142: Quasi-magic weapon "Thunder"

The next day, the sword embryo, which had been sufficiently nurtured, began to be forged.

The fire used was not ordinary fire, but the true essence fire of a Foundation Establishment Cultivator. This fire consumed a large amount of true essence, and if Lin Feng hadn't been in the eye of the Spiritual Spring and within this third-tier Spiritual Vein, he naturally wouldn't have dared to expend so much true essence.

Of course, its use was extremely great. The sword embryo gradually took shape, occasionally emitting a faint sword hum...

Suddenly, above the Immortal Cave, the Heaven and Earth Spiritual Qi rotated slightly, and a low rumble of thunder faintly emanated from within the residence, not from the central thunder field, but carrying an incomparably sharp Sword Intent that seemed to pierce the sky!

"The sword is about to be completed?!"

Inside the Immortal Cave, the liquid being burned by the true fire was violently churning and trembling, its surface constantly shooting out dazzling blue electric light and sharp metal Qi, emitting bursts of clear and melodious sword cries! A powerful suction force emanated from the liquid, frantically devouring the metal-elemental spiritual power and thunder power from the surrounding Heaven and Earth.

Lin Feng did not hesitate. He immediately sat down cross-legged, forming hand seals, and unreservedly injected his pure Overturning Sea Sword Art spiritual power into it. At the same time, he drew a wisp of the unique Heavenly Thunder Qi of Xuanlei Island, carefully guiding it into the sword embryo.

"Condense!"

He let out a low shout, and his Divine Sense power compressed down with unprecedented intensity!

Buzz, buzz, buzz—!

The sword hum grew louder and louder. The liquid suddenly contracted inward, erupting with dazzling blue-gold light that blinded the eyes!

The light lasted for a full stick of incense before slowly receding.

Only a sheathed longsword, about three feet three inches long, was quietly suspended in mid-air. The scabbard was dark blue, like deep-sea profound iron, with naturally formed patterns on its surface, like interwoven water ripples and thunder. The hilt was simple and fit the hand.

Lin Feng took a deep breath and reached out to grasp the hilt.

Clang—!

The longsword came out at hand! The blade was like a clear autumn stream, bright and transparent, yet faintly, blue electric light flowed within the blade, and a cold glint at the edge seemed capable of cutting through sight! At the sword guard, two ancient small characters quietly appeared—startling thunder!

He lightly flicked the blade with his finger.

"Buzz..." A clear and long sword hum resonated, carrying a hint of thunder's dominance and the ocean's depth, lingering endlessly.

The sword embryo was initially formed, and the Natal Flying Sword "startling thunder" was born!

Although it still needed to be continuously nurtured with his mind and thunder in the future to unleash its full power, at this moment, the quality of "startling thunder" already far surpassed that of ordinary top-tier Magical Artifacts, directly approaching the Spiritual Artifact level! Especially its inherent thunder attribute, which perfectly matched Lin Feng's Overturning Sea Sword Art and his Spiritual Root attribute!

Feeling the seamless connection with "startling thunder" and the ease of control, Lin Feng's heart was filled with heroic spirit. With this sword's assistance, his strength would increase by at least thirty percent!

He played with the "startling thunder" sword for a while, unable to put it down, before returning it to his Dantian for nurturing.

In the days that followed, Lin Feng cultivated even more diligently. With the "startling thunder" sword, when he used thunder for Body Tempering, he would sometimes directly insert the sword into the thunder field, allowing the Heavenly Thunder to temper both himself and the Flying Sword simultaneously. The cultivation of the Overturning Sea Sword Art also progressed greatly due to having a carrier, and the power of his sword moves was incomparable to before.

The Yao Beasts attracted by [Gather Beast] became his best targets for testing his sword. The "startling thunder" sword was incomparably sharp, and combined with the Demon Slayer characteristic, it could often easily break through the defenses of Foundation Establishment Stage Yao Beasts, greatly increasing the efficiency of killing and providing more energy feedback.

