Grenades are not like shells. Although the explosion range is small, they are targeted. When zombies attack the city wall, the team is not as close as before. After the baptism of artillery fire and the fire of guns, the zombies in many places are not dense. At this time, bombing with artillery fire is bound to waste ammunition.

Therefore, targeted grenades are more lethal to zombies. Besides, in order to reduce the pressure of sniping war, Xu Ying specially prepared many special grenades for these soldiers. What lightning grenades, flame grenades, ice grenades, anyway can prevent the zombie attack, have been prepared a lot, for a time, under the wall, zombies are not frozen, or all over the fire, slowly melting in the flame.

"Commander, this battle is too easy. As long as we have enough materials, we can easily earn our military achievements." The regimental staff officer looked at the corpse that fell down and said excitedly.

"It's not that simple! We have invested 80% of our firepower on this zombie. The main zombie will come soon, and that will be the real test. " The commander did not relax. He stood on a high slope and observed the zombie with a telescope.

At this time, although humans and Zombies engage in fire, and apparently humans are slaughtering zombies overwhelmingly, there are not many zombie vanguards. They just walk along the valley, and the corpses in the back have already covered the valley and climbed to the middle of the hill. This is really called the mountains and fields.

What made the commander more worried was that there was a tall giant zombie in the rear group of corpses. This zombie was obviously not comparable to those low-grade zombies. His skin color had turned iron blue, and even had a faint metallic luster.

The giant zombie left the city with the corpse group. As the corpse became more and more far away from Rome, the brain wave interference device set by Li Yuanhong in the city had less and less influence on the giant zombie. Now he has basically restored control of the corpse group. At the same time, he was far away from Rome, so that the skeleton zombie in the city could no longer influence him.

Zombies also have the concept of territory. Zombies of high rank, such as giant zombies, are reluctant to be subordinates under others. Therefore, when they have a group of corpses under their own control, they will not return to Rome, but will find a place to stand as king.

But on his way forward, there are human beings blocking him. In his opinion, human beings are like food. Now food attacks itself and causes heavy losses to himself, which makes the giant zombie angry.

With a roar of corpses, the zombies, who were still walking slowly on the hillside, suddenly began to rush forward one by one, and the whole group of corpses began to rush towards the sniper position crazily.

The original defensive positions on the hillside were not impacted by the zombies, and they could also help the defensive positions on the hillside to assist in defense. However, the sudden influx of zombies completely confused the positions on the hillside, because they had never considered that zombies would directly attack the positions on the mountain. Therefore, most of the defenses here are mainly sniper guns and rifles. Machine guns and infantry are hardly equipped with these heavy firepower. Therefore, in the face of the tide of corpses, the whole defense system seems to be short of firepower.

"Chief, ask for help. We have too many zombies here. We can't stand it!"

"Damn it, what's the matter with you? It's only a few minutes. Where's your grenade? Throw me a grenade

"There are too many zombies. We don't have enough firepower here. Commander, if you don't support us, you can't defend us!"

The first thing we can't stand is to hold a battalion position above.

"If you can't keep it, you should keep it for me. Even if you are the last one to learn, you are not allowed to step back!" At this time, the commander had to give a death order. As long as he said the word "withdraw", the whole defense line would collapse in an instant, and the troops under him would flee for their lives. Therefore, he must let all people stick to it and not retreat a step.

"Chief, are we really not sending people?" Asked the next staff officer.

"I want to send, too, but now I have only one guard company available."

"Chief, I have an idea."

"What idea? Hurry up, don't you see that the mountains on both sides are almost full of zombies! "

"Yes, commander, when you look at the slopes on both sides, although they are not very steep, they also have a certain slope. In such a terrain, the speed of zombie attack becomes slow, and the dead corpses are not easy to pile up, so the slopes are always clean."

"Well, what do you mean after all this talk?"

"Regiment commander, the ancients always set rolling wood and thunder stones on the hillside."

"Don't beat around the bush. You want rolling wood Thunder Stone. Where can I get it for you now? Even if you get it, it won't kill these zombies now. " The regiment is getting impatient.

"Chief, we have better guys than rolling wood Thunder Stone."

"What? Why don't I know? "

"Commander, it's the oil tanks left by those tank soldiers! That's a big killer

"Yes, yes, yes. How can I forget these oil drums? Hurry up and transport them to the hills on both sides.""Wait a minute, chief!"

"What?"

"We can't just transport it up like this. I'm adding some ingredients to it to ensure that the zombies can eat well!" The staff officer said with a smile.

