On the other side, a zombie was holding a machete in one hand and a shield in the other, and rushed towards Xu Ye. There were already corpses lying on the ground around him.
As their intelligence grows, zombies will also know how to use weapons. It has to be said that this is another disaster for humans.
Phew! The energy on the bone knife shone brightly, and it stabbed straight at the zombie. The zombie hurriedly waved its shield to block.
With a pop, a large hole was pierced into this solid shield by the bone knife, and it was stabbed into the zombie's eye socket without stopping.
The most powerful characters in this battle have not yet appeared. No matter how much these cannon fodder are killed, it will be of little use, so Xu Ye is not in a hurry to jump into the zombie group.
Otherwise, his fire ability can kill these monsters on a large scale, but the elemental power consumed is very large, which is completely worth the loss.
As time passed, the defense of this forest was undoubtedly more difficult to break than the previous earth wall, until an hour later strange monsters appeared one after another, seemingly under the command of powerful monsters.
These were fiery red bees the size of a fist. They were densely packed, like a wave, and each one spit out fiery red liquid at the trees.
The fiery red liquid immediately burned as soon as it came into contact with the trees, and on the burning trees, there were also drops of fiery red liquid seeping out, spreading continuously towards the surroundings, as terrifying as an infectious disease.
The liquid spit out by the fiery red bee is a kind of venom, which can burn the blood and flesh in the living body to form new venom, which is extremely terrifying.
Just after spitting out the fiery red venom, these bees seemed to be sluggish and motionless.
With the emergence of various monsters with fire abilities, clouds of flames rose in the forest. The trees are mutant plants, but like ordinary mutant plants, they are also afraid of fire!
The flames soaring into the sky continued to spread, and the billowing smoke choked people to tears.
"Retreat! Return to the stronghold!" At the same time, Liu Rongfu's voice rang in everyone's ears.
A group of people started fighting and retreating, and quickly entered the stronghold.
Xu Ye stood on top of the tall city wall, looking at the forest that had turned into a sea of fire, with a burning fighting spirit rising in his eyes.
At this time, the sky was gradually dimming, and the woods outside the city turned into a sea of fire, burning blazingly. From the sea of fire, monsters gradually stepped on the scorched ground and walked slowly.
On the city wall, everyone's faces were surprisingly solemn. Many people who had fought outside the city still had traces of blood on their faces, but they were in no mood to wipe it off.
The sea of fire gradually extinguished, because monsters stepped on the sea of fire to extinguish it, and waves of fierce and bloody smells rushed in, and it seemed that even the city walls that were tens of meters high could not stop it.
Everyone was terrified. There were obstacles in the previous battles, so the beast tide could not come directly in front of them. They did not face many mutant beasts and zombies.
But now there is no barrier. Mutated beasts and zombies gather together. Standing on the tall city wall, it looks like a flowing black ocean. The eyes of all kinds of mutant beasts are flashing with fierce light, which makes people feel uncomfortable.
People's scalp feels numb when they see it.
"Don't worry, they can't break through the walls of our stronghold!" an older soldier said to a young soldier next to him.
The young soldier's body was shaking uncontrollably, and he suppressed the fear in his heart: "These monsters want to kill us, and I will definitely fight them until the last drop of blood."
Lu Jiao looked at the approaching beast tide from afar, without even a trace of amusement on her face. She whispered: "We must hold on. If these monsters break through the stronghold, maybe the next target will be our Rizhao stronghold."
Although the number of troops in the Rizhao stronghold is greater than here, their individual strength, weapons, and equipment are all too different. If they can't defend here, their Rizhao stronghold will definitely not be able to defend either.
The beast tide stopped for a while, and among the vanguard, a large monster with a powerful aura appeared.
Originally, the vanguard were just cannon fodder, but now the real battle is coming, and powerful mutant beasts are gradually appearing!
"There are so many large mutated beasts!" Everyone on the city wall also made their palms sweat when they saw monsters more than ten meters tall and twenty meters tall appearing in front of the beast group.
Each one of them has hard scales and a huge body. They are like a powerful mountain when they stand, giving everyone a heavy pressure.
"Roar!" The formation was re-adjusted, and a thundering roar sounded among the monsters. All the monsters seemed to have received orders and charged towards the stronghold city wall crazily.
The mutant beasts have surrounded the entire stronghold, and there are enemies on all sides at this moment!
"Boom, boom, boom!" Suddenly, a ten-meter-tall giant beast paused in its galloping steps, and a powerful explosive force came from the earth. A mushroom cloud seemed to rise from the spot, swallowing dozens of people around it.
Within a meter range, its body was torn apart by the bombing, and pieces of flesh and blood were splattered in all directions.
This is an explosive landmine buried in the ground. As long as the weight of stepping on it exceeds a certain limit, it will explode. Therefore, it is okay for humans to step on it, but it will detonate if a heavy mutant beast steps on it.
Boom! Mushroom clouds rose up for a while. Many monsters were too close to each other. Their ears were not blown off, but they were shocked by the huge explosion and were bleeding profusely.
