Huosheng resigned from his city job and returned to the mountain village, wanting to make the iron-flower casting, which had been extinguished for three years, light up again. Grandfather Tie Xinghe initially thought no one would watch and it wouldn't make money, but Liuxu helped him look up materials and record folklore, and the villagers also gradually joined in repairing the furnace. After the iron furnace was reignited, it was once again extinguished by a heavy rain; Huosheng still insisted on re-burning, continuously practicing under grandfather's guidance. As performances and dissemination brought attention, the village re-saw the value of this old craft. In the end, everyone established an iron-flower casting cooperative, molten iron rushed into the night sky once again, fire-trees and silver-flowers lit up the village, and also gave the craft a new inheritance.
