In Chinese mythology there were ten suns that would cross the sky one by one. When they showed up all at once one day, scorching the earth, King Yao asked Hou Yi to deal with them. He tried to reason with the suns then threaten them with his bow but eventually had to shoot them down. Only one remains because someone stole his last arrow.
Apollo, of course, is a Greek god associated with the sun. Hence the awkwardness between them.
What I like about this is that Apollo is an archer as well, which makes me think this was at some get together of legendary archers.
