Guo Haonan does have understanding, and with Yang Chen's guidance, the two of them have successfully resolved many crises. And Guo Haonan can always find the sudden backstab or corrosive fluid in advance, once Yang Chen curiously asked him what he was doing in school, and he replied that in addition to class, he was also the main force of the school's tennis team. Yang Chen was relieved.

With the cooperation of Yang Chen and Guo Haonan, the casualties of this machine gun position plummeted, but the other machine gun positions were not so ideal. In just three days, the twenty people who were supplemented with Guo Haonan are now left with Guo Haonan. And Yang Chen's group of people, there are only three left: him and Che Xun Tianyu.

As usual, after Yang Chen fought for 6 hours, he dragged his tired body to the lounge, but as soon as he entered the door, he heard a rapid alarm in the room.

"Old horse? What's going on? Yang Chen ran out of the lounge and asked Ma Shan nervously. This warning light will not go off unless there are special circumstances.

"Yang Chen, it was said that there were zombie birds outside, be careful."

"Zombie birds?"

Yang Chen's heart tightened, and he remembered the overwhelming scene he saw when he fled. And it's just a zombie bird in Luzhou City, and now there are definitely more zombie birds outside Chengdu than there were at the beginning.

The gunfire in the room stopped for a while, and several people sent a dozen or so steel wire nets similar to anti-theft windows, and Ma Shan and a group of people took hammers and nails to nail the steel wire mesh to the firing port, leaving only a fist-sized hole for the muzzle to stick out, and the rest of the place was full of thumb-sized mesh holes.

I don't know if this steel wire mesh will work, if it is an ordinary bird before the end of the world, even an eagle can't get in. But right now, no one can say.

Liu Tongyu, who was on the top floor, looked at a zombie bird in the distance through the scope, and his whole face was gloomy and terrifying. The large flock of zombie birds in the sky, at least millions, are still gathering. Although it has not yet entered the battle, it is conceivable that once the zombies begin to join the army of zombies besieging the city, the entire battle line is very likely to be breached.

Liu Tongyu sighed slightly, and a sense of powerlessness suddenly appeared in his heart. After so many days, there are heavy human casualties, more than 30,000 soldiers are killed every day, and many more civilians are injured by mistake. But the zombies outside the city did not decrease at all. A large number of young and middle-aged people have been transferred to the army, and now there are more than 10 million old and weak people left in Chengdu City, and the people's hearts have long been scattered, and everyone is looking forward to retreating.

"Bang bang bang ~~!!"

The sky where the zombie bird was located suddenly burst into black smoke, and Ouyang Tiankuo knew that it was the air defense gun's anti-aircraft cannon that fired. With the firing of tens of thousands of large and small anti-aircraft guns. The zombie birds in the distance rained down. After all, if bird zombies want to fly, their bodies must maintain a light weight, which is not as exaggerated as the mutant zombies on the ground.

"Quack~!!"

As the humans fired first, the zombie bird attack began! Countless zombie birds, large and small, flew towards the city wall.

"Old horse! What to do? ”

Looking at the black sky outside the shooting hole, Yang Chen asked Ma Shan next to him with a pale face.

"What to do? I don't know. No matter, fight the zombie birds! We have enough shooting here. Shoot!! ”

Ma Shan adjusted the angle of the machine gun and pulled the trigger on the zombie birds that could not be seen through at a glance, and Yang Chen and the others also learned the same and aimed the machine gun at the zombie birds in the sky.

It can be said that the firepower on the entire Chengdu city wall is quite intensive, with an average of more than 3 machine guns blocking per meter, but there are too many zombie birds, and the number is almost tens of millions. And not all of them flew towards the city wall, a large part of them flew into the city of Chengdu and launched an attack on the crowd that appeared on the street.

"Jingle bell~~!!"

Supplies and ammunition arrived, and Che Xun hurriedly opened the gate.

One soldier said to the man outside the door, "Hurry up and bring in the individual soldier cloud burst bombs." Hurry up!! Seventeen or eighteen people outside the door, carrying seven or eight suitcases, trotted into room 311.

"Type 97 93mm Individual Soldier Cloud Burst Bomb!" Ma Shan, who was next to him, was overjoyed when he saw the things he moved in. Give the machine gun to one of the fighters next to you. Picked up a launch tube, picked up a cloud burst bomb from the box, skillfully loaded it into the launch tube, and then ran to the observation window, aimed at the zombie bird outside and pulled the launch trigger.

"Whoosh!"

A cloud of white smoke rose in the room, and then the cloudburst bomb quickly flew more than a hundred meters away, and then exploded entirely. Suddenly, a ball of fire with a diameter of more than ten meters rose from the zombie birds in the sky. At least a thousand zombie birds fell to the ground with flames all over their bodies.

"Sure enough! Che Xun, what are you doing in a daze, carry the cannonballs for me! ”

"Hey!"

Che Xun and another man moved a box of cloudburst shells to Ma Shan's side, and the latter fired cloudburst shells outward at a rate of 3 rounds per minute. And the rest of the city wall also began to spit out streaks of white smoke, and in just a few minutes, a flaming city wall was formed outside the city of Chengdu.

The zombie bird's offensive was contained at once.

"Roar~!!"

