Of course, nodding to nodding and getting them to really ask questions is simply impossible. These five guys are originally second-rate in the clan, and they are negligent in spell research on weekdays, so it is difficult for them to explain a forbidden spell clearly, where can they have the level to participate in the current discussion?

Although the questions raised by these elder lords are not difficult at the moment, and they can only be said to be at the level of high school students, for the dragon clan who have never been exposed to this kind of knowledge, the development of "from point to surface" is almost instinctive. Krups only listened to the role of calculus, and immediately led to the problem of "irregular surface calculation" when building illusion spells.

I have to say that compared to the basic algorithms, calculus is a very awesome tool. Calculating surfaces is one thing, and any problem of continuous change encountered in the construction of spells can be solved with calculus, compared to the stupid methods used by the lords and elders in the past, what this college student has learned in "advanced mathematics" is simply a cloud of mud!

After all, this is a calculation method that can be applied in mechanics, astronomy, chemical and biological engineering, and even economics.

"If it's really that good... Then the problem we just talked about is probably easy to solve. ”

Although the black dragons have a fierce temper, the strength of the lord of Pucasto is not a lie of words. After listening to Kardashian's explanation for more than ten minutes, he first thought of what they had just discussed in the meeting.

"Ah, what you say is true, with this method of calculation, the improvement in spells is probably a leap forward. ”

An elder immediately responded, the group of people on the scene had a super IQ, far from being comparable to a college student, and it was not too easy to draw inferences.

After hearing this, Roddy asked Victor beside him, "The lord has a problem, is it convenient to talk about it?"

"There's nothing inconvenient about this," Victor was thinking about the application of calculus at this time, and when he heard his question, he replied casually: "We were discussing the problem of the demon carapace before, because after the demon Barty became larger, the strength of the carapace far exceeded our estimates, and most spells... None of your hedron cannons can penetrate his armor, and in order to deal with this, discussions are underway to best combat this protection. ”

Hearing his words, the Kardashians looked at each other strangely, but did not speak. The Black Dragon Lord was anxious, and seeing their expressions, he immediately asked, "What, are you also studying this?"

"Truth be told, the 'Strategic Weapons Research Department' is also researching ... Well, similar topics. ”

Kardashian wanted to say "the same", but immediately realized that it was inappropriate to say so, so she hastened to say "similar". She was afraid of causing some misunderstanding, but she underestimated the belly of this group of lords and elders - they are not guys who need to cheat funds in scientific research, hearing Kardashian's words, she was immediately curious: "That... Can you share the results?"

After saying this, the five honorary elders collectively looked at Luo Di, because this thing was casually proposed by Luo Di a few days ago, and whether it was made public or not must depend on what he meant. As the person in charge of the research institute, the Prime Minister was stared at by so many people, and replied with a very calm expression: "Of course there is no problem, we naturally hope that the lords and elders can give some advice." ”

This was said to be nothing wrong before, but now that he said it, the elders understood that he was being humble—the level of research alone, the scattered information that had just been displayed was scary enough.

Kardashian then flipped the blackboard over to the other side, and everyone realized that the other side was also full of handwriting, and there were also several schematic diagrams. Stica, for her part, pulled out a few models from the cabinet on the other side of the lab... Judging from the shape, this is another form of "armor-piercing projectile", but unlike the small-caliber "armor-piercing projectile" that Roddy prepared for the "spar cannon" before, the current model is at least more than a meter long after being made to scale.

In other words, it is about the same size as the "anti-tank armor-piercing projectile" on Earth.

Not to mention its shape and structure, it took a few minutes just to take it out and explain what this thing was fired with, so Roddy also reassembled the hedron cannon and showed them: "We first developed an armor-piercing projectile fired from a turret, and in the future, we will study long-range armor-piercing missiles based on this result..."

"Prime Minister, we all know that your hedron cannon is not small, but now the headache is the carapace problem-" Pucasto used the earth element to condense a hemispherical surface on the spot: "For this kind of curved carapace, whether it is a spell or your cannonball, there is a high probability of bouncing off, and the power of the time will probably be greatly halved." Simply making the shells so sharp, I'm afraid the effect may not be good. ”

Luo Di glanced at it and smiled slightly at this question: "It just so happens that the things that several honorary elders have studied are to solve this problem. ”

He took a step back and left the stage to Kardashian and the others behind him. The five of them discussed a few words in a low voice, and then began to take charge of one piece each, explaining the subtleties of this "armor-piercing bullet" in order.

In fact, the model in front of you is only the core warhead part of the armor-piercing projectile - that is, the armor-piercing core made of high-strength, high-density metal. And as a few people temporarily condensed the "shell" with the elements, the elders and lords understood what the thing called the "Armor Piercing Bullet" was all about.

In this structure, when the front end of the armor-piercing projectile hits the target, the softer part of the material will cause some damage to the armor and deform at the same time, and in the process of deformation, the incident angle of the entire armor-piercing projectile will change accordingly - under the action of force, the high-strength core at the rear will hit the target at a more vertical angle, so as to reduce the probability of being "bounced off".

This is the most widely used anti-tank armor-piercing projectile structure on the planet during World War II, because it has the lowest technical content, but it is so effective to use that there are still many tanks in use today.

Luo Di is not a military fan, but he has a wide range of knowledge, and he still saw this thing on Weibo, but he just felt novel at the time, and he didn't remember the specific model or structure. At this time, he suddenly remembered that he couldn't tell how many kinds of armor-piercing bullets there were, but the basic principle of armor-piercing bullets was to remember - with this as a guiding direction, Kardashian's research progress was naturally fast.

After listening to the explanation, the lords and elders were skeptical: can the warhead be automatically aligned with different materials?

However, this group of cutting-edge people is not worried that the theory cannot be verified. Pucasto directly assembled a similar warhead by condensing earth elements of different densities on the spot, while Victor used the frost shield to simulate a carapace with arcs.
