Three-and-a-half-year-old Yun Qiaoqiao is the most worrisome disciple of the Zhutian Sect's Artifact Refining Peak—blowing up smelting furnaces, lifting roofs, and pulling up town-hall banners, disciples across the sect run the moment they see her. Her master, Que Wuya, was blown underground by her and is missing, leaving behind only the phrase "Accounts Settled" and an opening-mountain hammer. To retrieve the sole Taichu Profound Iron of the ninth grade for her master, Qiaoqiao hoists a hammer taller than herself, carries Xiao Xiu the little iron-eating beast, and blasts all the way into the Myriad Furnace Abyss. The whole sect says the Artifact Refining Peak has produced a living ancestor, but Qiaoqiao only wants to find her master back—Master, just wait for me; Qiaoqiao is coming to save you!
