Xihan was shocked beyond words. He never expected that his all-out attack would not only fail to harm Meng in the slightest, but would also cause him such a serious injury.

However, Heam was not defeated by this sudden setback.

He took a deep breath, quickly adjusted his mindset, and began to rapidly condense immortal seals with his hands at a speed that was difficult to detect with the naked eye.

As Xihan moved, a black and white celestial seal gradually appeared behind him.

This immortal seal, like a star in the universe, radiates a mysterious and dazzling light.

What's even more astonishing is that this immortal seal is covered with complex and profound Dao patterns, which are like the laws of the universe, containing endless mysteries.

As Xihan continued to condense Dao seals, black and white energy gates sprang up like mushrooms after rain, surrounding him.

Upon seeing the scene before him, Yuan Zhexian couldn't help but raise the corners of his mouth slightly, revealing a strange and enigmatic smile.

He murmured softly, "The power of Yin and Yang, it's quite interesting indeed!"

At that moment, Xihan also stretched out a hand without showing any weakness. The Yin and Yang power that had been surrounding him seemed to be summoned by some kind of force and began to converge towards his palm at an astonishing speed.

In the blink of an eye, these Yin and Yang energies condensed into a Yin-Yang energy ball that shimmered with a mysterious light in Xihan's palm.

Seeing this, Xihan squeezed hard without hesitation and shouted, "Yin Yang Qian Kun!"

As his words fell, an enormous innate Yin-Yang diagram suddenly unfolded like a scroll, hanging high above Meng's head.

The powerful aura emanating from this innate Yin-Yang diagram is truly awe-inspiring.

Immediately afterwards, beams of energy carrying terrifying power poured down from the Innate Yin-Yang Diagram, like a waterfall, directly striking Meng Hong.

This energy was extremely powerful, as if it would completely engulf Meng.

Despite the fierce attack, Meng showed no sign of panic.

With a wave of his hand, an even more terrifying primordial power rapidly condensed in his hand like a surging wave, instantly forming a dazzling golden energy ball.

Masked and as still as water, he hurled the golden energy ball into the void.

With a whoosh, the golden energy ball, like a meteor streaking across the sky, instantly transformed into several golden rays of light, which, like lightning, directly clashed with the energy light descending from the Innate Yin-Yang Diagram.

In the void, several powerful energies collided with each other, producing a deafening roar.

These energies collided with each other at an astonishing speed, like meteors in the universe, releasing an extremely terrifying energy shockwave.

The shockwave spread rapidly in all directions like a raging torrent, instantly leveling everything in its path.

The world outside Taiyuan Heaven was originally peaceful and tranquil, but under the impact of this terrifying energy, it was instantly transformed beyond recognition.

Mountains collapsed, sea levels dried up, the earth cracked open, and the whole world trembled before this powerful force.

The energies that triggered this disaster vanished into the void instantly after the impact.

Hearing witnessed all of this, he remained completely unmoved.

He calmly observed the scene before him, then once again solidified the immortal seal.

He continuously formed hand seals, and next to the original black and white Yin-Yang Immortal Seal, another black and white Immortal Seal appeared.

With a soft shout from Xihan: "Life is boundless, death is indestructible!"

Life and death are unpredictable!

As soon as he finished speaking, the two immortal seals simultaneously emitted dazzling black and white light, which intertwined to form a huge energy vortex.

The two energy vortexes converged rapidly in the air, and in the blink of an eye, they transformed into two enormous and stunningly beautiful women.

The woman's body was as tall as a mountain, her long hair was as black as ink, and she wore a black dress, like a goddess in the night.

Accompanying her was another woman, whose hair was as white as snow and who wore a white dress, like a fairy in the daytime.

The two women looked exactly alike; their beauty was breathtaking.

When they appeared before the crowd, a look of surprise suddenly appeared on Yuan Zhexian's face, as if he was quite taken aback by the appearance of these two women.

Just as Yuan Zhexian was gazing at the scene before him, a memory suddenly flashed through his mind.

That was the duel between Linglong and Tai'a Qingcheng back then.

In that fierce battle, the magic Linglong used was exactly the same as this mysterious energy at this moment!

Moreover, the two women who suddenly appeared bore a striking resemblance to Linglong in both appearance and demeanor.

This series of coincidences deepened Yuan Zhexian's doubts, and he couldn't help but start to think about the connections between them.

Even Tai'a Qingcheng, who was standing to the side, looked puzzled.

Then, just as Yuan Zhexian was deep in thought, the two women suddenly stretched out one hand each, crossed their hands, and formed a black and white seal to suppress the Dao.

Within that seal, black and white light shone intertwined, as if containing endless mysteries.

Then, something shocking happened.

A gigantic, pitch-black beast, its entire body radiating an aura of death and its face contorted in a ferocious grimace, roared as it flew out from the black Dao seal.

At the same time, from another white Dao seal, a giant beast with a peaceful face and boundless life force flew out.

The two colossal beasts constantly shifted their positions in the void, their respective yin and yang energies rushing towards Meng like two powerful torrents.
