On the one hand, he has to fight against the dangers in the dungeon, and on the other hand, he has to fight against the alienation in his body, struggling repeatedly on the edge of dissipation of humanity. The most poignant monologue in the book: "I desperately want to live, but the price of living is that I slowly no longer look like a human being." There is no deliberate attempt to show misery, all the pain is hidden in the details, the bleeding needle on the fingertip, the blurred vision, and the suffocating pain, bit by bit eating away at the lives of ordinary people, the feeling of powerlessness of knowing that the road ahead is an abyss but can only move forward makes people's hearts tighten, but they can't help but follow the protagonist to find hope for life.
