External Soul Bone, Asura Sword Prison

"Ah—!"

Su Mo's face turned pale, and beads of sweat rolled down his forehead. He let out a low cry of pain, his brows tightly furrowed as his body trembled violently.

Though he was shaking all over from the agony, he did not faint or lose control. He merely gritted his teeth and endured the searing pain.

Golden Crocodile Douluo, standing nearby, did not move. Instead, a trace of delight appeared on his face.

Because Su Mo's current state was not the result of losing control while absorbing a Soul Ring.

Golden Crocodile Douluo vaguely guessed what had happened. Su Mo had most likely obtained an enormous stroke of fortune: an External Soul Bone.

External Soul Bones were special existences apart from the six main Soul Bones.

Their chance of appearing was extremely low, less than one in ten thousand.

Every External Soul Bone possessed growth potential and could continuously evolve as a Spirit Master's cultivation increased.

In terms of value, they were in no way inferior to a Hundred Thousand Year Soul Bone.

As a Titled Douluo who had lived for more than a century, Golden Crocodile Douluo had never absorbed an External Soul Bone himself. However, Spirit Hall's records were extensive and plentiful, and naturally included accounts of External Soul Bones. He understood them well.

Su Mo's current condition closely matched those records.

Golden Crocodile Douluo took a deep breath and suppressed his shock, his gaze fixed tightly on Su Mo in case anything unexpected happened.

A moment later, Su Mo suddenly opened his eyes.

At that instant, a crisp crack came from his back.

With a ripping sound, the clothes on his back tore apart instantly, and a pair of black-gold wings suddenly spread from his shoulder blades.

The wingspan stretched more than three meters, and every feather resembled a sharp sword, gleaming with a chilling light.

The Sword Wings suddenly flapped.

Whoosh—

The fallen leaves on the ground were swept up and scattered in every direction.

Su Mo's body abruptly rose from the ground.

It was his first time flying, so he naturally could not control it well.

The Sword Wings flailed wildly behind him, carrying his body through the air as he swayed from side to side like a child learning to walk.

He tried to control his direction, but his body suddenly tilted left, nearly crashing into a huge tree.

He hastily corrected himself, only to pitch toward the right and slam into the canopy, sending countless branches and leaves rustling down.

Su Mo hurriedly adjusted himself and floundered about in the air for quite some time before finally managing to fly steadily.

He hovered in midair and looked down below.

The feeling of looking down from above and soaring freely filled his heart with an indescribable exhilaration.

Not long ago, he had watched Golden Crocodile Douluo streak through the sky and secretly lamented that he lacked the ability to fly.

Yet just like that, he had gained an External Soul Bone that allowed him to fly.

After a while, Su Mo slowly descended back to the ground. His wings gently folded behind him, and his face was filled with joy.

"Hahaha, Xiao Mo, congratulations! I never expected you to obtain an External Soul Bone! Good! Very good!"

Golden Crocodile Douluo strode forward, his laughter echoing through the forest as he raised a hand and patted Su Mo's shoulder.

He examined the Sword Wings behind Su Mo from top to bottom, his eyes full of amazement.

"Right." Golden Crocodile Douluo suddenly remembered something and asked, "Other than flight, what abilities do these wings have?"

Su Mo smiled faintly. "This External Soul Bone is called the Black Gold Sword Wings.

"It can amplify all my attributes by one hundred percent, allowing me to unleash greater strength in battle and gain even higher agility.

"As for its other abilities, Grandpa Golden Crocodile, please watch."

As soon as he finished speaking, the Black Gold Sword Wings behind him suddenly flapped.

Whoosh—!

His figure shot up from the ground, unbelievably fast.

Twenty meters away stood a huge tree, thick enough that one person could barely wrap their arms around it. Its trunk was straight, and its canopy blotted out the sky.

Su Mo's figure instantly appeared beside the huge tree, and his body suddenly spun.

The Black Gold Sword Wings swept across the trunk.

A flash of black light flickered.

The next moment, Su Mo had already returned to the ground, his back facing the huge tree.

Just then, the huge tree behind him slowly began to tilt. Then, with a thunderous crash, it slammed heavily into the ground.

It was clear just how sharp those Sword Wings were.

Just then, another series of fine cracking sounds came from the wings behind Su Mo.

The Black Gold Sword Wings behind him were changing. The feathers that had once been tightly arranged were actually detaching from the wings one by one and floating behind Su Mo.

In the blink of an eye, dense black-gold Sword Feathers appeared behind Su Mo, each one suspended in midair with its pointed tip facing outward.

Su Mo looked toward a rock wall fifty meters away.

With a thought from him.

Whoosh, whoosh, whoosh, whoosh, whoosh...

Countless sharp sounds of air being torn apart suddenly rang out.

The Sword Feathers floating behind Su Mo instantly transformed into streams of black-gold light and shot toward the rock wall.

The Sword Feathers flew as fast as lightning.

In an instant, a dense barrage of impacts sounded from the rock wall.

Dust and shattered stones flew everywhere.

When the dust settled, the surface of the rock wall was densely embedded with black-gold Sword Feathers.

Some had sunk deeply into the rock wall, leaving only half their feathered tails exposed, while others had embedded themselves completely.

The entire rock wall now resembled a giant hedgehog, bristling with black Sword Feathers.

Su Mo moved his mind.

The Sword Feathers embedded in the rock wall trembled slightly, then seemed to answer a summons. They pulled free from the stone, arcing through the air as they flew back behind Su Mo.

They rearranged themselves in the air, fitting together one by one without the slightest gap. In the blink of an eye, they had once again formed the pair of Black Gold Sword Wings.

With a hiss, the entire pair of wings instantly retracted into his body.

The skin on his back was as smooth as before. If not for the two holes in his clothes, there would have been no sign that anything had just burst out from there.

"Grandpa Golden Crocodile, these are the Black Gold Sword Wings' two methods of attack.

"If I use the disassembly attack, I cannot maintain my ability to fly, but the amplification remains."

Golden Crocodile Douluo sighed. "An External Soul Bone truly deserves to be called a heavenly treasure. Xiao Mo, your fortune is truly extraordinary."

Su Mo smiled. "It is all thanks to Grandpa Golden Crocodile for helping me hunt Soul Beasts."

Golden Crocodile Douluo waved his hand. "Whether one obtains an External Soul Bone depends entirely on one's own fortune."

He paused, curiosity flashing in his eyes. "Right, what is your third Soul Skill?"

"After absorbing the third Soul Ring, my Soul Power broke through to level thirty-two.

"As for my third Soul Skill, it is an area attack and control skill. I call it Asura Sword Prison.

"After it is released, it can form an enormous sealing sword formation.

"Inside the sword formation, countless sword energies will continuously attack the enemy from all directions without end.

"Outside the sword formation, a barrier of sword energy will form. Once it takes shape, Spirit Masters of the same rank will find it difficult to break through.

"If I encounter an opponent far stronger than myself, this sword formation can also buy me time to escape."

Golden Crocodile Douluo nodded after listening. "Not bad. Let's go. It's time for us to head back."

The two figures headed toward the outer region.
