The huge black metal iron wheel rumbled outside the city wall outside the base, overwhelming and flattening the zombies who were surrounded outside the base. A sentence suddenly popped up in Luo Xun's heart - the gears of fate have begun to turn...... Well, this sentence doesn't go well, in every sense of the word.

Luo Xun and some other people who have no abilities are responsible for protecting the safety of the three metal abilities, including Yan Fei, Luo Xun, Zhang Quan, and the last one is actually Captain Guo himself, each of whom carries a metal shield that is not small in size, and is responsible for taking care of a metal ability. They also carried towels, water, weapons, crystal nuclei and other things with them, and several earth-based powerhouses were responsible for dealing with the ground outside near the side of the wall at the back of the team, so as not to be crushed by the metal and cause any problems on the ground.

The fire-type supernatural personnel mobilized by the military are responsible for guarding and defending, so as not to be accidentally injured by stray bullets thrown from under the base.

After a lap, a little rest, all the members of the grinding team began to prepare for a new round of battle, at this time the sky was already slightly dark, the time was close to about six o'clock in the afternoon, a soldier in charge of guarding the distance suddenly reminded loudly: "Attention! Air Raid Warning!! ”

Everyone who was about to set off again stopped moving, and their eyes couldn't help but look into the distance. I saw a small black dot flying up in the dense group of zombies......

"These damn broken birds!" Everyone couldn't help but curse in a low voice, staring at the zombie birds that were approaching with solemn eyes.

"It's not just birds...... It seems that there are also wind zombies! Luo Xun pointed sharply in the air and shouted, everyone hurriedly looked carefully, and sure enough, they saw a wind-type zombie with cyan wings sandwiched in the flock of birds!

"No, it won't! Wind zombies can really fly?! "In the past two days, we have hit the crystal nucleus of some fourth-level wind zombies, and there are also some fourth-level wind abilities in the base, but these fourth-level wind abilities have not really expanded their flight ability after upgrading, at most they have increased a lot of time in the air, and they can "float" in mid-air for a small formation after borrowing. It's completely impossible to fly in mid-air like these wind zombies!

"Attention units! Kill as many zombie birds as you can! "The sound of the loudspeakers sounded again, these horns were installed on the top of the city wall, and there were usually defensive teams patrolling from time to time, so that they did not disappear like the horns in the base.

After hearing the voice, everyone raised their spirits, some of them continued to shoot the zombies under the city wall, and the other part of the people with better marksmanship stared at the air - you must know that these zombie birds are very ghostly, perhaps because the zombie birds in the previous attack on the base ended in failure, so they reminded the zombies on the periphery of the base, they did not rashly start the encirclement and suppression of the base during the day, but chose to launch an air attack in the dark at night. Make it impossible for defenders on the ground to target them.

Everyone had to take advantage of the fact that there was still some light in the sky and try to kill one head!

Gunshots rang out throughout the wall, and at least half of the people on the wall took aim in the air, and some of them had guns, and some of them directly used their abilities.

The vanguard came under the first attack as it approached the city walls, and although some of them were hit, the rest immediately moved up, circled overhead, and flew back.

Everyone's eyes were fixed on the place where the zombies had disappeared, for fear that they would come again.

Sure enough, it didn't take long for the second wave of flying zombies to take off again!

"What's in front of them? I hit it! ”

"Something has fallen!"

"Oops, stone!"

"Roots, glass! They're throwing garbage! ”

Throwing abilities is too mentally draining, and the mental power of many zombies will also affect their flight status, and the zombies who seem to have charged their IQ in advance tonight did not choose to fly above everyone's heads to throw their abilities, but picked up some bricks and stones everywhere and threw them on the city wall!

Defensive shields, shields, and ability shields were erected, and everyone was confused by this round of air raids. And at this time, the zombies below also started a new round of attacks!

A group of giant physique zombies three or four meters tall suddenly broke through the many short zombies, and every time they stepped on the mountain, they made a loud rumbling sound and ran towards the city wall step by step!

When the giant zombies arrived, they slammed their shoulders into the city walls!

"Ahh

"Help!"

"Ahh

"Falling, falling!!"

Some of the people standing on the edge of the city wall actually fell under the city wall because of this, and one of them accidentally fell under the city wall! In just a few seconds, these people who had just fallen were completely split by the crazy zombies below and became skeletons, and they didn't even have time to transform into zombies!!

And eight out of ten|9 of these accidental falls are all people who are standing close to the outer wall with their heads up, paying attention to the zombies in the sky above and preparing to shoot or dodge the "air raid"!

