The intense gunfire reverberated in the air, a searing pain echoing in everyone's ear drums.

"Ahhhhh!"

"They're coming from behind! There's so many of them!"

While everyone's attention was drawn to the creature lurking in the sewage, screams erupted from the rear.

In the dark depths behind them, numerous red figures flickered. These creatures clearly had human-like forms but ran eerily on all fours.

Their speed was incredibly fast, akin to a speeding car.

The armed personnel could only see a red blur flashing past, and in the next second, the figures were right in front of them. These red figures were incredibly strong, with sharp claws on their hands and feet, and teeth that served as lethal weapons.

Splutch! Splutch!

The armed personnel in the rear hadn't even had time to fire before their chests were pierced by elongated claws.

Their hearts ruptured, causing a torrent of blood to gush from their mouths.

These red figures frantically surged into the crowd, crawling swiftly through the sewage and leaping among the people, launching a sudden surprise attack and gruesome slaughter!

Ratatat!

The armed personnel quickly opened fire, bullets whizzing through the narrow space.

Bode's pupils contracted sharply as he slammed his palm on the table.

He suddenly realized a fatal issue.

These strange red beings were undoubtedly unleashed by the Apocalypse Society. Initially, they had not anticipated that Apocalypse Society would possess such biological weapons.

At most, they thought Apocalypse Society would have some fanatic followers armed for resistance.

The two sides would engage in a firefight within the underground sewers.

But this situation, this surprise attack was far too unexpected, throwing the soldiers into panic, firing intensely. Although it could effectively repel these unknown creatures, the tight space and dim lighting made accurate aiming nearly impossible.

Facing the encroachment of unknown creatures, in their terror and the urge to protect themselves, no one's finger relaxed on the trigger.

This could provide powerful firepower but also brought substantial threats.

In the cramped space, stray bullets posed a significant risk of injuring fellow comrades!

Sure enough, Bode could clearly see in the footage that seven or eight armed personnel from the security squad weren't killed by these unknown creatures but fell victim to errant gunfire from their companions. Bullets reflected off walls, striking their bodies.

"Calm down! Everyone calm down! Organize a fire defense line!"

Bode shouted loudly, attempting to calm the soldiers on Erin's side, yet the earpiece transmitted even more chaotic sounds.

He looked to the other side of the video where Fang Jinpeng and Liu San were also beset by unknown creature attacks.

Numerous red unknown creatures gushed from all directions in the sewer, assaulting the three strike teams.

Bode immediately shouted, "Support team! Move in for support! Bring electric crossbows!"

The electric crossbow is a powerful new weapon capable of firing crossbow arrows with high-voltage electricity—a force capable of instantaneously electrocuting even an elephant to ashes.

Bode already realized that bullets inflicted minimal damage on these unknown creatures, as many had been hit by seven or eight bullets and could still withstand heavy firepower and attack his soldiers.

If bullets had such low effectiveness, they would resort to high-voltage electricity!

"Erin! Fang Jinpeng! Liu San! Protect your soldiers!"

Bode's voice reached the ears of the three captains, Erin's face displaying a grim and angry expression, her pupils narrowing sharply, and an intense scream emanating from her throat.

A large number of scales began to cover the surface of her skin, especially her hands, becoming akin to some lizard paws, covered with scales and sharp claws.

This was the effect of the biological calamity.

It resembled the demonization in the third stage of the Banshee Calamity.

Anger surged within Erin, her strength multiplied, altering her speed dramatically, becoming faster than those red unknown creatures as she charged into the crowd.

As one unknown red creature attempted to extract the heart of an armed personnel, Erin appeared instantly at its side, launching an attack by extending an arm and effortlessly piercing the red creature's body, crushing a heart with a fierce squeeze.

The red creature instantly became inert.

Several red creatures sensed Erin's danger and simultaneously attacked. Three red creatures lunged at her but were all kicked away by Erin.

The powerful force sent the three red creatures crashing heavily against the wall, creating cracks in the wall!

Erin, in the midst of biological calamity, underwent the Flesh and Blood Calamity.

Within the extraordinary humans in the Wasteland world, combining Flesh and Blood Calamity with biological calamity was commonplace due to their high complementarity.

Biological calamity can be understood as transplanting superior parts from other creatures. The scales on Erin, for instance, were cultivated from snake genes and transplanted onto humans, enhanced through consuming other humans.

Upon reaching perfection, these scales can be harvested from the cultivators and transplanted onto lovers, hidden beneath the skin, able to manifest at any time. These scales are harder than steel, capable of withstanding direct bullet shots.