One day, he had a sudden idea and tried to slightly increase the intensity of the [Gather Beast] fluctuation, continuously injecting more Divine Power.

As a result, what he attracted was no longer a few sporadic Yao Beasts, but a small beast tide! There were twenty to thirty Qi training (Late Stage) sea beasts, seven or eight Foundation Establishment sea beasts, and even an exceptionally large and terrifying Foundation Establishment (Middle Stage) "Thunder Halberd Mad Shark"!

The beast horde frantically charged the simple protective Formation at the edge of the island, causing the light shield to shake violently.

Lin Feng was not surprised but delighted: "They came at just the right time!"

He let out a long roar, holding the "startling thunder" sword, and actively charged into the beast horde!

"Overturning Sea · Raging Waves!"

The sword light transformed into surging blue waves, one after another, instantly tearing apart three Qi Refinement Late Stage sea beasts.

"startling thunder · Pierce!"

The sword tip erupted with a condensed blue lightning bolt, moving at extreme speed, instantly piercing through the head of a Foundation Establishment Ghost-faced Arrowfish.

The Foundation Establishment (Middle Stage) "Thunder Halberd Mad Shark" roared and charged, its bone halberd on its head condensing terrifying lightning.

A flash of excitement flickered in Lin Feng's eyes. The Ming Wang Purgatory Skill operated at full power, and a dark golden aura shot into the sky. He did not dodge or evade, directly throwing a punch!

"Ming Wang's Fury!"

Boom!

The fist and the thunder halberd collided fiercely, lightning scattered, and the mad shark roared in pain, actually being knocked back several feet by the terrifying force!

Lin Feng, not letting up, transformed the "startling thunder" sword into a blue lightning bolt, aiming directly for its vital point!

This battle lasted for a full hour, causing the rocky beach to collapse and the waves to surge. When the last sea beast was slain, Lin Feng was almost exhausted, with several deep, bone-visible wounds on his body, but his eyes shone astonishingly bright.

Vast and boundless life energy surged into his body like a tide, rapidly healing his injuries and replenishing his consumption. He could clearly feel that his cultivation Bottleneck had loosened again, and the Ming Wang Purgatory Skill also showed faint signs of Breakthrough to the next level!

"It seems that occasionally having a big one yields better results!" Lin Feng wiped the blood from the corner of his mouth, looked at the messy battlefield, and smiled. High risk, high reward!

After the fierce beast tide battle, there was a brief rest and precipitation.

Lin Feng sat cross-legged by the Spiritual Spring in the Immortal Cave, absorbing the vast energy that had not yet been fully digested in his body, while reflecting on the day's battle. The Ming Wang Purgatory Skill steadily improved with each surge and calming of his Qi and blood, making solid progress towards the threshold of a Foundation Establishment Late Stage Body Cultivator. The liquid spiritual power in his Dantian also became more abundant and surging, and the "startling thunder" sword, suspended within, trembled slightly, enjoying the nourishment and cleansing of the spiritual power. The electric light inside the sword body seemed even more agile.

Combat was a shortcut to improving strength, but by no means the only one. Lin Feng knew that true strength stemmed from comprehensive accumulation. Therefore, he devoted more of his free time outside of his fixed daily cultivation to miscellaneous studies such as Formations, talismans, and puppets.

The Dao of Formations was the miscellaneous study he invested the most energy in. The Legacy Jade Slip he obtained from the core area of Xuanlei Island, from that Senior "Formation Madman Hermit," contained profound and extensive knowledge, far exceeding his current Realm. Although he had diligently studied it before, he had only barely stepped into the threshold of a second-tier Formation Master, capable of setting up some common defensive, stealth, and spirit-gathering Formations.

Upon his return this time, his Divine Sense had greatly increased due to the Nurturing Spirit Art, reaching the Peak of the Foundation Establishment Late Stage. His perception of Heaven and Earth Spiritual Qi and his ability to deduce complex rune structures had both undergone a qualitative improvement. Re-studying that Jade Slip, many previously obscure and incomprehensible parts, which had seemed like reading a heavenly book, now suddenly became clear.
