90: Slaying Demons

Hearing Gao De's provocation, the Old Snake hissed and flew out.

The black mud swamp churned as if boiling, and foul-smelling mud surged into the sky. A thick, long black shadow, carrying a nauseating stench, suddenly darted out from the depths of the swamp!

It was none other than the Black Water Profound Serpent!

Its body was dozens of zhang long, entirely covered in viscous, jet-black scales. Its snake eyes were scarlet, and its massive mouth opened to reveal fangs shimmering with a sinister blue toxic gleam.

It did not immediately pounce but circled above the swamp, its cold, sinister gaze locked tightly onto Gao De, its scarlet snake tongue flicking in and out as it sensed everything around it.

That Old Snake had been able to occupy this place for many years; it was by no means a mindless creature.

It recognized Gao De's identity—that Purple Lightning Flood Dragon who had recently become famous and was suspected of having a Dragon King background—and it clearly sensed the opponent's Early Third-Rank Realm.

However, it did not underestimate the opponent because of their slightly lower Realm; instead, it became even more vigilant. After carefully scouting the surroundings and confirming there were no other ambushes, a hint of viciousness and greed flashed in its scarlet slit pupils—if it could devour this Flood Dragon with an extraordinary Bloodline, perhaps it could help it pass its Bottleneck!

Gao De saw the Old Snake's caution and sneered inwardly, further firming his resolve to use it to test his weapon.

Facing such a cunning and cautious opponent was perfect for testing the combat effectiveness of his new Magic Treasure and his own ability to react on the spot.

"Hiss!" The Black Water Profound Serpent launched the first attack. It did not pounce to bite; instead, it slammed its giant tail heavily against the swamp!

"Boom!"

Countless streaks of highly toxic, extremely viscous black mud shot toward Gao De like a rain of arrows, covering a vast range and obscuring his vision.

At the same time, it opened its mouth to spew a thick cloud of black poisonous mist. The stench was overpowering, and wherever it passed, even the air emitted "hissing" corrosive sounds. It spread rapidly, intending to erode Gao De's protective spiritual light and Divine Sense.

Gao De did not dodge or evade. With a thought, the purple scale earth-shaking armor on his body shimmered with light. That layer of faint earthy-yellow halo suddenly became solid, forming an invisible force field.

The incoming toxic mud struck the force field; most of it was directly deflected and slid off, while a small portion adhered to it, only to be instantly scorched and purified by the purple electric arcs dancing on the surface of the armor, unable to erode it in the slightest!

As for the spreading poisonous mist, when it approached within three feet of him, it was naturally repelled and annihilated by the extremely yang and rigid Purple Lightning Thunder Aura, unable to get close at all!

"Good armor!" Gao De secretly praised in his heart; this defense certainly did not disappoint him.

He moved!

He unleashed his Lightning Evasion Technique, his figure transforming into a zigzagging streak of Purple Lightning. Ignoring the obstacles of the poisonous mist and the swamp, he instantly closed in on the Black Water Profound Serpent!

The thunder fang formation-breaking halberd in his hand carried a piercing whistle that tore through the air, stabbing directly at the seven-inch mark of the snake's body!

"Clang!"

A loud sound of metal clashing rang out! The Black Water Profound Serpent's scales were indeed exceptionally hard; the war halberd felt tremendous resistance after piercing in only a few inches.

The Profound Serpent felt pain and let out an angry hiss. Its massive body twisted violently, and its thick snake tail swept over like a steel whip, stirring up gusts of foul wind!

Gao De was completely unafraid and swung his war halberd to block.

"Boom! Bang! Clang!"

A fierce close-quarters battle unfolded above the black mud swamp!

Thunder collided with black water, and Purple Lightning intertwined with poisonous mist.

Gao De danced the thunder fang formation-breaking halberd so tightly that not even water could pass through. At times it was like a venomous dragon emerging from its cave, stabbing directly at vital points; at other times, it was like Mount Tai pressing down, cleaving with the force of a mountain.

Every time the Purple Lightning on the halberd blade collided with the snake scales, in addition to bursting with dazzling sparks and roars, a trace of purple electric arc—so subtle it was almost imperceptible—would, like a persistent maggot, silently sneak into the Black Water Profound Serpent's body along the point of impact!

This was precisely Gao De's tactic!

