At about 9 o'clock in the morning of February 16, 316 A.D., 60 I-153 fighters that had attacked the Imperial Army airfield returned home, and the surrounding ground crews immediately rushed up to refuel and load ammunition for the returning fighters.

After more than an hour of busyness, the group of planes that had returned was started again, took off from the airfield in a queue and flew to the airfield of the Imperial Army again, this time the group was replaced with a powerful 40-kilogram aerial bomb, and it was about to bomb the oil depot and ammunition depot of the Imperial Army airfield for the second time, so that even if the Imperial Army replenished the lost fighters in the future, it would not be able to take off into the air without fuel and ammunition, and a large amount of fuel and ammunition could not be replenished in a short time.

Before 16 February, Ouyang Yujun's camel fighters were dispatched every day to reconnoiter the deployment of the Fifth Front Army at high altitudes, where it was possible to be a material warehouse, where it was possible to be an ammunition storage point, and where was the command headquarters.

In addition to the sixty fighters that attacked the airfield of the Imperial Army, Ouyang Yu divided the remaining sixty I-153 fighters into five squadrons, and then ordered the I-153 fighters of these five formations to fly towards important strategic targets after eliminating the large-caliber magic crystal artillery group of the Fifth Front Army, as well as the headquarters of the Front Army and the headquarters of various group armies.

Forty kilometers northwest of Norin City, this is an ammunition storage point for the Fifth Front, where mountains of various types of magic crystal shells are stored, and there is also a battalion of troops guarding, and the entry and exit checks are very strict, even if Grand Duke Philip comes without a pass, he cannot enter.

At 9:44 a.m., twelve I-153 fighters of the third squadron of the Ouyang Yu Army Air Force flew to the ammunition storage point, and this time the I-153 fighters of the third squadron did not dare to dive, in case of a large explosion of the magic crystal shell inside, the bomb-dropping I-153 fighters would definitely be involved in the explosion, so horizontal bombing was used in the air of one thousand meters.

The 12 I-153 fighters of the 3rd Squadron were in an inverted V-shaped formation with relatively neat intervals at a distance of 1,000 meters, and the four incendiary bombs mounted under the wings were dropped at a distance of one every 100 meters.

The battalion in charge of the guard did not expect that the enemy would attack from the air, and by the time they reacted, the ammunition storage point had already ignited a sky-high fire, and the fire formed by the gasoline incendiary bombs was very large, and the burning gasoline would flow around to form a larger overfire area, and the gasoline burning water could not be extinguished, so the fire fighting behavior of the guard battalion was doomed to be futile.

"Boom...... Boom......!"

In the heat of the fire, some munitions began to detonate, and then a larger chain reaction was triggered.

"Boom......!"

An earth-shattering bang suddenly sounded, and the chain explosion of ammunition at the storage point leveled everything in the surrounding five kilometers, and the shock wave of the explosion even shook the fighters of the 3rd Squadron, which had already flown out of the distance, and the battalion guarding the storage point, including the battalion commander, was all blown up and there were no bones left.

At 9:51 a.m., twelve I-153 fighters of the 1st Squadron appeared over a warehouse of the Imperial Army, where 10 tons of grain and 50,000 winter coats of the Fifth Front were stored. Twelve I-153 fighters of the first squadron quickly assigned their respective tasks and then began to reduce altitude.

The defenders below found that the fighters of the first squadron were in a mess after the attack, some ran into the warehouse to rescue the contents inside, some raised their guns to shoot at the air to shoot down the incoming enemy planes, and more of them stood still and did not know what to do, because the soldiers of the Imperial Army had never received air defense training.

"Dadada......!"

