When deciding to evolve again, Chang Haojie had already arrived underground. The room was filled with red jelly, all of which were evolution bases. To become a sixth-tier esper, one had to consume enough evolution bases first. The evolution bases in the room had already piled up into a small mountain.
Chang Haojie took a deep breath and then began to consume the evolution bases. Since he had already decided to become a sixth-tier esper, there was no need to hesitate.
"Today's battle proved that my esper ability's mist can disorient the mutated birds. As long as my ability's influence range is sufficient, I can shroud the entire city in mist. At that time, the mutated birds will be lost, and Yuzhou will be saved," Chang Haojie thought to himself.
After Yuzhou attracted the firepower of the southwestern region, many cities began to gloat. They mocked Yuzhou's current predicament, saying, "Heh, doesn't Yuzhou have the world's strongest espers? Doesn't it have two seventh-tier espers? Now is the time to see if Yuzhou can handle the attacks of so many mutated birds."
"That's right. When I looked online, there were quite a few people online from Yuzhou who kept mocking other places for not having enough power to protect ordinary people. Now it seems Yuzhou is nothing special."
The online discourse was also overwhelmingly one-sided. After Yuzhou attracted a large amount of firepower, the first reaction of other cities was not gratitude towards Shen Feng of Yuzhou, but rather mockery. The reason was simple: everyone was looking out for themselves. When they were suffering, you were deliberately posting videos to show off. Now that Yuzhou was under siege, they naturally gloated. As long as they were not in danger, everything was fine.
Shen Feng was very uncomfortable after seeing these online comments and put down his phone. The reason was simple: they were all human. Even if you couldn't help me, it would be best to offer encouragement. If not, then just stand aside and watch. But now they were laughing at me. Heh, I really don't understand these people's thought processes. Do they think it's a good choice to watch their compatriots suffer?
But reality was cruel. Shen Feng had to face the crazy attacks of the mutated birds. There was no other way. To achieve victory, they could only keep fighting until the mutated birds left voluntarily. If Yuzhou stopped resisting, the final outcome would undoubtedly be very tragic, because Yuzhou would fall.
When this morning arrived, Shen Feng stood in the square. The residents around the square had already been evacuated. Everyone had been notified that Shen Feng would use poison gas for attack at a critical moment, so everyone needed to seal their doors and windows. It was best to block even the gaps with wet towels so that the poison gas could not enter the house. Also, if anyone's doors and windows were damaged and could not be blocked, the best solution was to wear a mask and dampen it with water.
The people in the square were all wearing gas masks. If it came to a critical moment, they would need to open the high-pressure gas cylinders in the square, which were filled with highly toxic gas, enough to kill an adult. It was also fine for the mutated birds in the sky, but Shen Feng knew that if there were casualties, he would be cursed by many people. Even though he was so helpless now, as long as he accidentally injured others, this would happen.
The mutated birds reappeared and continued to attack Yuzhou. Every time the mutated birds flew over Yuzhou, the city had to counterattack. Espers unleashed their abilities towards the sky, while soldiers used machine guns to form a barrage, suppressing the mutated birds' attacks. As for Shen Feng, he would soar into the sky and personally engage in battle with the mutated birds.
Shen Feng wanted to gather a giant tornado hundreds of meters wide to sweep away all the mutated birds in the sky. It wasn't that he couldn't do it, but Shen Feng really couldn't. Because once he did, it wouldn't just be the mutated birds in the sky that would be damaged; countless houses on the ground would be destroyed. The inner city might be okay, but the families of the mercenaries living in the outer city would not be. Many of their houses were built with wooden boards. When the tornado appeared, it would first sweep away their houses.
Now, Shen Feng looked at the re-emerging mutated birds. The soldiers had already begun to fight, with bullets constantly sweeping towards the sky. Birds were also falling from the sky.
"Prepare to open these high-pressure gas cylinders. If we continue to stalemate, Yuzhou's economy will be completely ruined. I don't want to see Yuzhou's livelihood devastated a month from now. To avoid harming some people, and instead cause more people to live in hardship, that is something I cannot do." Shen Feng finally made a decision and instructed the soldiers in the square.
The soldiers quickly opened the high-pressure gas cylinders, which were filled with chlorine gas produced by Chu Chaoyan in time. Under normal circumstances, this gas was used to disinfect water and was often used in tap water. Because of this, tap water could not be drunk too much, as it could cause hair loss.
Yellow-green gas appeared in the air. When the valves on the gas cylinders were opened, the gas erupted like a fountain.