The sound of explosions continued, and pieces of corpses were blown up to a height of 100 meters. Blood rained down on the rushing monsters, which made the smell of blood on the battlefield even stronger.
Mutated beasts with a physical constitution below level six will definitely die if they step on it. Those with a physical constitution above level six will be more or less injured. Only monsters with a physical constitution of level seven can survive the explosion of explosive landmines without any damage.
"Roar!" A twenty-meter-tall giant beast raised its two front hooves, standing upright, and then stepped heavily on the ground with a pair of front hooves that seemed to support the sky pillars, and a shock wave spread forward.
, stretching for hundreds of meters.
"Boom, boom, boom!" Suddenly there were bursts of explosions within the area, and dust and gravel flew into the sky, but no monster was harmed.
The giant beast continued to move forward, and from time to time it would stamp with its front hooves to create shock waves that would detonate mines on the ground.
There are only a few mutant beasts like Behemoth that can destroy mines buried in the ground with their own abilities. More mutant beasts use their flesh and blood to resist bombs.
Flesh and blood were flying everywhere on the battlefield, and the sound of roaring was endless. Even the timid monsters were stunned and did not dare to move forward.
But as soon as they stop, the mutant beasts behind them will rush in and push them forward. On this battlefield, no monster can retreat!
People couldn't help but feel chilled when they saw the monsters with blood-red eyes advancing against the scattered pieces of flesh and blood.
Monsters are monsters, and their nature is to kill first. Such casualties are not enough to make them retreat!
On the city wall, there were four black energy cannons. A man who looked like a sergeant looked at the surging beasts and said in a deep voice: "The monsters are approaching, please attack them with firepower!"
"Permission!" The voice from the walkie-talkie cheered everyone up. An excited smile appeared on the Master Chief's face and he shouted: "Let these damn monsters know that the majesty of human beings is inviolable. Fire at me!
"
Each giant cannon can stand on the top of the city like a hill. After the sergeant chief gave the order, the operators quickly started operating.
Energy crystals are constantly being put into the base of the giant cannon, and the mouth of the thick barrel is filled with the aura of destruction.
"Boom, boom, boom!" Ten seconds later, the cannon barrel roared with a thunderous roar. The entire city wall seemed to be shaking, and the awakened people around had already covered their ears.
With a loud noise that shook the sky, huge energy cannonballs rushed into the sky, attracting the attention of everyone or mutant beasts.
A huge cannonball with a diameter of tens of meters exploded in the sky, releasing huge shock waves that covered an area of nearly a kilometer in radius.
When the energy ball in the sky disappeared, a huge pit appeared within a kilometer radius. In this pit, there were miserable mutant beasts.
Some mutant beasts were directly crushed into powder by this shock wave, while some monsters with strong bodies carried them over. Fortunately, they survived, but their bodies were squeezed and twisted.
Only seventh-level mutant beasts had the ability to walk out of the scope of the shock wave, but they were still seriously injured.
"It's so terrifying!" Many soldiers were shocked when they saw this scene. There is no doubt that this round of blows gave everyone a shot in the arm.
Various types of energy cannons made loud noises, causing the casualties of countless monsters in the surging beast tide. Everyone looked at the crazy monsters.
"Damn it, aren't these guys afraid of death?" Liu Rongfu was a little angry when he saw this scene on the screen in the hall.
With several rounds of bombardment from the giant cannon, at least 20,000 to 30,000 monsters were killed in a short period of time, but these monsters still rushed towards the stronghold without fear of death.
"After all, there are ninth-level or even tenth-level mutant beasts among them. How can it be so easy to collapse their morale?" Su Bei sighed.
The best result is that these monsters fled in fear under the energy crystal cannon, but since the battle began, several ninth-level mutant beasts have died.
However, the mutant beasts at the peak of level nine and level ten have not yet appeared. Unless monsters of this level are killed in large numbers, it will be difficult for the beast tide to escape.
The battle was still going on. Under the attack of the terrifying energy crystal cannons, the mutant beasts suffered heavy casualties, but the consumption of these energy crystal cannons was also huge.
Not only does it require level seven energy crystals to drive, but each door cannot be attacked continuously in a short period of time, otherwise it will be unable to withstand it and be directly destroyed.
It is not an exaggeration to describe the scene outside the city as littered with corpses and rivers of blood. Even the awakened ones who have experienced many battles are extremely shocked. This is a cruel war!
As the giant cannons fell into a cooling state, the monster group that had been suppressed and unable to move forward regained its pace, and each one flew towards the stronghold.
"Fire!" Although the energy crystal cannon, a weapon of great destruction, could not be used, many soldiers on the city wall were attacking with machine guns, submachine guns and other hot weapons.
One monster after another fell to the ground under the covering fire, but more monsters continued to advance.
Finally, the monsters rushed under the city wall under the fire. Facing this tall city wall, they either used their own bodies or activated their abilities to launch ferocious attacks on the city wall.
