The sky of the abandoned capital collapsed, and all the people fell into eternal night. Yunxiu used blood as a guide to recast the bones of the sky against fate. In order to protect his lifeline, Shen Zhihui arbitrarily determined all opportunities and burned all his own karma. When theocratic institutions kill heretics in the name of "order", and when the mechanical gods devour the last bit of humanity, one of them is a crazy sky-caster, and the other is a silent god-killer. In the ruins intertwined with steel bars and blood mist, they ask the law of heaven with their lives - if the sky is dead, who is worthy of restarting it? They don't seek to become gods, they only seek to be human beings and be able to look up at the stars.
