The primal wilderness surged with torrential rivers.

Cang Yun once again entered the projection of the Immortal Yang Sword Dao into the jade slip. Ahead of him, the Venerable Immortal Yang stood tall and straight, standing tall and proud.

This was his Sword Truth. Righteous and wild!

Suddenly, the Venerable Immortal Yang raised his sword again and pointed it at the sky. His sword posture did not change at all from the last time.

However, the azure cloud shook violently, and the pure yang energy in his body burned uncontrollably. Two bright suns faintly appeared in his eyes, and in that instant, a mysterious feeling appeared in his heart.

This sword seemed to have become much clearer …

Cang Yun muttered to himself. Then, his eyes turned serious as his mind concentrated like never before! He stared fixedly at the Venerable Immortal Yang's movements, not missing a single detail.

The pure yang energy in his body became more and more intense. It was as if it was moving stupidly!

Weng! *

However, after barely enduring for three breaths, a feeling of dizziness came surging over. The Shining Solar Diagram in Cang Yun's eyes crumbled and he was instantly ejected from the space within the jade slip.

"Hu hu …!"

Returning to his original body, Cang Yun looked like he had encountered a nightmare as he panted heavily in shock. His face was pale and his mind felt a wave of exhaustion that he had never felt before.

A terrifying sword intent!

Cang Yun's heart trembled violently. This time around, his comprehension had allowed him to touch upon the sword intent within. He finally understood how terrifying that sword attack of the Venerable Immortal Yang was. And because of that, his mental strength was unable to withstand it. Just by comprehending the stance of raising the sword for three breaths, he was no longer able to endure.

"Three breaths of time and my spirit power is depleted. I will need at least half a day to recover... If I continue meditating like this, let alone March, I'm afraid that even if I were to spend three years meditating, I still wouldn't be able to truly comprehend this sword strike! "

Cang Yun endured his exhaustion and thought to himself …

In the next moment, he gently touched his storage ring. Immediately, a thumb-sized, milky-white stone that was emitting a dense luster appeared in his palm.

This rock was faintly filled with a strange aura and under the nourishment of this aura, the empty Spiritual Energy within Cang Yun Sect was actually slowly recovering.

Cang Yun was unable to contain his joy at seeing such a miraculous scene unfold before him.

This stone was what Cang Yun obtained after killing the spirit beast. He didn't know what the stone was used for, but it seemed to have something to do with the soul, so he had carefully kept it.

And now, the aura emitted from the stone proved his conjecture — this stone could recover the spirit energy that it had consumed!

"This thing is extraordinary!"

Cang Yun thought to himself for a moment before deciding on the definition of this stone. This was because Cang Yun had done his research on heavenly materials in the world. As long as it was a treasure related to Mental Energy, it would be an extremely valuable existence!

I don't recognize this thing... First, let's call it the 'Soul Stone' …

After giving the stone a name, Cang Yun no longer hesitated. He circulated his cultivation method and a suction force appeared in his palm, crazily absorbing the energy from the 'Soul Stone'.

Slowly, Cang Yun's depleted spiritual energy was being rapidly recovered … "UU …"

Thus, after a quarter-hour, Cang Yun's complexion returned to a ruddy color and his mental force returned to its peak state!

"It is indeed extraordinary!" Cang Yun sighed in admiration. This kind of recovery rate was a bit beyond his expectations …

However, Cang Yun also noticed that after he used it this time, the 'Soul Stone' had clearly dimmed a little. It was obvious that the energy of the 'Soul Stone' was also limited and it wouldn't be able to last for long.

In this regard, Cang Yun did not feel the slightest bit of regret. What was useful was called a treasure, and the best way to use good steel on the blade was to use it. Right now, it was the critical time for him!

Weng! *

In the next moment, Cang Yun's consciousness sank into the jade slip again …

Four breaths later, Cang Yun walked out with a pale face.

On one hand, because the suppression from the sword intent had tempered the Azure Cloud Divine Soul, it had become much more tenacious and tenacious. On the other hand, as his comprehension deepened, the pressure from the sword intent would also become smaller and smaller.

Without any hesitation, he took out the 'Soul Stone' once again and started recovering …

Then he went back into the jade.

Five breaths later, he withdrew again …

Six breaths …

Seven breaths …

Gradually, time passed in this cycle …

In the blink of an eye, one day passed.

This time, Cang Yun endured for two full minutes before tiredly withdrawing from the jade slip.

Looking at the soul stone in his hand, Cang Yun shook his head with a bitter smile. This was simply too wasteful, and he had only comprehended a little of the Immortal Yang Sword Dao, he hadn't even stepped through the threshold.

However, it wasn't as if Cang Yun hadn't reaped any rewards. He felt that he had already faintly found a path to martial arts Concepts. All he needed was time to slowly make it to that step.

But he also knew that if he didn't have the assistance of the 'soul stone', he would still need to walk on this road for a long time. And this period of time was exactly what he couldn't afford to delay any longer, because the time he studied the jade chip was only three months.

"Looks like I can only try my luck over there …"

In the next moment, Cang Yun shifted his gaze to the stone door at the side of the stone room. That was the Immortal Yang Sword Tower's treasure exchange room.

Cang Yun stood up, forcefully suppressing his mental exhaustion as he slowly walked forward. He then extended his hand to push open the stone door.

Rumble rumble rumble!

A heavy sound of the door opening echoed in the room, and a dazzling light appeared before Cang Yun's eyes.

Inside the treasury, numerous treasures were neatly placed on a row of stone shelves. With a rough sweep of the shelves, the number of treasures could be estimated to be no less than a thousand. These treasures were all covered by a pale-blue light barrier. Clearly, someone had set up a barrier. Numerous prices had also been neatly marked out on the light barrier.

Low-grade Origin Crystal – a sword token.

Medium-grade Origin Crystals — ten sword tokens.

High-grade Origin Skill — A hundred sword tokens.

Grand Origin Pill – 100 sword commands.

As his gaze swept across the area, Cang Yun felt as if he was in a bright starry sky. The dazzling light emitted by the surrounding treasures was like stars in the night sky, dazzling him.

All kinds of treasures could be found here. There were many different kinds of treasures that one had never seen before, and even some that one had never heard of. It was simply inconceivable.

Cang Yun's throat rolled a little. Despite his extraordinary mental fortitude, his eyes couldn't help but burn at this moment. The collection of the Venerable Immortal Yang was truly shocking … One had to know that this was only the treasure room of Cang Yun's stone room. As for the other treasure rooms, there were at least dozens of them.

This kind of wealth, was simply exaggerated … In fact, Cang Yun had no doubt that even if he sold his entire Vastheaven Realm, including its people, he would not be able to obtain that many treasures!
