After the explosion of the colliding enemy plane, the walls of the city were in ruins, and the castle corridors were littered with broken walls and debris of the explosion that burned with flames.

The explosion caused by the collision of the devil's plane just now was no less powerful than the explosion of several aerial bombs.

After a few minutes, the defenders of the city shook their drowsy heads, then pounced on the ruins of the city walls, and climbed up from the ground with difficulty.

"Brothers, get back to the fighting position!!"

"Medic, come here, there are wounded !!"

The soldiers of the security regiment returned to their positions, and the medics and stretcher teams ran back and forth on the towers to treat the wounded.

There were also some soldiers carrying sandbags and tools in their hands, and hurried to repair the collapsed and damaged city walls.

The number of enemy planes outside the city gradually decreased, and the devil planes were hit by the anti-aircraft fire of the security regiment, and the enemy planes either crashed or were damaged.

In the end, seven or eight devil planes fled over the battlefield with scars and messes.

The two divisions of the devil dispatched a large number of planes to help the battle this time.

After the first echelon of the devils was defeated and evacuated, suddenly, a large flight formation swarmed in the north direction of Xuzhou City.

"Buzz—"

The sound of the plane's engine was deafening, and dozens of enemy planes sailed through the clouds, quickly approaching Xuzhou City.

This time, the devil pilot received a death order to bomb Xuzhou City at all costs.

With the help of the cover of the clouds, the air defense units on the ground of the security regiment only heard the sound of the plane's engine, and they could not see where the devil's plane was at all.

In a blink of an eye, the devil group broke free of the clouds and flew over Xuzhou, and then, the devil bombers and fighters lowered their flight altitude.

The Devil Group did not carry out fire reconnaissance in the city, and dozens of enemy planes launched a collective attack, reducing to an altitude of about 1,500 meters in the fastest time, and were ready to attack the ground.

"Imperial soldiers, prepare to throw aerial bombs and destroy the city of Xuzhou!!"

Under the order of the devil flight commander, the devil pilots began to throw aerial bombs one after another.

Aerial bombs fell from the devil bomber in pieces like scattering beans.

"Hurricane, hurricane, hurricane......"

"Hurricane, hurricane, hurricane......"

A large number of bombs tore through the air, and a whistling sound erupted.

More than 100 aerial bombs swayed down from the air and smashed into all corners of the city, and the ground continued to burst into dazzling and blazing fires.

"Boom, boom, boom!!"

"Boom, boom, boom!!"

The explosions in the city came and went, and the aerial bombs exploded in all directions, and suddenly, the city was filled with firelight and smoke.

The bombing points of the devil bomber group were mainly concentrated on the streets in the north of the city, and a large number of houses on the side of the streets were crumbling and collapsing one after another under the destruction of aerial bombs, and bricks and rubble were flying everywhere.

The devil pilot didn't see the target clearly at all, and it was just a wanton bombardment.

"Buzz—"

The devil's group hovered in the air, continuously pouring aerial bombs, many buildings on the ground were destroyed by aerial bombs, and nearly 100 houses collapsed and became ruins.

Don't look at the little devil's plane, the bombing was very fierce, destroying many buildings and civilian houses, but the soldiers and civilians in the city were hidden in the air defense fortifications, and there were not many casualties.

Buildings in various streets in the north of the city were seriously damaged by aerial bombs, and more than half of the houses were destroyed.

Not only that, but the devil's bombers began to drop incendiary bombs.

"Hurricane, hurricane, hurricane......"

"Boom, boom, boom......"

The sound of explosions and the screams of falling bombs resounded throughout the city.

As a large number of incendiary bombs fell, many streets in the city were set on fire, and buildings were ablaze.

"Damn, the little devil plane is too deceitful!"

Li Hong stood on the building floor, holding an M2 Gaoping dual-purpose heavy machine gun, and opened fire on the whistling enemy planes.

"Sudden !!"

The dense bullets flew head-on to the enemy plane thousands of kilometers away, and the devil pilot was caught off guard by the bullets and died several times in the cabin.

The out-of-control planes crashed into the buildings in the city, and the planes exploded and caught fire, destroying several houses.

As soon as Li Hong opened fire on the enemy plane, the air defense unit of the security regiment in the city also aimed at the devil bomber overhead.

"Tom !!"

"Boom, boom, boom!!"

Anti-aircraft guns and anti-aircraft machine guns in the city opened fire together, and large areas of bullets and shells flew out from all corners of the city.

The four or five enemy planes flying in front were hit by the anti-aircraft fire of the security regiment, the fuselage was burning with flames, and the planes dragged black smoke and fell to the ground.

"Yaga, pull up the !!"

The devil pilots saw that the plane was out of control and kept falling, and they pulled the control stick hard, but no matter how the devil pulled the plane up, it had no effect, and the fuselage kept falling.

The devil pilot was about to burst out of his feces and urine, so he had to push open the cockpit and escape from the cabin with his parachute bags on his back.

Several devil pilots jumped out of the plane, quickly opened the parachute, and soon, several planes crashed to the ground.

In fact, whether the little devil parachutes or not, the result is a dead end, and skydiving is nothing more than being able to survive for a few more seconds.

Li Hong and the soldiers in the city, when they saw the little devil pilot parachuting, immediately moved the heavy machine gun in their hands and ruthlessly strafed the little devil who landed in mid-air.

"Tutu Tu Tu Tu—"

"Da Da Da-"

More than a dozen anti-aircraft machine guns fired together, bullets flew out of the corners of the city, and every little devil who jumped into the sky was killed by a large number of bullets.

"Ahh......h

The devil pilot screamed in mid-air, and the devil was beaten into a hornet's nest by bullets, and the blood splattered on the parachute.

The parachute was riddled with bullets, the devil pilot fell like a sack from the air to the ground building, and the corpses of the enemy were shattered.

The little devil pilots bombed the city so desperately, in order to put pressure on the defenders in the city, and then the devil's army launched a fierce attack from the weak point outside the city.

The trick of the little devil really worked wonders, the security regiment did not have many troops in the city, and it was really difficult to deal with so many devils.

Taking advantage of this opportunity, the Devil Heavy Artillery unit outside the city moved forward its artillery positions and launched artillery bombardments in three directions: east, south, and north of the city.

"Tom !!"

"Tom !!"

"Tom !!"

Dense shells flew out of the devil's position and flew like a sea of mountains towards the position of the security regiment outside the city.

The 9th Division of the Devils assembled a wing to attack head-on from the east of the city, and the 14th Division sent a wing to attack from the north and south of the city at the same time.

The devil's heavy artillery fire was very ferocious, and the artillery fire covered the defenders of the security regiment, and the suppressed soldiers could not fight back at all.
