The Chaos Armor was suddenly put away by Zhang Tie, revealing Zhang Tie's face under the armor. Zhang Tie glanced at Heller and others and laughed...
"Edward, you have worked hard these days. The flying spear you made this time is indeed good. Your judgment is right. In kinetic attacks, the round-headed flying spear is indeed better than the pointed one during flight. The flying spear has less resistance and is faster..."
Edward was flattered, and his straightened waist bent down to Zhang Tie again, "It is an honor for me to serve the Lord of the Castle!"
In the past few days, Zhang Tie and Edward worked together in the Black Iron Castle to trial-produce a flying spear suitable for his kinetic combat skills. After hundreds of experiments, Zhang Tie determined that he could currently use it without affecting his throwing speed. The optimal weight of the flying spear used is 680 kilograms. Although Zhang Tie can throw flying spears exceeding this weight, the throwing speed will not be that fast. After comprehensive comparison, this weight was finally determined.
At the beginning, Zhang Tie and Edward had some differences about the style of the flying spear. In Zhang Tie's view, when the flying spear is moving at high speed, the top part of the flying spear naturally needs to be sharper. Because this can reduce the resistance of the flying spear in the air, but Edward insisted that the head of the flying spear should be rounder and there was no need to make it too sharp. The two people had differences, and Edward simply made different styles of flying spears. Let Zhang Tie experience the effect for himself. Zhang Tie just experienced it and really found that the flying spear with the same weight and the round head made according to Edward's plan can indeed fly faster and encounter less resistance. And the flying spear built with his own plan. Although the head is sharper, when flying in the air. The resistance will be greater than Edward's round-head flying spear.
At this moment, behind Heller and Edward, there was a row of different flying spears. There are round-headed ones and pointed ones. Each of these flying spears is almost more than two meters long, shining with golden light. Each one is made of gold, making it look very gorgeous and luxurious.
Zhang Tie initially did not expect that he would one day use flying spears made of gold. Before these golden flying spears were cast, Edward actually used sea blue iron to cast several flying spears for Zhang Tie, but those few flying spears were cast After coming out. Zhang Tie almost laughed when he saw it.
Because the thickest part of the flying spear body made of sea blue iron is almost as thick as the mouth of a bowl, and the middle part of the flying spear body becomes smaller, making it easier for Zhang Tie to grasp it with his hands. The structure of the flying spear, which is thick at both ends and thin in the middle, looks a bit weird and funny. From Zhang Tie's point of view, such a flying spear is just like a string of sausages prepared for barbecue. The small waist and the excessive thickness of the flying spear are extremely fascinating. If you take a closer look, it will make you laugh.
Zhang Tie didn't want to make people laugh one day when he took out his flying spear majestically to kill the enemy.
Moreover, the 680-kilogram aquamarine iron flying spear is too bulky and not agile enough. The resistance of flying in the air is naturally greater.
In this case, even if Zhang Tie usually doesn't like luxury. But he had to agree to let Edward use gold to make a flying spear for himself. As the first choice for kinetic energy strike weapons, high-density metal is the best material.
Gold is very dense. The 680 kilogram golden flying spear was made, and its size was only one-half of the flying spear made of sea blue iron. Zhang Tie did not feel out of place when he held it in his hand. Moreover, Zhang Tie, who was holding the golden flying spear, Just placing a few broken threads, he felt that his aura was a little different, definitely 10,000 times stronger than taking out a bunch of "sausages". In this way, Zhang Tie accepted the use of the golden flying spear.
Zhang Tie walked over and held the middle part of the flying spear with both hands. He picked up a round-headed flying spear with one hand and a sharp-headed flying spear with the other hand. Two 680-kilogram gold spears. The flying spear was easily held by Zhang Tie. Zhang Tie carefully compared the tips of the two flying spears and asked Edward, "Why does the round-headed flying spear encounter more resistance than the pointed-headed flying spear?" What about smaller ones?”
"Lord Lord, when flying at low speeds, the resistance encountered by a pointed flying spear in the air is smaller than that of a rounded one, but when flying at hypersonic speeds, the opposite is true. There are very complicated things involved. The aerodynamics, thermal and other aspects of the flight state of hypersonic objects. Some characteristics of certain objects that are not obvious in ordinary conditions will become very important in the hypersonic state. If the castle master wants to know The reason, then, can be summarized in one sentence - the self-similar solution of the hypersonic laminar flow boundary layer equation. The convective heat transfer at the stagnation point of the head is inversely proportional to the square root of the radius of curvature of the head. Passivating the head can reduce the thermal load. . ”
When it comes to his own field, even though Edward still remains humble, his tone already reveals an unquestionable master's temperament.
