Elder Nanwen took Bai Yang to a hidden secret room in his Dan Pavilion, which was dazzling and had all kinds of rare treasures stored on the shelves, which surprised him. Among them, there are rare heavenly and earthly treasures such as the flame dragon marrow, the nine cold ice stones, and the blue lotus of the hidden pool, which are fragrant and fragrant, shining and shining, which is eye-opening.

Seeing Bai Yang's astonished eyes, Elder Nanwen said proudly: "These heavenly and earthly treasures were either obtained by me at a risk, or they were purchased at a great price, and they can be used as alchemy materials. It's just that I haven't researched a suitable pill to use them yet, and I don't feel safe in a storage ring, so I'm storing them all in my secret treasure vault. ”

Bai Yang asked suspiciously, "Elder Nanwen, since this secret treasure vault is so important to you, and you are afraid of being coveted by others, why did you take me here?"

Nan asked Elder Zhengse and said: "That's because I believe in you, I have seen many people in my life, but there has never been a person whose eyes can be as pure and beautiful as you, obviously you are a person with a pure state of mind." And you are still an alchemy wizard, my life is limited, I hope you can inherit my alchemy and carry it forward!"

Bai Yang nodded and said, "Since Elder Nanwen believes in me so much, I will naturally study your alchemy and become a top alchemist!"

Elder Nanwen said with relief: "That's good, you come with me, I'm going to hand over an important thing to you!"

Soon Elder Nanwen guided Bai Yang to the desk in the middle of the secret room, there was a secret compartment inside, he took out a book called the Yin Yang Dan Sutra and solemnly handed it to him. He asked in amazement, "What is this?"

Elder Nangong Zhengse said: "This Yin Yang Dan Sutra is a Dan Sutra handed down by a certain alchemy power in Taiji Gate, I have spent my whole life trying to understand it thoroughly, but your talent and qualifications are so extraordinary, I believe you will be able to fully master it, and sooner or later you will become a real alchemy power!"

Bai Yang couldn't help but be surprised when he heard that this Yin Yang Dan Sutra actually had something to do with Taijimen, and he inadvertently inherited the favor of Taijimen, which had long since perished. He understood that it must be extraordinary, and he felt heavy in his hand, and asked helplessly, "Elder Nan, is it really appropriate to hand over such an important Yin Yang Dan Sutra to me?"

Elder Nan Wen didn't have a trace of pity, but said with relief: "I have read all this Yin Yang Dan Sutra, I can't comprehend it at all, and it is in vain to continue to keep it, it is better to give it to someone who can really play its role." But don't reveal its existence after you get it, otherwise the other alchemists will go crazy to snatch it!"

Bai Yang asked curiously, "Elder Nan, what is so special about this Yin Yang Dan Sutra?"

Elder Nan Wen said with a serious gaze: "Because this Yin Yang Dan Sutra involves a lot, and all kinds of rare things are recorded in it, which not only involves the life and death of Yin and Yang, but also involves the heavenly machine, and may even be able to take your life against the sky!"

Bai Yang was dumbfounded when he heard this, and his voice trembled: "This-this Yin Yang Dan Sutra is so powerful?"

"It's because it's so powerful, so only the top alchemy wizards can comprehend it thoroughly, and the rare things recorded in it are impossible for me to find them even if I spend my whole life. My abilities are limited, and I'm already old, so I'm going to die after all, so it's better to leave it to a talented young man like you who can be trusted!" Elder Nan Wen said with a sigh.

Bai Yang suddenly felt a heavy responsibility, so he gladly accepted: "Okay, Elder Nanwen, I will accept this Yin Yang Dan Sutra, and I will definitely comprehend it well when I have time!" Soon he put in his storage ring, and Mo Yin heard that the Yin Yang Dan Sutra had a great origin, and he immediately couldn't wait to check it.

Elder Nanwen nodded and said: "Okay, I will entrust it to you, you can comprehend it when you have time, it also records several refining methods of the Tribulation Spirit Pill, the rare treasures I have placed here are for refining the Tribulation Spirit Pill for backup, and I hope you can create a new miracle for me and refine the Crossing Tribulation Spirit Pill of perfect quality!"

As the first alchemist of the Yin Yang Sect, Elder Nan Wen's lifelong pursuit was to refine the Tribulation Spirit Pill with his own hands, so that he would die without regrets. After that, the two left this secret treasure house, and Bai Yang said goodbye to him and returned to the Phoenix Pavilion.

This time, Bai Yang was going to officially go to the Nihuang Master, and let her take her to the deepest part of the Yin Yang Mountain Range to find the traces of the soul of the divine beast and solve the phoenix soul curse for him. Now he could feel that his soul had been eroded by this curse for nearly half, and he occasionally had a headache, if it weren't for the innate strength of his Yang Dao soul, he might have been gone.

When Bai Yang came to the room of Nihuang Shizun, he saw her still slender and mature beautiful figure, and immediately stepped forward to greet him: "Master, I'm here to find you!"

