The battle for Oil City lasted another 15 minutes. However, in these 15 minutes, the number of zombies eliminated is only one-tenth of the number of zombies eliminated in the first 30 minutes. That's about 4,000 or so.

Such a serious behavior of grinding foreign workers was finally discovered by the corpse.

The corpse general was not an idiot, and it immediately guessed that the humans in the city might be using a delaying tactic.

So he didn't wait any longer, and directly controlled the army of 100,000 elite zombies to launch a fierce attack on Oil City.

Zombies are attacking all over the mountains, but their phalanx is neat, their battle armor is bright, and their swords and guns are like forests, and the momentum and scene are not at all comparable to the chaotic 50,000 ordinary zombies before. It's like the real end of humanity.

On the city walls, many people were frightened by such a sight.

Du Mei gave the order as soon as possible and ignited the gasoline in the moat. Although the moat at this time was actually already filled with zombie corpses. However, it does not affect the combustion of gasoline.

The flames burst into the sky at once, and spread instantly, soon enveloping the entire oil city tightly.

Seeing such a fierce flame, the zombie group was obviously stunned for a moment, and began to slow down slowly under the control of the corpse general.

The defenders of Oil City, who were still facing a great enemy on the city wall, suddenly erupted in fierce cheers, thinking that the flames had successfully stopped the zombies from advancing.

When the zombie horde finally stopped near the burning flames, even Du Mei relaxed a little. I thought happily in my heart: "I didn't expect Chen Yuan's suggestion to be effective, and it really stopped the zombies, these gasolines can't be burned for a while and a half, maybe they can really wait for reinforcements!" ”

But at this time, the corpse general did not seem to be ready to give up so easily, and it tentatively sent some zombies to forcibly cross the line of fire.

Both sides immediately focused their eyes on these cannon fodder zombies.

In fact, at this time, the parallel distance between the two sides was only more than 20 meters, but both sides had a "tacit understanding" that there was no other action. All of them were nervously watching the results.

As a result, the zombies who entered the line of fire immediately stuck gasoline under their feet, and instantly ignited their bodies.

Although zombies don't hurt, even if they have fire burning on their bodies, they still keep going. But soon the fire became more and more intense, and after a while, the brains were boiled, and the zombies naturally hung up. It doesn't last more than 1 minute. So it is clear that a strong attack will not work.

The defenders on the city walls breathed a sigh of relief again.

Du Mei also immediately told Chen Yuan the good news.

"Hmm!" Chen Yuan nodded, but while breathing a sigh of relief, he also continued to ask, "Did the zombie group retreat?" ”

"Nope." Du Mei replied, "It's still outside the flames." ”

Chen Yuan was suddenly surprised and asked, "Then why didn't I hear the gunshot?" Didn't you attack the zombies now? ”

"Ah......h

Obviously, before this, the people of Oil City have selectively ignored this. The psychology of comfort and luck made them afraid that if they attacked first, the zombie hordes would fight them to the death and immediately launch a strong attack. At this time, they all still had the illusion that a little zombie might retreat if they couldn't cross the line of fire.

Du Mei did the same, she asked weakly: "Chief Chen, will this cause the anger of the zombies and make them jump off the wall in a hurry?" ”

Chen Yuan was almost cried by the other party's innocence, and scolded mercilessly: "Are you stupid? You're dealing with zombies who don't die like us humans! Since they haven't left, it means they haven't given up yet. Are you going to watch the zombies extinguish your fire without hindrance, and then attack you? Is this the only way to start a war? ”

Chen Yuan said angrily: "Now the zombies are standing and beating you, you don't fight, you have to wait for the zombies to rush up to your city wall before preparing to fight back!" You're trying to give the zombies more opportunities to annihilate you! ”

"Ah......" Du Mei was suddenly speechless by Chen Yuan: "I...... I'm going to order the troops to attack! ”

But just when she hurriedly hung up the phone and was about to order the troops to open fire, an officer took the lead in contacting Du Mei: "City Lord, it's not good. Among the zombies under the city, an ice mutant zombie suddenly appeared, and it used the method of ice to extinguish a section of the fire wall under our city wall. Now a part of the zombies has successfully rushed to the city. And other zombies are digging up the earth and paving the way! They've found a way to put out the fire! ”

"What!" Du Mei was taken aback, the fire caused by gasoline burning, it is difficult to extinguish the fire with ordinary methods, but the method of covering it with sand and soil is just right, Du Mei did not expect that there would be an ice mutant zombie in the zombie group, and it happened to discover the secret of these flames.

Du Mei immediately ordered anxiously: "Quick! Start firing now, and have someone find some gasoline to sprinkle back on the ice to stop the zombies from extinguishing the wall! ”

So on the walls of the oil city, dense gunfire rang out again.

Coupled with the height of the city wall, the difference between the two sides is only more than 30 meters. Although the zombies have long been defended with shields, the defenders of Oil City have also made good gains.

In particular, the dense plastic surgery of zombies has maximized the power of grenades, mortars, and rocket artillery revealed by the defenders of Oil City.

In addition, Du Mei's method of ordering people to re-pour gasoline also worked. The place where the zombies were frozen also ignited again.

But the zombies also started to fight back.

A large group of zombie archers, neatly bent bows and arrows.

"Bang"

It was like a crisp sound, but thousands of bows and arrows shot out in unison. They flew into the sky one after another, and fell secretly. This time it's really overshadowing the sky. The rain of arrows, made up of tens of thousands of bows and arrows, fell like a dark cloud.

"Watch for secrecy!" At the top of the wall were the officers of the defending army shouting.

The soldiers stopped their attacks and took refuge under the battlements.

But there were still people who couldn't dodge in time and were hit by a dense range of arrows.

"Ah......" screams continued, and some people were even shot directly into hedgehogs, with arrows stuck in their bodies, and even their heads were again, and they died instantly, which made people feel afraid.

But the battle is like this, either you die or I die, there will always be people who die.

As soon as the rain of zombie arrows passed, the officers immediately shouted: "Return to the combat post and keep shooting!" ”

At this time, the zombies under the city had already advanced two or three meters under the city wall with the help of the time when the human defenders were dodging arrow attacks.

It wasn't until the guns of the human defenders began pouring ammunition and gasoline at them again that things got better. The pace of the earth attack slowed down, and the spilled gasoline once again caused some places to burn again.

However, the human defenders couldn't fire a few shots, and the second round of arrows from the zombies came again.

It was another rain of arrows that covered the sky and the sun, and the officers and soldiers defending the city had to dodge again.

And so, alternately attack.

At this time, Chen Yuan and they were still about 40 minutes' drive from Oil City.
