Chapter 295 Black powder! Fragmentation shells!
"Su Yu, what is your bigger one, which is stronger than the black water jar just now?" Lao Zhao asked.
Seeing Lao Zhao asking, Su Yu picked up the clay pot wrapped in muslin cloth and iron flake flour.
"It's totally a two-level thing.
"The one just now called burning... um, burning canister, it just acts as a deterrent and harassment. 35
"In a humid jungle environment, although a certain number of trees can be ignited because of oil, it is difficult to spread and the real lethality is limited.
"And this thing... hehe."
Su Yu smiled slightly: "Within a radius of 30 feet, there is no cover...you will definitely die! 35
hiss……
Everyone took a deep breath.
The range of thirty feet? Surely death?
With just such a thing?
Facing the surprise in the eyes of everyone, Su Yu did not explain too much.
Instead, he put the jar in his hand on the ground about twenty feet away, and then took out the fire book again.
A faint flame rose, seemingly inadvertently licking the thin cotton thread soaked in the mouth of the can...
"laugh……"
Sparks erupted in vain, and then quickly ignited into the interior of the jar.
shit!
Su Yu's eyes widened, and Sayazi ran back!
Uncle's.
How can the fine linen fuse burn so much faster than the cotton fuse.
While complaining in his heart, Su Yu exerted all his strength to suckle.
That's a full jar of doses.
If you don't run away quickly, he will be the first to suffer.
Seeing Su Yu run wild, everyone's heart thumped.
They had never seen Su Yu so flustered before.
What the hell is this?
The eyes of everyone looking at the pottery on the ground became more and more curious.
"I wipe! Don't look at it, don't die!"
Su Yu, who rushed back in a panic, pushed everyone back to the back of the city gate, and hid behind him.
next moment……
“Boom rumble!!!”
A deafening roar rang out on the ground.
Whether it is the city gate or the earth, it is shaking at this moment.
At the same time, a dense sense of impact came from the city gate that everyone was leaning against.
Blazing pale orange fire waves, accompanied by countless black shadows, spewed in from the open city gate.
Although only fleeting.
But that scorching feeling, everyone did not dare to underestimate it.
I am afraid that it will only be exposed to this fire wave for a moment.
Either burned by the high temperature fire wave, or pierced by the fleeting black shadow.
Everyone looked at Su Yu, who had a lucky face, with a look of horror in their eyes.
What the hell did this guy Su Yu do?
It is already more than twenty feet away, yet there is still such a terrifying power.
No wonder he dared to say that this thing could kill all enemies within thirty feet.
The loud rumbling echoing between heaven and earth gradually receded.
It seems that calm has returned to the outside of the city gate.
Then everyone carefully probed and looked outside.
I saw that the place where the clay pot was originally placed has turned into a huge dark pit.
As for the pottery, the whereabouts were missing, and not even a fragment was left.
All the plants within a two-foot radius were completely burnt.
The heat wave still lingers outside.
Su Yu took the lead out of the city gate's cover and came to the blackened pit.
Looking at such an exaggerated effect, Lao Zhao asked with some difficulty: "Su Yu, what the hell is this...?
Su Yu smiled: "How do you say this thing, I haven't thought of a name yet, so you can call it Fragment Cannonball for now.
In fact, this thing was made by Su Yu based on the principle of modern fragmentation grenades.
By the way, another magic change was made.
In this pot is the black powder he made with the most primitive method.
This thing is far more awesome than most people imagine.
Every 4 grams of black powder can produce 280 liters of gas in a very short time after burning.
The volume can expand nearly ten thousand times.
Therefore, once it is ignited in a closed space, it will produce a great impact force and a small range of short-term high temperature.
It's called an explosion!
In the outer ring of the clay pot with black powder, Su Yu filled it with a large amount of flour and iron flake mixture.
First, because it is to be thrown out by the projector, the flour can play a protective role.
Prevent the clay pot from falling to the ground and breaking before it explodes, and when exposed to the air, it only deflagrates and cannot explode.
The second is to greatly increase the lethality of this "." artillery shell.
After all, relying only on the explosion of gunpowder and the fragments of the clay pot, the lethality of this shell may not be much stronger than that of the oil burning pot.
Fine flour is known to be flammable.
In fact, normally, piles of flour like this are difficult to ignite because of the oxygen content.
But I can't stand Su Yu's professionalism.
He directly increased the proportion of saltpeter powder in the gunpowder in proportion, so that it released more oxygen during the combustion process (Wang Zhao's) to provide the conditions for the flour to burn.
With the explosion of gunpowder, a large amount of flour was ignited and spread out, forming a fire wave of high temperature and high pressure.
The explosion of flour will form a secondary impact again.
At this time, these broken iron pieces in the flour will be given amazing kinetic energy with the double thrust generated by the explosion, and will be sputtered around.
Within this range, nothing is spared.
After the broken iron pieces with rust enter or even penetrate the human body, it will induce tetanus.
Even if he didn't die, it was basically inevitable in this period of Daqin.
After listening to Su Yu's explanation, everyone broke out in cold sweat.
Is this guy Su Yu a fairy or a ghost?
Nima finds something so common and can make such a terrifying fragmentation shell.
