The joy on Nanlonghou's face had long gone, and he could only sigh and say:

"It's such a pity that Fellow Daoist Tai failed at the last moment. I wonder if there are other fellow Daoists willing to give it a try?" After saying this, Nanlong Hou deliberately glanced at Wang Tiangu and others.

After all, Wang Tiangu’s reputation as a master of formations is quite well-known in the world of immortal cultivation.

But after the others saw what happened to the woman's treasure being destroyed, their original eager thoughts to try were completely extinguished.

What a joke, there is already a real precedent here. Who would use a treasure to do such a dangerous thing?

Wang Tiangu stood in a corner of the hall, silent.

He knew very well that although he had some understanding of ancient magic arrays, he had never encountered restrictions of the level of the Ten Ancient Forbidden Rules, let alone how to remove them.

In this way, he would not be embarrassed.

But Chen Yun, who had been silent all this time, spoke calmly at this moment.

"I am Chen. I am not very knowledgeable, but I dare to challenge this formation. I would like to ask if the two honorable Taoist friends are willing to support and agree with me?"

Chen Yun expressed his thoughts in a relaxed tone.

However, once this proposal was put forward, it immediately caused shock to Wang Tiangu and the old man surnamed Yun.

As the Marquis of Nanlong, he showed his surprise without any concealment, but he answered without hesitation:
"Of course there is no problem at all. Fellow Daoist Chen, feel free to give it a try!"

Chen Yun did not refuse politely. He immediately took a step forward and walked to the crystal wall that the old woman had failed to conquer before.

Wang Tiangu remained calm, but deep down he did not believe that Chen Yun could break this restriction.

Chen Yun stood in front of the crystal wall and did not take any immediate action. Instead, he raised his right hand, extended a finger, and slightly adjusted the spiritual power in his body. A golden light about several inches long instantly appeared from his fingertips.

As the light flashed, golden light swept across the surface of the crystal wall, but it did not produce any effect, as if the blue jade-like wall was still intact.

However, Chen Yun was not frustrated by this, instead he covered his entire palm with a layer of green spiritual energy. Then, he spread his five fingers apart and pressed his palm against the crystal wall.

Afterwards, he stood completely motionless, as if he was sensing some mysterious power.

Chen Yun's strange behavior confused many monks present, and they all speculated what he wanted to do. However, no one dared to disturb him.

These monks were not aware that Chen Yun, who had his back to them, had a faint blue light flashing deep in his pupils. He stared into the depths of the crystal wall, as if trying to find a way to crack it.

This observation process consumed a full half a quarter of an hour of precious time.

Although no one else showed any impatience on their faces or urged Chen Yun, at this moment, Chen Yun took a deep breath and the blue light in his eyes went out instantly.

Without stopping for a moment, he immediately patted the storage bag on his waist with his left hand, then flipped his palm and took out a large pile of items.

When everyone took a closer look, they were immediately shocked. There were actually more than ten flags of different colors and other magical instruments.

How is this intended to be applied?

"It turns out that Fellow Daoist Chen also has a profound understanding of the art of formations. Could it be that he intends to use formations to break this great divine ban? Have you already understood its mystery?"

After a brief moment of stunned silence, the old man in white shirt asked Chen Yun excitedly.

"It's really not a brilliant move, I just have read some similar ancient magic arrays before. Let's give it a try!"

Chen Yun replied calmly.

As soon as he finished speaking, he opened his mouth and sprayed a stream of golden energy towards the flag in his hand.

A flash of light passed by, and all the formation flags floated up from Chen Yun's hands. Driven by his spiritual power, the tips of the flags pointed directly at the surface of the crystal wall, suspended in mid-air, motionless.

Chen Yun put his hands together in front of his chest and made several marks with a unique technique. More than a dozen formation flags floating in front of the crystal wall fluttered and arranged into complex shapes.

After a few breaths, these flags formed a peculiar and orderly formation, which seemed chaotic but actually contained deep meaning.

However, just as Chen Yun was about to proceed to the next step, he whispered a puzzling spell, and then waved his hands and accurately printed more than a dozen runes on the formation flag.

