Five-year-old cutie Xiaotuanzi accidentally activates an old watch left by her mom, only to connect with Su Wan from the apocalyptic world ten years ago—Su Wan, a genius geneticist framed as a "traitor" and hunted down. Xiaotuanzi uses her future memories to help Su Wan dodge traps, search for the purification source, and even teach her to build defense towers from scrap metal.

Turns out her very existence is the "variable" in her mom's fight against fate?
