This is a world completely "captive" by gods. At the moment of birth, the "Mark of God" will appear on everyone's forehead, which determines their career, status and upper limit in life. Believers worship the gods devoutly, thinking that it is salvation, but they do not know that the gods are absorbing human spirituality through their marks. Fengxu was born in the most humble "slaughterhouse" area, with only a blood mark on his forehead representing blasphemy. He spent his whole life killing pigs in the temple's slaughterhouse, until one day he accidentally swallowed a fragment of the god's fallen finger. From then on, his butcher knife no longer pointed at livestock.
