But in this era, the era of powerful gunpowder weapons, the strong city gate, under the fire is also vulnerable.

Except for an armored City, the whole wall is made of steel.

No matter how strong the metal gate is, what is connected with it is only a wall made of stone. No matter how strong the stone is, it can not stop the power of artillery explosion. There is only one end, which is mercilessly destroyed by the first army.

At the end of the stone road, under the shade of trees, several dark green figures stand upright. The picture in the helmet shows the situation on the fortress wall not far away.

With the focus function of the sensor, everything on the remote city wall is clearly displayed in the picture in the helmet.

Shaking the head, as well as the black muzzle, all no longer show that the enemy is ready to fight.

Next to him, the huge hammer tanks rumbled one by one. In the woods on both sides, there were also mobilizers and scythes.

In the ear of all kinds of voice, love gave the order.

"Calculate the coordinates, ask the fleet for two rounds of fixed-point bombing, and attack the whole line after bombing!"

"Yes

At the command, an officer left.

It is more than ten nautical miles away from the fleet, which is beyond the communication range. We must use high-power communication instruments to ensure smooth communication with the fleet.

The battle in the early morning had not yet begun, but the fleet moored on the sea took the lead.

Received a call from the front-line forces, the fleet in the first time to respond.

The Gunners and sightseers are on standby 24 hours in turn. As soon as the request for fire support arrives, the turrets on each warship turn slightly, and the black muzzle aims at the coordinates.

"Coordinates 320148, two volleys, release!"

"Bang! Bang

With a flash of fire on the sea, the silence of the morning was destroyed by the sound of artillery.

Gun tube vibration, flame spray, in the surging flames, countless shells flew into the sky, whistling at dawn.

The changes in the distant sea have long been discovered by many eyes of the closely watched fleet.

Before the sound of shelling, the fort echoed the alarm to avoid bombing.

The sound of "Ding Ling Ling" was rapid and harsh, which echoed continuously in the fortress.

As soon as the alarm bell rang, the garrison on the south wall suddenly dispersed in a mass of people. Even the cannons on the wall were ignored. They rushed down the city wall and entered the dark hole under the city.

When the last figure left the city wall, the distant sea suddenly sounded the "rumble" of artillery.

After a moment, the sky whistling suddenly appeared, from far and near, to the moment.

At that moment, the explosion broke out, and countless fireballs rose from the south wall.

"Boom! Boom

The violent explosion was incessant, the flames were surging, the powerful shock wave swept all around, and the "rumbling" explosion was deafening.

Countless mushroom clouds mixed with flames are rising on the wall, and the scattered gravel is sweeping around like bullets.

The southern city wall was immediately shrouded by gunfire, and even the forest outside was affected. Countless fireballs rose in the forest, and the shock wave shattered everything around. The high temperature made the trees burn up temporarily. In the sound of "creak creak", countless thick branches were broken and fell to the ground in piles.

In the "boom" of gunfire, the southern wall is suffering from bright.

"Boom!"

Violent explosions, such as deafening thunder, are roaring.

The earth is shaking. In the surging flames, a section of the city wall collapses and countless debris flies into the sky.

After two rounds of shelling, the bombing was over.

When the last fireball rose on the wall and disappeared in the burst, the southern wall gradually subsided.

The smoke of war shrouded the fortress. From a distance, on the south wall of the fortress, dust filled the sky one after another.

"Up the wall! Prepare to fight

No one knows how many people were killed in the bombing. As soon as the bombing was over, the soldiers hiding in the dark hole under the city left the "safe" place under the urging of the officers and climbed up the wall again like dying.

In the dense sound of footsteps, countless figures rushed to the city wall and their respective posts.

After a series of bombing, the city wall has become dilapidated, full of gaps and craters.

The cannons erected between the battlements also lost a lot. Although there are well preserved cannons, the number is not much.

When the top of the wall was full of figures again, the troops who were marching in the forest were close to the wall.

The hammer tanks on the stone road are less than two kilometers away from the city wall.

"Attack

Seeing that the war machines on the stone road were approaching fiercely, the defenders on the wall launched an attack.

"Bang! Bang

The fire spurted, and the sound of gunfire rang out from the wall.

The cannons on the wall opened fire.

There was a roar in the air above the forest.

"Boom! Boom

On both sides of the stone road, there was an explosion on the crown of the trees in the forest. In the roaring flames, the broken branches fell.

"Boom!"

A shell also landed on the stone road and exploded on the stone road tens of meters away from the first hammer tank.

In the "thunder" like explosion, when the rising fireball dispersed, a small crater appeared on the stone road.

The enemy launched an attack, and the front-line forces of the first regiment also launched a counterattack.

So big hammer tank, the black turret turns slightly, the muzzle of the black hole aims at the end of the stone road "city wall".

"Bang!"

The thick gun barrel suddenly shrinks, and the flame spurts. A sharp howl suddenly sounds over the dark stone road.

It's less than two kilometers away, and it's in a flash.

"Boom!"

After just one breath, there was an explosion on the wall.

Air waves, stones dancing, splashing stones, let the garrison on the city wall for a while.

"Bang!"

In the distance, as soon as the explosion on the city wall fell, the hammer tank opened fire again.
