Lin Yu and the other two hurried to the center of the inner hall and quickly confirmed that the space below was empty.

"Smash the plane, come on, brother."

Zhang Yuanfeng nodded, and stabbed the ground fiercely with the long spear in his hand.

Although the sound was extremely crisp, the stone slabs on the ground did not move at all.

He refused to believe it and stabbed again with all his strength.

Seeing this, Lin Yu looked puzzled and asked, "Brother Dao, are you not using your full strength?"

As he spoke, Lin Yu held the Qianli Sword and shot out a terrifying sword energy.

The surrounding stone slabs could not withstand the strong force and collapsed directly, revealing the ground below.

However, the spot in the center was still not affected at all and stood firmly in its original place.

"Look, Brother Lin, I've already tried my best, but there's no reaction at all."

...

...

Zhang Yuanfeng curled his lips and said helplessly.

With the strength of Lin Yu and Zhang Yuanfeng, they can easily break the energy barrier that has been nourished for thousands of years.

What's more, it is just an ordinary stone slab, how could it be intact?

Seeing that the two of them didn't seem to be joking, Chen Tiandao also drew his sword and stepped forward to chop with all his strength.

Unexpectedly, the moment the tip of the knife touched the stone slab, it broke and created a hole.

Chen Tiandao looked at the flying knife tip in astonishment and regretted his decision.

"What on earth is this thing? It can even break my sword forged with thousand-year-old black iron. This is weird!"

Unexpectedly, as soon as Chen Tiandao finished speaking, the stone slab in the center of the castle's inner hall actually reacted.

After a violent tremor, it shattered with a bang, revealing darkness underneath.

Lin Yu and Zhang Yuanfeng looked at Chen Tiandao together with suspicion on their faces.

"How is it possible? Even the two of us can't break this stone slab. How can you do it?"

Chen Tiandao was stunned. "I don't know. My knife was broken into pieces."

The two of them looked down through the small hole with full of doubts.

It was pitch black, and there was no sense of danger.

But from the echo, I can tell

The biggest difference from the interior of the castle is simply the lack of light.

"Strange, could it be that because you are from Wuji Palace, this thing sensed your presence?"

Lin Yu said casually and didn't take it to heart.

But his casual words gave Chen Tiandao an epiphany.

"Yes! It's because of Wuji Palace. The Grand Elder said that this thousand-year-old black iron is a unique product of Wuji Palace and there is no such material in the entire Lingjing star field."

Zhang Yuanfeng exclaimed when he heard this, "Great, the bond that has lasted for ten thousand years has finally been caught up by you."

Seeing Zhang Yuanfeng's expression change so quickly, Lin Yu smiled indifferently and joked.

"Brother Dao, didn't you just say that not bringing him in was for his own good?"

Realizing that something was wrong, Zhang Yuanfeng smiled awkwardly, took a step forward and jumped down from the cave.

After landing and steadying his body, he waved to Lin Yu and Chen Tiandao above.

"There's no time to lose, so stop talking about these useless things."

Lin Yu and Chen Tiandao rolled their eyes and jumped down together.

After entering the space below, Lin Yu's Thunder Dao was covered with flashing light.

The light it brings is just enough to illuminate the road ahead.

After walking around, they found that the structure here was exactly the same as the interior hall of the ancient castle above.

"Damn it, it's obviously the same thing, why did the Lengshuang tribe build two of them?"

Zhang Yuanfeng complained, and Fengyundao moved towards the center.

Sure enough, the middle was empty again.

"Hurry up Chen Tiandao, it must be the same routine."

In the same way, Chen Tiandao once again sacrificed his knife to open a layer of stone slab.

But they thought it was just normal, and never expected that they would find the same structure all the way down eighteen floors.

Chen Tiandao's originally sharp knife that could cut through iron like mud has now become a short and compact dagger.

Looking at the dagger in his hand, Chen Tiandao cried out in grief.

"Now that I don't even have a rank anymore, how can I still be called Chen Tiandao!"

Although Lin Yu was helpless, he couldn't help wanting to laugh. Fortunately, he didn't show it. He patted Chen Tiandao's shoulder and comforted him.

"It's okay. Your sacrifice is worth it. There will always be some sacrifices on the road to seeking the truth."

Unlike Lin Yu, Zhang Yuanfeng had already been laughing wildly.

He watched Chen Tiandao's sharp knife turn into a dagger, and it was difficult to hold back.

Noticing Chen Tiandao's resentful look, Zhang Yuanfeng coughed lightly and calmed down.

"Look at the bright side. At least the place where we are standing now is different from the structure of the inner hall of the castle."

After hearing this, Lin Yu and Chen Tiandao regained their seriousness.

Zhang Yuanfeng would push the Wind and Cloud Principle to its limit at every level.

After wrapping and testing the entire space, and confirming that the idea is the same as that of the inner hall, Chen Tiandao will be asked to move to the next area.

But this time it was different. There was a muffled sound coming from under the central stone slab, and there was a small hole on the other side, which should be the road leading to another place.

"Eighteenth floor, this doesn't have a good meaning."

Zhang Yuanfeng said inwardly, looking towards the other end with a deep gaze.

Lin Yu didn't believe in ghosts and gods at all. Of course, he didn't believe in those kind of deceitful ghosts.

"What bad implication is there? Maybe it's just the eighteenth floor."

Lin Yu shrugged, walked alone in the front, and used the Thunder Law to light up the road.

After reaching the other end, you will see a small wooden door.

The top was covered with dust, and it was obvious that no one had walked here for many years.

The three of them looked at each other, prepared themselves and kicked away.

The strong light before their eyes was so bright that the few people who were used to darkness could not open their eyes.

After getting used to it, even Lin Yu couldn't help but be amazed.

"No wonder the entire Lengshuang Clan Castle is so empty, it turns out there's a whole new world beneath the eighteenth floor!"

In front of the three people was a space equivalent to the main hall of an ancient castle.

Inside, a wide variety of animal pills were laid out, and various luxurious animal skin decorations almost covered the entire space. In the center, there was a bench like in a main hall.

Zhang Yuanfeng stepped forward and picked up a beast pill to look at it.

“The peak beast pill of the Heavenly Man Realm.”

As he said that, he turned to look at Lin Yu, "All the beast cores that can be seen here are at the peak of the Heavenly Man Realm!"

As far as the eye can see, there are at least hundreds of beast pills.

Each one is of the same grade as those produced from the remains of the Wolf King.

And they are arranged so neatly without any protective measures.

"It seems that the ancestor of the Lengshuang tribe never thought that someone could reach here and display the beast pills like this, which can only mean that there is no place else to put them."

Lin Yu said secretly, observing his surroundings vigilantly.

After a while, Chen Tiandao finally came out of his shock.

He looked at the beast cores, recalled the various rumors that had happened in the Spirit Realm Star Region, and couldn't help but exclaimed.

"No wonder giant creatures are killed here from time to time, but every time we don't know who did it. Today I finally saw it."
