At this moment, the soldiers on the roof who were about to stand up and launch the "Big Sky Monkey" in the bamboo tubes on their shoulders were firmly suppressed by the Japanese fire base and were unable to launch an attack.
"???..."
The three elongated whistles were still loud and clear despite the heavy gunfire on the battlefield. At least the soldiers operating the gasoline cannons on the roof could hear them clearly.
"Test fire one round, prepare... to ignite."
Still, someone took a cigarette butt and lit the torch reserved on the front of the gasoline canister.
What is strange is that the cannonballs loaded into the gasoline cylinders have a streamlined cover. Not only that, but the periphery of the cannonballs are also made of curved bamboo pieces to make multiple short wings that automatically open when facing the wind.
Maybe many people in this era cannot understand these things, but for people in the future, these things are just basic common sense.
The fairing will reduce wind resistance, and the curved and symmetrically arranged bamboo pieces can ensure the rotation of the projectile, allowing the projectile to fly farther. As for some other tiny designs, you cannot see it from the appearance of the gasoline cannon cannon without firing.
"Tum..."
Due to the large caliber, the sound of these shells when fired is quite dull.
At least no soldier on the battlefield has ever heard the sound of this kind of artillery shell being fired.
What is even more different from what is recorded in history is that these huge flying cannonballs suddenly ejected tongues of flame from behind their buttocks in the air.
Bottom exhaust bombs were a fantasy during World War II, especially in China, which was extremely backward at that time.
However, physics and chemistry are unchanging truths in any time and space, and they are the only ones in this world that can be verified or falsified. As for the others, they will change with time, place, and people.
For example, who would have thought that eighty years later, someone would dare to ask Qin Hui to overturn his case, and some people would actually become traitors just because they liked comics or Japan's obscene culture.
But no matter how thoughts change, the theorems and formulas of physics and chemistry will not. Even if new discoveries are made that can falsify past theorems, they can still be proven or falsified.
This is why the smartest people among humans choose to believe in science.
It is also a truly powerful country, and what it plays is mathematics, physics, and chemistry. As for other things, it is enough to summarize it by saying, "If you fall behind, you will be beaten."
Fairings and extended-range rockets are installed on the shells of gasoline barrel cannons, which greatly increases the range and controllability of this basically inaccurate weapon.
However, it still maintains the characteristics of a gasoline barrel cannon, that is, the cannonballs fly slowly.
At this time, almost everyone on the battlefield was staring at the large cannonball flying slowly across the sky, trailing tongues of flame.
Watching it pass the highest point of the parabola, then turn around and go down.
At this time, people who know how to use a sight or telescope to measure distance can silently read its distance.
"Four hundred meters, it's unimaginable that this thing can actually hit a distance of four hundred meters."
As mentioned before, this kind of gasoline cannon has not been tested, so this time all the gasoline cannons were tested. Therefore, there was more than one large and slow cannonball flying by.
Watching the cannonballs falling from the skylight, some Japanese soldiers holding steel shields placed the sharp-edged shields on the ground and at the same time pulled apart the two supporting wooden rods behind them to support the shields.
Then he quickly covered his ears and opened his mouth wide.
Everyone's eyes were fixed on the big cannonball flying through the skylight, and they wondered what kind of violent explosion it would cause when it hit the ground.
However, the result was destined to be disappointing. Not only the people in Sihang Warehouse were disappointed, but the Japanese soldiers were also very disappointed.
Except for the Japanese soldiers at the fire base who were constantly pouring ammunition onto the roof of the Sihang Warehouse building, almost all other actions on the battlefield stopped.
Including the soldiers in the Sixing Warehouse, they all wanted to see what kind of surprise Commander Zhang's new gadget would bring to them.
Thinking about such a large cannonball is very impressive.
However, to everyone's disappointment, none of the seemingly powerful cannonballs that flew slowly through the skylight exploded.
"Could it be a poison gas shell?"
"How is it possible? How could a country as backward as China produce advanced poison gas shells? And did you see it smoking? How could a shell that doesn't even smoke be a poison gas shell?"
Not only were the Japanese soldiers whispering, but even the soldiers in the Sihang Warehouse did not close their mouths, which were half-opened in anticipation of seeing the spectacular explosion and then cheering, but now they reluctantly closed them.
"What's going on? How come it doesn't sound? Could it be that there are charcoal strips inside? It can't be just a bluff."
Xie Jinyuan, who was holding the telescope, was equally confused and disappointed, but he still found the only excuse for Zhang Sixing in his heart. That was that the big thing thrown out must have been equipped with a charcoal time bomb.
Yes, there are charcoal strips used as time bombs, but no one has thought about it. If you dare to think about it from this perspective, you can develop many new uses.
Even Lu Feizhang, who saw this scene from the hole blown by the shell on the first floor, also found a reason in his heart for these shells not to explode.
he thinks:
Back then, when I handed over the public rations to the puppet township office, if there were explosive packets with smokeless charcoal sticks in them...it would be exciting to think about it.
It's a pity that I don't know if it can be used to fight Japanese enemies now.
But it didn't matter what they thought. The gunners of the gasoline barrel artillery team placed on the roof of the building and commanded by the gunners who had escaped from the prison camp received the next order.
The artillery commander, who was holding Zhang Sixing's periscope observation scope, also tested the distance and murmured that there were people around him who could write who were silently taking notes.
"The No. 1 medicine pack is about 80 meters, the No. 2 medicine pack is 120 meters, and the No. 3 medicine pack..."
This is a method for controlling the range of mortars. If the amount of charge is determined, the range can be controlled relatively accurately. Unfortunately, in order to maintain confidentiality, Zhang Sixing did not allow the gasoline cannon cannon to be tested.
"Pack No. 6, target enemy fire base, aim, ignite..."
The commander of the gasoline barrel artillery shell never thought that the word "ignition" would one day be used for artillery.
Following his order, someone went up to load the launcher bag.
Then he took the bamboo tube filled with gunpowder and pierced the propellant pack through the reserved hole, while blowing the cigarette butt in his hand.
People who love smoking love this firing method so much that in order to ensure the firing, everyone is given three packs of cigarettes.
Then the guy who just put the medicine bag picked up a large cannonball and stuffed it into the gasoline barrel.
Looking at the Japanese fire base and the Japanese soldiers everywhere, the commander of the gasoline barrel cannon suddenly thought:
If this row of artillery shells goes down, it is guaranteed to blow them up. Will I be remembered in history because of this row of artillery shells?
