"Yes. Xiao Yu's head.

"Some of these laws exist independently, or are based on some inherent unique incarnation of the Three Realms, while others are not, breaking through the limitations of the Three Realms and existing in the wider universe. ”

Xiao Yu's eyebrows raised slightly, "Like time?"

"Not bad," Jiuyang's voice sounded in the void, "Time is one of them. Time not only guides the Three Realms, but it is not within the boundaries of the Three Realms, and in different states, the existence of time is also different, which is the infinite possibility of the existence of time. ”

Xiao Yu looked at Jiuyang thoughtfully, "What states might affect time?"

"Space, speed, quality...... In fact, time is just a certain cognition of the universe, and under this simplified cognition, people can try to understand many things, and people try to quantify it as a specific existence, in fact, it can be done, but in the universe, the existence of time is not limited by people's understanding. ”

Xiao Yu groaned, "In other words, we can only use time, but we can't really control time. ”

Jiuyang smiled slightly, "That's not necessarily." ”

Xiao Yu's spirit froze, "Please make it clear to the master." ”

Jiuyang said indifferently, "It may be a little complicated to say, but if it is short, it is also very simple, that is, when you reach the critical point of time in a certain form, you can try to master time." ”

Xiao Yu frowned, "For example"

With a slight tap of Jiuyang's fingertips, Xiao Yu suddenly felt that the divine shadow moved, and he actually ran between the stars at an infinitely fast speed, the light and shadow in front of him changed, and the light released by the nebula was bright and beautiful, when his speed reached an almost extreme speed, everything around him suddenly became slow, and even the light released by the nebula became faintly captureable.

Xiao Yu was stunned for a moment, suddenly the world changed, and he had stood in place again, and the sword had almost stayed in its original position, without any change, as if he had never experienced anything.

"When the speed reaches a certain height, time becomes slow, even controllable with the naked eye, which is why you control time slowly. ”

Xiao Yu had never had such a fast speed, although he heard Jiuyang's explanation in his ears, he was still stunned in his heart, recalling everything he had just experienced, and said for a long time, "Is this the speed of the limit?" ”

Jiuyang smiled, and the question Xiao Yu asked was the point he wanted to explain, "Naturally not." There may be a limit to the speed of the universe, but even if you cultivate to the god, or even beyond the realm of the god, you may not be able to understand and perceive it. To be precise, there is a certain limit to each world, for example, within the Three Realms, the limit of time is the speed of light. ”

"The speed of light ......"

"Although you can travel between different spaces, with the help of the laws of space, although in the strict sense, time and space cannot be separated, but you can reach another space in the shortest time, not because your speed has broken through the limit. Within the Three Realms, light is the limit of speed, and if you can reach the speed of light, then everything will stand still, and the dimensions you can see will become different from before, in which case, you can control time to some extent. ”

Xiao Yu frowned and said, "But the Eye of Nothingness can devour light, if the speed of light is extreme, then how does the Eye of Nothingness manage to devour light?"

In Jiuyang's calm expression, there was a quiet sigh, "That's because the Demon Venerable has mastered stronger power and has already reached the limit of speed, so he can guide me to the world millions of years ago." ”

Xiao Yu was stunned for a moment, and then he realized that in the limit of Jiuyang's operation, he could barely capture the movement of light, but there was still a long way to go if he wanted to reach the speed of light. In other words, the reason why Jiuyang is standing here is not his own strength, but the power of the Demon Venerable.

"In this way, with your master's cultivation, you can't go back to the past, can you?"

Jiuyang's expression was solemn, and he said slowly, "Running is the avenue of the universe, since time has passed, how difficult it is to go back to the past, even if I can do it, it is only in another way." ”

Xiao Yu was curious, "In what way?"

Jiuyang turned his head to look at Xiao Yu, "Everything you see now is one of those ways. ”

Xiao Yu became more and more stunned, what he saw now was just a picture.

Jiuyang's voice sounded in a deep voice, "Time is the law of the universe, no matter what realm you cultivate, the right way is to conform to the law of time, and going back to the past or the future is fundamentally contrary to the Great Dao of the Universe." ”

Xiao Yu's eyebrows furrowed deeply, it wasn't that he couldn't understand Jiuyang's words, but he didn't know why Jiuyang said this, and what was the relationship between all this and what he had just said.

However, Jiuyang quickly gave an explanation, "So it is okay to go back to the past, but it is extremely difficult to do it without having any impact on the past, so the correct and safe choice is not to return to the past in the main line, but to return to a world parallel to the main line." ”

Xiao Yu's eyes showed a clear look of confusion, for what Jiuyang said now, he couldn't understand it at all, what is the main line, and what is parallel?

"Old man, the more I listen, the more confused I become. ”

Jiuyang smiled slightly, "If you tell me that you completely understood, I would be surprised, but it is easy to understand when you said it, for example, when you were in the God Realm that day, you did not choose to approve of the Demon Venerable's practice, but insisted on staying in the God Realm, so you shouldn't be standing here now." ”

Xiao Yu didn't know what Jiuyang wanted to say, but he still bowed his head and said, "Not bad." ”

With a slight touch of Jiuyang's fingertips, a ray of divine light transformed, spreading to the endless distance, on this ray of divine light, countless pictures were conjured, and a world was constructed, which did not look like a false, but extremely real, as if there was another world, and in this world, there was also a him.

"This is the parallel world, in the world you are in now, your consciousness is the subject, but there are still countless parallel worlds in the universe, and in those worlds, there are also countless possibilities. ”

Xiao Yu suddenly woke up, these were not unexperienced before, when he first came to devour the cultivation of the Big Dipper Heavenly Source, he had come to the Demon Realm, at that time he had been puzzled, and now he finally understood that it was because of the parallel time and space caused by the "Way of the Universe".

"Old man, do you mean that the world I am in now is also a parallel world?"

Jiuyang smiled, "Exactly." ”
