"The key to the great way?" Xu Changqing was stunned for a moment when he heard this. He originally asked for it just to deliberately make things difficult for the fossil old man to avoid him continuing to explore whether he had mastered the complete Guigu Way. He did not think that the fossil old man would answer his inquiry. Although the names are different, it can be judged from the meaning of the name that it is related to the great way of heaven and earth. According to Xu Changqing's previous judgment, the Hundred-character Heart Certificate is probably a fragment of the creation jade book of Hongjun's natal magic weapon, and Hongjun's ultimately has the same way as the world, so the relationship between the two overlaps.

"It seems that the Tao of Guigu is really related to the Hongjun family!" Xu Changqing became more and more sure of some of his previous hypothetical guesses about the Tao of Guigu, and muttered to himself.

The fossil old man didn't know what Xu Changqing was thinking. Instead, he was very satisfied with Xu Changqing's expression when he heard this and continued: "I don't know much about the specific situation of the Hundred-character Heart Book. I just knew from some of the book scripts that passed down from Guigu that this thing was a thing passed down from Guigu, and it was also the key to unlocking the complete Guigu Way in the book scripts. However, this thing has disappeared from the world since Zou Yan. I entered the Kunlun Three Realms to find this thing."

Xu Changqing smiled and said in a sceptical tone: "Senior doing this seems to be a bit like looking for a needle in a haystack. Did you find all over the world? You are so sure that the hundred-character heart certificate is no longer in the world, but in the three realms of Kunlun."

The fossil old man smiled, and his incarnation's eyes showed a ray of light, which fell on Xu Changqing, saying, "I have indeed not traveled all over the world, and there is no need to search like this. A method has been passed down from Guigu lineage. He can sense the existence of the Hundred Character Heart Certificate and the people or things who have been in contact with Hundred Character Heart Certificate before."

"So that's it." Xu Changqing showed a sudden look and said, "That's why you appeared in front of me so suddenly. Then he deliberately guided me to become interested in the Guigu Qi Practice's calligraphy, and influenced fellow Taoist Xuanweizi to present the calligraphy to me and let me read it, and then see if I can find out the secrets in the calligraphy."

"Not bad!" The fossil old man admitted readily and said proudly: "The effect is very good, isn't it?"

"Senior is so sure that I can completely unravel the Guigu Way hidden in the book in a short period of time?" Xu Changqing did not hide it anymore, and simply admitted from the side that he had mastered the complete Guigu Way.

"You are not the first successor of the Nine-Rank Line I have ever seen," said the fossil old man with a slightly envious tone: "Whether it is your disciple Huangshan or your ancestor Xuan Qingsu, they all have a magical power that can master and comprehend strange Taoism in a short time. You are also an orthodox descendant of the Nine-Rank Line, and I think it is not worse than them."

Xu Changqing was slightly stunned when he heard this and said in a deep voice: "Senior, even Xuan Qingsu knows it. It seems that even though he is in the mortal world, he still knows the situation of the three realms of Kunlun!"

"The mortal world is also part of the inner spirit mountain, and you are not the only one who can see the value of the mortal world." The fossil old man said meaningfully: "However, they all have a low opinion of the value of the mortal world, including me back then. Only you, and only you have a qingchu and correct understanding of the value of the mortal world. To be honest, I admire your point."

"Give me a prize, too much!" Xu Changqing pretended to be modest, and then took the initiative to put the topic on the right path and said, "Since I am so sure that I have a hundred-character heart certificate, how should I take it from me?"

"Haha! Misunderstanding! Misunderstanding!" The fossil old man was slightly stunned for a moment, then laughed, repeatedly saying misunderstandings, then curled his smile and said sincerely: "It seems that my actions have caused fellow Taoists to misunderstand! I am not interested in the Hundred-character Heart Certificate. Although this thing is magical, it is not something I can own. To be honest, I saw the Hundred-character Heart Certificate Shortly after I arrived at the Three Realms of Kunlun, and copied all the words."

As he spoke, he saw the fossil old man raising his hand in the air to stimulate the thin spiritual energy around him to write lines of text. After reading these words, Xu Changqing was stunned because these words were indeed all strange words on the Hundred Character Heart Book, but the content was a little wrong, and the number was much larger, and there were some words. Xu Changqing had never seen them on his Hundred Character Heart Book, and it felt like a forged thing.

Just when Xu Changqing was puzzled, the fossil old man had already written all the complete rubbings. At this time, all the magical words floating in the air were printed into Xu Changqing's eyes. Almost at the same time, the Golden Immortal body, far away in the chaotic void, felt a slight change in the heart certificate that was together with the Earth Immortal God Monument, and the words on the surface of the heart certificate became more and more, and all the words written by the fossil old man appeared on it.

There are not many words in the whole article, and the movement caused by the Hundred-character Heart Certificate has subsided as the text is copied. Xu Changqing no longer doubts whether the fossil old man has seen the Hundred-character Heart Certificate, but the difference in the text makes him feel other suspicious and asks: "Where did you get the Hundred-character Heart Certificate from?"

