After issuing the command to Sun Qiang, Lu Heng no longer followed it. Time would be the only standard to test whether the strategy of zombies eliminating zombies was feasible.
Being away from Sun Qiang would better test Sun Qiang's reliability. Lu Heng would not hesitate to eliminate Sun Qiang and its zombie army if any signs of uncontrollability emerged after some time.
Before leaving, Lu Heng equipped Sun Qiang with a tracking device, a product modified by the alien robot Evan.
The device was very small and was implanted in Sun Qiang's brain. Unless Sun Qiang ripped out its entire brain, it would be impossible to remove the tracking device.
Watching Sun Qiang and its zombie army gradually disappear, Lu Heng also left the area in his Direwolf.
Since he was out, Lu Heng had no intention of returning to Wuming City so soon.
Just as Lin Yu had said in those leader meetings, Lu Heng would not interfere with many of Wuming City's affairs.
He had handed over Wuming City entirely to Lin Yu and the others to manage.
Lu Heng needed to save more survivors who needed his help.
The Direwolf, under Lu Heng's control, flew at a very high speed.
Soon, Lu Heng found another city with human activity.
However, when he arrived, it looked somewhat desolate.
This was clearly a survivor refuge established after the apocalypse. The outer walls were not very high, and many places showed varying degrees of damage.
It seemed that this place had been attacked by zombies many times, but fortunately, the walls were still standing.
Lu Heng, riding the Direwolf, flew over the survivor city. The humans below could not see the humans above; they only saw a giant flying monster pass overhead.
Immediately, shouts and warning sirens sounded in the small city.
In times of zombie attacks, people could not afford to worry about attracting more zombies with their noise.
Even if they remained silent, the attacking zombies would still gather more and more.
Hearing the noisy and chaotic sounds from below, Lu Heng knew that, as usual, his arrival had brought panic to the people below.
Temporarily ignoring the panicked people in the city, Lu Heng surveyed the surroundings.
Since this place was frequently attacked by zombies, there must be a large number of zombies gathered nearby.
Lu Heng signaled the Direwolf to fly lower and discovered something unusual in the mountains near the town.
The vegetation here was clearly trampled, and due to repeated trampling, a wide path had appeared in the overgrown grass.
Lu Heng signaled the Direwolf to land on a gentle slope nearby. There were almost no zombies in this area, and the few he occasionally saw were not of high level.
After landing, Lu Heng put the non-combatant Direwolf into his spatial storage and released all his combat-capable contracted beasts.
Lu Heng issued commands to his contracted beasts with his mind, and they each took up their positions.
Those with flight abilities monitored the surrounding situation from high in the sky. As soon as zombies appeared nearby, they would inform each other through their minds.
Lu Heng, on the other hand, led the ground animals and proceeded along the trampled paths.
"Master, the scenery here is quite nice."
Fat Tiger, who had been released, looked around at the wild environment and occasionally ran back and forth in the grass.
"Be careful, don't run into the zombies' embrace."
"How could I? There shouldn't be any zombies here. Otherwise, the ground would not be so clean, and we wouldn't see any broken limbs."
Zombies' bodies were usually dilapidated. As they moved, they often dragged and dropped some limbs and parts.
Indeed, as Fat Tiger said, even in this deliberately trampled area, no broken limbs were seen.
"Still, be careful."
The Siberian Tiger reminded its unreliable mate. Some zombies, like these natural predators, had also learned to conceal themselves, waiting for creatures to approach so they could tear them apart and devour them.
Hearing his mate's words, Fat Tiger obediently ran back to the Siberian Tiger's side, taking on the role of a protector.
Lu Heng smiled and shook his head as he looked at the animals beside him.
If he hadn't contracted these animals, Lu Heng wouldn't have known that animals, like humans, had rich emotions and partners they wanted to protect and be with.
In human perception, many people would assume that all animals other than humans were inferior. They would not possess human-like emotional feelings, and when killing them, they never considered these aspects.
Following the uphill slope, Lu Heng and his group gradually reached the mountainside. The golden eagles in the sky also sent back information.
"Master, there's a large cave entrance on the mountain ahead."
"Does this path lead directly there?"
Lu Heng signaled the animals to stop and carefully inquired about the situation ahead.
"Yes, it leads all the way to that cave entrance along this trampled grassland."
"Are there any zombies nearby?"
"No, I don't see any zombies outside. Master, should I go in and check the situation?"
"No need."
Although the golden eagle had excellent eyesight and could see clearly in the dim light of the cave, Lu Heng felt that there might be unknown dangers inside. If there were zombies in the cave, there would definitely be a high-level zombie guiding the others.
Otherwise, they wouldn't have seen any trace of zombies along the way.
And this path would not have been trampled by humans or other animals.
Let alone humans exposing themselves repeatedly in the wild, judging by the condition of the trampled grass, it was unlikely that so many animals would be active in the wild for an extended period.
Lu Heng and the animals quickly approached the cave.
The cave entrance was very large, and it was estimated that the area inside was also considerable.
Logically, now that they had arrived here, with so many living creatures standing here, if there were zombies inside, they would surely be tempted to come out to them.
However, after standing for a long time, no zombies emerged, nor were there any sounds.
It was as if this was an abandoned cave, with no creatures for a long time.
But Lu Heng didn't believe it. Just the path leading down the mountain that had been trampled was enough to indicate that there should be something here.
Zombies had no body heat, so they couldn't be detected by infrared equipment.
Lu Heng took out a sonar device and placed it at the cave entrance. Soon, the device transmitted the situation inside.
Indeed, there were sounds inside, and these sounds seemed to be deliberately suppressed.
But how could they escape human technology?
Lu Heng detected many sounds emanating from within, not from one creature, or rather, not from a single zombie.
The sounds were mixed, all of them heavy panting.
However, based on the way the sound waves transmitted and the fact that human ears could not hear normally from the cave entrance, the zombies inside were deeply hidden.
