The city is quiet under the protective cover, as if it is entering a sleepy city with a population of tens of millions. Three-quarters of the survivors are subject to low temperature freezing. Most of the remaining people are government personnel or soldiers during their service. They all have strong psychological qualities, have received complete military training, and have relatively strong combat effectiveness.

There are about 100,000 farmers, all of whom are strong crops. They take care of all the wheat seedlings in the city, whether they are planted on the rooftops, on the balcony, on the roadside, or on the square. They are all under their care. Only this batch of wheat seedlings can produce grain to make everyone live.

Governor Bai tried his best to remain calm, and even tried to pretend to be nothing. With the roar of the rail cannons and the zombies and evolutionary beasts going crazy, the protective shield could only last for another four hours, and Governor Bai's heart was completely suspended.

As Hua Yang led the flight brigade to chase the zombies and evolutionary beasts around him, the ominousness in Governor Bai's heart became more and more intense. Looking at the increasingly dimmer protective cover, Governor Bai sounded the alarm of first-level alert.

When the city raises the protective cover, it is divided into three situations according to the guidance in the tactical manual. If it rises temporarily, there is no need to make changes to the buildings in the city, and everything will be the same. If it rises for a short period of time, such as one month or three months, troops must be stationed around the protective cover, and they can fight back and be alert. If the protective cover is raised for a long time, it takes three months, or even needs to stick to it for a longer time, a permanent offensive must be built, and at the same time, reinforced concrete is used to repair the defense line around the protective cover.

Governor Bai was a military blind man. He was mechanical and treacherous, standard and rigid. According to the standards in the tactical manual, after three months of defense, he was built fortifications. The arc wall, which was twenty-five meters high and eight meters wide, was built around the protective cover. The thick base had oblique shooting holes. The entire section of the offensive was buried underground for five meters, which was strong and thick. There were four passes to leave the city. Rows of bunkers were built beside each pass, with high and low undulating and staggered. A tight firepower network could be formed during wartime.

As the alarm of first-level alert sounded, the soldiers gathered urgently rushed to the bunker as fast as possible. The mecha warriors came to the bunker with their energy light guns. The rumbling tracks roared, and the tanks docked in the arsenal rushed out like a awakened beast, turning into a roaring torrent of steel, split into four, heading towards four passes, and the artillery fire was loaded in full swing.

There is a complete industrial foundation in Chengcheng City, and there are chariot factories in the suburbs. In an underground military base, there are missiles already placed on the launcher. The originally quiet city has now become quieter, with a cold murderous aura in the silence.

Li Ruopu looked at the protective cover that was gradually dimming outside through the plexiglass, and his brows gradually frowned. These days, the protective cover changed and could not avoid the eyes of those who were interested. With a little attention, you can guess the zombies surrounded the city. There is no words on the top. The bottom pretends not to know. As the situation gradually deteriorates, he finally reaches level one alert.

Li Ruopu looked at the gradually dimming protective cover and thought silently in his heart. Can he really hold it? I hope he can hold it!

In the vast sky, the airship opened the cabin door, and 60,000 drones rushed down, and five rail guns burst out one after another. They slashed the black tide in half like a gate. There were about two million in the black tide outside, gathering on the ground. The drone circled and dived down, and the muzzle roared at the zombies and evolution beasts below and began to spit flames.

Boom boom boom! Boom boom boom! With the precise calculation of the matrix, the kill rate reaches 50%, and the first round kills 30,000 sinful lives.

"Everyone attack!" Condescending without worries, Hua Yang had no scruples: "Helicopter, scatter the energy box in the rocket's nest." With a command, seven hundred and fifty helicopters spewed flames at the same time, boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom boom bo

"Stop fighting!" The plasma cannons on the airship roared, and white lights roared like angry dragons, roaring towards the evolutionary beasts on the ground.

On the pyramid of power, the strong will always be the top of the pyramid, and the rest will be the foundations of the tower. The first-level zombies and evolutionary beasts are the most, followed by the second-level, the third-level, and the fourth-level is still evolving. As for the possible fifth-level, Little Red Riding Hood's eyes widened and searched inch by inch.

Guanying has some research on the evolution after the catastrophe, but it has not found the reason for the formation of the black tide. One x factor can make the zombies and evolutionary beasts in four to five cities form a black tide, which is incredible and possible. The key is to capture the pair of black hands hidden behind the scenes.

Chen Degeng narrowed his eyes slightly, and the vertical eyes in his eyebrows flashed brightly. A mirror-like display screen was distinguishing and comparing the zombies and evolutionary beasts below one by one. His faces were dull, and he found nothing until now.

