Just when Lin Xuan was in the midst of self-blame, a piercing air raid siren suddenly sounded from the Hope camp, Wu Yi looked up and found that a large number of flying ghosts were flying quickly in the sky in the distance, and the dense number formed a thick black curtain covering the sky and the sun, flying towards the direction of the Hope Camp like a dark cloud, and even the warm sunlight was completely blocked, which made people's hearts very depressed.

Seeing this terrifying wave of flying ghosts, the soldiers on the city wall were not stunned, they controlled the machine guns in the fortress, adjusted them to anti-aircraft gun mode, and formed a dense anti-aircraft fire to block the approach of the flying ghosts.

And the ordinary survivors and soldiers also raised the machine guns in their hands and swept the sky for a while, the flying ghosts that were dense in formation and did not fly at a high altitude were constantly shot by the machine guns, and the unlucky flying ghosts who were shot in the wings dropped sharply and became a more prominent target, and were shot in the air.

Approaching the walls, some of the Flying Spirits broke away from the group, swooped down from the sky, and launched a dive attack on the soldiers on the walls, leaving an afterimage in their field of vision, leaving countless bullets behind them, pounced on their targets, and then tore them repeatedly, and finally took their prey into the air and shared it with the other Flying Ghosts.

The speed of the flying ghost's dive attack was too fast, and ordinary soldiers couldn't react at all, except for a few unlucky ones who were hit by the dense firepower, almost all the rest of the flying ghosts were killed, and this wave of attacks alone reduced the battalion to nearly a hundred people, which can be described as a heavy loss.

Wu Yi and the other three also became the targets of several flying ghosts, but Wu Yi's reaction speed and shooting speed were not inferior to the flying ghosts that accelerated their flight, and when the other party swooped over, Wu Yi's-for-tat spur took the lead in stabbing the birdman's head, hurting it hard, staggering down from the city wall, and becoming a corpse when it fell to the ground.

The doctor was much more thrilling, the flying ghost left a claw mark on his protective suit, and you could see the clothes he was wearing inside, the doctor almost dodged this grab, the scalpel slashed at the base of the opponent's wings, and after the flying ghost flew into the sky again, the wings were under heavy pressure and the wound burst out, and a stream of blood sprayed out, and the flying ghost could not keep flying, and fell from the sky and fell into the sea of zombies.

Lin Xuan, with his powerful martial arts intuition, punched with all his strength when he couldn't make a move, and collided head-on with the claws of the flying ghost, Lin Xuan was knocked back by the powerful momentum, and the flying ghost was affected by the blood fist, his body stiffened for a while, unable to maintain the flexibility of coming and going like the wind, and was seized by the soldiers next to him to gather fire and die on the city wall in aggrieved.

When the battle on the city wall entered the white heat, the air defense network in the camp also showed its hideous face, and the land-based laser artillery formed a tight fire network, coupled with the support of anti-aircraft anti-aircraft guns, the whole sky became a sea of artillery fire.

Countless flying ghosts were shot down, falling from the sky to the ground with fire all over their bodies, the vitality struggled tenaciously on the ground, some unlucky survivors were caught by these injured beasts, and the camp had to organize a backup team to clean up the flying ghosts in the city.

Just as the camp was exerting all its firepower to block the onslaught of the flying ghosts, a majestic roar suddenly came from outside the city, this voice was sharp and piercing, full of the power of the king, and resounded throughout the battlefield.

All the flying ghosts seemed to be greatly encouraged, and became more fearless of death, and the speed suddenly increased, so that the shooting rhythm of many soldiers was disrupted, and more than a dozen people died at the hands of the flying ghosts.

Wu Yi felt a huge wind pressure approaching, and the soldiers looked up against the strong wind, and in front of them was a flying monster with wings spread and more than ten meters wide, and a huge shadow was projected on the city wall, making these brave soldiers who had experienced brutal battles stunned.

Notes: The Demon Pterodactyl is a super biochemical ghost with the ancient Pterodactyl gene, as the overlord of the air in the ancient era, the top of the entire food chain is stored zài, and the Demon Pterodactyl that inherits this gene is almost invincible in the sky. It dominates the flying ghosts, occupies the skies of the new era, and the ground beneath its feet is its hunting ground, and the prey it targets is generally difficult to escape the fate of death, and it is a terrifying creature that can engage in aerial combat with aircraft.

The Demon Pterodactyl has huge and broad thick fleshy wings, which can drive its multi-ton body to soar freely in the sky, flying far faster than ordinary flying ghosts, and the slightest vibration of its wings can set off a violent wind, flying sand and rocks to confuse the vision of humans. Its head was huge, with two sharp horns that curled and hideous, several meters long enough to string several adults together.

The Demon Pterodactyl also had long, sturdy skeletal limbs and sharp, green claws, and swooped down to dismantle a machine gun into scrap metal with a single swing as it swooped over the walls.

The body of the Demon Wing Dragon was covered with pitch-black fine scales, with a heavy texture, and the bullets of the machine cannon could not break through the defense of the scales when they were fired on it, leaving a white mark on it and then being bounced by the smooth scales. The effect of its wind roar had not yet dissipated, and the surrounding flying ghosts relied on this acceleration effect to frantically kill the soldiers on the city walls.
