Quickly came to the outside of the cave, and didn't need to ask anything, Huang Yi knew that something big was going to happen.

The distant earth rumbled, and endless roars came from the darkness, as if a rolling wave swept in, crushing and terrifying.

Huang Yi had never seen or heard of such a thing, and he instinctively trembled, not knowing what was going on.

"Everyone come out, this is the last fortress, if you don't rely on this place to resist, everyone will die", shouted a man in leather armor and holding a longbow on the wall of the Black Mountain Fort.

The Black Mountain Fort, the reason why it is called a fortress, is not just a cave to live in, the first group of people who came here at the beginning, when establishing the Black Mountain Fort, was obviously well thought out.

The cave is built on the mountain wall, and the periphery is a semi-circular wall, the wall has been thick and tall after ten years of building, and the stones of the wall are mined from the mountains on both sides of the Black Mountain Castle Cave, forming a steep cliff at least 20 meters high that extends out on both sides of the Black Mountain Castle Cave and extends out nearly a kilometer distance, which is to prevent mutant beasts from running from the hillside to the rear of the Black Mountain Castle and coming back to attack the people here.

The semi-circular wall of Fort Montenegro, the outer side is built very neatly, more than ten meters high, and after ten years of uninterrupted masonry, although there is no mechanical power all by manpower, but it is already very thick, the inside is a slope, which can make people go directly to the top of the wall, the bottom of the wall is at least more than 20 meters thick, and the top also has five or six meters, if you make a section. The walls are trapezoidal.

However, because it was completely manpowered. Without the pouring of reinforced concrete, this enclosure was not as strong as the walls of some cities. If you encounter a large mutant beast, you may be able to crush it entirely.

However, man is an intelligent creature, because the city wall is made of broken stones, in order to strengthen the wall, the stones are filled with branches and other things to increase the bearing capacity, three years ago dust clouds covered the sky, when the temperature was as low as more than ten degrees below zero, the people of Black Mountain Fort poured water on the wall to freeze, in fact, the city wall is already very strong, especially the frozen periphery of the wall. There are also many sharpened stumps, as hideous as hedgehogs, which are added to prevent monsters from colliding.

Because of this, Fort Montenegro is called a fortress, meaning fortress.

Hearing the roar of the man in leather armor on the wall, Huang Yichong woke up in fear, left and ran over and asked, "Who are you?" What's going on"?

When asking the other party, Huang Yi took the 'night vision device' and looked into the distance, and suddenly his body trembled subconsciously.

"Don't ask me who I am now. What about your weapons? Prepare to resist the onslaught of mutant beasts, the ant colony has rioted for unknown reasons, and many people have died as they swept through the area. In this direction, some mutant beasts did not dare to fight against the ant colony, and they were also fleeing for their lives. The early mutant beasts are not to be worried, mainly because the tens of thousands of ant colonies behind are the most terrifying"! The man said loudly.

While speaking. He had a bow and arrows in his hand, and the arrows were ready. It's going to shoot out at any time.

"Monster Wave"? Huang Yi exclaimed.

This situation, Huang Yi has never experienced it, in the past, Black Mountain Fort was safe and sound, no one has experienced this kind of thing, but the information in Huang Yi's mind tells him how terrible the monster wave is, even the smallest monster wave is a disaster, countless monster impacts, enough to destroy and tear everything that passes, unless a person's strength is strong enough to ignore the monster wave, otherwise no matter who encounters the monster wave, they can only dodge and flee, and fighting hard is the act of looking for death.

The man didn't have time to explain to Huang Yi, and he didn't care who Huang Yi was, maybe because Huang Yi was wearing the gorgeous robe left by Jiang Wei, the other party regarded him as the same outsider, and he didn't realize that Huang Yi grew up in Montenegro Fort, and he was also the 'boss' of Montenegrin Fort.

Swish~! At this time, the bow and arrow in the opponent's hand had already been launched, and an arrow tore through the air and shot out, and a python with a body length of more than ten meters that appeared on the ground hundreds of meters away was nailed to the ground by the arrow piercing its head.

This accuracy, this power, there is nothing to say.

However, he shot a python to death, but more mutant beasts appeared on the ground one after another, not only mutant beasts, but also people, and the mutant beasts were mixed with many outsiders who fled for their lives, and they had to fight with the mutant beasts on the side, which was extremely chaotic.

"Those people and mutant beasts were driven by the tide of ant colonies and fled here, this place, only Fort Black Mountain is suitable as a place to resist ant colonies, save them, save one more and have more power to resist the wave of monsters," the man said to Huang Yi, who was stunned on the side, while shooting arrows.

