Then, the Lord of the Underworld's originally gloomy face instantly turned ferocious. His eyes widened, and his face was full of rage, as if he were about to breathe fire.

Back in the day, when he roamed the heavens and earth, his might shaking the world, Yuan Changsheng's ancestor probably hadn't even been born yet! But now, he was being forced into such a humiliating situation by such a greenhorn, a mere upstart. This was an utter disgrace!

Thinking of this, the Lord of the Underworld was furious. Without hesitation, he mobilized the immense spiritual power in his body that was enough to destroy the world, and roared, "Underworld Yellow Springs!" In an instant, an extremely terrifying energy wave burst out from his body and spread wildly in all directions.

In the blink of an eye, Yuan Changsheng found that his environment had undergone a dramatic change. The surrounding scenery suddenly transformed into a strange place filled with mysterious and eerie power. In this area, the air was thick with yin energy, and the sounds of ghosts wailing and wolves howling were incessant, sending chills down one's spine.

However, Yuan Changsheng showed no fear in the face of such a perilous situation. He suddenly unleashed all his strength, roared, and punched forward. As his punch was thrown, a dazzling, enormous golden light burst forth like a blazing sun, carrying unparalleled power as it hurtled straight ahead.

Just as Yuan Changsheng unleashed this golden light, the Lord of the Underworld slightly raised the corners of his mouth and casually uttered two words: "Rewind."

Before the words were even finished, an unbelievable scene unfolded—the originally imposing and unstoppable golden light, as if drawn by some invisible force of time, began to roll back at a speed visible to the naked eye.

Seeing the golden light from his all-out attack vanish inexplicably, Yuan Changsheng's eyes were filled with shock. He stared blankly at everything before him, his heart filled with disbelief and confusion.

At this moment, the Lord of the Underworld sneered and slowly said, "Boy, do you know why those ancient emperors and unorthodox Dao achievers can easily crush a quasi-emperor level nine expert?"

Let me tell you, that's because a quasi-emperor level expert has only comprehended the power of spatial laws.

"But someone like me, who has once ascended the throne, has already comprehended the far more profound and unfathomable power of the laws of time! Today, I will let you witness the might of these laws of time! Although my power of the laws of time is not yet as terrifying as it was at its peak, it is more than enough to deal with you!"

No sooner had the words left his mouth than Yuan Zhexian and the Ninth Ancestor of the Yuan Clan, who were closely watching the light screen in the ancestral land, witnessed the Lord of the Underworld instantly unleash a secret technique.

In an instant, Yuan Changsheng and the Lord of the Underworld vanished without a trace, leaving not even a trace of their presence.

Seeing this, the Ninth Ancestor of the Yuan Clan spoke with a solemn expression: "Your father has now entered the fifth level of the Quasi-Emperor Realm. With the support of the two peerless physiques, the Ancient Sacred Body and the Sun Body, even ordinary ninth-level Quasi-Emperor experts may not be his match. However, if he were to face an Ancient Emperor-level existence, your father would probably have to go through a tough battle and suffer a great deal of hardship."

As expected, Yuan Changsheng, currently in the Netherworld, was in dire straits. In just a short time, his once-intact clothes were completely torn to shreds, his exposed upper body covered in crisscrossing, deep and shallow, gruesome wounds—a truly shocking sight. In contrast, the Lord of the Netherworld remained unharmed, retaining his initial perfect appearance.

At this critical moment, Yuan Changsheng gritted his teeth, rapidly gathering immense Holy Body power in his left hand and simultaneously condensing incomparably scorching solar power in his right.

Immediately afterwards, his aura erupted like a volcanic eruption, and an extremely terrifying spiritual power surged wildly behind him with overwhelming force, gradually condensing into a huge divine seal formed by two mysterious patterns intertwined at the top and bottom.

Yuan Changsheng stared coldly at the Lord of the Underworld before him, and roared, "The Two Elements Supreme Yang Immortal Technique!" With this roar, the divine seal, radiating boundless pressure and carrying earth-shattering energy, slammed fiercely towards the Lord of the Underworld.

"Celestial arts? How is that possible!"

The Lord of the Underworld was filled with astonishment, and he blurted out in disbelief. His eyes widened as he stared intently at Yuan Changsheng before him, his heart churning with turmoil.

Immediately afterward, the Lord of the Underworld swiftly raised his left hand, his eerie fingers moving deftly in a series of hand seals as he chanted incantations. In an instant, a terrifyingly powerful spiritual force surged forth from his body, sweeping directly towards Yuan Changsheng, accompanied by a furious roar: "Time Reversal!"

However, faced with such a terrifying attack, Yuan Changsheng stood firm like an indestructible mountain.

His body continued to function methodically, the Yin-Yang Supreme Immortal Technique poised to be unleashed. Seeing this, the Lord of the Underworld's face grew increasingly grim, and fine beads of sweat even appeared on his forehead.

Because he discovered that his proud power of the Ancient Emperor's Time Law was completely ineffective against the opponent before him.

Seeing the situation spiraling out of control, the Lord of the Underworld knew he could no longer sit idly by and wait for his doom.

Therefore, he made a decisive decision to devote all his strength to strengthening the defenses of the Netherworld. With a wave of his hands, a continuous stream of spiritual energy surged into the ground like a tidal wave, making this already eerie and sinister area even more solid and dangerous.

Just then, Yuan Changsheng finally completed the preparations for the immortal technique.

He seemed to transform into a dazzling sun, radiating boundless brilliance. In an instant, the previously dark and gloomy Netherworld was illuminated, as if day had arrived. The light emanating from Yuan Changsheng's body, like sharp arrows, crashed against the Netherworld Lord's meticulously constructed defensive barrier with overwhelming force.

With a deafening roar, the Netherworld Lord's Netherworld Underworld could no longer withstand the earth-shattering power and instantly crumbled. At the same time, two figures shot out one after the other from the shattered space and reappeared in the sky above the Yuan Clan's territory.

At this time, both Yuan Changsheng and the Lord of the Underworld were seriously injured.

Yuan Changsheng suffered a backlash of spiritual energy due to forcibly unleashing a divine technique beyond his own capacity, while the Lord of the Underworld suffered a similar massive backlash of spiritual energy because the incredibly powerful divine technique shattered his spatial domain.

The two had barely appeared when they both let out a muffled groan, a trickle of crimson blood spilling from the corner of their mouths. The difference was that Yuan Changsheng's blood was a golden color, while the Lord of the Underworld's blood was a vibrant green.
