Just as the defenders of Redan City were engaged in a final battle to the death, the air force advance team sent by Linda happened to arrive in time.

This advance team consisted of 2 squadrons of fighters, 2 squadrons of large bombers and 2 squadrons of dive bombers, a total of more than 100 fighters. The fighters are different from the propeller fighters equipped by the Blue Star Army before, and these 48 new fighters are all newly developed jet fighters that have just been installed in the army, which are the prototypes that Linda and Tang Long tested and flew at the beginning.

This jet fighter equipped by the Blue Star Army for the first time was named F-1, and the power plant was two turbojet engines, with spiritual equipment such as the Floating Circle, and the top speed could reach an astonishing 700 kilometers per hour, which has exceeded the speed of most Dan Realm monks, and it is not even weak compared to some early Infant Realm monks. At the same time, because it is also equipped with a magic circle spirit tool, its mobility and flexibility are not weak compared to ordinary monks.

The fuselage of the fighter has a total of 5 plug-ins, 4 of which can be used to mount weapons, and generally carries four 16-cell spell rockets. This kind of rocket loaded with precision spells and dexterity can automatically aim at the target like a missile, and the range is also five or six kilometers away, and the attack power is equivalent to the full force of the monk in the late stage of the realm, which can be said to be the main battle weapon of the F-1 fighter. In addition, the fighter was armed with two 25-mm guns with a rate of fire of 123 rounds per minute. The fuselage is also equipped with a protective spirit equipment that can release a protective shield, which can release various spells. The F-1 fighter, which is composed of a combination of various advanced weapons, can be compared to the early stage monks of the Dan Realm.

The 48 bombers of the advance team are also new models, this new bomber numbered H-2, although it still uses propeller engines, but it also flies at a speed of more than 400 kilometers per hour, can carry more than 2 tons of weapons, from all kinds of ordinary bombs to some long-range large attack weapons can be carried, and the body is also equipped with protective spirit equipment, and the attack and defense capabilities are extremely strong.

The other two dive bomber formations of the advance team were improved "vulture" dive bombers. This kind of fighter once shined in the battle of Changshan City, and posed a great threat to the ground forces of the Qin army at that time. And this batch of improved "Vulture" fighters has been improved in terms of flight speed, flexibility, endurance and attack weapons, and can also be equipped with heavy attack weapons, which is a sharp weapon for the Blue Star Army's ground attack.

Under Linda's order, this group of air task forces belonging to the Prairie Front and deployed at an important base 200 kilometers away from Ruidan City immediately took off after receiving the order and drove towards Ruidan City at full speed.

In order to prevent the Qin army's spiritual sense reconnaissance, the fighter only used mechanical power along the way, and did not use the mana of the onboard spirit equipment, so although the formation was large, the roar in the air could be heard several kilometers away, but it thus concealed the long-distance reconnaissance of the Qin army's spiritual sense. At this time, after more than half an hour of advancing at full speed, the formation was already less than twenty kilometers away from Ruidan City, and the formation commander Hui De could already clearly sense the battle situation in Ruidan City ahead with his spiritual sense.

"Sir, I just received a distress signal from the ground forces, and General Shen's headquarters has been forced to the last position and is surrounded by the Qin army on all sides. Commander Linda wants us to go to support immediately, do you need to start the spiritual support and speed up?" A communications officer in a modified H-2 bomber asked Hui De on the command platform.

Hui De shook his head and said, "No, although the speed of activating the spiritual power assistance can be faster, it will also be discovered by the Qin army's spiritual sense immediately, and the effect of our surprise attack will not be achieved." The formation was ordered to reduce the flight altitude and approach the target at low altitude. In addition, send the information on the location of the enemy troops transmitted by the ground forces to each formation, so that everyone is ready for battle!"

Soon, more than 100 fighters of the air contingent descended from an altitude of several thousand meters to more than 100 meters above the ground, and the group of planes roared, like a prehistoric flying dragon, slashing through the fan-shaped air flow on the ground and flying quickly towards Ruidan City.

King Qin sat on a giant finger battle platform pulled by four huge spirit beasts, looking at the front line in the distance a little impatiently. Seeing rows of cavalry fighting in front of the opponent's defensive line, but still unable to capture the last position of the Blue Star Army, his face was quite impatient.

Suddenly, he jerked up from his seat, staring strangely in a certain direction in the distance.

"What's going on? In that direction, something seems to have suddenly appeared?!? how can it be so fast, even faster than the Dan Realm monk... This is impossible!How can there be so many Dan Realm cultivators in the Blue Star Country?!" King Qin muttered to himself, an expression of disbelief on his face.

Seeing King Qin's expression, the surrounding Qin soldiers hurriedly used their spiritual sense to probe in the direction that King Qin had noticed, but the strange thing was that except for an infant realm general who seemed to be aware of it, the others didn't notice anything.

As if to verify King Qin's doubts, a group of black dots suddenly appeared from the eastern sky, and the black dots changed from small to large, approaching the battlefield at an alarming speed, and soon flew over the battlefield.

I saw dozens of things like big birds roaring towards the thousand-strong battle groups of the Qin army that were charging, dropping iron bump-like things in mid-air, and the Qin soldiers below didn't have time to react, and immediately more than a dozen battle groups were hit, sending out an earth-shattering explosion.

