If Yan Junze couldn't come back after this Great Rewind, Xiang Er would still tell Zhang Xiaomo afterward, although the specifics were unclear, at least there was someone to pass the message.
To be honest, Yan Junze was also guessing whether his actions this time were reasonable, because in theory, on this timeline, he had already successfully launched the Great Rewind. He had rescued his past self from the Underground Space of Mountain Park and had survived safely up to the present.
If he could go back to attempt a rescue this time, but wasn't successful, wouldn't it be contradictory to the current sequence of events?
Of course, regarding the "Spacetime Fixed Point Insertion" feature in the Spacetime Atlas, Yan Junze only knew how to use it and had no understanding of the principles behind it.
