Ice and Fire Refine the Golden Body! First Spirit Skill—Poison Dragon's Spiral Jaw!

Deep within the Sunset Forest lies the Ice and Fire Yin-Yang Well.

Red and white spring waters converge in the pool, rising into two distinct mists. The air here is incredibly volatile; ordinary plants cannot survive, and only those Immortal Herbs that have seized the fortune of heaven and earth can compete in splendor.

Yu Tianyu stands by the spring, his upper body bare. His muscles are clearly defined, faintly radiating a fierce aura.

That is the lingering power left behind after absorbing the six-hundred-year Spirit Ring of the Iron-Armored Poison Flood Dragon.

"Hoo..."

He exhales a long breath, his gaze locked onto the two Immortal Herbs at the center of the spring.

On the left is an octagonal plant, snow-white throughout, emitting a heart-stopping chill—the Octagonal Mysterious Ice Grass. On the right, like a fire sprite, is a plant with a red, apricot-like fruit at the top, dancing with flames—the Infernal Delicate Apricot.

"Although my poison resistance is maxed out, the impact of these two extreme attributes still carries some risk."

Yu Tianyu narrows his eyes, a wild and arrogant curve tugging at the corner of his mouth.

"However, if I don't even dare to take this small risk, how can I talk about slaying dragons in a world filled with cheaters?"

The constitution of a Dragon Slayer Mage is born to devour extreme elements!

Without any hesitation.

Yu Tianyu's hands are instantly covered in a layer of dark red dragon scales. He strikes with both hands, not even bothering with jade tools, and pulls the two Immortal Herbs out with his bare hands!

Extreme cold and extreme heat instantly invade through his palms.

His left hand freezes, while his right hand turns charred black.

"Eat!"

He lets out a loud shout, stuffing both Immortal Herbs into his mouth indiscriminately, swallowing them forcibly without even chewing.

"BOOM—!!!"

Two incredibly domineering medicinal forces explode in his stomach, like an ice bomb and a fire bomb detonating simultaneously.

Yu Tianyu's expression changes dramatically in an instant.

One moment, his eyebrows and hair are covered in white frost, as if he were in a ten-thousand-year ice cave; the next second, his skin turns as red as a boiled shrimp, and the sweat that emerges is instantly evaporated into white steam.

Red and blue lights alternate crazily within his body, as if trying to tear his internal organs into pieces.

"Ugh—"

Yu Tianyu lets out a muffled groan, dropping to one knee, gritting his teeth tightly as a trace of blood spills from the corner of his mouth.

Pain!

Pain that goes deep into the bone marrow!

But he does not retreat; instead, he forcibly circulates the Spirit Power within him, guiding this violent energy to wash over his entire body.

"Refine... for me!!!"

While his consciousness is still clear, Yu Tianyu uses his last ounce of strength and leaps—

"Splash!"

He jumps straight into the waters of the Ice and Fire Yin-Yang Well!

As the ice and fire spring water enters his body, the extreme environment of the outside world forms a perfect counter-balance to the medicinal power within.

The violent energy that was about to tear his body apart begins to turn docile under the suppression of the spring water, starting to seep bit by bit into Yu Tianyu's bones, meridians, muscles, and even every single cell.

This is a transformation that sheds his old skin and replaces his bones.

It is not just a strengthening of the flesh, but a baptism for his Dragon Slayer Magic Martial Soul.

Time passes slowly.

The surface of the spring water bubbles and churns, and after a long while, everything returns to calm.

I do not know how much time has passed.

"Splash!"

A sound of water breaks the silence of the valley.

A figure rushes out of the spring water, landing steadily on the rocks by the shore.

It is none other than Yu Tianyu.

At this moment, his appearance has changed drastically.

His previously pale skin has become as warm and tough as jade, faintly glowing with a precious light. Although his physique has not become exaggerated, every muscle seems to contain explosive power.

Most striking are his eyes.

His left eye is as deep as an icy abyss, while his right eye is as scorching as the blazing sun. Deep within his pupils, the original vertical slits have become sharper, as if a true Dragon King is looking down upon the world.

"Is this... the Ice and Fire Golden Body?"

Yu Tianyu clenches his fist, feeling the power surging through his body like a river.

He picks up a sharp rock and drags it hard across his arm.

"Sizzle—"

It actually sparked! It didn't even leave a white mark!

"Impervious to water and fire, immune to all poisons."

Yu Tianyu smiled with satisfaction, "I reckon I could even take a bath in magma from now on without any issues."

Beyond the physical enhancement, he could feel that the Dragon Slayer Magic Power within him had undergone a qualitative change. Although he hadn't directly awakened Ice and Fire Dual Dragon Mode yet, his resistance to fire and ice had been maxed out.

"Since my physical fitness has reached this level, let's try that out..."

Yu Tianyu looked toward a massive granite boulder not far away. It was the stone Dugu Bo usually used to test his moves, incredibly hard.

He slowly lowered his center of gravity and took a deep breath.

First Spirit Ring—that deep yellow six-hundred-year spirit ring slowly rose from beneath his feet.

"Roar—"

A low Dragon Roar resonated within his body.

