Shake the Sky and Cross the Earth, Sing Forever

Have you ever wondered what lies beyond Earth, and beyond? I don't want to just stay in this small place for the rest of my life. It seems to me that this place is very small. I want to see other aspects of the universe. . . . Gu Yang thought so too, but he didn't know that this idea was closely related to his country a thousand years ago. . . If your future is strong, strong enough to change your weak self in the past, then how does your strong future self become stronger? This is a very complicated question, but it is not as simple as you think. This is not an endless loop. There may be secrets that we cannot understand that are trying to change our cognition! Gu Yang's cause and effect originated thousands of years ago and will be unraveled bit by bit in the future. Perhaps he will be able to see clearly what his own path is and what his true nature is in his future journey! If possible, I would like to go and see it with him. . .