Zhang Tie blinked. He understood the first half of what Edward said, and he also understood every word of the second half, but he didn't know what it meant when put together. Even though he was a master craftsman, what Edward said was beyond the knowledge and ability of the master craftsmen of this era.
Just a tenth of a second after Edward's words flashed through his mind, Zhang Tie gave up exploring this problem. He is not an engineer, let alone a scientist. He only cares about the results. As long as he knows what kind of weapons are easy to use, Just let your combat power explode. It was only through this incident that Zhang Tie understood that the so-called common sense has boundaries. Sharp objects have less resistance in the air than blunt objects. This is common sense. Almost everyone knows it, but if you are skilled in At the speed of sound, this common sense is wrong.
"Is there any way to increase the power of this flying spear?"
"A flying spear made of platinum, because the density of platinum is slightly higher than that of gold. Under the same weight, the volume of this flying spear can be reduced by about ten percent, and its resistance during flight can be reduced by a few more. percent. In addition, this flying spear can be added with a rune of solidity and sharpness... "
"Well, don't use platinum. There is not as much platinum in the Black Iron Castle as gold, so just use gold to cast it. The size and resistance will not have much impact!" Although he was a little reluctant at the beginning, once he made up his mind, , Zhang Tie no longer hesitated, "Make me two thousand first!"
"Two thousand?" Edward confirmed. Seeing Zhang Tie nodding, Edward suddenly became happy and nodded vigorously. He was very excited.
"Let's go back to the palace tree. I'm a little hungry..." Zhang Tie took the lead and walked towards the palace tree at the bottom of the mountain.
Each flying spear consumes 680 kilograms of gold, and 27,200 gold coins are gone as soon as it is thrown. This seems a bit wasteful, but if a golden flying spear can kill a black iron knight, then this investment is nothing.
After eating the latest Fruit of Glory, Zhang Tie's mental power increased sharply again. The latest Fruit of Glory was almost as good as the Fruit of Glory put together by Han Zhengfang and his son, because that Fruit of Glory not only contained Holy Light. The spiritual power of the empire's two throne chief pastors, the five scepter chief pastors, the various levels of pastors and chief pastors of the Holy Light Empire on the flagship, and some officers added up to more than ten people. The spiritual power of those people is also contained in this latest glorious fruit.
The sudden increase in mental power has brought about another improvement in the flying ability of the Divine Control Master. The power of Zhang Tie's kinetic energy strike has been enhanced again. The higher flight speed, coupled with the 680 kilogram level golden flying spear, after a while After the inspection, Zhang Tie was able to confirm that the kinetic strike power of the 680 kilogram golden flying spear he was currently using was enough to kill the black iron knight. Even if the black iron knight turned on his protective fighting spirit, he would be killed by his own flying spear. 129 The power of billions of joules of energy concentrated on one point in a microsecond is definitely ten times more powerful than the explosion of some alchemical bombs or several tons of TNT explosives, because the attack of these two is concentrated on one point and explodes instantaneously. An attack spreads over a large area and explodes in a short period of time. Because the difference between the explosion method and the time of the explosion is huge, the power is naturally different.
Today, the Black Iron Knight will be completely reduced to an ant to Zhang Tie.
Now Zhang Tie finally felt how domineering the word "master" of the divine master was and the meaning contained in the word "master" - the person who can decide the life and death of the knight is the master!
This may be the true fighting style of a divine master. Mastering the secret of kinetic combat skills, the fighting style of a divine master will be more diverse and no longer limited to the one he first realized. The fighting method of using sharp and sharp weapons to cut and pierce the opponent is actually very elementary for the Divine Master.
For me now, the fighting methods of my divine master have actually been quietly expanded to three types. The first is the previous one, the second is to use golden flying spears to carry out long-range kinetic strikes, and the third is the same. It was a kinetic strike, but it was a kinetic strike in close combat, just like the strike that sank the flagship of the Holy Light Empire's expedition fleet. The kinetic energy strike of the Golden Flying Spear can kill the Black Iron Knight, and the kinetic energy strike of the 6.8-ton Thor's Hammer at more than 13 times the speed of sound can easily release 60 to 70 billion joules of energy. There are a few earth knights who can easily Can you bear it
…
Zhang Tie was in a good mood today. When eating in the restaurant of Gongshu, he naturally had a great appetite. The table was full of delicacies. Zhang Tie devoured the food with great pleasure.
After eating a delicious meal, the sky inside the Black Iron Castle became dark, which showed that the outside world was also getting dark...
Zhang Tie left the restaurant and went directly to a warehouse in the Palace Tree alone. In this warehouse, there were piles of seeds of various plants.
Now, it's time to solve another problem... (.)
