With the landing of 16 napalm.

On the battlefield outside the Iron Castle, eight giant walls of flame with a width of about forty meters, a length of two hundred meters, and a height of more than ten meters rose in an instant.

Countless zombies who were charging were suddenly engulfed by these violently burning flames, and they were caught in a sea of fire.

"Exploded! Exploded! In the command room, Zhang Fatzi suddenly became excited when he saw the scene of the napalm explosion, and said loudly: "Damn! What an exaggeration! It really only takes one bomb to blow up such a large area! ”

Qin Cheng smiled: "That's for sure, this napalm is not a joke. Back then, in Cao County, when Lao Mei couldn't beat us, he used this kind of bomb on the battlefield. Otherwise, how could there be a later 38th parallel, and we would have been driven into the sea long ago. ”

Chen Yuan asked with a smile: "I said Qin Cheng, do you sell your technology to make napalm?" We also want to produce, and this thing really works well against zombies. ”

Qin Cheng immediately smiled and said, "Sell!" Of course sell! For a big family like you, the technology is the most valuable to sell to you. But you have to think about it! Really want to buy? ”

Chen Yuan asked suspiciously, "What, what's wrong with this technology?" ”

Wang Luzhou immediately smiled and said: "There is nothing wrong with the technology itself. It's just that on the one hand, the manufacture of this kind of napalm requires a certain chemical industrial base, and you are relatively weak in this regard, so when the technology is in hand, I am afraid it will take some time for you to really achieve self-production. In addition, the throwing of petrol bombs generally relies on fighter jets. Otherwise, it will not achieve such a good effect. And you only have two fighters, so there is no need to produce them yourself. Just buy some ready-made. And zombies won't really let us blow up stupidly all the time. ”

Chen Yuan nodded clearly. Indeed, as Wang Luzhou said, there is really no need for them to produce this kind of bomb by themselves at this time.

At the same time, the Corpse King was equally shocked.

You must know that at this time, the main attention of the defenders on the walls of the Iron Castle is on the zombies who have already rushed up the city walls and are preparing to climb the walls under the walls. There are very few people who pay attention to this side, so the zombie charge is still very dense.

At that moment, at least 15,000 zombies were ignited by the 16 exploding napalms.

The Corpse King hurriedly controlled the ignited zombies to save themselves.

After all, even if the zombie is burned, it can last for a while.

But it soon discovered that these ignited zombies were zombies, and the fire on their bodies could not be extinguished at all!

It's a tragedy.

The harder the zombies try to extinguish the fire, the bigger the fire becomes. In the end, the corpse king could only watch as the 10,000 zombies were burned to death by the fire that could not be shaken off by sticking to his body.

But more importantly, these 8 walls of flames that are more than 40 meters wide and 200 meters long also hinder the progress of other zombies behind!

If the zombies want to continue charging, they will need to spend more time and bypass the sides of the wall of flames.

This creates a troop vacuum at the front for a period of time. It's only a part of the area, though.

But as the zombies in front continue to be eliminated, the zombies in the back can't keep up.

If this continues, soon, the advantage they gained by sacrificing a large number of zombies in the early stage will be cut by more than half!

But there is no way, retreat at this time, and the previous efforts will be directly wasted.

So the zombies could only grit their teeth and continue to attack.

At the same time, it immediately mobilized its flying corpse troops to prepare for another attack by the human fighter force.

Indeed, the Corpse King doesn't think that the human fighter force will only carry out one round of attacks.

The human fighter plane appeared too suddenly, and the corpse king's flying corpse troops had just taken off, and they had already flown away.

But next time, it won't be that easy!

Sure enough, about 30 minutes later, when 8 human warplanes were again ejected near the battlefield with 16 napalms.

The Corpse King's Flying Corps immediately rose into the air to intercept it.

During the day, when the temperature is still relatively high, the speed of flying corpses is still very fast.

It is basically about the same speed as a low-flying fighter jet, and can easily reach a speed of 350 kilometers per hour.

And when dropping such unguided bombs, the speed of the fighter plane cannot be too fast.

However, in the face of thousands of flying corpses, the eight human fighters did not dare to reduce their speed, so they could only drop their bombs hastily and evacuate.

Even 3 out of 8 in the battle, there was no time to drop the bomb at all!

Because from their point of view, the bomb could have hit the walls of the Iron Citadel if it was dropped.

So they preferred not to drop the bomb and went back with the bomb. It's also better than blowing up your own people by mistake.

In the end, in this round of incendiary bomb attacks, less than 4,000 zombies were burned to death.

But the point is that the wall of fire that was burned by the dropped bombs was still the same as before, which caused a certain obstacle to the zombies' attack. Reduced the advantage that the zombies had accumulated before a lot.

So by three o'clock in the afternoon, the attack of the zombie army had not made much progress, and the temperature had gradually dropped below zero at this time.

In the end, the Corpse King had no choice but to retreat.

Once again, the human coalition erupted in triumphant cheers.

Until now, it's really every time you repel the attack of zombies. The morale of the human coalition is one point higher.

Because everyone knows that the power of zombies is gradually weakening.

At this time, the army under the Corpse King was only about 900,000 left.

And the walls of mankind are still standing still!

And the weather is still getting colder day by day.

When the weather was not so cold before, a full 1.1 million zombies were annihilated by them in the battle. What about the remaining 900,000!

So everyone thinks that it is not far from completely defeating the zombies!

It's just that the corpse king at this time doesn't seem to have chosen to give up. After all, 900,000 zombies are not a lot.

However, the weather and the human walls are indeed a big trouble. So at this time, it is making other preparations.

********

In the command center of the Iron Castle, Zhang Fatzi said impatiently: "What the hell are these zombies doing!" All have been retracted for two days, both day and night, neither to attack, but also to retreat. Do you want to settle down here and wait for the spring of next year? ”

Yes, it's November 9th. It's been two days since the last zombie attack. But the zombies never attacked again.

At first, everyone even thought that the zombies had been secretly withdrawn. There was no movement in the entire position.

So Chen Yuan and the others decided to send troops to test it.

As a result, the steel fortress had just opened its gates, but the zombie hordes immediately swarmed again.

As soon as the human forces withdrew, they retreated as well.

A posture of the enemy not moving, I not moving, surrounding but not fighting! This is a big deal.
