Turn to Ashes in Nine Days

The sky has nine days, the eighth day turns to ashes, and the sun's ashes fall all over the world. Mortals avoid ashes and are born, while monks take ashes into their bodies and light the furnace of life. Those who have a pure hearth fire embark on spiritual practice, while those whose hearth fire is out of control will burn their hearts and become demons. Lu Jin, a young man who guards the Well of Huiwu, was born with a cold body and his life furnace failed to burn. He was regarded as a cold-blooded person. Until one day, the ash purification well turned black, and those who drank the water from the well looked gray. Lu Jin was pulled by the ancient artifacts underground and fell into the black well, where he saw an unburned sun bone. From then on, others took ashes to make fire, while he took ashes to make frost. And the last sun is getting dark.
