The continent of Northrend regards golems as cold killing tools. Only the 15-year-old mechanical dwarf Ding Ding firmly believes that golems can have a warm heart.
After awakening the talent of "Gear Resonance", he used scrap gears to piece together the first small iron that could wipe tears, and activated the "Gears and Hearts" system.
When human parents tried to send their children to his golem kindergarten, Dingding designed emotional gears and taught the golems to use steam to cook porridge and use the gears to sing to sleep.
However, war puppets created by radical puppet masters swept the town. Ding Ding commanded the puppets in the kindergarten to form a steam barrier and awaken the protective instinct of the war machine with warm emotions.
"They are not weapons," Ding Ding showed the image of the golem blocking the child from falling objects at the race council, "they are partners."
When the "Heart of Gears" shines brightly in the parliament hall, the mainland ushered in the dawn of the dance of machinery and soul.
