There were even countless tanks and pillboxes at the scene, which were destroyed or blown up by these inconspicuous self-detonating insects.

Fortunately, the entire swarm battlefield, the self-exploding insect soldiers, are not particularly many. It may be that not only the enemy is afraid of them, but even their owners are afraid of them.

At least in the chaotic battlefield, I saw many swarm commanders accidentally blowing up their own troops.

In the entire frontline battlefield of Tianwu City, whether it was the sky or the ground, humans and insects were frantically strangled into a sea of killing.

This is the gathering place of "hope", this is the shelter of "life", once the three strongest lines of defense on the front line are broken by the Zerg, then the 20 million citizens in the city will be in dire straits in an instant.

On the human command platform in the farthest part of the city, the high-ranking commanders of the army closely followed every move of the battlefield situation.

In the sky, there were constantly Zerg flying dragons being killed in a large area by the crossfire network of anti-aircraft guns. It can be said that now the entire human front, that is, the road troops are covering the air defense forces, and the air defense forces are waiting for the elite air force.

"Not enough! You can get more kills! ”

On the command platform, the high-level commander of the human race called through the telescope, calling over and over again in his heart.

As time passed, the wyvern insect swarm in mid-air began to become less dense than it was at the beginning of the war!

"Commander-in-Chief Dou, all the officers and men of the Air Force can go to battle at any time!"

On the command platform behind the human race, a senior command officer of the Air Force reported to Dou Chengwu anxiously.

"It's not time yet!" Dou Chengwu slowly put down the telescope and said lightly.

Dou Chengwu knew that his current words could determine the death of millions of soldiers on the battlefield.

However, he had to wait!

After about twenty minutes, I saw that the swarm of wyvern insects in the sky above the battlefield in the distance became more and more scarce again.

Another middle-aged senior air force officer next to him also couldn't help but say: "Commander-in-chief, the army brothers on the front line are fighting bloodily, and all the soldiers of the air force are asking to fight!" ”

"It's not time yet!" Dou Chengwu's expression was solemn, and he said word by word.

After another twenty minutes, more than half of the ground buildings and bunkers on the front line have been destroyed, and countless tanks and armored vehicles have been scrapped into scrap metal. Army soldiers, having lost bunkers and the cover of armored vehicles, began to have a chaotic situation on the front.

In the distance, the mountains and the plasma worms of the swarm began to bombard the human front even more frantically, as if they never knew tiredness.

This time, even the veteran generals of the Air Force could not sit still!

"Lao Wu, the air force can really fight, the ground forces have now collapsed, and there are now seven big gaps in the No. 1 defensive line!"

"Wait!" Dou Chengwu's expression was resolute and his attitude was resolute.

When the high-level military commanders of Tianwu City who were present heard this, they all looked at each other, what are their commanders-in-chief waiting for!

If you don't fight now, when will you wait?

Is it true that the Air Force will only go to war when the Army is dead?

Once the swarm breaks through the first line of defense of the ground forces, the air defense forces behind will be slaughtered, and humanity will be completely finished!

"Woo-!"

At this moment, in the distant sky, there was a sudden shrill hiss of insect swarms. I saw that suddenly from the mountain peak where the plasma worm was, countless swarms of flying dragons flew up.

Those flying dragon swarms were originally used to protect the plasma swarm on the mountain, and at this time, the lords of the Zerg finally couldn't resist the temptation and joy of victory.

According to the monitoring of the king insect network in the sky, the human front is already on the verge of being broken through and collapsed.

The three major lords decisively decided that it was time to give the human Zuihou a blow, and then move forward to the artillery front of the plasma bug army.

Looking at the flying dragon insect swarm flying in the sky, on the human command platform in the distance, those officers who asked the air force to fight were completely dumbfounded.

It's a game between Patience, humans and Zerg.

It turns out that the cunning lords of the Zerg have always kept a hand!

"Put the seventh, eleventh, thirty-third, and eighth-ninth reserve armored divisions into the No. 1 defense line, and swear to block the seven gaps that have been broken through by the swarm! It is necessary to buy as much time as possible for the air defense forces. Dou Chengwu ordered.

The Blazing Lord left a hand, and he Dou Chengwu is not a vegetarian!

Although the sudden increase in the Zerg air force suddenly tightened the entire human front, the human army could still survive it by relying on the three-dimensional bunker defense line.

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

The barrels of the anti-aircraft units in the bunkers and trenches, the barrels of countless anti-aircraft guns and anti-aircraft guns have long been piping hot, and the shells are placed in piles and piles. All the soldiers have entered a high-intensity combat state, as if the Zerg air force will never be finished.

Reload, aim, fire, reload, aim, fire ......!

The personnel of all air defense forces, nervously and quickly, repeating a series of actions of unlimited shelling.

The number of flying dragon insects in the air is too dense and dense, and they don't even have to think much about accurate shelling, just fire a shot, and they can directly kill three or five flying dragons.

"Whoosh!"

Just when all the air defense forces thought that they would repeat the shelling action indefinitely for the rest of their lives, a row of familiar figures suddenly flashed in the red sky.

The steel streamlined mechanical body, the wide and sturdy wings, and the whole body exuded a thick metallic luster, leaving a clear trail of gray smoke in the sky.

They're on the move!

"Whoosh!"

The air force of Tianwu City was finally dispatched, and countless fighters formed a formation, unfolding a three-dimensional box combat method that echoed from end to end, and roared towards the mountain where the plasma insect swarm was hidden.

In the core escort position of the entire huge fighter formation, countless giant-class bombers, loaded with heavy bombs, will send death greetings to those fat plasma worms on the other side of the mountain.

"All the warriors of the Air Force, listen, I am Chen Yanfeng, Commander-in-Chief of the Air Force!" In front of the roaring fighter group, the voice of General Chen, who took the lead, was heard: "Today, our air force will shoulder the heaviest mission of the 20 million citizens of Tianwu City and mankind!" The sky ahead may be full of endless danger and death. But, my children, when did our Air Force ever fear and when did it fear! Today, let's show these bugs jumping in the air who is the real master of this sky! ”

"The fighter formation is fully covering the bomber formation and implementing a key breakthrough in the middle, the target: the plasma swarm of the Zerg! Not a single one can be left alive! ”

The battlefield sky, which was originally full of flying dragon insect swarms, suddenly roared out of countless human fighter groups, as if pouring out, and in an instant, the entire crimson sky was crowded.

Several well-trained fighter squadrons quickly separated in the sky, one left and one right, and quickly attracted a large part of the dense swarm of Wyvern insects in the middle, diverting the Zerg's air force combat effectiveness.

More fighter formations concentrated their combat power in the middle of the entire sky, firing at full power, and the missiles with long tongues of fire bombarded straight towards the flying dragons and big octopus insects that were blocking in the middle.
