At around 3 o'clock in the morning that night, the Corpse King had basically completed the collection and assembly of the scattered troops. At this time, there were a large number of zombies hiding in the anti-artillery trenches they had dug in advance.

They thought it would be foolproof! According to past experience, such trenches have a great defensive effect on human artillery.

Unbeknownst to them, at this time, the artillerymen of the Self-Rescue Army had already begun to load the artillery with shells and were ready to launch an artillery attack.

In fact, Chen Yuan didn't know that the Corpse King was preparing to start the attack the next day, otherwise it would be better to wait until daytime to carry out artillery bombardment.

But it doesn't matter.

Because the shells that the artillerymen of the Self-Salvation Army are loading are not ordinary shells, but white phosphorus shells!

This is a very terrifying incendiary munition, which contains a large amount of white phosphorus and thermite (a kind of aluminum powder material), and once it explodes, the aluminum powder material will be ignited by white phosphorus, producing a high temperature of thousands of degrees.

In addition, after the delay is set, the shell can explode over the target, and a large amount of burning aluminum powder will be splashed everywhere like a flour bag bursting in the air.

The killing area of a white phosphorus bomb can reach the size of 6 basketball courts! It is considered a weapon of mass destruction.

Moreover, there is usually an adhesive in the incendiary agent, which makes it difficult to shoot off the burning aluminum powder once it sticks to it, which is very dangerous! Countries generally try to avoid the use of such shells in populated areas.

But now it's even better to deal with zombies.

This is also one of the gifts that Shenwuguan Settlement and Yangcheng brought to the zombies this time.

However, due to the shortage of materials, the production of this kind of shell is very small. This time, Yangcheng and Shenwu Pass only brought 1,000 pieces, which is all the ammunition produced so far!

***********

The shelling of the self-salvation forces soon began.

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

As the sound of shelling sounded, white phosphorus bombs were sent out by the artillery of the self-rescue army and flew to the zombie position a few kilometers away.

Only two or three seconds later, Chen Yuan, who was standing on the city wall, saw the sky in the distance, and a large number of "fireworks" lit up in an instant!

That's exactly what the self-rescue army's white phosphorus bomb looks like when it explodes over the zombie position!

"Haha! Exploded! Exploded! Zhang Fat, who hadn't slept all night, shouted excitedly. Surrounded by 2 million zombies outside, even Zhang Fat couldn't sleep peacefully.

Chen Yuan and Qin Cheng couldn't help but be overjoyed.

Watching a large area of aluminum powder that was burning violently from the air to the zombie position, they knew that the zombies might suffer next!

Sure enough, after a while, in a large area of zombie positions covered with aluminum powder, there were immediately countless dense roars of zombies. Apparently quite a few zombies have been tricked.

And then, Chen Yuan and the others saw a large number of zombies with flames on their bodies, jumping out of the trenches full of smoke in droves.

They danced and rolled on the ground, trying to knock or extinguish the flames on them.

But to no avail!

Although the flame of thermite burning is not large, the temperature is high and it is difficult to extinguish. And you can't shake it off if it's stuck to your body!

Therefore, the actions of the zombies not only did not extinguish the flames on their bodies, but instead made the flames even bigger.

After a while, the zombies were burned into fireballs.

"Hahaha! Great, I didn't expect the effect of the white phosphorus bomb to be so good, I think there must be at least tens of thousands of zombies burned here! Zhang Zeshan laughed happily.

"That's right! At least forty or fifty thousand! Du Ruhai took the telescope and kept patrolling the overheated zombie position, roughly counting the results. He also smiled happily and said: "If you can give zombies so many times, it is estimated that 2 million zombies will have to finish!" ”

Qin Cheng said with a smile: "You kid thinks beautifully, do you know how much effort we spent to make these 1,000 white phosphorus bombs!" This is the output of our Heyang City for nearly 4 months! ”

"Hehe, didn't I just say that! If only this cannonball were easy to build! ”

But Chen Yuan said with a smile: "Don't think about it, the structure of white phosphorus shells is much more complex than ordinary shells." And even if it can be mass-produced, zombies are not so easy to solve! We're just caught off guard by the zombies now, and if we use it too much, the zombies will definitely find a way to defend against white phosphorus bombs. Don't underestimate the wisdom of the Corpse King! ”

Hearing Chen Yuan's words, everyone couldn't help but nod in agreement.

Indeed, they have been fighting zombies for more than three years. After the first year or two of panic, after mankind gradually gained a foothold in the last days, various advanced tactics and weapons were gradually introduced, and zombies were given a lot of losses again and again.

But the progress of zombies is not slow, and every time humans have new tactics and weapons, zombies can always adapt quickly. Just like Chen Yuan said before, the same tactic can't be used on zombies twice in a row!

*********

At the same time, somewhere in the zombie position opposite, the corpse king of Qiha City was also in a big panic!

It had no idea that humans still had this hand! It was possible to ignore the role of the trenches and drop the attack directly into their bunkers!

And it is also a large-scale group attack. Just that round of attacks has already caused it to lose nearly 50,000 zombies! It accounts for one-third of the total zombie strength in the attacked area!

(Actually, these zombies are not dead at this time, but they are no longer saved!) The fire is so evil that it can't be extinguished at all. The Corpse King can only control the zombies that are not on fire to hide away from them and prevent them from being ignited as well. So these 50,000 ignited zombies have been classified as dead by the Corpse King! And in less than 1 minute, these zombies on fire were indeed burned to death! ）

It's a good idea! Although it has an army of 2 million zombies, it can withstand several such attacks!

However, as Chen Yuan said, the Corpse King, who controls countless zombies, quickly discovered the weakness of this new human weapon by summarizing the zombies that did not have an accident in the attacked area.

That is, the attack of this weapon is not penetrating. As long as there is a thin layer of cover on the head of the attacked area, the attack is ineffective.

So it's easy to defend, just add a roof over the trenches.

(And what the corpse king didn't know was that in fact, the round of shelling just now had already consumed half of the current white phosphorus bombs in the hands of the self-rescue army.) In other words, with a white phosphorus bomb attack of this scale, the self-rescue army can only last two rounds. ）

It's just that for a while, the Corpse King can't immediately conjure up the roof.

The second round of artillery bombardment by the self-rescue army began immediately after readjusting the angle and aiming at the other positions of the zombie group.

This time, more than 50,000 zombies were also stuck to the zombie position attacked by white phosphorus bombs!

The corpse king, who has an experience, knows that this kind of flame cannot be extinguished by ordinary methods, and the high temperature of thousands of degrees, even if it is covered with soil, the high temperature can simmer the zombie whole! Ignore it, but it can make zombies live longer.

So the angry Corpse King simply controlled the 50,000 zombies on fire and the other 50,000 zombies that were not on fire and rushed to the Iron Castle on the opposite bank! Launched an attack in advance!

At the same time, the Corpse King also hopes that these attacking zombie troops can attract firepower for the main force.
