"I understand, I understand why it's like this. This is the mutated birds taking revenge at this very moment, it must be so, I won't guess wrong, it's definitely the situation I described, the mutated birds have gained preliminary intelligence, they have the concept of revenge, and last year, North America poisoned and killed more than half of the mutated birds. After the mutated birds sensed this, they began their retaliatory actions," an animal behaviorist shouted in the research institute within Yanjing City.
To understand why the mutated birds were attacking the city, one had to know their behavioral logic. This was generally studied by animal behaviorists. By studying animal behavior, one could understand the logic behind their actions. At this moment, the animal behaviorist had already deduced the logic behind the mutated birds' attack on the city.
Yanjing was currently in a state of panic. People had heard the news that all the cities outside the pass had fallen. No one could have imagined such a thing. In just one day, all the major cities outside the pass had been breached by mutated birds and mutated beasts. This kind of thing wouldn't even fool a child if it were a fairy tale, but it was happening before everyone's eyes, and they had no choice but to believe it.
However, at this moment, an assistant asked, "Teacher, but it wasn't us who released the viruses. It was the North Americans who released the bacteria and viruses. Even if the mutated birds want revenge, they shouldn't be looking for us, should they?"
The animal behaviorist looked at his student and then said helplessly, "What are you talking about? Do you think there's a big difference between a red-haired gorilla and a silverback gorilla when viewed through human eyes? In the eyes of birds, they only need to know that humans caused their population to decline. If there are humans in North America, doesn't that mean there are humans in Asia too?"
At this moment, Yanjing was already in great danger because the mutated birds had arrived outside the city. Although they had not attacked yet, the number of mutated birds in the surrounding areas was too large, and Yanjing was in danger at any moment.
"Teacher, what should we do next? Should we hide in the air-raid shelter?" the student began to ask.
The animal behaviorist shook his head helplessly and said, "You can hide for a while, but not forever! The mutated birds now consider humans their ultimate enemy. To survive, there is only one way: either eliminate all the mutated birds, or be relentlessly retaliated against by the birds."
There is indeed revenge behavior among animals. Whether it's bears or elephants, they can remember human faces and seek revenge. Among birds, crows are quite intelligent. Even after more than ten years, crows will not forget to take revenge. Therefore, for humans, they are now being targeted by mutated birds. To survive, there is only one way, and that is to completely eliminate the mutated birds, otherwise, the war will not end.
"Is there no better way? For example, to eliminate the hatred between both sides and coexist harmoniously?" the student continued to ask, as eliminating mutated birds was too difficult and could not be achieved overnight.
Unfortunately, such fantasies were ruthlessly shattered by the professor. "Coexist harmoniously? What are you thinking? When have humans ever coexisted harmoniously with animals? The so-called harmonious coexistence is when humans occupy the majority of resources, and animals get a small portion that humans don't need. At this moment, the mutated birds have become powerful, and they are bound to obtain more resources, such as food and habitats. Humans cannot tolerate this either, so in the end, the outcome is already determined. Humans, mutated birds, and mutated beasts are now in a situation of irreconcilable conflict."
After the professor explained the fundamental conflict between humans and mutated birds, the student finally understood why the mutated birds had to attack humans. Besides revenge, it was also to fight for resources. The existence of humans occupied a large amount of resources, which the mutated birds would definitely not accept.
At this moment, the air raid sirens sounded over the city. The people in Yanjing hurried to find nearby air-raid shelters to take cover, while the soldiers were already in position. Combat personnel stood on the streets and rooftops, preparing to meet the attack of the mutated birds.
At this time, fighter jets were also taking off from Yanjing Airport. Three thousand fighter jets took off one after another, equipped with sufficient weapons, including missiles and machine gun bullets.
Wu Zhenyuan sat in the cockpit and said to the team members behind him, "Remember to follow me when we fly, and don't get surrounded by the mutated birds. Our battlefield is outside the city. Also, conserve ammunition, don't use all your bullets at once, and don't fly too fast. Remember to save fuel, as we need to return."
Wu Zhenyuan was no longer the naive soldier he once was. He had now become a captain with several team members under him. He suddenly understood how his sacrificed captain viewed him. On the battlefield, he was also responsible for bringing these children back, which was a heavy responsibility.
The young team members had all heard that their captain had participated in the Yanjing defense battle a few years ago. At that time, they were just hiding in the city. Now, the team members began to ask, "Captain, I heard you participated in the Yanjing defense battle before, is that true?"
