Chapter 979

However, the slave workers didn't build it to stop them. They just wanted to create a buffer.

For example, when the infected body group rushes forward, the speed is very fast, and the impact force generated is likely to directly knock down the sentry tower and firepower guard.

But with the presence of buffer belts, the infected bodies must slow down and crawl slowly, or they will be knocked down.

As long as they slow down, it will be very difficult to get up again soon. Virtually, it is equivalent to well protecting the defense facilities around Xifeng fortress.

But through a small buffer zone can solve the big problem, for the whole Xifeng fortress is undoubtedly very profitable.

Of course, these ideas are based on the fact that the canopy is broken by the infected population.

Because at this time, all the defense facilities are wrapped by the sky curtain. As long as the sky curtain is not broken, the infected body can not touch any defense facilities. The slave workers are just preparing for everything.

Perhaps it was not enough. In order to delay the attack of the infected group to the greatest extent, the slave workers cooperated with the ground digging sand worms to dig many pits, large and small, around the canopy of the sky.

The small pits are 10 meters wide and 5 meters deep. The large ones are even 50 meters wide and 10 meters deep, and there are hundreds of them.

There was no cover on the surface of the pit, not even some turf or leaves.

If you use traps to describe these pits, it may not be appropriate, because the traps are relatively hidden.

There are dozens of pits in the open pit.

As for why we should do this, the reasons are very simple. First, the pit is too big, and it will be very difficult to cover it with normal methods.

Second, the time of slave workers is limited. They have too many things to make, so they can only dig holes. There is no time to cover them up

However, these pits can also play their due effect, because the ground outside Xifeng fortress is so wide that the infected body group must step in if they want to attack.

If they choose to walk around the pit, Xifeng fortress would prefer to see it. After all, the attack and impact of the infected body group will be greatly reduced.

If you use the life of the infected body to fill the pit, Xifeng fortress can accept it. Anyway, the purpose of digging a pit is to deal with these infected bodies. One can "pit" one by one.

This is all the defense facilities of Xifeng fortress, whether it is attack or defense or trap.

It's no exaggeration to say that even if no one defends Xifeng fortress at this time, these defense facilities alone can stop 500000 infectious agents, or even more.

Of course, this time, the road army and others must be there, and they have made full preparations and arranged their formation.

At the edge of the sky, the wolf cavalry were all standing there riding frost wolves.

They are more than 10000 in number, holding two bone axes produced by Xifeng fortress. They have a strong sense of killing.

It's more convenient to cut than the skeleton of the cavalry. It's three times as big as the axe of the cavalry.

Although this kind of axe has no energy, it is sharp and even ancient, which makes people feel that it is not strong enough.

But in fact, the bone axe has been heavily forged and has a little Rune blessing. It is much sharper and more durable than the energy axe.

On the left and right sides of the wolf cavalry regiment stood the Triceratops and the cephalograms, which added up to nearly 10000.

They are the most suitable for charging among the dinosaurs currently owned by the road army. They have great lethality in sprint.

Therefore, they and the wolf cavalry formed the first echelon of Xifeng fortress as a whole, referred to as the Stormtrooper.

The task is to carry out the first wave of charge after the infectious body group approaches, in order to limit the impact force of the infected body group, and let the infected body group slowly approach the sky curtain.

Although it is very dangerous to enter the infected population through the protection of the canopy, they will not rush out very far, and will return in time after reaching the goal, which greatly reduces the risk coefficient.

Behind the first echelon, there is a second echelon, consisting of onychosaurus, raptor Utah, and monopterosaurus, with a population of 12000.

They are characterized by rough skin and thick flesh, strong melee ability, able to withstand the impact of ordinary infected body, and they will not be threatened.

The task is to act as the front row, in order to wait for the infected body group to meet behind the scenes and receive the returning stormtroopers.

The first means that they will not follow the protective echelon.

The third tier is composed of troll hunters and Flamingo raptors, which add up to nearly 10000.

They have a common feature is that they can use long-range attack, and the attack power is not bad, can kill the infected body below the s level.
