He saw that although the spider spirit's brain had been pierced, there were still many intact pearl-like particles in the head.

Lu Yuan took them out.

It's actually a brain spirit bead?!

Such a garbage monster actually has a brain spirit bead?

This thing gathers most of the demonic power of the youkai, and it is very pure, with very few impurities.

Although the demon master can't eat it, the demon attendant can greatly improve his cultivation if he eats it.

Sometimes you can even break through the entrance of the ranks!

There is nowhere to find the iron shoes, and it takes no effort to get it!

Such a big lump is enough for four demon servants to eat. Their cultivation can be improved by several stars.

Hahahaha! As soon as you come here, you will encounter such a rare thing, this trip is a good deal!

Lu Yuan happily put the Brain Spirit Bead into the ring.

After burning the Spider King's corpse with a fire, he instinctively chose a fork in the road and continued on his way.

There is also a road behind the fork in the road, but it is much wider than the one you came in.

The darkness was completely unable to stop the Kirin's true night vision. After walking a few steps, Lu Yuan found that instead of a natural rock wall, he was surrounded by a wall paved with neatly cut stone bricks.

These bricks have gone through countless years, and in some places have begun to break and loosen. But strangely, in such a humid environment, there is no moss growing on the bricks.

Lu Yuan touched it carefully, it was very dry.

Although he had doubts, he didn't think too much about it.

After walking forward for a while, some murals gradually appeared on the brick wall.

It uses the simple pen style of the ancient people to draw scenes of the battles and lives of the human race and the demon race.

Lu Yuan had never seen these things before, he was very curious, and looked at them carefully.

Although the strokes of these murals are simple, the narrative is very clear.

It seems to say that the human race and the demon race were at peace before, and then because of a one-armed man, the two sides fought.

It was at this time that the Yin Demon and the Yang Demon were separated.

The demon clan has a command at this time, and he has a larger body than ordinary demons in the picture, with longer ears and teeth.

Then several tall Terrans joined forces to defeat him and seal the one-armed man.

Lu Yuan is relatively good at ancient history, but he has never read this content.

Kirin Heart has a strong memory, and he memorizes all these images in his mind.

It seems that the history books are not yet fully documented. He smiled and didn't stop walking.

After walking for a while, the corridor suddenly widened, and a medium-sized stone hall appeared in front of it.

The atrium has an arch with a quaint shape on the wall.

The door was about a foot wide, and the whole gave off a faint purple light.

He quickly floated over to check. The arch was attached to a powerful Xuanli prohibition, and the sound of thunder was faintly heard.

Lu Yuan had read some books about "forbidden" before, and knew that this was also a kind of magic circle, but it didn't need a formation flag, and it was much more powerful.

He drew his Sword of Silence and slashed at the Forbidden with all his might.

"Boom!"

There was a loud bang, and the prohibition did not move.

The rocks above the head began to loosen and a few pieces fell.

Another slash, but the ban is still strong.

The sound of the explosion was particularly loud in a narrow area.

But the stones above the head fell more.

Lu Yuan stopped attacking.

If this is cut by brute force, I am afraid that the entire cave will collapse.

Although he has a fourth-order four-star, if a whole mountain is pressed down, he can't bear it.

If you have a lock, you will always have a key!

He searched the side carefully, but found nothing that could lift the ban.

It seems that this road will not work for the time being.

Anyway, there are several intersections, and there is only one straight road back here. It's better to go back to the Spider Hall first, and then choose another route

。

Thinking of this, Lu Yuan walked back.

The way back felt like a little faster. It didn't take long to come to the end of the road.

Lu Yuan walked out of the passage and looked into the hall.

It doesn't matter if you don't look at it, his heart is cold when he sees it.

Where is the spider hall outside the corridor, it is still the middle hall!

The arch still glowed faintly purple at the forefront.

It's weird, there's only one way, why did I come back here?

Hallucination!

He immediately closed his eyes, then opened them suddenly.

A reddish patch appeared in the corner of his outer eye, and the Kirin True Eye carefully scanned every corner.

But no matter how closely he looked at it, he still didn't see any clues.

He summoned the Silent Flying Sword to slash through the hall, marking the cave walls with countless sword marks of different shades, but nothing out of the ordinary happened.

There must be something nearby, but I just didn't notice it!

Lu Yuan simply sat down, ready to meditate and enter the cultivation state.

At this moment, a person suddenly ran at the entrance.

How could there be a second person coming in in such a remote place?

He immediately looked over with alarm.

The person who ran over was actually Liu Qianqian!

"Qianqian! Why are you here?"

"Brother Lu! Call...... ...... exhale," Liu Qianqian breathless, "out of ...... Something is wrong!"

"What's the matter? How did you find this? Why don't you contact me with Tracing Jade?"

"Lu Shan...... Lu Shan was jointly attacked by monsters and human scum and has been lost! They don't know what evil methods have been used to seal our connection with you. I ran out with all my might, and found a Taoist who had searched for you with divination. I...... I flew for a long time and finally ...... Woooooo

Before she finished speaking, Liu Qianqian had already cried until she collapsed, and the whole person collapsed in Lu Yuan's arms.

