There was a sound first, and the shell arrived later, which means it was not traveling at supersonic speed.
However, the speed of sound in this world is about 500 meters per second. Ye Han has measured it, and the error is ±50 meters. Even if it does not exceed it, it is enough.
For example, right now, it was almost to the point where he turned around in horror and could only watch the round shells approaching rapidly, but he had no time to dodge.
Of course, what surprised him the most was that a player had created a cannon?!
Is it that easy to make a cannon?
Melting iron requires a boiler and fuel, and it is best to also understand the effects of the annealing process and trace components on brittleness and toughness; for pouring, a series of process problems such as sand molds, gas holes, and polishing need to be solved...
In this way, you can barely create an outline. Whether it is easy to use or not, and whether it will blow up the chamber, you have to cast it multiple times, change the temperature, the ratio, and the manufacturing process and experiment again and again.
Then we have to get the gunpowder...
You must know that the periodic tables of elements in this world are all different, and the formulas of gunpowder must also be different. Even if Su Xingmou has superhuman luck, Ye Han is not very optimistic about it.
Take the simplest black gunpowder as an example, monosulfide, diniter and trinitrate charcoal. It is easy to say. Even without considering the difficulty of processing, in an era when there was no chemistry and no physical quantities were known, do you know how much each of one, two and three is?
Isn't there a lot of cases where you can't make a product even after you've obviously stolen a secret recipe, but because no one has taught you step-by-step instructions?
Not to mention that the chemical reactions in this world are completely different, so various recipes have to be tried.
Even if you know the formula or a combination of three substances, how do you choose?
Pick from four, and the probability is C43; pick five, and the probability is C53; pick six, C63... You know, the factorial growth rate is faster than the exponential!
What's more, it's not necessarily three types, it could be two, or it could be four, five, six, seven or nine...
Even if you happen to get it right, you still have to get the correct ingredient ratio again...
So even in the 21st century, compared with rigorous mathematical physics, chemistry is still a subject with too many uncertainties, and empirical summaries are always more important than theoretical predictions. Metaphysics even surpasses science.
So after realizing the differences at the micro level, Ye Han never thought about making any breakthroughs in the field of chemistry, even if he was semi-professional.
The laws of mathematics are valid in infinite universes; the laws of physics can also take effect in numerous universes; only chemistry is so sophisticated that it may not work at all in another world.
Unless one day he solves the grand unified theory of chemistry and can directly deduce the properties of elements and the laws of material combination through the laws of the universe, physical parameters, and electromagnetic effects, otherwise he will not waste time.
But...has anyone done it?
Of course!
This is the battlefield of time, with countless elites and talents gathered together.
He feels that where there is no way to go, others may not be able to take shortcuts; he feels that when manpower is exhausted, others may not be able to use firewood to make a bright flame.
For example, the problem of primitive cannons having extremely poor accuracy and difficulty in aiming can be perfectly solved through the strategist skills of the catapult?
The nerve reflex lasted 0.03 seconds, and the signal transmission speed exceeded 300 meters per second. Ye Han thought about so many things in an instant, but it did not help resolve the crisis.
No matter how strong the carbon clothes are, they are still not able to protect against artillery shells!
He is wearing clothes, not tank armor! Even if it is stronger than tank armor, it is only a few centimeters thick. There is no way to neutralize the impact of artillery shells.
Just when he was at a loss, a white shadow suddenly jumped out.
It’s the spirit of war!
A strong force came and Ye Han flew up.
As the clouds flew up in the mist, Ye Han looked back at the white horse and vaguely saw from the horse's head covered by carbon armor: "Finally, I don't have to wait on you anymore!"
(????)
The spirit of war is the spirit horse. The spirit horse recognizes its master.
Although he was temporarily "lent" to Ye Han for some reason, he would definitely not hesitate to be ridden for a while.
So on the high ground on the other side of the mountain, Lao Ma and Lao Cai were stunned to see that just when the cannonball was about to hit, the target was knocked away by the white horse that suddenly jumped out, and then... parabola fell into the cliff.
Yes, Ye Han had been running on the edge of the cliff. The collision of the spirit of war directly knocked him out of the cliff, and he flew very far, and started a smooth free fall!
A second later, Ye Han, who had calmed down, opened his arms, opened the bat wings, and changed from free fall to free gliding.
Yes, in addition to diving, his carbon jumpsuit also has the function of a gliding suit, which can be opened at any time. Then, the parachute is also logically folded in the system backpack.
As a fiber athlete, even if I can't bring it on the plane, I still can't bring a parachute?
Thanks, Spirit of War!
Spirit of War:(￣(?)￣)
As a mount, it is absolutely not okay to openly kill the owner! It is not even allowed to disobey the owner's orders. Only in special circumstances, such as the one just now, can you choose the lesser of two evils.
It chose to crash into the air. Firstly, it could give Ye Han a whole corpse, which was "lighter" than death without a whole corpse. Secondly, it could relieve his anger. After being ridden for so long, he came back in person to take revenge. It was so happy! Refreshing! So enjoyable!
Never imagined……
What it didn't even expect was...
"That horse, that horse is not dead?" It was still on the high ground on the other side of the mountain, where Lao Ma and Lao Cai pressed their chins to their chests.
The cannonball hit, absolutely! This is true regardless of the skill feedback or seeing it with my own eyes.
But it was clearly a hit, hitting the white horse's butt. When the big white butt [Note 1] swung, the huge cannonball was actually bounced away...
(??ω??‖)
This even made them doubt the power of their own cannon.
Actually it's not surprising at all.
The weight of a horse can exceed one ton, which is more than a dozen normal adult humans, and the War Spirit is exactly the tallest and largest horse.
Although the damage tolerance is not based on body weight, it is several times stronger than humans, but there is no problem at all.
It has been trained, and its own attributes are of the highest quality, supplemented by the blessing of internal strength...that is, it is a horse. If it is a human, even if it is not at the level of Lu Bu, it must be at the level of Guan Zhang.
Of course, the most important thing is the armor. Although it is not thick, it is thick at the impact point.
Because it was not struck straight, it was struck on an inclined surface.
We should have known in the second grade of elementary school that the equivalent thickness of armor is the vertical thickness/cos inclination angle.
As long as it is tilted enough, 1cm can be infinitely thick. Coupled with the poor penetrating power of spherical cannonballs [Note 2], isn't it natural that it will be shot away?
It can only be said that Lao Ma and Lao Cai are a bit poor in science.
Me, I'm not dead?
The spirit of war, whose butt was sore after being shelled, opened his eyes and stared blankly at Ye Han, who was freely gliding down. He suddenly felt that everything was dark.
So, not only did he not come back with revenge, but he actually saved this guy by some strange combination of circumstances?
o(??????????)?o
It took several seconds for it to barely recover from the blow, support its body, and limp away, leaving only a melancholy figure behind.
The old horse on the high hill was stunned and suddenly shouted: "Go quickly and keep that horse. It wants to live, not die!"
This horse, this horse is really too strong! Even cannonballs can’t kill it!
If you can stay, the world is so big, where can you go?
