At this moment, the soldiers on the roof of the building who were about to stand up and launch the "big monkey" in the bamboo pipe on their shoulders were firmly suppressed by the Japanese fire base and could not launch a strike.

"㘗㘗㘗......"

The three elongated whistles were still loud and clear, even on the battlefield under fire. At least the soldiers on the roof of the building who operated the gasoline cannons could hear it clearly.

"Test fire a shot and get ready to ...... Ignition. ”

Someone took a cigarette butt and lit the fire twist reserved on the front of the gasoline cylinder.

Strangely, there is a streamlined cover on the shells that are loaded into the gasoline canister. Not only that, but the periphery of the shell was made of curved bamboo slices with short wings that would automatically open when windward.

Maybe many people can't understand these things in this era, but for future people, these things are just basic common sense.

The fairing will reduce wind resistance, and the curved and symmetrical arrangement of bamboo pieces will allow the projectile to rotate and fly farther. As for some other tiny designs, the appearance of the gasoline cannon, which did not shoot, was not visible.

"Tom......"

Due to the large caliber, the sound of these shells when fired was rather muffled.

At least none of the servicemen on the battlefield heard the sound of such shells being fired.

Even more different from what has been recorded in history is that these huge cannonballs that fly out suddenly shoot tongues of fire from behind their butts in the air.

The bottom exhaust bomb, in World War II, especially at this time, was extremely backward China, that was a fantasy.

However, physics and chemistry are immutable truths in any time and space, and they are the only ones in this world that can be verified or falsified. As for the rest, it will change from time to time, from place to place, and from person to person.

For example, who would have thought that after 80 years, someone would dare to mention that Qin Hui would overturn the case, and some people who just like comics or those who like Japanese indecent culture will actually become traitors.

But no matter how ideas change, the theorems and formulas of physics and chemistry will not. Even if a new discovery can falsify a theorem of the past, it can still be proven or falsified.

This is the reason why the smartest people in the human race choose to believe in science.

It is also a really powerful country, playing mathematics, physics and chemistry, and as for the other summaries, it is enough to say that "backwardness will inevitably be beaten".

The addition of fairings and extended-range rockets to the shells of the gasoline barrel cannon greatly increased the range and controllability of this largely inaccurate weapon.

However, it still retains the characteristics of a gasoline cannon, which is that the shells fly slowly.

At this time, almost everyone on the battlefield had their eyes fixed on the large cannonball that was flying slowly through the sky and dragging tongues of fire.

Watch as it crosses the highest point of the parabola, then turns down.

At this time, people who know how to use a scope or telescope to divide the distance are silently reading its distance.

"Four hundred meters, it's unimaginable, this thing actually hit a distance of four hundred meters."

As mentioned earlier, this gasoline barrel cannon was not tested, so this time all the gasoline barrel cannons were test-fired. Therefore, there is more than one large, slow shell that flies by.

Watching the cannonballs fall from the skylight, some Japanese soldiers holding steel shields put their sharp-cornered shields on the ground and at the same time pulled away the two supporting wooden sticks behind them to support the shields.

Then he quickly covered his ears and opened his mouth wide.

All eyes were on the cannonball flying through the skylight, wondering what kind of violent explosion it would cause when it landed.

However, the result was destined to be disappointing, not only for the people in the Sixing warehouse, but also for the Japanese soldiers.

On the battlefield, except for the Japanese soldiers in the fire base, who were still pouring ammunition on the roof of the Sihang warehouse building, almost all other operations on the entire battlefield were stopped.

Including the soldiers in the warehouse of the four elements, they all wanted to see what kind of surprises the new gadgets that Chief Zhang played would bring to them.

It's a very emotional thing to think about such a large shell.

However, to everyone's disappointment, none of the cannonballs, which looked powerful and flew slowly through the skylight, exploded.

"Could it be a gas shell?"

"How is it possible, how is it possible for such a backward country in China to produce advanced poison gas shells. And did you see it smoking, how could a shell that didn't even smoke be a gas shell. ”

Not only were the Japanese soldiers whispering, but even the soldiers in the Sixing warehouse did not close their mouths, which were about to see the spectacular explosion and then cheered, and then they were unwilling to close at this time.

"What's going on, how can it not make a sound, could it be that there are charcoal bars in it, it can't be just a bluffing thing."

Xie Jinyuan, who was holding the binoculars, was also puzzled and lost, but he still found the only excuse for Zhang Sixing in his heart. That is, the big guy who threw it out, there must be a time bomb with charcoal bars.

yes, there are charcoal bars as a time bomb, why is it so special that no one has thought about it. If you think about it from this perspective, you can open up many new uses.

Including Lu Feizhang from the hole blown up by the shells on the first floor, he also saw this scene, and also found a reason in his heart for these shells that did not explode.

He thought:

When the public grain was handed over to the puppet township office, if it was mixed with a bag of explosives with smokeless charcoal sticks...... It's hard to think about.

It's a pity that I'm fighting devils now, and I don't know if I can use it.

But it didn't matter what they thought, the gunners who had escaped from the prisoner camp and the gunners of the gasoline barrel artillery team under the command of the gunners on the roof of the building received the next order.

The commander of the artillery team, who was holding Zhang Sixing's periscope observation scope in his hand, also tested the distance, and muttered that there were people around him who could write silently.

"The No. 1 medicine bag is about 80 meters, the No. 2 medicine bag is 120 meters, and the No. 3 medicine bag is ......"

This is a method of controlling the firing range of the mortar, and the firing range can be controlled relatively accurately by determining the amount of charge. It's a pity that Zhang Sixing maintained secrecy and did not allow the test firing of the gasoline cannon.

"No. 6 medicine pack, target enemy fire base, aiming, ignition ......"

The commander of the gasoline drum shell never thought that the artillery would one day also use the word "ignition".

With his order, someone went up and loaded the launcher-pill bag.

Then he took a bamboo tube filled with gunpowder and pierced the firing bag from the reserved hole, while blowing the cigarette butt in his hand.

People who love to smoke love this way of firing, and in order to ensure the launch, everyone is given three packs of cigarettes.

Then the guy who had just put the medicine bag in it picked up a large cannonball and stuffed it into the gasoline drum.

Looking at the Japanese fire base and the devil soldiers everywhere, the commander of the gasoline drum cannon suddenly thought:

This row of shells goes down, and I promise to blow them up and call them Mom, will Lao Tzu go down in history because of this row of shells?
