Thirty days of life from the start, with only 48 hours of oxygen left...
Shi Xian, a 12-year-old girl who skipped grades, wanders into a weightless space graveyard and is forced to bind herself to the “Time Loan Shark System”:
“Every 10 minutes you borrow, you must teach a stranger one elementary-school math olympiad problem on the spot, or twice that much will be deducted from your lifespan!”
Coffins float around like kites, and mechanisms use “chickens and rabbits in a cage” as their key.
The interest on romance is even more outrageous: holding hands for one minute means paying back 60 minutes of life, so the heroine puts a stop to romance before it can even begin.
To stay alive, she livestreams “remote tutoring,” with elementary school students across the country lining up to solve problems and help pay off her debt:
“Thanks, Big Sis! I know how to do this one!”
A big-shot archaeologist is forced to be her study buddy, working through A Guide to the College Entrance Exam: Five Years of Past Papers, Three Years of Practice.
From negative 30 days to eternal life, she turns tomb-raiding instances into huge tutoring sessions,
and grows into the short-lived darling of the whole group.
[Highlights]
① A fresh “time loan shark” golden finger: a lifespan countdown meets the absurd contrast of math olympiad problems, enough to make you laugh your head off!
② Weightless tomb passages, livestream comments, and remote tutoring: three settings blended together, perfect for low-effort short-video adaptations!
③ No CP, but everyone dotes on her. The emotional payoff is maxed out, with no messy romance drama!
Knowledge is the ultimate key to immortality!
