Inside the Xi'an Fortress, there was chaos in the command center General Yang Hua looked at the huge display screen in front of him and frowned, "How is the city wall?" ”

"Report to the General, everything is going well on the other side of the city wall!"

"That's good!"

"General! This is a catastrophe! ”

"Yes! It took less than a day for this zombie to level the Patriot Fortress, although the Patriot Fortress is private, but the strength is not weak, and now their fortress is broken, not only bringing us a large number of refugees, causing a shortage of our land and food, but also increasing the number of zombie troops, the Patriot Fortress is nearly 100,000 people, and at least two-thirds of these 100,000 people have become zombies and entered the zombie team! Although zombies don't have brains, it's also a big threat to us! ”

"Yes! Let's hope we can survive this catastrophe! ”

"By the way, Lieutenant Tian Jie, how are they preparing for their mission?"

"Everything is ready to go! It's just that this mission is afraid... I'm afraid I won't be able to go back again! ”

"This mission is what he wants to do! After all, he still remembers the matter of the artificial island, who doesn't remember this matter, so many brothers have died, of course he wants revenge, if he wants revenge, let him go! Hopefully he can make it and come back alive! ”

......

"Lieutenant Tian Jie, are you really going?" Hawkeye held his sniper rifle and asked Lieutenant Tian Jie, who was sitting opposite, "Of course!" If you don't kill him, you can't get rid of the hatred in my heart! ”

"But you should know that this mission will definitely go back again!"

"It's okay! Kill him, not only to avenge the brothers, but also to keep the fortress! It's worth dying! Lieutenant Tian Jie said and looked at the sky! Thinking of the brothers!

The zombies are getting closer and closer to the fortress, and this is not embarrassing that the fortress is also in the most tense state, at night, the entire fortress is brightly lit, and the huge searchlight shines into the distance! The inhabitants close to the walls are evacuating to the shelters inside the fortress, all the soldiers are holding on to the walls, and the missile launchers are ready to launch at any time...

At dawn, the zombie army was less than two kilometers away from the fortress, the soldiers stood on the city wall to check their weapons for the last time, and Lieutenant Tian Jie also took three brothers to obey the order at any time and give the zombies a fatal blow! The civilians of the fortress had already been evacuated to a safe place, and at this time, the voice of General Yang Hua came from the loudspeaker of the fortress!

"Dear residents of Xi'an Fortress, friends, and soldiers who are now sticking to their posts, workers on the front line of military factory production! I am the manager of Xi'an Fortress! Admiral Yang Hua! Today, we have to face this catastrophe! The number of zombies this time is incomparably huge! And among the zombies, there is a zombie with human intelligence! But it doesn't matter, I believe that under the blows of our heroic soldiers, under the suppression of our high-tech! The zombie hordes won't break through our strongholds! We need to take courage! Fight the zombies to the end! ”

"Fight to the end! Fight to the end! General Yang Hua's generous speech inspired everyone's morale, and the soldiers were gearing up and ready to do a big job, and in the military factory, the equipment was fully open, and the production was fully carried out, so as to do a good job of logistics support for the front line! Some civilians even walked out of the shelter and applied to join the logistics support team to send supplies to the front-line soldiers!

"They're coming!" The soldiers on the city wall saw the zombies in the distance and shouted, "Everyone prepare to fight!" "Orders came from the loudspeakers of the city walls and the headphones on the ears of the soldiers!" Click! Click! The sound of pulling the bolt resounded over the city walls! As the zombie tide progresses, a foul smell gradually comes! That's the smell of corpse decay, because zombies only rely on brain waves for activities, so their bodies are completely dead, so it won't take long for the zombies' bodies to decay, of course, zombies bring people not only olfactory impact, but also visual impact! Due to the decay of the body, the stomachs of the zombies are covered with maggots, some of the zombies have their intestines exposed, and some even lose half of their faces and continue to move on...

"Wear a gas mask!" In order to prevent the impact of the huge smell of zombies, the army has long been equipped with gas masks to protect the soldiers!

"Sniper shooting!"

"Boom! Boom! Boom! "The snipers who have already locked on to the target start sniping high-level zombies when the zombies are still a kilometer away from the city wall! Except, of course, for one! That's Hawkeye, although Hawkeye is also in the sniper's position, but he didn't shoot, but looked for something, the effort paid off, and after a few minutes of searching, Hawkeye finally found his target!

