"Suddenly~Dada~" Bullets poured down on the city wall, forming a golden ocean, and their opponents were living dead, under the duel between the black ocean and the golden ocean, after the zombies paid a huge sacrifice, after all, the black ocean was pushed under the city wall, and the soldiers began to shoot frantically at the zombies under the city wall, and the zombies were also crazy about building the human wall, however, for building the human wall, Ah Yong They had already prepared, when reinforcing the city wall, Ah Yong asked Uncle Four-Eyed to design a device, The device is full of lubricating oil, and the lubricating oil is released instantly when the zombies build the human wall, making the city wall extremely smooth, and the zombies can't grasp the city wall to build the human wall, so they can only rely on stepping on the corpses of their companions to go up a little bit, although they can also raise the height, but this is too slow and has to pay a huge price, tens of thousands of zombies will be killed every meter of upward advancement, as the corpse wall gets higher and higher, the original base begins to be unstable, Many zombies crawled halfway and suddenly fell down because their claws were stained with the blood of their companions, "Director, when will this corpse wall be built?" Yang Dong, who was standing in the distance, couldn't sit still while watching the efficiency of the zombies slowly, three hours had passed since the battle, but the corpse wall had only been built more than thirty meters, and the wall of the Sky City was eighty meters high, which was a lot worse, and the casualties on the zombie side were also very heavy, at least one million zombies had died under the city wall, and the soldiers on the city wall had already killed red eyes, many soldiers' gun barrels were red but they were still pulling the trigger, and the logistics department was also busy, and it would be used up in a few minutes after sending a box of ammunition, The soldiers of the logistics department complained bitterly, but for the fortress, for the sake of their families, they fought, Ah Yong, who had been standing on the city wall to command, looked at the consumption rate of ammunition, and began to worry a little, now it is basically the logistics department to send up a box almost used up before sending the next box, this is the early battle, in the later stage, everyone is going to rest, this speed can't catch up with the speed of consumption, hundreds of millions of zombies, how to fight!

Ah Yong was worried at the same time, Leng Ying was also worried, although she was not on the front line, but she saw the battle on the front line through the monitoring of the fortress, now, although the arsenal is still rushing to work, but their daily production may not be able to support the soldiers to fight all morning, Leng Ying couldn't sit still, she quickly contacted Ah Yong, "Ah Yong! Tell the soldiers to save some bullets, if this continues, we simply won't have enough ammunition to support in the later stage! ”

"Got it!" Ah Yong replied lightly, he looked at the soldiers who killed the red eyes and didn't know if he could make them stop, but he still picked up the loudspeaker, "Soldiers, don't shoot in a hurry, aim and then fight, we try to save ammunition, we only have enough to fight this battle, if they have reinforcements, we will run out of ammunition!" And the people in the logistics department are very hard, and their speed is almost unable to keep up with the speed of your consumption! Let's save a little ammo! So as not to leave a legacy behind! After Ah Yong's words, the soldiers did not disappoint him, the ammunition consumption was reduced, everyone changed from strafing to point shooting, and the accuracy of the point shooting was very high, only when the point could not come, everyone strafed the zombies, which greatly reduced the ammunition consumption!

"Xu Ya! Xu Ya! Location 022,334, find a smart zombie! Xu Ya! ”

"Phew!" A super-large caliber armor-piercing bullet was fired from Xu Ya's sniper rifle, and a fire-breathing zombie with intelligence was killed on the spot, "Report, the target is killed!" ”

"Good! Xu Ya! Wait for the next instruction! Leng Ying looked at the surveillance in the command center and said, "Xu Ya understands! "It turns out that Leng Ying trained a sniper team separately for this zombie attack, they are different from Hawkeye's sniper team, they only fight high-level mutant zombies and intelligent zombies, they all use specially modified sniper rifles, short life, special ammunition, it is difficult to make, so, the entire team is only three people, led by Xu Ya, in order to facilitate the battle, a week before the siege began, Leng Ying turned the area of ten kilometers of Sky City into coordinates, which is convenient for accurate positioning!

"Tang Yu! Tang Yu! Direction 034,559, Demon Zombie, Hold Down! ”

"Tang Yu understands!"

"Phew! Bang! "The speed of the demon zombie is really fast, Tang Yu's first shot was dodged by her, but fortunately, Tang Yu reacted and quickly made up for her before sniping her headshot!

"Roar!" Seeing that his generals were named one by one, the director was angry, he yelled, all the high-level mutant zombies quickly surrounded the wisdom zombies, and the wisdom zombies no longer rushed forward so aggressively, but honestly stayed behind, let those ordinary mutant zombies go to the front to block the bullets, this sniper, a total of five wisdom zombies were sniped, Xu Ya and Tang Yu were two each, and another member sniped another wisdom zombie, although the record was good, but Tang Yu and Xu Ya were seriously injured, although this sniper rifle was very powerful, But the recoil is also very damaging to people, Xu Ya and Tang Yu's shoulders are purple, and their eyes are swollen because of the sniper scope, "Can you still fight?" ”

"No problem, at least ten more can be killed!"

"Xu Ya! Don't force it, the recoil will break your bones, and I'll give you the task evenly! I ask you to retreat, and you will retreat! ”

"Understood!" The position of the three snipers is the best in the entire Sky City, and the other snipers are sniping mutant zombies at the ordinary commanding heights, Leng Ying watched the battle of everyone in the command center, looking at the faces of those soldiers, and couldn't help but feel a sense of awe in her heart...
