel and the butt.

That's right, this is actually a one-man electromagnetic cannon!

"How did you make this thing?"

"It's all up to your textbook, young master, isn't there something called an electromagnetic cannon on it? We tried it, but we didn't expect it to succeed after trying it, but I don't know why young master why you have been addicted to gunpowder weapons, I have to say, in addition to the rate of fire, this weapon is too strong......

"I understand, it's just how do you solve the capacitance problem?" You know, in the previous life, electromagnetic weapons were popular in various science fiction works, and they were completely feasible in scientific theory, but it is not unreasonable that they have not been applied on a large scale in reality.

The biggest problem is the capacitor! Because at least until the time Derek crosses, it has still not been solved, if you want to meet the shooting power of the electromagnetic cannon is not less than other weapons, you need a very fast charge, can store a lot of charge, but also can release the electrical energy in a very short time, but also safe and stable supercapacitors, and the size is as small as possible.

How is this possible, let's wash and sleep, there is everything in my dreams.

"Yes, young master, the cost of this weapon is expensive here, we experimented with a variety of materials for the conductor of the capacitor, and finally chose pure gold as the conductor, although it is a little expensive, but it is really very useful. ”

Derek has nothing to say, if he has to say something, this is a beautiful mistake, although he has been in this world for more than two years, his way of thinking is basically still stuck in his previous life, when making weapons, Derek did not think about the super kinetic weapon of the electromagnetic cannon, but thought of the technical problem, and finally gave up.

However, he forgot one thing, although the world generally follows similar physical laws as in previous lives, there are still many differences, such as the periodic table that is much richer than in previous lives! Even Derek can't be sure if those strange things are still elements.

After all, scientific research has shown that non-elemental substances do exist, well, it's my fault to talk about science in the world of magic~

Derek looked at Master Einstein's excited expression of triumph and longing for his own praise, as if he heard someone say: Wake up!

Isn't that my line?!

"This electromagnetic cannon uses a coil-type acceleration device, with a rate of fire of 1.2 seconds per round, although it is a bit slow, but it is very powerful......" Master Einstein was still babbling about the performance, and Derek had no patience to listen to it, and pulled the trigger on the freshly changed steel beast-shaped target.

The cannon made a faint and almost negligible sound, and then accelerated the projectile until it collided with the target, and then there was a crisp "bang!"

Without exception, the beast-shaped target made of Derek Special Alloy Steel has an additional transparent hole of the same caliber as the electromagnetic gun.

As for the final weapon scheme of this set of magic armor, Derek also made a decision in his heart.

Three days later, early in the morning, Princess Wei'er hurriedly picked up two mouthfuls of food, and then rode away in a hurry, taking the sword symbolizing the identity of the head of the regiment that Derek received from the old Henry when he handed over, and set off for the Dragon's Tooth Legion, so there was a rare silence at the dinner table, Derek leisurely finished breakfast, sat on a chair while sipping black tea, and wrote and drew on paper.

At the strong request of Princess Wei'er

"Master, wouldn't it be bad to bully Her Royal Highness Princess Wei'er like this?" Miss Lina asked with some concern, filling the cup that Derek had finished drinking again.

Derek didn't raise his head, and while drawing, he replied, "You heard it, she asked for it, I didn't force her." ”

"The master is really bad-hearted~" Miss Lina is so gentle even when she complains.

While he was talking, Butler Tamu came in and reported, "Young Master, the goblin boys in Hongqiu Town have been preliminarily screened, do you want to conduct the selection today?"

"That's right, is Kaka back?" Derek then asked, in Derek's vision, the goblin boys would exist as artillery and ranged infantry, and melee combat would rely primarily on orcs.

"Not yet, I guess I should be able to come back from Oak Town today. The butler replied.

"Then it should be afternoon, let's go, Uncle Tam, and go see my excellent goblin boys first. Derek finished the final strokes on the paper, glanced at Miss Lina with satisfaction, and stood up.

"Young master, please. ”

The selection took place in the Colosseum of the Windy City, which was one of the largest gladiatorial arenas in the entire kingdom of Ryan before the old Earl Ross drafted the Emancipation Proclamation, where captured slaves brutally fought each other in order to please the nobles who were high above them with bloody images, in order to just live.

And now, it is completely open to the public, and it has become a place for citizens to walk and have fun, and every weekend, a simple amphitheater is set up to put on some fashionable plays, and before Count Ross arrives, the goblins who arrived early begin to whisper to each other like starchasers.

"Did you say the young master would come?"

"Why not, I heard from my cousin that the young master came to select soldiers in person today, if I can fight for the young master, I am so happy!"

"I warn you, don't rob me, the position of the young master's personal soldiers must be mine!"

"Get out!, I'm the young master's personal soldier, and my grandfather has served the old earl!"

......

"Everyone, be quiet!" the mage of the City Defense Legion, who maintained order, flew over the gladiatorial arena, shouting loudly with amplification.

The Ross family's popularity here is incredible, and Derek only sent out a conscription news, which made almost all the young goblins in Redhill flock to it, and even did not hesitate to fight in order to grab a spot, which is simply impossible in other realms.

On the one hand, it is naturally because of the Ross family's contribution to the liberation of foreign races and years of governance, and on the other hand, because the goblins are the most science-conscious race in the world, and Derek, who has written so many textbooks, is tantamount to a god-like existence in their eyes.

The system of the Kingdom of Lane is very interesting, while allowing a high degree of autonomy of the noble realms, and even the city defense corps can command, it has no influence on all personnel appointments and dismissals of the city defense legions, and all the positions of the city defense legions can only be appointed and dismissed by the legion commander, and the appointment and dismissal power of the legion commander is in the hands of the king.

"Young Master, Young Master......" Suddenly there was a loud cheer, and the sound shook the sky, making the Fa that had just improved the order somewhat useless.

Derek's appearance made the scene immediately out of control.
