Only after becoming emperor did he realize he was in a fantasy world of immortal cultivation.

Lin Yuan then arrived at the weapon-refining room with a storage bag full of weapon-refining materials.

He sat cross-legged in front of the refining furnace, closed his eyes and concentrated for a moment to adjust his state to its best.

He then opened his eyes, and with a wave of his hand, the furnace lid was lifted by the pull of spiritual energy.

"go!"

With a thought, the opening of his storage bag shimmered, and the main ingredients, "Star Pattern Iron" and "Ice Soul Stone," were precisely thrown into the blazing furnace under the control of his spiritual power.

After a short while, the star-patterned iron began to turn red and soften, and the star-like patterns on it became even clearer under the high temperature.

The Ice Soul Stone then erupted with intense cold air, and the icy blue mist clashed violently with the crimson heat, producing a hissing sound, causing the entire refining furnace to tremble slightly.

Lin Yuan's expression remained unchanged. His ten fingers flew across his hands, sending out streams of pure spiritual energy. Like the most skillful hands, he carefully adjusted the array inside the furnace, controlling the strength and distribution of the spiritual fire.

This is an extremely mentally and spiritually demanding process.

Fine beads of sweat gradually appeared on Lin Yuan's forehead, but his eyes remained focused as he used his perception technique to firmly lock onto every subtle change inside the furnace.

Inside the furnace, the star-patterned molten iron had transformed into a deep base material, while the essence of the Ice Soul Stone, like countless icy blue threads, was perfectly integrated into it, giving the entire molten iron a unique color that contained an inner icy blue starlight.

"Now is the time!" Lin Yuan sensed that the fusion had reached perfection, and without hesitation, he waved his hand again.

The "Concentrated Jade Marrow" then transformed into a warm white light and entered the molten iron, quickly merging with it, calming any remaining energy disturbances and enhancing the material's inherent affinity.

Immediately afterwards, "ethereal sand" fell like a shower of stars, evenly distributed in the sword liquid, enhancing its spiritual conductivity.

With all the auxiliary materials added, the liquid inside the furnace, shimmering with icy blue starlight, had taken shape and was emitting a chilling spiritual energy fluctuation.

Lin Yuan took a deep breath, knowing that the most crucial moment had arrived—shaping and inscribing the array patterns.

His hands suddenly moved faster, and his spiritual power surged forth. He was no longer simply manipulating flames, but using his own spiritual power as a guide, combined with his perception technique to grasp the energy channels, he began to outline the shape of the flying sword.

Under his spiritual power and subtle adjustments using his perception technique, the liquid slowly stretched and shaped into the prototype of a three-foot-long sword.

The sword's blade flows like waves, its light shimmering and graceful, making it exceptionally beautiful.

Next is the inscription of array patterns.

Lin Yuan forced out strands of spiritual energy from his fingertips, condensing it into needle-like shapes, and carefully outlined them inside the still not fully solidified sword body.

He depicted the internal spiritual network used to amplify the power of water-based spells, accelerate the circulation of spiritual energy, and conceal the fluctuations of magical artifacts.

Lin Yuan was completely focused, pushing his perception technique to its limit. Sweat rolled down his forehead, and his face turned slightly pale.

However, his hand movements were extremely steady as he cast spells, and invisible spiritual energy arrays were perfectly engraved into the core of the sword.

When the last array pattern was completed, the entire sword trembled violently, and all the outward spiritual light, cold energy, and even the starlight flowing inside disappeared instantly, like rivers flowing into the sea.

The sword's color darkened, presenting a deep blue, almost ink-like texture.

"It's done!"

Lin Yuan gave a low shout and unleashed the final nourishing technique.

The power of the spiritual fire instantly turned gentle.

After a long while, the fire in the stove gradually died down.

The furnace lid opened again, and a long sword with a dark blue body and a beautiful design slowly flew out and hovered in front of Lin Yuan. Only when you get very close can you vaguely sense the terrifying power inside, which is like the depths of ten thousand years of mysterious ice.

Lin Yuan reached out and grasped the sword hilt, and with a gentle swing, without using any spiritual power, fine ice crystals naturally condensed in the air where the sword passed.

"The top-grade magic artifact, 'Mystic Ice,' is complete." A satisfied smile appeared on Lin Yuan's pale face.
