Who I am? Why are you reborn in despair again and again and lose everything again and again? Lin Mo, a visitor from another world who carries a blood feud, is involved in a cruel "game" controlled by a higher being. The rusted city, the lightless realm... Every world is a cage, and every breath comes with a price. When survival means struggle, when the truth is covered up layer by layer, when the beloved turns into soul fragments with different faces, what is the meaning of his existence? Will you sink into fate, or will you, in the midst of endless rebirth, use your mortal body to challenge the "gods" who control everything and never surrender?
