In the quiet stone chamber, Cang Yun held an ancient jade slip in his hand, deep in thought.

"Heaven and Earth are split into two, with Yin and Yang revolving. At the beginning of the sun, it is the Pure Yang …" My path of the sword is based on the sword, the sun is my soul, and is called the celestial sun! "

After a long time, when he finished reading the information in the jade, Cang Yun closed it and revealed a look of understanding …

"So that's how it is."

This jade slip contained a cultivation method called the 'Pure Yang Body'. Pure Yang Body was a type of special physique, with this kind of physique, one could possess pure Yang energy, and its might was unparalleled. It was extremely profound.

Meanwhile, the sword dao of the Venerable Immortal Yang was to use pure yang energy to stimulate the sword intent. When the two combined, their power multiplied.

"To refine this sword, I'll cultivate Pure Yang first!"

At this moment, Cang Yun finally understood the meaning behind the words of the Hierarch Xian Yang. The latter's sword dao had already broken away from the pure sword intent, and the pure Yang intent was the foundation!

As a result, in order to cultivate his Sword Truth, he had to have a pure Yang body, and then use the Sword Concept to comprehend the pure Yang Concept. Only by combining the two would he be able to achieve the Immortal Yang Sword Dao!

A single sword strike had fused two Concepts. As expected of the Supreme Celestial Yang, he truly lived up to the name of a peerless genius!

At the same time, Cang Yun also understood why there were so many jades on the seventh floor and above in the palace. They were all exchanged for two of them, because the sword dao had already transcended the realm of pure sword intent and needed the help of special physiques in order to practice it. Just like the Immortal Yang Sword, the only difference was that the sword conception was not as high as the pure Yang domain.

After understanding the relationship between the two, the next step was clear. First, he had to master the 'Pure Yang Body'.

However, according to the description in the jade slip, a pure Yang body was not easy to cultivate. This was because even amongst all the special physiques, this physique was still one of the best. It was difficult to grow in the Xiantian realm, and even harder to cultivate the Houtian realm!

Cang Yun naturally did not have this kind of physique, so he could only use the jade slip's cultivation method to refine his Houtian Pure Yang body.

There was not much difference between Xiantian Pure Yang and Houtian Pure Yang. The only difference was that Xiantian Pure Yang was born with a purer physique, so it was easier to reach the peak of pure Yang body. Houtian Pure Yang was extremely difficult to cultivate.

Cang Yun did not have any other thoughts about this. The innate constitution was bestowed by the heavens and even if one wanted it, one could not ask for it. Furthermore, being able to cultivate the innate constitution was a great opportunity for him.

And if one wanted to cultivate the Houtian Pure Yang body, according to the jade slip, a martial artist had to use the power of the yang flames to wash their marrow. Only then would their body be able to continue tempering and thus become a Pure Yang body!

"The power of the Yang Flames has cleansed the marrow …" Didn't I just happen to finish it … " Cang Yun was overjoyed. He did not expect to meet the requirements for the first step with so much luck.

According to the description of the jade slip, this first step was actually the hardest, because this required the power of yang fire to be moderate in order to obtain such a lucky chance. If there was a bit less, then it would be impossible to satisfy the requirements of clearing the meridians, and a bit more could possibly cause damage to the meridians; it could be said to be extremely difficult to control.

Cang Yun had managed to complete this process in a daze. It could only be said that his luck was enviable.

Whoosh.

Cang Yun took a deep breath. Although he was happy in his heart, he could not help but feel some lingering fear. Back then, he knew nothing about this. If he had not been so lucky, the consequences would have been unimaginable.

Opportunity. Opportunity. The word 'opportunity' was truly marvelous.

At the same time, Cang Yun suddenly thought of another problem, and that was that he had helped Cang Yue choose the same martial concept that required a special physique to cultivate. If that was the case, wouldn't it mean that not only would he be unable to help her, he would also harm her?

After all, it was really too difficult to cultivate a special physique. Cang Yun herself had first obtained the incomparably precious fire lotus, and then, by heaven-defying luck, had passed the cleansing of one's meridians, allowing her to cultivate a pure Yang body. However, Cang Yue did not have this opportunity at all.

If one could not comprehend it, then no matter how precious it was, it was meaningless!

"I never thought that after so much effort, I would end up causing her harm …" Cang Yun felt guilt in his heart, but there was nothing he could do. Now that he had chosen the jade, there was no way he could change it again.

He hoped that she could have her own fortuitous encounter …

Cang Yun shook his head and suppressed the complicated thoughts in his heart. He began to prepare to train in the 'Pure Yang Body'.

The first step in cultivating a pure Yang body was to borrow the Yang energy to cleanse one's marrow and allow one's body to have the nature of a blazing sun. Only then would one be able to continue their cultivation.

Cang Yun had completed this step.

Then, the next step is to continue to use the power of the sun's flames to open the blood cavities around the body, allowing every inch of flesh to be tempered …

According to the jade slip, there were a total of 108 blood orifices, and every 36 blood orifices were divided into one week …

Activating thirty-six blood cavities could form a small cycle within the body, a small cycle within the body. Opening seventy-two blood cavities could form a large circle within the body, a large cycle within the body, a large cycle within the body, a large circle within the body, and finally opening all one hundred and eight blood cavities, one could form a complete cycle, a perfect cycle, and a pure sun body would be complete!

The three realms of the Pure Yang Body seemed very simple, but to truly cultivate it was extremely difficult!

According to the description of the jade slip, these 108 blood cavities were the foundation of the human body. If one wanted to open these blood cavities, they had to use a massive amount of yang energy to do so. Moreover, according to the order of these blood cavities, the later the blood cavities were, the greater the difficulty of opening them. Back then, it was also due to a great opportunity that the Venerable Immortal Yang was able to cultivate the Pure Yang Body to the Great Perfection Stage. The difficulty of this was comparable to ascending to the heavens!

"Even a supreme existence like the Venerable Immortal Yang will find it hard to reach perfection. If I were to truly cultivate it, I don't know how long it would take …" Cang Yun smiled bitterly. Cultivating such a profound physique made him feel a sense of longing.

Fortunately, this jade slip recorded the cultivation conditions of the Immortal Yang Sword Dao. As long as one was able to open one's Blood Meridian, one would be able to cultivate using a sliver of pure Yang energy.

"I only need to open my first Blood Meridian..."

He then took out the medicine box from his storage ring. Inside were the roots, petals, and the remaining eight lotus seeds. These were all precious fire attribute medicines that contained the power of yang flames. Thus, they were all suitable for cultivating a pure Yang body.

Looking at these treasures, Cang Yun finally felt a bit more confident.

"With all of these added together, I should be able to open my first Blood Meridian …"
