Time Lord

It is strongly recommended not to go backwards in time, as long as time speeds up and slows down, and at most a time pause is added. From a scientific perspective, pausing time would require infinite energy, which is no longer possible, let alone going backwards. From the fantasy side, generally super awesome worlds will not write about time reversal, and various logic bugs cannot be solved at all. For example, even if you go backwards in time locally, but there is material exchange between this part and the outside world, then your part must have affected the outside world.

Your updates are too few, I can't arrive for 10 minutes

I caught up with the last book, which was very good, but this one, honestly speaking, made me very tired after reading this type of book.
