To be fair, the Dragon King doesn't care much about all technologies and changes, and is even somewhat resistant. He can ride a horse or climb stairs, write letters or pay with real money, and it has remained unchanged for ten thousand years.

Now pa, the setting is the ending of the Black Dragon Lady, and the two of them lived until 2023.
Intention: The Dragon King should also keep pace with the times
