Volume One, Chapter 237, Yanjing's Counterattack II
The rubber tube is connected to the blower. As the switch is turned on, the gas in the high-pressure cylinder is sent into the hole. These gases have different colors and properties, but these gases have one thing in common, that is
It's poisonous! Not to mention zombies can't survive in these gases, even elephants can't survive.
Outside the cave, everyone wore gas masks. If the gas leaked out, it would be bad to accidentally injure one of your own people. These gases are not simple, and a casual sniff of them could be life-threatening.
Among the gases injected into the cave, the most lethal one is cyanide compound, and the other ones are sulfide and chloride. As long as the zombies smell these gases, they will soon foam at the mouth and die, and all the zombies in the cave have entered
In the dormant state, zombies in dormancy consume the least amount of energy and can still survive for two months.
Obviously, the zombies did not expect that Yanjing would start attacking when it was snowing heavily.
Tens of thousands of soldiers in the southern region have occupied an area of dozens of square kilometers. Obviously, such a small area cannot cover all the caves in the south, but the area it covers is also very large. Once today's operation is successful, it will only take a dozen
Within days, the zombies in the entire southern area can kill it.
Xiao Sheng and the special forces stood in the distance, watching what happened on the battlefield, and suddenly sighed: "This method is very good. There is no need to cremate the corpses of these zombies. As long as the entrance of the hole is blocked, these zombies can be killed."
It’s a monument, it would have been better if I had used this method earlier.”
Zombies are all hiding underground. Under normal circumstances, human weapons have little effect on zombies hiding underground, and the thick land can insulate them from the severe cold. Zombies hiding underground will not freeze to death due to low temperatures.
.
However, under the attack of poisonous gas, the zombies had no power to fight back and could only be killed one by one. The underground caves they dug before have now become burial places. As long as all the cave entrances are blocked, then
These zombies were buried alive.
The poisonous gas injected into the cave is all gas denser than air. In this way, the poisonous gas injected into the cave will not dissipate for a short time. During this period, no matter how many zombies come to the first layer of the cave, they will not be able to change the status quo.
, because mutated zombies cannot withstand the attack of poisonous gas.
Moreover, if the passage from the first floor to the second floor is not blocked in time, the poisonous gas may sink, further threatening the lives of the zombies on the second and third floors. The zombies on the first floor are irrelevant, but the zombies on the second floor are not important.
There are many mutated zombies and zombie kings on the third floor. This is the core strength. Once damaged, it will be irreversible.
The battle in the southern region finally changed in half an hour. The Zombie King could feel that the number of zombies he could control was decreasing. Although all the dead were ordinary zombies, if this progress continues, the number of zombies in the southern region would continue to decrease.
Most of the zombies will definitely be killed within a period of time!
Under normal circumstances, the Corpse King doesn't care at all about the life and death of ordinary zombies. The number of dead zombies is nothing, but if most of them are damaged, the zombie tide will definitely reduce in size. Under such circumstances, even the Corpse King will
Their survival will be affected! What's more, now that poisonous gas is poured into the ground, tens of thousands of zombies are being killed every minute. The zombie king cannot bear such a drastic attrition rate.
As a result, the Zombie King in the southern region immediately sent out mutant zombies to investigate the situation. Whether they were speed zombies or strong zombies, they were all sent out to investigate the situation. Why were the ordinary zombies on the first floor dying one after another? What happened?
Situation, could it be that humans have begun to attack underground caves?
The Zombie King originally thought that it would be easy for the fast zombies and strong zombies to explore the first level of the cave. Even if they couldn't defeat the human army, they could at least safely return underground to report the situation. However, this was not the case.
The mutated zombies exploring the road never came back, which is exactly what the proverb says: If a meat bun beats a dog, it will never come back.
The zombie kings in the southern region realized something was wrong, so they quickly gathered on the third underground floor and began to discuss the current crisis. The zombie kings were already frightened. They hid in the deepest part of the underground. In fact, they were afraid of what human technology would bring.
The threat, and now ordinary zombies are being killed constantly, this has brought enough pressure to them.
"In the cave on the first level, the passages are full of poisonous gas! It took me more than thirty mutated zombie lives to get the information. Humans have begun to counterattack us!" A corpse king with a scar on his forehead said first.
This information is extremely important. The zombie kings originally thought that winter has arrived. Whether it is their own side or the human side, the war will press the pause button. After all, no one can ignore the impact of low temperature, especially in the north, where winter is
It is common for the temperature to be more than ten degrees below zero. This is a completely natural refrigerator. Who can move around in such conditions?
But reality gave the zombie kings a hard slap. Humans did indeed attack. They launched the attack in the severe cold weather and poured poisonous gas into the ground, which directly caused huge casualties to the zombies.
The zombie kings were unwilling to sit still and wait for death, so they stood up and said: "What else is there to say now? Wake up the dormant zombies, rush out, and kill all the humans who put the poison gas! Let them all die and see if they dare
Don’t dare to have any thoughts about us!”
"Yes, kill them all. It is best to severely damage the human army. It will be easier for us to attack in the spring!"
"The most appropriate choice is to kill one person to serve as a warning to others. Attack is the best defense!"
"Maybe we can kill all these humans and force them to negotiate peace with us. By then, won't our goal be successful?"
There are more than fifty zombie kings in the south. These big-headed zombies are all crowded into a small room, making this stone room particularly crowded. And these zombie kings are busy discussing the next response method. Almost everyone
They all advocated rushing out and killing all the humans above them to avoid causing too much damage.
However, at this time, a zombie king raised a question: "So, you think, how can so many zombies keep warm?"
