Black smoke rose from the two damaged enemy aircraft, and the plane staggered in the air and lost control.

"Yaga !!"

The devil pilot was sweating profusely and trying to maneuver the plane that was falling.

Despite the best efforts of the devil pilots, they were unable to pull up the runaway plane.

"Don't, don't !!"

The devil pilot shouted in horror, and the enemy plane rolled left and right, falling to the ground quickly.

The enemy plane is less than 300 meters above the ground, and even if the devil's pilot parachutes, he will fall into meat sauce.

"Imperial pilots, attack !!"

The rest of the devil planes, as if they were crazy, ignored the anti-aircraft fire on the ground and flew in a swarm over the eastern position of the security regiment.

Dozens of enemy planes hovered in the air, all of their on-board machine guns were fired, and bullets were constantly pouring on the ground.

"Sudden !!"

"Da !!"

Noisy machine guns rang out in midair, and countless bullets were splattered on the forward positions of the security regiment.

Although the on-board machine guns of the little devils were intensive, the soldiers of the security regiment on the position were hidden in the trench bunkers, so the casualties of the soldiers of the security regiment on the position were not large.

Of course, the enemy's airborne machine guns are not the most terrifying, but the aerial bombs carried by enemy planes are the most terrifying weapons of destruction.

"Buzz—"

Dozens of fighters and bombers hovered over the positions of the security regiments, and the devil pilots brutally threw down a large number of aerial bombs.

"Damn Shina soldiers, die!!"

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

Dozens of bombs swayed down from the air, emitting a terrifying scream of breaches.

Like a meteorite, the bombs continued to bombard the ground, shaking the ground and shaking the mountains one after another.

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

The bombs exploded one after another, blowing up a large huge crater, and the powerful shock wave swept the mud and sand to a height of more than ten meters.

The explosive power and lethality of the aerial bombs are not at all comparable to ordinary artillery shells, and the explosion of so many aerial bombs is as terrifying as if it is about to destroy the world.

Even though there were a large number of little devil planes, the soldiers of the air defense unit of the security regiment still stuck to their positions and stubbornly resisted the devil's planes.

"Brothers, hold your ground and take out the devil's plane!!"

The soldiers of the security regiment, ignoring the bombs and bullets of the devils, desperately hit the enemy plane flying in the air.

"Da !!"

"Tom !!"

Bullets and shells greeted the devil plane in the air, and the engines of several enemy planes were all damaged, and the devil pilot quickly pushed open the hatch and parachuted to escape.

"Bagaya Road, kill the air defense positions of the Chinese soldiers!!"

The little devil became savage and crazy, and his behavior was also very terrible, just like a devil who didn't want to die.

Several bombers dived and opened fire, rushing towards the air defense positions of the security regiment, and the devil pilots tried to die with the air defense units of the security regiment on the ground.

The rushing devil plane quickly made an evasive maneuver and dodged some shells and bullets, but the fuselage was still scarred by bullets.

The devil planes were damaged, and some were out of balance.

Once the enemy aircraft is damaged, its maneuverability and agility will be reduced, and it will be easily shot down by ground anti-aircraft fire.

At the risk of being shot down, the devil pilots threw bombs at the anti-aircraft positions of the security regiment.

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

Several aerial bombs fell near an anti-aircraft fire position on the ground of the security regiment, and the flames of the explosion engulfed the position.

There is no problem with the fortifications of the bunkers on the air defense positions to defend against machine gun bullets, but it is not so easy to defend against the bombardment of aerial bombs.

With the bombardment of aerial bombs one after another, the air defense fortifications on the position were seriously damaged, the breastwork was destroyed and collapsed, and dozens of sandbags were splashed all over the sky and became sparse.

"Uh, uh, uh......"

More than a dozen soldiers on the air defense position were blown out of their bunkers by aerial bombs, and each soldier's body was blurred with blood, and blood was splattered everywhere.

The soldiers of the Security Corps, who were killed and wounded by aerial bombs, fell under the fortifications screaming in pain.

In addition to the casualties among the soldiers, anti-aircraft weapons were destroyed by aerial bombs, and parts of anti-aircraft guns were everywhere.

The devil pilots seized the opportunity, and several bombers bombed back and forth over the air defense positions.

The bombs exploded one after another, and the shock waves and flames released by the bombs consumed all the living objects around them.

In the blink of an eye, the air defense position of the security regiment was completely blown into a scorched earth by the little devil plane, and the position was full of sacrificed machine gunners and artillerymen.

Although there are many anti-aircraft fire positions outside the city, the number of planes of the little devils is too large, and the enemy is outnumbered, so it is really difficult to resist the air attack of the devils......

Li Hong stood on the building floor in the city, looking at the group of devil planes outside the city from a distance, and couldn't help frowning.

If the bombers continue to bomb, the air defense positions outside the city will be destroyed by enemy planes, and the soldiers guarding the front-line positions will also pay huge casualties.

Li Hong knew that the security regiment was insufficient, and let the brothers on the front line resist the devil's aircraft and artillery, which would only increase casualties.

If the security regiment suffers heavy casualties, there will be an empty force, then the positional defense will also become very weak, and the enemy will be able to break through easily.

The enemy planes did not care about the losses, and moreover, they spent a lot of ammunition to bomb the positions outside the city, and the little devils, in addition to taking revenge on the security regiment, mainly wanted to take the positions as soon as possible.

The devil's reconnaissance plane had reconnoitred the situation in Xuzhou before, and the devil's commander knew that a large number of air defense positions had been arranged in the city, so the enemy planes did not dare to bomb Xuzhou City easily.

In fact, the most powerful thing for the little devils is artillery, and the enemy has all kinds of large-caliber artillery.

As long as the position outside the city is lost, then the little devil heavy artillery can move forward, and the artillery fire can directly threaten the defenders inside the city.

After observing the battle situation outside the city for a while, Li Hong called the communication soldiers.

"Signal soldier, order the air defense forces in the east of the city to open fire and give Lao Tzu a hard blow to the enemy planes outside the city!!"

"Yes, Tuanza!"

Receiving the order, the signal corps immediately picked up the phone and called the air defense units in the east of the city.

The air defense forces in the east of the city arranged seven or eight anti-aircraft guns on the tower in the east of the city.

Until the situation on the battlefield is grim and as a last resort, Li Hong will not expose the position of the anti-aircraft fire in the city at all.

However, there are too many enemy planes outside the city, and the bomb fire is fierce, and if the anti-aircraft guns inside the city do not provide support, I am afraid that the position will really be razed to the ground by enemy planes.

After the air defense units in the east of the city received the order, the artillerymen entered the artillery positions one after another, the artillerymen uncovered the camouflage of the anti-aircraft guns, and immediately, the ammunition men brought a large number of shells and put them on the positions.
