A trace.

Even the slightest external interference that invades a person's mental sea will trigger a violent rejection reaction!

Mild cases may result in splitting headaches, nausea, and vomiting; severe cases may lead to mental confusion and even death on the spot!

As for raising another complete spiritual entity within the human mind? That's utterly a fantasy, a rumor that defies the laws of life!

However, Li Yu's mental state is just like that, defying common sense.

The Nightmare Beast seems to have made Li Yu's mental sea its home, completely refusing to allow any other mental intrusion:

"How dare you! You dare to act wildly on my turf?!"

After struggling in the waves for a while, the Nightmare Beast finally came to its full senses, completely enraged by the relentless waves!

His black eyes narrowed sharply, and he steadied himself with a forceful movement.

"Certainly--!!!"

A voice filled with anger resounded throughout Li Yu's mental space!

With just one word, the Nightmare Beast froze the black tides and the condensed water spears.

Immediately afterwards, the white mist on the Nightmare Beast's body suddenly erupted, sweeping past with a storm that purified everything!

The sea monster's all-pervasive sonic attack was completely and utterly crushed by the Nightmare Beast in Li Yu's mental sea, instantly clearing it out without leaving even a ripple!

The remaining giant waves of seawater quickly disintegrated, forcibly transformed by the Nightmare Beast, and dissolved into Li Yu's mental sea.

In the real world, it's a matter of life and death!

Li Yu suddenly opened her tightly closed eyes, her gaze sharpening instantly! Her consciousness returned to normal in a flash.

Faced with the imminent extreme danger, the speed of the cyclone in his abdomen instantly soared to its limit!

Everything around me slowed down dramatically, and my body instinctively retreated to its limit!

"Thump!!"

Almost at the same instant, the sea monster's foot, powerful enough to crush mountains, slammed down on the spot where Li Yu had been standing just a second before!

The ground instantly collapsed, creating a huge crater more than ten meters deep, and rainwater, along with rubble, shot into the sky under the pressure!

The cracks in the surrounding earth were enough to demonstrate just how astonishing the force of the sea monster's kick was.

Sensing Li Yu's return, Oldman, who was 'cleaning up' a large number of First Legion soldiers in the distance, suddenly turned around:

"What?!"

The wolf's face was filled with extreme shock and disbelief: "He's not dead?! How could he have broken free from the 'Sea God's Whispers'?!"

Even he was wary of the mental attacks of this sea beast!

The sea monster's last remaining giant eye widened suddenly, its countless scarlet compound eyes locking onto Li Yu, who had dodged away, filled with astonishment and suspicion.

At the same time, the dark eye on the phoenix bow in Li Yu's hand opened instantly, burning with tangible rage.

After scanning the area, the Nightmare Beast's gaze finally settled on the large creature in front of it that had given it a "cold bath" and stabbed it with a spear, its eyes blazing with fury!

"Hey kid! Just because you're big doesn't mean you can be all-powerful. You think you can do whatever you want in the spiritual realm just because you're big?"

The vengeful Nightmare Beast couldn't stand this insult and vowed revenge immediately! Not even the next day.

"Today I'll show you what a real mental attack is! It's not something that just because someone is bigger can be stronger."

"Let you experience what it's like to be mentally attacked!"

As it spoke, the Nightmare Beast began to gather its power, and white mist immediately swirled around the Phoenix Bow. Then it glared at the enemy.

"magical--!"

The moment the Nightmare Beast looked over, an invisible and intangible yet terrifying mental shockwave, powerful enough to distort the perception of reality, completely ignored the physical defense of the scales, instantly crossed space, and slammed into the sea beast's compound eyes, which had just regained their intelligence and were still filled with surprise and doubt!

"Ugh...?!"

The sea monster's massive, mountain-like body suddenly stiffened! Its only eye momentarily lost focus, and the continuous low-frequency sonic attack abruptly ceased, like a string on a musical instrument severed by a sharp blade.

The cold light of wisdom in his eyes was instantly replaced by chaos, and then his body swayed slightly uncontrollably, as if he were drunk or trapped in the deepest nightmare.

The low-frequency sound waves that enveloped the battlefield fell silent, and the suffocating pressure from the deep sea and the mental illusion also dissipated rapidly like the receding tide under the Nightmare Beast's counterattack.

The terrifying waves that had invaded everyone's minds, along with the hallucinations, vanished instantly.

"Uh...ho!"

"Cough cough..."

Bai Ruyu and Bai Linzhu were the first to break free from the mental quagmire, breathing heavily and coughing, their eyes still showing the terror of being dragged and torn apart by the deep-sea monster.

Immediately following, as if in a chain reaction, the surviving soldiers of the First Legion regained consciousness, their eyes filled with the terror of surviving a catastrophe, looking around blankly.

"Uh... Ah! Wasn't I dragged to the bottom of the sea?"

"I...I'm still alive?"

"Was that an illusion?"

The soldiers, still shaken, were deathly pale. Someone instantly recalled what had just happened and shouted a warning: "Watch out! This sea monster can also use mental attacks!"

Everyone looked up and saw that the terrifying sea beast, which was as big as a mountain, was frozen in place as if it had been hit by a spell.

The remaining giant eye was filled with chaos and struggle, and its massive body trembled slightly.

It is now deeply trapped in a mental illusion created for it by the Nightmare Beast, which is far more chaotic and terrifying than the deep sea!

The balance of power was reversed in an instant!

Noticing the changes in the sea monsters, Oldman, who was in the middle of the slaughter, sensed something was wrong. He flashed back to the teleportation array, pressing his wolf claws firmly against the violently flashing array patterns, as if preparing something.

"What a pity. If we had killed a few more people, we might have been able to perform a second blood sacrifice teleportation."

"These two sea monsters will surely make Zhongzhou pay a heavy price!"

Oldman stared intently at Li Yu, who had disrupted all plans, and couldn't help but say, "Strange kid, it's unbelievable that someone with your strength can resist 'Abyssal Echo'."

It should be noted that the sea monster's sonic attack was primarily aimed at Li Yu, yet Li Yu was the first to wake up.

Li Yu just smiled slightly when he heard this. "You say it's strange, then it is. After all, sometimes I also feel that my special ability is a bit strange."

He slowly raised the phoenix bow in his hand, and flames spread silently, with a faint, high-pitched, clear phoenix cry flowing within the flames!

The target was the massive figure caught in the chaos!

On the Phoenix Bow, the Nightmare Beast's eyes flashed with a violent light as it stared intently into the sea beast's eyes, talking incessantly to Li Yu:

"Yes! Li Yu, that's it."

"Shoot it! Shoot it to pieces! I have this giant idiot completely under control!"

At this moment, the Nightmare Beast was even more excited than Li Yu, its voice filled with the thrill of impending revenge:

"You little sea monster, how dare you provoke me! Now let's see if you live or die!"

Li Yu calmed his mind and urged the vortex to operate wildly. The vast energy that had been accumulated in his body for a long time flowed into the sea like hundreds of rivers flowing into the sea, continuously pouring into the flaming arrow that was nocked on the bowstring!

The burning golden-red tip of the arrow gradually turned into a point of golden light, so dazzling that it seemed to pierce the sky!