"Oh, what a ......", Huang Yi reacted with a spirit, and hurriedly raised his gun and began to shoot without hesitation, rescuing those who fled here among the mutant beasts.

A da-

Thundered~! The ground was trembling, and a thousand strange roars were constantly ringing, as if a storm was coming in this direction, which made people tremble.

Call~! A person has come to the wall of Black Mountain Fort, the other party is wearing camouflage uniform, and his body jumps on the wall more than ten meters high, he did not say anything, as if he had a tacit understanding, he climbed on the wall, and shot at the distance with a firearm nearly two meters long in his hand.

With a bang, a five-meter-long gray wolf appeared in the head of a gray wolf with a bowl size in the distance, and fell down in response.

"How can this be", Huang Yi's face was a little pale, how could there be a wave of monsters coming in this direction?

The wave of monsters was getting closer and closer, but more people came to the walls of Fort Montenegro, and without saying anything at all, they quickly turned around and began to resist the rushing monster horde.

The entire land outside the walls of Fort Montenegro suddenly became extremely chaotic.

Click~! After saving a few people in the monster group, the bullets in the several guns brought by Huang Yi have been finished, there are too many monsters and too far away, and it is impossible to kill them with one shot, often a monster needs a few shots to die, and the bullet consumption is very large.

There was no way, Huang Yi could only quickly turn around and leave the wall and leave, he didn't want to escape, but to get ammunition!

Quickly returning to the cave of the Black Mountain Fort, Huang Yi yelled while running to his room: "Everyone listen, go to the warehouse to get the weapon, hide in the cave after getting the weapon, the monster wave attacks, once a monster rushes in, kill them, whether you can survive depends on your own ......."

Huang Yi knew how much combat power the people of Montenegro Fort had, he didn't expect these people to save themselves at all, at most they were just making the last struggle, if the outer wall couldn't resist it, the people of Montenegro Fort would have no hope of survival.

Back in his room, Huang Yi grabbed the big package he had with ammunition and ran out, which contained all his ammunition and weapons, and the other package contained some food, and it was useless to take it.

When he ran out of the cave again, he said, "Block the entrance of the cave with stones, and let no one come out."

In the end, Huang Yi is still a person with a little conscience, knowing that the people of Montenegro Fort have no combat effectiveness, and coming out to help resist the monster wave is to send them to death, let them hide in the cave or many hopes of survival, he didn't think about distributing his strengthened weapons to them to resist the monster wave together, but that is unrealistic, not to mention whether the people of Montenegro Fort will use such a thing as firearms, the number alone will not be enough, it is better to use it alone to play the maximum effect.

When I returned to the wall again, there were already at least fifty people on the wall who were spontaneously resisting the wave of monsters, there were many monsters, some had rushed under the wall and were killed one after another, and many more were getting closer and closer, and there were still many outsiders fleeing for their lives.

"Ah~~!" , A scream came, Huang Yi just came to the wall, and saw a person being pierced by a huge boar with sharp fangs, and the boar's head swinged in the scream, and the other party was torn apart, and blood sprayed all over the ground.

Bang bang bang~! Woohoo~!

On the wall, the sound of gunfire and arrows rang out constantly, hunting mutant beasts one by one, and rescuing those who ran between the mutant beasts.

Other melee characters are already unsheathed and ready to slash monsters that come close.

Drink~! An angry roar rang out over the wall, and a strong man with a black sledgehammer rushed out, and the sledgehammer slammed down, and the air hummed.

Rumble~! He smashed his hammer on the head of a mutant cow with a body length of eight meters, and under the terrifying force, the cow's head shattered in an instant, and its body fell to the ground with a bang.

After killing the cow, the man didn't dare to stay too long in the face of the many mutant beasts, and quickly returned to the wall to wait.

At this moment, a large number of mutant beasts have appeared outside the wall, and all places are resisting, and the situation is extremely dangerous.

"People can't outrun the mutant beasts, if they continue to run for their lives, sooner or later they will be killed by the mutant beasts, and they can only make the last resistance here!"

Huang Yi understood in his heart why these people stayed here, there was no way, but he would not be desperate if he had the opportunity to escape, and after thinking about this, Huang Yi also joined the battle.

Putting the package beside him, he took out a few shots full of bullets, and shot at a spotted centipede in front of him that was about ten meters long, bang, bang, bullets, the centipede's head was smashed and threw to the ground, but it was trampled by a mutant cow five or six meters tall with a pop......
