“Stop!”

Zhao Yu immediately gave the order for the entire team to stop.

The ten survivors immediately snapped to attention and not daring to move.

At this moment, Wolf stopped speculating about Zhao Yu’s background along with the others, raised his head to look at the overhead exhaust duct, listening intently to the movements of the alien.

“Dang dang dang!”

The sound inside the exhaust duct grew from distant to near.

Zhao Yu also slowly raised his hand, ready to signal his soldiers to open fire at any moment.

But just as the sound was about to reach directly above the farthest soldier, it abruptly stopped.

The shelter suddenly fell silent.

Everyone held their breath, staring nervously at the ceiling.

“Dang dang dang—!”

A noise started again from another direction, immediately shifting everyone’s attention.

“Another one?!”

Was the alien using a sound diversion strategy?

According to the movies, aliens possess hunting intelligence and often launch surprise attacks from unexpected angles.

In reality, they had recently encountered an alien.

They had thought the noise in the duct was an alien, but it turned out to be Skinny Monkey.

Considering how the alien moved through the exhaust ducts, it seemed unlikely that Skinny Monkey would have remained safe inside for so long.

If they thought of the worst scenario, Skinny Monkey’s safety might have been deliberately orchestrated by the alien.

They knew more people were alive below and wanted Skinny Monkey to divert their attention.

How do aliens differentiate their prey?

As depicted in the movies, there are many types of aliens. Some have eyes, and some don’t.

Some rely on heat sensing, others on hearing or radio wave.

But most aliens rely on pheromones to detect the unique secretions of other living beings.

Simply put, they use scent to locate their prey.

More advanced aliens can even discern the psychological state and emotions of their prey.

For example, whether the prey is fearful, afraid, or even excited, they can sense it and make corresponding judgments.

“Deng deng deng—!”

The noise from another alien approached from a distance and disappeared just as it was about to reach the soldiers’ heads.

An invisible pressure descended, and the ten survivors in the middle area broke out in a cold sweat, their faces filled with fear.

Even battle-hardened individuals like Wolf and his team were no exception, holding their guns tightly and staring at the ceiling.

If not for Zhao Yu’s prior instructions not to act during the battle, some might have already fired their weapons.

Zhao Yu understood that these aliens were indeed clever, far more formidable than other monsters.

However, he wasn’t panicked. His soldiers were robots, unfamiliar with the concept of fear.

This might also be why the aliens hadn’t attacked yet; they couldn’t figure out what those soldiers were.

“Dang dang dang—!”

A noise emerged from a third direction in the exhaust ducts.

The ten survivors in the area felt as if their breathing had stopped. Several of them turned pale, seemingly enduring some kind of torture.

“Relax!”

Zhao Yu knew they had reached their limit of fear and quickly spoke up to reassure them.

“If they were strong enough, they would have directly engaged in combat. It’s precisely because they know they can’t defeat us that they’re resorting to these tactical strategies…”

After hearing Zhao Yu’s explanation, everyone’s tense expressions slightly relaxed.

Monsters understanding tactical strategies?

Wat and his team didn’t understand, but they were shaken by the magnitude of it.

Yet, it seemed Zhao Yu was right; otherwise, why wouldn’t the monsters attack and instead kept making noises, affecting everyone’s emotions?

“Bang—!” “Bang-” “Bang!”

Gunshots rang out in the distance, startling everyone.

Zhao Yu turned to look, and the soldiers there had already automatically triggered the attack command, firing at an unknown creature.

“Stay here, I’ll go check it out!”

Zhao Yu quickly led a group towards the source of the noise.

The survivors glanced at the surrounding soldiers and only relaxed when they saw no movement.

Wolf hesitated for a moment before following Zhao Yu.

Red Pepper, worried about Wolf going alone and potentially causing a misunderstanding also followed.

After all, she was a woman and she could help alleviate some of Zhao Yu’s misunderstandings.

Soon, the group arrived at the scene.

In the room, seven or eight soldiers were circling and continuously firing towards the center.

“Sizzle sizzle sizzle—!”

Apart from the gunfire, there was also a strange sound.

This noise made Wolf and Red Pepper startled. Was this the sound of the monsters?

But then they discovered the truth.

The sizzling noise was not the sound of the monsters, but the sound of the monster’s blood corroding the ground as it dripped.

“Is it killed?!” Red Pepper asked nervously.

Zhao Yu moved closer and saw the motionless alien body on the ground, then nodded, “It’s dead!”

Wolf and Red Pepper exchanged a look, both feeling a sense of gratification as if a great enemy had been vanquished.

They hurried forward to inspect.

In the center, they saw a massive monster with its head blown to pieces, lying in a hole in the ground that had partially collapsed due to corrosion..