However, at this moment, Shen Feng suddenly saw a vast mist spreading from the distance. From afar, it looked like clouds falling to the ground, and the surrounding buildings were all shrouded in mist.
Chang Jianyi's voice came from Shen Feng's walkie-talkie: "Shen Feng, don't act yet. It seems Xiao Jie has successfully evolved. He can already expand the coverage of his ability. Yuzhou is now saved, and you don't have to do anything difficult."
When Shen Feng personally saw the mist spreading in all directions, he was also stunned. He didn't expect that the one who would eventually save Yuzhou would be Chang Haojie. He had thought that Chang Haojie's ability was hopeless yesterday, but now it seemed that when he had lost hope, his brother-in-law had given him a huge surprise.
"Quick, quick, close all the valves. I want to blow away the poison gas here. There's no need to take risks now!" Shen Feng said earnestly.
Upon hearing Shen Feng's words, everyone quickly got to work, closing the opened gas cylinders. The gunfire in the city gradually became sparse because the soldiers saw the changes around them. Countless mists flowed down from the mountaintops, quickly turning Yuzhou into a misty fairyland. The surrounding light became dim, and many people couldn't see their hands in front of their faces, soon finding themselves in the mist.
At this time, many old soldiers recalled the misty forest they had discovered when participating in the rescue of Rongcheng. The trees in the forest were also covered in mist. Now that this had happened again, had the mutated plants imprisoned in the laboratory been released?
Before everyone could figure it out, a notification came from the higher authorities: "The eldest young master has evolved into a sixth-tier esper to save Yuzhou. Yuzhou is now shrouded in mist because the eldest young master is using his ability."
At this time, people could no longer see the mutated birds overhead, so they stopped firing. The mutated birds in the sky saw the mist and quickly ascended, looking down. They also couldn't see the situation in the city and could only keep flying overhead, completely unable to find a solution.
A bird king led the mutated birds into the dense mist, seemingly wanting to blow away the mist below with its wings. However, after entering the mist, it completely lost its direction. Nothing could be seen in the mist, and even the birds' vision was useless. Without being able to see the surrounding environment, the birds' eyes were useless. They collided with each other while flying in the sky, causing casualties, and in the end, they could only reluctantly leave the mist and return to the sky.
"Finally, we are saved. The eldest young master is truly amazing. Thanks to the eldest young master, we now have a breathing space." After receiving the notification, everyone was very fortunate. Now that Yuzhou was shrouded in mist, it could be considered a good thing. The continuous battles of these days had been exhausting, and the soldiers were somewhat overwhelmed. Now, with the eldest young master's ability, the battle had come to a temporary halt.
However, this ability was not perfect. It was winter, and Yuzhou was experiencing a northwest wind. Therefore, under the blowing of the strong wind, the mist in the northwest began to dissipate. Fortunately, Shen Feng rushed to the northwest corner to take charge, using his ability to make the northwest wind bypass Yuzhou, thus preserving Yuzhou.
The mutated birds circled in the sky for half a day. According to the birds' experience, no matter how dense the mist was, it would dissipate by noon. This time was no exception, but in the end, things went against their expectations. The mist that shrouded Yuzhou never dissipated.
The most important thing for birds flying in the sky is their eyes. Birds have a special balance system. Some people say that there are gyroscopes in birds' heads, so no matter how the birds fly, their heads can maintain a certain horizontal position. This is actually achieved through vision. If they cannot see the surrounding environment, the birds' balance will be disrupted.
When they encountered the mist, the mutated birds did not dare to enter it. In the end, they slowly left at noon.
The departing mutated birds still wanted to retaliate against humans. Other cities within Yuzhou had long ago dug air-raid shelters and hid underground, taking all their food with them. The birds couldn't find people, so they returned to their previous cities, which was something other cities had not expected.
"What's going on with Yuzhou?" someone questioned online. "Why did the mutated birds come back? What did Yuzhou do?"
"Isn't Yuzhou very powerful? Then you should share the pressure with other sister cities. What do you mean now? Why did you drive all the mutated birds back?"
"I'm sorry, Yuzhou can't take it anymore either. We've killed millions of mutated birds, which is enough. You guys mocked us before, but now it seems you people are all talk and no action."
The discussions in Yuzhou online were also sharp. Yuzhou withstood the attacks of all the mutated birds in the southwestern region with one city for five full days, killing more than seven million mutated birds. This achievement was already very good, so the people of Yuzhou felt no shame. Instead, they began to mock the other cities for not having the ability to resist the mutated birds.