It wasn't a Fire Dragon's Roar, but a hiss carrying a fishy, cold, and sinister aura.

The resentment and power from that six-hundred-year Iron-Armored Poison Flood Dragon had long been thoroughly tamed by his Dragon Slayer Magic, transformed into his sharpest fangs.

"First Spirit Skill..."

Yu Tianyu's right leg tensed violently.

The spirit power originally covering his body surface instantly converged toward his right leg, and purple-black poison mist erupted, enveloping his entire leg.

The poison mist was not illusory; it condensed into a tangible phantom of dragon scale armor, as if a giant poison dragon's claw were attached to his leg.

Deadly poison!

Power!

Penetration!

"Poison Dragon's—"

Yu Tianyu stomped his foot, and the ground instantly shattered. He shot into the air like an arrow released from a bow, spinning his body mid-air to leverage the strength of his waist and abdomen, whipping his right leg—laden with terrifying toxins—fiercely toward the granite!

"Spiral Jaw!!!"

This was a classic move from Cobra in Fairy Tail, and in this life, it was the strongest single-target attack bestowed upon him by this Poison Flood Dragon.

"BOOM!!!"

A deafening explosion rang out.

That granite boulder, several meters high, was like tofu under Yu Tianyu's foot, shattering instantly!

But it wasn't over yet.

The shattered stones didn't scatter; the moment they touched the force of Yu Tianyu's kick, they were instantly corroded into black powder by that purple-black energy!

Even the flying debris that landed on the ground made "sizzling" corrosive sounds, burning small pits into the earth.

"Hoo..."

Yu Tianyu landed steadily and dispersed the spirit power on his leg.

Looking at the mess before him, the corners of his mouth curled up slightly.

"Not bad."

"The energy of the Poison Dragon Factor is highly concentrated in the leg, not only granting immense physical destructive power but also carrying a violent, corrosive toxin."

"As long as they are hit by this kick, even a defensive-type Soul Elder would have their bones instantly softened, followed by the poison invading their heart."

This was the true value of a six-hundred-year Sub-Dragon spirit ring!

This "Spiral Jaw" perfectly converted the Flood Dragon's naturally powerful tail strength into a leg technique, and combined with the properties of Dragon Slayer Magic, its power far exceeded ordinary century-level spirit skills.

"Now, if I encounter a powerful strength-type Spirit Master, even without using Fire Dragon's Roar, I can play with them using just my physical techniques."

Yu Tianyu flexed his ankle, feeling great.

Just then, the sound of rushing wind approached.

"Tianyu?!"

Dugu Yan's anxious voice rang out at the valley entrance.

Immediately after, a green figure arrived in a flash—it was Dugu Bo.

Today was the weekend, and they had come to pick up Yu Tianyu as promised. They had heard the explosion the moment they reached the entrance and feared something had gone wrong.

However, when they rushed into the valley and saw the shirtless, unscathed boy standing amidst the rubble, the grandfather and granddaughter were both stunned.

At this moment, Yu Tianyu's skin was as clear as jade, and while his aura was restrained, it gave off an extremely dangerous feeling. He was like a young dragon napping, ready to devour anyone at any moment.

"You... you ate those two herbs?!"

Dugu Bo spotted the empty spot in the center of the spring at a glance, his eyes nearly popping out of his head.

Those were highly toxic items that even he didn't dare to touch!

"Eat it."

Yu Tianyu turned around, casually grabbing his clothes and draping them over his shoulders with a look of breezy indifference. "The taste is a bit pungent; remember to prepare some sugar next time."

"..." Dugu Bo opened his mouth, only to find himself completely speechless.

This brat, is he still complaining about the taste?

"Grandfather, look at his aura..." Dugu Yan keenly sensed the difference. "It seems... stronger than it was last week. And his skin..."

Dugu Yan instinctively reached out to touch Yu Tianyu's arm, but he caught her hand in a reverse grip.

"Be careful."

Yu Tianyu looked at her with a faint, mocking smile. "I've just refined the Ice and Fire Power within me. If you touch me recklessly, be careful not to get those pretty hands of yours burned."

Dugu Yan blushed, quickly pulling her hand back and glaring at him coquettishly. "Who... who wanted to touch you! You're full of yourself!"

Dugu Bo watched this scene and shook his head helplessly. He could feel that the Poison Dragon aura within Yu Tianyu had become even more refined, to the point where it even caused his own Jade Phosphorous Serpent Emperor to feel a trace of fear.

"A monster... he really is a monster."

Dugu Bo sighed, yet he also felt a sense of relief. "Since you didn't die, pack up and let's go. The academy has been quite lively these past few days; that little girl named Ye Lingling seems to have been asking about you constantly."

Upon hearing that name, a sharp glint flashed in Yu Tianyu's eyes.

"Ye Lingling, is it..."

"It seems my Second Move is ready to be set in motion."

He straightened his clothes and strode toward the exit of the valley.

The First Spirit Ring was complete, and the Ice and Fire Golden Body had been forged.

Next, it was time to show those so-called geniuses exactly what a true Dimensional Reduction Strike looked like!
