How did a bastard like him become an immortal?

A calm voice rang out from Li Muyun's mouth. When the last word was uttered, his terrifying true essence erupted like a volcano that had been suppressed for years. Visible true essence surged and swirled on his body.

Li Muyun's aura also suddenly surged, and the surging true essence he displayed was close to that of the Golden Core realm!

"Half-step Golden Core? Kid, what kind of bizarre secret technique is this?"

Staring intently at Li Muyun, Yang Xi's old face twitched uncontrollably. This sudden change shocked Yang Xi to the point of near-dumbness. He hurriedly withdrew his martial arts and dared not step forward for a moment. The same question kept popping into his mind: How could this be?

Even Li Xianjiu and Hawke, who were fighting in the distance, stopped their battle and looked in Li Muyun's direction. Hawke's pale face showed an uncertain expression, but the shock and astonishment in his eyes could not be hidden.

Li Xianjiu rolled her eyes and pouted. "You little Yunyun, you've got a trump card up your sleeve. I'd better hurry, or I'll be so embarrassed if he takes down Old Man Yang first and I haven't taken down this ugly freak yet."

As she spoke, she took another big gulp of wine from the gourd, her pretty face flushing red. Suddenly, the sword in her hand gleamed brightly, and she shouted, "Celestial Immortal's Drunken Dream Slays Demons!"

Then, a massive sword beam, spanning three zhang (approximately 10 meters) in length, slashed Hawke, causing him to cough up blood and fly dozens of meters backward...

"call!"

Li Muyun exhaled a deep breath, which was a stream of true essence that seemed to be tangible. His cold eyes, burning with white true essence, looked at Yang Xi, instantly making Yang Xi's heart tremble, as if he had fallen into an ice cave.

The next second, as if thunder had exploded, golden energy and electric arcs suddenly appeared. A blurry figure seemed to tear through space, emitting a piercing explosion, and instantly traversed a distance of more than ten meters. Yang Xi only felt a blur before his eyes, and the figure enveloped in golden energy and lightning was already in front of him.

"What kind of speed is that—"

Before Yang Xi could finish speaking in horror, a fist crackling with lightning, crackling with tingling arcs of electricity, slammed out and viciously struck Yang Xi's chest!

In the [Overlord Transformation] state, Li Muyun's meridians were being stimulated by compressed true essence, and his current speed was unmatched even by a Heavenly Profound Grandmaster.

Yang Xi's expression changed drastically. In his haste, he only had time to cross his arms to protect his chest and circulate his true energy for defense.

In the blink of an eye, Li Muyun's thunderous fist struck the point where his arms were crossed.

"boom!"

The moment the fist collided with Yang Xi, another bolt of lightning erupted from Li Muyun's fist and instantly poured into Yang Xi's body.

"Bang! Bang! Bang!"

Yang Xi was forced to retreat repeatedly by the punch, the ground shattering under his feet. He staggered back more than ten steps before barely managing to regain his footing.

Feeling his arms, which were almost numb, Yang Xi swallowed hard, and a trickle of blood spilled from the corner of his mouth.

Li Muyun opened his palm and pointed it at Yang Xi, saying calmly, "Explode."

Yang Xi's face turned deathly pale instantly. His eyes widened as he realized that there was a hidden power of lightning within his body that Li Muyun was detonating. Recalling the lightning that erupted again after that punch, he realized that it wasn't just the external lightning power that had exploded, but also a lightning technique that had silently entered his body.

Yang Xi hurriedly circulated his true energy to envelop the lightning within his body, but before he could absorb and dissipate it, the restless lightning exploded with a bang as Li Muyun's voice rang out!

"puff!"

Spitting out a mouthful of black blood mixed with dark flesh, Yang Xi's gaze was as venomous as a demon's. He, a dignified Grand Martial Master of the Heavenly Profound Realm, had actually been made so pathetic by a Foundation Establishment kid.

"Cough cough! Good lad, no wonder you dared to seek revenge, so you had such a trump card."

Yang Xi coughed up another mouthful of black blood, slowly stood up, his old face becoming even more ferocious. "I, Yang Xi, have been a force to be reckoned with here for twenty years, and this is the first time I've suffered such a great loss. I didn't want to use that move either, but I never expected to be forced to this point by a little brat like you."

A surge of crimson true energy condensed in his right hand, which he then slammed into his chest. His body trembled violently, and he roared through clenched teeth, "Yang Family Secret Technique!"

As crimson true energy was poured in, Yang Xi's muscles began to swell at a visible speed. His originally withered body instantly became much larger, covered with lava-like crimson patterns, and his eyes were blood red.

He grinned maliciously and hissed, "I can only use the tip of this secret technique to increase my physical strength by 30%, but it's enough to deal with you! Hehe!"

Examining Yang Xi's body, Li Muyun's fighting spirit surged, and the true essence within his meridians began to circulate rapidly, bringing him immense power amidst the intense pain.

As their fists collided, Yang Xi's inner energy surged forth. He roared and shot towards Li Muyun, unleashing a punch that erupted with flames and molten lava, blazing intensely hot.

Faced with Yang Xi's attack, Li Muyun directly condensed a golden shield on his left forearm, and with a bang, he withstood Yang Xi's lava fist. The enormous force pushed Li Muyun back three steps, and the floor tiles under his feet were crushed.

Li Muyun was equally unyielding, his other hand erupting with lightning, arcs of electricity crackling, as he slammed it towards Yang Xi. The two exchanged blows, each aiming for vital points, the clash sending golden light and sparks flying.

After half a day of fighting, Yang Xi's lips curled into a sinister smile. Even with the enhancement of the secret technique, Li Muyun was only a half-step Golden Core cultivator. With such brutal blows, Li Muyun couldn't last long. How could the body of an immortal be compared to that of a martial artist?

"Boy, suffer death!"

With renewed confidence, Yang Xi roared with a sinister smile, abandoning his defense and unleashing a flurry of punches like lava erupting from a volcano, forcing Li Muyun to retreat repeatedly.

"Hahaha, kid, hurry up and show me what other tricks you have!"

"As you wish! Ten times the gravity, disperse!"

Li Muyun shouted in a deep voice. With his angry shout, without the suppression of ten times the gravity, the true essence on the surface of his body surged out completely without restraint. His bright white eyes turned into a stream of light, and his whole body disappeared from Yang Xi's sight in an instant.

"Thunder Technique - Palm Thunder!"

"Thunder Magic - Thunder Orb!"

"Thunder Magic - Thunder Spear!"

In the blink of an eye, Li Muyun's figure transformed around Yang Xi three times in succession, like a lightning illusion, releasing three layers of lightning techniques!

"Boom!"

"what!"

A series of lightning bolts exploded on Yang Xi's body, causing him to scream in agony. Even after using a secret technique, his body was covered in wounds, charred and carbonized, and the lightning power was running rampant in his meridians, leaving him unable to move.

Li Muyun clenched his fist, his true essence flowing through his body, all his true essence converging into his hand. In an instant, the sky turned pitch black, with large patches of black clouds gathering above.

He grinned, this was the first time he had combined domineering immortal techniques with lightning magic, staring at Yang Xi with murderous intent, and raised the corners of his mouth:

"Thunder Technique—Three Levels of Heavenly Punishment!"
