The author used to reply in the comments, but it seems that everyone did not look carefully at the author's reply. Here, the author solemnly reiterates: there is no deviation from the topic, and there is always only one main line: the trash can.

If the reader reads the text carefully, he should also see the foreshadowing set by the author. The world in the novel has a relationship with the trash can. In the author's setting, the trash can will be upgraded, from only teleporting items to teleporting images and finally being able to teleport people, and the key to upgrading is in the world of those protagonists. This is set by the author himself.

Above, hereby declared.
