Zombies are the product of the failure of human evolution, but since it is based on human evolution, the sense organs of course did not disappear, but evolved in a more suitable direction.

It's more suitable for hunting.

So with the exception of a few mutant zombies, most of the zombies' pain has disappeared, so that they don't have to stop fighting because of the pain.

But the rest is to become more developed.

When the light in the night lights up, the eyes of these zombies are inevitably hurt, and the light is too bright.

The brightness of these lights is more than three times that of the hottest summer in the old days. If the terrible brightness is directly found on the human retina, it will directly cause burns and even lead to blindness.

If it's long-term exposure, it almost certainly leads to blindness.

Fortunately, under Chu Feng's command, the human side turned their back to these light sources, and a few curious people who turned back did not suffer much.

After all, human beings will turn their heads after being hurt.

But these zombies have been ordered to die, and they still rush towards the direction of human regardless of everything. Even if their eyes are injured, they can still judge the position of their prey by their sense of smell and hearing.

"Suddenly, suddenly!"

The tongue of machine gun still kept jumping, and countless zombies fell under the machine gun fire, but some powerful zombies broke through the fire blockade by relying on their bodies, and then against the strong among human beings.

"When fighting, pay attention not to look back. You can judge the situation behind you by the shadow at your feet. These zombies have no brains and can't compare with human beings."

Chu Feng reminds a way.

Although it is true that zombies are generally stronger than humans, most of them are brainless.

So as long as we give human intelligence, zombies are not human opponents at all.

"When the eyes of these zombies are injured, although they can judge the position of their prey by their sense of smell and hearing, they do not have the help of their eyes, so it is difficult to cause precise and fatal injuries."

The chief of staff looked a little more relaxed.

The fighting environment should be bad for them, but now it's bad for zombies.

But his nerves relaxed for a moment, because when the zombies fell, the cavalry in black armor began to move.

Although the power of the machine gun is huge, even the heavy machine gun can't hurt the battle armor made of the nether world's cold iron, so these underworld knights can rush directly at the fire.

But they didn't do that. They chose to continue to enter the wall of the bundle.

Shuyuan's wall is a 40 kilometer long wall of fire. The opponent just destroyed a small part of it, and did not cause a devastating blow.

But now, these underworld Knights intend to continue to destroy the walls.

A psionic murmured to himself: "sure enough, it's still easy to deal with opponents without brains. What we fear most is opponents with strength and brains."

Although the zombies are terrible, they are certainly not the opponents of organized human beings.

With the command of these cavalry in black armour, the lethality of zombies suddenly increased.

"It's not easy to deal with."

Luo Xingyao rode on the horse back of the hell nightmare horse he just got and was ready to fight.

"Get ready to do it!"

Chu Feng jumped on the back of chasing electricity, and everyone was ready to fight.

"Since the wall of Shuyuan will be destroyed sooner or later, it's better to exert its value as much as possible."

The hellhounds broke away from the human side, and then spit out a dark blue flame in one mouth, with some black Hellfire in the middle.

Hell creatures can't feel samadhi's true fire, but it doesn't prevent them from developing hell's karma fire to samadhi's true fire.

When one of the three hellhounds spewed Hellfire, the other two spewed black wind, which greatly increased the speed and power of Hellfire.

The powerful Hellfire broke out in the zombie group behind the wall together with the Hellfire stored in the wall of Shuyuan.

Those zombies who were ordered to wait behind the wall were caught off guard and were directly erupted by hellfire.

Countless zombies howled, but they could not put out the fire.

Of course, the Hellfire in the wall of Shuyuan has also decreased a lot.

However, since these hellfires are destined to be solved, and the damage to the underworld knights is not too great, the best value is to deal with the zombies.

The blow just now has caused at least 3000 casualties of zombies. There are still 5000 or 6000 zombies whose flames can not be extinguished. Only a few powerful zombies can survive in the move just now.Suddenly suffered such a great loss, these cavalry who seemed to have no feelings also stopped.

After the underworld Knight stopped, these zombies, as if they had heard a silent command, began to withdraw from the rear in a large area.

"Are these zombies going to retreat?"

Many officers saw this scene with excited look in their eyes.

Since these zombies are under command, it's nothing to know how to retreat.

Although the opponents who know how to fear are more difficult to kill, for the relatively inferior human beings, they can retreat and reduce their casualties.

It gives them more opportunities to adapt and it will be easier to deal with in the future.

"Underworld knights are not afraid of death. They should not be retreating."

Chu Feng watched the movements of these underworld knights, and then his face became a little gloomy. "They should want to change an attack position, or let these zombies stay away from the wall of Shuyuan for a while, so that when they destroy the wall of Shuyuan, they can reduce a lot of casualties."

He didn't know much about the behavior pattern of the underworld knight.

After all, he had been fighting alone in his previous life. When he met such an organized opponent, he always ran away at the first time.

However, in the face of such opponents, no matter how careful can not be too.

If Chu Feng was allowed to direct the battle, he would do so.

The length of this defense line is up to 40 kilometers. If you want to change the direction of attack, it will definitely be a great pressure for human beings.

The chief of staff murmured to himself, "a greater disaster for mankind may come."

In addition to a small number of zombies still remain in place, most of the zombies, like the tide, disappeared in the vast darkness, and the knights in black armor also retreated.
