When Lin Feng appeared again, they had entered the dark castle. There was a cold smell inside the dark castle, and the surrounding black fog was filled. The smell from this place made Lin Feng feel very uncomfortable.

It seems that this dark ancient castle is really very strange. You must serve snacks. Otherwise, what terrible things may happen here.

Lin Feng looked at Bai Ling and asked, "can your sword feel the secret?".

Bai Ling said, "wait a moment, I'll urge you to try!".

Lin Feng and others nodded.

Bai Ling continued to urge the white jade sword. With a large amount of mana pouring into the white jade sword, the white jade sword sent out bursts of violent fluctuations.

But.

The white jade sword really just sent out this fluctuation without any induction. Bai Ling frowned and said, "no, I can't sense the specific position. I don't know if it's a little far away from that place?".

Lin Feng said, "it's possible. Now let's explore the dark ancient castle and see if we can find other opportunities. Pay more attention to your white jade sword. If it's close enough, it's estimated that we can find the secret!".

"Yeah.". Bai Ling nodded.

Then Lin Feng and others began to explore the dark ancient castle.

The dark castle is very huge. The crisscross streets extend to different directions of the castle. Lin Feng and they randomly chose a street and walked towards the castle.

On both sides of the street, there are many houses, houses and so on. Lin Feng and they went to some places to explore, but they didn't find any special places.

Some places were blocked by the prohibition. Lin Feng tried to open the prohibition in some places, but when a gap was opened, Lin Feng resolutely sealed the prohibition again.

Because Lin Feng felt an extremely terrible smell from the gap. The smell made him feel shocked. Lin Feng didn't know what kind of terror existed in it, but it was better not to destroy the prohibition. If the terror really came out, it would be a great trouble for them.

The castle is not only huge, but also divided into many layers.

Lin Feng and his family had been in the first layer of the castle for a long time, but they didn't find anything of great value. They came to the second layer of the castle. In the depths of the second layer of the castle, there was a huge palace. Lin Feng and his family entered the palace. After they came here, Lin Feng and others moved because they found that there were 36 bronze pillars in the castle palace.

On these thirty-six bronze pillars, thirty-six gods and demons are bound respectively.

Some gods and demons have three heads and six arms, some gods and demons have twelve eyes, some gods and demons have two wings on their backs, and so on.

The cultivation of these gods and demons in the past years must be very powerful, but now they all die here.

"This is an extremely evil method of sacrifice.".

After seeing the situation in front of her, Liu xueruo showed a surprised expression.

"Oh? Have you seen similar places?" Lin Feng asked curiously.

Liu xueruo said, "I haven't seen a similar place, but I have seen an introduction on an ancient Taoist Scripture.".

"The arrangement of this bronze column is very special, especially according to the arrangement method of 36 Tiangang directions, and the runes on it are also very special. You can take a closer look. Many runes on it look like the figures of creatures kneeling and sacrificing from a distance.".

Lin Feng and others looked carefully. It was really like what Liu xueruo said.

Those runes are special, like runes, not like runes.

But from a distance, it really looks like the figure of creatures kneeling and offering sacrifices.

That's weird enough.

Liu xueruo continued, "this kind of sacrifice requires the flesh and blood spirit of powerful creatures. When sacrificing, these powerful creatures need to be bound on the column, and then activate the runes on the column. Those runes will devour the flesh and blood spirit of these creatures bit by bit.".

"However, their bodies have not been destroyed. Should their flesh and blood spirit still be there?". Said the poisonous ancestor.

Lin Feng said, "no, his flesh and blood spirit is gone.".

The voice fell. Lin Feng gently pointed at a demon corpse across the void, and a light beam penetrated the demon corpse.

The body of the corpse of God and devil went on in an instant.

Vaguely, it can be seen that there was only a layer of skin left on the demon body, which wrapped the bones inside. As for the flesh and blood, they all disappeared. After seeing this scene, poisonous ancestors and others showed their surprised faces.

This kind of sacrifice is really strange.

"What is the purpose of this sacrificial place?".

Lin Feng asked curiously.

This sacrifice is evil and terrible.

It aroused Lin Feng's suspicion. Doesn't it want to revive something terrible?

If so, is that terrible thing resurrected?

This dark ancient castle itself has an extremely evil smell.

After contacting this evil sacrifice, Lin Feng felt more and more uneasy.

"Come on, go up and have a look!".

Lin Feng said.

He wants to quickly find the secret collection related to Bai Ling's white jade sword. It's best to find the guy of the stone family's Holy Spirit. However, he hasn't sensed the breath of the stone family's Holy Spirit for the time being, and hasn't seen his trace. He doesn't know whether he is on it or left this dark ancient castle?

Lin Feng hopes that the Holy Spirit of the stone family has not left.

Soon Lin Feng and others came to the third floor of the dark castle.

The third floor is also a variety of crisscross streets, which is very complex and covers a huge area.

Many people are not particularly clear about the area of this ancient castle.

So how big is this ancient castle?

Is Lin Feng fast enough?

It can even be described as fast.

But even if Lin Feng wants to fly from one end of the castle to the other, it will take more than a day, and the castle is in a circular distribution.

