**Chapter 1562: Rune Classification, Power of the Other Shore**
Lin Moyu quickly digested the knowledge brought by "Fuyu." In the book "Fuyu," runes are divided into five categories.
The first is the most common basic type, which is the foundation of all runes and the most numerous. For example, using runes to outline a certain spell and casting it with the help of runes. The spell here does not necessarily have to be one you master; as long as you understand the principle of the spell, you can cast someone else's spell. However, without the corresponding laws, the power of the spell will be greatly reduced or have form without spirit.
The second type is the law runes, which are a level higher than the spell runes. They represent a certain law, and when cultivated deeply, they can even manifest the law. Manifesting the law is useless to those at the Other Shore realm, but it is very useful to cultivators below the God Sovereign. If there is a manifested law as a reference, the speed of comprehending the law can be multiplied.
The third type is the rule runes, which can be used to cast rules. Lin Moyu encountered the term "rule" for the first time and had never heard of it before. "What is a rule?" In "Fuyu," the level defined by rule runes is very high, even higher than law runes, indicating that rules are very powerful.
The fourth type is the combination runes. The previous three types of runes are all single runes. Combination runes combine various runes for use, either to enhance the power of runes or to form rune arrays. Once combination runes are mastered, the role of runes is infinitely expanded.
The fifth type is the creation runes! Among the five types of runes, this type is the highest level and the most difficult. "Fuyu" does not provide a detailed explanation, only a definition. Lin Moyu guessed that the soul fire rune should belong to the creation runes. By using a large amount of soul fire, it grants wisdom to living beings. Isn't this a form of creation? But this is not true creation. In Lin Moyu's understanding, a true soul fire rune does not need external soul fire to directly grant wisdom to living beings. Elder Xu's soul fire rune should have taken the wrong path.
After a moment, Lin Moyu slowly opened his eyes. The information on the first page had been completely digested, and Lin Moyu had a systematic understanding of runes. The runes recorded in "Fuyu" are actually all low-level runes. The truly high-level runes are not recorded inside. Combining Elder Xu's words, Lin Moyu knew that high-level runes could only be accessed at the peak of the God Sovereign realm.
At this time, the palace was getting closer to the divine city, flying around it. It was estimated that in a moment, they would truly reach the divine city. Lin Moyu calculated that it would take about a day from their departure to reach the divine city. This was because the palace was fast enough; if it were an ordinary battleship, the time would be even longer. Not setting up a direct teleportation array to the divine city had its own considerations. This way, if enemies wanted to attack the divine city, they would have to fly over honestly. It was absolutely impossible to launch a surprise attack through teleportation.
After digesting the knowledge of runes, Lin Moyu couldn't help but have a few questions. Just as he was about to ask, Saint Hao spoke first, "Lin Xiaoyou, now that you have some understanding of runes, tell us your thoughts."
Lin Moyu responded, "The way of runes is profound and vast. I have only scratched the surface and have no real insights."
Elder Xu looked at Lin Moyu as if he were a rare treasure but pretended to be deep, "You have a strong understanding of runes and are very suitable for this path. In your future cultivation, you should devote some energy to runes."
"Understood," Lin Moyu naturally understood this principle.
Saint Hao said, "If you have any questions about runes, you can ask now."
Lin Moyu had been waiting for this and immediately asked, "Seniors, I want to ask, in 'Fuyu,' runes are divided into five categories, one of which is rules. I don't understand what rules are."
Saint Wu smiled and said to Elder Xu, "You answer this question."
Elder Xu did not refuse, "To understand rules, you must first understand what laws and spells are. Spells follow laws, and spells have varying strengths and different effects, but they cannot surpass the limits of laws."
"However, rules transcend the limits of laws. They are a higher level of existence. They can ignore laws, change laws, and even destroy laws."
From Elder Xu's words, Lin Moyu felt the terror of rules. Ignoring laws, changing laws, and even destroying laws. What a terrifying power. At the same time, he thought, if such power exists, what is the point of comprehending and cultivating laws?
Saint Hao smiled and said, "Don't overthink it. Rules are powerful, but they are not omnipotent. They require realm and one's own strength."
"To put it simply, rules are higher than laws and based on laws. If you haven't comprehended your own laws to the extreme, you can't evolve rules from them."
Saint Wu and Elder Xu patiently explained to Lin Moyu what rules are. Simply put, rules are a higher form of laws and spells. The power of rules is something that only those at the Other Shore realm can control. They did not explain the specific process because Lin Moyu was far from that level. Even if his soul had reached it, it was useless.
Saint Hao pointed to a distant galaxy and said, "That is an uninhabited galaxy. It operates according to established rules, with countless laws intertwined, maintaining the galaxy in an orderly manner."
"Now, I will make some changes to it!"
Saint Hao raised his hand and casually grabbed at the uninhabited galaxy. The galaxy trembled, and all the stars began to rotate in reverse. The entire galaxy's trajectory changed. Lin Moyu was shocked. Destroying a galaxy is not difficult; even he could easily do it. But to reverse the operation of an entire galaxy without harming any stars is as difficult as climbing to the sky. This is not something that can be done with sheer power; it requires truly changing the internal rules.
Lin Moyu felt the changes in the galaxy and murmured, "Using the power of rules to forcibly change the established rules of the great world, changing part of the laws."
Saint Hao smiled slightly and withdrew his power. The galaxy trembled again, and the stars that were rotating in reverse slowly stopped and then began to return to their original operation.
Saint Hao said, "The great world has established rules. On a large scale, I can only change a part of it, and it cannot last long. This is just the simplest application of rules. Using the power of rules can accomplish some incredible things."
Elder Lin said, "It is said that in ancient times, powerful beings could combine hundreds of galaxies and use them as weapons."
"They could also reverse-refine laws, instantly refining thousands of stars into magical treasures."
"Rules are really a good thing, but they are too difficult."