Wu Zhenyuan calmly replied, "That's right, that happened. It's precisely because of this that I always ask you to be prepared before every mission, especially with ammunition, otherwise, it's very easy to sacrifice."
Wu Zhenyuan still could not forget how his captain died! No one expected that at that time, the Corpse King had already allied with the mutated birds. The fighter jets were originally carrying out bombing missions against zombies, but later, to prevent the mutated birds from approaching, the captain and the other veteran pilots charged forward, sacrificing their lives to buy time for Yanjing's defense.
"Captain, with so many mutated birds, how can we fight them?" suddenly a team member asked, interrupting Wu Zhenyuan's thoughts.
Wu Zhenyuan then replied, "Just follow me closely. Fight in the formation we trained. Remember, when engaging in aerial combat, you must fly very high. If your flying altitude is insufficient, you will be surrounded. Mutated birds are very good at fighting with their lives for lives, so you must avoid dogfights and use your maneuverability to gain victory."
After speaking, it was their turn to take off. Wu Zhenyuan said, "Maintain communication, microphones on at all times, prepare for takeoff."
Wu Zhenyuan made up his mind. He was determined to bring the team members behind him back safely.
The attack of the mutated birds had begun. Yanjing still had a population of over six million people and was a major city. The mutated birds were clearly aware of this, so they waited until tens of millions of birds had gathered outside the city before launching their attack.
Facing the charging mutated birds, the first line of air defense was surface-to-air missiles, which were fired specifically at areas where the mutated birds were densely packed. One launch could kill hundreds of mutated birds.
The second layer of defense was anti-aircraft guns. Some anti-aircraft guns were automatically aimed, while others were manually operated. It was difficult to say which was better, because automatic ones were difficult to use once they malfunctioned, while manually operated anti-aircraft guns were not accurate enough. However, facing the endless swarm of mutated birds, as long as a barrage of bullets was fired, it would rain blood from the sky, and aiming at that point was not very important; what mattered was sufficient firepower.
The third line of defense was heavy machine guns, along with the defensive strength of ground soldiers. Although their power was not as great as the first two, they had the advantage of numbers.
Once the battle began, the mutated birds grabbed small mutated beasts and set off. Upon reaching the sky above the city, they would directly drop the captured mutated beasts from the air to cause chaos in the city, while the mutated birds would constantly harass from the air.
Ability users also stood on the rooftops to deal with the mutated birds. Li Keyi was the most eye-catching presence at this moment. Dressed in white, she stood at the top of the tall tower, becoming the focus. The sunlight in the sky seemed to converge on her, making her look so sacred. Coupled with her title as the Goddess of Light, she was now considered a true goddess in the hearts of many.
Li Keyi did not expect Yanjing to encounter such a crisis. If it was not handled properly, Yanjing City would be breached.
At this moment, Li Keyi was applying her control over light. Intense light erupted from her body, continuously blinding the mutated birds in the air. Birds have very powerful eyesight, but precisely because their eyesight is so keen, they are easily blinded by strong light. Li Keyi continuously shone light into the birds' eyes, causing them to be blinded.
Once blinded, the mutated birds lost their sight and eventually fell to the ground. Once they fell to the ground and lost their advantage of flight, the birds could only be slaughtered.
Some elite mutated birds discovered how troublesome Li Keyi was and directly launched a sneak attack. However, Li Keyi had a very high level of mastery over light, with no blind spots in her 360-degree vision. For the mutated birds that attacked her by surprise, Li Keyi directly summoned a two-meter laser sword, which could split them in half.
In the distance, Jin Zijue and Xiao Sheng were together. Seeing Li Keyi's stunning performance, they were also surprised. Jin Zijue even said directly, "Li Keyi has definitely become a seventh-tier ability user, otherwise, with the way she's using her abilities now, her stamina would have been exhausted long ago. It seems the title of Yanjing's strongest ability user can only be given to Li Keyi."
Upon seeing Li Keyi's performance, Jin Zijue and Xiao Sheng both realized that Li Keyi had definitely broken through the evolutionary barrier, otherwise, she wouldn't have performed so astonishingly. As for why Li Keyi had evolutionary crystals, they knew it well. Earlier, at sea, Li Keyi and Shen Feng had taken advantage of the chaos and stolen several evolutionary crystals.
Before this, there were still many disputes regarding the ownership of Yanjing's strongest ability user. Some people thought it was Xiao Sheng, and some thought it was Jin Zijue. But after seeing Li Keyi's performance today, everyone knew that at this moment, Yanjing's strongest person was definitely Li Keyi.
