"If you had to personally 'kill' yourself in a parallel universe every year in order to preserve the survival of this world, what would you choose?"
Starting in 6025, Earth will gain one extra "leap second" every year. In this 1 second, 80 million parallel universes will be born simultaneously around the world, crowded together like bubbles.
The government has established a "backup bureau" and the rules are simple:
Every time a "leap second year" passes, you must kill yourself in any parallel universe within 24 hours, otherwise both universes will collapse.
The "self" who is killed is called the "backup body". The killing process is legal, tax-free, and points are awarded.
Points can be exchanged for real estate, further education, or even resurrect relatives.
As a result, "How to kill yourself gracefully" became the most popular paid knowledge course in 6026.
