I Rise from the Ashes

In the city of Iron Ash, the Fire Passing Ceremony is the only way for mortals to obtain the power of sparks. Even if they become Fire Suspensioners, 99% of them will have no effect. Each time the Spark Power is used, "dead ash" accumulates in the soul. When the ashes are piled up, people will turn into "soul extinguishers" who only appear at night. The nobles hold 1% of the special spark power and monopolize the method of removing dead ashes. When all the fire dwellers were afraid of death, Ren discovered a secret: he could spread the death ashes into mechanical parts. The price is that the parts will be scrapped due to sanding. However, a scavenger who can trade scrap metal for his life has become the most deadly variable in the entire system.
