Doomsday Harvest

Lizi Lizi, you are so disobedient!

As a science fiction novice, I don't know much about the professional terms used by the author in Qizi, but I read it without any hindrance. I don't know why, but I was inexplicably moved by the tenderness of the humanoid creatures at the end of the novel. But there are a few things I don't understand: First: From the perspective of Qizi, humanoid creatures are exiled to monitor the earth. So in the author's setting, are there other creatures that are exiled to monitor other planets? Will there be explanations later? Second: Did the old-fashioned radio choose to conceal the 1% hidden danger because it was overconfident or because it did not eliminate them all because of its feelings for the earth? Third: Will there be any scenes with old-fashioned radios and humanoid creatures later on? Fourth: There is no fourth! Come on, author!
