Lu Yuan cautiously walked into the arch.

Behind the door is a huge cave with many stone stalactite partition walls criss-crossing it.

These things separate the huge space, and the giant cave forms an eerie natural labyrinth.

As he pushed the door in, the originally dark cave gradually brightened, and the temperature inside slowly rose.

If you look closely, the floor of the labyrinth is covered with tender green grass and small lilac flowers. Some unknown bee butterflies dance lightly in it.

How can flowers and plants grow in such a place and attract bees and butterflies? Doubts welled up in Lu Yuan's heart.

He carefully pulled out two flowers and plants, sniffed them, and put a little bit into his mouth to chew.

After a few breaths, he was sure that the stuff was free of toxins. Or that it won't poison him.

The spirit realm of the early stage of the third order made his perception ability unprecedentedly powerful.

The atmosphere here is completely different from the caves outside, something must be at work!

Lu Yuan closed his eyes tightly, and the divine consciousness in his mind was released with all his might.

The entire structure of the cavern immediately appeared in his mind.

Because of the improvement of the spiritual realm, the capacity of his mind also expanded. Therefore, all this information can be stored in his brain, so that he can view and analyze the structure at any time.

It turned out that these stalactite partition walls were all condensed together by external forces, and they must have been made by some ancient power with extremely powerful occult arts.

These items also have a variety of rare ores and plant detritus attached to them.

If a person or demon with low cultivation enters, it will be sucked into the partition wall, and then slowly dissolve and become part of the partition wall.

No wonder there was a faint smell of blood in it. I don't know how much flesh this thing devoured!

Because of the strength of his divine sense, the whole picture of this maze was already imprinted in his mind, so he didn't need to run around in it at all.

In this huge cave, many traps are delicately arranged at the corners of the labyrinth.

And these traps are all connected. In other words, after a person falls into the first trap, his body must move, and there is a high chance of hitting the second trap.

Tricks, Lu Yuan doesn't know much about them. He only knew that there was a master named Mozi in ancient times, and he founded the Mohist school. The Mohist technique was unique in the world at that time.

Later, in the Yu Dynasty, there was a craftsman named Gong Qi Yinghao from the Eastern Olympic Country, who was best at making traps and harming countless people. By chance, he learned the Mojia technique, and since then he has improved his level.

As a result, some of the Central Plains monks instead traveled east to learn his skills.

The old thief of that palace only concentrates on studying skills, regardless of whether he is a scholar or a sage, so many evil monks in the Central Plains have also returned from practice.

Looking at this design, it should be the work of Gong Qi's disciples and grandchildren.

Lu Yuan couldn't help but nod and praise the exquisiteness of the design. He kept all these designs in mind.

He didn't know how to use the mechanism, but the Qilin Heart gave him super understanding, allowing him to understand the method of strengthening the original magic circle through the design of the mechanism.

And also comprehended a new formation - chain formation!

This array is extremely concealed, and when an enemy is hit, other enemies within a certain radius will receive collateral damage. The more people, the better.

This move makes up for Lu Yuan's slightly weaker injury ability.

He examined the giant cave in his mind again, his eyebrows furrowed, and the corners of his mouth raised slightly.

Great stuff! It's a pity that it's buried too deep. Lu Yuan sighed lightly.

"What do you see?"

"There's a good jade buried deep underground. The temperature and light here are different from those in the outer hall, which is the function of this jade."

"It's crisscrossed by walls, and it's easy to suck it in, what should we do, master?"

"Easy to do. Listen to me! Greatsword!"

The Silent Demon Sword suddenly became two feet high, and the red demon qi all over his body skyrocketed. Before he could swing it, the sound of wind and thunder could be faintly heard on the blade.

Lu Yuan gestured with a sword finger and swung it forward.

The greatsword immediately slashed at the stone stalactite partition wall.

The walls are made of solid ore

and plants full of aura, which are usually difficult to cut, but under the slash of the giant sword, they are as soft as tofu.

It's completely one-touch collapse!

"Boom Boom Boom !!"

A series of loud noises echoed through the cavern, and smoke and dust filled the cavern.

In a few breaths, the walls were all cut clean and empty.

Of course, those traps, flowers, and plants and things like that turned to dust.

The greatsword was withdrawn, and it was normal again.

Blessed with the demon pill, it is really much stronger.

Silence is a little unaccustomed to its own power. However, he soon realized that this level of destructive power was barely visible compared to the ultimate power he was pursuing.

After the battle in the previous hall, he has been more angry. This time the place will be cleaned, and it will naturally be extremely happy!

He closed his eyes again, ready to lock on to the piece of jade deep underground.

In less than half a moment, the location of the jade stone had been completely determined, just to the right in the middle of the giant cave. Buried five feet deep underground!

The master and servant are in the same heart. After setting the position, Silence turned into a giant sword and stabbed hard at the ground.

"Boom!"

The greatsword spun and stabbed and turned, and it didn't take long for it to reach it.

Lu Yuan looked down, and sure enough, there was a palm-sized piece of blue-green jade lying in the pit.

He sucked the jade into his palm and looked at it carefully.

The jade is turquoise on the outside, and there is a faint golden air flow on the inside.

When you start with jade, you have a warm feeling.

This warmth instantly spreads to the limbs through the palm of the hand, as if drinking a bowl of steaming mutton soup in the winter, feeling extra comfortable and ironing.

Lu Yuan's spirit was lifted, and he also felt full of demonic energy.

Sure enough, it's a good jade!

"This piece of jade can make such a cave grow tender grass, and it can be seen that it has a powerful spirit of transformation. I don't know much about ores and jade, but I can feel its vitality. I'll call it metamorphosis chalcedony."