In King Qin's surprised gaze, most of the more than ten battle groups that were hit immediately lost their combat effectiveness. Some of the falling iron bumps exploded, while others turned into huge fire dragons or yellow sand, rolling towards the Qin army's charging troops, drowning groups of Qin soldiers who had no battle array to protect them.

What surprised him even more was that dozens of larger things were drilled out of the sky, constantly throwing things downward, although the accuracy was a little worse, but there were more and more powerful. Some of the things that were dropped were obviously some kind of spells, and they automatically exploded in the air, converging into a fire dragon and rushing towards the Qin army. Some fell to the ground, conjuring up fire pythons, ice pythons, and earth pythons, and pounced towards the Qin army battle groups with different restraint attributes. The more than 300,000 Qin troops who were attacking, because they were too dense in a group, had no time to dodge, and after receiving such a fierce attack, tens of thousands of people were killed and wounded in an instant, and the Qin army's attack on Shen Hao's troops was also slowed down.

"Are those things the planes of the Blue Star Country? Sure enough, as Wuhuan said, it is indeed a bit powerful, it seems that the reinforcements of the Blue Star Army have really arrived. However, it came at the right time, taking this opportunity to annihilate the main force of the Blue Star Army in one fell swoop. Order the Flying Beast Legion to attack immediately and take down these pesky mosquitoes for me!Also, let Montaigne and Li Kuo prepare for battle, the reinforcements of the Blue Star Army will arrive soon, let the widow meet them well, hehe..."

King Qin was not annoyed by the appearance of the Blue Star Army fighter, he thought about it for a while, and immediately made a new battle order. And the Qin army was also worthy of being experienced in a hundred battles, and received this fierce head-on blow, although it suffered a lot of losses, but it immediately gained a firm foothold and launched a new attack. The large wargroup that had originally charged ahead immediately dispersed to avoid the fighters in the air, while the Flying Beast Legion of the Qin Army immediately launched an attack on the Blue Star Army Air Force.

The main force of the Qin Army's Flying Beast Legion was the Demon Crow Sky Horse, and after seeing the Blue Star Army fighter plane that suddenly appeared, under the leadership of an infant realm general, the Flying Beast Legion immediately divided more than 3,000 Demon Crow Sky Cavalry to pounce on the fighter.

The flight speed of these demon crows is not slow, comparable to that of ordinary Dan Realm monks, reaching about 3 or 4 hundred kilometers per hour, but the number occupies an absolute advantage, but compared to the Blue Star Army F-1 fighters, it is still a step behind.

The Blue Star Army's reaction was not slow, and seeing more than 3,000 crows rushing in densely, Commander Huide immediately ordered the bomber formation to return immediately. He had long known that the Qin army's air power had an absolute superiority in numbers, and of course he would not be stupid enough to use his more than 48 fighters to fight the thousands of demon crows of the Qin army. Therefore, as soon as the bombers appeared, he ordered a fierce attack, and the thousands of bombs of various types carried by the four bomber formations were all launched in one go, and all the brains were poured into the heads of the Qin army, and then he immediately ordered the bombers to return, leaving only the fighter formation to meet the Qin army.

Huide did not want to fight a decisive battle with the Qin army in the air, but hoped to attract a part of the Qin army's air power transfer to relieve the pressure on Shen Hao's troops on the ground. After seeing more than 3,000 crows flying, Hui De deliberately let the fighter formation circle around the same place several times and shot down some crows. And the Qin army's demon crows not only couldn't catch up, but the attacks of magic weapons and spells couldn't reach, and the Qin army infant realm commander led by him was furious, leading the troops to pursue the fighter plane, and this chase and escape, actually flew out dozens of kilometers away in one go.

"Withdraw immediately!" Shen Hao gritted his teeth and ordered decisively.

The attack of the air force advance team just now dealt a powerful blow to the ground forces of the Qin army, and its offensive against Shen Hao's troops was also slowed down, and finally the pressure on Shen Hao's troops was temporarily relaxed. Seeing this opportunity, Shen Hao immediately ordered the remaining defenders to withdraw from their positions and quickly move to the eastern rear.

At this time, the three group armies led by Shen Hao fought from more than 300,000 people at the beginning to only more than 100,000 people, and after the retreat order was issued, the rear army immediately changed into the front army, and the front army became the rear army, and fought a bloody way in the encirclement of the Qin army blasted by the bombers, and moved quickly to the east.

Of course, the Qin army would not let Shen Hao leave easily, and the King of Qin immediately urged the Qin army to cross the Blue Star Army's defense line and pursue Shen Hao's troops at full speed.

The Blue Star Army resisted the pursuit of the Qin army with great difficulty, and although there were continuous casualties, the commander Shen Hao still maintained his confidence, because he had just received a message from Lin Da that the large army of the Flying Dragon Legion was already on the way to support, and as long as he held on for another hour or so, the main force of the Blue Star Army would be able to arrive.

On the eastern horizon, a powerful momentum that seems to be able to move mountains and reclaim the sea is rolling in, and the battle between the main forces of the Qin Army and the Blue Star Army is about to break out.
