At the same time, he quickly sat up straight from the back of the blue ox he was riding.

At this moment, both Laozi's piercing gaze and the astonished expression on his face fully revealed the shock and disbelief deep within his heart!

Even the Tongtian Sect Leader standing to the side showed a look of surprise and doubt.

As two of the Three Pure Ones, they were naturally familiar with the renowned Nine Pure Immortal Light.

Therefore, when this celestial light of primordial purity suddenly appeared,

They immediately recognized this supreme divine power that had long since disappeared!

As the second-ranked of the Three Pure Ones, Yuanshi Tianzun had no reason not to recognize the Nine Pure Immortal Light.

When he witnessed this scene, the expression on his face froze instantly!

Immediately following was an expression of utter disbelief!

This...it's actually the Nine Pure Immortal Light!!

Yuanshi Tianzun exclaimed in shock, his voice trembling with disbelief, "How is this possible? Absolutely impossible!"

"How could he possess the Nine Pure Mystic Light, a technique long lost in the Xuanhuang Universe?!"

No matter how unwilling Yuanshi Tianzun was to believe this fact.

However, the facts speak for themselves.

He had to accept reality: if the Nine Pure Immortal Light clashed with his Taiji Talisman, he would be in big trouble!

As expected.

The Tai Chi symbol that was so arrogant just now.

When it suddenly encountered the Taiqing Immortal Light shot out by Gu Xuan, it was as if an extremely hard block of ice had suddenly encountered a raging fire, and it instantly crumbled!

Especially the two five-clawed golden dragons, one yin and one yang, flying up and down, wrapped around this talisman.

The moment they touched the celestial light of the Supreme Purity, they let out a heart-wrenching wail!

Then, these two once fearsome dragons vanished like a burst bubble.

In the blink of an eye, it vanished into nothingness.

At the same time, the entire Tai Chi symbol seemed to have suffered a severe blow and began to crack and pop, emitting a series of crisp cracking sounds.

On the talisman, fine, interwoven cracks, like a spider web, began to appear.

These cracks are spreading and expanding at a speed visible to the naked eye...

Soon, it covered the entire seal.

The next second, the Taiqing Immortal Light flashed again.

The Tai Chi symbol, already riddled with cracks, could no longer withstand such a powerful impact and shattered instantly into countless tiny fragments.

However, only a short while later...

These fragments were then completely reduced to dust in a flash of divine light.

They fluttered and drifted away with the wind...

......

The loss of innate spiritual treasures.

While Yuanshi Tianzun felt a pang of regret, his deep and sharp eyes were fixed on Gu Xuan.

His eyes revealed an undisguised chilling killing intent!

"Where did you learn this Taiqing Xuanguang technique? Who exactly are you?!"

Faced with the questioning of the Primordial Celestial Venerable.

Gu Xuan merely glanced at the supreme Taoist being opposite him, whose lips curled up slightly, revealing a hint of contempt.

"I am your grandfather!"

"Well, old Biden, didn't expect that, did you?"

Upon hearing these words...

The face of the Primordial Celestial Venerable instantly turned extremely gloomy, and he let out a cold snort.

"Hmph, so what if you master this so-called Nine Pure Profound Light? Although this kind of divine power is amazing, it also consumes a huge amount of magical power."

"With your current cultivation level, Gu Xuan, you're probably just putting on a brave face?"

Before he could finish speaking...

Without further hesitation, Yuanshi Tianzun mobilized the ten thousand dou of chaotic energy within his body.

As the chaotic energy flowed rapidly through his meridians, Yuanshi Tianzun slowly extended his right index finger and gently pointed in the direction where Gu Xuan was.

In an instant.

The once peaceful void suddenly began to tremble violently.

A wisp of hazy, chaotic energy shot out from the fingertip of the Primordial Celestial Venerable, swirling and tumbling in the air like a nimble dragon.

In the blink of an eye, this wisp of chaotic energy condensed into a divine rainbow only the thickness of a finger.

Carrying a terrifying, world-destroying force, it hurtled towards Gu Xuan with lightning speed—
