The start of science and technology

"Yunzhou Base, to face China's largest animal trend!" In Yunzhou Base, everyone is uneasy.

Here, there are more than 40 million people living, most of which are migrated from Yunzhou. They left township and live here.

Now, those variability beasts have been chasing, surrounding more than 40 million people's fortress cities!

"Can we defense?" The entire fortress city is filled with a nervousness of the stress, don't say that ordinary people are, the full deputy armed soldiers are not in the heart.

Demonstry, the variability beasts are not only repeated, but more and more stronger!

"Be sure to keep Yunzhou Base!" The whole Hua Guo is in troops and travels to Yunzhou Base.

"This is our abdominal area. If you are strained, the whole land will be directly exposed to the threat of variant creatures!"

"All military supplies, the first time to protect the Yunzhou Base!" The whole god is up and down, it will focus on the Yunzhou base.

Recently, all cities are very tight, even so, they still want to take persons and materials to go to Yunzhou base defense.

Everyone understands that this battle is very important! The soldiers and biochemical plants have been produced in the day and night, and there is a battle in the replenishment line.

The variabase seems to know the importance of cutting off the supply line, and the mutated biological attack is sent, and the Guards are 24 hours of preparing for the status of the train and the aircraft.

......

"Can Hua Guo Yunzhou Base?" Not only the country, the high-level and people around the world are paying attention to this battle.

So far, only the situation of China's land is generally preserved under the invasion of variant creatures. In other regions, even the most military power is now stronger, and it is difficult to survive under the attack of variant.

Yunzhou defensive battle is not only to guard the security of Yunzhou people, but also the hope of surviving humanity around the world!

"Be sure!" On a island in Asia, the people silently prayed, and their living area has long been mutated, and the hope of survival is rely on Hua Guo.

"Yunzhou is at least more than 500,000 variable biological attacks. This is the biggest animal trend in Asia!" The Kingdom of Peacock, the high-level, the high-rise, the inner cold.

This time is a bombing of hundreds of nuclear bombs, and it is estimated that all them will be eliminated!

What's more, next to Yunzhou Base, they can't easily use nuclear bombs.

Africa, this is the fastest in the United States after Oceania. Today, survivors gathered in a few fortress cities, focusing on Yunzhou defensive war.

Western Europe, those who have aggregated and resist threats from the Atlantic variant.

For the beast trend in Yunzhou, they can only make electricity condolences.

......

"Level 1, secondary variability beast, is expected to be around 450. We must use all the firepower, it is possible to block them!" On the eve of the war, the headquarters of Yunzhou Base, a group of commanders are negotiating tactics.

"Three-stage variability beast, the number is expected to exceed 30,000! Every must have a hot weapon to combat team to cope, and the army of our Yunzhou, a total of 300,000, whether the number is still a weapon Coping! "A commander said.

"Is this really necessary to use nuclear weapons? There are also five-level variants in the nest, even the six-level variants. If nuclear radiation makes them more evolved ..."

The smart body in the nest made everyone in the heart of the shadow, until now, they don't know what the commander of the beast is like, what is the high-grade variant, how to have the combat power.

"Continue waiting, the first batch of biochemical weapons is still on the road to transportation." Du Xingyu said.

Time has been in the past three days, the beast is already stupid.

They are getting closer and closer from Yunzhou Base, some of which have rubbed with humans. Humans will launch a shell attack every day, but the effect is small.

There are variability in the animal boom to intercept the shells, and weapons such as burning bombs will also be extinguished by the concentrated fog of variability.

At three in the morning, Du Xingyu has entered a sleep, suddenly happening dramatic explosion, the fire will illuminate the whole sky, and the air defense alarm sounds over the city.

"The trend is attacked!"

"Happy organization hide into biochemical protection!"

"Yunzhou combat troops are preparing to fight!"

"Open the air defense system!"

"Pay attention to the normally varied creatures!"

......

"The beast is attacked?" Du Xingyu sat up and passed the biological computer, he immediately connected the computer system of the headquarters and accepted information.

It can be seen in the monitoring screen that a large number of variation beasts began to rush into the Yunzhou base.

External defense line, automated weapons are constantly spraying bullets, missiles and flames block them, and the burst of the beasts rises through the night sky!

