There was also a dense sound of flapping wings in the sky, and countless mutant birds flew over everyone's heads!
It was already six o'clock in the morning after a night of fighting, and the sky was already slightly brighter, but at this moment the sky was already obscured by the spread feathers of the huge mutant bird. The light above the head was completely covered, not even a trace of light could shine through!
Thousands of birdsong and flapping wings passed over everyone's heads. The sound alone made people's scalp numb. The scene in front of them made everyone in the safe zone not even have the desire to shoot back. In this terrifying number
In front of them, the tens of thousands of people in the safety zone combined may not be enough to feed them!
"Quack!"
A dull scream that penetrated the sky erupted deep in the flock of birds. A pair of huge wings spread dozens of meters wide in the sky. Even thick clouds could not cover his huge wings!
Everyone looked at the sky in horror. The huge figure was hidden behind the thick clouds, but the thick clouds still could not hide his huge body. The huge body looked like a fighter jet. The moment it roared by, it stirred up excitement.
The sound wave makes people’s eardrums sting!
The energy detector alarmed frantically, and as everyone watched in stunned silence, the energy level rose rapidly. The energy radiation intensity of the nightmare crystal directly crossed the threshold of the fourth-order three-star, and was still rising slowly towards the fourth-order and four-star!
You must know that the mutant bird flies hundreds of meters high in the sky, and can detect such a powerful energy radiation level from such a distance. The true mutation level of this mutant bird will only be higher than the current detection and alarm!
Now everyone finally believed it, because even if Luo Xingchen really wanted to destroy the safe zone, he would never be able to attract so many mutants, let alone such a high-level mutant.
Luo Xingchen sneered: "If it was really the backup plan I left behind, I wouldn't even bother to lie to you. Now I also want to know what these things are about."
Everyone in the safe zone was silent as they watched the scene in the sky, raising their weapons and tremblingly towards the sky. But these birds didn't pay attention to the meaning of this safe zone and flew directly over the head of the safe zone.
Everyone looked at each other, but Luo Xingchen and Yu Tian suddenly narrowed their eyes at the same time, and a sinister look burst out from their eyes!
Because as researchers, they obviously felt some kind of panic among these mutant birds! These mutant birds were not looking for food, but running forward trying to stay away from something behind them, even ignoring everything along the way!
"There seems to be something behind them..."
"They...are avoiding something..."
The astute people in the various forces have also noticed this problem, and the tension in their hearts has become more and more intense! The fourth-order and four-star mutants and above are all running away, so how terrifying is the thing behind it!
"Don't worry so much now, kill the vanguard of these zombies first. They are about to attack the wall!"
"Prepare the machine gun tower, everyone is in position on the city wall, and pull out all the ammunition in stock. We have no time to waste!"
"Brothers, whether you can survive tonight depends on now!"
Gao Jian's voice woke up many combatants, but the expected unity did not appear. The eyes of the dozen or so forces were all panicked, and they all started to retreat on the spot!
"What are you doing and where do you want to go?!" Gao Jian was shocked and angry: "Leave now, don't you want the nightmare crystallization chromatography separation technology?"
A leader of the force had a horrified face and roared: "I want it, but I want my life even more. I don't want to be buried with you and this safe zone!"
"The safety zone in Luoxia City cannot be defended. If we want to survive now, we have to escape from the gate on the other side before the zombie wave breaks through! As long as we work together, we will definitely be able to break through a gap!"
At this moment, life and death were at stake and no one else could care about it. What the leader of this force said was exactly what the other forces were thinking, and they all nodded in unison.
"That's right, there is no need for us to be buried with you in the Luoxia City Safety Zone."
"I'm sorry. Although I want the technology very much, I want my life even more! And what we have on hand is enough for us to go back and do business!"
Some people persuaded Gao Jian to take Professor Liu and his family to escape with them, and even suggested not to tell other people in the city and use them as bait to delay their escape!
Gao Jianqi's face turned green. These guys had vowed to advance and retreat together with Luoxia City before. But now they wanted to run faster than a rabbit. At this moment, the complexity and selfishness of human beings were fully demonstrated.
What allies, what alliances, are nothing in the face of life, death and interests!
Luo Xingchen smiled coldly and said: "Haha, that's why I say you people are trash."
"Damn it, your back hurts when you stand and talk. You are a fourth-order evolver, and I am not! I think you are the one who lured the monster here, hoping to take the opportunity to seize control of the safe zone!"
A leader of the force roared, no longer caring about the fear of Luo Xingchen, pointing at his nose and starting to curse. At this moment, his subordinates had already prepared their vehicles. As long as the zombie wave and the army on the wall were fighting to attract attention, their best
The time has come to break out!
The same was true for the other people. They left one or two harsh words angrily and ran away. Only Zhang Daya and Liang Kun did not move. Instead, they stood directly beside Yu Tian: "We Yehehui are willing to cooperate with Luoxia."
The city's safety zone will advance and retreat together, so if you want to leave, just leave."
"Then you Yehehui just wait here to die!"
The Yehehui's choice surprised these forces, but there was no time to chat with Zhang Daya now. The convoy had already arrived, and more than a dozen forces rushed to the other side of the safe zone, apparently forming a temporary alliance.
Yu Tian looked at this group of people with an expression on his face, and was not surprised by this. Some people are admirable and live to die, while some people are born to be rats. But in the end of the world, rats often live longer than people.
longer.
The total of more than a dozen forces totaled a thousand people. Seeing such forces just trying to escape in a hurry, the originally low morale suffered another major blow. But there was no time for them to waste at this moment!
"The zombie wave has entered the attack range!"
The soldiers on guard immediately issued a warning, and Gao Jian pointed angrily into the distance on the city wall: "Fire!"
