Mingye is eighteen years old this year, which means he still has two years to live. Life is like a clockwork with a set time. It will stop automatically after twenty years, exactly. Everyone is like this, it's called common sense.
But later he accidentally discovered that not everyone is controlled by twenty years of clockwork.
Some people can wind up.
It's a flimsy pseudo-science fiction with no technical content, just for everyone to watch and play with.