"What about the two sisters?" Lu Yuan asked anxiously.

"Yes...... I'm sorry! I failed to protect them. They were all ...... Eaten by youkai!"

"What?!"

Lu Yuan's eyes were black, and he almost fainted.

He beat his spirit and hugged Liu Qianqian tightly: "Can you see clearly?"

"Well, it's true, right next to me, I was eaten by two giant youkai!"

The murderous aura on Lu Yuan's body suddenly poured out, and the entire cave was shaky.

"Calm down! The cave looks like it's going to collapse!" Liu Qianqian shouted.

Lu Yuan said in a deep voice, "Go! Revenge!"

"It's too late to fly over now! Before leaving, that Taoist master gave me a teleportation pill, I will crush it and open a portal to Lu Mountain."

"Good. Quick!" Lu Yuan almost roared.

Liu Qianqian took out the blue-black elixir from her bracer and squeezed it hard, and a blue-black portal more than one person tall appeared in front of them.

"Brother Lu, let's go!"

Liu Qianqian pulled him, and the two immediately jumped into the door.

Lu Yuan suddenly felt that there was a great force behind him pulling him.

At this critical juncture, is it a monster?

He looked back, only to see that it was Silence holding him back.

"Master, don't go in, wake up!"

"Annihilation! Are you crazy?"

"Wake up! Master!"

Silence shouted as he punched Lu Yuan his temple.

His eyes darkened, and he came to his senses in an instant.

What is there in front of you? Only a blood-red portal swayed gently in front of him.

"Annihilation, what's going on?" Lu Yuan asked vigilantly.

Silence did not answer him, but continued to shout, "Master, you have a man sitting on your head!"

Lu Yuan immediately brushed his hands towards his head.

He felt the head

There was nothing unusual on it, there was no weight at all, and it was impossible to sit alone.

"Hey, when are you still kidding? What's going on with this portal?"

"The man above your head is dressed in black, his hair hangs down to his waist, his face is pale, his eyes are blood-red, and he almost falls out of his sockets. He has a big blood-red mouth and a long tongue, and it's going to hang down to your face! Don't you see it yet?"

Lu Yuan suddenly realized that where the person described by Silence was a ghost, it was obviously a ghost!

"Master, he's gone!"

Lu Yuan looked up, but still didn't see it.

"He...... He's back! It's lying on your back! Uncle's! Block Lao Tzu's scabbard!"

As soon as Silence finished speaking, he immediately ran behind Lu Yuan to grab the scabbard, and planned to drive the man away.

However, Lu Yuan really didn't notice anything abnormal.

That's right! Silence is a sword spirit, he has yin and yang eyes, and he can see a lot of dirty things!

Is it really a ghost?

Lu Yuan and Silence are in touch. He immediately thought of a way.

"Annihilation! Lend your sight!"

As soon as the words fell, Lu Yuan pointed his sword and wiped it on his eyes.

He immediately gained the vision of the Demon Sword of Silence.

Through the eyes of silence, he saw in his mind that there was indeed a person on his back who did not look like a person, a ghost that did not look like a ghost!

The thing lay on its stomach and stuck a needle-like tongue out of its mouth and stuck it in the back of Lu Yuan's head.

But he didn't feel the slightest pain.

Lu Yuan took a closer look, and only then did he see the situation of this guy clearly-

If you breathe, you can be sure that this guy is not a ghost.

This should be a strange and rare thing between a ghost and a demon - a shadow demon!

It turns out that in a perennially closed environment, if there is a glimmer of light, it will make the things inside produce shadows.

Shadows remain unchanged for thousands of years, and the yin qi in the closed environment is stagnant, and over time, these shadows will give birth to demons, and even open up spiritual intelligence.

What Shadow Demon is best at is influencing people's thinking.

And they are barely visible to the naked eye.

So after many people encounter the shadow demon, they die in their hallucinations in a daze.

Only then did Lu Yuan understand that Liu Qianqian was the illusion produced by the shadow demon using demonic magic to directly affect his brain, and the portal to Lu Mountain was actually a thing that was transmitted to the land of death!

As soon as a person enters it, there is no return, and it will be eaten by countless things like shadow demons.

Lu Yuan was a little scared.

His mid-second-order spirit realm was completely unable to resist higher-order illusion attacks at this time.

Annihilation's innate skill is "Phantom Heart", which is similar to that of this shadow demon.

If it weren't for Silence Seeing Through the Illusion, it would be very likely that Lu Yuan would have confessed here today.

Of course, if it weren't for the fact that Silence had absorbed Xiao Rou's demon pill and his demonic power had been greatly improved, it would have been difficult for him to see this mysterious shadow demon.

"Silence, is there any way you can kill this guy?"

The shadow demon was still lying on Lu Yuan's back, and let out a strange laugh that ordinary people couldn't hear.

He slowly stabbed his spiky tongue deep into Lu Yuan's Heavenly Spirit Cover.
