"boom!"

"boom!"

"Bang, bang, bang!"

“—”

“—”

At this time, from the air defense identification circle of the Heima Fort ‘Wangyue Mountain-Jiciao Mountain’.

A 150mm anti-aircraft main gun powered by pure green crystal energy, a 65mm anti-aircraft gun driven by n5 gunpowder and white crystal mixed energy with 10 times the power of tnt, and two 30mm rapid-air fire guns driven by white crystal.

They caught fire one after another.

A series of transparent low-density air passages were produced in the air, and the sound explosion cloud trajectory line slid into the airspace.

However, because these four energy cannons are all indicated by crystal fire control radar, they manually adjust the azimuth angle of the artillery azimuth and elevation angle to control the artillery.

This ancient and primitive combination is used.

When capturing and hitting moving targets that exceed four times the speed of sound and manually calculate the future overlap between the ballistic and target trajectory, it is still impossible to catch it.

It is far inferior to those large forces with "tiger gangsters" and "huge fingers" and have the precise ability to strike targets with cannon killing.

The shells shot out fell one after another.

Only the two 30mm rapid-fire guns with initial speed of only six times the speed of sound, "the quality is not good enough to make up for quantity". With intensive shooting of 3 rounds per second, the projectile immediately hit the target accurately.

However, through this high-altitude ferocious beast that has not been captured by the telescope, it still has a smooth dive speed line that remains unchanged.

The attack effect is obviously very limited.

"Pull up, get on!"

"Adjust the angle, speed, speed, aim and then bang!"

"Increase the charging speed of crystal stone!"

"Bang, bang, bang!"

In the busyness of all kinds of yelling and horror, the sky and the earth were filled with indifferent mixed sounds.

There is an echo of the mountains after the cannon explodes.

There are smooth streamlined projectiles that squeeze the whistle of air along the way.

And the continuous shelling sound of rapid-fire cannons of 3 rounds per second,

However, there is no ferocious beast that dived from high altitude, which produces the sound of sonic bomb clouds during high-speed movement.

Actually, it's not none.

Instead, the sound waves generated were left far behind by this ferocious beast.

Not to mention reaching the ground.

At the top of Wangyue Mountain, Liu Jinghu, Liu Fengheng, Liu Penghuan and others saw this scene.

All were shocked.

Just in this shocking moment, the ferocious beast was less than 10 kilometers away from the earth.

And it is still accelerating.

It is visually estimated that it has reached five times the speed of sound.

If the rate remains unchanged, it will be less than 6 seconds.

Critical hit to the earth!

"How does it brake at such a fast speed?"

Liu Jinghu's confidant adviser Zhao Pu shouted in shock: "How does it brake!"

At this time, when I saw this scene, in the air defense identification circle of the "Wangyue Mountain-Jiciao Mountain", in addition to the two 30mm rapid-fire cannons powered by Baijing Energy, they were still vainly catching the shelling.

The 150mm anti-aircraft main gun powered by pure green crystal energy, and a 65mm anti-aircraft gun powered by mixed gunpowder and white crystal energy.

The attempt to continue aiming and chase the shooting has stopped.

On the 80-limit south wall of Heima Fort, 40 65mm caliber were arranged in a row, made of 300 years of pig iron wood, and made of all-nitrogen anionic salt n5-gunpowder as the emitter.

Because this n5 gunpowder has extremely powerful explosion power, it also has great damage to the tear and rifle of the metal cannon body.

So in addition to the gunpowder and white crystal hybrid energy-driven gun that is specially used to strike high-altitude targets and fires 65mm spindle-shaped tungsten armor-breaking bombs.

The other metal cannons are powered by crystal energy.

These 16 iron wood smelting cannons use more cost-effective and cheaper imported n5 gunpowder as driving energy.

The projectiles fired are streamlined projectiles made of iron wire spider silk, iron wood smelting powder, asbestos, and high-temperature resistant sols.

Six diamond blades are inlaid on the top to serve as the core of breaking through armor.

"Boom, boom, boom!"

At the northeast corner of the south city wall, there are 10 guns in the south city wall and 4 guns in the north city wall within the effective range.

Start shooting.

The initial velocity of this kind of artillery, solid armor-piercing projectile, is 6 times the speed of sound, filled with high explosive bombs and combustion solidified bombs, because the material of the shell can only hit the initial velocity of 4 times the speed of sound.

Moreover, during the violent expansion of gunpowder, the vibration of the cannon body will inevitably cause certain errors.

However, it still has a strong advantage in hitting low-altitude targets that cost 6 kilometers.

"boom!"

A burning solidification bomb accurately hit the target beast at a height of 5.63 kilometers.

A dazzling fireball exploded.

"good!"

The entire Wangyue Mountain air defense identification circle, the angle between the north and south city walls, and thousands of people in the nearby city shouted in unison.

As the shouts were heard, the ferocious beast continued to swoop in from the flames and the sonic bomb clouds!

"It's a dragon!"

"The dragon falling from the mountain north!"

"What's going on?"

"Are you crazy?"

At this time, as the distance from the ground was closer, the crowd of people in the Black Horse Castle below finally saw the face of the coming ferocious beast.

All of them were shocked and uproared.

You know, the actions of this giant dragon may have involved the huge tribe behind it.

"Does these evil dragons dominate Aurora?"

This thought can make people feel chilled all over and feel chilled.

"Stop the shelling, stop the shelling! Wang Dong, hurry, hurry, use the light source signal to tell Woguishan that you cannot attack, absolutely cannot attack!"

At this time, Zhao Pu was the first to react.

He shouted with a pale face at the top of his throat.

So everyone understood at this time.

This evil dragon must not be killed!

"Stop the shelling, stop the shelling!"

"Don't fry, don't fry!"

Suddenly, Yingyue Mountain shouted like a tide.

Amid the shouting, there were two 65mm hybrid rapid-fire cannons on the other hills and 14 65mm gunpowder power cannons on the north and south city walls.

Still shooting hard.

During this period, when the dragon quickly dived to an altitude of 4.5 kilometers above his head.

A straight, light green, round light.

About 15 miles away from Wangyue Mountain, the lonely peak of Heima Fortress lies on Guishan Mountain in the middle of the city, and suddenly shot out.

He instantly hit the evil dragon, then penetrated the sonic bomb cloud behind him, pointing straight to the blue sky.

"It's over!"

At this moment, looking at the top of the moon, there was a silence like death.

——

“10 km, 9.15, 7.6,—”

"Aim, aim!"
