The Unstoppable Wuji

"It's time to test the real power of this system," Wuji muttered, his voice filled with anticipation as he roasted the boar meat he bought earlier. The sizzling of fat dripping into the flames filled the air, and the savory aroma made his stomach growl.

Seated beside a crackling campfire in the forest, Wuji opened the system panel again.

[ System Panel ]

Host: Wuji

Martial Arts Techniques: Iron Shirt (0/16 - Completion)

Energy: 2

Traits: None

"Alright, it's time to discover what this so-called 'trait' is." Wuji rubbed his hands together, a gleam of excitement in his sharp eyes.

Little Red, perched nearby, cocked his head and looked at Wuji strangely. The little crimson ape seemed to be wondering why his boss often spoke to himself.

"Hey, Little Red, this is your piece," Wuji said, tossing a small chunk of roasted boar meat to the tiny ape.

Little Red grabbed the piece and sniffed it but immediately bared his teeth, snatched a much larger chunk, and leapt away with a mischievous grin.

"Alright, you little thief!" Wuji growled, dumbfounded. "I'll roast your monkey ass if you try that again!"

Little Red froze mid-chew, his butt clenching instinctively, before darting into the shadows to enjoy his stolen feast.

With a smirk, Wuji turned his attention back to his meal. CHOMP! He tore into the wild boar meat like a savage, his appetite boundless. The taste was heavenly, but what mattered most was the energy he would gain from the meal.

As he finished, the long-awaited sound of the system echoed in his mind:

[ Ding! Low-Quality Meat Source Digested! ]

[ +40 Energy Points ]

Wuji's eyes lit up as he glanced at the system panel.

'The food digests so quickly… That must be another hidden benefit of this system,' he thought, noticing that his stomach already felt empty despite eating his fill. Yet, strangely, he didn't feel hungry at all.

"Alright, time to get stronger again." Wuji selected the Iron Shirt Technique and pressed the glowing plus symbol. He gritted his teeth, bracing himself for the pain he knew was coming.

[ -16 Energy Points ]

[ Iron Shirt Technique Promoted to True Dao! ]

Suddenly, an excruciating wave of pain coursed through his body. It felt as if his bones were being shattered, stretched, and reforged, while his muscles burned like molten steel was being poured into them.

"Fuck… this really hurts!" Wuji groaned, but a twisted grin formed on his face. "Sooner or later, I'll become a damn masochist at this rate!" Despite the agony, he could feel the overwhelming power surging through his body, pushing him far beyond mortal limits.

As the pain subsided, a deep, almost euphoric comfort spread through him, like the warm embrace of a loved one.

BOOM!

The air around Wuji vibrated violently as his aura erupted like a storm. Suddenly, dark, shadowy tendrils burst from his skin, twisting and writhing around him.

"What the hell?!" Wuji exclaimed, staring in shock as the black tendrils coiled tightly around his body. They fused together, hardening into a layer of flexible, obsidian armor that shimmered with a metallic sheen.

His bulging muscles pushed against the armor, which seemed to mold perfectly to his terrifying physique. Dark tendons pulsed beneath the surface, making him look less like a man and more like a demonic beast. His sharp eyes glowed with an apex predator's ferocity, while a sinister dark iron helm formed on his head, complete with a hoop-like crown that added a majestic, otherworldly aura to his appearance.

[ Iron Shirt Technique Upgraded to True Dao! ]

[ Dark Iron Armor Trait Unlocked! ]

"Holy shit!" Wuji exclaimed, clenching his fists. His powerful hands flexed, causing the armor to ripple like a living organism. "I didn't expect this kind of upgrade. This Dark Iron Armor is insane!"

He examined himself, marveling at the way the armor highlighted his muscles and veins, making him look like a creature of nightmares. "With this, I'm about 2 meters tall. Let's see without the armor..."

Closing his eyes, Wuji willed the armor to retreat. The dark tendrils loosened their grip and slithered back into his skin, leaving him at his natural height of 1.9 meters.

"So, I'm 1.9 meters without the armor," he muttered, flexing his hand as he considered the implications. "Alright, let's test my strength now."

Taking a stance, Wuji punched the air.

BOOM!

The punch echoed like thunder, sending leaves and dust flying in all directions. Wuji's eyes widened in excitement. "That's about 5,000 kilograms of force. Let's see how much stronger I am with the armor on!"

Dark tendrils enveloped him again, forming the sinister armor.

SIUU! BOOM!

This time, the impact of his punch was like a small explosion, shaking the earth and scattering birds from the forest. Villagers in the distance looked around in panic, some thinking it was an earthquake.

"HAHAHA! It triples my power to 15,000 kilograms! That's 15 damn tons!" Wuji roared with laughter, his voice booming like a war drum. The power coursing through his body was intoxicating.

[ True Dao Martial Arts Detected! ]

[ New Function Unlocked ]

'A new function?' Wuji thought, intrigued. "This system keeps getting better. And I discovered another hidden benefit—unlike those garbage systems in novels, this one lets me perfectly control my power right after upgrading!"

Opening the system panel, he read the new update:

[ System Panel ]

Host: Wuji

Martial Arts Techniques: Iron Shirt (0/80 - True Dao) (Unable to Upgrade: Requires Assimilation of Another True Dao Technique)

Energy: 24

Traits: Dark Iron Armor (Triples Power and Enhances Defense)

"Huh, so I can upgrade the technique beyond True Dao? But I need another technique to assimilate," Wuji muttered. "Looks like I'll find what I need at the Night Guard's training ground."

He then noticed the Pet Panel blinking in the corner.

[ Pet Panel ]

No.1 Pet: Little Red (Click to Show Details)

No.2: None

No.3: None

Curious, Wuji clicked on it:

[ Pet Details – Little Red ]

Species: Crimson Abyss Ape (Juvenile)

Can Upgrade To: Mutated Infernal Ape

Loyalty: 100%

"So even Little Red can evolve," Wuji muttered, grinning. "This system really doesn't leave any stone unturned. At least I won't be lonely when I become invincible."

In the distance, Little Red sneezed.

"Alright, it's time to join the Night Guard and register," Wuji said, glancing at the sun hanging brightly in the sky.

"LITTLE RED!" Wuji shouted, his deep voice booming through the forest. The small crimson ape came running, leaping onto his shoulder with a playful screech.

"Don't worry, I'll figure out how to upgrade your bloodline later," Wuji said, ruffling the monkey's head.

Together, Wuji and Little Red set off under the blazing sun, heading toward the Night Guard's training grounds. Despite the bright light, the village seemed perpetually gloomy. But as Wuji walked, his imposing presence seemed to dispel the gloom, leaving awe and fear in his wake.
