Chapter 1526 Brainwave Control, Invincible in Close Combat

Chen Jun's icy voice, seemingly emanating from the deepest abyss, was like an invisible awl, piercing the already crumbling mental barriers of the two "Abyss" survivors.

“Tell me the location of the entrance, and you… will be freed.”

This statement may not be effective for mentally sound individuals, but for these two people who have been repeatedly ravaged by fear, hallucinations, and hypnosis, and whose minds are on the verge of collapse, it is like a paradoxical and tempting pardon.

The word "liberation" sounded far more appealing to them at that moment than "freedom" or "survival," as it meant an end to this boundless fear and suffering.

Their eyes darted around in a fierce struggle, their facial muscles contorted. They glanced at each other, both seeing the same bewilderment, pain, and a sliver of longing for an "end." Reason had long since vanished; their remaining consciousness, caught between "continuing to endure this hellish fear" and "getting a clear answer, even if it leads to death," instinctively skewed towards the latter.

Finally, under the relentless, tangible pressure of Chen Jun's cold gaze, they almost simultaneously pointed with trembling fingers to an extremely hidden corner behind the bunker, on the rock face. There, between several seemingly natural boulders, was an extremely fine metallic crack that blended almost perfectly with the color and texture of the rock face; it would be very difficult to spot without specific guidance.

Chen Jun's gaze swept over that spot, and he understood immediately. It must be the edge of a carefully disguised lifting platform or a heavy-duty sealed door.

Having obtained the answer he wanted, Chen Jun's eyes remained completely calm, as if he had merely confirmed something insignificant. He slowly turned around, his back to the two dazed survivors, and strode towards the indicated entrance.

However, just as he turned and took two steps, that cold, emotionless voice drifted back like a ghost, drilling into the ears of the two men, carrying a strange, seductive rhythm:

“You…should obtain the final…relief from the war from each other’s hands.”

"Let's get started."

"Kill each other... and give each other... true freedom."

The voice seemed to possess a magical power, instantly piercing through the last vestiges of chaos in their minds. A twisted, instilled sense of "mission" and "path to liberation" filled their empty consciousness.

The last glimmer of reason in their eyes was extinguished, replaced by a frenzied, eerie, and "sacred" glint.

"Roar--!!"

One of them let out a beastly growl, bent down abruptly, and picked up a blood-stained combat knife that his companion had dropped on the ground.

The other person seemed to be provoked as well, and lunged forward with a low growl!

There was no skill, no strategy, only the most primal, savage desire to fight. The two men grappled like mad beasts, their military knives thrusting and slashing wildly, blood splattering from their bodies, staining the ground and walls red. They uttered incomprehensible hoarse sounds, as if performing a solemn ritual leading to "liberation."

Chen Jun didn't turn around, nor did he pause for a moment, heading straight for the hidden entrance. The cruel and eerie sounds of infighting behind him seemed like insignificant background noise.

He had a deeper understanding of the power of this "hacker hypnosis".

"Indeed...terrifying." Chen Jun muttered to himself, his steps steady. "It's not just a simple hint. It combines my almost tangible killing intent and aura, forged from countless mountains of corpses and seas of blood, with this technology that directly interferes with brainwaves..."

He narrowed his eyes slightly.

"At close range, against targets with weak willpower, it's practically an unsolvable weapon of mental destruction. It directly dismantles the enemy at the psychological level."

As he rapidly approached the entrance, he mentally reviewed the situation. This skill has another terrifying characteristic: the "psychological damage" it causes can be long-term or even permanent. Those deeply affected, especially those who ultimately descend into utter madness and self-harm, may have suffered irreversible shocks and disruptions to their nervous systems, like a tightly strung string suddenly snapping, making it difficult to restore them to their original state. This is not merely psychological trauma, but more akin to a biological level of "hardware" destruction.

"It's useful, but use it with caution. It consumes a lot of resources, and... it violates certain limits," Chen Jun reminded himself silently. This power was too strange and domineering.

Ahead, the mountain cliffs loomed large. In that hidden corner, upon closer inspection, traces of human carving and camouflage could indeed be found. An irregularly shaped opening, about three meters wide and two meters high, was cleverly designed as an extension of a natural rock fissure. The edges of the opening were framed by a thick alloy frame that matched the color of the rock, and it was now tightly closed, fitting perfectly.

The design and concealment of this entrance reminded Chen Jun of the entrances to some of the bases of the National Strategic Bureau headquarters hidden deep in the mountains. Needless to say, it must be heavily guarded and filled with unknown dangers and high technology, and perhaps even those bizarre "biochemically modified bodies".

Go in alone? Although he was confident, the risk was extremely high when facing a nest that had been operating for many years and had bizarre technology.

Chen Jun stopped, hesitated for a moment, and quickly took out a specially made signal flare from the side pocket of his tactical vest. This flare could emit extremely bright light and smoke of a specific color even in daylight.

He pulled the ring, throwing the signal flare diagonally upwards.

"Whoosh—Bang!"

With a piercing whistle, the signal flare exploded in the air, bursting forth with an extremely bright and penetrating red light, clearly visible within a five-kilometer radius even in dense forests and under daylight. Simultaneously, it released billowing yellow smoke containing a distinctive chemical composition that lingered for a long time.