"Immortal Palace and Yuxu Palace." The fossil old man didn't want to create any more misunderstandings, so he answered truthfully and concisely.

"Immortal Palace, Yuxu Palace?" Xu Changqing was stunned, then a hint of surprise flashed, and said, "There are two hundred-character heart certificates?"

"You wouldn't think that the Hundred-character heart certificate was only one like me back then, did you?" The fossil old man quickly understood why Xu Changqing had this question, gently stroked his beard, and said, "I don't know how many Hundred-character heart certificates are. I'm afraid even the head of the Yuxu Palace and the Lord of the Immortal Palace would not know the number. If I hadn't happened unexpectedly back then, maybe they wouldn't have had a Hundred-character heart certificate in each other's hands. If I was not guessing correctly, the Hundred-character heart certificate in your hand, Fellow Daoist, probably did not come from the Immortal Palace and the Yuxu Palace?"

Xu Changqing did not answer the fossil old man's words, but asked in confusion: "Since this thing is so mysterious, why can the seniors get from the Lord of Yuxu Palace and the Immortal Palace..."

Before he could finish his question, the fossil old man replied first: "Because I promised to help them destroy the Taishang Qingjingtian Dynasty."

Xu Changqing frowned slightly and said, "Is the Taishang Qingjingtian Dynasty that was already powerful enough to be the status of the Wannian Immortal Sect?"

"Although the Taishang Qingjing Heavenly Dynasty is powerful, it will not constitute a wēixié for them." The fossil old man shook his head and said, "What they are really worried about is the fate of Emperor Haotian, the fortune of the Immortal Dynasty and the creation map, which will have unpredictable consequences."

Xu Changqing chuckled and said, "If what I expected was, it should be that the senior should have contacted the Immortal Palace and the Yuxu Palace. It was also the senior who took the initiative to reveal that Emperor Haotian was their potential wēixié, because the senior was facing a life-and-death choice at that time, right?"

Although Xu Changqing did not say it bluntly, its hidden meaning was enough to allow the fossil old man to infer its true meaning. In response, the fossil old man did not hide it and said, "It seems that you have really mastered the complete Guigu Way, otherwise you would not have been able to infer my situation so easily."

"I'm just a little confused." Xu Changqing still did not admit the fossil old man's judgment, and then shifted the topic back to him, saying: "Since my senior has seen the Hundred-character Heart Certificate and there are two more pieces, why can't the senior unlock the complete Guigu Way hidden in the book's simplified script?"

"I have been puzzled for thousands of years." The fossil old man sighed a little emotion: "If this hundred-character heart certificate is false, but I have been toggling this thing for thousands of years, and have unlocked some methods of the Guigu Way, but that's all." As he said that, he looked at Xu Changqing and said: "It seems that the problem should be on the hundred-character heart certificate you have on your body. Your piece is the key to unlocking the Guigu Way in this book."

Xu Changqing did not show any unexpected expression. He had already thought of this at the moment of asking the question, but he was puzzled. Indeed, since the fossil old man was able to find the accuracy of the hundred-character heart certificate in such a large place as Kunlun Three Realms, why can't he find the hundred-character heart certificate in Xu Changqing's hand in the secular world? Now I think there are only two possibilities. One is that the hundred-character heart certificate at that time was no longer in the secular world. It fell into the human world later, so naturally it was impossible to find this thing in the secular world. The other is that the hundred-character heart certificate has some special features compared to other hundred-character heart certificates, and even if it is used, it cannot be found where it is.

Thinking of this, Xu Changqing, who had originally liked to think randomly, could not help but associate things with the Hundred-character Heart Certificate of the Immortal Palace, his mother was probably Kong Daomiao, the Hundred-character Heart Certificate of the Immortal Palace, and the Hundred-character Heart Certificate of the mother, which was inherited by the ancestral objects of the Zhou family. He felt that the reincarnation of Kong Daomiao as his mother seemed to be more complicated than his previous guesses, which made him feel an impulse to rush to the Immortal Palace to meet Kong Daomiao immediately.

"Actually, there is no conflict between you and me, but the interests are the same." The fossil old man did not see Xu Changqing pondering, but persuaded himself: "Fellow Daoist Xu, you just want to establish a dynasty. Since you already have such an understanding of the Tao of Guigu, you should also be very qingchu. I also need to use this dynasty to practice the Tao of Guigu. Why don't you cooperate with me?"

"Without you, senior, I can still establish a dynasty in this mortal world." Xu Changqing felt a little unhappy at the fossil old man's interruption of his meditation, and his tone became slightly tougher, saying, "Since that's the case, why should I do this to cooperate with you, senior?"

"But if there is an old man, things will become easier and there will be less trouble." The fossil old man's tone also became a little wēixié, and he said, "I think Fellow Daoist Xu would not want his decision to spread throughout the three realms of Kunlun, let everyone know, right?"

"Senior, are you me?" Xu Changqing raised his eyebrows and said coldly.

The fossil old man pointed at it without showing any weakness: "No, I am just talking about a fact."
