Inside the cave, Kai and Umbra awoke.

  The Grimoire floated closed in front of them, its energy calm.

  Kai blinked slowly, adjusting to the dim light. His body felt heavy, sluggish. The moment he tried to move, a sharp ache pulsed through his chest.

  Back in this broken body again…

  His mana channels were still strained and cracked from the battle with the centipede general. The trial had given him strength, yes, but his body hadn’t caught up yet. He needed time. Time to recover. Time to understand the new powers now resting inside him.

  Umbra stirred beside him, her eyes glowing faintly. She looked at him, then at the Grimoire, then back again.

  Without a word, they stood and left the cave.

  The moment they stepped into the massive crystal chamber, Kai felt the mana thrum in the air like a heartbeat. The walls shimmered with radiant veins of energy, and the floor pulsed beneath their feet.

  Kai exhaled slowly. “We’re back.”

  He turned to Umbra and began explaining everything: what had happened in the trial, what he’d learned, and what he’d seen of his parents.

  Umbra listened in silence.

  At first, she was in awe. Then her tail lowered, and her gaze darkened.

  “A world that forgets its own,” she murmured. “I hope I never forget you like that.”

  Kai smiled faintly. “You won’t. I won’t let it.”

  They stood in silence for a moment, the weight of everything settling between them.

  Then Kai straightened. “Let’s prepare to train. Once we recover and break through, we’ll head back. But first, food. I’ll grill some of the meat we have stored.”

  Umbra’s stomach growled in agreement. She nodded, her usual stoicism cracking just enough to show her hunger.

  Kai pulled out two massive slabs of beast meat and set up a fire using a red fire crystal and dry wood from his bracelet. The flames crackled to life, casting warm light across the crystal walls.

  The scent of roasting meat filled the chamber, rich and comforting.

  “Kai,” Umbra said thoughtfully, “that woman back there… she didn’t feel like she wanted to hurt us.”

  Kai stirred the fire, his expression still tense. “I’m not so sure. She’s hiding a lot. I get the feeling she needs me for something, but I don’t know if we need her in return.”

  His frustration was valid, and Umbra could sense it.

  “Hmm. She is strong, though,” Umbra mused.

  Kai chuckled, the tension easing slightly. “Well, yeah, she did pull me from another world, didn’t she?”

  Umbra’s occasional innocent remarks always caught him off guard.

  “No need to laugh,” she huffed, turning away.

  Kai grinned and pointed at the food. “Your meat’s done. You want to stay upset? I might eat it all.”

  Umbra turned instantly, eyes narrowing playfully. “You can try.”

  She leaned over and bit into his piece of meat.

  “Hey! That was mine!”

  “Serves you right for mocking me,” she said, chewing with satisfaction.

  Kai sighed and began preparing more food.

  They ate together, stuffing their bellies with the rich, mana-infused meal. It wasn’t just food, it was fuel. Every bite mended their bodies, stitched their wounds, and prepared them for whatever came next.

  Once they were full, they separated.

  Kai moved to one side of the chamber, Umbra to the other. They needed space. Their manas were too different. They would clash during their breakthroughs.

  Kai sat cross-legged, surrounded by glowing crystals. He closed his eyes and began channeling mana, guiding it into his core. He didn’t rush. He let the energy flow slowly, steadily, filling the void left by the battle.

  He needed to reach Knight level. Only then would his body fully stabilize.

  Across the room, Umbra lay curled in a nest of mana crystals, breathing deep and even. Her body absorbed the dense mana slowly, filling her core. But she needed more, much more, to evolve into Tier 7.

  That was the threshold. The moment when a Spirit Beast shed its primal instincts and stepped into true sentience. She had already surpassed that mentally, thanks to her soul evolving with the help of the Soulberry, but her body still lagged behind.

  She closed her eyes and began to absorb the inheritance of the Darkwind Shadowpanther. The memories surged into her mind like a flood, silent hunts, shadow leaps, the thrill of the kill. She could recognize herself in the beast's movements.

  Her core pulsed, drawing in mana like a black hole.

  She didn’t know what changes Tier 7 would bring. But she was ready.

  She had to be.

  ***

  Time flowed.

  Slowly, Kai’s body began to heal. His mana channels, once strained and brittle from the battle with the centipede general, pulsed steadily again. His core, dormant and flickering, now spun with renewed strength, fully operational.

  With his foundation restored, Kai began the next phase of his transformation.

  He guided mana through his body, focusing on his internal organs. The path of a body refiner was clear: first the blood, then muscles, bones, organs, and finally the skin and senses. Only when every part of the body had been reforged through mana could one break free from the limits of humanity and earn the title of Knight, a warrior whose body and weapon moved as one, whose strength rivaled beasts.

  Kai had already reformed his blood, bones, and muscles. Now, he turned towards his organs.

  Days passed.

  One by one, his organs absorbed mana, reshaping themselves under pressure. His lungs grew stronger, his liver more efficient, his stomach more resilient. Only one remained: the heart.

  Kai focused.

  His heart was already different, rebuilt through venom forging, hardened by pain. But now, it needed to evolve further.

  He pushed mana into the organ, flooding it with energy. The heart absorbed it like a sponge, pulsing with intensity. Venomous blood mixed with pure mana, and the pressure built. His core spun faster, pushing wave after wave into the heart.

