Although Huo Shan was a vast mountain, Gu Xueluo and the hidden spirit seemed to feel that they were the only two. The world was small, the affairs of the world were difficult, and they had experienced many vicissitudes of life.

The two of them wanted to return to the Feng Lin Continent as soon as possible, so they followed the path they came from and unknowingly arrived at a small valley. Even though it was called a valley, it was actually just two sides of an open cliff surrounding the city, forming a narrow and deep space.

"What is this place? We clearly didn't pass here when we came here." The spirit said in surprise.

Gu Xueluo was also a little puzzled. "That's right. Even though I've been to Huo Shan a few times, I've never seen this place before. It's a little strange."

When the two of them looked closely, they discovered that there were strange lines of characters on the cliff. They seemed to be tombstone inscriptions for sacrifices, but also seemed to be mantra chants of some sort. A gust of wind blew, causing the white dust on the cliff face to fly into the air. The words seemed even more distinct, and the spirit hidden within carefully read the words, because his mind seemed to be somewhat familiar with these words. Huo Shan was one of the most dangerous places in the Celestial Realm. He was a hiding place for rare and precious treasures. The words on the cliff weren't carved out of thin air; they definitely had a origin and origin.

Gu Xueluo hurried forward and said, "Sit down, let me use my internal force to force the remaining black poison out."

The hidden spirit shook its head and said softly, "Don't worry about me. It will be fine very soon. "Huo Shan is filled with power, and even with your inner force, you can only use half of it. You don't have to waste it on me, what if the Three-legged Crow appears again?"

Gu Xueluo said, "Anyway, the Three-Legged Black Turtle won't appear again for the next few days, because it has already retreated back to the nest to recuperate after being injured by us. The other Three-Legged Golden Crow will also protect it."

Suddenly, the hidden spirit remembered that when he first entered Taixuan's capital, his master had taught his seniors and the others how to learn ancient Sanskrit. These characters were strange in shape, complex in structure, and difficult to understand. How similar were the characters on the cliff face to the ancient Sanskrit? Why not use Sanskrit to decipher them?

Thinking up to this point, the hidden spirit suddenly turned around and looked at the strange characters written on the cliff wall.

Gu Xueluo was taken aback by his actions. She had come to Huo Shan several times, but she had never seen this cliff before. She had never heard of a place like this mentioned by Feng Chu Sheng. If one looked carefully at it now, this place was indeed a little strange. Just who had left these words here? How did he get to Huo Shan? What was his purpose in carving these words? A series of questions appeared in Gu Xueluo's mind, and she couldn't help but take another look at these words.

All of a sudden, Hidden Spirit's face was brimming with a victorious smile. As if he had discovered a great secret, he said to himself, "I've discovered it, so it turns out to be so magical!"

Gu Xueluo looked at the hidden spirit in her heart and said in alarm, "This must be a major discovery, or else the normally calm and composed Hidden Spirit would not be so excited. It then asked," What exactly are these words written? Look how excited you are. "

The hidden spirit held Gu Xueluo's shoulders with both hands, and with a somewhat excited expression, solemnly said, "Do you know the supreme secret manual of the Six Realms — — The Profound Yellow Scripture?! The words on the cliff are the first volume of the 'Profound Yellow Scripture'!"

Gu Xueluo was also very surprised when she heard this, but she was also a bit puzzled. She muttered to herself, "I believe everyone in the six realms knows that when the six realms first formed, the leaders of the realms, in order to stabilize the four extremes and overcome the calamities together, gathered all the martial arts essence of the realms and created it together. This scripture's martial arts are profound and unfathomable. After you train it, you will rarely be able to meet an opponent like me! "

Upon hearing Gu Xueluo's words, the hidden spirit seemed to have gained some enlightenment as he said, "When I was in Taixuan, Master also mentioned that this secret scripture has been missing for more than a thousand years. The six realms have been searching arduously for no results."

Gu Xueluo said, "It's not that they went missing, but the Six Realms each took this supreme secret manual for themselves. They fought over it openly and secretly, and each plotted against the other. In the end, the secret manual was destroyed, resulting in the extinction of the Six Realms' greedy possessiveness."

