The Chaos Battle Armor was suddenly put away by Zhang Tie, revealing Zhang Tie's face under the Battle Armor, Zhang Tie glanced at Heller and laughed "Edward, you've worked hard for the past few days, the flying spear you created this time is indeed good, your judgment is right, in the kinetic attack, the round-headed flying spear does have less resistance and faster speed than the pointed flying spear during the flight process."
Edward was flattered, and his waist, which had just straightened up, bent down against Zhang Tie again, "It is my honor to serve the castle lord."
In the past few days, Zhang Tie and Edward in the Black Iron Castle together to try to make a flying spear suitable for his kinetic combat skills, after hundreds of experiments, Zhang Tie determined the best weight of the flying spear that can be used without affecting his throwing speed, that is, 680 kilograms, although the flying spear beyond this weight Zhang Tie can also be thrown, but the speed of throwing out is not so fast, after a comprehensive comparison, the weight was finally determined.
In Zhang Tie's opinion, when the flying spear is in high-speed motion, the top part of the flying spear is naturally 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 rounded, there is no need to make it too sharp, the two people had a disagreement, Edward simply made different styles of flying spears for Zhang Tie to experience the effect himself, Zhang Tie just experienced it, I really found that the same weight of the flying spear, the round-headed spear created with Edward's scheme can indeed fly faster, and the resistance is less, while the spear built with his own scheme, although the head is more sharp, when flying in the air, the resistance will be greater than Edward's round-headed spear.
At this moment, behind Heller and Edward, there was a row of different flying spears, some with round heads and some with pointed heads, each of these flying spears was almost more than two meters long, shining gold, each of which was cast from gold, which looked very gorgeous and extravagant.
Zhang Tie didn't 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 a few flying spears for Zhang Tie, but after those flying spears were cast, Zhang Tie almost laughed when he saw them.
Because the thickest part of the spear body made of sea blue iron is almost as thick as the mouth of the bowl, and in the middle of the spear body, it becomes smaller, which is convenient for Zhang Tie to grasp with his hands, and the structure of the flying spear with thick ends and thin in the middle looks a little weird and funny.
Zhang Tie didn't want to make people laugh out loud when he took out a flying spear to kill the enemy one day.
Moreover, the size of the 680-kilogram Sea Blue Iron Flying Spear is too bloated and not dexterous enough, and the resistance of flying in the air is naturally greater.
In this case, even if Zhang Tie usually didn't like luxury, he had to agree to let Edward use gold to build a flying spear for himself.
As the preferred weapon for kinetic strikes, high-density metal is the best material.
The density of gold is very large, 680 kilograms of gold flying spear is made, the size is only half of the flying spear made of sea blue iron is smaller, Zhang Tie held it in his hand, and there was no inappropriate feeling, and Zhang Tie, who was holding the golden flying spear, put a few broken wires casually, he felt that his aura was a little different, it was definitely 10,000 times stronger than taking out a string of "sausages", just like that, Zhang Tie accepted the use of the golden flying spear.
Zhang Tie walked over, holding the middle of the flying spear body with two hands, picking up a round-headed flying spear with one hand, and a sharp-tipped flying spear with the other, two 680 kilograms of gold flying spears were easily held by Zhang Tie in his hand, Zhang Tie carefully compared the tips of the two flying spears, and asked Edward, "Why does this round-headed flying spear encounter less resistance than the pointed flying spear?"
"Lord Castle, when flying at low speed, the resistance of the pointed spear in the air must be smaller than that of the round head, but in the hypersonic flight state, on the contrary, this involves the aerodynamics, thermal and other aspects of the very complex hypersonic object flight state, some characteristics of some objects that are not significant in the ordinary state will become very important in the hypersonic state, if the Lord of the castle must want to know the reason, then, In a word, it is a self-similar solution of the hypersonic laminar boundary layer equation, the convective heat transfer at the head station is inversely proportional to the square root of the radius of curvature of the head, and the heat load can be reduced by passivating the head. ” When it comes to his own field, even though Edward still maintains humility, his tone has revealed an unquestionable master's temperament.
Zhang Tie blinked, he understood the first half of what Edward said, and he understood the second half of the sentence, he also understood every word, but he didn't know what it meant when it was connected.
