Chapter 587 Melee on the ground

The flying mutant creatures were the first to rush into Crystal City.

From a distance, these flying mutated creatures are birds of prey with wingspans exceeding two meters, and some even reach four or five meters.

Fortunately, Xu Xin did not see anything like the pterosaurs among these flying mutant creatures.

From this point of view, there should be no advanced mutant creatures in the herd this time.

At least not yet.

This is good news.

Because they are fully capable of blocking this level of beasts!

"Everyone, pay attention to the sky above. The flying mutated creatures have entered the Crystal City and will be close soon!" Xu Xin said in the group.

The situation on the ground is not optimistic either.

The beast tide that originally surrounded Crystal City on the ground has now completely poured into Crystal City.

In the map in his mind, the part of Crystal City has been completely shrouded in red dots!

Under the siege of such a large group, the more than two hundred survivors in Crystal City were already stretched thin to deal with the creatures on the ground, and they also had to face the beasts that jumped up from time to time to destroy the heavy crossbows.

It is really difficult for them to distract themselves from attacking flying creatures in the sky.

"this……!"

"I may be able to take care of heaven!"

"I will use a heavy crossbow to attack the sky!"

Sure enough, they were a little confused after seeing Xu Xin's words.

Xu Xin immediately said: "Prioritize attacking the ground beasts and clearing out the number of ground beasts! I want you to pay attention to the mutated creatures in the sky and don't let them cause damage to you, the tree house and the heavy crossbow!"

"Understood!"

"I still have half the ammunition! Enough to hold on for a while longer!"

"You used it too fast! I still have more than half of it!"

"Save ammunition! Aim at dense locations to attack, so that every round of ammunition has maximum effect!"

"I'm in charge of this street on the east side! Don't let our bombing ranges overlap!"

"Then I can send out a big bird to attack the sky!"

No need for the members of the Explorers to say anything, this group of survivors spontaneously began to carry out the most effective attack and plan on the herd!

After all, they are the survivors who have survived to this day, and they are the leaders in Area 1 and Area 188. These people have already become veterans in the survival world.

There is no need for them to direct what to do.

The traveling speed of flying mutant creatures is much faster than that of ground mutant creatures, and it is far faster than the speed of underground mutant creatures.

In just these ten seconds, he had already crossed half of the Crystal City and was completely approaching the World Tree.

However, when they flew into Crystal City, a small number of them fell directly.

They are the larger ones among this group of mutated creatures!

"Affected by Crystal City!" Xu Xin immediately thought of the principle and reminded in [Explorer], "These flying mutant creatures are not completely without the blood of giant beasts!"

It seems that the opponent did not find a sufficient number of flying mutant creatures without the blood of giant beasts, so a group of flying creatures with relatively thin blood of giant beasts were mixed into the group.

They may also want to try to see if they will not be affected by Crystal City at high altitude, but unfortunately, according to Afu's test, as long as they can see, they will be affected, and the visual range of raptors is far beyond

Humans and other mammals basically fell in large numbers as soon as they entered the scope of Crystal City.

Within a few seconds after entering Crystal City, the entire flying army was destroyed.

But the remaining flying mutated biota were not affected at all. They came quickly, directly passed the heavy crossbow defense line of two hundred survivors, and swooped towards the World Tree!

Their target is the trunk of the world tree, not the crown.

The tree crown is too lush and too broad, almost covering half of Crystal City. It would be a huge project to completely destroy the tree crown, not to mention that the tree crown can repair itself. The speed of their destruction may not be as fast as that of repair.

speed.

The other party understands very well that only by destroying the trunk can the World Tree be destroyed, and attacking the crown is useless.

As a result, all the flying mutated creatures did not attract the slightest attention to the crown, but flew directly under the crown of the World Tree and swooped towards the trunk.

It's so fast!

At this moment, three raptors suddenly flew out of the window of Wen Guixin's tree house, and flew quickly towards the flying herd!

Just like three fighter jets taking off from the ground, they climbed towards the enemy fighter jets swooping in the sky!

Moreover, their goal is also very simple, which is to hit them!

If you hurt the other party, you will earn it!

The flying mutant creatures did not surround the World Tree like the ground mutant creatures. They flew collectively from the north of Crystal City. The overall formation was like geese flying south, showing a standard herringbone.

This formation is to reduce the overall flight resistance.

Usually the leader is the strongest and the most tired.

The three birds of prey flying out of the window of Wen Guixin's tree house were aiming at the tip of the herringbone formation!

In an instant, three birds of prey crashed into the enemy's flying formation. The entire formation of the flying mutant creatures was directly disrupted. Sharp bird calls sounded and feathers flew around!

Among the group of explorers, Wen Guixin spoke up: "What are you doing standing there in a daze? Hurry and blast them!"

As she spoke, the treehouse repeating crossbow on her treehouse began to exert its power, scattering dozens of explosive crossbow bolts into the air in an instant!

At the same time, explosive crossbow bolts were also scattered from several other tree houses!

To deal with targets in the air, use heavy crossbows. Super-heavy crossbows are meaningless. Explosive crossbow bolts are the most suitable!

But the mutated raptor is very flexible in the air, and it is not that simple to hit it.

Most of the explosive crossbow bolts were dodged by the mutated raptors in the air and landed among the mutated biological groups on the ground.

And under the coverage of the exploding crossbow bolts all over the sky, a small number of them directly hit the mutated raptor in the air!

"Boom boom boom boom boom!"

The double explosions on the ground and in the air caused the surroundings of the World Tree to be instantly illuminated by fire extremely brightly!

For a moment, it seemed like fireworks were being set off under the World Tree, accompanied by feathers all over the sky, and it was even a bit beautiful.

The mutated raptor affected by the air explosion fell off from the air in large pieces.

But there were still some parts that were not affected. They completely ignored the others and rushed towards the World Tree at extremely fast speeds!

Then it passed over the trunk of the World Tree, and its sharp claws were like sharp knives, scraping across the trunk of the World Tree!

“Boo——————!”

Such sounds kept coming to Xu Xin's ears!

Every raptor leaves a mark several meters long and half a foot deep on the trunk of the World Tree!

For a time, the trunk of the World Tree was riddled with holes!

Fortunately, the entire trunk is a full ten meters in diameter, and even the mark half a foot deep has not penetrated the bark of the world tree.

However, the raptors that passed over the trunk of the World Tree and caused considerable damage to the World Tree drew a circle in the air and turned back to swoop towards the trunk of the World Tree again!

"嗗————!"

"嗗————!"

In an instant, around the trunk of the World Tree, countless raptors were like flies surrounding rotten fruit, flying back and forth crazily. Each flight would cause scratches of several meters on the trunk of the World Tree!

Moreover, they actually started to attack a certain location very disciplinedly.

Within a few seconds, the target location was struck more than a dozen times, forming a ravine that was four to five meters long, more than ten centimeters wide, and a foot deep!

If this continues, no matter how thick and rough the World Tree is, it will still be unable to withstand it!

The explorer members around World Tree began to hesitate when they pointed at the control panel.

This group of mutated raptors is too close to the trunk of the World Tree. If they were shot through, I am afraid it would cause even greater damage to the World Tree!

It is simply a thousand injuries to the enemy and a thousand losses to oneself!

Fortunately, before they could think of a better way, in the blink of an eye, the heart of the plant came into play.

Under the influence of the World Tree, the height that the vines controlled by the heart of the plant can attack has increased several times!

The original heart vines of the plant were only ten meters long at most, but now, they stab straight into the sky twenty or thirty meters high!

Countless vines emerged from the ground, like a bamboo forest rising from the ground, directly piercing half of the flying raptors flying in the air!

In addition, the vines are extremely flexible. Being pierced through the air, the number of mutated raptors was instantly reduced by nearly half again.

Under this crisis, the remaining raptors no longer focused on attacking the trunk of the tree house, but screamed and climbed rapidly!

Originally, they chose to attack nearly thirty meters above the ground, but now, in order to avoid the attacks of plant vines, they had to fly to higher areas.