He said in a low voice, "Oh, then will the 'Profound Yellow Scripture of the Heavens and Earth' disappear just like that?"

Gu Xueluo said, "As far as I know, of course not. The 'Heavenly Mystery Yellow Scripture' is divided into four volumes of mental cultivation method, and the 'Superclass of mental cultivation method' is sealed in the Twilight Jade; the third of the four fragments should be with your Master, and the fourth with the Devil's Sword of the Nine Heavens and Devil, the first and second volumes have always been unknown, but the first volume is actually in this place."

"It must be some honorable senior. In order to prevent the Six Realms from fighting over it and in order to prevent the secret manuals from being lost, he carved it on the cliff of this Huo Shan." After saying that, admiration and adoration appeared on his face.

Gu Xueluo thought to herself, "Hidden Spirits are supposed to be the prideful martial artists in Taixuan, and now they're also the Six Realms Emissaries. Their luck, strength, talent, and cultivation are all first-rate." Now, he was the first to discover the first volume of the 'Profound Yellow Scripture of the Heaven and Earth'.

Gu Xueluo quietly stared at the hidden spirit for a while, then smiled and said, "Hidden spirit, being able to find the first volume of the 'Black Yellow Mantra' here is a blessing from heaven. This secret manual was originally prepared for those who practice their martial arts well, you can't cultivate better."

Listening to Gu Xueluo's words, the spirit shook his head firmly and resolutely said, "Absolutely not. The 'Profound Yellow Scripture of the Heavens and Earth' exists in all six realms, so it should be cultivated by all six realms. I can't secretly cultivate just because I found it by a fluke."

Gu Xueluo helplessly smiled bitterly and thought to herself: "This stubborn fool, how can he be so rigid? He is giving us the chance now, and if we miss this opportunity and get cultivated by someone who has a wrong mind, the world would be in trouble." He had to think of a way to make him willingly cultivate.

Gu Xueluo seemed to have thought of something as she quietly said, "Hidden Spirit, if you don't want to practice your secret manual, then we'll hurry up and leave. Because the black poison in your body can't be delayed any longer. It seems like it's already deep into your body."

"It's that serious. Is there any other way to cure it?"

Gu Xueluo deliberately kept him in suspense and continued, "The black poison goes deep into one's body, disturbing one's mind and destroying one's meridians. No matter how strong one's will is, they will still lose their consciousness and go berserk, doing all sorts of things that are not controlled by their will. There are two ways to cure it: one is the spirit of the Qiongqi Beast of the Great Sea, and the other is this《 Black Yellow Classic of the Heavens and the Earth》. "

Hidden Spirit said with a wooden expression, "You have a clever tongue, but you still want me to cultivate the 'Black Gold Scripture of the Heavens and Earth'. It's fine if I don't cure the poison, but you can't let me do something so treacherous as to heal my injuries!"

Hearing that, Gu Xueluo was enraged. The words of the hidden spirit stung her. It was originally for his own good, but not only did he not appreciate her kindness, he even mocked and ridiculed her.

Gu Xueluo was so angry that her tears were about to fall. She said angrily, "What does it have to do with me whether you can cure it or not? Besides, where did he get the trust? Where did the betrayal come from? Do you think that you are the master of one of the six realms? Gu Xueluo's rage had not yet subsided as she continued, "I have seen through you. As a Successor Disciple of the Supreme Profound Capital's Elder, I cannot take responsibility for the safety of the entire Qing Qiu Mountain. "As a man, it's really disappointing that he is so narrow-minded and does not dare to take responsibility!"

Hidden Spirit felt somewhat ashamed of Gu Xueluo's criticism. He understood that Gu Xueluo's words were not without reason. Just as he was about to open his mouth, he was stopped by Gu Xueluo.

