The warning siren blared through the isolation zone just as two guards finished their shift change.

[Warning! Warning! General Ares Hayes has broken containment!]

[Isolation Sector lockdown imminent! All personnel below S-Rank evacuate immediately! S-Rank males prepare for combat!]

The guards' faces went pale. They tried to flee, but a massive black wolf appeared before them.

In a flash, their transport was struck by lightning emanating from the beast's body. Both guards were killed instantly, their bodies burned to ash.

But the girl in the back seat? Not a scratch. She tumbled from the wreckage, rolling over twice across the ground before her hazel eyes snapped open.

"...Ouch."

Elena groaned, her forehead wrinkling as pain coursed through her body.

A robotic voice spoke in her head.

[Host successfully transported to the Beast World.

Current Identity: Female Leopard-Cat Tribe, 18 years old.

Physical Constitution: F-Rank.

Mental Power: F-Rank (adjusted to Unlimited).]

[Main Mission initiated: Claim the Wolf General-Successfully soothe and mark Ares Hayes. Mission completion will unlock 10% system progress.]

Where am I?

The System's transmission quickly answered her question.

She had been reborn into the interstellar Beast World, as a young adult female of the Leopard-Cat Tribe. She had no reproductive ability, and her mental power was the lowest rank.

Her original self had volunteered for a dangerous job helping the mentally unstable Imperial General. Her grandmother's illness had left her desperate for funds. She had been promised ten million star coins, but the work was deadly.

Ares Hayes, known as the Empire's War God, was the designated next Marshal. His mental power ranked at the highest 4S level, and the stronger a beastman's mental power, the more destructive he became when unstable.

The original Elena had died immediately upon entering the isolation zone, unable to survive the General's psychic assault.

Now, the reborn Elena had to face him.

"System, what benefits come with reaching 100% progress?" Elena inquired.

[Each time you successfully bond with a System-designated male, progress will unlock. When you successfully help resolve the Beast World's reproduction and stability crisis and reach 100%, you will receive the Key of Space-Time, granting you one opportunity to return to a critical point in your original world and change your fate.]

Elena's heart raced. "You mean I can go back to before I was killed?"

[Yes, Host.]

Thoughts of her parents, the child who would never be born, and the faces of Marcus and Victoria filled her with rage. Elena clenched her fists. She would survive, complete her mission, and return for vengeance.

[Current progress: 0%. Good luck, Host.]

Elena rose, and a massive black wolf descended from above, the impact shaking the ground beneath her.

At roughly ten feet tall, with powerful limbs and golden, feral eyes, the wolf dwarfed her.

It unleashed a thick bolt of purple lightning. The energy gouged a four-meter-deep crater in the earth, yet it dissipated harmlessly across Elena, thanks to the System shielding her.

Seeing the wolf preparing to attack again, Elena set aside fear. Following the original Elena's memories and the System's guidance, she rushed to its side and placed her hands against its soft fur, releasing her mental power outward.

Enhanced by the System, her power surged into Ares like a tidal wave. Gradually, the golden feral light in his eyes softened. His massive form shrank into a half-human, half-wolf state.

Elena looked up at the towering figure before her, heart skipping a beat.

In his semi-beast state, Ares stood nearly seven feet tall, naked, with jet-black hair and piercing green eyes. His angular features were sharply sculpted, perfect in every line.

Elena forgot how to breathe. She tried to look away but found her gaze traveling downward instead. Bronze-toned skin covered broad shoulders marked with scars, a firm chest and chiseled abs. His long, powerful legs supported his frame, and between them...

Elena quickly looked away, shocked.

It was frankly not a size any human man should ever possess.

She forced her attention back to pacifying him, though the twitching black wolf ears atop his head and the fuzzy tail swaying gently behind him kept drawing her eyes.

The changing eye color indicated that Ares was stabilizing. Just as Elena anticipated his full recovery, she found herself suddenly swept up in powerful arms and cradled against his chest.

Elena pressed her hands against his broad chest, nervously calling out, "General Ares.?"

So close, she caught the minty scent of him. Strangely comforting.

Ares blinked at her voice, briefly lucid, but confusion returned. He didn't remember what "Ares" or "General" meant.

All he knew was that the female in his arms was beautiful. She had striking gray-brown eyes, a delicate nose, and tempting lips.

Most of all, she smelled like peaches, awakening his most primal desires.

Ares lowered his head, nuzzling her cheek, his hand stroking her back.

