The two zombies opposite were of the same level as it, and it would be somewhat difficult to deal with them if they attacked together.
It drilled into the nearest building and then slowed its movements, hiding within the structure.
Controlled by Lin Xue, the two zombies, only knowing to attack, rushed to chase after the zombie that had run out of sight.
However, due to the obstruction of the two-layered ice wall, they couldn't see where the dual-element zombie had gone.
They could only search blindly in the vicinity.
Under Lu Heng's instruction, Lin Xue had only issued the command for the two zombies to attack, but had not controlled their entire behavior.
This was because Lu Heng wanted to see the combat strength of these high-level zombies.
In his impression, high-level zombies often hid behind, controlling lower-level zombies to fight.
Scenes of high-level zombies fighting each other without control were indeed rare.
The two zombies anxiously searched the surroundings for the hidden zombie.
Just as their backs were turned, numerous ice spikes shot out from beneath their feet.
Several ice spikes instantly pierced the lower limbs of the two zombies, pinning them in place.
The zombies, lacking pain sensation, struggled to pull their lower limbs out.
However, the spikes were not short and had already penetrated their leg bones. With their stiff limbs, it was not easy for them to pull out.
After a few attempts, the zombie that had just shattered the ice wall swung a fist towards the ice cones.
Under the heavy impact of equal force, the ice cones instantly shattered.
The zombie saw hope and, without hesitation, swung its hand again towards the ice cones at its feet. Its body instantly regained freedom.
The other zombie was coincidentally also ice-elemental. The moment its feet were pierced, it had already controlled its ice abilities to free its impaled lower limbs.
The dual-element zombie's earlier release of its abilities had also exposed its location.
The two zombies, with bloody holes in their lower limbs, walked towards the house where the dual-element zombie was hiding.
As all the zombies had entered, Lu Heng couldn't see the situation inside the house, making it meaningless to watch.
Lu Heng, with Lin Xue, leaped down from the high wall and also entered the house with a leap.
He arranged Lin Xue in a corner of the house. As long as Lin Xue deliberately concealed its aura, the zombies lower than it would not be able to sense it.
Lu Heng only needed to approach the zombies alone, then hide in the space to observe.
Soon, Lu Heng hid in the space and saw the three zombies face-to-face.
The dual-element zombie growled again, likely still trying to persuade the other two zombies.
However, it had probably forgotten that there was a high-level zombie here that could control other zombies.
The two single-element zombies simultaneously launched attacks at the dual-element zombie.
A row of solid ice flew towards the dual-element zombie.
The other zombie struck the ground with both hands, and the floor in front of it instantly cracked, the fissures extending towards the position where the dual-element zombie stood.
The cracks beneath the dual-element zombie's feet grew larger. As it unleashed several ice cones, it also fell to the lower floor with the cracking ground beneath it.
"Truly useless."
Lu Heng shook his head, looking at the zombie that had just broken through the floor. He guessed that this zombie had not yet adapted to its abilities and intelligence.
Such behavior was no different from letting the opponent escape.
Seeing their target disappear, the two single-element zombies, although pierced by the ice cones thrown by the dual-element zombie, were not injured in the head and could still fight.
The two zombies walked towards the cracked opening, and with a leap, they also jumped down.
Lu Heng shook his head, emerged from the space, and teleported to the lower level through the opening, then re-entered the space to observe the battle.
In the end, the dual-element zombie defeated the two single-element zombies.
It created a diversion to separate the two zombies, then killed them one by one.
The dual-element zombie finally evolved to level thirteen.
The moment it evolved to level thirteen, Lu Heng appeared with Lin Xue, a slight smile on his lips.
"Congratulations on obtaining level thirteen, and congratulations on finally being able to end this sinful life."
As soon as Lu Heng finished speaking, under the zombie's terrified expression, its life as a zombie was ended.
Lu Heng walked outdoors, holding the newly acquired level thirteen crystal.
The silvery moon hung high in the sky, and a disgusting odor permeated the entire city.
However, this place had now truly become a dead city.
Lu Heng put Lin Xue into the space. They had been in continuous combat for several days.
Although Lin Xue was tireless, Lu Heng, who had to keep an eye on Lin Xue, was somewhat exhausted both physically and mentally.
Finding the rooftop of a nearby tall building, Lu Heng also returned to the space to prepare for rest.
...
Within Wuming City.
On Lin Yu's side, news of smooth progress was coming in from all over.
This also greatly boosted the morale of the survivors in the apocalypse.
Humanity's proactive attack on the zombies could be considered the official start of the human counterattack.
For a time, many ability users from large bases also became active.
Many unofficial ability user teams also joined the battle.
Although their objectives were not yet clear, most of them were motivated by the desire to profit and scavenge for supplies.
However, when they encountered zombies, they would also proactively attack, and for a time, human morale against zombies was even higher.
Lin Yu put down the report in his hand, a smile involuntarily appearing on his lips.
"The research center has also sent good news. They have developed a one hundred percent virus antibody and have already begun human trials."
"Yes, then speed it up. However, it's best not to use our own people for experiments. Find some villains from the apocalypse."
In the apocalypse, the evil side of human nature was amplified infinitely, and many people grew wicked claws.
They burned, killed, looted, and committed all sorts of evil deeds, becoming another sinful soul besides the zombies.
These people often possessed relatively strong combat abilities, and many small factions were often unable to resist them, only to be robbed and killed.
Of course, their abilities could not be compared to the personnel in Wuming City.
After all, soldiers from Wuming City operated in small teams of five hundred, and even villains of equivalent level could not contend with Wuming City in terms of numbers.
Therefore, Lin Yu planned to capture these people for experiments.
"Understood."
In fact, without Lin Yu's further instructions, the previous serum had already been experimented on using such people.
"Are there any new developments in other research?"
The research center of Wuming City was not only researching in one direction. In terms of technology and agriculture, they were conducting breakthrough experiments.
"Currently, only agriculture has made some progress. More crop seeds have adapted to the apocalyptic environment..."
Lin Yu looked out the window, listening to the report from the personnel below. The sunlight shone on his face, making his complexion appear very ruddy.
Everything was developing in a positive direction.
