Lin Xiaohe, a corporate wage slave from the 21st century, works herself to death and transmigrates to a remote planet on the edge of the galaxy, where she becomes an abandoned three-year-old. After a garbage-collecting robot picks her up, she struggles to survive with her modern knowledge (?) and adorable looks (√). One day, the empire's youngest marshal, Xiao Hanyuan, known as the “Sword of the Empire” for his cold-bloodedness, discovers the toddler while pursuing space pirates. She's munching on a nutrition paste in a garbage dump and has cobbled together a “perpetual motion machine” from scrap metal (which is actually a fan). Even more shocking, a DNA match reveals that she's the empire's little princess, missing for five years!
