One hundred years ago, modern warehousing supervisor Xu Zhaowei crashed her car and transmigrated into a white-haired old woman in Qingshi Village, with her life lamp having only a hundred days left. An upper immortal of the Qinglan Sect tested her granddaughter Xu Suining and found she had a heavenly spiritual root, but the granddaughter stubbornly refused to go alone, insisting her grandmother be tested together—who would have expected that she also possessed a heavenly spiritual root, only because her life wheel was shattered, she could only enter the sect in the identity of a mountain-guarding odd-job worker. Upon meeting the upper immortal, she knelt and kowtowed, bowing ninety degrees; yet turning around she hid her blade inside the account books, using modern accounting techniques to dismantle black contracts and check black accounts, forcing the high-and-mighty cultivators to spit out a price according to the rules. As the hundred days draw to a close, everyone waits for her to perish, but she breaks through her realm and becomes an immortal at the moment her life lamp extinguishes—her silver hair unchanged, immortal light initially appearing.
