With Roddy's words, the group of old fellows were able to freely ask questions.
At first, they still put on airs and asked some simple questions. The answers they got were all within their expectations. However, when Crupus asked about the "metal alloy smelting", Stika and Essien explained the "heat treatment" magic circle that they made together for a long time.
This question obviously involved some very deep professional knowledge. Dragons usually did not need to forge or smelt anything because Dragons had never needed armor or weapons. They trusted their claws and magic more. However, the strength that the Kallon Kingdom had displayed in the war had caused them to gradually change their views. As lords and elders, they had already begun to research in this area. However, their theoretical knowledge came from the summaries of the humans, High Elves, and other races. If they wanted to innovate, they could only make some simple improvements. There weren't many outstanding results.
However, in this field, the "Strategic Arms Research Department" had accumulated a lot of research results in order to develop qualified missile shells. Crupus was originally curious about how to smelt. After listening for a while, he realized that the "furnace" they used was not ordinary at all. "You mean … this improved furnace magic circle can accurately control the temperature and even adjust it quickly?"
Most people's concept of "furnace" was "high temperature". The higher the temperature, the better. The Dragons were more knowledgeable. They knew that some things needed to be controlled properly. However, the way they controlled it was to control the fire element. However, this led to a result. It was fine when the temperature was low, but the higher the temperature, the harder it was to control. A slight mistake would cause fluctuations, and the result would be a big error in the experiment.
However, Essien and the others had already made a furnace powered by crystal energy. The improved magic circle could easily stabilize the temperature. If they wanted to adjust it, they could directly operate on the magic circle. Moreover, the structure of their furnace was more advanced. The highest temperature that could be reached was an order of magnitude higher than the furnace that the lords and elders knew.
After a few questions, most of the elders fell silent. The premise of "teaching the younger generation" was that one knew more than the other. However, it seemed that these young honorary elders had really done something that they could not do.
"Essien, can this thing really achieve the effect you said?"
Lord Crupus couldn't help but ask. Dragons' magic wasn't omnipotent. It was not a problem for a fireball spell to reach 2,000 degrees Celsius, but maintaining it for an hour was something that the current magic circle could not do. However, the combination of the furnace and the magic circle made them realize that it was possible.
"Your Lordship, this is the latest improvement plan. The furnace in the Dragon Tower can already achieve the effect you mentioned."
Essien's reply caused the group of Elders to widen their eyes. They had finally realized that … the things that this group of young Dragons were researching were indeed more "advanced" than they had imagined. In some aspects, they had even surpassed this group of Demigods!
Precision was an important indicator of industrial standards, but physics theory was the foundation. The elders who were originally interested in the "strategic missile" quickly turned their attention to Kardashian's blackboard and notes. The formulas and theorems left by countless great people on the earth were like shining gold, immediately attracting the elders' attention.
"Are these numbers?"
Lord Victor finally spoke. He had never seen Arabic numerals before, but he could guess their use.
"Yes, they correspond from 1 to 10." Kardashian stepped forward to explain, but Victor quickly pointed to the letter ρ and asked, "What do these represent?"
"It is used to represent the density of an object."
"Density?"
Dragons also had a similar concept, but there had never been a unified name for it. This reaction was the same as when Kardashian first came into contact with it. Therefore, she patiently explained the meaning of the formula and the calculation method. When Victor saw countless materials classified according to their density, melting point, and other properties, the original intention of "teaching" had completely disappeared …
The elders collectively fell silent. The content after that was more like a group of people asking questions in a professor's class. However, the person who answered was Kardashian, and the ones who asked questions were them.
"These formulas are also used to assist in the calculation, hmm? This, this is the draft of the calculation. You asked the method, I used calculus … Hmm, differentiation and integration are like this — "
The scattered formulas on the blackboard were asked one by one because these formulas looked simple, but the value behind them was difficult to estimate. Middle school students knew that F = ma, but before Newton explored this law, "scientists" were basically studying philosophy or theology. The profound meaning of the three laws of mechanics was not understood by most people living in modern times.
"The shoulders of giants" was not a joke. The sudden appearance of Kardashian's formulas in this era was no less than ten thousand nuclear bombs.
The elders simply could not accept that the theorem that was applicable to almost everything was expressed in such a simple formula. The world was so complicated, how could it be calculated so carelessly?
Of course, Kardashian did not tell them about quantum mechanics. After all, humans on Earth still had not found a unified theory that was applicable to gravity, electromagnetic force, and strong and weak interaction force. However, at the current level of research, the laws of macroscopic mechanics were sufficient.
In order to better express this formula, Rubens began to use the existing experimental equipment to do demonstration experiments on the spot. Verifying the theorem F = ma was very simple, so he, who hated data calculation, could easily do it. Not only that, the Black Dragon Herrlöw could even explain "Hooke's Law" to Lord Pukasto. Of course, in this world, it was known as "Kardashian's Law".
"Actually, it's not just the choice of materials. After understanding this law, when facing an enemy, you can use the least amount of force to deal the most powerful blow."
The Black Dragon Herrlöw worshipped power, but not brute force. Lord Pukasto could not help but clap his hands and sigh after hearing Rubens's words. "According to this law, there is room for improvement in many spells … and the room is very big."
While the conversation was lively, Roddy suddenly said, "If you have any questions, you can also ask. We are facing a common enemy, right?"
After he said this, the elders and lords remembered that Basta and the other four were also following behind. However, they were like mutes after entering the laboratory. From the beginning to the end, they did not say a word. Seeing the scene of the lords and elders asking questions in front of Kardashian, anyone with a normal brain would understand what this meant …
"We, we can just listen by the side …"
Aglais stammered. Roddy stared at them for a while. When they were a little scared, he nodded and said, "Okay, the Strategic Arms Research Department is not open often. If you have any questions, take the opportunity to ask."
