After Qi Lin sniped out the first "king-level" parasite, the second "king-level" parasite hidden in the black tide immediately took over the command from the dead king-level side and continued to control the hunting-level parasites that charged.

Qi Lin and the others had not yet been able to find the second king-level parasite, and those hunter-level had already rushed to the bottom of the city wall.

Although the flamethrowers mounted on the city walls can effectively kill and injure parasites approaching the city walls, the attack range of the flamethrower flamethrowers is only a cone with a base angle of no more than 45 degrees, and each cone has a distance of 20 meters, which will inevitably leave some dead spots that cannot be attacked.

And those who happened to burrow into the blind spot of the attack were able to survive.

These hunters clinged to the walls, their sharp claws easily piercing the surface of the walls, and they climbed towards the walls like geckos.

At this time, the role of the corner towers built on the cliffs on both sides of the city wall is reflected - these hunting-level parasites climbing the city wall and the ground show a near-vertical angle, at this angle, whether it is an anti-materiel sniper rifle or a large-caliber heavy machine gun, it is difficult to stretch out the city wall to shoot vertically below, and it is difficult for ordinary light weapons to threaten the hunting level. Constantly sweeping down the hunting-level parasites clinging to the walls.

However, due to the limitations of terrain and angles, there are only a total of three corner towers on the cliffs on both sides that can attack the hunting level that climbs the wall, and there are still many fish that have slipped through the net and climbed to the top of the city-

"Heavy shield troops, go up! Push those hunters off the walls! Fast! At the roar of the front-line commander, hundreds of tall soldiers rushed forward, all armed with heavy metal shields more than two meters high and more than one meter wide, and many sharp spikes on the front of the shields.

These shield soldiers were formed in groups of five, and the shields in their hands were constantly compressing the space for the activities of those hunter-level parasites who jumped to the top of the city.

Those who were close to the city wall were directly pushed and fell down by the big shield, while those who had already rushed out of the city wall for a distance were surrounded by two or three groups of shield soldiers, and finally the middle and high-level evolutionaries took action, or directly used large-caliber weapons to kill them.

After killing the hunters who rushed to the city walls, a team of soldiers who were responsible for handling the corpses of the parasites would immediately step forward and dispose of the entire corpses of the parasites with a special "disinfectant", and then throw them directly into the flames of the flamethrowers under the walls.

If these corpses are not disposed of in time, once the hatched parasitic worms take advantage of the war to parasitize the soldiers on the city wall, then the defense of the entire city wall will be broken down in an instant.

After paying more than three times as many casualties, the more than 100 hunters who climbed the city wall were finally dealt with by the players of the alliance, and at this time, most of the Kuroshio, which was moving relatively slowly, had just reached a distance of 300 meters.

The two rounds of artillery strikes had already been used by the players against the hunters who had climbed the city walls, and the bombardment effect could only be said to be barely strong, and the number of parasites eliminated was about 100,000.

The Kuroshio was so close that Qi Lin, who was so eye-catching, could even see a metal necklace around the neck of a parasite who was a young man in his lifetime, and the pendant of the necklace was a string of metal Russian letters "Белла", a female name, transliterated as "Bella", which means "beautiful".

"Step by step, there is no respite for us." Qi Lin glanced at the black tide that was surging towards the city wall under heavy firepower, and said with some concern.

"Well, the Kuroshio's offense is fast-paced, however, I guess the alliance should also reveal the first hole card - almost all the veterans of the Herrens Line are on the city wall, and the alliance can't watch them being consumed, otherwise they will definitely not be able to hold the city wall with those rookies."

As soon as Cheng Yanqiu's words fell, the sound of propellers rang out from behind the city wall, and Qi Lin looked back and saw that three Mi-28 "Havoc" helicopter gunships and twelve Mi-24 "Hind" helicopter gunships took off from a helipad hidden in the rear position, rose to a height of 100 meters, and flew towards this side.

This is the first time in the wasteland world that a unit flying more than 100 meters has entered the battle.

You know, in this devastated new world, the term "air force" can only survive in the dictionary of the old era for a long time.

Not to mention the radiation clouds full of electromagnetic interference, which will make various instruments of aircraft malfunction, make long-range guided weapons blind and other restrictions, the biggest reason why people dare not use airplanes, which was commonplace in the old era, is because the "air supremacy" in the wasteland is not in the hands of human beings at all.

All kinds of mutated birds and flying insects have taken over the skies of the wasteland, and in addition to this, there are terrifying beings such as the King Blood Dragon Lizard.

I don't know for what reason, the mutated creatures living in the air are far more territorial than the terrestrial creatures, and once a human aircraft passes through their airspace, it is often a never-ending chase and fight.

Due to technical limitations, the defense power of the aircraft has never been as powerful as the tanks and mecha on the ground, even a steel-winged swallow the size of a palm can easily destroy an advanced fighter that costs hundreds of millions.

Strictly speaking, these dozen or so helicopter gunships dispatched by the alliance cannot be regarded as an "air force" but can only be regarded as an "army aviation unit," and in the code of operation for the pilots of these helicopters, the first item listed is that "it is forbidden to rise to an altitude of more than 150 meters, and it is forbidden to fly away from an area with a radius of five kilometers centered on the apron of the base." ”

The dozen or so helicopter gunships first fired several rounds at the Kuroshio's front line with aviation cannons and honeycomb rocket launchers from a distance of several kilometers, and then flew directly over the densest area of the Kuroshio and dropped one after another ovoid bombs from the cabin.

Qi Lin recognized at a glance that special oval bomb, that thing was called "napalm aerial bomb", which once shined in the Dongying bombing of World War II, a bomb weighed 500 kilograms, and was filled with gelatinous napalm and white phosphorus, and its lethality and killing range were not comparable to those incendiary bombs that were several sizes smaller than those fired from artillery.