"Boom!" After a loud sniper shot, a giant axe zombie fell to the ground! "Click!" The bullet is fired, the cartridge case is automatically ejected, and the next bullet is immediately in place, waiting for the moment when the trigger is pulled at any time, "Boom!" "Another shot! Another giant axe zombie also fell to the ground, what kind of gun has such great power that it can penetrate the hard helmet of the giant axe zombie!?

"Whew~ This shot is really powerful!" Hawkeye couldn't help but sigh after firing two shots, "Anti-materiel sniper rifles are just different!" "That's right! Hawkeye uses the famous anti-materiel sniper rifle, the Barrett M82A1¹

"Roar!" The director hiding in the zombie group saw that the two giant axe zombies were sniped, and roared angrily, and the zombie group gradually became agitated, and the zombies began to attack!

"Attention everyone! Listen to the order and fire! "Huang Xu stood on the city wall and commanded the army! The zombies are getting closer and closer to the city walls, and the soldiers are getting more and more nervous, "Attention everyone!" Huang Xu looked at the red line printed on the ground, which was a sign line four hundred meters away from the city wall, and waited until the moment when the zombie just stepped on the red line! Huang Xu immediately ordered to fire!

"Suddenly~DadaDa~" In an instant, the city wall was full of fire, and bullets were accurately shot into the heads of zombies, and the zombies whose brainwaves were destroyed no longer had the strength to support their bodies and fell, and then they were cruelly trampled by their companions and turned into a mess of flesh! With the passage of time, the loss of the zombie army is getting bigger and bigger, although the soldiers on the city wall have strong firepower, but the zombie army's crowd tactics are still slightly better, even if the zombie army is still in a state of advancement, after more than an hour of hard work, the zombie army finally advanced to the bottom of the city wall, and was not afraid in the face of the city wall that was more than 20 meters high, and began to build a human wall!

"Stop them, everyone!" The soldiers on the city wall immediately shot at the zombies who were building the human wall, and even this could not stop the zombies, after all, the corpses of their companions were also a good stepping stone!

Inside the fortress, the death squad led by Lieutenant Tian Jie was also ready, "Are you ready?" ”

"Ready!"

"Let's go!" Lieutenant Tian Jie gave an order, and the death squad immediately set off, and along the drainage pipe, the four death squad members came to the outside of the city wall with heavy weapons that could kill the director!

On the city wall, the soldiers are still fighting bravely, the corpse wall is getting higher and higher, the soldiers look at the corpse wall, a little desperate, but still keep firing downward, then the sky suddenly darkened, and the soldiers looked up at the terrifying zombie birds! You must know that this zombie bird likes to eat carrion, and the zombie army just attracts them! But compared to the rotten flesh, the zombie bird prefers fresh human flesh, you must know that the zombie bird generally does not act alone, generally appears in groups, every time the zombie bird encounters, the entire sky will be covered by a piece of black pressure, covering the sky and the sun!

"There's a zombie bird! Be careful, everyone! ”

"Suddenly~Dada~" Many soldiers turned the direction of their guns and attacked the zombie birds upward, and the speed of building the zombie wall was accelerated due to the halving of the firepower!

"Pyro! Where's the Pyro! Huang Xu shouted the flamethrower, the zombie birds in the sky are constantly hovering in the sky, the bullets are not very depleted to them, and they will also cause a lot of waste, and the flamethrower is a sharp weapon against the zombie birds, you must know that once the fire is sprayed with combustibles, it is easy to spread, the zombie birds appear in groups, and the flamethrower is simply a disaster for them!

The flamethrower came to the city wall with a flamethrower on his back, looked at the zombie bird in the sky, raised the flamethrower to the sky is a random spray, the zombie bird was lit immediately when it touched the flame, due to the huge density, one was lit and even a few nearby ones would be lit, due to the addition of the flamethrower, the threat of the zombie bird gradually decreased, and the pressure on the soldiers who fought the zombies on the city wall was also less, in the command center, General Yang Hua looked at the huge display screen and observed the changes on the battlefield! And inside Yi Xuan's base, everything that happened in the Xi'an fortress was also being monitored, and at the same time, Lieutenant Tian Jie was getting closer and closer to their target...

¹: Barrett M82A1, produced in 1982, designed by Lonnie Barrett, can fire 12.7mm caliber bullets, can fire multi-functional bullets, is so powerful that it can easily penetrate the armor guard, but it is too large and has too much smoke after shooting to make it too useful on the battlefield!
