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

My vision was instantly obscured by the dust and became blurry.

Lu Feng and Jin Yao could only stick to each other and grope for the way ahead relying on each other's feelings and memories.

After the wind and sand gradually subsided, an ancient and mysterious castle appeared before them.

This castle seems to have come out of the long river of history. Its walls are covered with traces of time, solemn and dignified.

It stands there quietly, as if telling stories from the past.

Lu Feng and Jin Yao looked at each other, curiosity and determination flashing in their eyes.

They walked towards the castle resolutely, ready to explore the secrets within.

When Lu Feng and his companions pushed open the heavy city gate, an old smell wafted into their noses, carrying with it the vicissitudes of time.

The interior of the castle was dark and damp, and it was obvious that no one had lived there for a long time.

Faint light filtered in through the windows, illuminating patches of dust.

Lu Feng and Jin Yao stepped into this unfamiliar territory cautiously, their hearts filled with vigilance against the unknown.

Lu Feng and his companions walked slowly along the dark corridor, their footsteps so light that they were almost inaudible.

Unexpected dangers may be hidden in every corner, so they remain vigilant at all times and dare not be careless.

Suddenly, Lu Feng's heart tightened, and he felt a strong and unfamiliar breath coming from deep inside.

This breath carried a sense of oppression, causing his heart to beat faster.

"Shh!" Lu Feng stopped and signaled Jin Yao beside him to keep quiet.

Both of them held their breath and dared not make a sound, for fear of alarming the mysterious power.

They watched the movements around them vigilantly, their eyes scanning every corner.

After a moment, a huge shadow slowly emerged from the darkness.

Lu Feng and Jin Yao widened their eyes and stared at the shadow.

As the distance got closer, they finally saw the true face of this huge creature - it was actually a giant beast of enormous size.

This giant beast is huge, as big as a mountain.

It was covered with a layer of hard scales that sparkled with a cold light.

Each scale is as strong as steel, as if it can withstand any attack.

It has two sharp horns on its head, flashing with cold light, which makes people shudder.

What was even more terrifying was that this guardian beast exuded a suffocating pressure, which made Lu Feng and Jin Yao feel that their bodies had become extremely heavy and they were almost unable to move.

This pressure comes not only from its size and strength, but also from the soul, which makes them feel afraid.

Lu Feng and Jin Yao looked solemn, they knew they had encountered a strong enemy this time.

Lu Feng took a deep breath, calmed his mind, and secretly practiced his skills, trying to resist the pressure.

Lu Feng tightly grasped the Human Emperor Sword in his hand and looked at the giant beast in front of him with a firm gaze.

Jin Yao also bit the tip of her tongue, using the pain to keep herself awake.

She formed seals with her hands and cast a defensive barrier that enveloped herself and Lu Feng.

"Human, how dare you trespass into my retreat and disrupt my practice? You deserve to die!" the beast said in a cold voice.

"We didn't know this was your retreat place, otherwise we wouldn't have come in. How about we leave now?" Lu Feng said.

"Hmph! You have no chance to leave. Since you are here, just die!" the giant beast snorted coldly.

The beast took giant steps toward them, each step causing the ground to shake.

The giant beast opened its bloody mouth and spewed out a stream of blazing flames, rushing straight towards the barrier.

The barrier trembled violently under the impact of the flames, but it still managed to withstand the attack.

Lu Feng seized this rare opportunity and swung the Human Emperor Sword, which was flashing with purple light, in his hand without hesitation, and stabbed it towards the giant beast's leg with lightning speed.

However, what Lu Feng did not expect was that the scales on the giant beast were so hard that the sharp blade of the Human Emperor Sword could only leave a shallow mark on its surface and could not cause any substantial damage.

The giant beast felt the pain in its leg, opened its bloody mouth in anger, and let out a deafening roar.

Its thick and powerful tail swept across like a whip, at such a fast speed that people had no time to react.

Lu Feng was hit by a huge force, and his body flew out involuntarily, hitting the wall behind him heavily, making a dull sound.

A mouthful of blood spurted out of Lu Feng's mouth, staining the front of his shirt red, but he had no time to care about his injuries. He endured the pain and struggled to get up from the ground, his eyes full of determination and indomitable spirit.

Lu Feng knew very well that retreating in the face of a powerful beast would only put himself in a desperate situation.

Lu Feng took a deep breath, gripped the Human Emperor Sword tightly again, and rushed towards the giant beast without hesitation.

Lu Feng's figure flashed like a ghost, and he avoided the fierce pounce of the giant beast with amazing speed.

Lu Feng's figure flipped flexibly in the air, like a nimble flying bird.

Then, Lu Feng swung the sword in his hand like lightning, carrying a sharp sword energy, and slashed fiercely at the back of the giant beast.

However, although the attack was powerful, the beast's skin was extremely tough, leaving only a shallow scar on it.

The giant beast roared in pain, with anger flashing in its eyes.

It became more violent and launched attacks continuously, attacking Lu Feng mercilessly with its sharp claws and pointed fangs.

Each attack contained tremendous power, causing the surrounding air to distort.

Faced with such a fierce attack, Lu Feng gritted his teeth and an indomitable fighting spirit surged in his heart.

Lu Feng used all his strength to display his body skills, as light and agile as a leaf in the wind.

Lu Feng skillfully dodged the giant beast's attacks while looking for opportunities to counterattack.

The battle became more and more intense, and every moment was full of thrills and excitement.

Lu Feng kept thinking and observing. The shell of this giant beast was extremely hard. Even his Human Emperor Sword could only leave shallow scratches on it...

After observing for a long time, Lu Feng's eyes lit up. Lu Feng found that the whole body of this giant beast was covered with a hard shell, but his two eyes could not be covered...

Lu Feng's eyes were as sharp as torches as he stared at the giant beast, secretly calculating its movements and rhythm in his mind.

Just when the giant beast relaxed a little, Lu Feng took decisive action, pushed hard with his feet, and soared into the air like an arrow.

The Human Emperor Sword in his hand flashed with cold light and pierced straight into the guardian beast's huge and ferocious eyes.

The giant beast was keenly aware of Lu Feng's intention, but it was too late to completely dodge.

It flapped its wings desperately, trying to change direction to avoid the fatal blow.

However, Lu Feng's speed was far beyond imagination, and he appeared in front of the giant beast almost in the blink of an eye.

Lu Feng's eyes were firm and resolute, and the Human Emperor Sword, with its fierce momentum, accurately pierced into the giant beast's eyes.