Therefore, one day is definitely not enough to fully explore the ancient castle. It takes at least four or five days.

When she came to the third ancient castle, the white jade sword mastered by Bai Ling sent out waves. Although this wave is not particularly strong, whether it is strong or not, it is enough as long as there is a wave.

This shows that the white jade sword has an induction to the secret collection.

Everyone looked at Bai Ling.

Bai Ling was whispering something at the moment, as if she were reciting a moving spell.

She should be communicating with Baiyu Xiaojian.

Lin Feng and others did not disturb Bai Ling.

About a quarter of an hour later, the white jade sword rose into the sky and flew quickly to the front.

Lin Feng followed them quickly.

White jade sword goes deep all the way.

One day later, the white jade sword came to the deepest position of the third layer castle. There was also a temple here, but now the gate of the temple was closed.

The white jade sword lingered outside the temple.

"Open the gate of the temple". Lin Feng said.

Poison Zu and others answered and quickly came to the gate.

They worked together to open the gate. The temple was dark and could see nothing.

The darkness here is strange and can even seriously affect the monk's perception.

Lin Feng and they all took out a night pearl, took it in their hands and walked towards the interior of the temple.

Lin Feng found that there were three passages in the temple, leading to different places. They chose the leftmost passage and entered the passage.

However, when Lin Feng and others were walking through the passage, they suddenly heard the sound of thumping behind them, which seemed to be the sound of footsteps.

This surprised Lin Feng and others.

What's the matter with the footsteps coming from behind?

No one else should come in here.

Is there any evil?

"Prison demon saint, you are behind the hall!".

Lin Feng said.

The reason why the big prison demon saint is in the last side is because the big prison demon saint has strong strength. If there is any unknown existence in this place, the big prison demon saint should be able to detect the situation behind the last side.

Can remind you in time.

Lin Feng was at the forefront.

There were many rooms next to the first passage, but Lin Feng didn't open those rooms because he felt that the rooms here were very strange and disturbed him.

Lin Feng asks Bai Ling to try to feel every room with the white jade sword. Lin Feng thinks that if the white jade sword can produce strong resonance and vibration, maybe they will find their destination.

After exploring the first channel, the white jade sword didn't change anything.

Lin Feng and others returned the same way.

When returning, the big prison demon saint was in the front and Lin Feng was in the back.

But when they returned, Lin Feng heard them. Behind them, footsteps came out again.

It's weird.

Lin Feng looked back. It was dark and couldn't see anything.

Lin Feng sacrificed the sky fire. The sky fire blocked the passage behind and dispersed the darkness, but he still didn't find anything.

"Shit, what a evil door!".

Lin Feng cursed in a low voice. He took back the sky fire, and then left the first channel with the people. They entered the second channel and still let Bai Ling use the previous method to find the secret they were looking for.

This time there was no footsteps in the passage.

However, footsteps came out of the temple outside.

Dada dada.

Dada dada.

The footsteps outside are rhythmic.

"Don't worry about the sound outside. Let's explore the temple first.". Lin Feng said.

The crowd nodded.

Everyone quickly withdrew their mind.

Nothing was found in the second passage.

Lin Feng they left the second channel and entered the third channel.

In the third channel, the white jade sword fluctuated violently.

This situation gave Lin Feng and others a sudden boost in spirit.

Bai Ling quickly went to the door of the room. Many runes poured out of the white jade sword in her hand. Those runes were integrated with the door prohibition.

Then Lin Feng and them felt that the prohibition in this room began to dissipate rapidly. Without much meeting, all the prohibitions disappeared.

Lin Feng and others pushed open the door and entered the room. They found that the room was actually a woman's room.

Dressing table, very feminine mosquito net, quilt, bed sheet and so on.

"The secret store referred to by the white jade sword is a woman's boudoir? Is it so strange?". Poison Zu couldn't help muttering.

Lin Feng and others also felt strange, but Lin Feng felt something was wrong.

At this time, a gust of overcast wind blew.

The door closes automatically.

Lin Feng and others were surprised. The poisonous ancestor came to the door and wanted to open the door. However, a terrible force shook out from the door and directly shook the poisonous ancestor out. The poisonous ancestor couldn't help spitting out a mouthful of blood.

Bai Ling quickly grabbed Liu xueruo beside her and stabbed Liu xueruo with a white jade sword in her hand.

"Bai Ling, what are you doing?". Liu xueruo cried in horror. She found that it was too late to escape when Bai Ling came to kill her.

Fortunately, Lin Feng noticed Bai Ling when something was wrong, so Lin Feng came to Liu xueruo in time, grabbed Liu xueruo's jade hand, pulled Liu xueruo away half of her body, and Liu xueruo avoided Bai Ling's sword.

Lin Feng quickly took Liu xueruo back and opened a certain distance with Bai Ling.

Lin Feng and others surrounded Bai Ling.

They feel that things are too strange and brain burning.

Isn't Liu xueruo Bai Ling's good friend?

Why did Bai Ling kill Liu xueruo?

"Bai Ling, why did you kill me?". Liu xueruo also couldn't accept it.

"Damn you!".

Bai Ling's mouth showed a gloomy expression.

Lin Feng frowned slightly. He always felt that something was wrong.
