After more than ten years on the mountain, you will become invincible when you come down.

In an instant, countless mysterious runes shot out from his body, like a gorgeous meteor shower, and merged into the surrounding void.

These mysterious runes contain endless energy and mysterious power of laws, and each one shines with dazzling light.

As the runes were integrated, the entire space began to tremble violently, as if it was about to be torn apart.

A powerful energy wave swept out with Lu Feng as the center, and the void was distorted wherever it passed.

When everyone felt this terrifying power, they all showed surprise on their faces and were full of admiration for Lu Feng.

"We will follow the orders of His Majesty the Human Emperor!" Everyone shouted in unison, their voices shaking the sky, as if they were going to tear the world apart.

Their eyes were full of determination and resoluteness, and their faces were filled with enthusiasm and anticipation for the battle.

At this moment, they are no longer individuals working on their own, but a united and closely collaborative whole.

Following the order, everyone quickly dispersed, each doing their own job, and began to set up the formation according to Lu Feng's instructions.

Some people held formation flags in their hands, stepped on the void, shuttled through the void, and laid down mysterious runes; some people carved complex patterns on the ground, and every stroke contained endless mysteries.

Others are responsible for placing various precious materials into the formation to enhance its power.

For a moment, the entire battlefield became extremely lively.

Various kinds of lights flashed continuously, some were like stars, some were like the scorching sun, and some were like thunder, dazzling people.

These lights intertwined with each other and eventually formed an extremely solid line of defense, like a solid wall of steel.

As the Nine Heavens and Ten Earths Demon-Slaying Formation was completed, Lu Feng also breathed a sigh of relief.

Lu Feng stood quietly in the core area of ​​the formation. His eyes were cold and indifferent, as if they could penetrate time and space, looking far away at the dark creatures that were fiercely attacking the formation.

Lu Feng quickly formed seals with his hands and whispered an ancient and mysterious spell, stimulating the power of the formation to the extreme.

As Lu Feng cast the spell, the formation began to emit a dazzling light, like a blazing sun, emitting endless energy and majesty.

This light illuminated the entire world, causing the surrounding dark creatures to feel fear and uneasiness.

Feeling the huge threat posed by the formation, these dark creatures began to frantically attack the Nine Heavens and Ten Earths Demon-Slaying Formation, trying to break this powerful defense system.

They waved their sharp claws, released evil power, and rushed towards the formation desperately.

However, the Nine Heavens and Ten Earths Demon-Slaying Formation was as solid as Mount Tai and indestructible.

No matter how hard the dark creatures attacked, it always remained stable and remained unmoved.

The light of the formation became increasingly intense, forming an indestructible barrier that trapped the dark creatures inside.

Seeing this, Lu Feng was secretly delighted. He knew that the Nine Heavens and Ten Earths Demon-Slaying Formation had successfully blocked these dark creatures.

However, the dark creatures did not give up their attacks. Instead, they attacked even more fiercely.

As the attacks of the dark creatures became more fierce, the Nine Heavens and Ten Earths Demon-Slaying Formation began to tremble violently, as if it would break at any time.

Lu Feng's expression became extremely solemn. He knew very well that if the formation collapsed, the consequences would be disastrous.

So, Lu Feng concentrated his mind and tried his best to activate the formation, hoping to resist the attack of the dark creatures.

With Lu Feng's urging, the light emitted by the formation surged again, as dazzling as a scorching sun.

The runes in the formation seemed to be given life and began to move, forming an indestructible defensive wall.

These runes are intertwined to resist the attacks of dark creatures.

However, at this moment, a mysterious force suddenly emerged from Lu Feng's body and quickly merged into the formation.

This force was so powerful that the originally loose formation was instantly stabilized.

No matter how frantically the dark creatures attacked, they could not shake the formation in the slightest.

Seeing this scene, Lu Feng finally breathed a sigh of relief. Although his face still showed a trace of fatigue that was difficult to conceal, the determination in his eyes became more and more obvious.

Because Lu Feng knew that as long as he persisted, he would be able to overcome the current difficulties.

Everyone became excited as they saw the formation stabilize.

"Lord Human Emperor is so powerful. These dark creatures can't do anything to us, right?"

"Hehe... they are just some dark creatures. Under the leadership of Lord Human Emperor, it will be easy to destroy them!"

"When our support arrives, it will be the time for these dark creatures to perish!"

Although everyone was excited and praising Lu Feng's strength, this did not change Lu Feng's thoughts.

In fact, Lu Feng's expression became even more solemn, as if he was shrouded in a dark cloud.

Because, at this moment, Lu Feng noticed that there was a powerful being among the dark creatures staring at him, with a cunning and sinister look in his eyes.

This existence is different from other dark creatures. The aura it exudes makes people feel fear and uneasiness.

Lu Feng was keenly aware of its gaze, and a sense of vigilance surged in his heart.

Lu Feng realized that this existence might be stronger than any enemy he had encountered before, and it had already noticed its own fatigue and began to secretly accumulate strength in preparation for a fatal blow.

Lu Feng clenched his teeth and tried to stay calm.

Lu Feng knew that this was a critical moment and he must not let the other party succeed.

Lu Feng secretly told himself, "I must persevere and not let this guy take advantage of me no matter what!"

So Lu Feng took a deep breath, concentrated his energy, and prepared to face the upcoming challenge.

Lu Feng's face was solemn, and he kept making hand gestures with his hands. The primordial purple energy in his body surged out like a tide and was continuously injected into the Nine Heavens and Ten Earths Array.

Lu Feng's eyes were firm, and he was determined to hold this line and not let the dark creatures break through the defense.

In this fierce confrontation, time passed by every second.

Every moment was filled with tension and pressure, but Lu Feng always remained calm, concentrating on controlling the formation and resisting the fierce attacks of the dark creatures.

However, at this moment, the powerful existence among the dark creatures finally couldn't hold back anymore.

It may have sensed the threat posed by the formation to the dark creatures, and decided to take action itself, attacking the formation with all its might.

In an instant, the wind and clouds changed color, and the heaven and earth trembled.

Faced with this situation, Lu Feng was shocked, but he quickly regained his composure.
