My name is Gu Changsheng, a mortal who doesn't even have spiritual roots. The village where I live has worshiped a god who calls himself "Mercy" for generations. We offer the best sacrifices and the most devout faith, but what we get in return are disasters and poverty year after year. Until that day, my childhood sweetheart was chosen as the "God's Wife" and would be thrown into the furnace to be turned into a touch of gold paint for the statue of the God. I suddenly realized that this god is not here to save all sentient beings, but to suck our bone marrow! They said that mortals cannot defy God, so I used my mortal body to ignite my longevity and raise my sword to the sky. They laughed at me for just a piece of mortal iron in my hand, so I used this mortal iron to cut off his eternal incense! With that sword, I died, but it didn't seem like I was dead. When I opened my eyes again, I found that I was the only mortal in this world - a mortal without a "god".
