The ruins of Lotus Valley were still smoking when Yuexin finally allowed himself to breathe. He stood among shattered rooftops, the air thick with the scent of ash and blood, his chest still glowing faintly with the energy of the Heavenly Map. His eyes, sharp as molten gold, scanned the horizon.
Beside him, Lian Yue leaned against a crumbling wall, her blades sheathed but ready, a playful smirk tugging at her lips.
"You were impressive back there," she said, voice low but teasing. "Even with Mortal Vein Realm just awakening, you moved like a true cultivator."
Yuexin shook his head, forcing a grim smile. "Impressive? I barely survived. That was instinct, nothing more."
Lady Yuenei stepped forward, her flowing robes brushing the rubble. Her calm presence contrasted sharply with the chaos around them. "Instinct alone will not save you in the Spirit Vein Realm. You need control, understanding, and patience. Power without guidance is a blade that cuts its wielder first."
Yuexin frowned, pressing his hand to the glowing sigils of the Heavenly Map. He could feel it pulsing in rhythm with his heart, guiding him, whispering secrets in a language older than time.
"Then teach me," he said, voice firm. "I have no time for hesitation."
Lady Yuenei led him to a small plateau overlooking the valley. The ground was cracked and jagged, a scar from the recent battle. She drew a circle in the air with her fingers, and silver threads of energy began to form around Yuexin.
"Focus," she instructed. "The map shows you paths, but it does not grant understanding. Mortal Vein Realm requires balance. Qi must flow freely through every vein. You must feel it, guide it, and master it, or your power will destroy you."
Yuexin closed his eyes. At first, he felt only pain—the shards of his veins, broken and raw. Then, slowly, a warmth began to spread, and he could sense the faint rhythm of the Heavenly Map pulsing within him.
"It's like a river," he murmured. "I can feel it flowing, but… it's wild, uncontrolled."
"Good," Lady Yuenei said softly. "Wildness is the beginning of control. Now, focus on one channel at a time. Let your mind guide the flow. Let the map show you the path."
Hours passed—or perhaps days; time had little meaning when cultivation and energy intertwined. Sweat and blood mixed on Yuexin's skin, and yet he pressed on, learning to guide the flow of qi through his veins, to extend his senses, to feel not only the energy within himself but the currents of the world around him.
The quiet was broken by the sudden presence of Lian Yue, who had been silently observing.
"Enough theory," she said, drawing her twin blades. "Time to see if all that energy can actually kill something."
She lunged at him, her speed blinding, blades carving through the air. Yuexin reacted instinctively, letting the Heavenly Map guide his movements. The sigils on his chest flared, creating ghostly afterimages of his form that mirrored his movements, confusing Lian Yue just enough to give him an opening.
"Not bad," she said, spinning away and landing nimbly on a higher ledge. "But you rely too much on that map. It is a tool, not a crutch. Learn to move with your own instincts, or you will die against someone who can read you."
Yuexin wiped sweat from his brow, nodding. "I understand… but the map… it saved my life. It showed me paths I couldn't see."
"Paths, yes," Lady Yuenei said, approaching. "But in the Spirit Vein Realm, you will face opponents who can manipulate energy, sense your every move, and counter instinct itself. You must learn not just to follow the map, but to think beyond it."
As Yuexin trained, a disturbance rippled through the air. The ground beneath the plateau shivered, and two figures emerged from the floating mist above the valley: one male, one female.
The male was Ren Kai, a Celestial Martial Saint in training, his aura sharp and commanding. His eyes gleamed with amusement and a hint of challenge.
"So… the boy with the map is alive," he said, voice cutting like a sword. "I had wondered if he would survive the eclipse. It seems fate favors the bold—or the foolish."
The female beside him, cloaked in dark robes, exuded a dangerous calm. Her gaze swept over Yuexin, analyzing him as a predator would a rabbit. Yuexin's veins flared instinctively, the Heavenly Map pulsing with a warning.
"Do you recognize us?" Ren Kai asked. "You've attracted attention far beyond your clan, boy. The Celestial Martial Realm has heard whispers of the Devourer. And I… will test whether you are worthy."
"I am Yuexin," he said, stance firm. "I will rise beyond all realms. If you are my obstacle, I will destroy you."
Ren Kai smirked. "Brave words. Let's see if you can back them up."
The ground trembled as they charged, and Yuexin felt the first true weight of challenge beyond survival. The Heavenly Map pulsed, illuminating paths in the rubble, showing the weak points in his opponents' stances.
