"Human civilization is overdue"
This is not a metaphor. A collection order from the universe sentenced human civilization to death: 4.1×10²²Tem's "time debt" must be paid off within a hundred years, and the entire race will be erased from existence.
I became the only bridge between humans and "the system." But repayment is just the beginning. The real test is the "gatekeeper test": entering a cage where time has stopped and spending seventy-two hours healing a civilization that has been divided in loneliness for eight hundred thousand years. Failure, and humans will become the next specimen in the Museum of the Universe.
"When I Became a Time Debt Body" - When the fate of an entire race is put on the gambling table, this is not a story about debt repayment, but about the ultimate trial of whether a civilization is qualified to continue to exist.
The countdown has begun.
