High-level martial arts: Contract cashback, invincible starting from the Zerg.

The five electromagnetic torpedoes, their bodies shimmering with eerie blue electricity against the backdrop of the crimson water, resembled the cold eyes of death, radiating a chilling aura of intimidation.

When the first torpedo hit its target, there was no earth-shattering explosion.

There was only a slight "buzzing" sound...

The electromagnetic adsorption device at the torpedo's tip activated instantly, and countless tiny yet resilient mechanical grippers pierced through the behemoth's armor in a flash. No matter how frantically the behemoth twisted and thrashed its body, the torpedo remained motionless, firmly embedded in its body as if rooted to the ground.

Immediately afterwards, the other four torpedoes also hit their targets.

They were evenly distributed across different parts of the behemoth, forming a tight attack array.

The next moment, the electromagnetic pulse device inside the torpedo activated, and a terrifyingly powerful electromagnetic energy rapidly gathered and expanded within the torpedo...

As five dazzling blue-white bolts of lightning burst forth from the surface of the torpedo, these bolts spread wildly outwards from the torpedo's center, instantly blooming into a giant blue lotus flower.

The lotus flower was formed from pure electromagnetic energy, its petals shimmering with dazzling light and constantly radiating powerful energy fluctuations outward.

It instantly illuminated the surrounding waters!

Just then, Chen Feng's keen ears also caught the earth-shattering roar of the Lake Spine Breaker.

The roar was like a majestic, towering mountain collapsing without warning in a moment of tranquility.

In an instant, the entire lake seemed to lose its color, and the wind and clouds changed accordingly.

Immediately afterwards, the low vibration sound was like a lit fuse.

It gradually intensified with an unstoppable momentum, like a thousand troops galloping or a surging tide roaring. Each increase was like a heavy hammer, striking Chen Feng's heart hard and making his heart beat faster involuntarily!

Finally, the roar transformed into a massive, overwhelming wave of sound, surging and sweeping in from all directions.

Wherever the sound waves passed, the water was churned up and turbulent, forming huge whirlpools;

The aquatic plants were uprooted and danced wildly in the water;

Even the solid rocky mountains trembled violently, as if they were about to collapse and shatter at any moment.

That was the boundless majesty and power of a terrestrial predator! It was also a behemoth that held supreme hunting authority over the giant beast lake, showing utter contempt for any attack!

"Senior! I'm out!!"

Bai Fei's voice, tinged with relief, came through the Lucky Contract's communication system, instantly putting Chen Feng at ease.

However, Chen Feng soon sensed that something was wrong.

The lake before them was indeed enormous, like a post-apocalyptic city that had sunk to the bottom of the water.

Faced with such a behemoth, the ability of electromagnetic adsorption torpedoes to effectively delay the enemy would inevitably be greatly reduced...

"Bai Fei, listen... We need to get the cores of those four giant beasts as soon as possible and leave this place. This Lake Spinebreaker is too big, and it's definitely after the cores," Chen Feng explained.

"Yes, sir!"

Bai Fei moved nimbly, like a forest sprite, quickly swimming towards the coordinates sent by Chen Feng.

Soon, she arrived at the body of one of the dead Mokra crocodiles.

At this moment, the waters where Bai Fei was located were murky and turbid from the blood and flesh, yet her eyes were as clear as a bright, dark blue lamp.

Two eerie blue light blades extended from Bai Fei's two-handed battle armor!

Although it was only half a decimeter long, the light blade shimmered with a cold and mysterious light.

When the light blade touched the giant crocodile's armor, it precisely cut through the armor, which was as hard as refined iron. Countless tiny cracks also appeared inside the black, hard armor, greatly weakening the target's overall strength.

The light blade sliced ​​through the thick armor as easily as cutting tofu, with no resistance whatsoever.

And finally, the blood-red core of the behemoth was revealed...

"Senior, I have obtained the first core of the Magic Kra Beast," Bai Fei said.

"Hurry, we only have one minute left."

Bai Fei was stunned.

Her beautiful eyes were fixed on the giant dragon not far away, a hint of coldness flashing in them.

"That's enough to take the cores of the other two Mokra Crocodiles."

Bai Fei's eyes hardened, and she immediately swam quickly towards another giant crocodile, raising the light blades in her hands to rapidly cut through the crocodile's armor.

...

Bai Fei had just grasped the core of the third Mokra giant crocodile in her hand, and the heavy feeling filled her with joy.

Bai Fei immediately ordered all the little octopuses that were still cleaning up the giant beast's flesh and blood to evacuate, while she herself began to swim quickly towards the lake and the island.

But at that moment, a chilling sense of unease suddenly gripped her heart!

Immediately afterwards, she felt the lake water around her become unusually heavy, as if countless invisible hands were gripping her tightly, trying to drag her into the abyss.

Her ears were ringing, and her vision went black for a moment; she almost lost consciousness.

It wasn't until a moment later, when Chen Feng's faint shouts reached her, that Bai Fei gradually regained consciousness.

"Bai...Fei!! Quickly...get...out there! Quickly!"

The voice carried endless worry and urgency, like a faint yet unwavering light guiding her through the darkness.

A buzzing sound, sharp and noisy, kept coming into Bai Fei's ears like a surging tide, as if countless wronged souls were wailing in her ear.

"senior?"

Faintly, Chen Feng's anxious shouts pierced through the layers of lake water and reached her ears.

"Bai...Fei...what...are you...doing...?!"

"It's...me..."

However, before Bai Fei's chaotic consciousness could fully clear, an indescribably powerful water pressure swept over her like a raging beast.

The next moment, a stench of blood, like a thick wall, swept over Bai Fei.

The foul stench mixed with the nauseating putrid smell made her stomach churn.

Bai Fei felt like a tiny leaf, powerless to resist this violent force.

He was instantly swept away by the water pressure, his body tumbling rapidly in the water like a kite with a broken string.

Just then, Bai Fei, finally regaining her senses, saw the end of the fierce water pressure—the rapidly enlarging figure of the Lake Spinebreaker, like a moving black mountain, and its gaping, gleaming maw...

"Damn it!!" Bai Fei quickly restarted the aquatic armor.

Chen Feng frowned, as if he had suddenly realized something.

After killing four Xuan-rank giant beasts, Chen Feng and Bai Fei's cultivation points both increased significantly, and they were only a step away from becoming Earth-rank experts and Golden Demon Slayers.

If Chen Feng and Bai Fei were to advance to the Gold-level Demon Slayer at this moment, it might be able to deter the Lake Spinebreakers and allow them to leave this place safely.

Chen Feng slowly placed his hand on the luck value, and after a moment's hesitation, he finally chose to convert it directly into experience points.

In an instant, Chen Feng's physical clone lit up with a golden light.

Bai Fei's eyes widened as she felt a new power emerging within her body.