Soon, hundreds of barrels of oil were made and transported to the top of the mountain.

"We are in a war. What's the commander doing to send us oil barrels?" A battalion commander looked at the oil barrel and asked, what he needed most now was reinforcements and heavy fire support.

"Battalion commander, the commander said, if you don't know how to use this, you don't have to do it!" The messenger said with a bitter face.

"Is that what the chief said?" The battalion commander cast a puzzled look at the herald.

"Yes." The way of heralding soldiers.

The battalion commander turned his head and looked at the oil barrels arranged in a row, thought for a moment, and then suddenly realized, "this is for me to set up the oil barrel array. Quickly, carry the oil barrels to the front line." The battalion commander immediately ordered.

At this time, the front became a pot of porridge, and even some places had fought close combat, and more than a dozen soldiers were injured. It's OK to have a slight injury. If you don't lose your arm, leg, viscera, drink a bottle, you'll recover soon. But if you fight with zombies, once you're injured, it's very difficult to have a slight injury. Therefore, at the rear of the front line, there are more than a dozen seriously injured soldiers. Although these people have no worries about their lives, they may not have a complete life in the latter half of their lives.

Beside these people, there are several corpses. Although the bodies are there, most of them are no longer complete. This is the cruelty of close combat with zombies.

Although some people fell down, the soldiers on the front line were still fearless and attacked the zombies. The whole defense line was like a reef in front of a huge wave. Although the waves were very strong, the reefs were still standing still.

But now the reef is getting smaller and smaller, because soldiers are constantly being carried down to the battlefield. If there is no backup, it is estimated that the reef can only last for 10 minutes.

"Come on, put the oil can down for me, and then roll down!" The battalion commander told the soldiers.

"Battalion commander, why should we go down after all the hard work?"

"Quick, carry out the order!" The battalion commander said anxiously.

The soldiers had no choice but to lift the oil barrel out of the trench, then lay it down and roll down, and soon was drowned by the zombie.

At the moment when the oil barrel was drowned by a zombie, the battalion commander suddenly took out his gun. It was a pistol with a range of 50 meters. However, the power of this gun was much greater than that before the end of the world.

As soon as the battalion commander took out his pistol, he shook his hand, and the bullet hit the oil barrel impartially. As soon as the bullet hit the oil barrel, a spark burst out and a hole was made in the oil barrel.

When the spark meets the oil in the hole, it suddenly makes a huge noise, and even a mushroom cloud rises in the sky. The zombies around the oil barrel are instantly turned into ashes by the fire cloud of the oil barrel explosion, and the zombies around are also blown down. The dark zombies were cleared out of a large open space in an instant, and on the hillside, a big pit with a depth of two meters was blown out.

This explosion made the battalion commander nearly lose his chin. What is the oil barrel? This is simply a high explosive bomb. If his own staff accidentally blew up the oil barrel just now, the whole position will not be guarded, and it will be flattened directly by these oil drums.

"Come on, come on, put some oil drums." Seeing the benefits, the battalion commander immediately continued to discharge the oil barrel.

The soldiers, without the command of the battalion commander, immediately put down the remaining oil drums one after another, and soon another ten oil drums were put down.

This time, the oil drums exploded in the corpse group. Soon, all the zombies approaching the defense line were cleared. The remaining zombies were only those with missing arms and legs, which were no longer in danger.

At the same time, the explosion sounds on the other side of the mountain. It can be seen that the oil barrel on the other side has also been used.

With the help of oil drums, the explosions on both sides of the mountain stopped the zombies' attack on the hillside to a halt, but the zombie group that went straight to the mountain pass did not reduce the attack at all, and the soldiers of the whole battalion did not reduce Half of them have already begun to guard the city and fight against the zombies. After all, the height of the temporary defense wall is not high. If they are given another 10 days and a half months and a dozen meters high wall, it will definitely be easy to block the attack of zombies. But now, the fence is only more than three meters high, and they must use their own flesh and blood to resist the torrent of zombies.

"Send me my guard company!" The head of the regiment looked at the bodies which were carried down with blood, and his heart was extremely heavy. He knew that none of these soldiers had fallen down because of their back injuries. They all died bravely in the face of zombies. He has to hold the pass now, so the final reserve forces have to be sent.

"Commander, all the soldiers have been sent out. Your safety..."

A sergeant asked, worried.

"The positions are lost. What's the use of so many soldiers here? Gather quickly and give me the first line support! If it's lost, I'll have to go up and plug the hole! " The head of the regiment resolutely said.