Elena hadn't expected this intimate gesture. As a Leopard-Cat, her back was sensitive; the touch sent electricity shooting through her body.

Impulses surged, and she leaned instinctively against his broad chest.

Reason told her to resist, but her body craved contact.

"What's happening..." Elena moaned softly.

Her soft voice sounded irresistible to Ares. His golden beast eyes flickered with desire. Her scent, her voice, her warmth-all triggered something possessive deep inside him.

Confusion clouded his mind. He didn't know what these feelings meant.

Just as Ares leaned in to kiss Elena, he smelled other male beastmen approaching. His pupils turned to slits.

Male beastmen. Many of them. They would steal my female! Protect her!

Instinct overwhelmed Ares. He held Elena tight and dashed toward the dense forest.

Even 4S-level males couldn't match his speed. The group sent to sedate him only caught a glimpse of his departing shadow.

"The General has regained his semi-human form? Has he regained reason? Report to Her Majesty immediately!"

"There's a female scent. did he take the girl?"

"No way! Did the General take her for mating? But General Ares has always believed in fated mates and never touches other females."

"I heard he relies on suppressants during his heat cycles. His mental breakdown happened because he's been suppressing his needs too long."

Once male beastmen started talking, the conversation inevitably turned sexual, especially when discussing someone of high rank and authority.

Ares had long been a celebrity in the Empire, constantly avoiding female attention by claiming to be waiting for his fated mate.

Meanwhile, Elena had been taken to a secluded cave.

The moment they landed, Ares pressed close. His breathing quickened, his body temperature rising. Fingers traced her lips, and he kissed her demandingly, hungrily claiming her mouth.

Every touch sent electric shocks through both their bodies. Ares craved more contact, and Elena felt the same pull.

In his eagerness, Ares's fangs accidentally cut Elena's lip.

Trapped under his weight, Elena tasted blood on her tongue.

Pain mingled with the System warnings blaring in her mind.

[Warning! Target is unexpectedly entering heat cycle. Host must complete marking, or the target faces total mental collapse and death.]

[Mission failure will result in Host termination-death. Act now!]

Elena froze, quickly realizing the situation. She had successfully soothed him, but Ares was unexpectedly entering his heat cycle. If she didn't act, he could die, and failure would erase her.

She had no choice.

Males in heat could only find relief through mating with a female.

Marking would completely restore the male's sanity, but it required the female's mental power to entwine with the male's during intercourse, releasing all his turbulent mental power.

Elena's gaze swept over Ares's massive form, towering and frighteningly powerful, and her throat went dry. She swallowed hard and drew a trembling breath before kissing Ares back.

Ares sensed her initiative. He deepened the kiss, his tongue forcefully parting her teeth and tangling with hers in raw hunger. His scorching breath fanned across her face, the mint scent intoxicating her senses.

Ares trailed kisses from her mouth to her neck, teeth scraping against her skin. Since he had been in his beast form earlier, he remained completely naked. Elena could feel his rock-hard cock pressing urgently against her private part.

His shaft was large and burning hot. As he moved, it brushed against her folds, sending waves of tingling pleasure through her body that made her knees weak. She could feel herself growing wet, though she knew that minimal moisture would never be enough to accommodate his thick length.

Ares pinned her beneath him, completely out of control. Every muscle in his body was rigid, his skin burning with fever. His huge cock pressed against her entrance.

No. This body is still a virgin.

Elena managed this clear thought despite his suffocating kisses. She needed to make him release some tension first, and she needed to... prepare herself.

While he buried his face in her neck, licking and biting, Elena reached down with trembling hands. She touched his solid abdomen, then grasped his hot, hard length. Ares immediately let out a satisfied, urgent growl from deep in his throat, thrusting forward into her touch.

His cock was fully exposed before her eyes now, its tip glistening and wet. A powerful male scent filled her nostrils.

No time for hesitation or embarrassment. Elena took a breath, lowered her head, and took his tip into her mouth.

"Mmph..."

Too big. The head stretched her mouth open, pressing down on her tongue as it pushed deeper. She could only take half before her jaw ached unbearably. She worked diligently on what she could manage, swirling her tongue around the tip and sucking hard at the small opening.

Above her, Ares's breathing grew heavy with pleasure.

But it wasn't enough. A large hand suddenly gripped her hair, forcing her head down!

"Gah! Ngh..." His cockhead slammed into the back of her throat.

