"I don't understand. Why do you keep saving me?"
"You had plenty of chances to kill me."
"If I said I had no choice, would you believe me?"
"I never expected the human heart to be as impossible to look at directly as the sun."

Hidden deep in the mountains since the end of the Zhou dynasty, an ancient village has guarded an evil seal for two thousand years.

It randomly selects sinners and sends them into worlds shaped by their deepest obsessions.
When her uncle, Ji Wuhen, vanishes under inexplicable circumstances, Ji Yu opens a black envelope that has mysteriously appeared in her home. From then on, she is trapped in the Abyss of Endless Obsessions, risking death at every turn as she completes various missions in these worlds. The secrets of her origins begin to reveal themselves, and she is drawn into a conspiracy from twenty years ago, uncovering the absurd truth behind it all...
