The old man suddenly found that he had a clock in his mind.
He spent a second trying to figure out whether the clock had been there all along, to no avail;
It took him another minute to think and come to a conclusion: this clock shows the countdown to his lifespan.
Alas, people have to end up in the loess after all, and besides, I am quite old. Maybe this clock never affected his life from beginning to end; or maybe it was a gift:
God gave him a special opportunity, allowing him to create the most perfect "last moment" for himself within 85 days.
Then, there is only one thing to do next:
Find the most perfect "self".