Looking at the gradually sparse black tide below, Hua Yang frowned. Could it be that the x factor is no longer on one side, but on the other side? The firepower net keeps ringing, and the rocket nests hanging on both sides of the helicopter are spraying down in a series. The soil on the ground is blasted into a pothole. The cannon fire roars, flesh and blood fly, and the energy is destroyed after the explosion. The entire world has become a killing field. If there are psychic eyes, you will definitely see the soul floating in the void wailing.

The zombies and evolutionary beasts that had just gained wisdom were panicked when they could only be beaten. As the number dropped sharply, there were still 800,000 left for the two million black tide. The weak were dead, and the strong were in danger. The already chaotic command system jumped into pieces in an instant. The 800,000 zombies and evolutionary beasts were as messy as if headless flies were flying around.

Boom boom boom! The rocket nests gushing in the sky stagnated one by one, and a unit of artillery fire shone. The pilots hovering in the air were still unsatisfied, and an hour had passed, and the already dim protective shield has now become even more dim.

"The helicopter goes back and replaces the energy box." Hua Yang said and knocked on the eyebrows: "Have the transport plane returned?"

Opp opened the satellite map in Hua Yang's pupil, and the transport plane had completed airdrops and was about to land at Luyang City Airport.

Hua Yang knocked on his chest and connected Lu Heping: "Send fighter jets to come, loaded with weapons to attack the zombies and evolutionary beasts around the protective cover." The rail cannon is too powerful. Although it is positioned accurately, it is afraid of accidents. After the already unstable protective cover is hit, it will break in an instant.

Buzz! Buzz! The fighter slowly landed on the ground, the pilot was wearing a helmet, looking a little depressed, chewing gum, and shouting at the communicator: "003, we are fighter pilots. Today we are escorts. Is there any difference between it and a flying transport plane?"

003 replied: "004Don't complain, look at the 001 and 002 that you can't see below, but they can't fly even if they want to!"

004 glanced down and found that the two fighter planes parked next to the runway were being pulled by a tractor. Various missiles were hanging on the wings. 001, who was still depressed just now jumped into the cockpit with his eyes flying, and putting his helmets on his head with quick hands and feet. 004 couldn't help but ask: "001, are you going there? Are you also escorting?"

"Protect your sister!" 001's words were smug: "Brother has a combat mission, so I won't say much to you. 002 keep up." The fighter accelerated on the runway, and the engine roared and spewed out dazzling flames. The fighter was like an eagle flapping its wings, instantly penetrated the sky.

Looking at 001 and 002,004 who were flying high, muttering: "Why are they just fighting tasks? We are all escort tasks! This is unfair, unfair!"

003 flattened his mouth and was about to say something, when the communicator in his ears rang Lu Heping's voice: "003,004 You have two hours to rest and take off to fight in two hours."

Both 003 and 004 felt excited and said with a heavy mouth: "yes!"

The helicopter formation returned to Decheng City, where to replenish ammunition and flew forward along the city. Suddenly, a small black eagle that had been hiding in the sky, could not control the murderous intent in his heart, flapping his wings down, and a trembling sound came from his mouth, and his claws were like hooks, grabbing the propeller made of steel.

Bounce! The sharp claws grabbed the propeller on the helicopter. The helicopter that was originally flying forward suddenly stopped in mid-air, and then crashed into the ground like a meteorite. With a roar, it shattered and turned into a dazzling and flashing fireball.

"Attacked! Be wary! Be wary!" The leading pilot Wang Rumo said angrily: "The ammunition in my rocket nest is finished."

The sound of annoyance came one after another. The helicopter pilot had already empty the rocket nest. Facing the giant eagle flying high and falling, everyone had no choice but to do anything. Like the fat meat on the chopping board, he could cut it freely. He could only watch the helicopter fall.

"You go forward at full speed, we will leave behind the rear!" Wang Rumo chose a short tail like a gecko without any help, leaving more than ten helicopters as bait to cover the evacuation of the large army. At the same time, he opened the communicator: "Call the officer, call the officer, our army was attacked by a giant eagle, request support, request support." After saying that, his teeth clenched and ordered again: "Brothers fly next to each other, we dare to bump into it if it dares to come."

The Giant Eagle chose an extremely tricky time. After the helicopter team finished fighting the rocket nest, they already had wisdom birds with an IQ of nearly a child. They soared in the sky and began to awaken their wisdom before the catastrophe, so they evolved and improved.

"Damn it!" Looking at the scene in the satellite, Hua Yang was furious. This bastard was really clever in grasping the battle situation. He also blamed himself for being too greedy and let the helicopters slam the rocket nest. Seeing the helicopters fall, Hua Yang gritted his teeth and grabbed the intercom: "Stick, you must hold on, support will arrive soon!" The two fighters in the distance suddenly accelerated and turned. The already complicated battle situation has become more complicated now.
