In the treasure exchange room, Cang Yun's mouth was parched. Facing these treasures, he was like a beggar entering a city. The shock and restlessness in his heart could not be quelled for a long time.

Even his exhausted Mental Energy was shaken!

After a few minutes, Cang Yun finally calmed down and started thinking again. Back when he bought the domain jade slip, he had calculated that he would get 101,120 Immortal Yang sword tokens in total.

In other words, killing the Fire Bird had given him a total of a hundred thousand sword tokens!

And after that, he spent one thousand and eight hundred jade strips to purchase the creative concept for Cang Yue. He himself used another two thousand, which meant that he still had ninety-six thousand three hundred and twenty sword commands left.

Without a doubt, this was an incomparably huge amount of wealth!

The following Origin Crystals, the exchange rate for a sword command, was practically enough to form a mountain. If they were to exchange like this and move back to the Vastheaven Realm, even their father would probably be smashed senseless.

However, Cang Yun did not lose his head because low-grade Origin Crystals were only the lowest and most worthless of the many treasures here. With the density of Origin Energy in the Immortal Yang Sword Tower, treasures of this level would not be of any use at all.

And the truly precious treasures, would make one's heart ache incomparably!

Soulstone – 300 sword tokens!

Yang Flames Jade Marrow – 10,000 sword tokens!

"This price is so outrageous!"

Cang Yun smiled bitterly and shook his head. His originally restless heart instantly became cold …

The Soulstone was the milky white stone that Cang Yun used to recover his Spiritual Energy. The name was also chanced upon by Cang Yun, but the price was astonishing.

Three hundred sword tokens for one soul stone, and one soul stone could only be used for one day of consumption. If this was the case, in three months time, a total of twenty-seven thousand sword tokens would be required!

Twenty-seven thousand sword commands! Just how terrifying was this number?

Without a doubt, among all the trial challengers, besides Cang Yun, no one else would be able to afford a single spirit stone!

At this moment, Cang Yun finally understood how heaven defying the opportunity that he had picked up back then was!

As for the other treasure, the 'Sun Flame Jade Marrow', according to the description, this treasure contained an extremely powerful Yang flame energy. This was also what Cang Yun needed to cultivate his pure Yang body, but the price was even more terrifying!

Other than this, there were also some extremely precious items. However, Cang Yun did not pay them any more attention. He was truly afraid that he would not be able to injure them when the time came …

"I'll first exchange for spirit stones. As for the Yang Flames Jade Marrow, I'll wait until I've comprehended the Immortal Yang Sword Dao Concept to a certain level before I exchange it …"

After some consideration, Cang Yun prepared to exchange for the Spirit Stone. After all, this was the thing that he desperately needed right now.

With a thought, Cang Yun exchanged for ten soul stones. In an instant, three thousand less sword commands were exchanged; then, after hesitating for a moment, Cang Yun used another three hundred and twenty sword commands to exchange for three hundred and twenty low-grade Origin Crystals. Then, as if fleeing for his life, he left the treasure exchange room.

There were still ninety-three thousand sword commands left …

After returning to the stone room, Cang Yun heaved a sigh of relief. The way he spent money like a flood had made his heart ache even though he was always frugal.

However, he did not immediately start cultivating. Instead, he took out all three hundred and twenty low-grade Origin Crystals and placed them on the ground. Afterwards, he took out the bag he was carrying and took out the Purple Gold Wild Egg inside …

Gently stroking the smooth surface of the egg, Cang Yun felt the fluctuations of life from within and revealed a trace of affection, as if his mind was connected to it.

These past few days, Cang Yun had been busy with the immortal palace test and didn't have enough energy to feed this violet gold cub, causing its growth speed to be significantly slower.

"Kid, I've let you starve for so many days. This time, I'll let you swallow your fill!"

As he spoke softly, Cang Yun placed the Purple Gold Wild Egg on top of the Origin Crystal. In that instant, he felt a joyful feeling coming from within, and immediately after, a suction force began to emanate from the surface of the egg, greedily absorbing the power of the Origin Crystal.

Cang Yun stayed there for a while longer. After seeing that the purple-gold colored egg was absorbing the energy at an orderly manner, he smiled slightly and finally let go of the worries in his heart.

Next, it was time to start comprehending the Immortal Yang Sword Dao …

The next moment, Cang Yun's cultivation was back on track.

Savage Wasteland, surging rivers.

The Hierarch Xianyang brandished his sword again and again as the azure cloud stood thousands of meters behind him, silently observing his sword posture and quietly comprehending the intent within.

One Slash...

Two Swords...

The concept of time gradually became blurred in Cang Yun's mind. In his pupils, there were two burning suns and as time passed, they became increasingly turbulent, as if an extraordinary power was rapidly awakening.

As for Cang Yun, he had sunk into the long river of the Immortal Yang Sword Dao's domain …

At the same time, in another stone chamber of the Immortal Yang Sword Tower, there was a person who was currently challenging his limits.

He was none other than Xu Guang.

It had been two days since he entered this secret chamber. Two hours ago, Xu Guang had once again entered the Concept jade slip.

Within his consciousness, there was another silhouette, waving the blade in his hand.

That person was dressed in a black robe with a big word 'Demon' on it. The word was dark red in color and looked like it was made of blood. When the wind blew, one could even smell the blood on it.

The man in black wore a dark expression. His body was like a rotten log, black and cold. There was not a single trace of blood in his body. His pupils were like the abyss of evil, emitting an incredibly bloodthirsty light.

A wisp of dim light rose up and the black cloaked person's sword, like a dormant poisonous snake, suddenly revealed sharp fangs from within the darkness. It was vicious and evil.

Xu Guang, who was standing behind the man in black, was mesmerized by what he saw …

He could naturally tell that the black-robed figure's sword dao was the sword of evil, but he paid it no heed.

The thirst for power in Xu Guang's heart had completely overshadowed everything else. Justice and reason had long since been tossed out of his mind.

The black-clothed person's martial arts Concept was very compatible with his own. Although he didn't know why, he didn't consider that as long as he was bestowed with endless strength, he would give up everything for it!

This was Xu Guang's true intention in his heart, and also his martial way!

And the truth proved that he was truly suitable for this path. This was because perceiving the black-clothed person's martial arts Concepts was as straightforward and refreshing as a fish in water. He wasn't as difficult as others in perceiving other Concepts.

It was because of this that he was able to gain enlightenment for so long each time. His spiritual energy was not too depleted, and his improvement was naturally at a tremendous pace.

"I will trample everyone under my feet! Use your blood to achieve my supreme Sword Truth! "

A ripple appeared in Xu Guang's heart, and his lips curled up into a sinister, evil smile, just like the black-robed man's …
