"I've thought it through. If I don't save her, my heart will never be at peace for the rest of my life."

Cang Yun's expression was firm as he answered Murong Nantian word by word.

"Alright, I'll tell you the method then, but you know about Sayo's situation, so you can only do your best and obey the will of the heavens. If you cannot do it, don't force it, you still have a long way to go …" He didn't think that Cang Yun would be able to fulfill this promise because with Murong Yi's current situation, even if the entire Murong Family were to go all out, they wouldn't be able to change the outcome. Therefore, he didn't want Cang Yun to pay too much of a price.

However, Cang Yun did not reply him. He clenched his fists even tighter, and his expression was firm.

"Forget it." Seeing that, Murong Nantian lightly shook his head and sighed. Then, he said, "I'm sure you know a bit about Sayo's body. The Absolute Yin Ice Body is the coldest body in the world, and it has the most yin energy since birth."

"You saw this power with your own eyes. There is no doubt of its strength, but to control this power, the price one has to pay is unimaginable. Little Yi's current situation is to forcefully use the Supreme Yin Qi that has been sealed within her body for many years, and is suffering from a backlash caused by it being unable to control the Supreme Yin Qi. "

According to the ancient records, this situation can be roughly divided into two stages. The first stage, the Supreme Yin Qi corrodes the body, causing the person to be in a state of false death, which is exactly what is happening to Sayo now. The second stage, is where the Supreme Yin Qi starts to erode the soul.

"And for these two stages, according to all the records, the longest period of time that existed in history did not exceed five years. That is to say, we only have five years at most to save Sayo."

"All these years, I've been reading a bunch of books and found a relatively reliable method to revive Sayo's physique. That is, using the power of the extreme yang of heaven and earth to deal with the extreme yin and yang in her body, only then will there be a sliver of a chance."

Lone Yin was not long. Solitary Yang was not born. Yang energy could weaken the Yin energy within her!

After hearing what Murong Nantian said, Cang Yun nodded his head. This method did have its roots and a good chance of success, and he also cultivated pure Yang energy.

Pure Yang was the most powerful Yang in the world. It just so happened to be able to fight against the yin energy in Murong Yi's body. This made Cang Yun feel slightly happy in his heart.

"Don't be happy too early. I know you've coincidentally cultivated pure Yang energy, but to save Sayo, your current strength is still far, far lacking." Murong Nantian also saw through Cang Yun's thoughts. He immediately poured a bucket of cold water over him.

"The Yin energy in Sayo's body is the Yin energy from the moment she was born, and the Yin energy in her body is already perfect. However, the pure Yang energy in your body is at the Pre-Sky Realm, and it's too weak, so it's impossible to dissolve her Yin energy."

"If you want to reach that step, you must have a full mastery of the Yang energy in your body to have the chance. Otherwise, your impure Yang energy will cause her yin energy to rebound. Not only will it not save her, it will also hasten her death."

"As for the difficulty of achieving the Great Perfection of the Pure Yang Body, I believe you know it even better than I do. In the long history, I only know that the Venerable Immortal Yang has reached such a level …"
