The Era of Inner Demons

My name is Lu Yan, a temporary agent at the Tianting Office in the Human World. My job is to wear a gas mask and recycle those sealed items that can make people go crazy in an abandoned factory polluted by the whispers of the past. I have no spiritual roots and no inheritance. All I have is a Taoist heart that has been planted with a "devil seed". That demon seed can make me swallow all pollution and become stronger - at the cost of the inner demons it will keep giving birth to. Colleagues call me "Mad Dog." The inner demon calls me "my true self". Until one day I swallowed the remaining whispers of an old god. The inner demon laughed. The old gods also laughed. They all said to me: Welcome home.