In an instant, these flags trembled slightly as if they were sensed, emitting colorful light. At the same time, countless tiny rays of light shot out from each flag, interweaving together to form a complex and exquisite magic formation.

Wang Tiangu, Nanlong Hou and other cultivators who are good at formations and who witnessed this scene were all shocked.

Although they felt that the magic circle before them looked familiar, they had never seen the real thing, so they couldn't help but start to speculate about the mystery contained in it.

But Chen Yun did not seem to want others to study the order of this mysterious magic circle too much. He suddenly let out a low roar, and his whole body emanated an extremely dazzling white light.

As they were caught off guard, the other monks present closed their eyes one after another, but they immediately realized that something was wrong and quickly injected spiritual power into their eyes and opened their eyes again.

However, what they saw was a scene that shocked them - the flags and formations on the crystal wall had been perfectly integrated into the crystal wall, as if they were originally a part of the crystal wall.

This discovery surprised Nanlong Hou and the old man in white, and they were full of confidence in Chen Yun's strength!

However, Wang Tiangu, who was also observing the magic circle, had a slightly changed expression, but soon recovered. At this moment, Chen Yun slowly walked towards the crystal wall, covered its surface with both hands, and a pale golden light instantly bloomed.

At the same time, the magic circle in the crystal wall also emitted brilliant five-colored light, gradually covering the entire crystal wall, and the scenery was extremely spectacular.

The eyes of everyone present were attracted by this visual feast, and at this moment, Chen Yun gently moved his right hand away from the crystal wall, and his figure flashed a few times and he was standing in front of the crystal wall on the other side.

After watching for a while, he took out another set of formation flags and set up a magic formation exactly the same as before.

Similarly, a strong white light emanated from his body again, instantly integrating the newly arranged magic circle into the crystal wall.

Because they were prepared this time, although the strong light was still dazzling, Nanlong Hou and others, under the protection of spiritual power, could still clearly see the whole process of Chen Yun controlling the formation flag to enter the crystal wall.

They were all amazed that Chen Yun could break the crystal wall so easily.

Chen Yun used this method to complete the arrangement on four crystal walls. Although it took a lot of time, the other cultivators present did not show any anxiety.

They all understood that it would take a long time to lift such a profound and mysterious ancient restriction.

Of course, this is also due to Chen Yun’s calm response, which gave everyone great confidence.

Otherwise, Nanlong Hou and the old man in white shirt might not be able to endure such a long wait.

The rhythm changed from the initial complexity to an orderly one. The rays of light in the entire space seemed to be connected by telepathy, shining brightly in sync, and at the same time shrinking rapidly, forming an extremely harmonious and unified scene.

Chen Yun did not pay too much attention to the changes in the surrounding glow. He just lowered his head slightly and whispered the word "broken".

As the word fell, the rays of light suddenly burst into an intense light and emitted an unbearable sharp buzzing sound, which gradually intensified and became as spectacular as the singing of hundreds of birds.

Immediately afterwards, a deafening roar was heard, the rosy glow disappeared in an instant, and the entire hall was plunged into endless darkness.

Nanlong Hou and others only noticed at this moment that the crystal wall that originally surrounded them had disappeared silently, and was replaced by an ordinary bluestone wall.

On one of the stone walls, there is a huge stone door that is 70 to 80 feet high and 30 to 40 feet wide.

"It turns out that Fellow Daoist Chen has such a profound research on the art of formations that he has successfully broken this restriction. Haha! Very good, Fellow Daoist Yun and I will naturally keep our promise. After the two of us have selected a treasure, Fellow Daoist can choose the one you like first."

Nanlonghou showed a look of joy in his eyes and said these words with great interest.

When the old man in white saw the stone door, his face was also filled with a joyful smile and his eyes were full of ardent anticipation.

"Brother Nanlong, let's first check what kind of treasures are hidden inside! Are there other restrictions here?" The cultivator named You asked with enthusiasm but still a little concern.

"Please rest assured, there are no other restrictions here. According to the last words left by Master Cangkun, this cave only has two restrictions in total."

Nanlong Hou replied confidently.

