Lin Xiaochuan, a loser college student, accidentally awakens the "Instant Kill System". He thought he could turn his life around, but discovers a fatal bug—he must stay within 10 meters of his sister Lin Wanwan to activate the system! However, his seemingly gentle and soft office worker sister is actually a thousand-year-old hidden immortal cultivator, capable of destroying a villain’s sect with a wave of her hand. To activate the system, Lin Xiaochuan is forced to start his "sister-sticking daily life": he pretends to be a delivery guy to follow her to work, ruins her blind dates by exposing scumbags, and even tags along to immortal cultivation secret realms to snatch opportunities… But when villains come to take his sister’s "immortal bone", Lin Xiaochuan realizes that his system is not a cheat at all—his sister had already bound him with a wisp of her soul long ago. The so-called "instant kill" is just her gentle way of covering for him. And the feelings they’ve hidden for years gradually surface amid repeated crises…
