No way, compared to the zombies on the ground, those flying zombies are undoubtedly the most difficult to defend, and the griffin knights in the pet beast army are only 10,000 when they are full.

And the number of flying zombies will definitely be ten times and dozens of times that of the griffin knight, even if the quality of the flying zombies is uneven, but they have an absolute advantage in quantity, it is still easy to break through the blockade of the griffin knight.

If you don't hide at home, maybe before all the zombies outside the city are killed, all the evolutionaries in the city will become zombies.

Although the scene of the previous massacre had already been cleaned up, the strong smell of blood could still be clearly seen.

Although it was a little cruel, it has to be said that Wang Dong's goal of killing chickens and monkeys was achieved, and as soon as the order was issued, no evolutionary dared to disobey this order.

Didn't you see that more than 100,000 people said to kill them? If you really dare to disobey, people won't care about one or two more.

So after Wang Dong gave the order, no one dared to resist, no one even dared to go out on the street, and they all hid at home. This is not because he is afraid of Wang Dong's slaughter, but because he is afraid of zombies.

They are all elites from various bases, of course, they have more or less seen the corpse tide, and they know that there are many flying zombies in the corpse tide.

What's more, in such a large-scale corpse tide this time, there are definitely a lot of flying zombies. For the safety of your own life, it is better to hide at home.

If it's a reinforced concrete building, it's really not a good choice to hide at home, but the buildings in Sky City are all metal and very strong.

Not to mention the mid-level zombies, even the high-level zombies can't be broken. Only top-tier zombies can be easily broken.

However, if they are really killed by the top zombies, then they can only be considered unlucky.

Of course, although everyone is hiding at home, it doesn't mean that they don't want to see how Sky City fights, so many residents living in the upper floors are looking out of the windows and quietly waiting for the arrival of the corpse tide.

Wang Dong set up a total of four lines of defense this time, the first line of defense was from under the city wall, all the way to the small holes scattered in it twenty kilometers away, these holes one meter deep, thicker than the thighs of low-level zombies, there were tens of millions.

Secondly, the second line of defense is the automatic defensive weapons in the base, the arrow tower and the energy cannon, the attack distance of these two defensive weapons is very long, the range of the energy cannon with the fourth-level crystal core as energy is about one thousand meters, and the sixth-level crystal nucleus can increase to 1,500 meters.

The range of the advanced is even farther, and as the level increases, for example, the high-level energy cannon with the ninth-level crystal nucleus as energy can attack targets up to 3,000 meters away.

The attack range of the turret is farther than that of the energy cannon, and the range of the same energy level is 1.5 times that of the energy cannon.

The last time I got so many materials, basically half of them were made into crossbow arrows of the corresponding level by Wang Dong.

There are a lot of crossbow arrows below level six, there are millions, that is, there are hundreds of thousands of crossbow arrows at level six, and this is not counting high-level crossbow arrows.

If so many crossbow arrows are used to kill low-level zombies, each of the four or five level crossbow arrows shot by the intermediate arrow tower is enough to penetrate hundreds of low-level zombies, and it will become weak.

Like a sixth-level crossbow arrow, it can completely penetrate hundreds of low-level zombies. Of course, penetration is penetration, but it is not killing. If you want to kill zombies, you have to destroy your brain.

It's simple to destroy the brain of a zombie with a crossbow arrow, but to destroy hundreds of them, it can't be said to be difficult, but impossible.

But Wang Dong didn't care, because he didn't plan to use these arrow towers to deal with those low-level zombies, because it was a bit overkill.

The arrow tower is used to deal with those mid-to-high-level zombies, and the best defensive weapon against low-level zombies should be the automatic energy cannon.

Each intermediate crystal nucleus is enough for the intermediate arrow tower to shoot hundreds of crossbow arrows, but one intermediate crystal nucleus can only fire ten shots from the energy cannon.

It seems that the energy cannon is a little uneconomical, but in fact, in terms of the efficiency of killing low-level zombies, the energy cannon is the most suitable.

Then there is the third line of defense, which is a "moat" that surrounds the city in the sky.

Similar to the ancient moat, but in ancient times it was a real river, but the "moat" around the Sky City was not a river, but a deep ravine, or a deep pit.

This pit was twenty meters deep and hundreds of meters wide, and the entire city in the sky was surrounded by this wide and deep pit, except for a part set aside in front of the four gates for passage.

Such a big pit took the entire Beastmaster Legion a day to dig out, if it weren't for the lack of time, Wang Dong really wanted to dig it a hundred meters deep, and there would be no enough zombies to fill it at that time.

In fact, these conventional traps are all standing facilities in other bases, but the establishment time of Sky City is too short, and I didn't expect the corpse tide to come so quickly, so naturally some are not prepared.

The last line of defense was the city wall, and this time the tide of millions of corpses was attacking in the direction of the west, so Wang Dong could only leave a few thousand people on the other three walls to guard.

All the remaining members of the Beastmaster Legion have all come to the western city wall, and tens of thousands of evolutionaries with the lowest strength are level six, which can completely turn Xicheng into a chasm that zombies can never cross.

The first three lines of defense are all consumed by traps and auto-defense weapons, and it is only on the last line of defense that the Evolver is really needed to participate in the defense.

If the last line of defense also fails, Wang Dong can only activate the Sky City and fly high in the sky to avoid this disaster.

However, Wang Dong believes that if he wants to force himself to that role, this few million zombies are not qualified, and maybe tens of millions of zombies may not be qualified, and he is very confident in his pet beast army and beast king army.

...

As the clock ticked by, the Evolvers who were in their own homes, watching through the windows of the city, even though they didn't have to be directly involved in the battle against the zombie tide.

But they knew that if the city guards lost this battle, not only would the Sky City be destroyed, but they would not even think about escaping.

So they looked nervously and expectantly at the zombies outside the city and the city guards on the city wall, and they were silently praying in their hearts.

However, Wang Dong was not like this, he was very calm from beginning to end, and all the people of the pet beast army on the city wall were also calm, and this calmness carried a kind of contempt.

Because there are only millions of zombies, some time ago, when there were only more than 600 pet beasts in the king's hands, and there were only more than 1,000 people in the beast king army, he could pit one or two million zombies.
