The Art of Longevity was ranked second among the Four Great Mystical Books, which was enough to show its value.
If he cultivated this book to a high level, he might be able to live forever.
There were four great books in the world, and the first was the legendary War God Catalog.
Strictly speaking, the War God Catalog wasn't a book. It didn't have any written inheritance and was completely comprehended by Divine Decree. It was hidden in a place that was very difficult to reach.
It was said that this book talked about the most profound secrets of the universe, recording the secrets of heaven and earth and life since ancient times.
The history of this strange book could be traced back to ancient times, or even further back. It was impossible to trace the author of this book.
However, there was no doubt about the power of this book. It was the supreme martial arts metaphysics of ancient times. The other three great books in the world were all written from this book.
The Dao Sect's Art of Longevity was created by Guang Chengzi's Art of Watching the War God Catalog, and the highest level of the Demon Sect's Heavenly Demon Strategy, the Great Dao Heart Demon Seed Technique, was comprehended by the first generation of Evil Emperor Xie Xiong after he obtained a part of the records of the War God Catalog in an ancient tomb.
As for the Buddhist Sect's supreme martial arts sword code, it was created by the first generation founder of the Kind Sail Quiet House, Dini, after watching the Demon Sect's Heavenly Demon Strategy.
Therefore, if one were to trace the source, the last three of the Four Great Mystical Books in the world actually originated from the War God Catalog.
Among these three books, the strongest was undoubtedly the Art of Longevity from the ancient sage, Guang Chengzi, followed by the Heavenly Demon Strategy and the Sword Manual.
Song Shidao also yearned for the Four Great Books. Although the mental cultivation method passed down in his Southern Ridge Song Family was profound and unfathomable, it was still a distance away from the Four Great Books.
However, none of these four books were easy to obtain.
Although the Sky Demon Strategy and the sword manual were relatively easy to obtain, Song Shidao had never thought about them.
These two books were a little too biased towards the spiritual domain. If one practiced them properly, they might go crazy.
Moreover, cultivating these two martial arts could even change a person's temperament and even turn him into another person. This was something that Song Shidao could not accept.
Thus, he could only have designs on the Art of Longevity and the War God Catalog.
However, the difficulty of obtaining the War God Catalog was too high. The Art of Longevity was different. It was a book that Song Shidao could easily obtain.
According to Song Shidao's memory of this world, Shi Long had only possessed the Art of Longevity for two or three years. He wasn't sure when he had obtained it, but he knew that the Art of Longevity must be in Shi Long's hands now.
That was why Song Shidao came!
The Art of Longevity was something that Song Shidao was determined to get. He was sure that he could achieve immortality if he continued to cultivate the techniques in the Art.
The Art of Longevity was definitely not simple, and the War God Catalog was even more so.
This could be seen from the points required to exchange for the four great books in his system store.
The War God Catalog required millions of points, the Art of Longevity required hundreds of thousands of points, and the Sky Demon Strategy and Sword Manual could be exchanged for 20,000 to 30,000 points.
No matter which one it was, it was not something Song Shidao could afford.
Shi Long lived in the outskirts of the city, but Song Shidao came to the city. This was a trick he used to deceive the Yuwen family.
The Yuwen clan had spies all over the area, so it was impossible for them not to know that the Song clan's caravan had arrived near Yangzhou.
If Song Shidao didn't enter the city but went to the outskirts of the city, he would definitely attract the attention of the Yuwen clan, which might cause unnecessary trouble.
Therefore, Song Shidao entered the city first to confuse the Yuwen clan, making them think that he was in the city. When night fell, Song Shidao left the city in a night suit.
In a big city like Yangzhou, there were quite a few people who were running around in their night clothes. Song Shidao had met several of them in just a short while.
He shook off some malicious gazes and came to a remote place in the city. He directly jumped over the city wall that was nearly 100 feet high and jumped off the city wall.
Song Shidao silently made his way to the small courtyard where Shi Long lived.
The night was like water. It was a cold winter night. Song Shidao passed through the farmlands and forests and arrived at the place where Shi Long lived.
The environment here was very quiet and it was a good place to live in seclusion.
"After all, martial artists can't leave their daily lives and can't leave their meals. Otherwise, this stone dragon would definitely not live in seclusion in the suburbs of Yangzhou!”Song Shidao thought.
If a grandmaster did not need to eat, Shi Long would probably hide in a remote place to study his Art of Longevity!
It was precisely because he needed someone to provide him with his daily meals that this extremely cautious old grandmaster hid in the suburbs to study the Art of Longevity.
This also made it easier for others to snatch it.