"I can't rely on it alone," he muttered. "I need control… focus…"
The clash was instantaneous. Ren Kai's blade moved faster than Yuexin's eyes could follow, and the map's afterimages only partially mirrored the assault. Yuexin's body moved instinctively, sidestepping, blocking, and striking, but he quickly realized that Mortal Vein powers alone would not suffice.
Lian Yue leaped to his side, spinning her blades with deadly precision. "Follow my lead! Focus on rhythm, not raw power!"
Yuexin adjusted, sensing the flow of combat as if it were a river. His strikes became smoother, more deliberate. Each pulse of the Heavenly Map guided him, but now he integrated instinct with insight.
Ren Kai's smirk faltered. "Hmm… he's learning fast. Not bad, boy. But can you survive the next phase?"
With a swift motion, Ren Kai channeled Celestial Martial energy into the ground. A shockwave erupted, throwing Yuexin off balance. Stones and rubble flew like missiles. Yuexin barely kept his footing, feeling the raw power of higher cultivation realms for the first time.
Lady Yuenei raised her hands, stabilizing him with Spirit Vein energy, whispering, "Remember, control comes from balance, not brute force."
Yuexin clenched his fists, feeling the Heavenly Map pulse violently. Energy surged through his veins like a storm, and for the first time, he truly commanded the map. Silver threads of power shot outward, colliding with Ren Kai's shockwave, neutralizing it, and sending debris scattering.
The battle raged on, a dance of power, skill, and instinct. Yuexin's body moved faster, strikes sharper, defenses stronger. And yet, he could feel the limits of Mortal Vein Realm pressing against him—the ceiling of his potential, the boundaries of what he could endure.
"Spirit Vein Realm… I need it," he thought, eyes blazing. "I will not stop. I will not lose."
The fight paused as Ren Kai and his companion withdrew, observing Yuexin with newfound respect.
"Impressive," Ren Kai said. "You have instinct… and the map. But instinct alone won't save you. You will need guidance, or you will die in the next realm."
Yuexin's body trembled from exertion. Lian Yue landed beside him, panting. "You're reckless, Yuexin. You rely too much on luck and your map. You need discipline."
"I know," Yuexin admitted. "But I cannot waste time. Every second, every opponent… the world moves faster than I can."
Lady Yuenei nodded. "Then we will train. You will awaken Mortal Vein fully, and then step into Spirit Vein Realm. But remember—every step takes a part of you. Friends, blood, your soul… and still, the path ahead is darker than you imagine."
Yuexin clenched his fists. "I will endure it. I will surpass all realms. And I will devour heaven itself."
Above the floating islands of the Celestial Martial Realm, whispers traveled among the elders.
"The boy with the map… Yuexin," one elder murmured. "He has awakened Mortal Vein. His potential is beyond calculation. He may yet surpass even Celestial Martial Saints."
From the Abyssal Realm, a figure cloaked in shadows, Xuan Ji, observed the valley. "So he lives… and he draws the map's guidance. Patience, boy. Soon, the Abyss will test you… and only then will you truly awaken as the Devourer."
Even the Heavenly Emperor, seated atop the throne of stars, sensed the pulse of the map, a golden thread weaving through the layers of existence. "The Devourer awakens… the world trembles, and heaven itself will face judgment."
That night, Yuexin sat atop a cliff overlooking the ruined valley. The red eclipse had faded, leaving only a faint glow in the sky. The map on his chest pulsed softly, a rhythm of destiny and power, guiding him onward.
Lian Yue sat beside him, silent for a moment before speaking. "Do you know what you're getting into, Yuexin? Beyond Spirit Vein, Celestial Martial… the Abyss… even gods will try to stop you."
"I know," he said, staring at the stars. "I am the last of my clan. I have nothing to lose, and everything to gain. I will rise beyond mortal veins, beyond spirit, beyond heaven itself. I will become the Devourer of Heaven."
Lady Yuenei approached, placing a hand on his shoulder. "Then rest, boy. Tomorrow, training begins in earnest. Spirit Vein awaits—and with it, the first real step toward defying the heavens."
Yuexin's eyes glimmered with determination. The path ahead was long, filled with enemies, trials, and loss. Yet for the first time, he felt it: the pulse of destiny beneath his skin, the map guiding his rise, and the fire of defiance in his heart.
"Let the world come," he whispered to the wind. "Let heaven tremble. I am Yuexin… the Devourer of Heaven."
