Zhang Tie immediately put away his Chaos and revealed his face. Closely after that, he threw a glance at the other 4 people in Castle of Black Iron as he burst out into laughter…
“Edward, well done. Your spears are indeed great. Your judgment is right. In kinetic energy strike, round-end spears indeed face fewer air-resistance than pointed-end spears at higher speeds in flight…”
Edward was overwhelmed by an unexpected favor. Therefore, soon after he straightened up, he bowed towards Zhang Tie once again as he said, “It’s my honor to serve Castle Lord!”
These days, Zhang Tie and Edward were producing proper spears in Castle of Black Iron. After hundreds of times’ experiments, Zhang Tie finally fixed the most proper weight of his spear as 680 kg on the premise that the spear didn’t weaken his velocity of throwing. Although Zhang Tie could also throw a heavier spear; his velocity of throwing could not be such great. In general parison, they finally fixed this weight.
In the beginning, Zhang Tie’s and Edward’s opinions were divided on the pattern of spear. In Zhang Tie’s opinion, when a spear flew at a high speed, its end should be pointed in order to reduce the air resistance; however, Edward insisted on that the end of the spear should be a bit rounder. In order to convince Zhang Tie, Edward produced spears in different patterns for Zhang Tie. After having a try, Zhang Tie found that round-end spear could really fly faster than sharp-edged spear on the premise that they had the same weight. It was out of Zhang Tie’s imagination that sharp-edged spear had to face a greater air resistance than a round-ended spear in flight.
A row of spears with round ends and sharp ends were put behind Heller and the other 3 servants. Each spear was about 2 m in length. Being made of gold, they looked very brilliant and luxurious.
It was out of Zhang Tie’s imagination that he could use golden spears one day. Before producing golden spears, Edward had made some spears using navyblue iron. However, at the sight of those spears, Zhang Tie almost burst out into laughter.
The thick parts on both ends of those spears made of navyblue iron were 20 cm in thickness; however, the middle part of the spear turned slim for the sake of hold. This structure looked weird and funny. It looked like a sausage on a bamboo stick. At the sight of the slim waist and the thick ends of the spear, Zhang Tie couldn’t help but laughing out.
Zhang Tie didn’t want to arouse laughter when he intended to kill his enemy by spear in an imposing manner one day.
Additionally, the body of spear made of navyblue iron was too thick; of course, it would face a greater air resistance in flight.
In this case, even though Zhang Tie disliked being luxurious, he had to allow Edward to build gold spears for him as gold was the best high-density metal for making kinetic energy weapon.
Due to a greater density, the golden spear was smaller than half the size of a spear made of navyblue iron. Zhang Tie didn’t feel improper holding it; additionally, he could casually make some poses with a golden spear. With a golden spear in hand, he felt having a much greater qi field than that of the “sausage”. Therefore, Zhang Tie accepted a golden spear.
Zhang Tie walked over there and took up a round-ended spear and a sharp-edged spear by holding the middle part of the golden spears at the same time. After paring with the ends of the two spears carefully, Zhang Tie asked Edward, “Why does this round-ended spear face a smaller air resistance than a sharp-edged spear in flight?”
“Castle Lord, in low-speed flight, sharp-edged spear definitely meets a smaller air resistance than that of a round-ended spear; however, it’s reverse in hypersonic flight. It’s involved with very plex aerodynamics and thermotics in hypersonic flight. Some indistinctive features of some objects in the mon state would grow significant in the hypersonic state. If Castle Lord wants to know the reason, please refer to the self-similar solution of the flow boundary layer equation of laminar flow in hypersonic speed. The convective heat transfer on the end stagnation point is inversely proportional to the square root of the radius of curvature on the end. By making the end a bit rounder, we could reduce thermal load.”
When it came to his profession; although, Edward still remained humble, his voice undoubtedly sounded like that of a master.
Zhang Tie blinked his eyes. He understood every single word of Edward; however, he didn’t understand the meaning of the total paragraph. Even though Zhang Tie was a master artisan, he still couldn’t understand Edward’s words.
Only after thinking about Edward’s words for 0.1 seconds, Zhang Tie had given up his exploration in this question. He was neither an engineer nor a scientist, he only cared about the result. He only cared about the result. He only wanted to know which sort of weapon was more proper and powerful for him. Through this thing, Zhang Tie understood that the so-called mon sense had their limits. Almost everyone knew that sharp-edged objects would face smaller air resistance in flight than round-ended objects; however, if hypersonic flight, this mon sense was wrong.
“Can you make this spear more powerful?”
“If we use platinum to make a spear, due to its greater density, this spear could be about 10% smaller while its air resistance would reduce by some percentage points on the same weight. Additionally, we could add a consolidating rune and a sharpening rune to it…”
“Well, no need to use platinum. We don’t have more platinum than gold in Castle of Black Iron. Just make them in gold. I don’t care about the trivial difference in size and air resistance!” Although Zhang Tie hesitated a bit at the beginning; after making his decision, Zhang Tie said, “Make 2,000 golden spears for me!”
“2,000?” Edward reconfirmed it. After seeing Zhang Tie nodding, Edward immediately nodded forcefully and pleasantly.
“Let’s go back to the palace tree. I’m a bit hungry…” Zhang Tie walked towards the palace tree below the mountain peak, followed by the 4 people.
Each spear would consume him 680 kgs of gold. After throwing out each gold spear, Zhang Tie would lose 27,200 gold coins. Although it seemed wasteful, it was nothing pared to the life of a black iron knight.
After taking the latest fruit of brilliance, Zhang Tie’s spiritual energy bulged once again. The latest fruit of brilliance could almost match that of Han Zhengfang and Han Yuanhong in spiritual energy; because this new one contained the spiritual energy of the 2 throne pastors and the 5 chief pastors, along with the other pastors, chief pastors and over 10 officials on the flagship of Sacred Light Empire.
With bulging spiritual energy, Zhang Tie gained a greater flight speed, a more destructive kinetic energy strike. After hundreds of tests, Zhang Tie was sure that he could kill a black iron knight with a 680 kg’s golden spear; even if the black iron knight released his protective battle qi. When the energy of 12.9 billion Joules focused on one point in milliseconds, it was much more destructive than any alchemist bomb or tons of TNT. Alchemist bomb’s or TNT’s explosion affected a wide area in a short period; however, kinetic energy strike focused on one point.
From then on, black iron knights were nothing but sh*t in front of Zhang Tie.
Zhang Tie finally sensed how imposing was a divine dominator. The one who could determine a knight’s destiny was the real dominator!
This might be the real bat mode for a divine dominator. After grasping the secret of kinetic energy strike, he had various bat modes; instead of being limited to the bat mode that cut through the opponent by sharp weapons which were very preliminary for a divine dominator.
Actually, Zhang Tie had grasped 3 bat modes as a divine dominator. First, having sharp weapons cutting through the opponent; second, make kinetic energy strike by golden spear; third, make a kinetic energy by the 6.8 ton Thor’s Hammer at the speed of 13 times greater than the speed of sound. As for the third bat mode, he could release the energy of 60-70 billion Joules and easily kill earth knights.
…
Zhang Tie felt pretty good today. Therefore, he had a good appetite and enjoyed the yummy food in the dining hall of the palace tree.
After having a yummy dinner, the dark fell in Castle of Black Iron which indicated that it was also dark outside…
After leaving the dining hall, Zhang Tie entered a warehouse of palace tree alone, which was filled with various plant seeds.
‘It’s time to solve another problem…’