"Damn it!" Seeing that those zombies actually squatted down on the spot after hitting the wall, and let the zombies who caught up behind them step on them and climb up, the faces of the people who found this situation were green, and they hurriedly shouted to the people nearby.

"Quick! They can't be allowed to climb up ladders! "Although the wall is tall enough, if these zombies are bent on climbing up, they really can't stop them.

Captain Guo stood up and just said this sentence when he heard someone shouting: "The soil, the land is moving!" There are earth-based zombies building an earthen ladder outside!! ”

"Damn! Don't let people live! "Hate the hammer wall, several people in charge of monitoring the condition of the city wall hurriedly contacted their superiors.

"Earth-based Adepts! Quickly tune the earth-based ability to the wall! Zombies outside the city walls are building ladders out of earth! ”

Zombie ladders, dirt ladders, and even some directions even tried to directly lift the metal wall and drill into it while Yan Fei was away......

The battle at the wall was a mess, and everyone who experienced this defensive battle was deeply jealous and frightened from the bottom of their hearts, and although no one said it, almost everyone guessed the same possibility - among the zombies...... There must be a person who has wisdom and coordinates the battle situation! It doesn't matter what type of zombie it is, it's not even a zombie at all...... In any case, they can only try their best to see the trick now, even if they know that it is in vain, they must guard as much as possible for a minute, or only a second......

Because, if they don't, in the next second they will probably be unable to breathe, lose consciousness, and become one of those walking dead.

"Remember the three locations I just mentioned?" Luo Xun and a few metal powerhouses were crouching in a corner of the city wall, telling them something. Seeing that all three of them nodded, Luo Xun stood up, "That's it, each of the three people is responsible for a section, and Yan Fei and I are responsible for a section of the east and the north and south city walls, everyone be careful!" ”

"Don't worry, you have to be careful, don't get too close to the edge of the wall." The other two metal-based abilities nodded, one ran quickly to the south and the other to the north, and the person responsible for protecting their safety also hurriedly followed, Luo Xunyou said to the other few people who also followed the metal-based powerhouse team to act on the earth and fire powers: "The military will definitely support the powerhouses of the same family as you in a while, you don't have to worry about anything else, follow the metal-based powerhouses you are responsible for, guard the walls you want to defend, and ensure that the metal wheels can operate normally, and don't worry about anything else!" ”

After saying that, some of them also ran in two directions, chasing the metal powerhouse who had just left.

Three metal giant wheels appeared in three different locations outside the walls of the base, and the rumbling sound sounded in the three directions of the base, rolling and crushing in different directions.

Luo Xun just learned that although Sun Shaoyang and Xiao Li have not yet reached the fourth level, they have already reached the edge of the fourth level, and at this time they can actually control a metal giant wheel by themselves, although the operation will definitely be a little unstable, but at this time, it is better for the three of them to simply divide into three teams, and cooperate with the earth powerhouses who are about to arrive to deal with the zombies around the base as much as possible.

As for the zombie birds...... Captain Guo had just forcibly snatched a few earth-type and wind-type abilities from other teams, and was responsible for protecting their safety all the way, guarding against unexpected surprises falling from the sky at any time.

And Luo Xun here, in addition to the metal shield he was carrying, also called Zhang Su, who had been resting all day, over, although Li Tie and they also need someone to protect them, but with Xu Mei and a few people following them, there should be no accidents for the time being, and there is still a period of time before they go to defend the city wall, so Zhang Su will use it for them first.

Yan Fei once again evenly "uncovered" some metal from the city wall to make a huge metal wheel - the wheel they made before was taken away by Xiao Li, who had the lowest mental power among the three, and Yan Fei and Sun Shaoyang both needed to make another one temporarily.

Huge metal wheels soon appeared on the edge of the city walls, and the rumbling sound sounded again. Zhang Su had already relied on the blessing of his wind ability at this time, and quickly came to the edge of the city wall, he didn't need to call to find out where the two were, he could find all the way by listening to the rumbling sound.

When he saw the two figures, it happened to be when a new army of zombie birds attacked, and their claws still carried all kinds of garbage brought from the abandoned city in a mess, and once they flew over the city wall, they began to throw garbage downward.

But there seemed to be something wrong with the garbage this time, the tiny piles that seemed to have been scattered from the zombie birds, and each one seemed to have a pair of scarlet spots of light on it...... Wait a minute! "Zombie Rat!! Zombie Bird is airdropping zombie rats!! ”