Nihuang Master Venerable naturally understood Bai Yang's intention to come, and asked gently: "Bai Yang, the deepest part of the Yin Yang Mountain Range is very dangerous, I wasn't sure to go there before, but since I was refined by you Phoenix Heart, I just broke through to the strength of the Dao Emperor Double Heaven, I should be able to try to take the risk, you have to follow me closely!"

Speaking of this, Nihuang Shizun unconsciously blushed, and whenever she mentioned the phoenix heart, she would think of the beautiful scene of lingering with Bai Yang with anxiety. And this time I went to the Yin Yang Mountain Range to be alone with Bai Yang, I didn't know how to face him, and my heart was pounding with excitement.

Bai Yang, who was the person concerned, naturally didn't feel the abnormality of Nihuang Shizun, and said with a sunny smile on his face: "Well, Shizun, don't worry, I will follow you closely and will not hold you back!"

After Master Nihuang calmed down, he said lightly: "Okay, let's leave right now!"

So Nihuang Shizun left the Phoenix Pavilion with Bai Yang and went to the back mountain of the Yin-Yang Gate, where there was a secret entrance to the Yin-Yang Mountain Range, which only the people of the Yin-Yang Gate knew. After some rushing, the two of them passed through the barrier of the back mountain and entered the Yin Yang Mountain Range, which was impressively outside a high mountain on the periphery of the Yongyang Forest.

If the disciples of the Yin-Yang Gate carry out the task of hunting demon beasts, they will enter and exit freely from here, and the two of them did not disturb the low-level demon beasts along the way, and came all the way to the interior of the Eternal Sun Forest unimpeded, which is where the demon king-level demon beasts haunt. They all have their own territory and are generally closed to the door unless someone invades or goes out to forage for food.

Nihuang Master Zun Zhengse said: "Although these demon king-level demon beasts are nothing to me now, they are still a bit troublesome to deal with, let's try not to mess with them, let's go to the deepest part of the Yin Yang Mountain Range!"

Bai Yang asked suspiciously: "Master, I remember that there should be the existence of the Immortal Fallen Mortal Hall in the deepest part of the Yin Yang Mountain Range, when I walked out of there, I found that both sides of Yangguan Road were abysses, and I also found a terrifying big bird, are we going to go to the bottom of the abyss this time?"

Nihuang Shizun nodded and said: "Well, the abyss is where the demon emperor-level demon beasts live, Baiyang, the big birds you found are probably one of them, they have become human, and their strength is strong, I didn't dare to enter there at all in the past." But now that I have become the Dao Emperor and you have been cursed by the Phoenix Soul again, I have decided to go inside and break in!"

Bai Yang continued to ask curiously, "Master, how do you know that there may be a divine beast soul under that abyss?"

Nihuang Master Venerable asked lightly, "Bai Yang, do you know what the name of that abyss is?"

Bai Yang shook his head to indicate that he didn't know, and Master Nihuang said solemnly: "That abyss is called the Burial Abyss, and it is said that there are many immortal signs and miracles buried in it, so there are so many demon beasts above the Demon Emperor level gathered in it, wanting to compete for opportunities. Since there are immortal signs and miracles inside, then it is also possible that there are divine beast souls haunting!"

Bai Yang was dumbfounded, he didn't expect that the abyss to come from was so big, it seemed that there should be the deepest secret of the Yin Yang Mountain Range hidden there, no wonder even the Immortal Fallen Mortal Hall was established in it.

Then Nihuang Shizun suddenly remembered a past incident, sighed lightly and said: "Before, in order to suppress the backlash of the phoenix's heart, I took Ning Dan to take the Ice Dragon Source from Bingjiao's hands, but she was poisoned by Bingjiao's cold poison. Bai Yang, fortunately you helped both of us solve the problem, otherwise I would have to come here to risk competing with the Ice Jiao, but after such a long time, I estimate that those two Ice Jiao should have used the Ice Dragon Source and entered the Burial Abyss!"

Bai Yang was surprised when he heard this, and finally understood the reason why the Nihuang Master had seized the Ice Dragon Source was originally to suppress the backlash of the Phoenix Heart. However, she did have some grudges with those two Ice Jiao, they made her beloved disciple Yin Ning Dan endure the cold poison of the Ice Jiao for a year, and they did almost take the culprit of their Ice Dragon Source.

If they meet, it is estimated that the enemy will be extremely red-eyed and have to fight to the death. However, it is not yet in the abyss of burial, and everything is too early to be decided, and I can only hope that I can go deep there safely and without incident.

The two of them cautiously passed through the territory of those demon king-level demon beasts, and did not disturb them, so they were not attacked... Attack, and soon came to the deepest part of the Yin Yang Mountain Range, outside the Burial Heaven Abyss. Looking at the huge crack abyss across the sky, the wind is raging below, the clouds and mist are shrouded, and the ethereal danger makes people tremble at a glance.

Nihuang Master Zun lightly ordered: "Bai Yang, let's fly down together, you hold my hand, be careful!" Soon the phoenix fire shield opened around her, pulling Bai Yang into it, and then turned into a meteor and galloped down, after becoming a Dao Emperor level powerhouse, she could fly freely without the wings of the phoenix.

So the two of them rushed directly into the Gangyun clouds, and they didn't know what the situation was in the abyss below......
