Chu Zhaoyan's poison gas attack was a formidable weapon, but she rarely used her special ability under normal circumstances. The reason was simple: if this ability was not used properly, it could harm those around her. It was only when Shen Feng was by her side that she could freely use her ability, and it was best done in an open space.
Once ordinary people inhaled the poisonous gas, their lungs would immediately fail. If the respiratory system collapsed, a person was essentially close to death. Even if they survived, their lungs would have multiple perforations, and their breathing would sound like a broken bellows, accompanied by blindness. Such a terrifying ability could not be used casually, especially in a city.
Chu Zhaoyan was persuaded by Shen Feng, and the two headed to the meteorologist's location. There, they found Chang Haojie also present, seemingly seeking advice. Several professors were patiently explaining something to him.
"Xiao Jie, what are you doing here?" Shen Feng, surprised to see Chang Haojie, couldn't help but ask.
Upon seeing his brother-in-law, Chang Haojie greeted him, "Brother-in-law, Second Sister, I'm asking a question. I want to know if my clouds can bring rain, and the professors are currently explaining the principles of rainfall to me."
Shen Feng quickly said, "Professors, please continue. We'll listen. Once Xiao Jie's matter is resolved, we'll ask our questions."
The professors nodded and then said to Chang Haojie, "We've just explained the principle of rainfall. The simplest form of rainfall is the convergence of cold and warm air currents, which will produce rain. Another point to note is the humidity in the air. Rain will only fall if the humidity is sufficient. If the humidity is insufficient, like in a desert, it's like wearing a fur coat in the morning and a thin garment in the afternoon, holding a stove while eating watermelon. Yuzhou is by the Yangtze River, so there's no shortage of water vapor. However, for rain to occur, we still need to wait for the cold wave to advance further south."
Chang Haojie understood half of the explanation, but the rest of the content was completely beyond his comprehension.
"So, can I actually achieve rainfall? I can clearly control clouds and fog, but I've never been able to create rain. Doesn't that seem inappropriate?" Chang Haojie couldn't help but ask.
The meteorologists were unable to answer this question. If it were a normal meteorological question, they were experts in climate issues, so how could they not answer? However, Chang Haojie's current question was related to ability users, and for a moment, they truly didn't know how to respond.
"This, perhaps it can rain, perhaps it cannot. In short, we are not sure. The only thing we can be certain of is that Young Master, your direction of ability development is incorrect. You have always used clouds to transport people or goods, but the coverage of clouds and fog is not large enough. Even if it can rain, it will only be a small portion," the meteorologist could not give a definite answer and could only offer a vague response.
"What? My direction of ability development is wrong? Should I be developing the coverage range of my ability?" Chang Haojie was stunned by the scientist's answer. He had been an ability user for four years, and in their eyes, his ability development direction was actually wrong. For a moment, he found it hard to believe their judgment.
However, the meteorologist nodded seriously at this moment and affirmed, "If Young Master wants to rely on his ability to bring rain, then that is indeed the case! Because only clouds with a sufficient range can potentially bring rain, but currently, Young Master's ability coverage is too small. Although it can carry people, the coverage range of the ability is too low. In my opinion, this is contrary to the purpose of rainfall."
"So that's how it is. I've actually got the direction of my ability development wrong. Heh, I'm leaving. I'll come back another time." Chang Haojie was deeply disheartened. He had been an ability user for four years, and his ability development direction was wrong. How could he bear it for a moment?
After Chang Haojie left, the meteorologists looked at Shen Feng and asked, "City Lord, do you have any questions you need us to answer? Please, feel free to ask."
Shen Feng also began his inquiry, "Professors, I want to know if we can use the climate to force the mutated birds to leave Yuzhou? Because if we resist the mutated birds normally, even if we manage to survive, Yuzhou will inevitably fall into chaos, which is something I don't want to see. I still hope that most of the people in Yuzhou can live and work in peace."
"I can answer this question. The answer is yes, climate definitely affects bird migration. Moreover, most of the birds attacking the city now are migratory birds. They are called migratory birds precisely because they migrate with changes in climate. Climate change will certainly force the birds to migrate," the meteorologist gave a positive answer at this moment.
Chu Zhaoyan quickly asked at this moment, "Then, with our current strength, can we change the climate conditions?"
The meteorologist did not answer directly but instead asked Shen Feng a question, "City Lord, I would like to know the coverage range of your current ability. Can you tell me?"
Shen Feng did not intend to hide anything on this matter and directly replied, "My ability coverage range is about ten kilometers. If I try harder, it can reach twenty kilometers."
After a moment of thought, the meteorologist replied, "Although this ability coverage range is vast, it is still too small compared to the climate system. I heard that the ship owner encountered a typhoon at sea. The typhoon at that time had a diameter of only thirty kilometers, and the entire typhoon had a coverage range of several hundred kilometers. Only when you reach that level of intensity can you change the entire climate."
Shen Feng felt hopeless upon hearing this and said, "This is impossible, because I am only a mere seventh-tier ability user. Perhaps if I reach ninth-tier, I might be able to do it."
The meteorologist thought for a while and said, "However, we don't need to be pessimistic. It is currently a mini ice age, and winter is arriving much faster than before. Perhaps it will snow in about twenty days."