He knew well that this Old Snake had formidable defenses and tenacious vitality. Relying purely on brute force to clash head-on, even if he could win, it might take a long time, and he might even be injured by its dying counterattack or let it escape.

Therefore, he did not pursue a one-hit kill. Instead, he utilized every opportunity of weapon collision to channel his own pure Power of Thunder, using a secret technique called "Thunder Seed Submerged Guidance" from the "Purple Heaven Dragon Transformation Art", bit by bit into the opponent's body.

These hidden thunder forces were extremely weak. Initially, there was almost no feeling, and they would not erupt immediately; instead, they would hide within the opponent's Meridians and Demonic Power, accumulating continuously.

The Black Water Profound Serpent did not pay attention to these subtle feelings of numbness at first, assuming it was just the normal erosion of the opponent's thunder Divine Ability, which it could suppress with its abundant Demonic Power.

It attacked even more crazily, spitting venom, whipping its giant tail, and even attempting to entangle Gao De with its massive body, while the black mud in the swamp constantly transformed into various forms to harass him.

Gao De, relying on the formidable defense of the purple scale earth-shaking armor and the ultimate speed of his Lightning Evasion, maneuvered and dodged amidst the storm-like attacks. Every time he swung the thunder fang formation-breaking halberd, he precisely blocked or counterattacked, while planting more "Thunder Seeds."

The battle lasted for about the time it takes to burn an incense stick. The two sides seemed evenly matched, fighting heartily.

Although Gao De had a slight upper hand, he was unable to deliver a decisive blow to the opponent.

However, the Black Water Profound Serpent gradually began to feel that something was wrong.

It discovered that the circulation of its Demonic Power had begun to become sluggish, as if many invisible "grains of sand" had appeared in its Meridians, and its movements were no longer as fluid as they were at the beginning.

That lurking feeling of numbness was becoming clearer and clearer, even beginning to ache faintly!

A hint of terror finally flashed in its scarlet slit pupils, realizing that beneath the opponent's seemingly ferocious attacks, such an insidious trap was hidden!

"Roar!" It wanted to force out the foreign thunder force within its body, but it found that it couldn't find the source at all. Those subtle thunder forces had already partially merged with its Demonic Power, like a persistent maggot!

"Only realizing it now? Too late!" Gao De sneered. Seeing the opening exposed by the opponent due to the internal disturbance, he suddenly poured a large amount of Demonic Power into the thunder fang formation-breaking halberd!

"Thunder Strike · Detonate!"

With a low shout, it was not an attack, but the triggering of all the "Thunder Seeds" lurking inside the Black Water Profound Serpent!

"Puff! Puff! Puff! Puff!"

In an instant, inside the Black Water Profound Serpent's massive body, it was as if countless tiny bolts of thunder exploded simultaneously! From head to tail, small bumps constantly bulged on its body surface, then burst open, splattering charred blood and shattered internal organs!

"Hiss——!!!"

The Black Water Profound Serpent let out an unprecedented, miserable howl. Its massive body twisted crazily in the air, its Demonic Qi instantly becoming chaotic and running wild. It could no longer maintain flight, falling toward the swamp like a kite with a broken string.

How could Gao De let this opportunity pass?

He used Lightning Evasion again, moving faster than the falling target, and appeared beside the falling snake head. The thunder fang formation-breaking halberd in his hand gathered all his strength, carrying the destructive Purple Lightning, and fiercely stabbed into its scarlet left eye, piercing through the brain!

"Squish!"

The lightning burst out from the other side of the snake head, completely pulverizing its interior!

The Black Water Profound Serpent's struggle came to an abrupt end. Its massive body slammed into the black mud swamp, splashing mud waves into the sky. After twitching a few times, it was silent forever.

Gao De hovered in mid-air, breathing slightly, watching the snake corpse sinking below. Feeling that nearly half of his Demonic Power had been consumed, a look of satisfaction appeared on his face.

The purple scale earth-shaking armor had astonishing defense, allowing him to ignore most attacks.

The thunder fang formation-breaking halberd was incomparably sharp and could perfectly conduct his Power of Thunder.

And the combination of using Magic Treasure and his own Divine Ability tactics allowed him to successfully slay a veteran Demon King who had a higher Realm than himself and held the geographical advantage, at a relatively small cost!

This trip to test his blade had achieved its purpose to Perfection.