After saying this, he took a step forward without hesitation, waved his sleeves lightly, and slowly pushed the stone door open.

Seeing this scene, the last bit of doubt in the hearts of the many monks present disappeared, and they followed closely and stepped into the gate.

"What on earth is this?"

When the old woman saw the scene behind the stone gate clearly, she couldn't help but exclaim.

Not only her, but Chen Yun and everyone else also looked surprised.

Behind the door was a spacious hall that was several times larger than the previous one, but in the center of the hall a small and unique attic suddenly appeared.

This attic is carefully carved from crystal clear white jade. It is over ten feet high and has only two floors, but its level of refinement is unparalleled.

What is even more eye-catching is that above the main entrance of the attic, which is several meters high, three large silver characters "Yuji Pavilion" are engraved, shining brightly.

However, building an attic in such a wide hall always feels quite weird.

In front of the "Yuji Pavilion", there was an old black and yellowed altar, on which was placed a silver-white scroll several feet long, shining with silver light, which was obviously no ordinary item.

Apart from this, the rest of the hall was empty, and no other traces of doorways were found.

"Could it be that the treasure is hidden in this attic?"

Such thoughts involuntarily emerged in the minds of every monk.

Nanlong Hou and the old man in white shirt looked at each other, but in the end Nanlong Hou chose to stay where he was, while the old man stepped forward cautiously and went straight to the altar in front of him.

The old woman and Wang Tiangu and others felt a slight tremor in their hearts, but no one dared to speak out to stop him. They just watched coldly what the old man was doing next.

The old man surnamed Yun did not immediately reach out to take the scroll. Instead, after a slight hesitation, a stream of white light spurted out of his mouth. This bright light directly wrapped the scroll and flew into the air.

After rolling for a while, accompanied by a crisp "swish" sound, the scroll was opened, revealing an image of the back of an elegant scholar with a long sword on his shoulder and looking up at the sky.

"Is this Master Cangkun?" The stern-faced monk stared at the embroidered image and said with a little surprise.

"Perhaps. But the fact that this painting is displayed here must have some meaning. It just may not be a rare item."

Wang Tiangu's eyes moved as he carefully observed Yuge, and he spoke meaningfully.

"Please allow me to try it out and then make a conclusion based on this!"

The old man surnamed Yun thought for a long time and then spoke slowly.

Then he quickly made hand gestures with both hands, and when he flicked his fingers, several red magic spells shot towards the portrait like lightning.

As red light suddenly bloomed on the surface of the portrait, it only lasted for a short moment before quickly returning to its original appearance without any unusual changes.

"It is indeed a little strange! But we cannot rule out the possibility that this is just an ordinary embroidery picture!"

Seeing this scene, the old man surnamed Yun said with a puzzled look on his face.

"In that case, let's keep this item safe for now. When we have collected all the other treasures, we can decide who it belongs to! Do you have any objections to this, fellow Taoists?"

Nanlong Hou was silent for a moment, then calmly made a suggestion.

"I have no objection. I will follow your arrangements!"

The old woman glanced at the scroll and nodded in agreement with a smile.

The other monks had not discovered any other treasures at this moment, so they naturally took it easy.

So, the old man surnamed Yun carefully put the scroll into the storage bag in his pocket.

Chen Yun was gazing deeply at the scroll, in which was hidden a wisp of Master Cangkun's soul. This was undoubtedly crucial for him if he wanted to enter the Demon Valley in the future.

"I must get this scroll."

Chen Yun's eyes flickered, and he muttered silently in his heart.

"Let's go! Let's go to the attic and find out what's going on!" Nanlong Hou looked at the attic, a look of fiery anticipation in his eyes, and said excitedly.

So, the group walked around the altar and came to the small building with its door closed.

This time, Nanlong Hou could no longer suppress his excitement and pushed the door open with force. With a creaky sound, the door opened.

The dazzling spiritual light suddenly came towards them, causing all the monks present to need to adapt for a while before they could regain normal vision.

What caught everyone's eyes was the first floor hall of the attic, which was filled with three long ebony stands, on which a wide variety of items shone brightly, emitting a breathtaking brilliance. (End of this chapter)
