On the top of the city wall, countless anti-aircraft guns were densely arranged.
The weapons that shot down the flying monsters in the video before should have been these.
Their design was different from Earth's anti-aircraft guns; they were completely controlled by crystal cores.
The brackets and accessories were made of dark metal, but the barrels were white bones of varying lengths.
Because biological energy had a strong corrosive effect on metal, ordinary barrels could not withstand high-energy impacts.
Therefore, only the bones or certain organs of mutated creatures could be used as replacements.
This must be the power of technology that the progress faction called.
Zhang Chen flew forward a short distance, preparing to continue investigating the situation inside the city.
However, the gun platforms on the city wall, which appeared to be in a state of disrepair, began to rotate on their own.
The muzzles of seven or eight artillery pieces all aimed at Zhang Chen.
It seemed these artillery pieces were not very intelligent, unable to distinguish between humans and mutated creatures...
Zhang Chen shook his head helplessly.
But then he thought again.
At that time, the genetics faction was so suppressed by the progress faction that they couldn't lift their heads. Therefore, it was impossible for beings like the current survivors, who could use skills, fire energy beams, and even fly, to exist.
According to the logic of people at that time, anything that deviated from normal humans would naturally be considered a mutated creature.
Since they had already targeted him... why not try their firepower?
As Zhang Chen thought of this, he couldn't help but smile slightly and accelerated towards the anti-aircraft guns, diving down.
WHOOSH!
An energy beam shot out instantly.
Then two, three, four...
As Zhang Chen approached, the firepower of the anti-aircraft guns became increasingly dense.
Their attacks were not in the form of individual bullets.
Instead, they were continuous beams of light.
Moreover, the energy beams were relentless, with almost no gaps.
Soon, the firepower intertwined to form an impenetrable energy net.
At this level, not even a mosquito could fly in.
ZZZT!
The sky-covering energy net surged towards him.
An energy wave struck Zhang Chen's arm.
The energy armor activated its defense upon contact.
It left a scorched mark on the armor.
At the same time, the number of energy crystal cores in the bottom right corner began to drop significantly!
This was the consumption from high-speed flight and the energy barrier absorbing the damage.
As the apocalypse progressed, survivors gradually adapted to the new environment and continued to compete in killing monsters and leveling up.
Ordinary insects gradually lost their threat to survivors, and automatic alert sentry towers naturally withdrew from the stage of history.
Without this artifact for accumulating crystal cores while idling, Zhang Chen had to be more economical.
Once the energy crystal cores were depleted, they would be converted into energy crystal cores at a ratio of 1000:1 for continued consumption, which would be a net loss.
Zhang Chen had a general understanding of the attack patterns and power of the anti-aircraft firepower net on the city wall before slowly descending from mid-air.
Riding Er Pang, with Xiao Bai, he followed the crowd towards the crack in the western city wall.
Upon seeing the giant wolf, the survivors all dodged, afraid of being accidentally injured.
In the face of such a massive creature, even a Transformed one's heart would pound.
After all, the fear of colossal beings was ingrained in human genetics.
Soon, Zhang Chen reached the crack in the western city wall.
Seen from below, this crack was even more terrifying.
The solid city wall, dozens of meters thick, had been split in half, with a height of hundreds of meters!
What kind of terrifying power was this?
In his previous battle with the Spider Queen, Zhang Chen, with full firepower and using his only ultimate skill, Annihilation Finger, had only managed to cut through a dilapidated building.
The city wall before him, however, was dozens of meters long and hundreds of meters high, solid and wrapped in a special alloy metal mesh.
Its sturdiness was incomparable to one, or even dozens, of buildings.
It seems I need to continue to grow stronger; compared to the terrifying creatures of the future, I am nothing!
Zhang Chen silently resolved.
The number one ranking in the world looked like an honor, but Zhang Chen now realized it was a honey trap.
It made him feel invincible, causing him to lower his guard, become arrogant, and complacent.
The crack before him served as a warning: in the face of true terror, his strength was insignificant, and he must become stronger before the suppression was fully lifted!
No matter what his rank was, if he couldn't defeat monsters with their suppression fully lifted, the outcome would only be death!
The ground near the crack was piled with large rubble, with rusty alloy metal mesh exposed on them.
Even a small piece of rubble was as tall as a person.
The larger pieces of rubble were even bigger than Er Pang.
This... this is too strong...
A large number of survivors stood at the entrance, staring at the towering crack with awe and a hint of despair.
I just tried using Energy Strike, and it didn't even break through the outer layer of the city wall. I can't imagine how such damage was inflicted!
This... is this the strength of a monster after its suppression is completely lifted? I suddenly feel that leveling up is meaningless; my current efforts are just making me tastier... I have no ability to resist at all.
I'm numb. The natives could build such magnificent walls, yet they were ultimately wiped out. Can we really make it?
Forget it, I'll live one day at a time...
A group of people gathered at the entrance of the city wall crack, but no one was willing to go in first.
They were all terrified by the crack.
Although the monsters they encountered before were strong, they could still fight back with great effort.
Many who had advanced to the Transformed stage even felt that this apocalypse was nothing more than that...
However, seeing this battlefield, people finally realized their insignificance.
The path to survival was still very long...
Zhang Chen, riding Er Pang, jumped onto a large rock blocking the gap and peered inside.
Soon, a prompt appeared:
[This city changed hands several times in the struggle between natives and mutated creatures. There are some infected and mutated creatures on the streets, most of which will not pose any threat to you...]
[For those who appreciate technology, this is a treasure trove, with some war weapons and blueprints developed by the progress faction remaining...]
War weapons and blueprints?
Zhang Chen's eyes lit up!
The progress faction had even used these things to reverse-engineer mutated creatures and capture interface cities.
Therefore, these things must be very powerful!
With them, his strength would surely reach a new level!
Zhang Chen remembered that the first time he hard-countered a zombie horde, it was thanks to the armed mechs of the native technology.
History always repeats itself in surprising ways!
This time, I will become stronger!
With this thought, Zhang Chen, riding Er Pang, jumped directly from the giant rock into the city.
At the same time, the originally quiet city suddenly erupted with the roars of monsters, one after another!
