For the sake of Julian's Sid Auction House, Watson had no choice but to block all the actions at the scene in such a surprising way that ordinary people could not understand.

In the end, Watson found the most obvious logo of a high-end imitation, which came from the fact that Leonardo da Vinci was a left-handed man.
As for some famous paintings of Leonardo da Vinci, if you observed carefully, you would find a common rule that the theme of the whole painting was always left.
