After all, the number of heavy machine guns was too small to fully cover the huge flock of birds, and a large gap appeared in the entire defense line. What was more fatal was that the flock of birds in the rear dispersed in a rush and surrounded the small town, and the firepower of several heavy machine guns decreased immediately. "Quack!!!" The next second, the group of pustular vultures arrived within a range of less than 100 meters in the blink of an eye. "Damn it! Where are the artillery? Hurry up and move it up." The commander in charge of the city defense looked anxious. He had no time to feel distressed now. Once these birds were allowed to get close, the consequences would be disastrous. "Captain Monet, the artillery is coming!" "Quick! Disperse the layout!" On the city wall, the captain who organized the artillery finally brought the weapons up. They should have opened fire when the machine guns were shooting. However, the mutant flock of birds came too suddenly and very quickly, so that the artillery team did not have time to deploy defenses.
These cannons are antiques that have been accumulated over many years, and some are weapons picked up sporadically in the wilderness. They are usually carefully maintained and are reluctant to be placed on the city wall in the sun and rain, so it takes a lot of time to prepare. They are in groups of two, carrying dark green barreled weapons on their backs. The style looks a bit like RPG rocket launchers, some are thick and some are thin, and you can see obvious different civilization styles. One person carries the barrel, and the other holds the barrel, forming an elevation angle and aiming at the birds and beasts. Some evolvers hold mortars and shoot directly at the nearby birds and beasts like holding guns. "Fire!!!" At the command, the artillery fire sounded. However, the first place to explode was the top of the city wall. For some unknown reason, a cannon exploded, and the surrounding soldiers suffered. These weapons picked up from the garbage dump and the antiques left over from the last century are very unreliable and almost on the verge of being scrapped, so the captain guarding the city is not surprised by this. The first round of shells arrived, booming among the birds and beasts, and the wings of the fragile birds and beasts were directly blown off and fell to the ground. Because the flock of birds and beasts was a large target, even though many guards were firing for the first time, the hit rate was very high and achieved good results. "Quick, quick, quick, reload!!" They could not be happy. During the interval of the artillery pause, the flock of birds that were attacking at high speed had already approached. Then, the guns of the guards defending the city wall opened fire. The types of guns in their hands were very chaotic, mainly PUBG series weapons, but also mixed with a lot of rusty antiques, and some guns with shapes different from those on Earth. Bullets of various calibers were released, forming a barrage, which made many pus vultures regretful. Small-caliber weapons were still a bit reluctant to these monsters, and even rifle bullets were not satisfactory. Although these birds and beasts could be shot, it often took a lot of guns to cause fatal damage. And because the soldiers needed to shoot at an elevation angle, the accuracy of the hit was not high. These mutant birds have strong vitality. The bullets made blood holes in their bodies, which aroused their ferocity.
"Quack!!!" A strange bird broke through the rain of bullets and pounced on the soldier. It was so huge that it stood 3 meters tall. It looked down at humans like a rabbit, with its wings slightly spread in a hunting posture, shrouding the soldiers in front of it in fear. "No! Get out of my way!" The soldier collapsed to the ground, raised an AK and fired wildly, making blood holes on the vulture's body, and it retreated again and again. The bullet hit the vulture's tumor, and drops of pus spurted out and sprinkled on him. "Ah!" The soldier made a miserable cry and rolled on the ground. The pus quickly burned through his leather armor like sulfuric acid, corroded large areas of skin, and even penetrated his bones and internal organs. He was not dead yet, but he was living a life worse than death. Then, in his gradually dimming eyes, a huge bird head occupied his vision, the scarlet eyeballs reflected the painful expression, and the next second, it pecked the head to pieces. After killing the soldier, the pustular vulture extended a tentacle-like tongue from its beak and inserted it into the chest of the corpse. The bird's tongue was stained red, the corpse was shriveled, and the soldier's blood was sucked away by the strange bird. In contrast, the wounds on the vulture's body healed a little. As the last drop of blood dripped, the pustular vulture excitedly licked its bloody beak, and it can be seen that the blood color in its eyes became much richer. Delicious! More! Food! Power! The vulture greedily glanced at the human soldiers who kept pouring onto the city wall, and then at the building full of delicious food behind the city wall, and rushed into the city with a quack. The battle on the city wall was fierce. As the grenade was filled, a new round of artillery sounded again, and the heavy machine gun was also rattling, the barrel was already red, and it was on the verge of being scrapped at any time. The strange birds also suffered heavy losses, with hundreds of them dead. These heavy weapons had a good killing effect on them. However, heavy weapons are limited after all. The larger number of birds and beasts in the rear have already flown closer, and a brutal melee broke out between people and birds. "Superpowers and evolvers, intercept them quickly!" At this time, Wei Qing, the head of the First Legion of Kra City, and several other leaders of Kra City also rushed to the city wall, leading the superpowers to strangle the approaching strange birds. Bullets and guns flew together, ice and fire and thunder roared. The voices of people begging for mercy and the screams of birds were mixed. "Quack!!"
A large bird with a wingspan of ten meters was extremely fast. It bypassed the fire chain of the heavy machine gun and crashed into the city wall under the rain of bullets. The appearance of this strange bird was somewhat different from that of an ordinary pustule vulture. The back of its head was in the shape of a cone, and a strange blue flame ignited at the end, which seemed to be hollow. The ten-meter wingspan of the strange bird gave people a strong sense of oppression. With a sweep of its wings, several soldiers around were blown away. This was not over yet. The flame behind its head suddenly burst, and its mouth opened. A ball of blue flame with amazing power sprayed out, turning a small section of the city wall into a sea of fire. "Ah! Help!" The temperature of the blue flame was extremely high. The evolved who was infected screamed and rolled on the ground. Instead, the fire became bigger and bigger, and it stopped moving after a few seconds. "Quick! Use the water ability to put out the fire for me." Several water ability users condensed water balls and poured them on the burned evolved. However, the flames went out, leaving only a wet charcoal on the ground. "What kind of fire is this? How can it be so powerful?" Maggie, the female leader, was very surprised. She was a powerful third-level fire-type mutant. She could also create such an attack, and even had a larger range. However, this strange bird looked like a second-level mutant creature. The terrifying thing was that there was more than one such strange bird. In other parts of the city wall, such blue flames had already ignited many times. "Leave this to me. All second-level mutants team up to kill the firebird!" "Yes!!!"