Elena instantly couldn't breathe. Tears sprang to her eyes as all sounds were choked off. Her throat constricted around the intrusion by reflex, squeezing him tighter. This sensation clearly drove Ares wild-he bucked his hips, beginning to thrust into her mouth.

Elena could only make muffled whimpers as he used her.

Just as her vision started getting spotty, Ares seemed to remember "don't break her yet" and pulled out. Sticky fluid connected to the corner of her mouth as he growled hoarsely, "Open."

Elena tilted her face up, opening her swollen lips. Ares stroked his veiny cock rapidly with his hand. After a few quick pumps, thick streams of cum shot onto her face and into her waiting mouth.

The sight of Elena like this seemed to greatly please Ares's primal side.

He growled, pulling her up from the ground and holding her tightly against him, his large hands massaging her numb knees. But this moment of "tenderness" lasted only a second. In the next, he laid her down on the fur-covered floor and tore off what remained of her clothing.

Elena knew the Ares before her now had only "penetration" and "release" in mind-foreplay wasn't an option.

While he buried his face against her chest, greedily sucking and biting her hardened nipple while his hand roughly kneaded her other breast, Elena slid her hand between her legs.

She was already soaking wet. She carefully put one finger into her tight entrance.

It hurt a little, but the deeper sensation of emptiness and craving overwhelmed the discomfort. She gently moved her finger, trying to relax while searching for spots that would make her wetter. Soon, more slick arousal flowed out, coating her fingers.

That should help...

She thought as she withdrew her hand.

Ares's desire clearly hadn't been satisfied by the oral release-his cock stood just as hard, perhaps even more erect than before.

He spread her legs and positioned his tip against her slick wet pussy.

No pause, no asking permission.

With one powerful thrust, Ares drove inside, using brute strength and the little wetness she'd managed to make!

"AHHH!" Tearing pain instantly shot through her entire body.

Elena screamed, her nails digging deep into Ares's back.

So hot! So painful!

Being filled by that wild, rock-hard cock-the burning heat and rough stretching made her body shake uncontrollably.

Ares panted heavily, clearly uncomfortable.

Entry was difficult; she was too tight.

Elena's instinctive contraction from pain only squeezed him tighter, causing both to groan in discomfort.

The wild Ares didn't understand why getting inside was so hard. He growled in frustration but started thrusting roughly with the little progress he'd made.

Each thrust brought new pain, making her lower stomach hurt badly. Sometimes, his thick head would brush a certain spot inside her, sending sharp electric jolts through her body, but these were quickly overwhelmed by more intense pain.

After what felt like forever, with all the friction and pressure, Elena felt herself getting wetter-her own arousal mixed with what might be blood from the rubbing.

She endured the pain and glanced down. What she saw made her scalp tingle: his massive shaft was buried inside her, stretching her delicate opening to a pale white. The tender flesh was pulled out and pushed back in with each thrust. A shocking length remained outside, the purple-red stem coated with their mixed fluids, his sack below swollen like a sandbag.

Watching herself being taken, the visual intensified the physical sensation. It still hurt, but a strange excitement of being completely filled and possessed emerged from deep within her. Involuntarily, she tightened her pussy, her inner walls starting to eagerly grip his enormous member as more wetness flowed.

Ares immediately felt the change. A satisfied growl rumbled in his throat as he suddenly increased his pace, each thrust more powerful than the last, drilling deep inside her.

Elena bit her lip, attempting to hold back her moans, but it was impossible. An intense spasm of mingled pain and extreme pleasure washed over her. Her vision went white as her core convulsed uncontrollably, releasing a flood of wetness that soaked the fur beneath them.

She was stunned to realize she had climaxed from such brutal sex.

Ares pulled his cock from her vagina, his eyes darkening as he admired her pulsing entrance still contracting after her climax.

Her thighs trembled uncontrollably, but his desire was far from satisfied-his cock remained hard, jutting upward demandingly.

Without warning, he pressed down on her again, folding her legs back against her chest, exposing her completely. This time, there was no hesitation as he drove his entire length into her in one brutal thrust, slamming against her cervix.

"No-wait-AH!" Elena's pleas shattered into broken cries.

Holding her nearly folded in half, Ares began ruthlessly pounding into her. After several savage thrusts, her cervix gave way, allowing him even deeper access.

"AAAGH!" Elena screamed, her voice breaking. Her stomach visibly bulged with each thrust, letting her feel every movement of his cock as it ravaged her deepest parts. Ares placed his palm on her flat stomach, as if wanting to feel himself moving inside her.

