Large chunks of irrelevant explanations account for almost two-thirds of the book, and the plots that can really be seen are interspersed among these contents, which makes people sleepy and thankless. To quote Cat's Face: A false, big and empty feeling comes to my face. ..... Where is the author who wrote the tomb of Wu? It's getting worse. I remember the protagonist once said, "The people I care about must let you live."
Probably means the same thing. A few days before the protagonist returns to the end of the world, in order to prevent his parents and sisters from dying like previous lives. He called his sister back and told several close friends. What is the reason? It's totally untenable. What? The end of the world? Don't tease me, normal people's first reaction should be like this, but they won't believe it anyway. The protagonist also knows that they won't believe it, so he takes it with him, just for peace of mind.
