Quick Transmigration: I'm the Villain's Assistant to the Protagonist

Kaka knew he had to deal with this threat as soon as possible in order to continue searching for a passage.

He whispered to Shen Ying behind him, "Be careful, I'll hold it off."

As he spoke, Kaka cast a powerful binding spell, briefly binding the leopard's limbs with magical ropes.

Kaka seized the opportunity to unleash a series of attack spells on the demonic leopard. The demonic leopard roared, and its dark aura surged, breaking free from its restraints.

Just then, good news came from Eric's side: "Found it! There's a hidden door here, which should be the passage to the sealed place."

Kaka was overjoyed, but the leopard pounced again.

Kaka gritted his teeth, gathered all his magic power, and unleashed a dazzling beam of light magic. The light temporarily blinded the demon leopard, which roared in pain.

Kaka took the opportunity to retreat to the hidden door and entered with his companions. He then used magic to close the hidden door, temporarily escaping the pursuit of the demon leopard.

The group dared not stop and continued forward along the passage behind the hidden door.

The group continued along the passage when suddenly, large amounts of black smoke billowed from the surrounding walls. This smoke quickly condensed into various ferocious monsters, baring their fangs and claws as they pounced on them.

The entire space was filled with the roars of monsters, and the scene instantly descended into extreme chaos.

Shen Ying focused intently on dealing with the monsters before her, unleashing beams of bright magic as she engaged in fierce combat with the hideous creatures.

The monsters charged forward relentlessly. Shen Ying's forehead was covered in sweat, but her eyes remained resolute. She was completely unaware that a giant tentacle formed from smoke was silently and ghostly reaching out towards her from behind.

The tentacles snaked forward in the darkness, carrying a deadly threat.

While fighting the monsters around him, Kaka kept an eye on Shen Ying out of the corner of his eye.

When his gaze fell upon the terrifying tentacle behind Shen Ying, his pupils constricted sharply, and his heart felt as if it were being gripped tightly by an invisible hand, filling him with anxiety.

He wanted to shout to remind Shen Ying, but the surrounding noise almost drowned out his voice.

He tried to rush over, but several monsters clung to him like maggots, making it difficult for him to break free.

The tentacles drew ever closer to Shen Ying, almost touching her hair. At this critical moment, the dark magic that Kaka had been suppressing within him erupted like a surging tide.

In an instant, he was surrounded by a dense black light, within which black lightning flickered faintly.

His blue eyes flashed with an eerie purple light, as if gazing from the abyss, containing boundless power and a barely perceptible struggle.

As the dark magic erupted, powerful magical fluctuations rippled outwards from Kaka as the center.

This fluctuation was like a storm; wherever it went, those originally menacing monsters were instantly blasted away like fragile pieces of paper.

Some monsters were shattered into dust, turning into wisps of black smoke; others were slammed against the walls, collapsing to the ground with a dull thud.

However, this powerful surge of dark magic triggered an even stronger reaction within the ruins.

The walls trembled violently, bricks fell, and dust flew everywhere.

More black smoke billowed out from all directions, converging into a ferocious giant shadow with red eyes flashing with rage and its mouth wide open in a roar, quickly filling the entire space. This was the fury released by the defense mechanism of the ruins being triggered.

Shen Ying, knocked to the ground by the impact of the monster, looked at Kaka with disbelief, her eyes filled with shock and confusion, unable to understand why Kaka possessed such terrifying dark power.

Shen Ying looked at Kaka in surprise, her eyes filled with disbelief.

"Kaka, you..." Her voice trembled slightly.

Under the powerful shockwave generated by the magical impact, Kaka's hood was suddenly ripped off, and at the same time, the metal mask that had been completely covering his face gradually developed spiderweb-like cracks under the violent onslaught of the magic.

With a crisp "clang," the mask fell to the ground, kicking up a small cloud of dust.

His snow-white hair stood out in the darkness, like a shimmering galaxy in the night sky, each strand radiating a mysterious glow.

The blue eyes were deep and captivating, like a tranquil deep sea, but the faint purple light flashing within them at this moment was like a mysterious whirlpool hidden beneath the surface, full of unknowns and dangers.

His face was as handsome as a god in ancient Greek mythology, with distinct lines and every contour as if it had been carefully sculpted.

Beneath his high, straight nose, his slightly pursed lips carried a hint of coldness.

Eric stared wide-eyed at Kaka's white hair, the purple light flashing in his blue eyes, and his cold and handsome face, a chill running through him.

The powerful dark energy that Kaka unleashed was like a surging tide in the night, and its unique magical fluctuation frequency was like a unique and mysterious melody.

Add to that Kaka's highly recognizable physical features, and the three intertwined like three precise keys, instantly unlocking the door to Eric's memories. He immediately recognized the person before him as the awe-inspiring and infamous dark magician Cassius, whose name had been whispered in countless terrifying legends and was a symbol of fear in people's hearts.

"Cassius!" Eric exclaimed in surprise, his voice hoarse with shock.

Lillian also looked surprised, her eyes wide open, her lips slightly parted, her face full of disbelief.

When Shen Ying heard Eric call Kaka Cassius, her jaw nearly dropped. Her eyes widened in disbelief and confusion. The villain she had been thinking about all day, the dark magician Cassius, was actually Kaka?

Shen Ying stood there stunned, her feelings a jumble of emotions, too complex to describe.

She felt her mind go completely blank.

For a fleeting moment, she felt a sense of absurdity.

Not long ago, she was worried about not being able to meet Cassius and fearing that she would not be able to complete her mission. But now, dramatically, Cassius has been right beside her all along.

Looking back, he truly never lied to himself.

She had never mentioned the name Cassius to him, but subjectively assumed that he was Kaka, and he had never denied it.

Maybe Kaka really is his nickname?

Shen Ying tried to sort out her emotions, but the shock, realization, and relief were all intertwined and tangled in her heart, making it impossible for her to describe the complex feelings she was experiencing.
