The Chinese battle suit, also known as the Heavenly Armor.
This ancient armor forging technique originated in the renaissance period of Europe, initially developed by alchemists to create metal puppets with powerful protective capabilities to safeguard their masters' frail bodies.
Around three hundred years ago, alchemists from Nederland disseminated this technology into the Fusang territory in the Far East, where it was improved by monks of Sensoji Temple, renowned for their craftsmanship skills, creating the "Black Cloud Armor" powered by steam engines.
Later, Fusang Ronin warriors invaded the borders of Ming Country, further spreading the technology of the Black Cloud Armor into Ming Country. After being refined by master craftsmen from the Mohist school, it evolved into the "Heavenly Armor," a divine artifact for the nation.
