"What a terrifying strike!"

Blue Cloud retreated back into the stone room, his chest heaving violently as his palm that was holding onto the sword began to sweat profusely.

The strike of the black-robed youth was truly terrifying. Not only that, but within that black clothed youth's sword attack, Cang Yun could also feel a power that made his heart palpitate. This power pressured against his mind, making him unable to resist as he could only retreat.

"Is this the Concept of the Sword? How terrifying!"

From the exchange just now, Cang Yun had already sensed that this black-clothed youth's cultivation base was only at the fourth layer of cultivation, which was comparable to his. However, his sword arts had reached a terrifying level, and it was obvious that he had comprehended the sword concept. Cang Yun did not doubt that if this person wanted to kill him, he would at most need two strikes, or even a slash!

Ever since Cang Yun recovered his strength, he had relied on the advantage of his unique source energy to be almost invincible at the same cultivation level, even fighting those who were stronger than him. But today, facing this black-clothed youth who was of the same cultivation level as him, he had lost, and not only had lost, he had lost miserably, and could be said to be completely powerless to fight back.

This was the first time that he was able to deeply realize just how terrifying the Concept of Martial Arts was!

"I must successfully comprehend the Concept of Martial Arts!"

At this moment, Cang Yun's heart was filled with boundless desire. He looked at the energy sword in his hand that was gradually disappearing. Then, he raised his head and stared at the empty stone staircase, his eyes filled with the desire to do battle.

"In ten days at most, I will definitely defeat you!"

After saying that, Cang Yun walked back to the center of the stone chamber and sat down cross-legged. The Immortal Yang Sword Tower had a total of nine floors for this test, which lasted three months. If one could not even pass the first level in ten days, then there was no hope for them to pass the test, so Cang Yun set a goal for himself!

One of them recorded the concept of martial arts. As for the other one, Cang Yun did not know what it really was, but if two jade slips were to be exchanged for a set, then there must be an inseparable connection between the two.

Cang Yun took a deep breath. When his mind had completely calmed down, he reached out and picked up the jade slip that contained the Concept of Martial Arts.

The jade slip unfurled, and his mind entered it.

In that instant, the scene changed …

Cang Yun arrived at a wasteland. The wasteland was verdant and lush, as far as the eye could see. In the distance, there was a surging river. The river surged and churned, splitting the wasteland in half.

This was an incomparably spacious land, so spacious that when the azure cloud entered, it was like a tiny bird in the sky.

Suddenly, a figure appeared in the vast horizon and slowly approached.

He wore ordinary blue clothes, and it was impossible to see his face clearly. As his long hair recklessly fluttered in the wind, he held a four foot long sword in his hand as he landed on the desolate grassland.

This figure couldn't sense any source energy aura from his body, but his waist was perfectly straight, like an unsheathed sharp sword, and his entire body was emitting a sharp aura that shot into the sky!

In the next moment, two divine lights shot out from the pupils of those blurry cheeks, like lightning streaking across the horizon.

The silhouette remained silent as the longsword in his hand clanged, pointing straight at the heavens!

Swish!

As the sword cut down, the heaven and earth suddenly paled. A three foot sword light shot out, and the source energy of heaven and earth roiled over like a whale drawing water. In the blink of an eye, the three foot sword light turned into an unfathomable force!

This sword was like a blazing prairie fire. The momentum of this sword grew more and more intense!

At the same time, on the sword's body, raging yang flames burst into flames and spread outwards, covering the 100,000 foot sword light. In an instant, a boundless aura that could destroy the heavens and the earth was born.

Rumble rumble rumble!

The sword light sliced through the sky.

In just a split-second, Hundred Spirits lost their hearing, and the heaven and earth changed color. As Cang Yun stood in the distance, all he could feel was a sword ray as hot as the sun, filling the entire space.

That might, even if it was just a projection, made all the hairs on his body stand up uncontrollably. It was as if he had been locked on, his heartbeat and breathing stagnated, and in the next second, he would be shattered by that heaven-shaking sword intent.

Cang Yun's consciousness instantly became blurry, like a small flame swaying in a gale. It seemed as if it could be extinguished at any moment.

In that blurry consciousness, he could vaguely see that on the ground, there was a black ravine that was several tens of thousands of feet long. It was growing deeper and wider.

Following the direction of this ravine, one could see that, in the distance, the river had cut off its course. The surging river had stirred up monstrous waves, but no matter what one looked at it, they were unable to leap over that abyss, as if there was an invisible force blocking it, preventing it from calming down for a long time.

Cang Yun's consciousness became increasingly blurry. The sword intent that filled this entire area rejected him, and he could feel that if he still did not leave, those sword intents would ruthlessly tear him apart.

As such, Cang Yun no longer resisted, and his consciousness gradually left this space.

At this moment, the green figure turned around as if he had sensed something. His gaze seemed to have surpassed the obstruction of space and crossed the long river of time …

Finally, at the final moment when Cang Yun's consciousness was about to disappear, the green figure's voice sounded:

"To refine this sword, I'll first learn Pure Yang."

Weng! *

As the sound of his voice faded, Cang Yun's consciousness returned to his body once more.

"Phew …" "What a terrifying sword intent, what a terrifying person!"

Cang Yun woke up, and panted heavily. He only glanced at the projection once, but it was as though he had experienced a battle of life and death. His mind was extremely exhausted.

At the same time, the shock in his heart could not calm down for a long time. Previously, the sword intent of the black-clothed youth who had made it to the second level had made him feel terrifying.

A single sword strike tore through the earth and cut through rivers!

Such might was simply unimaginable. Compared to the youth's sword intent, the youth in black was like a firefly compared to Haoyue.

"That azure-robed man must be Venerable Immortal Xian Yang!"

Cang Yun muttered to himself, because the aura of the green-robed man was extremely similar to the statue he saw in the palace. He similarly looked down on faces and had the aura of looking down upon the world.

"That sword must be one of Venerable Immortal Yang's secret arts. I must learn it!"

After confirming the identity of Venerable Immortal Yang, the desire in Cang Yun's heart intensified. The Venerable Immortal Xian Yang was a peerless almighty being that ruled an entire era. If such a person's ultimate technique could be comprehended, the benefits would be unimaginably great!

As he thought to this point, Cang Yun suddenly thought of what the Venerable Immortal Yang had told him before he left — To refine this sword, one must first cultivate the Pure Yang Sword!

After pondering for a while, Cang Yun's eyes lit up and his gaze immediately fell on the ancient jade slip in front of him.

Cultivating pure Yang first, the answer might be within …