Even if he is a master craftsman, what Edward said is beyond the knowledge and ability of a master craftsman of this era.
Just flashed Edward's words in his head for a tenth of a second, Zhang Tie gave up exploring this problem, he is not an engineer, let alone a scientist, he only cares about the result, as long as he knows what kind of weapon is easy to use, he can make his combat power burst out.
It's just through this incident that Zhang Tie understands that the so-called common sense has a boundary, and sharp objects have less resistance in the air than blunt objects, which is common sense, almost everyone knows it, but if it is in a hypersonic state, this common sense is wrong.
"Is there a way to make this spear a little more powerful?"
"A flying spear made of platinum, because platinum is a little denser than gold, under the same weight, the volume of this flying spear can be reduced by about ten percent, and the drag of its flight can be reduced by a few 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, just use gold to cast, this volume and resistance, the impact is not great" Although he was a little reluctant at the beginning, but once he made up his mind, Zhang Tie no longer hesitated, "Cast two thousand for me first" "Two thousand" Edward confirmed, and seeing Zhang Tie nodding, Edward suddenly became happy, nodded vigorously, and the whole person was very excited.
"Let's go, let's go back to the palace tree, my stomach is a little hungry" Zhang Tie took the lead and walked towards the palace tree below the peak.
Each throwing spear consumes 680 kilograms of gold, and once you throw it, 27,200 gold coins are gone, which seems to be 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 Radiance, Zhang Tie's spiritual power increased again, and the latest Fruit of Glory was almost comparable to the Fruit of Glory of Han Zhengfang's father and son combined, because that Fruit of Glory not only contained the spiritual power of the two throne Great Pastoral Leaders of the Holy Light Empire and the five Great Pastoral Leaders of the Scepter, but also the various levels of the Holy Light Empire and the Great Pastoral Leader on that flagship, and some officers added up to ten people, and the spiritual power of those people was also contained in this latest Glorious Fruit.
The surge in spiritual power has brought about another increase in the flight ability of the Divine Master, the power of Zhang Tie's kinetic energy strike, increased again, a higher flight speed, and a 680-kilogram golden flying spear, after some testing, Zhang Tie can already determine that the power of his current kinetic energy strike with the 680-kilogram golden flying spear is enough to kill the Black Iron Knight, even if the Black Iron Knight opens the protective combat qi, he will be killed by his own flying spear, The energy of 12.9 billion joules is concentrated in the power of a little burst in a microsecond time, which is definitely ten times more powerful than the explosion of an alchemy bomb and a few tons of TNT explosives, because the attack of one of the two is concentrated on an instantaneous explosion, and the attack of the other is spread out in a large area and short-term burst, because the difference between the outbreak mode and the time of the outbreak is too great, so the power is naturally different.
Today, the Black Iron Knight will be completely reduced to an ant for Zhang Tie.
Now Zhang Tie finally felt how domineering the word "master" was and the meaning of the word "master", and the person who could decide the life and death of the knight was the master This may be the true combat method of a Divine Dominator, the secret of mastering kinetic combat skills, and the combat method of the Divine Dominator will be more diverse, and it will no longer be limited to the one that he realized at the beginning.
The way of fighting, which uses sharp and sharp weapons to cut and pierce opponents, is actually very rudimentary for the Divine Master.
For the current self, the combat method of his own god master has actually quietly expanded to three types, the first is the previous one, the second is to use the golden flying spear to carry out long-range kinetic energy strikes, and the third is also to carry out kinetic energy strikes, but it is a kinetic energy strike in melee combat like sinking the flagship of the Holy Light Empire's expeditionary fleet.
The kinetic energy strike of the golden flying spear can kill the Black Iron Knight, and the kinetic energy strike of the six-eight-ton Thor's hammer at more than thirteen times the speed of sound can easily release six or seven billion joules of energy, and a few Earth Knights can easily withstand it Zhang Tie was in a good mood today, and when he ate in the restaurant of the palace tree, he naturally had a great appetite, and the table was full of delicacies.
After a good meal, the sky inside the Black Iron Citadel darkens, indicating that the outside world is also dark Zhang Tie left the restaurant, and then went directly to a warehouse of the palace tree, which was piled with seeds of various plants.
Now, it's time to address another problem:
