Not long after the intermediate arrow tower was raised, they began to exert their might, and this was also the first time that everyone, including Yuan Sheng, had seen the arrow tower exert power, and they had never seen it before.

Collapse Collapse ...

A series of voices sounded, and crossbow arrows several meters long were shot out angrily, and the attack distance of the intermediate arrow tower was already very far, almost two thousand meters.

One by one, sharp arrows pierced the sky, and with a terrible sound that broke through the sky, a sonic boom cloud was struck, turning into white light and directly piercing into the fourth-level evolution beast in the front row of the beast tide.

These sharp arrows were incredibly fast, wrapped in a faint amount of energy, and the fur on the fourth-level evolution beasts in the front row could not be stopped at all.

Puff puff ---puff

The last moment the sharp arrow had just been fired, and the next moment the sharp arrow appeared in front of those evolution beasts as if out of thin air, and stabbed into their bodies fiercely.

And that's not all, if the material of the crossbow arrows is made of fourth-level materials, maybe these crossbow arrows powered by one percent of the energy in the fourth-level crystal nucleus can only remain in the body of the fourth-level evolution beast.

It can't be helped, the energy attached is too small, and if it hits the vital point, it can be fatal with one hit, but it's hard to say if it's somewhere else.

But now these crossbow arrows are not made of fourth-level materials, they are all made of sixth-level materials, and they are also produced by smelting furnaces.

Therefore, these sixth-level crossbow arrows launched by the fourth-level crystal nucleus swept in front of the body of the fourth-level evolutionary beast, the first, the second, the sixth, and the seventh.

Each level 6 crossbow arrow penetrated seven or eight level 4 evolution beasts in the midst of the burst of blood mist, each of which was like this, and then they were inserted into the last evolution beast with all their might, or plunged deep into the soil.

Among them, there were twenty sharp arrows that were not aimed at the fourth-level evolution beasts, but directly towards those sixth-level evolution beasts, but this time, because of the relatively high level, the sharp arrows did not penetrate their bodies, but were deeply inserted into their bodies.

Because the intuition of wild beasts is much more sensitive than that of humans, except for the more unlucky ones, who died directly after being shot at the vital point, the rest barely avoided the vital point at the critical moment, only adding a blood hole to the body.

With a terrible howl, the fourth-level evolution beasts that rushed to the front fell weakly, and were trampled by the group of evolution beasts behind.

Before the beast tide could riot, the next wave of four hundred sharp arrows shot out of the arrow tower again, and then another, and then another...

The attack speed of the arrow tower is very fast, basically one arrow can be shot every second, forming an uninterrupted network of firepower, constantly covering the entire beast tide.

In fact, this is not the fastest attack speed of the arrow tower, hundreds of crossbow arrows can be shot in more than ten seconds.

However, Yuan Sheng didn't do this, hundreds of crossbow arrows were shot out in more than ten seconds, if there were only about twenty, it was estimated that it would only be a few seconds, right?

And how far can the beast tide go in a few seconds? So let's not say that the accuracy will drop a little bit, just a waste of firepower, Yuan Sheng will never allow it.

Collapse Collapse

It was the sound of a crossbow bolt firing out like thunder.

Buzz buzz

It was the roar of crossbow bolts that pierced through the air, like a fighter jet flying out.

Puff puff

This is the sound of a crossbow arrow piercing through the flesh of a fourth-level evolution beast.

This voice was like an invitation from the king of Hades, like a reminder from a little ghost, completely covering up the terrible roar of the beast on the battlefield.

Tens of seconds, just a few tens of seconds, the three hundred and eighty arrow towers that used the fourth-level crystal nucleus as the power source stopped roaring, because there was no ammunition. Only the twenty arrow towers that used the sixth-level crystal nucleus as a power source were still firing furiously.

And the entire battlefield has now turned into a slaughterhouse, filled with the smell of blood, and the originally excited beast roar has been replaced by a terrible sound.

The entire beast tide had shortened by nearly half out of thin air, and the evolution beasts in the front row seemed to have not advanced a single step, and they were still thousands of kilometers away from Sky City.

Of the nearly 30,000 fourth-level evolution beasts and the more than 2,000 fifth-level evolution beasts, not even half of them could still move, and they were all injured, and few of them were intact.

Don't look at the crossbow arrows are relatively slender compared to the Evolution Beast, but they contain the violent energy of the crystal nucleus, as long as they penetrate the body.

You can tear the wound while opening a blood hole, so that the wound will not stop bleeding. One blood hole may be able to resist the evolution beast, two may be able to hold on, and three or four, even if it does not hurt the vital point, it will bleed to death.

Therefore, among these dead evolved beasts, there are not many who are completely hit by the vital point and die, most of them are bleeding to death in the process of running.

At this time, all the mid-level evolutionary beasts slowed down, and looked at the steel city not far away in horror, as if they were looking at a huge devil, and even some of the evolutionary beasts simply stopped, or turned their heads and ran in other directions.

It's horrible! It's horrible! I didn't see anything, I just felt a pain on my body, and I was injured, I can't stay here, where is there no food? Gotta come here!

Evolution beasts are not zombies, zombies can ignore their own injuries, as long as there is food in front of them, even gods can't stop them from eating.

But Evolved Beasts are different, they are flesh and blood, they are happy and angry, they are flesh and blood lifeforms, and they are also afraid of death.

In the face of death, nothing matters!

Disobeying the order of the seventh-level evolution beast, although the consequence is death, but that is a matter for the future, if you don't run now, you will die now.

In the face of dying now and dying later, many evolutionary beasts chose to die later, how long they could live, so many evolutionary beasts ran away.

However, these evolutionary beasts that ran were basically fourth- and fifth-level, and there were very few sixth-level ones, because the middle-level arrow tower really couldn't bring so much panic to the sixth-level evolutionary beasts.

Quack Quack !!

Roar!

Whew!!

Suddenly, there were several roars from the back of the entire beast tide, it was obvious that this was the voice of the five seventh-level evolution beasts, and the anger revealed in the voice could be felt by anyone.

Hearing these roars, those fleeing evolution beasts not only did not stop, but ran faster, for fear that those seventh-level evolution beasts would kill them and eat them.

At this time, these five seventh-level evolution beasts were very angry, very angry, especially the pitch-black crow, quacking and screaming.