The first three I-153 fighters began to strafe the ground, killing and wounding and dispersing some of the Imperial soldiers who were shooting in the air with magic crystal rifles, and then the nine I-153 fighters behind locked on to their respective targets and dropped thirty-six incendiary bombs, more than ten wooden warehouses were burned in an instant, and the first squadron did not leave immediately after completing the arson mission, twelve I-153 fighters turned in the air, and the nose of the nose repeatedly strafed the defenders of the warehouse below, so as not to let the Imperial soldiers below go to put out the fire, and after ten minutes, the bullets were almost consumed, and the things in the warehouse were almost burned, only to swing the wings and leave contentedly.

At 10:01 a.m., the 233rd Regiment of the Fifth Front Army was stationed, and the 233rd Regiment had been waiting for orders in the camp because it had not received the order to start the offensive for a long time, and more than 1,000 soldiers had already assembled and lined up in a neat queue to wait for departure.

"Buzz....... ”

Hearing the roar of the plane, some soldiers of the Imperial Army couldn't help but look up in the direction where the sound came from, because the headquarters of the Fifth Front Army and its subordinate group armies were bombed, and the command of the Fifth Front Army had fallen into chaos, and the news of Ouyang Yu's army launching an air raid did not spread to all the troops, and many troops who did not receive the news of the attack to cancel the air raid were like the 233rd Regiment waiting in line for an offensive order that would never come.

"Huh, why are our fighters going to dive towards us?"

Lieutenant Colonel Henry, the commander of the 233rd Regiment, thought strangely in his heart, he thought that this was just a prank by the air force pilots, but when the I-153 fighters of the second squadron of Ouyang Yu's army began to strafe, he suddenly realized that these fighters turned out to be the enemy's, and when he ordered the evacuation, it was too late, and the twelve I-153 fighters had already begun to wash the ground with rockets.

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

There was nothing better than a live target for the soldiers of the Imperial Army in a dense queue, the powerful 12.7mm bullets in the dense queue, a single bullet could penetrate three or four people, and the twelve I-153 fighters strafed and rocketed left behind three or four hundred broken corpses, but this was the beginning of the nightmare.

At 10:53 a.m. at the temporary airport of the Imperial Army, Brigadier General Würth was directing a large number of ground crews to rescue the wounded and extinguish the fire, especially rescuing pilots is a priority, every pilot has spent a lot of money to train, and it feels very distressed to die a Brigadier General Würth, not to mention that more than 60 were killed in an air raid not long ago, as for the plane, Brigadier General Würth is not distressed, the Phoenix Empire itself is very rich, plus the looting of the occupied areas in the past few decades is even richer, and it will not take long for the destroyed fighters to be replenished or even more。

Thousands of ground crews and soldiers protecting the airport fought together to save the still burning warplanes, and the hundreds of wounded were concentrated in the residential area because there were too many wounded, and several military doctors and a dozen nurses were too busy to touch the ground, but the busy scene was quickly replaced by fear.

"Enemy planes, enemy planes!"

Sixty I-153 fighters reappeared in the eastern sky, and the Imperial soldiers on the airfield did not care about putting out the fire, leaving their tools and fleeing in all directions.

The sixty I-153 fighters of the second wave were also divided into five squadrons, and after flying over the Imperial airfield, the five squadrons launched attacks according to their respective tasks.

"Uh......h Dada...... Boom, boom, boom......!"

The 6th and 7th squadrons were loaded with high-explosive bombs aimed at anti-personnel personnel, and twenty-four I-153 fighters scattered to chase the fleeing Imperial soldiers, either strafing at low altitudes or dropping bombs, and the airfield of the Imperial Army instantly turned into a Shura hell.

The 8th, 9th and 10th squadrons flew to the fuel depot and ammunition depot and the personnel quarters, respectively, and the three squadrons were still carrying incendiary bombs.

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

Three dragons rose at the airport, a high concentration of magic crystals ignited, and the ammunition depot exploded, killing hundreds of wounded people in the populated area, along with the doctors and nurses who treated them.

Ouyang Yu's air raid operation began as soon as the sun rose in the morning and continued until the sun set, and the Fifth Front Army suffered huge losses and directly lost the ability to attack.
