Jiang Ran—the supreme genius from a parallel universe—transmigrated into the deceased girl's body, embarking on a series of brilliant moves that left her detractors eating humble pie. Her cousin knelt and begged for mercy, foreigners worshipped her in awe, and nations vied to recruit her; yet, Jiang Ran remained true to her original purpose, dedicating herself to the cause of her motherland.
