In the heart of Lancheng, even after the baptism of war, most of the skyscrapers still stand proudly.

Of course, the appearance has changed profoundly from when humans lived, and many of the Zerg directly dug holes in the wall as a passage mouth, and also spread a fungus blanket and hung sarcoma-like insect eggs, which looked like a bunch of black grapes from a distance.

This area is filled with a faint poisonous miasma, if ordinary humans are in this environment for a long time, it is very easy to cause organ failure and death, but for the zerg, this is the fresh smell of unobstructed breathing.

The Zerg who used to live here would generally nest in the nests of their own species, eating all kinds of ores and energy crystals that were plundered.

But during this time, there will be daily commotion here, and there will be friction and conflict between B-class zergs.

It was only yesterday that the main battle faction finally won a landslide victory, gaining dominance over most of the species.

They command the flying Zerg to scout in all directions, personally go out to integrate the low-level Zerg in the outer city, and send the Tunnel Worm to transport the stronger Zerg soldiers in the inner city, and launch a tentative counterattack against the approaching humans.

Not very effective, but they have given some of the human warriors a taste of death, and it is confirmed that these enemies are scattered after being attacked.

This is very advantageous for the Zerg, firstly, they can be defeated individually, and secondly, they do not need to gather tens of thousands of people on their side.

After all, there are more enemies outside Lan City, and once they detect the Zerg gathering together, they will definitely launch a devastating blow.

After so many years of fighting with humans, these high-level zergs have already accumulated a lot of war experience.

Time passed slowly until the appointed moment.

A loud scream tore through the night, resounding first through the area, followed by other piercing roars like an ominous sign.

Boom! Boom! Boom!

The unusually burly figure walked on the avenue, and every time the thick giant legs fell, it would shatter the ground and bring a strong shock.

The Saboteur, a heavy armor beetle that pushes the limits of genes.

Except for the huge head and horns, the rest of the place has changed drastically compared to the C-class.

The carapace that covered his entire body had completely fallen off, the new musculature had become unusually developed, and there was a layer of shiny translucent oil on the surface, and the limbs had swelled and enlarged into feet large enough to support him to walk upright, and four arms that could smash the mech's protective plates.

At the top of the towering building, the spotted insect, known as the killer of the air, spreads its broken bat wings and leaps out!

After a few breaths, several flying snakes in the adjacent area also appeared, forming a combat flight formation with the previous spotted insects.

Bang!

The entire wall was smashed through, revealing a bloated, round creature ten meters in diameter, which also traveled in a peculiar way, like a flesh-and-bullet chariot rolling forward.

There were many more B-class zergs coming out of the lair, and this time the total number of Zerg dispatched was 21.

Coupled with the mid- and low-level Zerg that were constantly pouring out of the buildings, it was clear that they were ready to start a more powerful battle.

This is not all their strength, because there are still nearly thirty percent of the elite forces that are not deployed, and they intend to stubbornly garrison here.

Under the leadership of this group of B-level zergs, the dense low-level zergs were divided into more than a dozen roads, each marching in different directions.

When the noise is gone, it is quiet again.

But that doesn't mean that the Zerg, who are considered stubborn, are ready to sit idly by, and they are also doing their job in an orderly manner.

The worker bee insect flapped two small meat wings, grabbed a large number of insect eggs and flew towards the magnificent grand theater.

The Titan predator who once ruled Lancheng is dead, and now it is a special B-class Zerg that occupies this place, enjoying the giant energy pillar on its stomach.

There are almost no insect signs to be seen from it, and it is more like the flying pterodactyl of the epic mythology of mankind.

The dragon head with two horns, sharp and sharp claws, nearly forty meters long, the whole body is covered with dark red scale armor, there are folded flesh wings on the back, and the long tail rests on the ground, which only occasionally sweeps.

Cizer, a Zerg with a large amount of dragon DNA mixed with genes, is the top existence among the B-class Zerg, and is called "Zerg Gladiator" by humans.

Although extremely scarce in number, it has been extremely conspicuous in every large-scale war.

After the death of the Titan Predator, Cizer became the most powerful Zerg in Lan City.

Under normal circumstances, the Zerg in the city should be under their command and start to break through to the outside, or fight to the death with the humans outside the city.

But all this did not happen, because it did not choose to take power, but chose another difficult path.

This Cizer has been lying here for a month, and during this time it has been trying to push the limits of its genes in order to advance to an A-class creature.

Such a move is not wishful thinking, but has a certain chance of success.

Several years of conquest have left its body scarred, but it has also loosened the genetic shackles in its body.

If all goes well, in another three or four years, it will be able to make the cut.

But the unexpected fall of the Titan Predator forced it to choose to move forward, knowing full well that this was the only way to break out of the current crisis.

The process of breaking through the genetic limit is long and painful, and the disorders that erupt in the body from time to time make its internal organs shatter by themselves, and the bones and flesh are constantly torn apart.

In such a weak state, it is inevitable that it will not be able to successfully break through the limit and achieve promotion, so it needs a lot of supplementation.

The energy pillar can help it recover from its injuries, but it is not enough, so it asks for support for its Zerg and sends a steady stream of nourishment.

These nutrients are the eggs that will hatch, and the trailing tails from the Sea of Death have shortened their lifespan and allowed them to emerge vigorously now.

However, in the current precarious situation, even if the eggs are broken, they are only fragile larvae and do not play any role in the situation, which is why the subordinates are willing to present their offspring.

Seeing that the eggs were piled up in small hills again, Cizer immediately leaned in and continued to eat, and soon consumed these nutrients.

The rich essence of life spreads through its body, nourishing and repairing its damaged body and alleviating a great deal of pain.

When it closed its eyes again and tried to break through, it felt that the barrier was a little weaker, and it seemed that it only took an extremely short time to tear it through.

Cizer, who made the breakthrough, had no defense, but it was not worried about its own safety, because the B-class zerg who had not left the inner city were basically hiding near the Grand Theater at this time, firmly defending themselves.

With a strong desire to break through, Cizer fell into a dark world, and the aura on his body gradually became weaker.

Far away in District 26, dozens of miles away, Alpha's night sweep plan has begun.

Qin Ming, who was walking on the road, suddenly felt a palpitation, so he paused his steps and reached out to hold the hilt of the black-bladed battle knife.

"Guide, what's the matter?" Yu Youzi, who was standing next to him, asked.

He shook his head lightly, but a look of solemnity flashed in his eyes.

He has not made any mistakes in his perception of danger until now.