Gu Xueluo said, "All you say is that you have the trust of the Six Realms on your lips. Don't you know that the situation of the Six Realms is extremely dangerous? If someone with ill intentions were to discover this secret manual in the future, wouldn't it set off a storm of terror and bloodshed in the Six Realms? At that time, you will be the accomplice and the culprit behind this calamity. Can you bear this responsibility? Now, tell me, where is your duty and morality? "

That's right, if this secret manual's first volume were to be possessed by those with ulterior motives, then wouldn't the world be thrown into chaos, and at that time, when the Six Realms would be in trouble, who could bear the consequences? Thinking of this, Hidden Spirit slowly said, "After your painful analysis of the pros and cons, this secret manual really can't fall into the wrong hands, so I've decided to practice the first volume."

Gu Xueluo forcefully suppressed her joy, thinking to herself that she still had to use this kind of provocation to convince this kind of stubborn person.

The Spirit of Concealment slowly channeled his internal energy, his eyes looking straight at the scriptures on the cliff, and he muttered to himself, "The Profound Practitioners are the ancestors of nature, and there are also large sects. It is deep and therefore is called microcosm. It's far away, so it's called beautiful. Its height covered the nine heavens, its width covered eight corners. "Light like the sun and moon, fast as lightning …"

With the Hidden Azure Sword in hand, the figure danced in an unpredictable manner. The edge of the sword turned into streaks of green lightning. It was vigorous and powerful, extremely powerful.

Then, the spirit put the sword back into its scabbard, stood still, took in a breath of air, adjusted his pulse, and continued, "The only profound way is always the same. "For those who don't know the way of the profound, although we have to focus on the divine tool for killing, the kiss is the key to the rise and fall of the world." It was obvious that this part required training in the palm techniques of the hidden spirits.

The Hidden Spirit said again: "In a trance, it is like a surface. Swallow the nine flowers in the clouds, the six energies in the rosy clouds. "The haiku, who hovers over Xiwei, wriggles and wriggles, and totters around the world, is also one of the winners."

It contains alcohol and modesty, no desires and no worries. It was as if nature had descended upon the world itself. In the vast and boundless world, there was also the symbol contract with Good Fortune. "It was as dark as the light, as turbid as clear, as slow and swift as death.

"..."

In the palace of the Phoenix Qilin Continent, Bai Long, who had gone to report to the Li family, had finally returned. Candle Jiu Yin anxiously asked, "How is it? Does Sect Master Li agree for us to go to Huo Shan to save someone?"

Bai Long's face showed helplessness as he bowed and said: "Sect Masters, Sect Leader Li said that Gu Xueluo is lively and fearless. He has secretly visited Huo Shan many times and is certain that she will step out sooner or later!"

Wang Qingchuan continued, "Then there's still the fifth hidden spirit. This is his first time in Huo Shan, and he's also a newly advanced sect's messenger. What happens if something goes wrong?"

The hidden spirit and Gu Xueluo had already been in Mount Huo for a day. As of now, they had not returned, so there was a high chance that they had some sort of secret. He had to go in as soon as possible and find out what the two of them were doing. Thinking up to this point, Zhu Jiuyin smiled helplessly and said in a clear voice, "Looks like Sect Leader Li will have to wait for them to come out. It would be better if we hurried to Huo Shan as soon as possible to find out the whereabouts of the two."

As he said this, the other envoys expressed their agreement. Thus, under the lead of Zhu Jiuyin, the few of them quickly ran towards Huo Shan.

After a long while, the hidden spirit had already practiced the first book completely a few times and memorized the contents of the secret manual well. At this moment, he realized the remaining black poison in his body was no longer present. His whole body felt relaxed and comfortable.

Suddenly, Gu Xueluo discovered that the strange characters on the cliff were disappearing bit by bit, as if they were being eroded. In just half an incense's time, the entire first volume of < The Profound Yellow Scripture > had completely disappeared, as if it had never appeared. Seeing this, the hidden spirit was even more surprised.

Gu Xueluo said, "Don't worry. Rumor has it that the < The Sky and Earth Profound and Yellow Scriptures > mental cultivation method overview and the other four scrolls are all human. Every time you practice one of them, this scroll of text will automatically disappear. This is the nature of this secret manual to prevent it from being used by bad people. "

Just like that, the hidden spirit had obtained the top secret manual in the six realms — — the first volume of the 'Black Yellow Scripture of the Heavens and Earth'. From then on, the top secret manual in his life had changed, becoming unfathomable and unpredictable.
