In the formation, the two men stared at the small stone house in a daze.

"How could there be a stone house in this mystic realm? Could there be someone staying here?" Cang Ling asked doubtfully.

"I'm not sure." Cang Yun shook his head. He immediately took a couple of steps forward and gently touched the surface of the stone house. Immediately, a rock fell from the surface and turned into powder.

With a frown, Cang Yun said, "This stone house has been here for a long time. Even if there is someone living here, it should have been here a long time ago."

"A long time ago, could it be …?" Cang Ling was shocked. He seemed to have thought of a conjecture that shocked him as well.

"Rumor has it that this secret realm is the residence of the Venerable Immortal Yang. Your guess is not without reason." Cang Ling understood Cang Ling's thoughts and nodded. However, she then continued, "However, legends are still legends. No one knows how much truth lies."

"Let's go in and take a look. Maybe there's an answer inside." Cang Ling nodded before the two of them pushed open the stone door and entered.

Rumble! *

Accompanied by a deep rumbling sound, the stone door slowly opened. A wave of the aura of time blew over from within.

Within the stone house, a gentle light shone down, causing the entire space to be illuminated. Cang Yun raised his head slightly and saw that the entire stone roof was filled with night pearls the size of goose eggs.

Below him was a neatly placed table and chair. On the table, there were a few scattered jade slips on the dusty surface. Other than these, there was nothing else in the room.

"Brother Yun, quickly take a look at what's written on the jade slip." Cang Ling was a little excited. As she spoke, she swiftly grabbed a jade slip and opened it to examine it.

Cang Yun nodded and grabbed another jade slip as well.

As the jade slip unfurled, one could see one strange symbol after another. It was the size of a tadpole, but the patterns on it were extremely complicated. Just looking at it made one feel dizzy.

"Brother Yun, what is this? I don't understand a single symbol." While Cang Yun was immersed in his thoughts, Cang Ling complained with a bitter face.

"These are formation patterns used to set up the formation." Cang Yun smiled.

"Rune? No wonder I don't understand. Are these jade slips valuable? " Cang Ling shook her head helplessly and asked.

"To you, it is worthless. Naturally, it is useful to me. However, the actual value of this formation will depend on what is recorded in it." Cang Yun gently wiped the dust off the surface of the jade scroll as he said with a smile.

The dao of formations was endlessly profound, and different formations had all sorts of unfathomable uses. Moreover, they were divided into different ranks according to the lowest to the highest. Thus, before he could understand them, Cang Yun was unable to determine their actual value.

"Alright then. We're all destined to be trapped here tonight anyway. Brother Yun, you should study it first." Cang Ling placed the jade slip in her hand back on the stone table. She no longer had the mood to continue studying it and randomly found a place to lie down.

"Remember to pay attention to the Sensory Orb."

Cang Yun nodded his head and gave a reminder before once again sinking his consciousness into the jade slip.

Arrays were a special method that used array patterns to communicate with the power of the heavens and earth, thus forming a special method. The range of the array formation was extremely large, and it was mainly divided into attack, defense, and support types, with different combinations of array patterns being able to form different array formations, thus each type of array pattern arrangement was unique and unique. This also determined that every array master was a master that had inherited their knowledge, otherwise, it would be impossible to create an array formation based on their own talent.

As for the rank of array formation, it corresponded to the rank of array master. From low to high, it was divided into nine grades.

According to Cang Yun's knowledge, in the entire continent, array masters held an extremely high position, even higher than alchemists. Any array master would be roped in by various factions at all costs.

Since formation masters were able to receive such treatment, it was naturally due to their rarity and usability, and the conditions were extremely harsh.

First of all, he had to be a Soul Cultivator, and second of all, he had to have a master.

As for the continent, due to the reverence of formation masters, every formation master held themselves in high regard and valued their own inheritances highly. They wouldn't casually impart knowledge of their formation to others.

Thus, in order to become an array master, besides the talent to cultivate the soul, the most important thing was the inheritance of the formation spell. And now, such an opportunity had appeared in front of Cang Yun.

Time slowly passed. In the blink of an eye, six hours had passed.

At this time, Cang Yun, who had been immersed in comprehending the jade slip, raised his eyebrows and finally moved.

With a swipe of his hand, he took out several milky white formation stones from his storage ring. At the same time, he held a tiny dagger in his hand and began to slowly carve on the formation stones.

The strokes were extremely slow, but they did not show any signs of stopping. Gradually, one by one, extremely complex patterns of array patterns began to take shape.

Formation patterns were the key to laying down formations. Array masters needed to understand every formation pattern thoroughly, and not only must there be no differences in their shapes, they also needed to engrave their spirituality into them. This required an extremely high talent, and those with excellent talent would be able to comprehend a formation pattern in a short moment, while those with low talent would need a very long time to comprehend it.

An hour passed, and finally, the formation stone Cang Yun took out was completely filled with runes.

At this time, Cang Yun waved his hand and threw the formation stone in his hand to a specific spot around his body.

Weng! *

Suddenly, the stone started to emit a milky white halo of light. Then, a mysterious aura started to spread out and the surrounding Origin Energy started to tremble. Then, it started to be attracted toward the stone in an unending stream.

Cang Yun was inside the array, and he could feel the surrounding heaven and earth origin energy becoming denser and denser. He was extremely excited in his heart.

"So this is a formation? It is indeed extraordinary. However, it does not seem to be as difficult as the legends say."

This allowed Cang Yun to have a new understanding of his own talent. However, he was not too surprised by this, after all, he had directly awakened five soul imprints back then, and his mental strength talent far exceeded that of ordinary people.

"Brother Yun, what's going on?"

At this moment, Cang Ling also felt something strange. He stood up and walked to the edge of the formation that Cang Yun had set up, as a bewildered expression appeared on his face.

"It's nothing, there's a source gathering array set up. You should come in and take a feel as well." Cang Yun smiled and explained.

"Origin Gathering Formation?"

Blinking his eyes, Cang Ling's gaze towards Cang Yun instantly brightened. This formation was a treasure used by cultivators.

"Brother Yun, did you arrange this?"

After walking into the array for a while, Cang Ling licked her lips and said with an incredulous and excited tone in her young and tender voice.