As soon as this question came out, all the corpse kings immediately stopped their previous cheerful conversations. They had ignored an issue before, that is, the threat of severe cold. As early as when it snowed for the first time around Yanjing, the corpse kings had no choice but to
They had no choice but to retreat, but even so, more than a million ordinary zombies were still frozen to death in the snow. Attacking now is easy, but after rushing out, what else can be done?
Low temperature is a dilemma that cannot be ignored. Any living thing will be affected by temperature, and zombies have all the weaknesses of human beings. The heavy snow falling outside is not just beautiful to look at. This snow can freeze zombies to death.
The outbreak of the zombie virus occurred in the summer. All the dirty clothes on the zombies were summer clothes. Many of the zombies had their clothes scratched when they walked through the forest, so they were naked.
In this state, wearing this kind of clothing to resist the cold is completely whimsical.
Therefore, as long as zombies dare to leave the underground, they will not be killed by humans, but by the ice and snow that can be seen everywhere!
For a time, the stone chamber became deserted. Due to the cold factor, the zombie kings could not send out ordinary zombies to fight, because as long as they left the underground, the number of ordinary zombies would decrease, and the threat posed by humans would not disappear.
"These despicable and shameless humans actually used such despicable methods to attack us when we had no warm equipment. Shameless!" At this time, the corpse king began to curse. In his opinion, these human methods were
It was so despicable that he attacked in the snow, which would have cost him his life!
The other zombie kings also condemned the despicable practices of human beings: "It's really shameless, why do you take advantage of people's danger? If you have the ability to go down to the cave and fight with real swords and guns, let's see who has the stronger fist. Then we will use zombies
They can be piled up to death!"
"That's right, these humans should wait until spring when the temperature rises, wait until we wake up the dormant zombies, and then surround Yanjing again, then they should attack! Really, there is no point in what they do if they claim to be benevolent and righteous.
What does benevolence and righteousness look like?”
Many corpse kings began to condemn the actions of humans, but they scolded them happily, but they couldn't think of a solution at all.
Scar Corpse King saw this scene and said to himself: "Could these guys be the reincarnation of Song Xianggong? The situation on the battlefield is changing rapidly. Who wants to fight with you openly? I won't fight with a bunch of fools."
Be teammates?"
In the end, Scar Corpse King stood up and said in a deep voice: "We can't dictate how the enemy's tactics will develop. Now we can only rush out and fight these people. Ordinary zombies will indeed freeze to death outside, but mutant zombies are different.
, the physical fitness of mutated zombies far exceeds that of ordinary zombies. As long as we activate the mutated zombies in our hands, we can also surprise the human army. Moreover, when the snow is falling, mutated zombies are easier to hide!"
Scar Corpse King proposed that the only solution now is to send the most elite mutant zombies to fight. There are still nearly 20,000 mutant zombies in the south. Once so many elites are dispatched, they will definitely win.
It's a pity that after this suggestion was put forward, it was immediately opposed by the other zombie kings. The zombie king is not a selfless guy. Even if ordinary zombies are dead, they will not let them damage their roots, because ordinary zombies still exist in the south.
There are many, but mutated zombies are not so easy to get. Mutated zombies are the bodyguards of the Corpse King. If this surprise attack fails and they all die, wouldn't there be no bodyguards around in the future?
If there are no ordinary zombies, we can still go to the south to find them, but if all the mutant zombies are dead, the zombie kings will be really vulnerable. After thinking about it, the zombie kings are unwilling to send mutant zombies to do such a dangerous action.
Seeing the faces of everyone, Scar Corpse King couldn't help but sneer: "Are you guys too short-sighted? Do you know what will happen if this continues? Not only the zombies on the first floor will die, but also the zombies on the second floor.
The zombies will be killed sooner or later, and in the end everyone will be trapped underground, with planes in the sky monitoring you all day long. When the time comes, where can you run? It’s totally unfathomable, and you deserve to be where you are now!"
"You make it easy. If all the bodyguards are dead, we will really be helpless. Then we won't even have a chance to escape!"
Immediately, the Corpse King began to rebut.
The two sides argued endlessly, and finally each took a step back. Scar Corpse King's plan must be carried out, which is to send mutant zombies to attack humans, and human poisonous gas cannot continue to enter the ground. However, all mutant zombies must not be sent out. This attack
Humanity's plan can only dispatch five thousand mutant zombies, which is a quarter of the number!
The Scar Corpse King felt helpless about this. How could he achieve the final victory with these insects?
The burrowing zombies re-dig tunnels from the third floor, bypassing the first floor full of poisonous gas, and go straight to the ground target.
In the first layer of tunnels, as long as there are poisonous gas passages, there are no living creatures in them, and the denser poisonous gas is still spreading to the surroundings, and the passage between the first and second floors has been blocked.
to prevent poison gas from entering the second floor and causing greater casualties.
On the ground, Qin Kewei stood on the bare ground, touching the yellow earth with both hands, and was feeling it carefully. Suddenly, she noticed something abnormal, so she quickly took out the walkie-talkie: "Report, the zombies have begun to attack, please pay attention.
On the ground, be careful of zombie attacks!"
When Cheng Ke received the news, his heart suddenly sank. The real test had arrived, so he quickly gave instructions: "Everyone is ready to fight. Prioritize the protection of technical personnel, and secondly protect the gas delivery device. During this period, you are not allowed to take off the gas mask!"
In fact, the method of using poison gas to attack zombies hiding underground has been proposed a long time ago, but no one knew the conditions underground before, so it has been unable to be used because the effect cannot be estimated, and the production of these gases is also very resource-consuming.
Can't be used easily.
It wasn't until Shen Feng came out of the underground that he brought back enough information. Then the headquarters made a decision to use poison gas to attack and kill all the ordinary zombies first! This chapter has been completed!
