Silk Book of Old Memories

There is a strange glimmer in the world called Yisi, which comes from the regrets, guilt and obsessions that people can't let go of. Yisi hidden in the depths of the earth, to? An independent fantasy prison opens a trial, from Zero to? No. 1 Examination room, which accommodates all those who are burdened with the past and have shackles on their hearts. Each prison re-enacts the most painful and missed yesterday of the prisoner's life. The illusion breeds obsession and phantoms as prison guards. Only by facing the darkness and tenderness hidden in the heart can one break the shackles of silver and get out of the cycle of reincarnation. All the "people" who come here are by no means good, and only those who can't let go of their obsessions will come here.
