***************

After the failure of the fifth attack, the strength of the zombies had dropped to 1.15 million.

Although this number is still very large, pulling it out, it is also all over the mountains and countless places.

You must know that in peacetime, Lao Maozi's military strength in the north is strong, known as the second largest military strength in the world, and the total strength of the country is only a little more than 1 million.

But the people of the three families had already been able to resist the attack of 1 million zombies before, and it was still winter, which also made Chen Yuan and them feel completely relieved.

Then the next day, the war continued.

Sure enough, the zombies took advantage of the rising temperature during the day to launch a new round of attacks on the Steel Castle again.

Although the number of troops invested by the corpse king this time is only 1 million, the speed of the zombies during the day has been greatly improved, and even around noon, the speed of the zombies may return to its heyday. So the combat effectiveness of the 1 million zombies during the day is actually higher than the 1.2 million zombies at night!

However, for humans, there are also many advantages of the day.

First of all, the attack range of the officers and soldiers has been increased.

Far away, the human defenders on the city wall began to attack the attacking zombies, and the accuracy was also greatly improved.

In this way, zombies naturally have to pay a certain price.

And during the day, the No. 2 gift that Chen Yuan said they had prepared for the zombies could finally be used!

*****************

"Tower! Control tower! Shenwu 01 (02 and 03) is in place, now apply for takeoff! ”

On the military airfield of Gedachi, the Iron Fort. Three fighter jets from the Shenwuguan settlement were already ready on the runway, and the pilots spoke to the console at the Gedaqi airfield and asked to take off.

And the console's reply was not long in coming: "Agree to take off!" Good luck and prosperity! ”

"Roger, thank you!" The pilot saluted with two fingers in the direction of the tower.

Then, I only heard the sound of the engines of the three fighters on the runway suddenly and instantly became louder, and the entire fighter formation also rushed out to the other end of the runway.

And a little later, under the control of the pilot, at the same time flew into the sky.

Then the three fighters in Yangcheng and the two fighters of the Self-Rescue Army did the same, and they took off one after another after the fighters in the Shenwuguan settlement.

A total of 8 fighters flew from Gedaqi to the southwest, that is, from the direction of the Steel Fort.

Yes, because it was daytime, and the air forces of the coalition could finally be dispatched.

In fact, it does not mean that the human air force cannot attack at night, these fighters are all third-generation fighters, and they are fully capable of night fighting.

It's just that the bomb they used this time was a bit special. And not precision-guided bombs. Therefore, the error will be relatively large when throwing.

Especially when throwing at night, it is easier to make mistakes, and if it hits your own head, it will be over.

You know, the special bomb they are going to use this time is very terrifying.

In the past UN banned and restricted weapons list, there are much more terrifying than white phosphorus bombs!

It's called napalm!

That is, the second gift that Qin Cheng prepared for the zombies this time.

When this bomb explodes, it can produce dense high-temperature flames, with temperatures exceeding 1,000 degrees!

And inside the bomb, a gel made of gasoline and other chemicals, will sputter in all directions when it explodes. And it can stick to other objects and burn for a long time. It's much more resistant to burning than white phosphorus bombs!

This kind of fire can't be swatted, because the flame will only get bigger and bigger.

You can't roll on the ground to extinguish the fire, because the flames will quickly burn all over the body.

Even water cannot extinguish these flames, because the active alkaline metals added to napalm, such as calcium, barium, and other metals, are combined with water, and the hydrogen gas released will be burned again, increasing the combustion power.

What's more, there is no water near the Iron Castle at all.

Once there is a lot of fire on the person, the people on the side should try to stay away from the person on fire, because the struggle of the person on fire is easy to throw the burning oil block on the person to form a secondary killing effect!

In addition, if this bomb is dropped by an airplane, the effect is even more terrifying!

After dropping, the bomb will continue to roll in the air, and when it touches the ground and explodes, the bomb will continue to rush forward under the action of inertia, and it can burn a large area at once, at least 200 meters!

That's really a place to go, and there's not a single grass left! Imagine how terrible it would be if even one of such bombs landed on the walls of the Iron Castle!

So Chen Yuan, they haven't had a chance to use it before. Because in the past, zombies hid underground during the day.

This time, the zombies chose to attack during the day, but they can finally get a taste of the power of this weapon!

It's just that there aren't many napalm bombs brought by Shenwuguan and Yangcheng this time.

In the past, this kind of bomb was relatively burned in the building.

These bombs were later redeveloped and produced, and like white phosphorus bombs, not much was produced.

Moreover, the production cost and difficulty of such bombs are even greater, and this time the two families only brought a total of 32 bombs.

And 8 fighters, each of which can carry only two, because each such bomb weighs more than 250 kilograms!

As for why the air force units of the human coalition do not use guided bombs against zombies.

Please, such a precious thing as a guided bomb can be used to blow up ordinary zombies?

Then no matter how rich the Steel Castle is, it can't afford to use it, okay!

This kind of bomb can only be used against corpse generals or mutant zombies.

But corpse generals and mutant zombies are not easy to find, let alone corpse kings!

*****************

The human coalition air force units that had taken off from Gedaqi soon arrived near the Iron Castle.

At this time, the battle on the ground has entered a white-hot stage.

The zombies have just stormed the walls of the Iron Keep, and are fighting for territory with the human defenders on the walls.

This time, because the zombies have regained their mobility, the combat effectiveness is really amazing.

The human defenders on the city walls were barely able to hold their positions with the help of a large number of adepts.

But the casualties were severe.

And the Corpse King's confidence was greatly increased because of this.

It's just that it seems that every time the zombie army of zombies just rushes to the walls of the Iron Castle, the human alliance and even God have to give the zombies a little bit of a son.

Before it was tank troops and cold air.

And this time it's the air force of the human forces.

Soon, the fighters in the air had already begun to dive to the ground.

In the majestic roar of fighter jets, 16 napalm bombs were dropped from the sky and landed outside the Iron Castle, in several areas where the zombies charged the most!

"Boom!"