There was another huge zombie roar, the zombie birds in the sky, and the countless zombies on the ground, hearing this sound, slowly retreated. The zombie army, which had been attacking the Chengdu city wall for more than 20 days, finally retreated again.

"His grandmother's, the zombies have finally retreated!"

Ma Shan excitedly put down the launcher on his shoulder and said to the soldiers around him: "Put down the baffle and rest." ”

After listening to Ma Shan's words, Yang Chen put down the machine gun, lit it with a cigarette per person

At the same time, General Zhao, the top commander of the Chengdu military government, and the commander-in-chief of the four city walls, were arguing in the large conference room of the military government. There was no one next to them, and there were only five of them in the huge conference room. It can be seen that this meeting is quite important.

"I disagree! There are still so many people in the city, how can you say give up and give up!! Guan Tao patted the table and stood up.

"Lao Guan! Calm down! Isn't that a discussion? General Zhao pulled Guan Tao and sat down.

"Everyone knows the situation now. We're basically running out of ammunition. Only 3 of the nineteen large arsenals in reserve remained, and if they had fought like yesterday's, they would have lasted 7 days at most. And now there are a lot of zombie birds in the city, and the transport force alone has lost more than 100,000 people today, and the zombie birds in the city are not wiped out, and the transport troops will not be able to transport ammunition. Besides, there are more and more zombies outside, we are surrounded on three sides, if it weren't for the Yangtze River in the north, our Chengdu City would be a dead city now. I propose that Chengdu be evacuated as soon as possible. ”

"How to withdraw? By those little steamers, or by the hundreds of trains. There are more than 10 million people in Chengdu. Guan Tao glared again.

"I propose to open the Chengdu Bridge and let the refugees out of the city. Now we have less than 200,000 people a day, and these more than 10 million people still have more than 2 million troops, and we can't withdraw in two months, but can we hold out for two months? Let them stay in the city sooner or later, and if they are let out of the city, although there is danger, at least there is a chance to survive. "It was General Bai Rongshang, the commander-in-chief of the southern city wall, who spoke.

There was silence in the conference room for a moment, the way Bai Rong said was the only way now, although there were a large number of zombies north of the Yangtze River, but there were definitely fewer than those on the south bank. Moreover, the Yangtze River Bridge east of Chengdu has all been blown up, and the zombies in the south will not move to the north.

"Vote" General Zhao finished smoking a cigarette and said silently: "If you agree with General Bai's proposal, please raise your hand." After speaking, General Zhao was the first to raise his hand, and then the commanders of the west, south, and north city walls also raised their hands one after another, only Guan Tao was silent.

"Majority passed." General Zhao glanced at Guan Tao, paused, and then said, "Everyone, it's not that we are greedy for life and afraid of death. Our Chengdu base bears most of the zombie attacks in the southwest region, where the Chinese population is the most dense, and 30 nuclear bomb explosion cities, 17 in the southwest region alone, more than 40% of the mutated zombies are under the city of Chengdu. And we have a lot of materials and equipment in each base, and we did our best! I will report the situation of this meeting to the Central Committee. Everyone go down and prepare. From today I will detain all the transports and at the same time request the support of the Yangtze River Fleet, which should be able to transport 1 million troops at a time. I will use all the armored vehicles for transporting ammunition until all the front-line arsenals are saturated. Hopefully, the army at the front will hold out for another 7 days. The refugees in the city will be evacuated from now on, and in about 7 days, they will be able to evacuate, and we will all evacuate after the refugees have been evacuated. Meeting. ”

"Wait, we now have more than 2 million troops, and only 1 million can retreat to Wuhan. You go, give me all the armored vehicles, tanks and the remaining supplies in the city, and I will take the remaining 100 troops to cover the refugees across the river. That's it! After Guan Tao finished speaking, put on his hat and left the conference room without looking back, leaving only a few sighs behind him.

Yang Chen didn't know what happened in the conference room, and they were still asleep. In the Xiaguan District and Luoye District of Chengdu City, groups of soldiers have already driven in. They first blocked the access of the two districts to the rest of the district, and then began to notify each household of the junta's decision.

More than an hour later, the refugees with their families slowly left under the watchful eye of the army. Even though they are extremely reluctant in their hearts, the military government is about to abandon the city of Chengdu, and it is impossible to leave it, and it is definitely a death to stay, and there is still a glimmer of life after crossing the Yangtze River.

Under the strict orders of the roadside troops, there was basically no sound in the retreating crowd, except for the sound of footsteps and the occasional cough. Even when zombie birds attacked the migrating population, soldiers soon came and pulled the wounded away. Their fate is unknown.

More than 3 million people, one south and one north, were divided into three roads, and slowly retreated to the north bank of the Yangtze River from the three intersections of Chengdu Bridge, Sanqiao Expressway and Chengdu Yangtze River Tunnel. Then disperse to a vast area north of the Yangtze River. Most people crossed the river and walked west along the Yangtze River, but many people found a few hidden places nearby and took refuge.

After they finished retreating, they were followed by several other gathering places such as the Drum District and the Baixia District. And all this is going on in an orderly manner, but no one knows what kind of fate these people will have after crossing the Yangtze River. Not only them, but the whole world has changed dramatically today, who knows what their fate will be tomorrow?

"Continue tonight!!"
