The older ones among these staff officers still remember the strange beasts from more than ten or even twenty years ago.
Although the strange beasts at that time were extremely ferocious, humans were able to defeat them every time with the help of the city walls.
But those guys are indeed evolving. Although their body shapes, appearances and even species prototypes are all very different, they seem to have a convergent evolutionary direction.
At the beginning of the year, the research institute and the General Staff jointly confirmed the new tactics of the alien beasts. However, in less than a year, is this record going to be broken again?
Before today, human beings' understanding of alien beasts' intelligence was still stuck at the tactic of second-level alien beasts using first-level alien beasts as meat shields.
Although this also represents a kind of evolution, there is a forced factor involved. The second-level alien beasts will naturally suppress the first-level alien beasts, and it is not impossible to force the other party to become a meat shield.
But now, it turned out that the second-level insects, because of their body structure, were willing to transform into steps one after another, allowing the first-level beasts who could roam freely in the wilderness and plains to step on their bodies and climb up the city walls.
This is impeccable evolution.
And being able to make thousands or even hundreds of millions of insect-like beasts die together, perhaps they hope that there really is a supreme will outside the city that controls these lower lives.
Having said that, the most important thing at the moment is not research, but how to deal with this tactic.
At this time, outside the walls of Hope City, the corpses of insects were densely packed into more than ten layers, and the fishy smell of their body fluids had even been blown to the top of the walls.
The soldiers who had the right to open fire freely had already used many common methods to block the attack, but the problem was that at this point, even if many monsters died, no one would move their bodies away, and the so-called stairs would only become wider and bigger.
However, if a large amount of explosives is used, it will inevitably affect other humans fighting on the front line, and even cause greater damage to the city walls.
At this moment, the radios near the west gate of the outer city area sounded, and a voice that was very familiar to everyone began to announce new orders.
The soldiers who were firing were actually ordered to retreat to the inner edge of the city wall.
No one suspected that the order was fake. Radio was one of their few forms of entertainment, and it took less than half a second to distinguish a few familiar voices.
And the voice on the radio now belonged to the man who usually broadcast serious news, so the soldiers had no doubt about it.
Although they didn't know why they did this, they understood from listening to the emotionless countdown on the radio that some plan was being formulated or implemented.
In such a plan, being accidentally injured or killed by friendly forces is not a good thing. After all, this is not a game where you can turn friendly damage on and off freely.
They quickly retreated, giving up three quarters of the front area of the city wall, and all gathered behind the last line of cover, waiting for what was about to happen.
The same countdown continued to echo in the command center. Everyone was silently looking at the big screen in front of them, waiting for the super-powered person to take action.
Yes, just now, the command of the area around the West Gate, where the fighting was the most brutal, was briefly transferred by the Spire to a super-powered person from the first team - Xingluo.
If you raise your view to a higher angle at this time, you can see an energy barrel at the top of the spire that constantly adjusts its output power handle to store energy.
At this time, "Xingluan" was constantly making fine adjustments with the help of the position coordinates provided by Wanjuan.
As the thirty-second countdown reached zero, a burst of noise flashed across the large screen in the command room, and then the no-signal sign flickered slightly.
Apparently, the camera had been destroyed by the impact of an explosion or something.
Such a shock wave obviously could not be felt by the people in the inner city command center. Deprived of their vision, they could only use communicators to communicate.
"Hello, report the situation at the West Gate."
"Got it."
An unclear voice came from the other end of the communicator:
"The stairs near the city gate have been basically destroyed, and the living monsters are filling it up."
"Keep observing!"
"yes!"
On the terrace of the central spire, Starfall’s brain was working rapidly.
The power of the energy cannon is too strong. The operation just now was like driving heavy machinery to open a small glass bottle, and it could not cause any damage to the bottle. Even if it could be controlled by mind, the precision was far beyond the reach of ordinary superpowers.
With the data just now, "Starfall" is constantly correcting its trajectory, striving to increase the power of the next shot while reducing damage to the city wall.
But... as she looked at the images sent back from the direction of the outer city wall, she couldn't help but feel a little helpless.
The feeling of having super-standard weapons but not being able to fire at will is really frustrating.
Outside the city wall, there were endless strange beasts all over the mountains and plains, and it seemed that they could not be killed at all. Even with such heavy firepower, it was of no use.
In the scene that "Xingluo" saw, the big pit that he had bombed just over ten seconds ago was now filled with strange beasts again.
Those fearless guys began to build stairs with their bodies again, and the top of the stairs close to the city wall was less than five meters away from the wall.
The west city gate was where the most strange beasts gathered, so she had to immediately fire a second time to ensure the temporary safety of most people.
However, at this moment, something strange happened——
"What's going on? The picture..."
"Xingluo" stared at the screen in front of him with wide eyes, not understanding why multiple cameras so far away from the West City Gate suddenly lost their signals.
The cameras near the explosion site were naturally destroyed by the aftermath. She had been calling up surveillance cameras farther away for observation and correction, but in less than a second, dozens of cameras suddenly stopped responding.
"I didn't open fire..."
Xingluo was somewhat puzzled, while "Wanjuan" who was standing not far away immediately began to repair the communication.
---
Outer city area, west gate.
Just now, there was a violent sonic boom, followed by violent shaking of the ground and countless tiny particles of dust.
It was as if a missile exploded near the city wall, and everyone suffered a brief tinnitus.
"Is this our cannon?!"
"I can't hear you clearly!"
"I say!"
"I can't hear you clearly!"
Such chaotic conversations were heard everywhere on the city wall. After confirming that they could not communicate with each other for a short period of time, the well-trained soldiers and super-powered people quickly prepared for battle and looked at the smoke that was still spreading in the distance.
