The Primordial Dao Ancestor had not expected Qin Feng to be able to launch a counterattack. He suddenly shifted his body to the side, narrowly avoiding Qin Feng's attack.

The sword shadows flashed past him like lightning, grazing his clothes and creating a gust of wind.

The Primordial Dao Ancestor's eyes widened in fury, his face contorted with rage. He roared, his voice booming like thunder throughout the space.

His hands thrust forward with the force of a violent storm, and the evil power within the magic circle, like an enraged beast, roared and surged towards the sword shadow like a raging tide.

In the blink of an eye, the surging evil power completely engulfed the sword shadow, instantly devouring it.

However, at that moment, a deep rumble suddenly came from the sky, as if the whole world was trembling.

Qin Feng looked up in astonishment and saw a huge black cloud rushing toward them at an alarming speed.

The dark clouds resembled a moving mountain, obscuring the sky and creating an indescribable sense of oppression.

What's even more unsettling is that eerie light flickers faintly within the dark clouds, as if concealing endless evil and destruction.

Upon seeing this, the Primordial Dao Ancestor revealed a hint of surprise on his face. He laughed wildly, "Hahahaha, brat, you're doomed! This is the Chaos Demon Cloud that I summoned. It will completely devour you, leaving not even ashes behind!"

As the chaotic demonic cloud drew ever closer, space shattered wherever it passed, emitting a series of ear-piercing sounds, as if the entire world were utterly vulnerable before it.

Qin Feng's heart sank, but he felt no fear whatsoever.

He gripped the sword of the Law of Power tightly, and the golden light emanating from his body grew even brighter, like a golden sun, confronting the terrifying chaotic demonic clouds.

"Break!" With a roar from Qin Feng, the power law within his body was instantly activated to its limit.

The sword of the Law of Power shone with dazzling light, like a blazing sun burning in the sky.

Without hesitation, Qin Feng leaped into the air and sped away like a shooting star, his target being the chaotic demonic cloud.

In the blink of an eye, he rushed to Mo Yun like lightning, raising the sword of the Law of Power high and slashing down at Mo Yun with boundless power.

However, the moment the blade made contact with the demonic cloud, there was a loud clang, and the demonic cloud only trembled slightly, without being cleaved.

Moreover, the evil power within the demonic cloud seemed to come alive, rapidly coiling around the sword blade like countless black tentacles, attempting to devour it.

"Boom!" Qin Feng did not back down. He suddenly increased his strength, and the sword of the law of power shone with dazzling light once again.

This time, the demon cloud finally couldn't withstand such powerful force and was forcibly cleaved in a huge crack.

From that crack, evil power surged out like a flood bursting its banks, but it was quickly dispersed by Qin Feng's sword energy.

The Primordial Dao Ancestor, standing at a distance, witnessed this scene, and his face suddenly turned deathly pale.

He clearly hadn't expected Qin Feng to be so powerful, capable of breaking through his Chaos Demon Cloud.

He hurriedly made hand seals, trying to strengthen his control over the demonic cloud, but the demonic cloud had already been severely damaged and could no longer return to its original state.

Seeing this, Qin Feng naturally wouldn't give the Primordial Dao Ancestor any chance to catch his breath.

He pressed his advantage, wielding the sword of the Law of Power like a raging storm, each strike containing terrifying power.

Golden sword energy rained down densely, slamming fiercely into the chaotic demonic clouds.

Under Qin Feng's fierce attacks, the Chaos Demon Cloud trembled continuously, and its evil power gradually dissipated.

Finally, after Qin Feng's last sword strike, the Chaos Demon Cloud completely collapsed, turning into countless fragments that drifted into the void.

Qin Feng, holding the sword of the Law of Force, slowly landed on the ground.

He exuded an unparalleled aura, as if he were the master of this world.

At this moment, the face of the Primordial Dao Ancestor seemed to be shrouded in a thick layer of dark clouds, extremely gloomy.

His once deep and sharp gaze had now become unusually sinister, like that of an enraged beast, staring intently at Qin Feng as if he wanted to devour him alive.

"Boy!" The voice of the Primordial Dao Ancestor was cold and deep, as if it came from the deepest hell, carrying endless chill.

"I never imagined that you, such a tiny ant, could drive me to such a desperate situation!"

His words were filled with anger and resentment, as if he were extremely annoyed by his current situation.

"Now I, the Dao Ancestor, have no choice but to use my trump card, which I specially prepared for breaking through to the Great Dao Realm!"

The Primordial Dao Ancestor gritted his teeth and said, "I originally planned to use it at a crucial moment to ensure that I could break through to the supreme Dao Realm in one fell swoop. But now, because of you, you despicable fellow, I have to use it ahead of schedule!"

By the end, the voice of the Primordial Dao Ancestor was almost a roar. His hatred for Qin Feng grew stronger, and he wished he could tear him to pieces immediately.

Qin Feng remained silent, his eyes fixed on the Primordial Dao Ancestor, as if trying to see through the other's appearance to the depths of his heart.

His expression was unusually solemn, and he gripped the sword of the Law of Force tightly in his hand. The blade shimmered with a faint light, revealing the immense power it contained.

Qin Feng's mind kept flashing back to what Xuan Guang had told him before, about the Primordial Dao Ancestor raising all the beings of the myriad worlds.

He couldn't help but wonder to himself, could the trump card mentioned by the Primordial Dao Ancestor really be related to this matter?

If that's the case, then the Primordial Dao Ancestor might very well have used blood sacrifices to enhance his cultivation level among the beings of all the heavens and myriad realms.

While such cruel methods are appalling, they may not be impossible for someone who pursues the ultimate in power.

Alternatively, the Primordial Dao Ancestor might have had other, even more evil methods, such as using some kind of evil technique to extract the cultivation of all beings in the myriad realms for his own use.

Although this method sounds even more unbelievable, it doesn't seem entirely impossible for the Primordial Dao Ancestor with his strength and methods.

Regardless of what the Primordial Dao Ancestor's trump card is, Qin Feng is certain of one thing: the Primordial Dao Ancestor's cultivation will definitely skyrocket.

Just then, the body of the Primordial Dao Ancestor seemed to be set ablaze, suddenly unleashing an extremely terrifying power of the Heavenly Dao!

This force erupted like a volcanic eruption, instantly surging out and forming a powerful energy shockwave.

As this power erupted, the entire space seemed to be torn apart, producing a deafening roar.

The power of the Heavenly Dao instantly transformed into countless dense threads, which, like lightning, sped off in all directions at an astonishing speed.

Wherever these threads passed, black cracks were torn in the void, as if the entire world was about to be ripped apart by this power.

The silk threads seemed to possess a life of their own, moving nimbly through the void, making it impossible to track their movements.
