Briefly talking about this book and the theory of time and space, other works have been related to...
Other works related to the characters, story features, contact information, depressed modifications, etc., are all concentrated in "The Infinite Call of Rebirth of the Gods". Pen "Fun" Pavilion www.biquge.info
This book has the same content as the beginning of "The Infinite Call of the Divine Rebirth", and you can read the new book directly.
The reason why it occupies the first book independently is not only to attract readers by staggered classification, but also to commemorate the not-so-"bad" original as Su Le (the male protagonist).

By the way, the information about time travel that I have collected in the past should help you understand this book, but there are also some [spoilers].
A lot of the content in the front of this book is really difficult to understand, and it may be related to the chronological sequence, of course, it may also be unclear or changed to logical confusion......
In short, the follow-up will try to simplify the story as much as possible, and at the same time reduce the content involving [time travel], before Su Le traveled through time and space, it can basically be understood according to fate (fate).
【Time Travel Theory】
Theory A-Fate Fact (CircularCausation): Go back in time and try to save someone, but that person still inevitably dies, or even worse, your actions back in time are the cause of his death! This theory is reasonable.
Theory B-AlternateUniverse: Go to the past and save someone's life, and come back to find that nothing has changed! In "quantum theory", every possible probability creates another universe with that chance, so there are many "parallel universes".
Theory C-Success: There's a paradox in time travel – is it possible to go back in time and kill your great-grandfather (by mistake)? If he dies, you can't be born, and if you don't be born, you can't go back and kill him!! It may happen that after manslaughtering your great-grandfather, when you go back to your point in time, part of your memory has changed, and your great-grandfather has become a different person.
Theory D-ObserverEffect: Go back in time and succeed in changing history, but only the time traveler knows how it differs before and after it changes. In this case, when the traveler returns to the changed modern age, he may be a stranger, without any clues that would prove his previous existence in the world.

In this book, Su Le travels to ancient times to save Miko Homeko's tribe, Miko Kome later learns the origin of Su Le, so she asks the descendants of the clan to protect Su Le, and thousands of years later, Athena Mochizuki finds Su Le and carries out a protection mission.
There is another example, Su Le rescued Luo Zhi who was trapped in a day when he was a child, and when Luo Zhi grew up, he found Su Le before that, and went around in a circle, which is fate, which is similar to Theory A.