Shen Feng nodded in agreement at this moment, but a solution to the mutated birds could not be found in the short term. They could only take it one step at a time. Human power was too insignificant in the face of nature. Even slightly altering the climate was impossible with humanity's current level.
After leaving the laboratory, Shen Feng said to Chu Zhaoyan, "You should still prepare to produce the poison gas. If we really can't hold on, I'll have to fly into the sky with the poison gas, but at that time, many people will likely die."
Chu Zhaoyan also nodded seriously. She knew that Shen Feng did not want to cause unnecessary casualties, but there was no other way. If they couldn't withstand the attack of the mutated birds at a critical moment, more people would die. At a crucial juncture, Shen Feng would have to choose to cut off the limb to save the body.
As Yuzhou attracted a significant amount of firepower from other regions, almost all the mutated birds in the entire southwest region had converged on Yuzhou. The Yuzhou region once again became a place of extreme tension. Many people had just thought the war was over and had no time to celebrate before the next crisis arrived.
Shen Feng never expected that the mutated birds would choose such a mad retaliatory action. While other areas had eased their pressure, Yuzhou's situation had become even more dire, which Shen Feng had not anticipated. If he had known this earlier, he would not have killed the mutated birds in Yuzhou for the time being.
In fact, besides using poison gas attacks, Shen Feng had other methods. One method was to find the bird king and kill it. However, times were different now. With tens of millions of mutated birds constantly circling overhead, it was impossible to find the bird king.
Within two days, the mutated birds had rushed to Yuzhou from all other areas. Such rapid transfer ability was something no other animal could achieve.
When the mutated birds arrived above Yuzhou, they immediately began their attack without delay, showing no hesitation. Yuzhou could only fight back desperately. Compared to the previous attacks by the mutated birds, this time the mutated birds' attack could only be described as frenzied.
"These damned feathered beasts, are they looking for death with such a frenzied attack?" Yang Chang couldn't help but curse when he saw the mutated birds' frenzied attack.
It was no wonder Yang Chang was so agitated. The mutated birds were pressing forward relentlessly, attacking the city in large numbers. Many machine gun barrels had turned red from firing too many bullets, and many machine guns had begun to malfunction. Although mutated birds were also falling from the sky, the number of birds falling was too few compared to the number of birds in the sky.
Due to the increase in mutated birds, the casualties among the soldiers had also sharply risen. Many people would be caught by the mutated birds if they were not careful. Even if they managed to escape in time, they would still be scratched. Some were even thrown from high altitudes.
Many people were looking forward to Shen Feng launching another brilliant counterattack. In their minds, City Lord Shen Feng was the most powerful person. As long as they could replicate the previous attack, no matter how many mutated birds were in the sky, they would ultimately be killed.
Unfortunately, the hypnotic pollen was gone, and it was impossible to successfully replicate the spectacular attack from before.
Upon seeing the mutated birds reappear, Shen Feng immediately used his ability and flew into the sky to counterattack. As soon as Shen Feng appeared, the surrounding mutated birds swarmed towards him. Mutated birds harbored deep hatred for humans, and now that humans had entered their territory, they naturally launched a frenzied attack.
Shen Feng calmly unleashed a move called "Eye of the Hurricane." A massive tornado appeared in the sky. The surrounding birds, affected by the strong airflow, lost control of their direction and were drawn into the tornado. At this moment, Shen Feng could protect himself, but the tornado could not cause substantial damage. As long as the birds left the tornado, they would regain their freedom.
"Furious Wind," Shen Feng continued without mercy, summoning countless wind blades in the sky to attack. The sharp wind blades were continuously launched in the air. Birds hit by the wind blades plummeted to the ground, with blood holes on their bodies, all pierced by the wind blades.
Li Keyi continued to stand at a high vantage point, using strong light to blind the mutated birds, but the effect was clearly not good. There were simply too many mutated birds, and the sunlight in the sky was also blocked. The amount of photons that could be obtained was reduced, and the power of the strong light was insufficient. The birds blocked the light from each other, making the blinding efficiency rather poor.
"If only there was a shield to block the entire city," Chu Zhaoyan sighed as she watched the fierce battle in the sky.
Chang Jianyi shook his head helplessly and said, "That's impossible. Even if we wanted to build one, the cost would be too great."
Chu Zhaoyan said to Chang Jianyi, "Ah Feng has already decided. If we really can't hold on or suffer too many losses, we will use poison gas for the attack."
Chang Jianyi said with difficulty, "It's a pity that Yuzhou's ability to produce gas masks is too poor. Otherwise, if everyone had a gas mask, we wouldn't have to worry about the poison gas attack."
The two were currently in the command center, watching the intense battle in the sky. They were helpless. At this point, any tactics were useless. The number of mutated birds was simply too great, while the human side had to continuously maintain the supply of resources, especially ammunition. Either the mutated birds would withdraw from Yuzhou, or Yuzhou's ammunition supply would not keep up, otherwise, the battle would not end.
At this moment, they saw a person on the screen. This person was flying in the sky, with white auspicious clouds beneath their feet.
"What does Chang Haojie want to do? Is he trying to fly into the sky at this moment?" Chang Jianyi was very nervous upon seeing this. Shen Feng flew into the sky because he had the ability to do so, but Chang Haojie flying into the sky might not guarantee his survival. Chang Haojie had clearly suffered before, why hadn't he learned his lesson?
