[Comprehensive] IF masters have retired

The doctor is still alive (although not sure if he is still alive), there are two big and small tomatoes at home (Da Vinci dear! Double happiness), Kadoc and other seven people are under guard (should not appear), only Lixiang retire alone.

(The age of 17 is just a setting. It stands to reason that Lixiang is almost 20 at this time, but don't care about these details!)
