The air has a natural advantage over the ground. In World War II, the German army relied on the good coordination between the ground and the air to form a rapid assault capability.

Many people like to talk about the German blitzkrieg, but in fact the blitzkrieg is not about the armored spearhead, but about the extremely powerful air power of Germany.

In particular, the Stuka dive bomber, which was described as being able to throw bombs into a saucepan, was one of the reasons for Germany's rapid progress in the early days of the war.

In the twentieth world, whoever masters the sky will master the world.

Zhang Sixing has long been sure of this, but now, how can he, who is on the disadvantaged side, solve this trouble.

"Kites, put all the kites up for Lao Tzu, don't bring bombs on them, just kites will be."

Kite flying?

Everyone on the roof looked at each other, not understanding what he was trying to do.

In fact, it's nothing, the kite is flying in the sky, so the height of the plane flying over the four rows of warehouses will inevitably be higher than the kite. Then increase the height by a few tens of meters, and the hit rate will decrease.

It's like those hydrogen balloons released for air defense on the battlefields of Europe.

Because of the speed of the plane, don't look at the kite string, but no pilot with a brain will fly the plane inside. Although kites are certainly not as good as hydrogen balloons, they are not as large as the number of them.

Sure enough, when the kite flew into the sky, because there was no bomb hanging, no matter the south wind and the north wind, the kite was put high on it.

Although it may not be of much use, it has an extra layer of cover and makes some trouble for the pilot.

But Zhang Sixing will not only defend but not attack, he thinks about the weapon at hand, and finally has some ideas.

"Go to someone, get one for our gasoline barrel cannon, and get a few steel helmet mines."

When I was in the air raid just now, I felt that I didn't need that thing, so I let people go back to the building.

"Facing north, don't make the bottom too thick, try to ...... to the sky"

Seeing Zhang Sixing's behavior, everyone who saw it didn't know why.

Cao Zijin came to the busy Zhang Sixing, and from time to time looked at the enemy planes in the sky that were adjusting their direction, and he asked tentatively,

"Sir, you don't expect this thing to jerk off."

On the shelving plane, this thing can collapse five kilograms of bomb powder for 300 meters, so how high can the steel helmet mine collapse?

was holding a somewhat smelly steel helmet thunder, Zhang Sixing looked at it and said nothing. But Lu Feizhang said,

"It doesn't matter if you try it, why doesn't the shrapnel of the steel helmet mine fly dozens of meters. If you can't get off the plane, you can spray it with a lot of feces and relieve your anger......"

"This is just nonsense......

However, Cao Zijin didn't dare to say this, and yesterday he saw this earthy gasoline cylinder spraying out the explosives bag far away, and the power was like a special heavy artillery.

It may not be the best weapon against fighters, but at this time there is almost no air defense, it is impossible to try everything.

Originally, this thing fired an explosive-charge-pack that burned the lead-fire-cable, so how would the grenade in the steel helmet mine explode?

Remove the gasoline cannon, the conical fairing, and remove the explosives that were tied into cubes. I tried the steel helmet mine and was able to put it in, but I didn't know how to pull the strings of the grenade.

At this time, Cao Zijin, who had been observing the fighters in the air, saw the Japanese fighters in the sky that had been lined up, and he pointed to the sky and shouted,

"Sir, I'm afraid it's too late, otherwise let's shoot with a gun."

In the blink of an eye, I saw Zhang Sixing take a nail, separate the fire and projectile in the gasoline barrel cannon, wrap a nail in the wooden board that was torn to ensure that the breath is closed, and then tie the grenade string to it.

He put the streamlined warhead back into the gasoline barrel cannon, and glanced at the fire twist sticking out from under the gasoline barrel cannon, and he commanded,

"Listen to my orders to light the fire."

Obviously, the Japanese planes that attacked from the south the previous time had to turn into an east-west attack.

Not because of anything else, but because of the kites that were released to about a hundred meters in the sky with the morning breeze. After all, a high-speed plane can be knocked down by a single bird, let alone those kites.

"Using kites to block planes, it's a shame that these people can think of it."

"They can't build anything, they can't build planes, tanks, and of course they can't build hydrogen balloons."

There were journalists from various countries on the airship, and there was certainly no shortage of Japanese reporters in it. But more Chinese reporters, hearing one or two Japanese reporters say this, someone has already replied with a sneer,

"A kite played by our ancestors is enough, so why bother with a hydrogen balloon. It's just that I didn't expect that the things of the ancestors can be played and fought at the same time. ”

No matter how the people on the news airship scolded each other, at this time, holding a sniper-rifle, Zhang Sixing, who still determined the distance from the dense position on it, silently calculated:

The grenade explodes five to six seconds after pulling the string...... The fuse-fuse for firing is about two inches, and the firing time after ignition is ......

"Woo......"

As usual, the two fighters took the lead and swooped down as if they were about to strafe.

This time, the people on the roof of the Sixing warehouse were much more prepared, because Cao Zijin was born in the regular army and had been educated in anti-aircraft shooting, so Zhang Sixing asked him to command.

At this time, the person with a light machine gun had a "human gun mount" in front of him. Someone held the two legs of a light machine gun, and someone carried a light machine gun directly on their shoulders.

At such a close distance, the ears may be deaf by the sound of gunfire, but no one cares about these things when it is fatal.

As the plane's engine grew louder and louder, everyone on the roof of the four-row warehouse tensed their muscles. One by one, they stared at the plane, and put all their bodies and minds on the outside.

"Hit"

As Cao Zicao shouted, both machine guns and rifles rang out at the same time.

But this kind of firepower is still very weak for fighters in the sky. They only need to swing the joystick slightly under the dive, so that the plane will fly out of the serpentine path when it dives down, which will greatly reduce the risk of being shot.

Not to mention these light machine guns and rifle fire, even in the face of the dense anti-aircraft guns on the battleship, such a dive has a high probability of completing the dive safely.

Finally the bazooka fired, dragging the feathered wake of fire-arrow-catapult into the sky.

One kilogram after another, the bullets exploded in the sky, but the shrapnel with no shrapnel created a dangerous turbulence.

"Hmph, stupid Shina, you can't take down the plane with such a weapon."

The Japanese reporters on the news airship began to taunt.

However, before his words fell, there was a sudden sound of "Peng" on the top of the Sixing warehouse.

A large warhead burst into the sky, and with it flew a plank. But it didn't take long for the board to fall due to resistance.

I saw that the slow warhead flew straight towards the two dive fighters.

That...... What is that......

Of course, no one knows this guy, and this thing has only been seen in front of the world since the first battle last night.
