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

Suddenly, Lu Feng seemed to realize something, and the Hongmeng purple energy in his body began to circulate on its own.

As the Hongmeng purple energy flowed, Lu Feng's body gradually adapted to the pressure and his mind became clearer.

Lu Feng continued to move forward, and a ruined palace appeared in front of him.

The hall was filled with an air of decay, and the walls were covered with mottled marks.

In the center of the hall, there was a stone coffin. Lu Feng slowly approached the stone coffin. There were exquisite patterns carved on the coffin lid, revealing a mysterious atmosphere.

Just as Lu Feng was about to push open the coffin lid, a low roar suddenly came from his ears.

He turned around alertly and saw a huge monster rushing towards him from the darkness.

Lu Feng quickly dodged to the side, condensed a ball of purple flame in his hand, and attacked the monster.

The monster dodged the attack nimbly, opened its bloody mouth and spewed out a cloud of black smoke.

Lu Feng used the teleportation technique and instantly came behind the monster, then used all his strength to strike the monster's back with a palm.

The monster roared in pain, turned around and pounced on Lu Feng again.

At the critical moment, Lu Feng summoned the emperor's domineering power to protect his body and blocked the monster's attack.

After a fierce battle, Lu Feng discovered that the monster's weakness was its head.

Lu Feng seized the opportunity, flew into the air, and kicked the monster in the head, causing it to fall to the ground seriously injured.

After getting rid of the monster, Lu Feng came to the sarcophagus, pushed open the lid, and found that there was nothing inside.

"What's going on? There's nothing inside?" Lu Feng frowned.

Lu Feng couldn't help feeling disappointed, but he noticed that there seemed to be a line of small words on the bottom of the coffin.

Lu Feng was stunned, and he looked closer, and found that it said: "The soul of Xue Ji is hidden under the abyss."

Lu Feng was startled and had a bad feeling.

"It seems that we need to explore deeper to find Xueji."

Lu Feng decided to move on and look for the entrance to the abyss.

Lu Feng walked carefully along the passage of the palace, being cautious with every step.

This passage is filled with a mysterious and dangerous atmosphere, as if something unexpected may happen at any time.

Sure enough, not long after walking, Lu Feng encountered the first trap.

The ground suddenly sank, forming a huge pit filled with sharp steel spikes.

However, Lu Feng did not panic. He flashed and easily avoided the trap, showing his superb skills.

Then, the walls quickly closed in from both sides, trying to trap Lu Feng in. However, Lu Feng keenly sensed the danger, and he quickly used a strange body movement to pass through the narrow gap like a ghost, and continued to move forward unscathed.

Then, countless arrows shot from the darkness, densely packed like raindrops. Lu Feng waved the weapon in his hand, shooting down the arrows one after another, and at the same time cleverly used the surrounding objects to block them so that he would not be hurt at all.

There were many similar traps and obstacles along the way, but Lu Feng always remained calm and resourceful.

Lu Feng can only continue to use his strength and wisdom to escape danger time and time again.

As he gradually went deeper into the palace, Lu Feng was getting closer and closer to his goal...

Along the way, Lu Feng encountered many traps, all of which he avoided...

Finally, Lu Feng came to a dark abyss.

The abyss is bottomless and filled with a strange atmosphere.

"Could it be that this is the abyss? Xue Ji is in it?" Lu Feng frowned.

This abyss seems to be bottomless, and Lu Feng has no idea what risks he will encounter in it.

But Lu Feng had no choice but to keep moving forward. He had already arrived here, so he couldn't give up halfway, right?

Lu Feng jumped into the abyss without hesitation.

While falling, Lu Feng felt a powerful attraction sucking him tightly.

He struggled hard, but could not escape the powerful attraction.

Suddenly, a bright light flashed before Lu Feng's eyes, and then he lost consciousness.

At the same time, Jian Yi and the others had already returned to their own area, but Lu Feng had not returned yet...

"Where is Lu Feng? Why hasn't he come back today?" the old man asked puzzledly.

"I haven't seen him. He must have been delayed by something. Let's wait and see. Maybe he will be back soon..." Jian Yi said.

"But, it won't be long before someone comes to collect the immortal crystals. The master hasn't come back, and we don't seem to have any immortal crystals to hand over..." said the old man in black robe.

"That's not all. When we find out one person is missing, there will probably be unnecessary trouble. I don't know where Lu Feng has gone and why he hasn't come back yet..." Dao Er said.

The old man frowned, as if he had a bad premonition.

"Lu Feng is always punctual, and his cultivation has not been sealed. His control over time is better than ours. He hasn't come back yet. Could something have happened?" The old man frowned.

"Uh? How about we go look for him? If anything happens, we can help the master..." Xiaolong said.

"Let's forget it. There's not much time left before we come to collect the fairy crystals. We can only wait. Otherwise, it will be even more troublesome if we find out that there are too many people missing. Now only Lu Feng is missing, maybe we can get away with it..." Jian Yi said.

"But if the master doesn't come back, we will be whipped..." Xiaolong said.

"Lu Feng is really something. Whether so many of us will be whipped depends entirely on him, but he still doesn't even know where we are..." Dao Er said dissatisfiedly.

"Okay, Lu Feng must have his reasons, and he may have found some clues and is investigating. We just need to wait here..." the old man decided.

Everyone didn't say anything more and could only wait.

As time passed, until the black-clothed man who came to collect the immortal crystals arrived, Lu Feng still hadn't returned...