He varied his angles and depth-sometimes withdrawing completely before slamming back in, sometimes grinding against her tender inner walls with quick, shallow thrusts. The mixture of unbearable pain and primal pleasure threatened to tear Elena's consciousness apart. Every impact forced broken whimpers from her throat.

When the pain seemed endless, Elena had only one thought left: make it stop.

Now, the only way to end this torment seemed to be making him come.

Fighting through the aching soreness that threatened to tear her body apart and the dizziness clouding her mind, she struggled to move her hips on the rough fur beneath them. Her slick inner walls contracted desperately around him as she begged between sobs, "Cum inside me... please... fill me up..."

Ares paused briefly before unleashing an even more violent assault. After dozens of merciless thrusts, he growled deeply and flooded her newly opened womb with hot spurts of cum.

At the exact moment of his release, Elena felt the base of his cock swell dramatically inside her-a hot, hard knot rapidly expanding, locking her in place as it stretched her entrance beyond what she thought possible.

"No! Too much... AH!" She cried out at this new, more intense pressure. Massive amounts of semen pumped into her deepest parts with nowhere to escape, visibly swelling her lower belly.

Ares released a satisfied, low whimper, trembling as he pulled her closer. Even after finishing, his instincts drove him to press forward, ensuring his knot was buried as deeply as possible, trapping every drop of his seed inside her.

Now!

With their bodies completely joined and locked together, Elena fought through the stretching pain and dizziness. She turned her head sharply and sank her teeth into Ares's exposed neck, her small fangs breaking his skin.

A sharp pain made Ares's body stiffen. A rumbling growl vibrated in his throat, but instead of pushing her away, he held her tighter, as if accepting this deeper confirmation of their bond.

Simultaneously, Elena closed her eyes and concentrated every remaining ounce of strength to thrust her mental power into Ares's chaotic mental consciousness.

In their shared mental consciousness, her spiritual form manifested as an agile, alert leopard cat. At the center of the primal, storm-like mental terrain crouched a massive, majestic black wolf with burning eyes.

The leopard cat ran directly toward the wolf. Instead of the expected violent clash, the wolf simply lowered its head, touching its wet nose to the smaller cat, then extended its rough, broad tongue to lick the cat's fur with intimate, soothing strokes.

An indescribable comfort and sense of connection washed through Elena's entire body with each mental contact.

As their mental power began to intertwine uncontrollably, Elena felt Ares's immense, furry wolf tail possessively wrap around her body.

"Mmm..." A deep, satisfied sigh rumbled from Ares's throat, echoing directly in her ear and throughout her mental consciousness.

The sound was almost magical. Elena's mind went blank as she sank into a warm, soft cloud of sensation.

Intense pleasure exploded from the depths of her soul, washing away most of the pain and exhaustion.

Sweat dripped down her face as her flushed cheeks and dazed eyes showed exactly how she felt. She couldn't help gently licking the bleeding bite mark she'd left on his neck, a permanent sign of their bond.

After they joined both physically and mentally, Elena's mental power deliberately left a small piece of itself in Ares's mental consciousness. That tiny, warm, playful light lovingly rubbed against the black wolf's chin before curling up next to his huge form and making itself at home.

The marking was complete.

Elena slowly pulled the rest of her mental power back. As the last connection to Ares's mental consciousness broke, crushing emptiness and weakness hit her. Her body went limp, too weak to even lift a finger, only able to lie in Ares's still-burning embrace, feeling his knot pulsing deep inside her.

Just then, the familiar robotic voice of the system spoke in her head.

[Congratulations, host. First mission objective successfully completed.]

[Mission evaluation: Perfect. Successfully soothe and mark Ares Hayes.]

[Skill unlocked: 'Self-Healing Ability Lv.1.' Host's physical damage can now self-repair, physical constitution greatly enhanced to B level. Skill can be upgraded through further mission completion.]

[System authority unlock progress: 10%. Function Unlocked: Active Conversation Mode]

Elena sighed with relief. She would live.

About fifteen minutes later, Elena felt the knot inside her gradually receding as Ares's body temperature slowly returned to normal.

Still dazed, she noticed Ares suddenly stiffen beside her as he carefully moved away.

His green eyes still held traces of desire, his tanned skin flushed and sweat trailing down his muscled chest. But when he looked at her, his expression hardened with anger.

"Damn it! You marked me?!"
