The severed arm in the pool of blood is a forearm, cut off at the elbow, connected to a pale hand.

The forearm is approximately 30 centimeters in length, slender in form, the skin pink, with a very delicate surface, most likely the arm of a young girl.

The hand is equally slender, with an unhealthy scrawny look. Though there's a bit of flesh, it's not quite a "skeletal frame", but not far from it either.

On the back of the hand is an unobtrusive red pattern, depicted in "simple line art", showing a silver eye, giving it a mysterious feel.

However, with severe blood loss, this eye also lost its original vitality, becoming lifeless just like the arm it clings to.

Undoubtedly, this is Aurora Miles' right arm, a torn-off limb, evidenced by the beast-like bite marks.

If this is the state of the arm, what kind of situation is Aurora herself facing right now?

Yun You and her companions dared not imagine, nor had the time to ponder.

Because the perpetrator of all this had already arrived behind them.

Thud! Thud! Thud——

The monster's footsteps were tremendously heavy, each step causing an industrial hammer-like thud, making the entire laboratory shake repeatedly.

Its breath was also rough, with a "hiss" emitted every two seconds, spewing high-temperature, high-pressure hot gas, unknowingly heating the surrounding environment and even igniting the particles in the air, sparking small fires.

"Gulp..."

Yun You and her companions swallowed simultaneously.

They clenched their fists, mentally preparing for everything, and then slowly turned around to gaze upon the enormous figure.

Thus, a true monster presented itself before them.

What an exaggerated monster it was...

Its body was entirely black, as large as a bear, standing at a height of four meters, nearly touching the ceiling of the corridor, resembling a massive black iron door.

It generally had a humanoid form, with human-like limbs, each as thick as tree trunks, but it had no head; above the neck was just an empty space with a small opening similar to a throat, leading directly to the abdominal cavity.

The monster's abdomen was the strangest part, with a human head-sized heart embedded exposingly at the chest, surrounded by twisted muscles and blood vessels. Below the heart was a wide, mouth-like transverse wound, stretching from the left shoulder to the right waist...

The wound was filled with malformed sharp teeth, constantly grinding together, exuding a strong bloody smell, oozing along with high-pressure steam and meat chunks, sending chills down one's spine.

Clearly, this was the biological weapon Xie Kang, a researcher, developed using the "Undying Heart" as a medium.

With its own power, it destroyed the institute's entire defense system, massacring all researchers and devoured their flesh and blood.

In one of the monster's hands, Yun You vaguely saw a small tuft of hair.

Blood-stained golden hair.

It belonged to Aurora.

"...!"

Seeing this soft lock of hair, Yun You felt a tug in her heart, a sense of sadness inconspicuously surfacing in her mind.

Aurora, the girl who had been providing information and help from the beginning, ultimately succumbed here, her fate grim.

Yun You should have anticipated this.

That girl didn't inherently possess great combat abilities, and was frail as well, usually keeping a low profile. If she encountered this monster in the laboratory, she was almost certainly doomed, with no chance to escape.

By now, she had most likely become a meal inside the monster's belly...

But then again, Yun You didn't have much time to mourn for this girl at the moment.

If they didn't do something, they would follow in Aurora's footsteps.

"Heavy firepower deployment complete!"

During Yun You's contemplation, Jack had already taken action first, pulling out weapon components from his backpack, quickly assembling an automatic machine gun on the spot, and then pulling out a portable rocket launcher, aiming them at the monster.

Meanwhile, Frost Moon closed her eyes, her neural chip operating at lightning speed, constructing an electronic virus at the code level, attempting to hack into the Headless Giant's chip.

Given it was a creature genetically modified via modern means, it must have various chips and circuits within, theoretically hackable.

Nonetheless, Yun You still acted first before the other two did.

She took a deep breath, her heart thumped heavily—

"Buzz...!"

Instantly, the "Sur Particles" in her subconscious soul ignited fervently, forming a faint blue halo around her body.

This was a sign of the Apprentice Death God activating her ability!

[Future Sight · Activated]

The next moment, Yun You's perspective jumped 35 seconds into the future just before the duo.

Old Jin had once told Yun You that the most powerful aspect of Future Sight was its "intelligence gathering" capability.

Within half a minute to a minute's foresight, the little girl could probe the enemy at will, with no consequences, learning about their traits and abilities.

Based on the principle "the essence of battles between superpowered beings is intelligence warfare", Future Sight, which allows for zero-cost intelligence gathering, could almost be deemed one of the top-tier talents...!

And now, Yun You was utilizing these 35 seconds to probe the monster as much as possible.

She first had Jack open fire at full force.

The silver machine gun spewed a stream of fire, the custom armor-piercing incendiary rounds hitting the Headless Giant precisely, aided by modern fire control.

Yet, unbelievably, the bullets, capable of penetrating an 80-mm homogeneous steel plate, failed to pierce the monster's flesh upon impact, sparking upon contact!

Its skin's defense power exceeded that of police-level special armored vehicles.

Witnessing this absurd scene, Jack in the Future Sight was naturally astonished.

But being a professional mercenary, despite his brief shock, he quickly reacted, pulling the trigger on the rocket launcher.

The RPG he used was an armor-piercing explosive specifically for armored units, utilizing chemical energy to shoot a metal jet upon detonation, penetrating over 300 mm, typically categorized as "regulated weapons."

Yet even such contraband failed to deal significant damage to the giant.

The metal jet burned through its skin but lodged firmly within the muscle, unable to penetrate even an inch further.

And once the scorching metal solidified, the Headless Giant merely gave a light shake, dislodging the metal rod.

These two tests proved that conventional weapons were almost completely ineffective against this monster.

At least the conventional weapons Yun You and her companions carried couldn't kill it.