  His heartbeat slowed. Then steadied. Then deepened.

  Each beat sent mana-enhanced blood surging through his body. Even his half-finished crescent moon tattoo responded, absorbing moonlight mana from his core. It glowed faintly, reaching 80% completion.

  Kai exhaled.

  He had done it.

  His insides were fully reforged. Only his skin and senses remained.

  Across the chamber, Umbra stirred.

  She had spent days absorbing the inheritance of the Darkwind Shadowpanther, and the transformation was visible. Her darkfire now carried a smoky, shadowy aura. Her body had darkened, the tiger stripes grew darker and darker until they were almost one with the darkness, her presence more intense, like a void wrapped in fur.

  In her mind, new abilities bloomed.

  Shadow Clones, an evolved form of her shadow merging. She could now create autonomous clones made of pure shadow, capable of scouting, distracting, or attacking prey.

  Her control over shadows had deepened. She could now form spikes of dark mana, launching them from within an enemy’s own shadow. A deadly, invisible strike.

  She felt stronger. Sharper. But not enough.

  She needed more.

  Without hesitation, she turned toward the next inheritance, the Abyssal Thunder Gryphon, and began to absorb it.

  The mana crystals around her pulsed violently as she drew in their energy, her body trembling. The gryphon’s memories surged into her mind, storms, aerial hunts, thunderous dives. Her darkfire began to crackle with hints of dark lightning.

  Kai opened his eyes and watched her from across the room.

  He smiled.

  He was glad he could help his friend grow stronger. The world was cruel, he knew that now more than ever. So, he did everything he could to make sure Umbra would be strong enough to survive it.

  He left her to wrestle with the gryphon’s inheritance and turned inward once more, pushing his body to its absolute limit.

  Mana surged through him, enhancing his senses one by one.

  His hearing sharpened; he could hear the faint hum of the crystals around him, the subtle crackle of Umbra’s darkfire in the distance. His sense of smell grew keener, detecting the lingering scent of roasted meat and the mineral tang of raw mana. Even his taste buds were refined, able to distinguish the elemental traces in the air.

  Then he focused on his eyes.

  He converged mana into them, guiding the energy with precision. The crystals around him flared in response, bathing the room in radiant light. With a flash, his vision shifted.

  A new world opened before him.

  His eyes had merged with his spirit sense.

  He could now see the flow of mana, its shape, its rhythm, its density. He turned toward Umbra and saw her not as a beast, but as a swirling mass of dark, intense flames. Her mana was alive, wild, beautiful.

  And suddenly, he understood.

  This was why the Knights could awaken the aura. With vision like this, it was easy to focus mana into a blade, to shape it, to control it. The flow was no longer invisible; it was tangible.

  He took a deep breath and drew in a massive wave of mana, guiding it into his core. He pushed the pure energy to convert into moonlight, then sent it outward to reforge his skin.

  His body glowed.

  The crescent moon tattoo on his chest pulsed, rising from 90%… to 95%… then shining like a full moon.

  It was complete.

  He had reached the first level of the Silver Eclipse Body.

  The light faded. His old skin cracked and fell away like a shell. Beneath it, a new body emerged, refined, radiant, reborn.

  Like a butterfly from a cocoon.

  Kai had done it.

  He was now a Knight. A true body refiner. A fighter in every sense of the word.

  He continued absorbing mana to stabilize his transformation, but his eyes remained fixed on Umbra.

  She was entering her final phase.

  He could feel it; her core was nearly full, pulsing with power.

  Umbra wrestled with the gryphon’s memories, adapting to its innate skills. She could feel Kai’s transformation echoing through their bond, but she didn’t let it distract her.

  She focused.

  She pushed her core to absorb even more mana from the crystals. Her darkfire enveloped her body, forming a sphere of shadow and flame that floated upward.

  Inside, she united with the gryphon’s inheritance.

  Then, like a puzzle piece snapping into place, the panther’s inheritance fused with it.

  The room darkened.

  Dark mana surged, choking the light from the crystals. Inside the cocoon, Umbra changed.

  Her body grew leaner, more feline. Her hawk features sharpened, her beak darkened into a metallic sheen, her eyes deepened into a piercing blue.

  On her shoulder blades, two feather-like bone structures emerged. Around them, dark mana condensed, forming shadowy wings, not of flesh, but of pure darkness.

  Her mana evolved.

  Her darkfire burned deeper, layered with void-like depth. Shadowy smoke rose from it, and faint bolts of dark lightning crackled within.

  She had kept her essence, darkfire, but now it was enhanced. Heat from fire. Destruction from lightning. Precision from shadow.

  This was her.

  The cocoon absorbed the surrounding darkness, then collapsed inward, merging back into her body.

  Umbra floated in the air, wings spread wide, two massive arcs of dark mana flaring from her back.

  She landed softly.

  The wings folded, retreating into the bone structures on her shoulders.

  She was no longer the same.

  She was now Tier 7, reborn into a high-tier monster.

  Her thoughts were clear. Her instincts sharper. Her soul stronger.

  And one thought burned above all others:

  Revenge.

  She would fight the wolf soon.

  And this time… she would win.