This is a pre-arranged emergency assembly and orientation signal.

Less than ten minutes after the signal was given, hurried but still concealed footsteps and the sound of vegetation scraping came from the jungle on the flank. He Chenguang, Li Erniu, Wang Yanbing, Leng Feng, and the paratrooper advanced rapidly in standard tactical formation and quickly established a perimeter around Chen Jun.

When they saw that Chen Jun was unharmed and turned their gaze to the area behind him—the bodies lying haphazardly inside and outside the bunker, especially the two bodies that were intertwined in an extremely tragic and bizarre manner, clearly having killed each other, even these battle-hardened veterans couldn't help but show shock and confusion in their eyes.

He Chenguang quickly checked the surroundings, confirming that it was temporarily safe, then lowered his voice and asked with barely concealed surprise, "Boss, what's going on with these...? We've seen quite a few bodies along the way, most of them with gunshot or stab wounds, but there are several... like these two, where our own people killed each other? And... and they're still hugging each other?"

The scene was so bizarre that it went beyond the scope of normal combat.

Chen Jun looked at the undisguised confusion on their faces, simply smiled faintly, and offered no explanation.

"We'll talk about that later. Let's wait a bit until Lao Geng and the others arrive and join us."

Suppressing their curiosity, the crowd quickly took up advantageous positions and vigilantly guarded the entrance area.

About fifteen minutes later, more frequent but rhythmic footsteps and short communication confirmation tones came from the outer perimeter. Geng Jihui led the remaining "hacker" team members and Lu Da's strategic bureau group to quickly join them. They had clearly been through a fierce battle; many of them bore traces of gunpowder, and one team member had a makeshift bandage wrapped around his arm, being supported by his comrades. Fortunately, no one had been killed.

"Boss! The outer perimeter is almost cleared. We've taken out at least three patrol teams, and haven't spotted any large-scale reinforcements yet." Geng Jihui reported quickly, while his eyes warily scanned the hidden entrance. "What's the situation inside? This entrance..."

“This is one of the main entrances.” Chen Jun pointed to the cleverly disguised metal gap. “Based on the prisoners’ confessions and my judgment, the core of ‘The Abyss’ stronghold is inside this mountain, where the rock strata have likely been extensively hollowed out and altered.”

Geng Jihui's expression immediately changed. He looked at the deep, unknown entrance, then at Chen Jun, and immediately shook his head, his tone resolute:

"Boss, you're not thinking of going in alone again, are you? That's too risky! The situation inside is unknown, and it's the enemy's stronghold. You'll be alone..."

Chen Jun raised his hand, interrupting Geng Jihui, a calm smile on his face. He stepped forward and patted Geng Jihui's shoulder forcefully.

"Old Geng, don't be nervous, listen to me." Chen Jun's tone was reassuringly calm. "Precisely because the situation inside is completely unknown, the enemy is in the dark while we are in the light, and traps, troop deployments, and even those 'biological units' may be waiting in ambush inside. If a large force rushes in rashly, it will make too big a target, easily put us at a disadvantage, and cause unnecessary casualties."

He looked at Geng Jihui and the other team members who had gathered around, their faces showing worry, and continued to explain:

"I'm alone, a small target, and flexible in my movements. I can use... some special methods to conduct rapid reconnaissance and infiltration, to figure out the basic structure and defensive weaknesses inside. Once I find an opportunity, or when a strong attack is needed, I will send a signal. You guys outside aren't just waiting around; the mission is equally important."

Chen Jun's gaze swept over everyone: "Consolidate the perimeter, establish solid support and evacuation points, monitor for potential enemy reinforcements, and ensure our retreat is secure. At the same time, use equipment to attempt to probe the mountain structure from the outside, searching for other possible entrances or weak points. These are all crucial to the success or failure of the mission."

He paused, his tone becoming unquestionable:

"It's the safest and most efficient option for me to go in first and scout ahead. If you follow me in, in a completely unfamiliar and complex environment, facing an unknown defense system, you might actually become hesitant and even... a burden to me because you need to support each other."

These words were blunt, even somewhat harsh, but Geng Jihui and the others couldn't refute them. They understood Chen Jun's capabilities and knew that in extreme environments, sometimes a top-notch solo operator could be more effective than a small team, especially during reconnaissance and infiltration phases.

Geng Jihui opened his mouth, looking into Chen Jun's calm yet resolute eyes, knowing that further persuasion would be useless. He could only sigh heavily and grit his teeth, saying, "Boss... then please be very careful! If anything happens, notify us immediately! We're ready to provide backup at any time!"

"Don't worry." Chen Jun nodded, then gave his equipment a final check, stuffing the necessary small explosives, reconnaissance tools, and several special signal generators into his tactical vest. He took a deep breath and turned his gaze to the hidden entrance that resembled the mouth of a giant beast.

"Maintain communication silence and establish defenses according to Plan C. Wait for my message."

Having said that, he no longer hesitated. With a swift movement, like a cheetah blending into the shadows, he silently approached the metal gap and began to carefully examine the entrance's opening mechanism and any possible alarm devices.

Alone, I ventured deep into the lion's den.