"The death, actually taking advantage of the night sneak attack!" In the headquarters, the commanders have all rushed and started to command the battle.

"The first wave is mainly a secondary variant, and our firepower should be able to stop! It is mainly to focus on variant poultry and normally in the sky!" The commander Feng Zi said.

"The fighter has been lifted, coupled with the air defense system, there should be no problem on the sky. The masses have been transferred to the biochemical defense facility."

"Various night vision ability is better than us, not good for us to fight. Open the outside of the light light, first guard, observe the enemy!" Li Taichao.

Du Xingyu rushed to the headquarters and said: "General, we must find the command of the beast!"

"Is the wisdom of the nest come out?" Everyone was suspected.

"No, it should have no movement." Du Xingyu analyzed the road, "the five-level variant has human wisdom, enough to command the beast tide. These variations are dare to attack us, must have a five-level variant!"

"Must find them, kill them!"

"Good!" Li Taige, he shouted in the communication device: "Attention to each unit, find the five-level variant of the beast, once found, immediately report!"

The snoring of gunshots, explosions and the beasts were practiced, and the entire Yunzhou base was shaking!

In the biochemical control office, the people are afraid to hide inside.

"Mom, will the monster eat us?" A little girl hid in the arms of the mother trembled.

"No, uncle's aunts are resisting them, they will drive the monsters!" The mother comforted, but her inner heart is equally full of fear.

Others are silent, and some people are crying.

"Don't be afraid, I believe we will win!" The staff of the protective house comforted them.

......

Time has passed over an hour, the first wave of the beast is stopped. But this wave has caused huge losses to humans. The first layer of defense in the three-layer line has been basically paralyzed, and many automated military facilities have been destroyed.

"The boasts are collecting, they are preparing the second wave of impact!" In the headquarters, Du Xingyu and the commanders pay attention to the war status in real time.

They found that the first wave of striped beasts, their bodies were being tedyed by companions, and even some secondary variants were swalloweded by the body of other variants, the Z viral concentration rose, and started evolution with the speed visible to the naked eye!

"They have become stronger in battle!" Nie Xinling of biochemical experts took a deep breath and said: "The number of three-level variants of the beast, will exceed our expectations!"

"Is the second layer of defense ready?" Du Xingyu asked.

"Ready." Li Ta said, "The second floor is very close to the city, and the third layer is basically the edge of the fortress city."

"The second floor defense is at least three hours." Du Xingyu said, "At 7:00 in the morning, the first batch of biochemical weapons can be sent."

"Three hours!" All commanders felt huge pressure, the first layer of defense only supported an hour, and now the attack variability is stronger, three hours, it is too difficult!

The front line, the soldiers are in an emergency.

The wounded from the first layer of defense is sent to the rear treatment, and there is also the direct compilation of the combat power to continue to fight.

High-tech guns, empty missiles, including laser weapons, are ready.

"Brothers, we must support three hours!" The front line commander will order. "No matter what method is to die, you have to hold these three hours! Wait until Deniang, support it!"

"Yes!" The soldiers have already been degrade!

"Torked ..." is another second sound wave that is emitted, and the variants heard the command and start impacting the second line of defense.

This time, the first rush is a three-level variant!

The body type exceeds the bones of the armored car, the fierce double-headed blood, the violent iron tyrant, and the madness and other variants began to impact the defense line!

"Bang!" The huge cement wall built by a reinforced concrete was directly broken by the bone giant. It was a mortal gun to fight it, but it was embarrassed to break its outer skeleton. Rush!

"Block, stop them!" The laser weapon has started, and the high-fever laser holes wear these variants of the body, and they will be half a half!

But these still can't stop their impact, these variants don't know what to die, desperately rushing.

Those defensive amazing advanced variations are in front, and the firepower cannot be covered by them. From time to time, there is a variant body and the soldiers immediately control the weapons and fight them.

"It's too fierce! Only two hours and 14 minutes, we lose 40% of life!" Li Tai's mood is very heavy, the ammunition stock is also calculated, and the soldiers who sacrifice will come back.

"Five-level variants, haven't I found yet?" Du Xingyu clenched his fist.

"Found!" In the communicator, the second layer of defense commander shouted.

"In the northwest corner, there is an appearance, five variants!" His voice is full of horror, and even with despair!
