What is the underworld like? It seems to be different from what I knew when I was alive. My name is Han Ke, and I am a Mengpo. I lost all my memory during my lifetime, and was picked up by Ksitigarbha Bodhisattva after my death. The people in Hell are very nice, especially Jiuwan, who always tolerates and protects me infinitely. As memories are retrieved bit by bit, it turns out that everything has a cause and effect. What is the truth? What is your sincerity?