"Nice name! But master, my sword body has been fused with the five-star Xuanzhu bead, and nothing else can be inlaid with it, so don't look at me." Silence scratched the back of his head and said a little embarrassed.

"I'm going to let Liu Qianqian do it, and she'll punch holes in the equipment. All three of them wore armor, so they had her punch holes in their breastplates. I don't wear armor, so she'll make me a necklace pendant."

"Pretty good, very good. Do you know the effect of this metamorphosis chalcedony?"

"I guess it's to improve our stamina, defense, and recovery. My intuition is like this, so I have to ask the soldier or the refiner exactly how to do it."

After Lu Yuan finished speaking, he cleaned the jade and put it into the ring.

As soon as they finished doing this, the two of them suddenly felt the ground shake, and there was a roar from the ground, and the entire giant cave was shaking.

"Oops! It's an earthquake!" Annihilation immediately turned into a longsword and jumped back into its scabbard.

Lu Yuan understood at this time.

Metamorphosis chalcedony has always been buried underground, able to suppress the leyline qi and maintain the delicate balance within this small world.

Now that the chalcedony has been removed, the earth's qi will soon begin to be chaotic, and the giant cave will almost collapse.

This place is not to stay for long!

Lu Yuan immediately jumped up lightly and flew forward quickly.

After not flying long, he had already left the dangerous place.

Behind him, there was the sound of a constant crash of rocks—the cave had completely collapsed.

He faintly felt that the thousand-year-old stone stalactic was a few layers below the cave.

However, just now, when he flew out of the giant cave and continued to march inside, Lu Yuan suddenly felt a brief dizziness, and there was a brisk sound of wind in his ears.

It occurred to him in an instant—he had been teleported somewhere else by some kind of mechanism.

Thousands of precautions, still not prevented!

Lu Yuan felt a little annoyed in his heart. Sure enough, there can't be the slightest carelessness in this small secret realm.

Otherwise, you will get carried away and you won't know how to die.

Coming to the new cave, Lu Yuan immediately closed his eyes and sensed where he was.

The powerful third-order spirit realm allowed him to quickly know his location.

He was teleported to the second level above.

Fortunately, it was not too outrageous, and it can be said to be a false alarm.

He began to look for an entrance to the first floor.

The second layer on top of this is noticeably drier than the first, and can even be said to be more stuffy.

Fortunately, Lu Yuan was in the middle of the fourth order, and the demand for air was not particularly large.

After comprehending the second layer of "Qilin True Immortal Formula", he learned the supernatural power "Water and Fire are Invulnerable", and he can hold his breath underwater for more than half an hour.

Now, with the improvement of his cultivation, he can hold his breath for almost an hour.

In addition to stalactites, there are also some unknown ores that emit a red and blue shimmer. He didn't know if it was useful or not, but it looked like it was everywhere anyway, and the color was rather peculiar, so he dug up three pieces and put them into the ring.

Because of the strength of his divine sense, all the structures of the second layer of the cave clearly appeared in his mind.

It's like holding a map.

Although there are many forks in the road on this floor, in Lu Yuan's view, it is equivalent to playing the simplest paper game of "finding the exit".

This game can be played by children around the age of three in Dayu Kingdom.

He couldn't laugh or cry: with a map in his mind, is it really a sense of accomplishment to go to a small secret realm like this?

Lu Yuan twisted his shoulders and neck a little boredly, as if he was wandering on the street, and walked towards the staircase that led to the first floor.

Although it was simple, he learned the lesson just now and did not dare to be arrogant. Otherwise, it's not good to waste time by teleporting elsewhere.

After walking for a while, his nose suddenly twitched.

Hey? There is a demonic spirit!

However, it's not exactly demonic.

It seems to have some ...... Corpse gas!

At this moment, Lu Yuan clearly sensed that there was a figure floating towards him behind him.

That's not a "person."

Because her neck was cut open by a sharp object, leaving only a layer of skin, her whole head hung to the right.

A large cut was also made in the stomach, and the intestines were dragged outside.

She tiptoed towards Lu Yuan, obviously to give him a "surprise".

Lu Yuan was a little speechless—he could really see it from behind, and he knew that the female ghost was going to launch a surprise attack on him.

Well, the master will play with you.

Lu Yuan's heart suddenly became playful.

Seeing that the female ghost walked very close to him, and raised her bloody arm to pinch him, Lu Yuan suddenly turned around quickly, also raised his arms, turned his five fingers into claws, and shouted at the female ghost:

"Wow!!

The female ghost really fell for the trick, and she was so frightened that she exclaimed loudly:

"Ah!!h

Then immediately floated backwards.

While floating, he shook his head and scolded:

"Scared the hell out of me! Scared the hell out of me! Hum! Men don't have a good thing!"

Lu Yuan was not happy:

"Hey, I said young lady, what are you doing! You were the one who planned to scare me first, okay?"

The female ghost was very surprised:

"I've been very careful and cautious, and I've used the magic power of 'Concealment', why can you see it too?"

"Please! What kind of supernatural powers do you have? I can really see and hear it. Are you embarrassed to say anything?" Lu Yuan saw that this female ghost was quite interesting, so he deliberately angered her.

The female ghost hung her head, blushed, gently rolled her intestines, and grinned, "Little brother, are you really so powerful? I think you're only at the fourth order."

Lu Yuan simply sat on the stone and talked to her, "Hey, can you respect me? Put the ghost away."

"Oh! I'm sorry......" The female ghost's face turned red, "I...... I'll take it."

After talking about the body one

Akira has become a petite, delicate, lively and cute little girl.

Her eyes were full of spirituality, as if she was born with an affinity for the soul.

"Well, little brother, my name was Huashang when I was alive, ghost master. What about you?"
