After N consecutive all-nighters lasting two days and one night, Qin Ge went to the supermarket to buy instant noodles, but unexpectedly discovered a set of numbers in front of his eyes. They included year, month, day, and time, and they were constantly counting down.

And his lifespan value was—3 days, 7 hours, 21 minutes, and 19 seconds!
